    Canada geese (Branta canadensis) have become common in many urban areas, often creating nuisance problems for human residents. The presence of urban geese has raised concerns about the spread of disease, increased erosion, excessive noise, eutrophication of waterways, and general nuisance problems. Goose populations have grown due to an increase in urbanization resulting in an abundance of high quality food (urban grass) and suitable nesting sites, as well as a decrease in some predators. I monitored nest predation in the Chicago suburbs during the 2004 and 2005 nesting seasons using 3 nest monitoring techniques to identify predators: video cameras, plasticine eggs, and sign from nest using a classification tree analysis. Of 58 nests monitored in 2004 and 286 in 2005, only raccoons (Procyon lotor) and coyotes (Canis latrans) were identified as nest predators. Raccoons were responsible for 22-25% of depredated nests, but were rarely capable of depredating nests that were actively defended by a goose. Coyotes were responsible for 75-78% of all Canada goose nest depredation and were documented killing one adult goose and feeding on several others. The coyote is a top-level predator that had increased in many metropolitan areas in recent years. To determine if coyotes were actively hunting geese or eggs during the nesting season, I analyzed coyote habitat selection between nesting and pre-nesting or post-nesting seasons. Coyote home ranges (95% Minimum Convex Polygon) were calculated for 19 coyotes to examine third order habitat selection related to goose nest abundance. A 100 m buffer (buffer habitat) was created and centered on each waterway edge and contained 90% of all nests. Coyotes showed selection for habitats during all seasons. Buffer habitat was the top ranked habitat in both pre-nesting and nesting seasons, but dropped to third ranked in post-nesting season. Habitat selection across seasons was compared using a repeated measures MANOVA. Habitat selection

    1980-01-01

    The western Canada goose (Branta canadensis moffitti) was divided into a Rocky Mountain population (RMP) and a Pacific population (PP) on the basis of band recovery patterns examined in this study and recovery data from other investigators. Habitat information obtained from nine cooperating wildlife agencies within the RMP's range provided a base line for evaluating future changes in nesting, molting, and wintering areas. The habitat inventory indicated that none of the seasonal habitats were currently limiting the size of the RMP. The RMP's range is divided into 15 reference areas and these are briefly described. Past studies of Canada geese in the Intermountain Region are reviewed. Topics covered in the discussion of breeding biology are nesting chronology, spring population composition, breeding age, clutch size, nesting success. artificial nesting structures, and gosling survival. Much of the mortality of Canada geese occurs before the birds are fledged. Man-made nesting structures reduce losses during incubation. but research is needed on the relations between brooding sites and gosling survival. Some western Canada geese, mainly prebreeders and unsuccessful nesters, make molt migrations to and from molting areas during and after the brood-rearing season. More than half of these molt-migrants are yearlings too young to nest; there are indications that even some successful nesters leave nesting areas to molt before the fledging of their offspring. Geese 2 years old or older may serve as guides to traditional molting areas for the first-time migrants (i.e., yearlings). Lack of disturbance appears to influence selection of specific molting areas within the nesting range of moffitti, whereas movements of molters out of the Intermountain Region may be related to the evolution of this subspecies. Apparently. molters of both the PP and RMP that leave the Region go to the Northwest Territories of Canada. Although the taxonomic status of moffitti as related to the

    Shallow lakes are dominant features in subarctic and Arctic landscapes and are responsive to multiple stressors, which can lead to rapid changes in limnological regimes with consequences for aquatic resources. We address this theme in the coastal tundra region of Wapusk National Park, western Hudson Bay Lowlands (Canada), where climate has warmed during the past century and the Lesser Snow Goose (LSG; Chen caerulescens caerulescens) population has grown rapidly during the past ∽40 years. Integration of limnological and paleolimnological analyses documents profound responses of productivity, nutrient cycling, and aquatic habitat to warming at three ponds ("WAP 12", "WAP 20", and "WAP 21″), and to LSG disturbance at the two ponds located in an active nesting area (WAP 20, WAP 21). Based on multiparameter analysis of (210)Pb-dated sediment records from all three ponds, a regime shift occurred between 1875 and 1900 CE marked by a transition from low productivity, turbid, and nutrient-poor conditions of the Little Ice Age to conditions of higher productivity, lower nitrogen availability, and the development of benthic biofilm habitat as a result of climate warming. Beginning in the mid-1970s, sediment records from WAP 20 and WAP 21 reveal a second regime shift characterized by accelerated productivity and increased nitrogen availability. Coupled with 3 years of limnological data, results suggest that increased productivity at WAP 20 and WAP 21 led to atmospheric CO2 invasion to meet algal photosynthetic demand. This limnological regime shift is attributed to an increase in the supply of catchment-derived nutrients from the arrival of LSG and their subsequent disturbance to the landscape. Collectively, findings discriminate the consequences of warming and LSG disturbance on tundra ponds from which we identify a suite of sensitive limnological and paleolimnological measures that can be utilized to inform aquatic ecosystem monitoring.

    Reiter, M.E.; Andersen, D.E.

    2011-01-01

    We examined factors influencing Canada Goose (Branta canadensis interior) annual nest success, including the relative abundance of collared lemmings (Dicrostonyx richardsoni), arctic fox (Alopex lagopus) den occupancy, nest density, and spring phenology using data collected during annual Canada Goose breeding area surveys at Cape Churchill, Manitoba. Nest density and arctic fox den occupancy strongly influenced Canada Goose nest success. High nest density resulted in higher nest success and high den occupancy reduced nest success. Nest success was not influenced by lemming abundance in the current or previous year as predicted by the "bird-lemming" hypothesis. Reducing arctic fox abundance through targeted management increased nest survival of Canada Geese; a result that further emphasizes the importance of arctic fox as nest predators in this system. The spatial distribution of nest predators, at least for dispersed-nesting geese, may be most important for nest survival, regardless of the abundance of small mammals in the local ecosystem. Further understanding of the factors influencing the magnitude and variance in arctic fox abundance in this region, and the spatial scale at which these factors are realized, is necessary to fully explain predator-prey-alternative prey dynamics in this system. ?? 2011 by the Wilson Ornithological Society.

    . At an exclosure elevation of 10 cm and with a soft, mucky substrate, we are assuming that non-goose herbivores such as fish and turtles still have free access to the fenced plots. Annual wildrice (Zizania aquatica), known from previous studies to be especially palatable to Canada geese, has seen the greatest impact from partial access to the fenced plots by mature geese, moving from an overwhelming dominant in the initially-vegetated plots to a minor presence there by August 2011. Interestingly, pickerelweed (Pontederia cordata), also known to be highly palatable to Canada geese, has so far shown only minor herbivory in the fenced plots. By August 2011, pickerelweed had actually increased to significantly greater cover levels in the fenced plots compared to the unfenced control plots. In conclusion, the first three years of data document that vegetation exposed to full herbivory by resident and nonmigratory Canada geese for three years in the unfenced control plots showed significantly lower total vegetative cover and species richness compared to the vegetation in the fenced plots, which experienced reduced herbivory by resident and nonmigratory Canada geese. These effects were documented for modules located in both initially-vegetated and initially-unvegetated habitats.

  8. Canada's population: growth and dualism.

    Science.gov (United States)

    Beaujot, R P

    1978-04-01

    In Canada the current 1.3% population growth rate is causing some concern. Those concerned argue that such a rate of growth in combination with high levels of consumption could jeopardize the country's resource base and its comfortable style of living. Many Canadians are questioning high levels of immigration, for now that the fertility level is below replacement level, net immigration contributes substantially to population growth (over 1/3 in 1976). The growing proportion of non-Europeans among recent immigrants is causing resentment, and, in a tight job market, immigrants are regarded as threats to the World War 2 baby boom cohort who are now at working ages. The baby boom generation also puts stress on housing and health services, and it will increase the need for pension checks as it ages. Although French fertility is no longer high and immigration is no longer dominated by the British, the French group's 200-year struggle to preserve its identity continues on in the current effort of the Quebec government to enforce the use of French language by law within that province. Geography and climate dictate another demographic fact that divides the country and pervades its history. In addition to intense regionalism, uneven population distribution is responsible for 2 other concerns: the rapid growth of several already large cities and depopulation of many small communities. Focus in this discussion is on Canada's population growth in the past and as projected for the future, historical and current fertility, mortality and immigration trends, the search for a new immigration policy, the impact of the baby boom generation on the population's age structure and the problems this creates, and recent shifts in population distribution and in the country's ethnic and linguistic makeup. The population policy proposals evolved thus far involve to a great extent the use of immigration as a lever for achieving given population objectives.

    Avian cholera is reported for the first time in Canada geese, Branta canadensis, of the Mississippi Valley population. The disease was detected in weekly surveillance transects and was responsible for the loss of about 850 geese during the winter of 1978-1979 at localized areas in southern Illinois. Necropsies performed on 480 geese that died at Union County Conservation Area and on 133 birds at Horseshoe Lake Conservation Area during January and February 1979 revealed that the majority of losses (64%) were caused by avian cholera. Lead poisoning was responsible for the death of 14% of the geese analyzed and the remaining 22%, most of which were decomposed, were undiagnosed. Lethal lead levels and Pasteurella multocida occurred concomitantly in a few instances.

    1991-04-01

    Overall, the nesting population of Great Basin Canada geese (Branta canadensis moffitti) on the Hanford Site in southcentral Washington State is doing well and appears to be increasing. The average annual total nests for the period 1981 through 1990 was 215 nests, which is slightly above the average reported for the period 1950 through 1970. The nesting population has shifted its nucleus from upriver islands (1--10) to the lower river islands (11--20) with over 70% of the present-day nesting occurring on Islands 17, 18, 19, 20. The annual percent-successful nests from 1981 through 1990 was 80%. This is above the 71% reported for 1950 to 1970, but is below the 82% reported for 1971 to 1980. Average annual clutch size for 1981 to 1990 was 6.05, which is above the 1971-to-1980 average of 5.6 and the 1950-to-70 average of 5.5. Next desertions for 1981 to 1990 averaged 8%. This rate is well below the 14% reported for 1950 to 1970. Predators were responsible for an annual predation rate of 9% from 1981 to 1990. This is below the 1950-to-1970 annual average predation rate of 14%. Flooding losses to nests were low during the 1980s, except for 1989 and 1990 when 6% and 9% of the total nests, respectively, were destroyed by flooding. 9 refs., 4 figs., 1 tab.

    2013-01-01

    Herbivory has played a major role in dictating vegetation abundance and species composition at Kingman Marsh in Anacostia Park, Washington, D.C., since restoration of this tidal freshwater wetland was initiated in 2000. The diverse and robust vegetative cover that developed in the first year post-reconstruction experienced significant decimation in the second year, after the protective fencing was removed, and remained suppressed throughout the five-year study period. In June 2009 a herbivory study was initiated to document the impacts of herbivory by resident and nonmigratory Canada geese (Branta canadensis) to vegetation at Kingman Marsh. Sixteen modules consisting of paired fenced plots and unfenced control plots were constructed. Eight of the modules were installed in vegetated portions of the restoration site that had been protected over time by pre-existing fencing, while the remaining eight modules were placed in portions of the site that had not been protected over time and were basically unvegetated at the start of the experiment. Exclosure fencing was sufficiently elevated from the substrate level to allow access to other herbivores such as fish and turtles, while hopefully excluding mature Canada geese. The study was designed with an initial exclosure elevation of 20 cm. This elevation was chosen based on the literature, as adequate to exclude mature Canada geese, while maximizing access to other herbivores such as fish and turtles. Repeated measures analysis of variance (ANOVA) was used to analyze the differences between paired fenced and unfenced control plots for a number of variables including total vegetative cover. Differences in total vegetative cover were not statistically significant for the baseline data collected in June 2009. By contrast, two months after the old protective fencing was removed from the initially-vegetated areas to allow Canada geese access to the unfenced control plots, total vegetative cover had declined dramatically in the

    2014-01-01

    We explored the application of dynamic-optimization methods to the problem of pink-footed goose (Anser brachyrhynchus) management in western Europe. We were especially concerned with the extent to which uncertainty in population dynamics influenced an optimal management strategy, the gain in management performance that could be expected if uncertainty could be eliminated or reduced, and whether an adaptive or robust management strategy might be most appropriate in the face of uncertainty. We combined three alternative survival models with three alternative reproductive models to form a set of nine annual-cycle models for pink-footed geese. These models represent a wide range of possibilities concerning the extent to which demographic rates are density dependent or independent, and the extent to which they are influenced by spring temperatures. We calculated state-dependent harvest strategies for these models using stochastic dynamic programming and an objective function that maximized sustainable harvest, subject to a constraint on desired population size. As expected, attaining the largest mean objective value (i.e., the relative measure of management performance) depended on the ability to match a model-dependent optimal strategy with its generating model of population dynamics. The nine models suggested widely varying objective values regardless of the harvest strategy, with the density-independent models generally producing higher objective values than models with density-dependent survival. In the face of uncertainty as to which of the nine models is most appropriate, the optimal strategy assuming that both survival and reproduction were a function of goose abundance and spring temperatures maximized the expected minimum objective value (i.e., maxi–min). In contrast, the optimal strategy assuming equal model weights minimized the expected maximum loss in objective value. The expected value of eliminating model uncertainty was an increase in objective value

    Tuggle, Benjamin N.; Crites, John L.

    1984-01-01

    Kidneys from 309 Interior Canada geese from three locations in the Mississippi Flyway were examined for renal coccidia. Oocysts and/or young zygotes of Eimeria sp. were found in 6.8% of goose kidneys sampled. Only one type of renal coccidian oocyst was observed. Significantly more immature geese were infected than adults; however, there was no significant difference observed between the prevalences of infection in male and female birds. A host cellular response to zygotes and oocysts was noted in the majority of infected adult geese. Heavily infected kidneys were hypertrophic with minute foci on the surface of the organ. Histological examinations showed large numbers of unsporulated oocysts accumulated in distended collecting tubules, resulting in pressure necrosis to adjacent tissue and urate retention. Zygotes were observed in the cytoplasm of tubule cells and extracellularly in interstitial tissue. Infected tubule cells were characterized by the peripheral location of the nuclei, cytoplasmic basophilia, and cellular hypertrophy. This is the first report of an Eimeria sp. in the kidneys of Canada geese of the Mississippi Valley population.

  20. Comparison of the egg flotation and egg candling techniques for estimating incubation day of Canada Goose nests

    Science.gov (United States)

    Reiter, M.E.; Andersen, D.E.

    2008-01-01

    Both egg flotation and egg candling have been used to estimate incubation day (often termed nest age) in nesting birds, but little is known about the relative accuracy of these two techniques. We used both egg flotation and egg candling to estimate incubation day for Canada Geese (Branta canadensis interior) nesting near Cape Churchill, Manitoba, from 2000 to 2007. We modeled variation in the difference between estimates of incubation day using each technique as a function of true incubation day, as well as, variation in error rates with each technique as a function of the true incubation day. We also evaluated the effect of error in the estimated incubation day on estimates of daily survival rate (DSR) and nest success using simulations. The mean difference between concurrent estimates of incubation day based on egg flotation minus egg candling at the same nest was 0.85 ?? 0.06 (SE) days. The positive difference in favor of egg flotation and the magnitude of the difference in estimates of incubation day did not vary as a function of true incubation day. Overall, both egg flotation and egg candling overestimated incubation day early in incubation and underestimated incubation day later in incubation. The average difference between true hatch date and estimated hatch date did not differ from zero (days) for egg flotation, but egg candling overestimated true hatch date by about 1 d (true - estimated; days). Our simulations suggested that error associated with estimating the incubation day of nests and subsequently exposure days using either egg candling or egg flotation would have minimal effects on estimates of DSR and nest success. Although egg flotation was slightly less biased, both methods provided comparable and accurate estimates of incubation day and subsequent estimates of hatch date and nest success throughout the entire incubation period. ?? 2008 Association of Field Ornithologists.

    Avian feces contaminate waterways but contribute fewer human pathogens than human sources. Rapid identification and quantification of avian contamination would therefore be useful to prevent overestimation of human health risk. We used subtractive hybridization of PCR-amplified gull fecal 16S RNA genes to identify avian-specific fecal rRNA gene sequences. The subtracters were rRNA genes amplified from human, dog, cat, cow, and pig feces. Recovered sequences were related to Enterobacteriaceae (47%), Helicobacter (26%), Catellicoccus (11%), Fusobacterium (11%), and Campylobacter (5%). Three PCR assays, designated GFB, GFC, and GFD, were based on recovered sequence fragments. Quantitative PCR assays for GFC and GFD were developed using SYBR green. GFC detected down to 0.1 mg gull feces/100 ml (corresponding to 2 gull enterococci most probable number [MPN]/100 ml). GFD detected down to 0.1 mg chicken feces/100 ml (corresponding to 13 Escherichia coli MPN/100 ml). GFB and GFC were 97% and 94% specific to gulls, respectively. GFC cross-reacted with 35% of sheep samples but occurred at about 100,000 times lower concentrations in sheep. GFD was 100% avian specific and occurred in gulls, geese, chickens, and ducks. In the United States, Canada, and New Zealand, the three markers differed in their geographic distributions but were found across the range tested. These assays detected four important bird groups contributing to fecal contamination of waterways: gulls, geese, ducks, and chickens. Marker distributions across North America and in New Zealand suggest that they will have broad applicability in other parts of the world as well. PMID:22081573

    Full Text Available Abstract Background The objective of the paper is to compare population health in the United States (US and Canada. Although the two countries are very similar in many ways, there are potentially important differences in the levels of social and economic inequality and the organization and financing of and access to health care in the two countries. Methods Data are from the Joint Canada/United States Survey of Health 2002/03. The Health Utilities Index Mark 3 (HUI3 was used to measure overall health-related quality of life (HRQL. Mean HUI3 scores were compared, adjusting for major determinants of health, including body mass index, smoking, education, gender, race, and income. In addition, estimates of life expectancy were compared. Finally, mean HUI3 scores by age and gender and Canadian and US life tables were used to estimate health-adjusted life expectancy (HALE. Results Life expectancy in Canada is higher than in the US. For those Conclusions The population of Canada appears to be substantially healthier than the US population with respect to life expectancy, HRQL, and HALE. Factors that account for the difference may include access to health care over the full life span (universal health insurance and lower levels of social and economic inequality, especially among the elderly.

    mediated response to the presence of E. clarkei oocysts and endogenous stages was seen in 83.3% of infected adult geese, but only 20% of immature geese showed a macrophage response to the infective stages of this parasite. A massive E. clarkei infection caused the death of one goose collected at Horicon National Wildlife Refuge. Amidostomiasis, epomidiostomiasis, and renal coccidiosis were important pathogenic diseases in the Mississippi Valley Population Canada geese but did not directly cause significant mortality in the population.

    We monitored lead exposure in Eastern Prairie Population Canada geese during summer-winter, 1986-1987 and 1987-1988 at 5 areas. Blood lead concentrations in geese trapped during summer at Cape Churchill Manitoba were below levels indicative of recent lead exposure (0.18 ppm). Geese exposed to lead (≥0.18 ppm blood lead) increased to 7.6% at Oak Hammock Wildlife Management Area (WMA), southern Manitoba, where lead shot was still in use, and to 10.0% at Roseau River WMA, northern Minnesota, when fall-staging geese were close to a source of lead shot in Manitoba. Proportion of birds exposed to lead dropped to National Wildlife Refuge in Missouri, 4.9% of all geese showed exposure to lead before the hunting season. Lead exposure rose to 10.0% after hunting ended and then decreased to 5.2% in late winter. Incidence of lead shot in gizzards and concentrations of lead in livers supported blood assay data. Soil samples indicated that lead shot continues to be available to geese at Swan Lake, even though the area was established as a non-toxic shot zone in 1978. Steel shot zones have reduced lead exposure in the Eastern Prairie Population, but lead shot persists in the environment and continues to account for lead exposure and mortality in Eastern Prairie Population Canada geese.

    Theory predicts persistence of long-term family relationships in vertebrates will occur until perceived fitness costs exceed benefits to either parents or offspring. We examined whether increased breeding probability and survival were associated with prolonged parent-offspring and sibling-sibling relationships in a long-lived Arctic migrant herbivore, the Greenland white-fronted goose (Anser albifrons flavirostris). Although offspring associated with parents for 1-13 years, 79 % of these associations lasted two or less years. Only 65 (9.9 %) of the 656 marked offspring bred once in their lifetime, and just 16 (2.4 %) bred twice or more. The probability of birds with siblings breeding successfully in a subsequent year was credibly greater than that of independent birds at ages 5, 6, and 7. Survival of offspring with parents was credibly greater than that of independent/nonbreeder birds at all possible ages (i.e., ages 2-7+). A cost-benefit matrix model utilizing breeding and survival probabilities showed that staying with family groups was favored over leaving until age 3, after which there were no credible differences between staying and leaving strategies until the oldest ages, when leaving family groups was favored. Thus, most birds in this study either departed family groups early (e.g., at age 2, when the "stay" strategy was favored) or as predicted by our cost-benefit model (i.e., at age 3). Although extended family associations are a feature of this population, we contend that the survival benefits are not sufficient enough to yield clear fitness benefits, and associations only persist because parents and offspring mutually benefit from their persistence.

    2006-05-01

    We examined 395 mtDNA control-region sequences from Greenlandic Inuit and Canadian Kitikmeot Inuit with the aim of shedding light on the migration history that underlies the present geographic patterns of genetic variation at this locus in the Arctic. In line with previous studies, we found that Inuit populations carry only sequences belonging to haplotype clusters A2 and D3. However, a comparison of Arctic populations from Siberia, Canada, and Greenland revealed considerable differences in the frequencies of these haplotypes. Moreover, large sample sizes and regional information about birthplaces of maternal grandmothers permitted the detection of notable differences in the distribution of haplotypes among subpopulations within Greenland. Our results cast doubt on the prevailing hypothesis that contemporary Inuit trace their all of their ancestry to so-called Thule groups that expanded from Alaska about 800-1,000 years ago. In particular, discrepancies in mutational divergence between the Inuit populations and their putative source mtDNA pool in Siberia/Alaska for the two predominant haplotype clusters, A2a and A2b, are more consistent with the possibility that expanding Thule groups encountered and interbred with existing Dorset populations in Canada and Greenland.

  18. Canada

    International Nuclear Information System (INIS)

    Nuclear research and development in Canada started in the 1940s as a responsibility of the federal government. An engineering design team was established at Chalk River, Ontario, to carry out research on heavy water moderated lattices. A zero-energy heavy water moderated research reactor, ZEEP, was built and achieved criticality in September 1945; it was in fact the first human-made operating reactor outside the USA. In 1947, the 20 MW heavy water moderated national research experimental reactor (NRX) started up. It served as one of the most valuable research reactors in the world, and provided the basis for Canada's development of the very successful CANDU series of pressurised heavy water reactors (PHWR) for power generation. Atomic Energy of Canada Limited (AECL) was established in 1952 as a federal Crown Corporation. It has both a public and a commercial mandate. AECL has overall responsibility for Canada's nuclear research and development programme (its public mandate) as well as for the Canadian reactor design (CANDU), engineering and marketing programme (its commercial mandate). Nuclear energy in Canada is a $5 billion per-year industry, representing about 150 firms, 21 000 direct jobs and 10 000 indirect jobs, and ∼$1.2 billion in exports - the value to the country's economy is much higher than the research and development funding provided by the federal government. The CANDU nuclear reactor system was developed by AECL in close collaboration with the Canadian nuclear industry, and in particular with Ontario Hydro (now Ontario Power Generation). Currently, Canada operates 17 CANDU reactors, which contribute 16% of the country's current electricity consumption. There are also 12 CANDU reactors operating abroad (in Argentina, China, India, the Republic of Korea, Pakistan and Romania). AECL is now developing the 'third generation plus' Advanced CANDU Reactor (ACR-1000), and also has the leading role internationally in developing the Generation IV

    While concern grows over the increasing numbers of exotic mute swans (Cygnus olor) on the Chesapeake Bay, less attention seems to be given to the highly familiar and native Canada goose (Branta canadensis) which has over time developed unprecedented nonmigratory, or resident, populations. Although nuisance flocks of Canada geese have been well advertised at city parks, athletic fields, and golf courses over the past three decades, recent expansion of populations to an estimated one million birds in the Atlantic Flyway, and to over 100,000 in Maryland, carries a threat of broader ecological consequences.

  20. Sequence Analysis of Mitochondrial DNA D-loop Region in Xinjiang Goose

    2012-01-01

    [Objective] The sequences of mitochondrial DNA D-loop region of Xinjiang Goose with three different colors of plumage were analyzed in order to study the genetic diversity of Xinjiang Goose, as well as the phylogeny and evolution. [Method] Ten geese were selected randomly from the core populations of grey-, mosaic- and white-plumaged Xinjiang Goose respectively with a total number of thirty as experi- mental materials, of which the blood samples were collected from the largest vein under the wing (brachial vein) for DNA extraction. Sequences of mitochondrial DNA D-loop regions were determined using DNA sequencing technology to analyze the polymorphism. In addition, the genetic distances among different populations were estimated through the comparison with the reference sequences. [Resull] The con- tents of A, G, C and T nucleotides in the D-loop region of Xinjiang Goose were 28.85%, 17.05%, 25.38% and 28.72%, respectively. The average haplotype diversity and nucleotide diversity of Xinjiang Goose were 0.583 and 0.056. Xinjiang Goose and Greylag Goose were clustered into the same group. [Conclusion] The results showed that Xinjiang Geese with three different colors of plumage all descend from Greylag Goose (Anser anser).

    This paper reports that the Canadian oil and natural gas sector is in for another grim year in 1992. Further streamlining to enhance operating efficiencies and control costs is the first order of the day. About $4 billion worth of producing properties remains on the market, as corporate focus continues to shift to core properties. New management structures put in place in the last two years will be severely tested to improve the sector's financial performance. Massive write-downs in 1990 and 1991 have put balance sheets in much better shape for improved financial performance in the future. Although new long-term debt exceeded redemptions in 1991, largely because of debt- financing of major capital projects, individually most companies are in better shape through significant debt repayment or restructuring. The substantial reductions in interest rates will also help to enhance discretionary cash flow. At this stage, everything appears to be in place to expect that 1992 will represent the bottom of the down-cycle for Canada

    The Southern Hudson Bay (SH) population of polar bears (Ursus maritimus) resides in a seasonal sea ice environment and is the most southerly population in the species’ range. Therefore, SH polar bears may be among the first to show negative effects associated with climate warming and consequent loss of sea ice. Polar bears in the neighboring Western Hudson Bay (WH) population have declined significantly in body condition since the mid-1980s, and a recent study indicated that the size of the WH population declined by about 22% between 1987 and 2004. Similarly, SH bears have shown a significant decline in body condition since the mid-1980s, and an assessment of the current status of the SH population was therefore needed. We applied open population capture-recapture models to data collected from 1984-86 and 1999- 2005 to estimate population size and survival. The size of the SH population appears to be unchanged from the mid-1980s (1984-1986: 641, 95% CI = 401, 881) vs. 2003-2005: 681 (95% CI = 401, 961). Point estimates of survival for subadults and adult females were 94% (95% CI = 68%, 100%) in 1984-1985 to 89% (95% CI = 79%, 99%) in 2003-2005, but imprecision exhibited by overlap of the confidence intervals prevented us from unequivocally concluding that this 5% decline in survival was not a chance occurrence. Similarly, a decline of 7% in survival was estimated for subadult and adult males over the same time period (male survival estimates = 88% (95% CI = 77%, 100%) in 1984-1985; 81% (95% CI = 66%, 96%), but again we could not unequivocally conclude that this decline was not chance. There was weak evidence of lower survival of cubs, yearlings, and senescent adults in the recent time period. This, combined with the evidence of significant declines in body condition for all age and sex classes, which were greatest for pregnant females and subadults, suggests this population may be under increased stress at this time. However, we did not find any clear

    Full Text Available Interest has been increasing in regulating the location and number of tobacco vendors as part of a comprehensive tobacco control program. The objective of this paper is to examine the distribution of tobacco outlets in a large jurisdiction, to assess: (1 whether tobacco outlets are more likely to be located in vulnerable areas; and (2 what proportion of tobacco outlets are located close to schools. Retail locations across the Province of Ontario from Ministry of Health Promotion data were linked to 2006 Census data at the neighbourhood level. There was one tobacco retail outlet for every 1,000 people over age 15 in Ontario. Density of outlets varied by public health unit, and was associated with the number of smokers. Tobacco outlets were more likely to be located in areas that had high neighbourhood deprivation, in both rural and urban areas. Outlets were less likely to be located in areas with high immigrant populations in urban areas, with the reverse being true for rural areas. Overall, 65% of tobacco retailers were located within 500 m of a school. The sale of tobacco products is ubiquitous, however, neighbourhoods with lower socio-economic status are more likely to have easier availability of tobacco products and most retailers are located within walking distance of a school. The results suggest the importance of policies to regulate the location of tobacco retail outlets.

    2007-04-01

    Full Text Available Recovery planning for the boreal population of woodland caribou is a complex task, spanning eight Canadian provinces and territories. To accommodate unique situations across the country, recovery planning for this Species at Risk Act-listed threatened species is occurring at both provincial/ territorial and national levels. The national recovery strategy strives to identify nationally important issues and provide direction for provinces and territories as they plan and implement boreal caribou recovery within their jurisdictions. The national vision is to conserve and recover boreal caribou and their habitat across Canada. Specific goals are to: 1 Prevent extirpation of local boreal caribou populations from all existing caribou ranges; and 2 Maintain or enhance local boreal caribou populations at or to self-sustaining levels within all existing caribou ranges; and 3 Maintain or enhance boreal caribou habitat to support self-sustaining local populations. Nineteen broad national approaches are identified. These approaches include items relating to: habitat planning and management, caribou population monitoring and management, management of human-caused mortality, management of other wildlife species, consideration of government legislation and policy,promotion of stewardship and public outreach, and research. Specific outcomes are provided for each stated recovery approach.

    Full Text Available The paper deals with the study of the goose eggs behaviour under compressive loading between two plates using testing device TIRATEST. The influences of the loading orientation as well as the effect of compressive velocity are studied. 226 eggs from Landes geese were chosen for the experiment. Eggs have been loaded between their poles and in the equator plane. Five different compressive velocities (0.0167, 0.167, 0.334, 1.67 and 5 mm.s-1 were used. The increase in rupture force with loading rate was observed for loading in all direction (along main axes. Dependence of the rupture force on loading rate was quantifies and described. The highest rupture force was obtained when the eggs were loaded along their axes of symmetry (X-axis. Compression in the equator plane (along the Z-axis required the least compressive force to break the eggshells. The eggshell strength was described by the rupture force, specific rupture deformation and by the absorbed energy. The rupture force is highly dependent on compression speeds. The dependence of the rupture force on the compression velocity can be described by a power function. The same is valid for the rate dependence of the energy absorbed by the egg up to the fracture. The rate sensitivity of the Goose's eggshells strength is significantly higher than that reported for the hen's eggs

    Full Text Available Small, at-risk populations are those for which accurate demographic information is most crucial to conservation and recovery, but also where data collection is constrained by logistical challenges and small sample sizes. Migratory animals in particular may experience a wide range of threats to survival and reproduction throughout each annual cycle, and identification of life stages most critical to persistence may be especially difficult for these populations. The endangered eastern Canadian breeding population of Piping Plover (Charadrius melodus melodus was estimated at only 444 adults in 2005, and extensive effort has been invested in conservation activities, reproductive monitoring, and marking of individual birds, providing a comprehensive data set on population dynamics since 1998. We used these data to build a matrix projection model for two Piping Plover population segments that nest in eastern Canada in order to estimate both deterministic and stochastic rates of population growth (λd and λs, respectively. Annual population censuses suggested moderate growth in abundance between 1998–2003, but vital rate estimates indicated that this temporary growth may be replaced by declines in the long term, both in southern Nova Scotia (λd = 1.0043, λs = 0.9263 and in the Gulf of St. Lawrence (λd = 0.9651, λs = 0.8214. Nonetheless, confidence intervals on λ estimates were relatively wide, highlighting remaining uncertainty in future population trajectories. Differences in projected growth between regions appear to be driven by low estimated juvenile post-fledging survival in the Gulf, but threats to juveniles of both population segments following departure from nesting beaches remain unidentified. Similarly, λ in both population segments was particularly sensitive to changes in adult survival as expected for most migratory birds, but very little is understood about the threats to Piping Plover survival during migration and overwintering

    The genomic structure and composition of an avian metapneumovirus (aMPV) recently isolated from wild Canada geese (goose 15a/01) in the United States, together with its replication, virulence, and immunogenicity in domestic turkeys, were investigated. The sizes of seven of the eight genes, sequence identity, and genome organization of goose aMPV were similar to those of turkey aMPV subtype C (aMPV/C) strains, indicating that it belonged to the subtype. However, the goose virus contained the largest attachment (G) gene of any pneumovirus or metapneumovirus, with the predicted G protein of 585 amino acids (aa) more than twice the sizes of G proteins from other subtype C viruses and human metapneumovirus and more than 170 aa larger than the G proteins from the other aMPV subtypes (subtypes A, B, and D). The large G gene resulted from a 1,015-nucleotide insertion at 18 nucleotides upstream of the termination signal of the turkey aMPV/C G gene. Three other aMPV isolates from Canada geese had similarly large G genes, whereas analysis of recent aMPV strains circulating in U.S. turkeys did not indicate the presence of the goose virus-like strain. In vitro, the goose virus replicated to levels (2 x 10(5) to 5 x 10(5) 50% tissue culture infective dose) comparable to those produced by turkey aMPV/C strains. More importantly, the virus replicated efficiently in the upper respiratory tract of domestic turkeys but with no clinical signs in either day-old or 2-week-old turkeys. The virus was also horizontally transmitted to naïve birds, and turkey infections with goose 15a/01 induced production of aMPV-specific antibodies. Challenging day-old or 2-week-old turkeys vaccinated with live goose aMPV resulted in lower clinical scores in 33% of the birds, whereas the rest of the birds had no detectable clinical signs of the upper respiratory disease, suggesting that the mutant virus may be a safe and effective vaccine against aMPV infection outbreaks in commercial turkeys.

    Full Text Available We describe the protocols of two mark-resight abundance surveys, using temporary dye-marks, for the Aishihik woodland caribou (Rangifer tarandus caribou and wood bison (Bison bison athabascae populations (herds in the southwest Yukon Territory, Canada. We also provide recommendations based on experiences from these surveys for biologists and managers considering this approach. The Aishihik woodland caribou herd was the focus of intensive management in the 1990s aimed at recovering the herd. Following recovery activities, a target size of 2000 animals was determined and the Champagne-Aishihik Traditional Territory Community-Based Wildlife Management Plan recommended an estimate of the herd’s size be completed before the year 2013. We used an aerial mark-resight approach to estimate the herd’s size in March 2009. Caribou (n = 59 were marked from a helicopter with temporary dye, delivered via a CO2-powered rifle. Two independent resighting sessions were subsequently carried out via helicopter. The herd was estimated at 2044 animals (90% CI: 1768 – 2420 with an overall resighting rate of 0.47. The mean annual growth rate (λ of the herd from 1997 – 2009 was 1.05 (SE = 0.01. The Aishihik wood bison herd was estimated at 1151 (90% CI: 998 – 1355. Our study suggests that ungulates temporarily marked with dye can be successfully used to obtain statistically sound population estimates.

This pattern is changing with increased life expectancy, a growing population, and a poor social environment that influences risk behaviors, metabolic conditions, and disparities in screening uptake. These factors alone do not fully explain differences in cancer risk between populations, as genetic susceptibility and environmental factors also have significant influence. However, genetics and environment are difficult to modify. This study compared modifiable behavioral risk factors and metabolic-associated conditions for men and women, and cancer screening practices of women, between First Nations living on-reserve and a non-First Nations Manitoba rural population (Canada.Methods: The study used data from the Canadian Community Health Survey and the Manitoba First Nations Regional Longitudinal Health Survey to examine smoking, binge drinking, metabolic conditions, physical activity, fruit/vegetable consumption, and cancer-screening practices.Results: First Nations on-reserve had significantly higher rates of smoking (P < 0.001, binge drinking (P < 0.001, obesity (P < 0.001 and diabetes (P < 0.001, and less leisure-time physical activity (P = 0.029, and consumption of fruits and vegetables (P < 0.001.

    Full Text Available Based on a study of a perennial herb Anemone patens L. (Ranunculaceae in a variety of natural habitats in Saskatchewan, Canada, eight life stages (seed, seedling, juvenile, immature, vegetative, generative, subsenile, and senile are distinguished and characterized in detail. The species ontogenetic growth patterns are investigated. A. patens has a long life cycle that may last for several decades which leads to the formation of compact clumps. The distribution and age of clumps vary substantially in different environments with different levels of disturbance. The plant ontogeny includes the regular cycle with reproduction occurring through seeds. There is an optional subsenile vegetative disintegration at the end of the life span. The following variations in the life cycle of A. patens are identified: with slower development in young age, with an accelerated development, with omission of the generative stage, with retrogression to previous life stages in mature age, and with vegetative dormancy. The range of variations in the life cycle of A. patens may play an important role in maintaining population stability in different environmental conditions and management regimes.

    Full Text Available Abstract Background The effect of antioxidants on breast cancer is still controversial. Our objective was to assess the association between antioxidants and breast cancer risk in a large population-based case-control study. Methods The study population included 2,362 cases with pathologically confirmed incident breast cancer (866 premenopausal and 1,496 postmenopausal and 2,462 controls in Canada. Intakes of antioxidants from diet and from supplementation as well as other potential risk factors for breast cancer were collected by a self-reported questionnaire. Results Compared with subjects with no supplementation, 10 years or longer supplementation of zinc had multivariable-adjusted odds ratios (OR and 95% confidence intervals (CI of 0.46 (0.25-0.85 for premenopausal women, while supplementation of 10 years or longer of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc had multivariable-adjusted ORs (95% CIs of 0.74 (0.59, 0.92, 0.58 (0.36, 0.95, 0.79 (0.63-0.99, 0.75 (0.58, 0.97, and 0.47 (0.28-0.78, respectively, for postmenopausal women. No significant effect of antioxidants from dietary sources (including beta-carotene, alpha-carotene, lycopene, lutein and zeaxanthin, vitamin C, vitamin E, selenium and zinc or from supplementation less than 10 years was observed. Conclusions This study suggests that supplementation of zinc in premenopausal women, and supplementation of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc in postmenopausal women for 10 or more years may protect women from developing breast cancer. However, we were unable to determine the overall effect of total dose or intake from both diet and supplement.

  6. Impacts of Water Levels on Breeding Canada Geese and Methods for Mitigation and Management in the Southern Flathead Valley, Montana, 1983-1987 Final Report.

    Kerr Hydroelectric Dam is located at the south end of Flathead Lake, controls water levels on the lake and the Flathead River below the dam, and is currently operated as a load control facility. Current operation of Kerr Dam creates the greatest yearly water level fluctuations on both the lake and river during the Canada goose (Branta canadensis moffitti) brood and nesting period. Data collected from 1980-1982 indicated that goose nest numbers on the river were lower than during the 1950's, and that brood habitat on the lake may be limiting the goose population there. Our study was conducted from 1983-1987 to determine the effects of Kerr Dam operation on Canada goose populations and habitat on the south half of Flathead Lake and the Flathead River, and to formulate management and mitigation recommendations. Nesting geese on the river appeared to be negatively affected by a lack of nest sites free from predators, and responded to available artificial nest structures with an increase in nest numbers and nesting success. Under current dam operation, river channel depths and widths do not discourage access to nesting islands by mammalian predators during some years and high predation on ground nests occurs. Intensively used brood areas on the lake and river were identified and described. Brood habitat on the lake was lower in quality and quantity than on the river due to dam operations. Gosling mortality on the lake was high, almost 2 times higher than on the river. Lake broods expended more energy obtaining food than river broods. Losses of brood habitat in the form of wet meadow marshes were documented and mitigation options developed. Management/mitigation alternatives and monitoring methods for nesting and brooding geese were identified.

    More and more sensors are getting Internet connected. Examples are cameras on cell phones, CCTV cameras for traffic control as well as dedicated security and defense sensor systems. Due to the steadily increasing data volume, human exploitation of all this sensor data is impossible for effective mission execution. Smart access to all sensor data acts as enabler for questions such as "Is there a person behind this building" or "Alert me when a vehicle approaches". The GOOSE concept has the ambition to provide the capability to search semantically for any relevant information within "all" (including imaging) sensor streams in the entire Internet of sensors. This is similar to the capability provided by presently available Internet search engines which enable the retrieval of information on "all" web pages on the Internet. In line with current Internet search engines any indexing services shall be utilized cross-domain. The two main challenge for GOOSE is the Semantic Gap and Scalability. The GOOSE architecture consists of five elements: (1) an online extraction of primitives on each sensor stream; (2) an indexing and search mechanism for these primitives; (3) a ontology based semantic matching module; (4) a top-down hypothesis verification mechanism and (5) a controlling man-machine interface. This paper reports on the initial GOOSE demonstrator, which consists of the MES multimedia analysis platform and the CORTEX action recognition module. It also provides an outlook into future GOOSE development.

    This study investigates the macroeconomic forces underlying carbon dioxide (CO{sub 2}) emissions from fossil fuel use in Canada. In keeping with the relevant literature on environmental degradation, three forces are expected to influence CO{sub 2} emissions: gross domestic product per capita (GDP/capita), population and technological change. While previous work has employed reduced-form models that allow for non-linear relationships between CO{sub 2} and GDP/capita, it has been common practice to assume linear relationships between CO{sub 2} and the latter two variables. This study tests a more flexible model using a five-region panel data set in Canada over the period 1970-2000. Findings indicate that GDP/capita is unrelated to CO{sub 2}, that an inverted U-shaped relationship exists with population, and that a U-shaped relationship exists with technology. Thus, technological and population changes are supported over the commonly hypothesized environmental Kuznets curve (EKC, an inverted U-shaped relationship between GDP/capita and environmental degradation) for affecting CO{sub 2} emissions from fossil fuel use in Canada.

    Full Text Available EnglishIn 2005, Statistics Canada published new projections of the Aboriginal populations (NorthAmerican Indians, Métis, and Inuit in Canada, the provinces and territories from 2001 to2017. To derive the number of births in these projections, the age-specific fertility rates weresimulated by fitting the Pearsonian Type I curve using the projected fertility parameters: totalfertility rates, mean ages of fertility, and modal ages of fertility. For the base period 1996 to2001, the parameters were estimated from the age-specific fertility rates derived from the 2001Census, using the “own-children method.” This paper evaluates the goodness of fit betweenthe age-specific fertility rates developed by the Type I curve and the estimated age-specificfertility rates for Aboriginal identity groups for the period 1996 to 2001 for Canada and forhigh and low fertility regions.

    Full Text Available We developed a stochastic, stage-based, matrix-projection population model to assess population viability and estimate the impact of mortality caused by hunting, illegal and incidental to the murre (Uria sp. hunt, and fox (Alopex lagopus predation on Razorbill (Alca torda populations breeding on the Gannet Islands, Labrador, the “affected” population, and Machias Seal Island, New Brunswick, the “unaffected” population. We estimated the potential population growth rate in the absence of anthropogenic mortality sources by using juvenile survival estimates from the relatively unaffected Machias Seal Island Razorbill population. We used data collected on fox predation on the Gannet Islands from 1978–2009 to estimate the change in productivity as a result of fox presence. The intrinsic growth rate (λ of the stochastic matrix based on vital rates from the Gannet Islands was 0.957±0.008 and 1.058±0.005 for Machias Seal Island. Hunting mortality reduced the predicted Gannet Islands population growth rate by 0.033, while fox predation reduced population growth rate by 0.017. These sources combined reduced the baseline population growth rate by 0.050. According to our model, the Razorbill population on Machias Seal Island appears to be growing rapidly. In contrast, the Gannet Islands population may decline, likely because of hunting. However, oceanographic differences between the two areas and uncertainty regarding dispersal behavior in this species may also contribute to the disparity between populations. Based on our findings, we make several recommendations for the conservation and management of Razorbills in Atlantic Canada.

Therefore, in this study, dried goose carcass samples were collected from the local households in Kars/Turkey and microbiologically analyzed in terms of public health risks. The total mesophilic viable count was found to be 6.58 (mean log10 CFU g-1 (100%. The number of Enterobacteriaceae was 4.85 (92.8%. Coliform bacteria was counted at the numbers of 2.98 (67.8%, while it was 3.95 (91.1% for the enterococci, 0.42 (26.7% for the clostridia, 0.04 (3.5% for the Clostridium perfringens, and 0.41 (12.5% for the coagulase positive staphylococci. The numbers of mould and yeast were 0.93 (25% and 4.81 (94.6%, respectively. Salmonellae and Bacillus cereus could not be isolated in the samples. The results indicate that the dried goose meat samples had poor hygienic quality, contained some of the pathogen microorganisms that are likely to pose a potential health risk.

    IEC 61850 is a standard for the design of electrical substation automation. Generic object oriented substation events (GOOSE) is a control model mechanism in which any format of data is grouped into a data set and transmitted within a time period of 4 milliseconds. IEC 61850 and GOOSE opens the door for a lot of technical advantages in substation protection and control applications. This presentation discussed the protection implementation and design process of a GOOSE-based digital substation. Nari-Relays Electric Company's efforts related to IEC 61850 were first presented. GOOSE in protection and control application were then presented. A network structure of a digital substation was also illustrated. It was concluded that Nari-Relays' solution of digital substation design casted a light on the GOOSE-based substation design and that Nari-Relays' IEC 61850 products provide significant benefits to users. tabs., figs.

    Population fragmentation compromises population viability, reduces a species ability to respond to climate change, and ultimately may reduce biodiversity. We studied the current state and potential causes of fragmentation in grizzly bears over approximately 1,000,000 km 2 of western Canada, the northern United States (US), and southeast Alaska. We compiled much of our data from projects undertaken with a variety of research objectives including population estimation and trend, landscape fragmentation, habitat selection, vital rates, and response to human development. Our primary analytical techniques stemmed from genetic analysis of 3,134 bears, supplemented with radiotelemetry data from 792 bears. We used 15 locus microsatellite data coupled withmeasures of genetic distance, isolation-by-distance (IBD) analysis, analysis of covariance (ANCOVA), linear multiple regression, multi-factorial correspondence analysis (to identify population divisions or fractures with no a priori assumption of group membership), and population-assignment methods to detect individual migrants between immediately adjacent areas. These data corroborated observations of inter-area movements from our telemetry database. In northern areas, we found a spatial genetic pattern of IBD, although there was evidence of natural fragmentation from the rugged heavily glaciated coast mountains of British Columbia (BC) and the Yukon. These results contrasted with the spatial pattern of fragmentation in more southern parts of their distribution. Near the Canada-US border area, we found extensive fragmentation that corresponded to settled mountain valleys andmajor highways. Genetic distances across developed valleys were elevated relative to those across undeveloped valleys in central and northern BC. In disturbed areas, most inter-area movements detected were made by male bears, with few female migrants identified. North-south movements within mountain ranges (Mts) and across BC Highway 3 were more common

    Our aim is to assess cross-national variations in prevalence of clinically relevant depression and to examine the relationships of social and health factors with depression in five diverse populations of older adults, from Canada, Brazil, Colombia and Albania. We used the data from the International Mobility in Aging Study. Clinically relevant depression was defined as a score of ≥16 on the Center for Epidemiologic Study Depression Scale (CES-D). Poisson regressions with robust covariance correction were used to estimate prevalence ratios associated with potential risk factors. Prevalence of clinically relevant depression across research sites varied widely, being consistently higher in women than in men. It was lowest in men from Brazil (6.3%) and highest in women from Albania (46.6%). Low education and insufficient income, living alone, multiple chronic conditions, and poor physical performance were all significantly associated with depression prevalence. Poor physical performance was more strongly associated with depression in men than in women. Similar factors are associated with clinically relevant depression among men and women and across research sites. The large variation in depression prevalence population rates is unexplained by the classical individual factors considered in the study suggesting the impact of country characteristics on depression among older populations.

    Full Text Available OBJECTIVE: To explore trends in access to dental care among middle-income Canadians. METHODS: A secondary data analysis of six Canadian surveys that collected information on dental insurance coverage, cost-barriers to dental care, and out-of-pocket expenditures for dental care was conducted for select years from 1978 to 2009. Descriptive analyses were used to outline and compare trends among middle-income Canadians with other levels of income as well as national averages. RESULTS: By 2009, middle-income Canadians had the lowest levels of dental insurance coverage (48.7% compared to all other income groups. They reported the greatest increase in cost-barriers to dental care, from 12.6% in 1996 to 34.1% by 2009. Middle-income Canadians had the largest rise in out-of-pocket expenditures for dental care since 1978. CONCLUSIONS: This study suggests that affordability issues in accessing dental care are no longer just a problem for the lowest income groups in Canada, but are now impacting middle-income earners as a consequence of their lack of, or decreased access to, comprehensive dental insurance.

    The Fish and Wildlife Program of the Northwest Power Planning Council calls for wildlife mitigation at hydroelectric projects in the Columbia River System. Beginning April, 1984, the Bonneville Power Administration funded a study of the effects of the operation of Hungry Horse and Kerr Dams on the western Canada goose (Branta canadensis moffittii) inhabitating the Flathead Valley of northwest Montana. The study was conducted by personnel of the Montana Department of Fish, Wildlife and Parks (MDFWP), to: (1) identify the size and productivity of this population, (2) identify current habitat conditions and losses of nesting and brood-rearing areas, (3) describe the effects of water level fluctuations on nesting and brood-rearing, and (4) identify mitigation alternatives to offset these effects. Annual pair and nest surveys were used to document the location and fate of goose nests. The number of known nesting attempts varied from 44 in 1984 to 108 in 1985, to 136 in 1986 and 134 in 1987. Fifty-four percent of the annual meeting nesting effort took place on elevated sites which were secure from the flooding and dewatering effects of fluctuating water levels. An average of 15 nests were found on stumps in the remnant Flathead River delta, however, an area strongly influenced by the operation of Kerr Dam. Annual nest losses to flooding and predation attributable to fluctuations caused by the dam were recorded. 53 refs., 24 figs., 35 tabs.

    Full Text Available Background: Low levels of circulating vitamin D are more likely to be found in those with darker skin pigmentation, who live in areas of high latitude, and who wear more clothing. We examined the prevalence of vitamin D deficiency and inadequacy in newcomer immigrant and refugee children. Methods: We evaluated circulating vitamin D status of immigrant children at the national level. Subsequently, we investigated vitamin D intake, circulating vitamin D status, and total body bone mineral content (TBBMC in newcomer children living in Saskatchewan. Results: In the sample of newcomer children in Saskatchewan, the prevalence of inadequacy in calcium and vitamin D intakes was 76% and 89.4%, respectively. Vitamin D intake from food/supplement was significantly higher in immigrants compared to refugees, which accords with the significant difference in serum status. Circulating vitamin D status indicated that 29% of participants were deficient and another 44% had inadequate levels of serum 25(OHD for bone health. Dietary vitamin D intake, sex, region of origin, and length of stay in Canada were significant predictors of serum vitamin D status. Results for TBBMC revealed that 38.6% were found to have low TBBMC compared to estimated values for age, sex, and ethnicity. In the regression model, after controlling for possible confounders, children who were taller and had greater circulating vitamin D also had greater TBBMC. Nationally, immigrant children, particularly girls, have significantly lower plasma 25(OHD than non-immigrant children. Interpretation: Newcomer immigrant and refugee children are at a high risk of vitamin D deficiency and inadequacy, which may have serious negative consequences for their health.

    Polar bears (Ursus maritimus) of the northern Beaufort Sea (NB) population occur on the perimeter of the polar basin adjacent to the northwestern islands of the Canadian Arctic Archipelago. Sea ice converges on the islands through most of the year. We used open-population capture–recapture models to estimate population size and vital rates of polar bears between 1971 and 2006 to: (1) assess relationships between survival, sex and age, and time period; (2) evaluate the long-term importance of sea ice quality and availability in relation to climate warming; and (3) note future management and conservation concerns. The highest-ranking models suggested that survival of polar bears varied by age class and with changes in the sea ice habitat. Model-averaged estimates of survival (which include harvest mortality) for senescent adults ranged from 0.37 to 0.62, from 0.22 to 0.68 for cubs of the year (COY) and yearlings, and from 0.77 to 0.92 for 2–4 year-olds and adults. Horvtiz-Thompson (HT) estimates of population size were not significantly different among the decades of our study. The population size estimated for the 2000s was 980 ± 155 (mean and 95% CI). These estimates apply primarily to that segment of the NB population residing west and south of Banks Island. The NB polar bear population appears to have been stable or possibly increasing slightly during the period of our study. This suggests that ice conditions have remained suitable and similar for feeding in summer and fall during most years and that the traditional and legal Inuvialuit harvest has not exceeded sustainable levels. However, the amount of ice remaining in the study area at the end of summer, and the proportion that continues to lie over the biologically productive continental shelf (polar bear population in the northern Beaufort Sea will eventually decline. Management and conservation practices for polar bears in relation to both aboriginal harvesting and offshore industrial activity will need

    Traditionally, the epidemiology of avian influenza viruses (AIVs) in wild birds has been defined by detection of virus or viral RNA through virus isolation or reverse-transcription polymerase chain reaction. Our goals were to estimate AIV antibody prevalence in Canada geese (Branta canadensis) and measure effects of age and location on these estimates. We collected 3,205 samples from nine states during June and July 2008 and 2009: Georgia, Massachusetts, Minnesota, Mississippi, New Jersey, North Carolina, Pennsylvania, Washington, and West Virginia. Serum samples were tested for AIV antibodies with the use of a commercial blocking enzyme-linked immunosorbent assay. Overall, 483 (15%) Canada geese had detectable antibodies to AIV. Significantly higher prevalences were detected in geese collected from northeastern and upper midwestern states compared with southeastern states. This trend is consistent with results from virus isolation studies reporting AIV prevalence in North American dabbling ducks. Within Pennsylvania, significantly higher antibody prevalences were detected in goose flocks sampled in urban locations compared to flocks sampled in rural areas. Antibody prevalence was significantly higher in after-hatch-year geese compared to hatch-year geese. No significant differences in prevalence were detected from 10 locations sampled during both years. Results indicate that Canada geese are frequently exposed to AIVs and, with resident populations, may potentially be useful as sentinels to confirm regional AIV transmission within wild bird populations.

    Until recently, the sea ice habitat of polar bears was understood to be variable, but environmental variability was considered to be cyclic or random, rather than progressive. Harvested populations were believed to be at levels where density effects were considered not significant. However, because we now understand that polar bear demography can also be influenced by progressive change in the environment, and some populations have increased to greater densities than historically lower numbers, a broader suite of factors should be considered in demographic studies and management. We analyzed 35 years of capture and harvest data from the polar bear (Ursus maritimus) subpopulation in Davis Strait, including data from a new study (2005–2007), to quantify its current demography. We estimated the population size in 2007 to be 2,158 ± 180 (SE), a likely increase from the 1970s. We detected variation in survival, reproductive rates, and age-structure of polar bears from geographic sub-regions. Survival and reproduction of bears in southern Davis Strait was greater than in the north and tied to a concurrent dramatic increase in breeding harp seals (Pagophilus groenlandicus) in Labrador. The most supported survival models contained geographic and temporal variables. Harp seal abundance was significantly related to polar bear survival. Our estimates of declining harvest recovery rate, and increasing total survival, suggest that the rate of harvest declined over time. Low recruitment rates, average adult survival rates, and high population density, in an environment of high prey density, but deteriorating and variable ice conditions, currently characterize the Davis Strait polar bears. Low reproductive rates may reflect negative effects of greater densities or worsening ice conditions.

    Full Text Available Objectives: To evaluate preterm birth (PTB for Inuit and First Nations vs. non-Indigenous populations in the province of Québec, Canada. Study design: Retrospective cohort study. Methods: We evaluated singleton live births for Québec residents, 1981–2008 (n = 2,310,466. Municipality of residence (Inuit-inhabited, First Nations-inhabited, rest of Québec and language (Inuit, First Nations, French/English were used to identify Inuit and First Nations births. The outcome was PTB (<37 completed weeks. Cox proportional hazards regression was employed to estimate hazard ratios (HR and 95% confidence intervals (CI of PTB, adjusting for maternal age, education, marital status, parity and birth year. Results: PTB rates were higher for Inuit language speakers in Inuit-inhabited areas and the rest of Québec compared with French/English speakers in the rest of Québec, and disparities persisted over time. Relative to French/English speakers in the rest of Québec, Inuit language speakers in the rest of Québec had the highest risk of PTB (HR 1.98, 95% CI: 1.62–2.41. The risk was also elevated for Inuit language speakers in Inuit-inhabited areas, though to a lesser extent (HR 1.29, 95% CI: 1.18–1.41. In contrast, First Nations language speakers in First Nations-inhabited areas and the rest of Québec had similar or lower risks of PTB relative to French/English speakers in the rest of Québec. Conclusions: Inuit populations, especially those outside Inuit-inhabited areas, have persistently elevated risks of PTB, indicating a need for strategies to prevent PTB in this population.

  15. An ephemeral sexual population of Phytophthora infestans in the Northeastern United States and Canada.

    Giovanna Danies

    Full Text Available Phytophthora infestans, the causal agent of late blight disease, has been reported in North America since the mid-nineteenth century. In the United States the lack of or very limited sexual reproduction has resulted in largely clonal populations of P. infestans. In 2010 and 2011, but not in 2012 or 2013, 20 rare and diverse genotypes of P. infestans were detected in a region that centered around central New York State. The ratio of A1 to A2 mating types among these genotypes was close to the 50∶50 ratio expected for sexual recombination. These genotypes were diverse at the glucose-6-phosphate isomerase locus, differed in their microsatellite profiles, showed different banding patterns in a restriction fragment length polymorphism assay using a moderately repetitive and highly polymorphic probe (RG57, were polymorphic for four different nuclear genes and differed in their sensitivity to the systemic fungicide mefenoxam. The null hypothesis of linkage equilibrium was not rejected, which suggests the population could be sexual. These new genotypes were monomorphic in their mitochondrial haplotype that was the same as US-22. Through parentage exclusion testing using microsatellite data and sequences of four nuclear genes, recent dominant lineages US-8, US-11, US-23, and US-24 were excluded as possible parents for these genotypes. Further analyses indicated that US-22 could not be eliminated as a possible parent for 14 of the 20 genotypes. We conclude that US-22 could be a parent of some, but not all, of the new genotypes found in 2010 and 2011. There were at least two other parents for this population and the genotypic characteristics of the other parents were identified.

  18. Breeding Status and Population Trends of Golden Eagles in Northeastern Québec, Canada

    Directory of Open Access Journals (Sweden)

    Junior A. Tremblay

    2012-12-01

    Full Text Available In North America, it is hypothesized that the Golden Eagle's (Aquila chrysaetos eastern population declined during the period 1946-1973 because of organochlorine pesticides and other anthropogenic causes of mortality. Since 1970, upward trends for the species have been observed at most eastern hawkwatches. To determine whether such positive trends can be observed on breeding grounds, Golden Eagle counts were performed to monitor nesting territory occupancy between 1994 and 2007 in the Moisie and Sainte-Marguerite River valleys, northeastern Québec. Aerial surveys were conducted during seven of the 14 years. During this period, the number of known nesting territories in the study area increased from 10 to 20, while the number of pairs rose from six to 14. The increase is attributed mostly to investigators' improved experience in finding nests and to their greater familiarity with the study area, and possibly to the growth of the regional population. Occupancy of nesting territories by pairs was very stable over the years. Annual mean % of laying pairs (or laying rate was 48.0 (SD = 19.9, and productivity (mean number of fledglings per pair was 0.49 (SD = 0.35.

    Perz, Johanna

    I used a GIS raster layer of an area in the Churchill, Manitoba region to investigate the effect of breeding habitat on demography and density of Whimbrel from 2010 through 2013. Program MARK was used to quantify adult and daily nest survival. Apparent annual survival of 0.73 +/- 0.06 SE (95% CI = 0.60-0.83) did not significantly differ between sexes or habitats and was lower than expected based on longevity records and estimates for other large-bodied shorebirds. Nest success, corrected for exposure days, was highly variable, ranging from a low of 3% (95% CI = 0-12%) in 2011 to a high of 71% (95% CI = 54-83%) in 2013. The highest rate of nest survival occurred in the spring with the warmest mean temperature. I developed a generalized linear model (GLM) with a negative-binomial distribution from random plots that were surveyed for abundance to extrapolate a local breeding population size of 410 +/- 230 SE and density of 3.2 birds per square km +/- 1.8 SE. The result of my study suggests that other aspects of habitat not captured by the land cover categories may be more important to population dynamics.

  20. Making Our Health and Care Systems Fit for an Ageing Population: Considerations for Canada

    2014-01-01

    A report from the United Kingdom on making health and care systems fit for an ageing population proposes a range of interventions to make care better for older adults, especially those who are frail. Here, we discuss the proposed shift for the acute care hospital to other models of care. The key for these models of care requires a fundamental shift to care that addresses the full range of an individual’s needs, rather than being based around single diseases. How this might apply in the Canadian context is considered. We emphasize strategies to keep people out of hospital but still receive needed care, make acute hospital care less hazardous, and improve the interface between acute and long-term care.

  1. Anal erogeneity: the goose and the rat.

    Science.gov (United States)

    Shengold, L

    1982-01-01

    A case is presented in which the patient's traumatically derived intense anal erogeneity (associated with traumatic anxiety as well as with castration anxiety) inhibited his phallic sensations and potency and also his power to sustain productive thought. His passive cravings were disguised and reacted against in his compulsive-exhibitionistically phallic role of a Don Juan. He described at least two levels of anal feelings: a dangerous but exciting, tolerable or even pleasurable tension associated with the imago of the goose; and an unbearable, terrifying overcharged level embodied in the imago of the rat. (He had read of, and had felt himself identified with, Freud's Rat Man.) Contrasts are presented with François Rabelais' account of the instinctual development and anal training of Gargantua, in which the connotations of the goose lead to a happy anal, phallic and intellectual control. Generalizations are ventured about the crucial attainment of command over the anal sphincter for the taming of 'primal affect'(Fliess). With early psychopathology there is a defensive overcathexis of anal control (and of anal mechanisms and character traits) to try to contain over-stimulation. In contrast true anal mastery contributes to the acquisition of optimal genital feelings and functioning and to the capacity for sustaining integrative thinking so necessary for 'owning' one's affects and impulses, and therefore for a feeling of identity. Finally, some remarks of Freud on Rabelais are reviewed in relation to levels of urethral erogeneity, seen as developmental way stations between the anal and the phallic, and partaking of both.

    We used data from the 1991-2006 Canadian Census Mortality and Cancer Follow-up Study to compare all-cause mortality for immigrants with that of the Canadian-born population. The study addressed two related questions. First, do immigrants have a mortality advantage over the Canadian-born? Second, if immigrants have a mortality advantage, does it persist as their duration of residence increases? The analysis fitted sex-stratified hazard regression models for the overall sample and for selected countries of birth (UK, China, India, Philippines, and the Caribbean). Predictors were assessed at baseline. Mortality was lower among immigrants than the Canadian-born even after adjusting for a selected group of socio-demographic and socio-economic factors. The mortality differences persisted even after long residence in Canada, but appeared to be dependent on the age of the individual and the country of origin. Interpreted in light of known explanations of immigrant mortality advantage, the results mostly reflect selection effects.

    High rates of substance use, especially cannabis and stimulant use, have been associated with homelessness, exposure to trauma, and involvement with the criminal justice system. This study explored differences in substance use (cannabis vs. stimulants) and associations with trauma and incarceration among a homeless population. Data were derived from the BC Health of the Homeless Study (BCHOHS), carried out in three cities in British Columbia, Canada. Measures included sociodemographic information, the Maudsley Addiction Profile (MAP), the Childhood Trauma Questionnaire (CTQ), and the Mini International Neuropsychiatric Interview (MINI) Plus. Stimulant users were more likely to be female (43%), using multiple substances (3.2), and engaging in survival sex (14%). Cannabis users had higher rates of lifetime psychotic disorders (32%). Among the incarcerated, cannabis users had been subjected to greater emotional neglect (p < .05) and one in two cannabis users had a history of lifetime depressive disorders (p < .05). Childhood physical abuse and Caucasian ethnicity were also associated with greater crack cocaine use. One explanation for the results is that a history of childhood abuse may lead to a developmental cascade of depressive symptoms and other psychopathology, increasing the chances of cannabis dependence and the development of psychosis.

    Full Text Available Abstract Background Asthma is a common yet incompletely understood health problem associated with a high morbidity burden. A wide variety of seasonally variable environmental stimuli such as viruses and air pollution are believed to influence asthma morbidity. This study set out to examine the seasonal patterns of asthma hospitalisations in relation to age and gender for the province of Ontario over a period of 12 years. Methods A retrospective, population-based study design was used to assess temporal patterns in hospitalisations for asthma from April 1, 1988 to March 31, 2000. Approximately 14 million residents of Ontario eligible for universal healthcare coverage during this time were included for analysis. Time series analyses were conducted on monthly aggregations of hospitalisations. Results There is strong evidence of an autumn peak and summer trough seasonal pattern occurring every year over the 12-year period (Fisher-Kappa (FK = 23.93, p > 0.01; Bartlett Kolmogorov Smirnov (BKS = 0.459, p Conclusions A clear and consistent seasonal pattern was observed in this study for asthma hospitalisations. These findings have important implications for the development of effective management and prevention strategies.

  5. Effects of Water Levels on Productivity of Canada Geese in the Northern Flathead Valley, 1985 Annual Report.

    Casey, Daniel

    1986-04-01

    Operation of Hungry Horse Dam on the South Fork Flathead River causes sporadic water level fluctuations along the main stem Flathead River. Changes in chronology of seasonal water level fluctuations and substantial habitat losses have occurred as a result of construction and operation of Kerr Dam, which regulates Flathead Lake. These fluctuations may impact goose populations through flooding and erosion of nesting and brood-rearing habitats, and increased susceptibility of nests and young to predation. The number, location, and success of goose nests were determined through pair surveys and nest searches. Our 1985 pair count data indicated that 95 to 143 nests may have been present. Hatching success for 1985 nests (55%) was low compared to long-term averages for the region. Predation was the predominant cause of ground nest failure (25 nests); we documented 2 nest failures due to flooding. The maximum gosling count in the study area for 1985 was 197. Six key brood-rearing areas were identified. Most (80%) sites were located in the herbaceous or pasture cover type and the riparian bench landform. Analysis of aerial photographs taken prior to construction of Kerr Dam documented the loss of 1859 acres of habitat along the north shore of Flathead Lake. Losses were attributed to inundation and to continuing erosion due to operation of Kerr Dam. Lake and river water level regimes were compared with the chronology of important periods in the nesting cycle. Low lake levels in May and early June coincide with the breed-rearing period. Mudflats are heavily used by broods, but their effect on survival must still be documented. Preliminary recommendations to protect and enhance Canada goose habitat and production are being developed.

    Full Text Available Non-invasive measures for assessing long-term stress in free ranging mammals are an increasingly important approach for understanding physiological responses to landscape conditions. Using a spatially and temporally expansive dataset of hair cortisol concentrations (HCC generated from a threatened grizzly bear (Ursus arctos population in Alberta, Canada, we quantified how variables representing habitat conditions and anthropogenic disturbance impact long-term stress in grizzly bears. We characterized spatial variability in male and female HCC point data using kernel density estimation and quantified variable influence on spatial patterns of male and female HCC stress surfaces using random forests. Separate models were developed for regions inside and outside of parks and protected areas to account for substantial differences in anthropogenic activity and disturbance within the study area. Variance explained in the random forest models ranged from 55.34% to 74.96% for males and 58.15% to 68.46% for females. Predicted HCC levels were higher for females compared to males. Generally, high spatially continuous female HCC levels were associated with parks and protected areas while low-to-moderate levels were associated with increased anthropogenic disturbance. In contrast, male HCC levels were low in parks and protected areas and low-to-moderate in areas with increased anthropogenic disturbance. Spatial variability in gender-specific HCC levels reveal that the type and intensity of external stressors are not uniform across the landscape and that male and female grizzly bears may be exposed to, or perceive, potential stressors differently. We suggest observed spatial patterns of long-term stress may be the result of the availability and distribution of foods related to disturbance features, potential sexual segregation in available habitat selection, and may not be influenced by sources of mortality which represent acute traumas.

    Immunoglobulins play an important role in adaptive immune system as defense molecules against pathogens. However, our knowledge on avian immunoglobulin genes has been limited to a few species. In this study, we analyzed goose (Anser cygnoides orientalis) immunoglobulin genes. Three IgH classes including IgM, IgA, IgY and λ light chain were identified. The IgM and IgA heavy chain constant regions are characteristically similar to their counterparts described in other vertebrates. In addition to the classic Ig isotypes, we also detected a transcript that encoded a truncated form of IgY (IgY(ΔFc)) in goose. Similar to duck, the IgY(ΔFc) in goose was generated by using different transcriptional termination signal of the same υ gene. Limited variability and only one leader peptide were observed in VH and VL domains, which suggested that gene conversion was the primary mechanism involved in goose antibody diversity. Our study provides more insights into the immunoglobulin genes in goose that had not been fully explored before.

    Avian bornaviruses (ABV), identified in 2008, infect captive parrots and macaws worldwide. The natural reservoirs of these viruses are unknown. Reverse transcription-PCR (RT-PCR) was used to screen oropharyngeal/cloacal swab and brain samples from wild Canada geese (Branta canadensis) for ABV. Approximately 2.9% of swab samples were positive for bornavirus sequences. Fifty-two percent of brain samples from 2 urban flocks also tested positive, and brain isolates were cultured in duck embryo fibroblasts. Phylogenetic analyses placed goose isolates in an independent cluster, and more notably, important regulatory sequences present in Borna disease virus but lacking in psittacine ABVs were present in goose isolates.

  16. Benzodiazepine Use, Misuse, and Harm at the Population Level in Canada: A Comprehensive Narrative Review of Data and Developments Since 1995.

    2016-07-01

    Benzodiazepines are commonly prescribed psycho-pharmaceuticals (e.g., for anxiety, tension, and insomnia); they are generally considered safe but have potential adverse effects. Benzodiazepine use in Canada versus internationally is comparably high, yet no recent comprehensive review of use, misuse, or related (e.g., morbidity, mortality) harm at the population level exists; the present review aimed to fill this gap. We searched four key scientific literature databases (Medline, CINAHL, EBM Reviews, and Web of Science) with relevant search terms, and collected relevant "gray literature" (e.g., survey, monitoring, government reports) data published in 1995-2015. Two reviewers conducted data screening and extraction; results were categorized and narratively summarized by key sub-topics. Levels of benzodiazepine use in the general population have been relatively stable in recent years; medical use is generally highest among older adults. Rates of non-medical use are fairly low in general but higher in marginalized (e.g., street drug use) populations; high and/or inappropriate prescribing appears common in older adults. Benzodiazepines are associated with various morbidity outcomes (e.g., accidents/injuries, cognitive decline, sleep disturbances, or psychiatric issues), again commonly observed in older adults; moreover, benzodiazepines are identified as a contributing factor in suicides and poisoning deaths. Overall there is a substantial benzodiazepine-related health problem burden-although lower than that for other psycho-medications (e.g., opioids)-in Canada, mainly as a result of overuse and/or morbidity. National benzodiazepine prescription guidelines are lacking, and few evaluated interventions to reduce benzodiazepine-related problems exist. There is a clear need for reducing inappropriate benzodiazepine use and related harm in Canada through improved evidence-based practice as well as monitoring and control. PMID:27056579

  20. Canadian population risk of radon induced lung cancer: A re-assessment based on the recent cross-Canada radon survey

    International Nuclear Information System (INIS)

    Exposure to indoor radon has been determined to be the second leading cause of lung cancer after tobacco smoking. Canadian population risk of radon induced lung cancer was assessed in 2005 with the radon distribution characteristics determined from a radon survey carried out in the late 1970's in 19 cities. In that survey, a grab sampling method was used to measure radon levels. The observed radon concentration in 14 000 Canadian homes surveyed followed a log-normal distribution with a geometric mean (GM) of 11.2 Bq m-3 and a geometric standard deviation (GSD) of 3.9. Based on the information from that survey, it was estimated that ∼10 % of lung cancers in Canada resulted from indoor radon exposure. To gain a better understanding of radon concentrations in homes across the country, a national residential radon survey was launched in April 2009. In the recent survey, long-term (3 month or longer) indoor radon measurements were made in roughly 14 000 homes in 121 health regions across Canada. The observed radon concentrations follow, as expected, a log-normal distribution with a GM of 41.9 Bq m-3 and a GSD of 2.8. Based on the more accurate radon distribution characteristics obtained from the recent cross-Canada radon survey, a re-assessment of Canadian population risk for radon induced lung cancer was undertaken. The theoretical estimates show that 16 % of lung cancer deaths among Canadians are attributable to indoor radon exposure. These results strongly suggest the ongoing need for the Canadian National Radon Program. In particular, there is a need for a focus on education and awareness by all levels of government, and in partnership with key stakeholders, to encourage Canadians to take action to reduce the risk from indoor radon exposure.

    Full Text Available In central Canada, long fire history reconstructions are rare. In a context where both anthropogenic and climate influences on fire regime have changed, Parks Canada has a mandate to maintain ecological integrity. Here we present a fire history derived from fire-scarred jack pine (Pinus banksiana Lamb. trees growing at their southern distribution limit in Riding Mountain National Park (RMNP. In Lake Katherine Fire Management Unit (LKFMU, a subregion within the park, fire history was reconstructed from archival records, tree-ring records, and charcoal in lake sediment. From about 1450 to 1850 common era (CE the fire return intervals varied from 37 to 125 years, according to models. During the period 1864–1930 the study area burned frequently (Weibull Mean Fire Intervals between 2.66 and 5.62 years; this period coincided with the end of First Nations occupation and the start of European settlement. Major recruitment pulses were associated with the stand-replacing 1864 and 1894 fires. This period nevertheless corresponded to a reduction in charcoal accumulation. The current fire-free period in LKFMU (1930–today coincides with RMNP establishment, exclusion of First Nations land use and increased fire suppression. Charcoal accumulation further decreased during this period. In the absence of fire, jack pine exclusion in LKFMU is foreseeable and the use of prescribed burning is advocated to conserve this protected jack pine ecosystem, at the southern margins of its range, and in the face of potential climate change.

    The aim of this work was to determine the microorganisms present and to investigate their metabolites that cause spoilage of many goose sausages produced in Friuli, a northeast region of Italy. The defect was observed by sensorial analysis using the "needle probing" technique; the spoiled sausages were unsafe and not marketable. Despite the addition of starter, the microorganisms, particularly enterococci and Enterobacteriaceae, grew during ripening and produced a large amount of biogenic amines; therefore, these sausages represented a risk to consumers. The production of those compounds was confirmed in vitro. Furthermore, a second cause of spoilage was attributed to moulds that grew during ripening; the fungi grew between the meat and casing, producing a large amount of total volatile nitrogen, and consequently an ammonia smell was present either in the ripening area or in the sausages. This is the first description of this type of defect in goose sausages. PMID:27217359

  5. Testing the environmental Kuznets curve hypothesis with bird populations as habitat-specific environmental indicators: evidence from Canada.

    Science.gov (United States)

    Lantz, Van; Martínez-Espiñeira, Roberto

    2008-04-01

    The traditional environmental Kuznets curve (EKC) hypothesis postulates that environmental degradation follows an inverted U-shaped relationship with gross domestic product (GDP) per capita. We tested the EKC hypothesis with bird populations in 5 different habitats as environmental quality indicators. Because birds are considered environmental goods, for them the EKC hypothesis would instead be associated with a U-shaped relationship between bird populations and GDP per capita. In keeping with the literature, we included other variables in the analysis-namely, human population density and time index variables (the latter variable captured the impact of persistent and exogenous climate and/or policy changes on bird populations over time). Using data from 9 Canadian provinces gathered over 37 years, we used a generalized least-squares regression for each bird habitat type, which accounted for the panel structure of the data, the cross-sectional dependence across provinces in the residuals, heteroskedasticity, and fixed- or random-effect specifications of the models. We found evidence that supports the EKC hypothesis for 3 of the 5 bird population habitat types. In addition, the relationship between human population density and the different bird populations varied, which emphasizes the complex nature of the impact that human populations have on the environment. The relationship between the time-index variable and the different bird populations also varied, which indicates there are other persistent and significant influences on bird populations over time. Overall our EKC results were consistent with those found for threatened bird species, indicating that economic prosperity does indeed act to benefit some bird populations.

  6. Spatial patterns of goose grubbing suggest elevated grubbing in dry habitats linked to early snowmelt

    Directory of Open Access Journals (Sweden)

    Åshild Ø. Pedersen

    2013-05-01

    Full Text Available The western Palaearctic tundra is a breeding habitat for large populations of European geese. After their arrival in spring, pink-footed geese (Anser brachyrhynchus forage extensively on below-ground plant parts, using a feeding technique called grubbing that has substantial impact on the tundra vegetation. Previous studies have shown a high frequency of grubbing in lowland fen vegetation. In the present study, we examined the occurrence of grubbing in other habitat types on Spitsbergen, in the Arctic archipelago of Svalbard. Goose grubbing was surveyed along 19 altitudinal transects, going from the valley bottom to altitudes dominated by scree. Grubbing was more frequent in the wet habitat type at low altitudes compared to the drier habitat type at higher altitudes. For the dry habitat type, a higher frequency of grubbing was found in study plots with a south-east facing exposure where snowmelt is expected to be early. This suggests that pink-footed geese primarily use dry vegetation types for grubbing when they are snow-free in early spring and the availability of snow-free patches of the preferred wet vegetation types in the lowlands is limited. Dry vegetation types have poorer recovery rates from disturbance than wet ones. Sites with early snowmelt and dry vegetation types may therefore be at greater risk of long-term habitat degradation. We conclude that the high growth rate of the Svalbard-breeding pink-footed goose population suggests that increasing impacts of grubbing can be expected and argue that a responsible monitoring of the effects on the tundra ecosystem is crucial.

  8. Decision-support model to explore the feasibility of using translocation to restore a woodland caribou population in Pukaskwa National Park, Canada

    Directory of Open Access Journals (Sweden)

    Emily K. Gonzales

    2015-12-01

    Full Text Available The distribution and abundance of woodland caribou (Rangifer tarandus caribou have declined dramatically in the past century. Without intervention the most southern population of caribou in eastern North America is expected to disappear within 20 years. Although translocations have reintroduced and reinforced some populations, approximately half of caribou translocation efforts fail. Translocations are resource intensive and risky, and multiple interrelated factors must be considered to assess their potential for success. Structured decision-making tools, such as Bayesian belief networks, provide objective methods to assess different wildlife management scenarios by identifying the key components and relationships in an ecosystem. They can also catalyze dialogue with stakeholders and provide a record of the complex thought processes used in reaching a decision. We developed a Bayesian belief network for a proposed translocation of woodland caribou into a national park on the northeastern coast of Lake Superior, Ontario, Canada. We tested scenarios with favourable (e.g., good physical condition of adult caribou and unfavourable (e.g., high predator densities conditions with low, medium, and high numbers of translocated caribou. Under the current conditions at Pukaskwa National Park, augmenting the caribou population is unlikely to recover the species unless wolf densities remain low (<5.5/1000 km2 or if more than 300 animals could be translocated.

  9. Estimating the mercury exposure dose in a population of migratory bird hunters in the St. Lawrence River region, Quebec, Canada

    International Nuclear Information System (INIS)

    St. Lawrence River hunters (Quebec, Canada) are exposed to the pollutants, especially mercury, that contaminate birds and fish. However, the health risks of this have remained unclear because of a lack of information about the hunters' duck, geese, and sportfish consumption habits. A nutritional survey was set up to characterize waterfowl and sportfish consumption in St. Lawrence River duck hunters and to estimate their daily exposure to mercury. During the winter of 2000, 512 hunters selected from the Canadian Wildlife Service database completed a self-administered questionnaire. Daily exposure to contaminants was measured using data from the Canadian Wildlife Service (waterfowl) and available data on St. Lawrence River sportfish. The annual average consumption was 7.5 meals of ducks and geese and 8.7 meals of sportfish. The daily exposure to mercury related to waterfowl consumption was below the Canadian tolerable daily intake (TDI) of 0.47 μg/kg body wt/day for all participants. The daily mercury intake associated with fish consumption was greater than the TDI in 2 duck hunters. The daily exposure to mercury was higher than the TDI in 4 participants when both waterfowl and fish consumption were combined. Our results suggest that fish consumption (especially freshwater fish) represents the main source of exposure to pollutants in duck hunters

    2010-01-01

    Full Text Available MHC class I proteins mediate functions in anti-pathogen defense. MHC diversity has already been investigated by many studies in model avian species, but here we chose the bar-headed goose, a worldwide migrant bird, as a non-model avian species. Sequences from exons encoding the peptide-binding region (PBR of MHC class I molecules were isolated from liver genomic DNA, to investigate variation in these genes. These are the first MHC class I partial sequences of the bar-headed goose to be reported. A preliminary analysis suggests the presence of at least four MHC class I genes, which share great similarity with those of the goose and duck. A phylogenetic analysis of bar-headed goose, goose and duck MHC class I sequences using the NJ method supports the idea that they all cluster within the anseriforms clade.

  11. Spring snow goose hunting influences body composition of waterfowl staging in Nebraska

    2012-01-01

    A spring hunt was instituted in North America to reduce abundance of snow geese (Chen caerulescens) by increasing mortality of adults directly, yet disturbance from hunting activities can indirectly influence body condition and ultimately, reproductive success. We estimated effects of hunting disturbance by comparing body composition of snow geese and non-target species, greater white-fronted geese (Anser albifrons) and northern pintails (Anas acuta) collected in portions of south-central Nebraska that were open (eastern Rainwater Basin, ERB) and closed (western Rainwater Basin, WRB; and central Platte River Valley, CPRV) to snow goose hunting during springs 1998 and 1999. Lipid content of 170 snow geese was 25% (57 g) less in areas open to hunting compared to areas closed during hunting season but similar in all areas after hunting was concluded in the ERB. Protein content of snow geese was 3% (14 g) less in the region open to hunting. Greater white-fronted geese had 24% (76 g; n = 129) less lipids in the hunted portion of the study area during hunting season, and this difference persisted after conclusion of hunting season. We found little difference in lipid or protein content of northern pintails in relation to spring hunting. Indirect effects of spring hunting may be considered a collateral benefit regarding efforts to reduce overabundant snow goose populations. Disrupted nutrient storage observed in greater white-fronted geese represents an unintended consequence of spring hunting that has potential to adversely affect reproduction for this and other species of waterbirds staging in the region.

    A multi-disciplinary approach was used to evaluate the health of yellow perch (Perca flavescens) in the St. Lawrence River (Quebec, Canada), which is experiencing a severe population decline in the downstream portion of the river. Physiological parameters, liver alterations, trace metal concentrations, parasite prevalence and abundance, stable isotope composition, and the presence/absence of the viral hemorragic septicemia virus (VHSV) were evaluated in perch collected at six sites along the river: Lake St. François, Lake St. Louis (north and south), Beauregard Island, and Lake St. Pierre (north and south). Trace metal concentrations in surface water were higher in Lake St. Louis and downstream of a major urban wastewater treatment plant discharge, indicating that this effluent was a significant source of Cu, As, Ag, Zn, and Cd. Levels of Pb in surface water exceeded thresholds for the protection of aquatic life in Lake St. Louis and were negatively correlated with body condition index in this lake. In Lake St. Pierre, Cu, Ag, and Cd bioaccumulated significantly in perch liver and lower body condition index and greater liver damage were observed compared to upstream sites. Parasite analyses indicated a higher abundance of metacercariae of the trematodes Apophallus brevis and Diplostomum spp. in Lake St. Louis, and VHSV was not detected in the liver of yellow perch for all studied sites. Overall, results suggested that the global health of yellow perch from Lake St. Pierre is lower compared to upstream studied sites, which could contribute to the documented population collapse at this site.

Methods A telephone survey (n = 2,545 of adults living in the southern part of the province of Québec (Canada was conducted in the early fall season of 2005. The questionnaire used closed questions and measured the respondents' beliefs and current adaptations about CC. Calibration weighting was used to adjust the data analysis for the respondent's age and language under stratified sampling based on health regions. Results More than three out of four respondents had access to a single source of energy at home, which was mainly electricity; 22.2% combined two sources or more; 18.5% heated with wood occasionally or daily during the winter. The prevalence of wood heating was higher in the peripheral regions than in the more urban regions, where there was a higher proportion of respondents living in apartments. The prevalence was also higher with participants completely disagreeing (38.5% with the eventual prohibition of wood heating when there is smog in winter, compared to respondents somewhat disagreeing (24.2% or agreeing (somewhat: 17.5%; completely: 10.4% with the adoption of this strategy. It appears that the perception of living in a region susceptible to winter smog, smog warnings in the media, or the belief in the human contribution to CC, did not influence significantly wood heating practices. Conclusion Increased residential wood heating could very well become a maladaptation to climate change, given its known consequences on winter smog and respiratory health. It would thus be appropriate to implement a long-term national program on improved and controlled residential wood

    A research study was conducted to determine public opinion in Alberta, a Canadian province, on the controversial topic of death hastening. Questions on the right to hastened death, end-of-life plans and end-of-life experiences were included in the Population Research Laboratory's annual 2010 health-care telephone survey, with 1203 adults providing results relatively representative of Albertans. Of all 1203, 72.6% said yes to the question: 'Should dying adults be able to request and get help from others to end their life early, in other words, this is a request for assisted suicide'? Among all who provided an answer, 36.8% indicated 'yes, every competent adult should have this right' and 40.6% indicated 'yes, but it should be allowed only in certain cases or situations'. Over 50% of respondents in all but one socio-demographic population sub-group (Religious-other) were supportive of the right to hastened death. However, multinomial regression analysis revealed that the experiences of deciding to euthanise a pet/animal and developing or planning to develop an advance directive predicted support, while self-reported religiosity predicted non-support. Finding majority public support for death hastening suggests that legalisation could potentially occur in the future; but with this policy first requiring a careful consideration of the model of assisted suicide or euthanasia that best protects people who are highly vulnerable to despair and suffering near the end of life.

    Full Text Available Choline is an essential nutrient and betaine is an osmolyte and methyl donor. Both are important to maintain health including adequate lipid metabolism. Supplementation of dietary choline and betaine increase muscle mass and reduce body fat in animals. However, little data is available regarding the role of dietary choline and betaine on body composition in humans.To investigate the association between dietary choline and betaine intakes with body composition in a large population based cross-sectional study.A total of 3214 subjects from the CODING (Complex Disease in Newfoundland population: Environment and Genetics study were assessed. Dietary choline and betaine intakes were computed from the Willett Food Frequency questionnaire. Body composition was measured using dual-energy X-ray absorptiometry following a 12-hour fast. Major confounding factors including age, sex, total calorie intake and physical activity level were controlled in all analyses.Significantly inverse correlations were found between dietary choline and betaine intakes, with all obesity measurements: total percent body fat (%BF, percent trunk fat (%TF, percent android fat (%AF, percent gynoid fat (%GF and anthropometrics: weight, body mass index, waist circumference, waist-to-hip ratio in both women and men (r range from -0.13 to -0.47 for choline and -0.09 to -0.26 for betaine, p<0.001 for all. Dietary choline intake had stronger association than betaine. Moreover, obese subjects had the lowest dietary choline and betaine intakes, with overweight subjects in the middle, and normal weight subjects consumed the highest dietary choline and betaine (p<0.001. Vice versa, when subjects were ranked according to dietary choline and betaine intakes, subjects with the highest intake of both had the lowest %TF, %AF, %GF, %BF and highest %LM among the groups in both sexes.Our findings indicate that high dietary choline and betaine intakes are significantly associated with favorable body

  17. Wild mallards have more "goose-like" bills than their ancestors: a case of anthropogenic influence?

    Directory of Open Access Journals (Sweden)

    Pär Söderquist

    Full Text Available Wild populations of the world's most common dabbling duck, the mallard (Anas platyrhynchos, run the risk of genetic introgression by farmed conspecifics released for hunting purposes. We tested whether bill morphology of free-living birds has changed since large-scale releases of farmed mallards started. Three groups of mallards from Sweden, Norway and Finland were compared: historical wild (before large-scale releases started, present-day wild, and present-day farmed. Higher density of bill lamellae was observed in historical wild mallards (only males. Farmed mallards had wider bills than present-day and historical wild ones. Present-day wild and farmed mallards also had higher and shorter bills than historical wild mallards. Present-day mallards thus tend to have more "goose-like" bills (wider, higher, and shorter than their ancestors. Our study suggests that surviving released mallards affect morphological traits in wild population by introgression. We discuss how such anthropogenic impact may lead to a maladapted and genetically compromised wild mallard population. Our study system has bearing on other taxa where large-scale releases of conspecifics with 'alien genes' may cause a cryptic invasive process that nevertheless has fitness consequences for individual birds.

  18. What is the comparative health status and associated risk factors for the Métis? A population-based study in Manitoba, Canada

    2011-10-01

    Full Text Available Abstract Background Métis are descendants of early 17th century relationships between North American Indians and Europeans. This study's objectives were: (1 to compare the health status of the Métis people to all other residents of Manitoba, Canada; and (2 to analyze factors in predicting the likelihood of diabetes and related lower limb amputation. Methods Using de-identified administrative databases plus the Métis Population Database housed at the Manitoba Centre for Health Policy, age/sex-adjusted rates of mortality and disease were calculated for Métis (n = 73,016 and all other Manitobans (n = 1,104,672. Diseases included: hypertension, arthritis, diabetes, ischemic heart disease (age 19+; osteoporosis (age 50+; acute myocardial infarction (AMI and stroke (age 40+; total respiratory morbidity (TRM, all ages. Using logistic regression, predictors of diabetes (2004/05-2006/07 and diabetes-related lower-limb amputations (2002/03-2006/07 were analyzed. Results Disease rates were higher for Métis compared to all others: premature mortality before age 75 (4.0 vs. 3.3 per 1000, p Conclusion Despite universal healthcare, Métis' illness and mortality rates are mostly higher. Although elevated diabetes risk persists for the Métis even after adjusting for sociodemographic, healthcare and comorbidity variables, the risk of amputation for Métis appears more related to healthcare access rather than ethnicity.

  6. Use of a Remote Car Starter in Relation to Smog and Climate Change Perceptions: A Population Survey in Québec (Canada

    Directory of Open Access Journals (Sweden)

    Belkacem Abdous

    2009-02-01

    Full Text Available Remote car starters encourage motorists to warm up their vehicles by idling the motor – thus increasing atmospheric pollutants, including several greenhouse gas (GHG with impacts on public health. This study about climate change (CC adaptation and mitigation actions examined perceptions on air pollution and climate change and individual characteristics associated with the use of a remote car starter. A telephone survey (n = 2,570; response rate: 70% of adults living in Québec (Canada measured the respondents’ beliefs and current behaviours regarding CC. Approximately 32.9% (daily car users and 27.4% (occasional users reported using a remote car starter during winter. The odds of the use of a remote car starter was higher in the less densely populated central (OR: 1.5 and peripheral regions (OR: 2.7 compared to the urban centers (ex. Montreal. The odds was also higher in population with a mother tongue other than English or French (OR: 2.6 and francophones than anglophones (OR: 2.1, women than men (OR: 1.5, daily drivers than occasional ones (OR: 1.2, and respondents who at least sometimes consulted temperature/humidity reports than those who consulted them less often (OR: 1.5. In multivariate analysis, the perception of living in a region susceptible to winter smog, being aware of smog warnings, or the belief in the human contribution to CC did not significantly influence the use of a remote car starter. The use of remote car starters encourages idling which produces increased atmospheric pollution and GHG production and it should be more efficiently and vigorously managed by various activities. A five-minute daily reduction in idling is equivalent to reducing the total car emissions by 1.8%. This would constitute a “no-regrets” approach to CC as it can simultaneously reduce GHG, air pollution and their health impacts.

    Full Text Available There is a high and rising rate of immune-mediated diseases in the Western world. Immigrants from South Asia have been reported to be at higher risk upon arrival to the West. We determined the risk of immune-mediated diseases in South Asian and other immigrants to Ontario, Canada, and their Ontario-born children.Population-based cohorts of patients with asthma, type 1 diabetes (T1DM, type 2 diabetes (T2DM, and inflammatory bowel disease (IBD were derived from health administrative data. We determined the standardized incidence, and the adjusted risk of these diseases in immigrants from South Asia, immigrants from other regions, compared with non-immigrant residents of Ontario. The risk of these diseases in the Ontario-born children of immigrants were compared to the children of non-immigrants.Compared to non-immigrants, adults from South Asia had higher risk of asthma (IRR 1.56, 95%CI 1.51-1.61 and T2DM (IRR 2.59, 95%CI 2.53-2.65. Adults from South Asia had lower incidence of IBD than non-immigrants (IRR 0.32, 95%CI 0.22-0.49, as did immigrants from other regions (IRR 0.29, 95%CI 0.20-0.42. Compared to non-immigrant children, the incidence of asthma (IRR 0.66, 95%CI 0.62-0.71 and IBD (IRR 0.47, 95%CI 0.33-0.67 was low amongst immigrant children from South Asia. However, the risk in Ontario-born children of South Asian immigrants relative to the children of non-immigrants was higher for asthma (IRR 1.75, 95%CI 1.69-1.81 and less attenuated for IBD (IRR 0.90, 95%CI 0.65-1.22.Early-life environmental exposures may trigger a genetic predisposition to the development of asthma and IBD in South Asian immigrants and their Canada-born children.

    Rates of mammography screening for breast cancer are disproportionately low in certain subgroups including low-income and immigrant women. The purpose of the study was to examine differences in rates of appropriate breast cancer screening (i.e., screening mammography every 2 years) among Ontario immigrant women by world region of origin and explore the association between appropriate breast cancer screening among these women groups and individual and structural factors. A cohort of 183,332 screening-eligible immigrant women living in Ontario between 2010 and 2012 was created from linked databases and classified into eight world regions of origin. Appropriate screening rates were calculated for each region by age group and selected sociodemographic, immigration, and healthcare-related characteristics. The association between appropriate screening across the eight regions of origin and selected sociodemographic, immigration, and health-related characteristics was explored using multivariate Poisson regression. Screening varied by region of origin, with South Asian women (48.5%) having the lowest and Caribbean and Latin American women (63.7%) the highest cancer screening rates. Factors significantly associated with lower screening across the world regions of origin included living in the lowest income neighborhoods, having a refugee status, being a new immigrant, not having a regular physical examination, not being enrolled in a primary care patient enrollment model, having a male physician, and having an internationally trained physician. Multiple interventions entailing cross-sector collaboration, promotion of patient enrollment models, community engagement, comprehensive and intensive outreach to women, and knowledge translation and transfer to physicians should be considered to address screening disparities among immigrant population. Consideration should be given to design and delivery of culturally appropriate and easily accessible cancer screening programs

  12. Trends in asthma-related direct medical costs from 2002 to 2007 in British Columbia, Canada: a population based-cohort study.

    Directory of Open Access Journals (Sweden)

    Pierrick Bedouch

    Full Text Available BACKGROUND: Asthma-related health resource use and costs may be influenced by increasing asthma prevalence, changes to asthma management guidelines, and new medications over the last decade. The objective of this work was to analyze direct asthma-related medical costs, and trends in total and per-patient costs of hospitalizations, physician visits, and medications. METHODS: A cohort of asthma patients from British Columbia (BC, Canada, was created. Asthma patients were identified using a validated case definition. Costs for hospitalizations, physician visits, and medications were calculated from billing records (in 2008 Canadian dollars. Trends in total and per-patient costs over the study period were analyzed using Generalized Linear Models. RESULTS: 398,235 patients satisfied the asthma case definition (mid-point prevalence 8.0%. Patients consumed $315.9 million (M in direct asthma-related health resources between 2002 and 2007. Hospitalizations, physician visits, and medication costs accounted for 16.0%, 15.7% and 68.2% of total costs, respectively. Cost of asthma increased from $49.4 M in 2002 to $54.7 M in 2007. Total annual costs attributable to hospitalizations and physician visits decreased (-39.8% and -25.5%, respectively; p<0.001, while medication costs increased (+38.7%; p<0.001. INTERPRETATION: This population-based analysis shows that the total direct cost of asthma in BC has increased since 2002, mainly due to a rise in asthma prevalence and cost of medication. Combination therapy with inhaled corticosteroids/long-acting beta-agonists has become a significant component of the cost of asthma. Although billing records capture only a fraction of the true burden of asthma, the simultaneous increase in medication costs and reductions in hospitalization and physician visit costs provides valuable insight for policy makers into the shifts in asthma-related resource use.

    Emerald ash borer is an invasive species from Asia. Beauveria bassiana strain L49-1AA is being tested for the control of emerald ash borer in Canada, using an autocontamination trapping system. We have developed a simplified allele discrimination polymerase chain reaction (PCR) assay to screen B. bassiana strain, L49-1AA from other Beauveria species by targeting the inter-strain genetic differences in 5' end of EF1-α gene of the genus Beauveria. A single nucleotide polymorphism (SNP) site, T→C was identified only in L49-1AA and was used to develop a simplified allele discrimination polymerase chain reaction (PCR) assay based on a modified allelic inhibition of displacement activity (AIDA) approach for distinguishing B. bassiana L49-1AA from all background Beauveria isolates. The SNP site was employed to design inner primers but with a deliberate mismatch introduced at the 3' antepenultimate from the mutation site in order to maximize specificity and detection efficiency. Amplification was specific to L49-1AA without cross-reaction with DNA from other Beauveria strains. In addition, the designed primers were also tested against environmental samples in L49-1AA released plots and observed to be highly efficient in detecting and discriminating the target strain, L49-1AA from both pure and crude DNA samples. This new method can potentially allow for more discriminatory tracking and monitoring of released L49-1AA in our autocontamination and dissemination projects for managing EAB populations. Additionally, the modified-AIDA format has potential as a tool for simultaneously identifying and differentiating closely related Beauveria species, strains/isolates as well as general classification of other pathogens or organisms.

    The lower Flathead System Canada Goose Study was initiated to determine population trends and the effects of water level fluctuations on nest and brood habitat on the southern half of Flathead Lake and the lower Flathead River as a result of the operations of Kerr Dam. This report presents data collected during the 1984 field season as part of an ongoing project. Geese used Pablo, Kicking Horse, Ninepipe Reservoirs heavily during late summer and fall. Use of the river by geese was high during the winter, when the reservoirs were frozen, and during the breeding period. Most breeding geese left the river after broods fledged. Thirteen percent of the artificial tree nest structures on the river were used by nesting geese. Goose nest initiation on the river peaked the last week in March through the first week in April, and hatching peaked the first week in May. Predation was the most significant cause of nest loss on the river, and nest loss by flooding was not observed. Avian predation was the single largest factor contributing to nest loss on the lake. Habitat use was studied in 4 brood areas on the river and 8 brood areas on the lake, and available habitat was assessed for 2 portions of both the lake and the river. Brood habitat use was significantly different from the available habitat in all areas studied. On the lower river, broods used wheat fields, gravel bars, and shrub habitats. On the upper river, coniferous forest and shrub habitats were preferred. On the West Bay of the lake, brood areas consisted primarily of lawns and tall herbaceous habitat, while on the South Bay, marshes dominated the brood areas studied. Water levels on the river and lake affect both accessibility of these areas to brooding geese, and the ecology of the habitats preferred by geese. 43 refs., 24 figs., 31 tabs.

  20. Individual-area relationship best explains goose species density in wetlands.

    Directory of Open Access Journals (Sweden)

    Yong Zhang

    Full Text Available Explaining and predicting animal distributions is one of the fundamental objectives in ecology and conservation biology. Animal habitat selection can be regulated by top-down and bottom-up processes, and is mediated by species interactions. Species varying in body size respond differently to top-down and bottom-up determinants, and hence understanding these allometric responses to those determinants is important for conservation. In this study, using two differently sized goose species wintering in the Yangtze floodplain, we tested the predictions derived from three different hypotheses (individual-area relationship, food resource and disturbance hypothesis to explain the spatial and temporal variation in densities of two goose species. Using Generalized Linear Mixed Models with a Markov Chain Monte Carlo technique, we demonstrated that goose density was positive correlated with patch area size, suggesting that the individual area-relationship best predicts differences in goose densities. Moreover, the other predictions, related to food availability and disturbance, were not significant. Buffalo grazing probably facilitated greater white-fronted geese, as the number of buffalos was positively correlated to the density of this species. We concluded that patch area size is the most important factor determining the density of goose species in our study area. Patch area size is directly determined by water levels in the Yangtze floodplain, and hence modifying the hydrological regimes can enlarge the capacity of these wetlands for migratory birds.

    A real-time quantitative Polymerase Chain Reaction (PCR) method has been developed for the quantitation of mule duck (Anas platyrhynchos x Cairina moschata) in binary duck/goose foie gras mixtures. The method combines the use of real-time PCR with duck-specific and endogenous control "duck + goose" primers to measure duck content and total foie gras content, respectively. Both PCR systems (duck-specific and duck + goose) were designed on the mitochondrial 12S ribosomal RNA gene (rRNA). The duck-specific system amplifies a 96 bp fragment from duck DNA, whereas the duck + goose system amplifies a 120 bp fragment from duck and goose DNA. The method measures PCR product accumulation through a FAM-labeled fluorogenic probe (TaqMan). The C(t) (threshold cycle) values obtained from the duck + goose system are used to normalize the ones obtained from the duck-specific system. Analysis of experimental duck/goose foie gras binary mixtures demonstrated the suitability of the assay for the detection and quantitation of duck in the range of 1-25%. This genetic marker can be very useful to avoid mislabeling or fraudulent species substitution of goose by duck in foie gras.

    The cDNAs encoding two distinct type I interferon receptors were firstly cloned from the spleen of white goose (the Chinese goose, Anser cygnoides). The cDNA of goose IFNAR1 consisted of 1616 bp and encoded 406 amino acids with a predicted molecular weight of 46.4 kDa, while the cDNA of goose IFNAR2 consisted of 1525 bp and encoded 294 amino acids with a predicted molecular weight of 32.6 kDa. The IFNAR1 shared 85.4% identity in deduced amino acid sequence with duck IFNAR1, while IFNAR2 amino acid sequence showed 86% identity with that of duck IFNAR2. The age-related analysis of gene expression revealed that goose IFNα and IFNARs were all highly transcribed in pancreas, which may due to a reasonable amount of dendritic cells aggregated in pancreas. And goose IFNα and its cognate receptors had different structural features and tissue expression patterns during the period from embryonic goose to adult goose, suggesting that IFNα and IFNARs may maintain a developmental dynamic immune competence in unstimulated states. The data provided in this study may contribute to future understanding of the interaction between interferon and interferon receptors in immune mechanism. And it also helps us to understand the age-related susceptibility to pathogens in birds better. PMID:25617523

    In the present study, monoclonal antibodies (MAbs) against NS1 protein of Goose parvovirus (GPV) were generated. The secreted MAbs were obtained by fusing mouse myeloma cells and spleen cells of BALB/c mice, which were immunized with the plasmid pcDNA3.1-GPV-NS1 and recombinant protein of GPV-NS1. With indirect ELISA, six hybridoma cell lines against GPV-NS1 were screened. The subtypes of the two MAbs were IgG2a; the others were IgM. The light chain was κ. Western blot analysis showed that six MAbs reacted with recombinant protein GPV-NS1. GPV-NS1 was dissected into 15 overlapping epitopes, which were used to react with MAbs in Western blot. Results showed that six MAbs recognized NS1 protein linear B-cell epitopes located at the C-terminus 453-514 aa, 485-542 aa, and 533-598 aa.

    Polymerase chain reaction amplification of a conserved region of the α-actin gene has been used for the specific identification of goose (Anser anser) and mule duck (Anas platyrhynchos×Cairina moschata) foie gras. Universal primers were used for the amplification of a DNA fragment containing three introns and four exons of the α-actin gene in goose and mule duck. Sequence analysis of the amplified fragments was necessary for the design of forward species-specific primers in the goose and mule duck α-actin genes. The use of species-specific forward primers, together with a reverse universal primer, produced amplicons of different length, allowing clear identification of goose and mule duck foie gras samples. Analysis of experimental mixtures demonstrated that 1% of duck can be easily detected in goose foie gras using the PCR method developed here. This genetic marker can be very useful for the accurate identification of these two species in foie gras products.

    It is known that endoplasmic reticulum stress (ERS) contributes to insulin resistance (IR) and non-alcoholic fatty liver disease (NAFLD) in mammals. However, we recently demonstrated that overfeeding with a traditional diet (mainly consisting of cooked maize) does not induce ERS in goose. As cellular studies show that high glucose and palmitate can trigger ERS in mammalian cells, we hypothesized that supplementing sugar to the traditional diet could induce ERS, thus promoting insulin resistance and fatty liver. To test the hypothesis, we first treated goose primary hepatocytes with high glucose (25 mM and 50 mM) and palmitate (0.5 mM) supplemented with or without 0.25 mM oleate. Data indicated that, as in mammalian cells, high glucose and palmitate indeed induced ERS in goose primary hepatocytes, and palmitate-induced ERS was suppressed by supplemental 0.25 mM oleate. We then tested the hypothesis with an in vivo study, in which Landes geese overfed with traditional or novel diets (i.e., the traditional diet supplemented with sugar) were compared with control geese (normally fed with cooked maize) for ERS, IR and fatty liver. The differences in glucose tolerance, insulin tolerance and postprandial blood glucose between the geese overfed with traditional and novel diets suggested that supplementing dietary sugar promoted IR. This promotion was accompanied with an increasing trend of liver weight and abdominal fat weight relative to body weight. Surprisingly, compared to overfeeding with the traditional diet, overfeeding with the novel diet did not induce ERS, even further suppressed ERS in goose fatty liver. Together, our findings suggest that supplementing dietary sugar promotes ERS-independent IR and fatty liver in goose. It is intriguing to discover the factor(s) protecting goose liver from ERS as well as the non-ERS mechanism underlying IR. PMID:27246737

    Full Text Available Since human-wildlife conflicts are increasing, the development of cost-effective methods for reducing damage or conflict levels is important in wildlife management. A wide range of devices to detect and deter animals causing conflict are used for this purpose, although their effectiveness is often highly variable, due to habituation to disruptive or disturbing stimuli. Automated recognition of behaviours could form a critical component of a system capable of altering the disruptive stimuli to avoid this. In this paper we present a novel method to automatically recognise goose behaviour based on vocalisations from flocks of free-living barnacle geese (Branta leucopsis. The geese were observed and recorded in a natural environment, using a shielded shotgun microphone. The classification used Support Vector Machines (SVMs, which had been trained with labeled data. Greenwood Function Cepstral Coefficients (GFCC were used as features for the pattern recognition algorithm, as they can be adjusted to the hearing capabilities of different species. Three behaviours are classified based in this approach, and the method achieves a good recognition of foraging behaviour (86–97% sensitivity, 89–98% precision and a reasonable recognition of flushing (79–86%, 66–80% and landing behaviour(73–91%, 79–92%. The Support Vector Machine has proven to be a robust classifier for this kind of classification, as generality and non-linearcapabilities are important. We conclude that vocalisations can be used to automatically detect behaviour of conflict wildlife species, and as such, may be used as an integrated part of awildlife management system.

    Examination of 46 Canada goose goslings yielded 14 species of parasites, including five Protozoa, four Nematoda, two Cestoda, and three Trematoda. Evidence indicates that goslings acquired most of these infections during their first week of life. Some parasites, Prosthogonimus sp., occurred only in younger birds. Others, Leucocytozoon simondi, were evident only during the initial course of infection, while still others remained evident in older geese. Parasites with a direct life cycle appeared to be more prevalent than those requiring intermediate hosts. Among 29 birds from a refuge in Michigan, 14 species of parasites were found; while in 17 goslings from a Utah refuge, only five species occurred.

    The Light Goose Conservation Order (LGCO) was initiated in 1999 to reduce mid-continent populations of light geese (lesser snow geese Chen caerulescens and Ross's geese C. rossi). However, concern about potential for LGCO activities (i.e. hunting activities) to negatively impact non-target waterfowl species during spring migration in the Rainwater Basin (RWB) of Nebraska prompted agency personnel to limit the number of hunt days each week and close multiple public wetlands to LGCO activities entirely. To evaluate the effects of the LGCO in the RWB, we quantified waterfowl density at wetlands open and closed to LGCO hunting and recorded all hunter encounters during springs 2011 and 2012. We encountered a total of 70 hunting parties on 22 study wetlands, with over 90% of these encounters occurring during early season when the majority of waterfowl used the RWB region. We detected greater overall densities of dabbling ducks Anas spp., as well as for mallards A. platyrhynchos and northern pintails A. acuta on wetlands closed to the LGCO. We detected no effects of hunt day in the analyses of dabbling duck densities. We detected no differences in mean weekly dabbling duck densities among wetlands open to hunting, regardless of weekly or cumulative hunting encounter frequency throughout early season. Additionally, hunting category was not a predictor for the presence of greater white-fronted geese Anser albifronsin a logistic regression model. Given that dabbling duck densities were greater on wetlands closed to hunting, providing wetlands free from hunting disturbance as refugia during the LGCO remains an important management strategy at migration stopover sites. However, given that we did not detect an effect of hunt day or hunting frequency on dabbling duck density, our results suggest increased hunting frequency at sites already open to hunting would likely have minimal impacts on the distribution of non-target waterfowl species using the region for spring

    Canada has an extremely successful hypertension detection and treatment program. The aim of this review was to highlight the historic and current infrastructure and initiatives that have led to this success, and the outlook moving forward into the future. We discuss the evolution of hypertension awareness and control in Canada; contributions made by organizations such as the Canadian Hypertension Society, Blood Pressure Canada, and the Canadian Hypertension Education Program; the amalgamation of these organizations into Hypertension Canada; and the impact that Hypertension Canada has had on hypertension care in Canada. The important contribution that public policy and advocacy can have on prevention and control of blood pressure in Canada is described. We also highlight the importance of population-based strategies, health care access and organization, and accurate blood pressure measurement (including ambulatory, home, and automated office modalities) in optimizing hypertension prevention and management. We end by discussing how Hypertension Canada will move forward in the near and longer term to address the unmet residual risk attributable to hypertension and associated cardiovascular risk factors. Hypertension Canada will continue to strive to enhance hypertension prevention and control rates, thereby improving the quality of life and cardiovascular outcomes of Canadians, while at the same time creating a hypertension care model that can be emulated across the world.

    An assay protocol based on a monoclonal antibody-based competitive enzyme-linked immunosorbent assay (MAb-based C-ELISA) for detecting antibodies against goose parvovirus (GPV) and its virus-like particles (VLPs) is described. The assay was developed using baculovirus-expressed recombinant VP2 virus-like particles (rVP2-VLPs) as antigens and a monoclonal antibody against GPV as the competitive antibody. Of the four anti-GPV MAbs that were screened, MAb 1G3 was selected as it was blocked by the GPV positive serum. Based on the distribution of percent inhibition (PI) of the known negative sera (n=225), a cut-off value was set at 36% inhibition. Using this cut-off value, the sensitivity of the assay was 93.3% and the specificity was 95.8%, as compared with the gold standard (virus neutralization assay). The rVP2-VLPs did not react with anti-sera to other goose pathogens, indicating that it is specific for the recognization of goose parvovirus antibodies. The assay was then validated with serum samples from goslings vaccinated with several VLPs (rVP1-VLPs, rVP2-VLPs, rVP3-VLPs, and rCGV-VLPs) and other vaccines (inactivated and attenuated). The C-ELISA described in this study is a sensitive and specific diagnostic test and should have wide applications for the sero-diagnosis and immunologic surveillance of GPV.

    Wild populations of the world’s most common dabbling duck, the mallard (Anas platyrhynchos), run the risk of genetic introgression by farmed conspecifics released for hunting purposes. We tested whether bill morphology of free-living birds has changed since large-scale releases of farmed mallards started. Three groups of mallards from Sweden, Norway and Finland were compared: historical wild (before large-scale releases started), present-day wild, and present-day farmed. Higher density of bill lamellae was observed in historical wild mallards (only males). Farmed mallards had wider bills than present-day and historical wild ones. Present-day wild and farmed mallards also had higher and shorter bills than historical wild mallards. Present-day mallards thus tend to have more “goose-like” bills (wider, higher, and shorter) than their ancestors. Our study suggests that surviving released mallards affect morphological traits in wild population by introgression. We discuss how such anthropogenic impact may lead to a maladapted and genetically compromised wild mallard population. Our study system has bearing on other taxa where large-scale releases of conspecifics with ‘alien genes’ may cause a cryptic invasive process that nevertheless has fitness consequences for individual birds.

    In a current study at the University Hospital Dresden, Department of Neurology, the autonomous function of nerve fibres of the human skin is investigated. For this purpose, a specific medicament is applied on a small area of the skin of a test person which results in a local reaction (goose bumps). Based on the extent of the area, where the stimulation of the nerve fibres is visible, it can be concluded how the nerve function of the skin works. The aim of the investigation described in the paper is to generate 3D data of these goose bumps. Therefore, the paper analyses and compares different photogrammetric surface measurement techniques in regard to their suitability for the 3D acquisition of silicone imprints of the human skin. Furthermore, an appropriate processing procedure for analysing the recorded point cloud data is developed and presented. It was experimentally proven that by using (low-cost) photogrammetric techniques medicamentous induced goose bumps can be acquired in three dimensions and can be analysed almost fully automatically from the perspective of medical research questions. The relative accuracy was determined with 1% (RMSE) of the area resp. the volume of an individual goose bump.

    Agouti signalling protein (ASIP) is an endogenous antagonist of melanocortin-1 receptor (MC1R) and is involved in the regulation of pigmentation in mammals. The objective of this study was to identify and characterise the ASIP gene in domestic goose. The goose ASIP cDNA consisted of a 44-nucleotide 5'-terminal untranslated region (UTR), a 390-nucleotide open-reading frame (ORF) and a 45-nucleotide 3'-UTR. The length of goose ASIP genomic DNA was 6176 bp, including three coding exons and two introns. Bioinformatic analysis indicated that the ORF encodes a protein of 130 amino-acid residues with a molecular weight of 14.88 kDa and an isoelectric point of 9.73. Multiple sequence alignments and phylogenetic analysis showed that the amino-acid sequence of ASIP was conserved in vertebrates, especially in the avian species. RT-qPCR showed that the goose ASIP mRNA was differentially expressed in the pigment deposition tissues, including eye, foot, feather follicle, skin of the back, as well as in skin of the abdomen. The expression level of the ASIP gene in skin of the abdomen was higher than that in skin of the back. Those findings will contribute to further understanding the functions of the ASIP gene in geese plumage colouring. PMID:26750999

    The goose is an economically important waterfowl that exhibits unique characteristics and abilities, such as liver fat deposition and fibre digestion. Here, we report de novo whole-genome assemblies for the goose and swan goose and describe the evolutionary relationships among 7 bird species, including domestic and wild geese, which diverged approximately 3.4~6.3 million years ago (Mya). In contrast to chickens as a proximal species, the expanded and rapidly evolving genes found in the goose genome are mainly involved in metabolism, including energy, amino acid and carbohydrate metabolism. Further integrated analysis of the host genome and gut metagenome indicated that the most widely shared functional enrichment of genes occurs for functions such as glycolysis/gluconeogenesis, starch and sucrose metabolism, propanoate metabolism and the citrate cycle. We speculate that the unique physiological abilities of geese benefit from the adaptive evolution of the host genome and symbiotic interactions with gut microbes. PMID:27608918

  1. Environmental radioactivity in Canada 1986

    International Nuclear Information System (INIS)

    The radiological surveillance program of the Department of National Health and Welfare is conducted for the purpose of determining levels of environmental radioactivity in Canada and assessing the resulting population exposures. During 1986 the program was strongly influenced by radioactive fallout on Canada resulting from the Chernobyl nuclear reactor accident on April 26, 1986 in the Soviet Ukraine. The Environmental Radiation Hazards Division (ERHD) increased its frequency of analyses of environmental samples immediately following the accident. Interim screening limits for foodstuffs were developed. A measurement program for radioactivity in domestic and imported foods was implemented. The ERHD measurement program was supplemented by additional measurements conducted by many other private and government laboratories. Radiation doses to Canadian from Chernobyl fallout were extremely low with no group in the population receiving more than 10 microsieverts

    Stocking represents the most important management tool worldwide to increase and sustain commercial and recreational fisheries in a context of overexploitation. Genetic impacts of this practice have been investigated in many studies, which examined population and individual admixture, but few have investigated determinants of these processes. Here, we addressed these questions from the genotyping at 19 microsatellite loci of 3341 adult lake trout (Salvelinus namaycush) from 72 unstocked and stocked lakes. Results showed an increase in genetic diversity and a twofold decrease in the extent of genetic differentiation among stocked populations when compared to unstocked. Stocked populations were characterized by significant admixture at both population and individual levels. Moreover, levels of admixture in stocked populations were strongly correlated with stocking intensity and a threshold value of total homogenization between source and stocked populations was identified. Our results also suggest that under certain scenarios, the genetic impacts of stocking could be of short duration. Overall, our study emphasizes the important alteration of the genetic integrity of stocked populations and the need to better understand determinants of admixture to optimize stocking strategies and to conserve the genetic integrity of wild populations.

  4. Indigenous Educational Attainment in Canada

    Full Text Available In this article, the educational attainment of Indigenous peoples of working age (25 to 64 years in Canada is examined. This diverse population has typically had lower educational levels than the general population in Canada. Results indicate that, while on the positive side there are a greater number of highly educated Indigenous peoples, there is also a continuing gap between Indigenous and non-Indigenous peoples. Data also indicate that the proportion with less than high school education declined, which corresponds with a rise of those with a PSE; the reverse was true in 1996. Despite these gains, however, the large and increasing absolute numbers of those without a high school education is alarming. There are intra-Indigenous differences: First Nations with Indian Status and the Inuit are not doing as well as non-Status and Métis peoples. Comparisons between the Indigenous and non-Indigenous populations reveal that the documented gap in post-secondary educational attainment is at best stagnant. Out of the data analysis, and based on the history of educational policy, we comment on the current reform proposed by the Government of Canada, announced in February of 2014, and propose several policy recommendations to move educational attainment forward.

Expression of the whole VP3 protein provided an insufficient amount of protein. In contrast, the expression of two VP3 epitopes (VP3ep4, VP3ep6) in E. coli, resulted in very high expression levels. This may suggest that smaller parts of the GPV antigenic determinants are more efficiently expressed than the complete VP3 gene.

    Leptin is critical for reproductive endocrinology. The aim of this study is to assess the expression patterns of leptin receptor (Lepr) during ovarian follicle development and to reveal the mechanism by which leptin affects steroid hormone secretion in goose granulosa cells. Transcripts of Lepr were ubiquitous in all tested tissues, with pituitary and adrenal glands being the predominant sites. Goose ovarian follicles were divided into several groups by diameter including prehierarchical (4 to 6, 6 to 8, and 8 to 10 mm) and hierarchical (F5-F1) follicles. Lepr gene expression was significantly higher in granulosa cells than in theca cells from follicles of 4 to 8 mm in diameter. Expression of Lepr in granulosa cells decreased gradually as follicles developed, with fluctuating expression in F5 and F3 follicles. Lepr mRNA in theca cells underwent a slight decrease from the 6- to 8-mm cohorts to F5 follicle and then exhibited a transient increase and declined later. In vitro experiments in cultured goose granulosa cells showed that estradiol release was significantly stimulated, whereas progesterone increased slightly and testosterone decreased dramatically after leptin treatment. In accordance with the data for steroids, expression of Lepr, Srebp1, Cyp51, StAR, and Cyp19a1 were induced by the addition of leptin, and the concomitant changes in Hmgcs1, Dhcr24, Cyp11a1, 17β-hsd, Cyp17, and 3β-hsd gene expression were seen. These results suggested that leptin is involved in the development of goose ovarian follicles, and leptin's effect on steroid hormone secretion could be due to altered sterol/steroidogenic gene expression via interaction with its receptor.

    Canada is a high-income country with a population of 33 million people. Its economic performance has been solid despite the recession that began in 2008. Life expectancy in Canada continues to rise and is high compared with most OECD countries; however, infant and maternal mortality rates tend to be worse than in countries such as Australia, France and Sweden. About 70% of total health expenditure comes from the general tax revenues of the federal, provincial and territorial governments. Most public revenues for health are used to provide universal medicare (medically necessary hospital and physician services that are free at the point of service for residents) and to subsidise the costs of outpatient prescription drugs and long-term care. Health care costs continue to grow at a faster rate than the economy and government revenue, largely driven by spending on prescription drugs. In the last five years, however, growth rates in pharmaceutical spending have been matched by hospital spending and overtaken by physician spending, mainly due to increased provider remuneration. The governance, organization and delivery of health services is highly decentralized, with the provinces and territories responsible for administering medicare and planning health services. In the last ten years there have been no major pan-Canadian health reform initiatives but individual provinces and territories have focused on reorganizing or fine tuning their regional health systems and improving the quality, timeliness and patient experience of primary, acute and chronic care. The medicare system has been effective in providing Canadians with financial protection against hospital and physician costs. However, the narrow scope of services covered under medicare has produced important gaps in coverage and equitable access may be a challenge in these areas.

    European Union regulations state that consumers must be rightfully informed about the provenance of fishery products to prevent fraudulent practices. However, mislabeling of the geographical origin is a common practice. It is therefore paramount to develop forensic methods that allow all players involved in the supply chain to accurately trace the origin of seafood. In this study, trace elemental signatures (TES) of the goose barnacle Pollicipes pollicipes, collected from ten sites along the Portuguese coast, were employed to discriminate individual's origin. Barium (Ba), boron (B), cadmium (Cd), chromium (Cr), lithium (Li), magnesium (Mg), manganese (Mn), phosphorous (P), lead (Pb), strontium (Sr) and zinc (Zn) - were quantified using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Significant differences were recorded among locations for all elements. A regularized discriminant analysis (RDA) revealed that 83% of all individuals were correctly assigned. This study shows TES can be a reliable tool to confirm the geographic origin of goose barnacles at fine spatial resolution. Although additional studies are required to ascertain the reliability of TES on cooked specimens and the temporal stability of the signature, the approach holds great promise for the management of goose barnacles fisheries, enforcement of conservation policies and assurance in accurate labeling.

    Full Text Available Understanding the dynamic of metals in soil and plants and population diversity in Northern Ontario is essential in determining progress toward ecosystem sustainability in reclaimed sites. The objectives of the present study were to assess the levels of metal content in soils and their accumulation in red oak plants from limed and unlimed sites. Genetic variation in red oak populations from the Northern Ontario region was also analyzed. The levels of soil acidity was lower in limed areas compared to un limed sites, an indication of the prolonged beneficial effect of liming 20 to 30 years ago on soil toxicity. The levels of total metals were very high for most elements, but the proportion of metals that were bio available and readily available to plants was very small. The enrichment factors were16.78, 4.98 and 2.94 for total arsenic, copper and nickel, respectively. The Translocation Factor (TF values for available metals from soil to branches were high. There was more metal accumulation in leaves compared to branches. The degrees of genetic variability in red oak populations from limed and unlimed areas were compared using ISSR markers. The levels of polymorphic loci were moderate to high ranging from 44 to 65%. There were no significant differences in polymorphisms between areas that were limed and unlimed. Overall the red oak populations in stressed areas in Northern Ontario are sustainable.

    Small dams are often used for irrigation, municipal water supplies and storm water management. Small dams outnumber large hydro-electric projects in Canada by a wide margin, and tend to be located closer to large population centres. Despite their lower profile with the general public, small dams frequently have high consequence classifications. This study discussed the distribution of various consequence classifications for small dams of varying heights. Databases from different Canadian provinces were used to develop sets of statistics on dam features, the distribution of risk, and other relevant information. Approximately 6000 dams were classified in the database. Of these, 444 were greater than 15 metres in height. A significant portion of with high consequence classifications qualified as small dams, and the majority of the high consequence dams were under 10 metres in height. The largest population of dam owners have limited resources available for adequate engineering design, construction supervision, and dam safety management programs. It was concluded that economical methods of estimating probable maximum flood (PMF) rates are needed for small dams. 8 refs., 5 tabs., 2 figs.

  15. Using 137Cs as a tool for the assessment and the management of erosion/sedimentation risks in view of the restoration of the Rainbow Smelt (Osmerus mordax) fish population in the Boyer River basin (Quebec, Canada)

    International Nuclear Information System (INIS)

    The Boyer River (Quebec, Canada) drains a 217 km2 watershed that is under cultivation at 60%. The last 2 km of the river bed has always been used as a spawning ground by Rainbow Smelts (Osmerus mordax). This fish population, which plays an important ecological role in the St. Lawrence River estuary, has dramatically declined over the last decades. Siltation and excessive algal growth in the spawning area were identified as the most probable causes of the fish population decline; suggesting that soil erosion, nutrient and sediment transport are major factors underlying the environmental problem. In this context, 137Cs provides an effective tool for investigating the magnitude and spatial distribution of long-term soil redistribution taking place in the watershed. Sampling of cultivated fields, riverbanks, bottom sediments and forested sites were thus undertaken to help understand the erosive behaviour of the watershed. Results obtained so far suggest in-field erosion rates of up to 13 t ha-1 yr-1 with net outputs reaching 11 t ha-1 yr-1. These results agree well with estimates obtained from the USLE. The 137Cs data indicate that fields located in the upstream half of the basin produce smaller sediment loadings than those in the downstream portion, despite higher soil erodibilities and more frequent use for annual crops. They also suggest that more than 75% of the sediment deposited in the spawning area originates from cultivated fields, and less than 25% from streambanks. (author)

  16. De novo transcriptomic analysis of peripheral blood lymphocytes from the Chinese goose: gene discovery and immune system pathway description.

    Full Text Available The Chinese goose is one of the most economically important poultry birds and is a natural reservoir for many avian viruses. However, the nature and regulation of the innate and adaptive immune systems of this waterfowl species are not completely understood due to limited information on the goose genome. Recently, transcriptome sequencing technology was applied in the genomic studies focused on novel gene discovery. Thus, this study described the transcriptome of the goose peripheral blood lymphocytes to identify immunity relevant genes.De novo transcriptome assembly of the goose peripheral blood lymphocytes was sequenced by Illumina-Solexa technology. In total, 211,198 unigenes were assembled from the 69.36 million cleaned reads. The average length, N50 size and the maximum length of the assembled unigenes were 687 bp, 1,298 bp and 18,992 bp, respectively. A total of 36,854 unigenes showed similarity by BLAST search against the NCBI non-redundant (Nr protein database. For functional classification, 163,161 unigenes were comprised of three Gene Ontology (Go categories and 67 subcategories. A total of 15,334 unigenes were annotated into 25 eukaryotic orthologous groups (KOGs categories. Kyoto Encyclopedia of Genes and Genomes (KEGG database annotated 39,585 unigenes into six biological functional groups and 308 pathways. Among the 2,757 unigenes that participated in the 15 immune system KEGG pathways, 125 of the most important immune relevant genes were summarized and analyzed by STRING analysis to identify gene interactions and relationships. Moreover, 10 genes were confirmed by PCR and analyzed. Of these 125 unigenes, 109 unigenes, approximately 87%, were not previously identified in the goose.This de novo transcriptome analysis could provide important Chinese goose sequence information and highlights the value of new gene discovery, pathways investigation and immune system gene identification, and comparison with other avian species as useful

    The SYG61v is an attenuated goose parvovirus (GPV) that has been used as a vaccine strain in China. The genome of SYG61v was sequenced to attempt to identify the genetic basis for the attenuation of this strain. The entire genome consists of 5102 nucleotides (nts), with four nt deletions compared to that of virulent strain B. The inverted terminal repeats (ITR) are 442 nts in length, of which 360 nts form a stem region, and 43 nts constitute the bubble region. Although mutations were observed throughout the ITR, no mismatch was found in the stem. Alignment with other pathogenic GPV strains (B, 82-0321, 06-0329, and YZ99-5) indicated that there are 10 and 11 amino acid mutations in the Rep1 and VP1 proteins of SYG61v, respectively. The complete genome of SYG61v was cloned into the pBluescript II vector and an infectious plasmid pSYG61v was generated. Infectious progeny virus was successfully rescued through transfection of the plasmid pSYG61v in embryonated goose eggs and yielded viral titers similar to its parental virus, as evaluated by ELD50.

    Exposure to indoor radon has been determined to be the second leading cause of lung cancer after tobacco smoking. Canadian population risk of radon induced lung cancer was assessed in 2005 with the radon distribution characteristics determined from a radon survey carried out in the late 1970s in 19 cities. In that survey, a grab sampling method was used to measure radon levels. The observed radon concentration in 14 000 Canadian homes surveyed followed a log–normal distribution with a geometr...

    This research examines the feasibility of analyzing tree cores to detect benzene, toluene, ethylbenzene, and m, p, o-xylene (BTEX) compounds and methyl tertiary-butyl ether (MTBE) in groundwater in eastern Canada subarctic environments, using a former landfill site in the remote community of Happy Valley-Goose Bay, Labrador. Petroleum hydrocarbon contamination at the landfill site is the result of environmentally unsound pre-1990s disposal of households and industrial solid wastes. Tree cores were taken from trembling aspen, black spruce, and white birch and analyzed by headspace-gas chromatography-mass spectrometry. BTEX compounds were detected in tree cores, corroborating known groundwater contamination. A zone of anomalously high concentrations of total BTEX constituents was identified and recommended for monitoring by groundwater wells. Tree cores collected outside the landfill site at a local control area suggest the migration of contaminants off-site. Tree species exhibit different concentrations of BTEX constituents, indicating selective uptake and accumulation. Toluene in wood exhibited the highest concentrations, which may also be due to endogenous production. Meanwhile, MTBE was not found in the tree cores and is considered to be absent in the groundwater. The results demonstrate that tree-core analysis can be useful for detecting anomalous concentrations of petroleum hydrocarbons, such as BTEX compounds, in subarctic sites with shallow unconfined aquifers and permeable soils. This method can therefore aid in the proper management of contamination during landfill operations and after site closures. PMID:27151238

    The VP3-encoding gene of goose parvovirus (GPV) Ep22 strain was cloned and expressed in Escherichia coli. The GPV VP3-encoding gene was 1605 bp in length, and it encoded a 534 amino acid protein with a predicted molecular mass of 59.9 kDa. The VP3 fusion protein expressed in E. coli was detected by goose and Muscovy duck anti-parvovirus polyclonal sera. In addition, an ELISA (VP3-ELISA) using the VP3 protein as the coating antigen for the detection of antibodies to GPV in geese and antibodies to Muscovy duck parvovirus (MDPV) in Muscovy ducks was developed. Compared to the virus neutralization test, the specificity and sensitivity of the VP3-ELISA was 90.2% and 95.2% for goose sera and 91.8% and 96.7% for Muscovy duck sera, respectively. The VP3-ELISA did not react with the anti-sera to other goose or duck pathogens, indicating that this protein is specific for the reorganization of goose or duck anti-parvovirus antibodies. Cross-reactivity between immunoglobulin G antibodies from geese and Muscovy ducks was also tested, and the results reflected the phylogenetic distance between these two birds when using the ELISA. In conclusion, the VP3-ELISA is a sensitive and specific method for detecting antibodies against GPV or MDPV.

    Background: In Ontario, pneumococcal conjugate vaccines (PCVs) have been sequentially introduced into the publicly funded childhood vaccination program since 2005. A 23-valent polysaccharide pneumococcal vaccine (PPV23) has been routinely recommended for adults aged 65 years and older since 1996. To determine the effect of herd immunity, we examined the epidemiology of invasive pneumococcal disease in adults aged 65 years and older. Methods: Invasive pneumococcal disease is a provincially reportable disease. We were therefore able to conduct a descriptive epidemiologic analysis that included assessing time trends for patients aged 65 years and older using surveillance data from 2007 to 2014. Using serotype information within the surveillance data, cases were grouped into categories according to vaccine type and periods and then compared using Poisson regression. Results: A total of 3825 cases of invasive pneumococcal disease were reported among adults aged 65 years and older, for an overall annualized incidence of 25.4 cases per 100 000 population. There was a decrease in incidence due to serotypes included in 7-valent PCV (3.0 to 0.7 cases per 100 000 population) (p herd immunity from the childhood program. A burden of illness due to unique PPV23 serotypes and those that are not covered by a vaccine exists and has increased over time. PMID:27730119

    Glaucous Gulls (Larus hyperboreus) nesting on the Yukon-Kuskokwim (Y-K) Delta frequently prey on juvenile waterfowl. We collected 434 Glaucous Gulls from late June to early August 1994 to examine diet. Identification of undigested prey tissue, based on DNA microsatellite loci, showed three species of goslings in gull stomachs: Emperor Goose (Chen canagica), White-fronted Goose (Anser albifrons), and Cackling Canada Goose (Branta canadensis minima). Gulls that nested inland and were collected > 1.6 km from the coast accounted for approximately 70% of the total gull predation on Emperor and Canada Geese, and 96% on White-fronted Geese. Our stratified sample of gull stomachs and aerial survey estimates of population size and distribution of gulls and juvenile geese enabled extrapolation of species-specific predation rates to the entire Y-K Delta. We estimated that a minimum of 21 000 Emperor Goose, 34 000 Canada Goose, and 16 000 White-fronted Goose goslings were consumed by 12 600 Glaucous Gulls during the brood-rearing period on the Y-K Delta in 1994. Minimum estimated take by gulls represented 33% of Cackling Canada Goose, 47% of Emperor Goose, and 39% of White-fronted Goose eggs estimated to have hatched in the same area as gull collections. Gulls selected the three species of geese approximately in proportion to their abundance. Although gull predation caused significant gosling mortality, its role in regulating goose populations on Y-K Delta remains unresolved.

    Little is known about the economic burden of chronic pain and how chronic pain affects health care utilization. We aimed to estimate the annual per-person incremental medical cost and health care utilization for chronic pain in the Ontario population from the perspective of the public payer. We performed a retrospective cohort study using Ontario health care databases and the electronically linked Canadian Community Health Survey (CCHS) from 2000 to 2011. We identified subjects aged ≥12 years from the CCHS with chronic pain and closely matched them to individuals without pain using propensity score matching methods. We used linked data to determine mean 1-year per-person health care costs and utilization for each group and mean incremental cost for chronic pain. All costs are reported in 2014 Canadian dollars. After matching, we had 19,138 pairs of CCHS respondents with and without chronic pain. The average age was 55 years (SD = 18) and 61% were female. The incremental cost to manage chronic pain was $1742 per person (95% confidence interval [CI], $1488-$2020), 51% more than the control group. The largest contributor to the incremental cost was hospitalization ($514; 95% CI, $364-$683). Incremental costs were the highest in those with severe pain ($3960; 95% CI, $3186-$4680) and in those with most activity limitation ($4365; 95% CI, $3631-$5147). The per-person cost to manage chronic pain is substantial and more than 50% higher than a comparable patient without chronic pain. Costs are higher in people with more severe pain and activity limitations. PMID:26989805

    2007-08-01

    Full Text Available Abstract Background Studies have shown patients who are delayed for surgical cardiac revascularization are faced with increased risks of symptom deterioration and death. This could explain the observation that operative mortality among persons undergoing coronary artery bypass surgery (CABG is higher among women than men. However, in jurisdictions that employ priority wait lists to manage access to elective cardiac surgery, there is little information on whether women wait longer than men for CABG. It is therefore difficult to ascertain whether higher operative mortality among women is due to biological differences or to delayed access to elective CABG. Methods Using records from a population-based registry, we compared the wait-list time between women and men in British Columbia (BC between 1990 and 2000. We compared the number of weeks from registration to surgery for equal proportions of women and men, after adjusting for priority, comorbidity and age. Results In BC in the 1990s, 9,167 patients aged 40 years and over were registered on wait lists for CABG and spent a total of 136,071 person-weeks waiting. At the time of registration for CABG, women were more likely to have a comorbid condition than men. We found little evidence to suggest that women waited longer than men for CABG after registration, after adjusting for comorbidity and age, either overall or within three priority groups. Conclusion Our findings support the hypothesis that higher operative mortality during elective CABG operations observed among women is not due to longer delays for the procedure.

    Highlights: {yields} All three capsid proteins can be expressed in insect cells in baculovirus expression system. {yields} All three recombinant proteins were spontaneously self-assemble into virus-like particles whose size and appearance were similar to those of native purified GPV virions. {yields} The immunogenicity of GPV-VLPs was better than commercial inactivated vaccine and attenuated vaccine. -- Abstract: Goose parvovirus (GPV), a small non-enveloped ssDNA virus, can cause Derzsy's disease, and three capsid proteins of VP1, VP2, and VP3 are encoded by an overlapping nucleotide sequence. However, little is known on whether recombinant viral proteins (VPs) could spontaneously assemble into virus-like particles (VLPs) in insect cells and whether these VLPs could retain their immunoreactivity and immunogenicity in susceptible geese. To address these issues, genes for these GPV VPs were amplified by PCR, and the recombinant VPs proteins were expressed in insect cells using a baculovirus expression system for the characterization of their structures, immunoreactivity, and immunogenicity. The rVP1, rVP2, and rVP3 expressed in Sf9 cells were detected by anti-GPV sera, anti-VP3 sera, and anti-His antibodies, respectively. Electron microscopy revealed that these rVPs spontaneously assembled into VLPs in insect cells, similar to that of the purified wild-type GPV virions. In addition, vaccination with individual types of VLPs, particularly with the rVP2-VLPs, induced higher titers of antibodies and neutralized different strains of GPVs in primary goose and duck embryo fibroblast cells in vitro. These data indicated that these VLPs retained immunoreactivity and had strong immunogenicity in susceptible geese. Therefore, our findings may provide a framework for development of new vaccines for the prevention of Derzsy's disease and vehicles for the delivery of drugs.

    1988-01-01

    The domestic goose is hyperphagic after a fast resulting in a 40% decrease in body mass (a decrease similar to that during breeding anorexia). Food intake is maximum on the 8th day of refeeding. As it is then an average of 2.5 times higher than before the fast, food intake may thus reach the value during forced-feeding for "foie gras". Since nitrogen assimilation rate also increases 2.5 times, nitrogen fixation is increased 6.8 times, suggesting a high level of protein synthesis.

  2. Natural background radiation in Canada

    International Nuclear Information System (INIS)

    Published airborne gamma ray survey data from 33 areas of Canada were used to compile information on the average ground level exposure from natural radiation. The exposures at ground level were calculated from the surface concentrations of potassium, uranium and thorium. The highest levels of radioactivity were found in northern Canada and were generally related to granitic rocks; the lowest levels with the Athabasca sandstone. Summer outdoor exposure rates have a population-weighted average of 3.7 +- 2.3 μR.h-1, of which 48 percent orginated from potassium, 43 percent from the thorium series and 9 percent from the uranium series. This low level of radioactivity, compared to worldwide data, has resulted from erosion of a geologically old continental crust in which radioactivity decreases with depth. When seasonal variations of soil moisture and snow cover are considered, the annual population-weighted average outdoor exposure rate decreases to 2.8 +- 1.7 μR.h-1 corresponding to an annual outdoor dose-equivalent of 150 +- 90 μSV. Factors increasing the annual outdoor dose-equivalent are cosmic radiation (320 +- 30 μSV) and the internal radioactivity of the body (190 μSV). Using the ratio between indoor and outdoor values for worldwide published data, the average annual Canadian whole-body dose-equivalent from all sources of natural radiation is estimated to be 690 +-130 μSV

  5. A comparison of field-line resonances observed at the Goose Bay and Wick radars

    Directory of Open Access Journals (Sweden)

    G. Provan

    Full Text Available Previous observations with the Goose Bay HF coherent-scatter radar have revealed structured spectral peaks at ultra-low frequencies. The frequencies of these spectral peaks have been demonstrated to be extremely consistent from day to day. The stability of these spectral peaks can be seen as evidence for the existence of global magnetospheric cavity modes whose resonant frequencies are independent of latitude. Field-line resonances occur when successive harmonics of the eigenfrequency of the magnetospheric cavity or waveguide match either the first harmonic eigenfrequency of the geomagnetic field lines or higher harmonics of this frequency. Power spectra observed at the SABRE VHF coherent-scatter radar at Wick, Scotland, during night and early morning are revealed to show similarly clearly structured spectral peaks. These spectral peaks are the result of local field-line resonances due to Alfvén waves standing on magnetospheric field lines. A comparison of the spectra observed by the Goose Bay and Wick radars demonstrate that the frequencies of the field-line resonances are, on average, almost identical, despite the different latitudinal ranges covered by the two radars. Possible explanations for the similarity of the signatures on the two radar systems are discussed.

    In this study, the complete genome of the virulent strain LH of goose parvovirus (GPV) was sequenced and cloned into the pBluescript II (SK) plasmid vector. Sequence alignments of the inverted terminal repeats (ITR) of GPV strains revealed a common 14-nt-pair deletion in the stem of the palindromic structure in the LH strain and three other strains isolated after 1982 when compared to three GPV strains isolated earlier than that time. Transfection of 11-day-old embryonated goose eggs with the plasmid pLH, which contains the entire genome of strain LH, resulted in successful rescue of the infectious virus. Death of embryos after transfection via the chorioallantoic membrane infiltration route occurred earlier than when transfection was done via the allantoic cavity inoculation route. The rescued virus exhibited virulence similar to that of its parental virus, as evaluated by the mortality rate in goslings. Generation of the pathogenic infectious clone provides us with a powerful tool to elucidate the molecular pathogenesis of GPV in the future.

  7. Molecular Analysis of Hemagglutinin Gene of a Goose Origin Highly Pathogenic Avian Influenza Virus

    Chen Hualan; Yu Kangzhen; Bu Zhigao

    2000-01-01

    The hemagglutinin (HA) of avian influenza virus (AIV) plays a key role in determining the pathogenicity, cell receptor-binding property and host range of the virus. A goose origin AIV A/Goose/Guangdong/1/96(H5N1) (GD/96) was confirmed as a highly pathogenic AIV (HPAIV) by the tests of intravenous pathogenic index (IVPI) and the assay of plaque formation. The sequence results of the HA gene cDNA of the isolate reveal that there is an insertion of 6 basic amino acids ( R-R-R-K-K-R-) in the cleavage site between the HA1 and HA2, which is the characterization of the H5 subtype HPAIV. When compared with the lethal A/Hongkong/156/97 (H5N1) (HK/97), there is a homology of 98% at the nucleotide level and 98. 2% at the amino acid level. Furthermore, no difference of nucleotides related to all of the 6 potential glycosylation sites, the 2 receptor-binding sites and the basic amino acid insert within the HA existed between GD/96 and HK/97. These results imply that the GD/96 and HK/97 have a closely related common ancestor and share the same biological properties decided by the HA.

    Polymerase chain reaction (PCR) amplification of the nuclear 5S rDNA gene has been used for the identification of goose and mule duck foie gras. Two species-specific reverse primers were designed and used in a multiplex reaction, together with a forward universal primer, to amplify specific fragments of the 5S rDNA in each species. The different sizes of the species-specific amplicons, separated by agarose gel electrophoresis, allowed clear identification of goose and mule duck foie gras samples. This genetic marker can be useful for detecting fraudulent substitution of the duck liver for the more expensive goose liver.

  13. Poisoning of Canada geese in Texas by parathion sprayed for control of Russian wheat aphid

    Science.gov (United States)

    Flickinger, Edward L.; Juenger, Gary; Roffe, Thomas J.; Smith, Milton R.; Irwin, Roy J.

    1991-01-01

    Approximately 200 Canada geese (Branta canadensis) died at a playa lake in the Texas Panhandle shortly after a winter wheat field in the basin adjacent to the lake was treated with parathion to control newly invading Russian wheat aphids (Diuraphis noxia). No evidence of infectious disease was diagnosed during necropsies of geese. Brain ChE activities were depressed up to 77% below normal. Parathion residues in GI tract contents of geese ranged from 4 to 34 ppm. Based on this evidence, parathion was responsible for the goose mortalities. Parathion applications to winter wheat will undoubtedly increase if parathion is applied for control of both Russian wheat aphids and greenbugs (Schizaphis graminum). Geese may potentially be exposed to widespread applications of parathion from fall to spring, essentially their entire wintering period.

  14. Isolation and partial characterization of the gene for goose fatty acid synthase.

    Science.gov (United States)

    Kameda, K; Goodridge, A G

    1991-01-01

    Fatty acid synthase is regulated by diet and hormones, with regulation being primarily transcriptional. In chick embryo hepatocytes in culture, triiodothyronine stimulates accumulation of enzyme and transcription of the gene. Since the 5'-flanking region of this gene is likely involved in hormonal regulation of its expression, we have isolated and partially characterized an avian fatty acid synthase gene. A genomic DNA library was constructed in a cosmid vector and screened with cDNA clones that contained sequence complementary to the 3' end of goose fatty acid synthase mRNA. A genomic clone (approximately 35 kilobase pairs (kb] was isolated, and a 6.5-kb EcoRI fragment thereof contained DNA complementary to the 3' noncoding region of fatty acid synthase mRNA. Additional cosmid libraries were screened with 5' fragments of previously isolated genomic clones, resulting in the isolation of five overlapping cosmid DNAs. The entire region of cloned DNA spans approximately 105 kb. Exon-containing fragments were identified by hybridization with end-labeled poly(A)+ RNA and by hybridization of labeled exon-containing genomic DNA fragments to fatty acid synthase mRNA. A new set of cDNA clones spanning approximately 3.2 kb was isolated from a lambda-ZAP goose liver cDNA library using the 5'-most exon-containing fragment of the 5'-most genomic DNA clone. This region of mRNA contains a 5'-untranslated sequence and a continuous open reading frame which includes a region that codes for the essential cysteine of the beta-ketoacyl synthase domain. The entire fatty acid synthase gene spans about 50 kb. The 5' 15 kb of the gene contain 7 exons. S1 nuclease and primer extension analyses were used to identify a single site for initiation of transcription, 174 nucleotides upstream from the putative translation initiation codon. Putative "TATA" and "CCAAT" boxes are located 28 and 60 base pairs (bp), respectively, upstream of the site of initiation of transcription. The 5'-flanking 597

The genotypes of 240 individuals were detected and the genetic variation between populations of these two breeds were analysed by computing the advantage allele frequencies, expected heterozygosity, polymorphism information content (PIC)and population inbreeding coefficients (Fis).The genetic variations between the gene pool populations and the original ones by using paired experiment mean t test. The advantage Pi of these two breeds were not significantly different in the four populations (Pst=0.197, PWX =0.219);He,PIC were slightly higher than the original populations,but the differences were also not significant (Phe=0.063, PPIC =0.144,Phe=0.230, PpIC=0.195 );Fis were lower than the original populations but the differences were not significant(PST=0.111, PWX=0.130). The results showed that these two breeds were preserved perfectly in the gene

    The radiological surveillance program of the Department of National Health and Welfare is conducted for the purpose of determining levels of environmental radioactivity in Canada and assessing the resulting population exposures. Following major changes to the CAMECO Port Hope operations to reduce uranium emissions, a study was initiated to measure uranium levels in air in the community. Studies continued on lung cancer and domestic exposure to radon, and current levels of cesium-137 in caribou, a major source of food in northern communities. The movement of tritium on the Ottawa and St. Lawrence rivers was studied following an accidental release into the Ottawa River. Monitoring continued of fallout contamination from Chernobyl in imported foods. All measurements recorded during 1988 were below the limits recommended by the International Commission on Radiological Protection. (14 refs., 14 figs., 15 tabs.)

    In practice, goose eggs are increasingly used and, therefore, the rheological properties have to be known for processing. The eggs of geese (Landes Goose, Anser anser f. domestica) were stored for one, 2, 3, 4, 6, and 8 wk at a constant temperature 4°C. First of all, the egg quality parameters were described in terms of egg weight, egg weight loss, egg shape index, yolk height, albumen height, yolk index, albumen index, and Haugh units. In the next step the rheological behavior of liquid egg products (egg yolk, albumen, and whole liquid egg) was studied using a concentric cylinder viscometer. Flow curves of all liquid egg products exhibited non-Newtonian shear thinning behavior. This behavior can be described using the Herschel-Bulkley model and for technical application using the Ostwald-de Waele model. The effect of the storage duration on the rheological behavior is different for the different liquid egg products. With the exception of very low shear rates, the viscosity of the egg yolk as well as of the whole liquid egg decreases with storage time. At lower shear rates there is a tendency toward increased albumen viscosity with storage duration. The storage duration also affects the mechanical properties of the eggshell membrane. This effect has been evaluated in terms of the ultimate tensile strength, fracture strain, and fracture toughness. All these parameters increased with the loading rate, but decreased during the egg storage. These mechanical phenomena should be respected, namely in the design of the egg model for the numerical simulation of the egg behavior under different kinds of the mechanical loading.

  18. Differential channelling of liver lipids in relation to susceptibility to hepatic steatosis in the goose.

    1999-10-01

    In response to overfeeding for the production of "foie gras," the Poland goose differs from the Landes goose by a lesser susceptibility to hepatic steatosis, resulting in a lower accumulation of hepatic triacylglycerol (TG), together with a greater exportation of hepatic phospholipid (PL) in very low density lipoproteins (VLDL) and high density lipoproteins (HDL) (Fournier et al., 1997). A study was designed 1) to compare the liver composition in overfed and nonoverfed geese of the two breeds of geese and 2) to determine whether the differential channelling of lipids in response to overfeeding is reflected in the PL and fatty acid profiles of the different hepatic lipids, whether stored or secreted. In nonoverfed geese, there were no breed-related differences in liver weight (approximately 90 to 100 g), hepatic lipid content (3 to 4%), and lipid and PL composition. However, plasma VLDL and HDL of the Landes breed contained a higher phosphatidylcholine (PC) to phosphatidylethanolamine (PE) ratio than those of the Poland breed (20.7 and 33.8 vs 12.6 and 25.6 in VLDL and HDL, respectively). After 14 d of overfeeding, hepatic PL profiles were identical in the two breeds and similar to that in control livers; choline-containing PL accounted for 95% of total PL. In contrast, plasma HDL concentrations of the Landes geese were lower than those of the Poland geese (9.4 vs 12.9 g/L) and their PC:PE (13.6%) and PL-polyunsaturated fatty acids (PUFA) content (25%) were decreased compared with the Poland geese (21.2 and 30%). It is likely that the higher susceptibility to fatty liver of the Landes breed involves a differential channelling of PL, resulting in a greater hepatic retention of PC and PUFA that are necessary for plasma membrane growth and cell hypertrophy.

  5. Uranium in Canada

    International Nuclear Information System (INIS)

    In 1988 Canada's five uranium producers reported output of concentrate containing a record 12,470 metric tons of uranium (tU), or about one third of total Western world production. Shipments exceeded 13,200 tU, valued at $Cdn 1.1 billion. Most of Canada's uranium output is available for export for peaceful purposes, as domestic requirements represent about 15 percent of production. The six uranium marketers signed new sales contracts for over 11,000 tU, mostly destined for the United States. Annual exports peaked in 1987 at 12,790 tU, falling back to 10,430 tU in 1988. Forward domestic and export contract commitments were more than 70,000 tU and 60,000 tU, respectively, as of early 1989. The uranium industry in Canada was restructured and consolidated by merger and acquisition, including the formation of Cameco. Three uranium projects were also advanced. The Athabasca Basin is the primary target for the discovery of high-grade low-cost uranium deposits. Discovery of new reserves in 1987 and 1988 did not fully replace the record output over the two-year period. The estimate of overall resources as of January 1989 was down by 4 percent from January 1987 to a total (measured, indicated and inferred) of 544,000 tU. Exploration expenditures reached $Cdn 37 million in 1987 and $59 million in 1988, due largely to the test mining programs at the Cigar Lake and Midwest projects in Saskatchewan. Spot market prices fell to all-time lows from 1987 to mid-1989, and there is little sign of relief. Canadian uranium production capability could fall below 12,000 tU before the late 1990s; however, should market conditions warrant output could be increased beyond 15,000 tU. Canada's known uranium resources are more than sufficient to meet the 30-year fuel requirements of those reactors in Canada that are now or are expected to be in service by the late 1990s. There is significant potential for discovering additional uranium resources. Canada's uranium production is equivalent, in

    To study the functions of prolactin receptor( PRLR) in goose,we constructed a prokaryotic expression vector exPRLR-Pet-28a( +) that contains exPRLR, the coding sequences of the whole extracellular domain of goose PRLR. Transformed into host bacteria E. Coli Roster and induced by IPTG,ex:PRLR-Pet-28a( +)expressed recombinant protein exPRLR. By immunizing rabbit with the re-combinant protein, we obtained rabbit anti-goose exPRLR polycolonal serum. Western blot assay revealed that the anti-serum recognized the recombinant protein expressed by the transformed bacteria specifically. Analyzing the proteins isolated from adult female goose tissues with the anti-serum, we found that adult geese might have at least three isoforms of PRLR with different relative molecular mass.%为深入研究鹅催乳素受体(PRLR)的功能,构建了含鹅PRLR胞外域编码序列exPRLR的原核表达质粒exPRLR-pET-28a(+),通过转化E coli Roster建立了稳定的原核表达系统,在IPTG诱导下获得了PRLR胞外域的重组exPRLR.以重组exPRLR为抗原免疫家兔,获得了兔抗鹅exPRLR的抗血清.Western blot分析证明该抗血清可特异识别由原核生物表达的重组exPRLR.进一步分析成年母鹅的组织蛋白,发现成年鹅中可能至少存在3种相对分子质量不同的PRLR蛋白异形体.

  9. Addressing Household Food Insecurity in Canada - Position Statement and Recommendations - Dietitians of Canada.

    2016-07-01

    POSITION STATEMENT It is the position of Dietitians of Canada that household food insecurity is a serious public health issue with profound effects on physical and mental health and social well-being. All households in Canada must have sufficient income for secure access to nutritious food after paying for other basic necessities. Given the alarming prevalence, severity and impact of household food insecurity in Canada, Dietitians of Canada calls for a pan-Canadian, government-led strategy to specifically reduce food insecurity at the household level, including policies that address the unique challenges of household food insecurity among Indigenous Peoples. Regular monitoring of the prevalence and severity of household food insecurity across all of Canada is required. Research must continue to address gaps in knowledge about household vulnerability to food insecurity and to evaluate the impact of policies developed to eliminate household food insecurity in Canada. Dietitians of Canada recommends: Development and implementation of a pan-Canadian government-led strategy that includes coordinated policies and programs, to ensure all households have consistent and sufficient income to be able to pay for basic needs, including food. Implementation of a federally-supported strategy to comprehensively address the additional and unique challenges related to household food insecurity among Indigenous Peoples, including assurance of food sovereignty, with access to lands and resources, for acquiring traditional/country foods, as well as improved access to more affordable and healthy store-bought/market foods in First Nation reserves and northern and remote communities. Commitment to mandatory, annual monitoring and reporting of the prevalence of marginal, moderate and severe household food insecurity in each province and territory across Canada, including among vulnerable populations, as well as regular evaluation of the impact of poverty reduction and protocols for

  10. Canada and global warming: Meeting the challenge

    International Nuclear Information System (INIS)

    Canada accounts for ca 2% of total world emissions of greenhouse gases. Carbon dioxide emissions are by far the largest greenhouse gas source in Canada, primarily from energy consumption. On a per capita basis, Canada ranks second among industrialized countries in terms of energy related carbon dioxide emissions. Canada's northern geography and climate, its export-oriented economy with energy-intensive resource industries, and its relatively small population dispersed over a wide land mass contribute to this high per-capita value. The effects of global warming induced by greenhouse gases are outlined, including a reduction in water supplies, droughts affecting agriculture and forestry, and large-scale thawing of permafrost. A national strategy to respond to global warming has been developed which includes limiting and reducing greenhouse gas emissions, preparing for potential climatic changes, and improving scientific understanding and predictive capabilities with respect to climate change. Details of this strategy are outlined, including provincial and territorial strategies in partnership with the national strategy. 11 figs., 2 tabs

    2012-01-01

    With cases now documented in every province, Lyme borreliosis (LB) is emerging as a serious public health risk in Canada. Controversy over the contribution of LB to the burden of chronic disease is maintained by difficulty in capturing accurate Canadian statistics, especially early clinical cases of LB. The use of dogs as sentinel species demon-strates that potential contact with Borrelia burgdorferi spirochetes, as detected by C6 peptide, extends across the country. Dissemination of infected ticks by migratory birds and rapid establishment of significant levels of infection have been well described. Canadian public health response has focused on identification of established populations of the tick vectors, Ixodes scapularis and I. pacificus, on the assumption that these are the only important vectors of the disease across Canada. Strains of B. burgdorferi circulating in Canada and the full range of their reservoir species and coinfections remain to be explored. Ongoing surveys and historical records demonstrate that Borrelia-positive Ixodes species are regu-larly present in regions of Canada that have previously been considered to be outside of the ranges of these species in re-cent modeling efforts. We present data demonstrating that human cases of LB are found across the nation. Consequently, physician education and better early diagnoses are needed to prevent long term sequelae. An international perspective will be paramount for developing improved Canadian guidelines that recognize the complexity and diversity of Lyme borreliosis.

    We report a novel goose parvovirus (MDGPV/PT) isolated from an affected Muscovy duck in Fujian Province, China. In this study, the NS1 sequence analyses indicated a close genetic relationship between MDGPV/PT and Muscovy duck parvovirus (MDPV) strains, although MDGPV/DY, which was isolated from a Muscovy duck in 2006 in Sichuan Province, could be divided into GPV-related groups. Phylogenetic analysis showed that except for differences in the NS1 gene, MDGPV strains PT and DY are closely related to a parvovirus that infects domestic waterfowls. This is the first demonstration of recombination between goose and Muscovy duck parvoviruses in nature, and MDGPV/PT might have led to the generation of a novel waterfowl parvovirus strain circulating in Muscovy duck flocks in China.

    A specific Polymerase Chain Reaction (PCR) has been developed for the identification of goose (Anser anser), mule duck (Anas platyrhynchos x Cairina moschata), chicken (Gallus gallus), turkey (Meleagris gallopavo), and swine (Sus scrofa domesticus) in foie gras. A forward common primer was designed on a conserved DNA sequence in the mitochondrial 12S ribosomal RNA gene (rRNA), and reverse primers were designed to hybridize on species-specific DNA sequences of each species considered. The different sizes of the species-specific amplicons, separated by agarose gel electrophoresis, allowed clear identification of goose, mule duck, chicken, turkey, and swine in foie gras. Analysis of experimental mixtures demonstrated that the detection limit of the assay was approximately 1% for each species analyzed. This genetic marker can be very useful for the accurate identification of these species, avoiding mislabeling or fraudulent species substitution in foie gras.

    From the early 1970s to the present, numerous cases of short beak and dwarfism syndrome (SBDS) have been reported in mule ducks from France. The animals showed strong growth retardation with smaller beak and tarsus. It was suggested that the syndrome was caused by goose parvovirus on the basis of serological investigation, but the causative agent has not been isolated and the disease has not so far been reproduced by experimental infection. The aim of the present study was to characterize the virus strains isolated from field cases of SBDS, and to reproduce the disease experimentally. Phylogenetic analysis proved that the parvovirus isolates obtained from SBDS of mule duck belonged to a distinct lineage of goose parvovirus-related group of waterfowl parvoviruses. The authors carried out experimental infections of 1-day-old, 2-week-old and 3-week-old mule ducks by the oral route with three different parvovirus strains: strain D17/99 of goose parvovirus from Derzsy's disease, strain FM of Muscovy duck parvovirus from the parvovirus disease of Muscovy ducks, and strain D176/02 isolated from SBDS of mule duck. The symptoms of SBDS of the mule duck could only be reproduced with the mule duck isolate (strain D176/02) following 1-day-old inoculation. Infection with a genetically different strain of goose parvovirus isolated from classical Derzsy's disease (D17/99) or with the Muscovy duck parvovirus strain (FM) did not cause any clinical symptoms or pathological lesions in mule ducks.

    Full Text Available Seafood plays an important role in the socioeconomic, gastronomy and cultural heritage of Portuguese coastal communities. In the Iberian Peninsula, the goose barnacle Pollicipes pollicipes is the intertidal biological resource most heavily exploited by man, resulting on overexploitation of stocks. In the MPA of BNR P.pollicipes harvesting is however strictly regulated, making it a good example of marine resources management. Analytical methods able to identify the origin of goose barnacle would be an important tool to help the management of the trade. For such purpose, we investigated whether P. pollicipes have site-specific differences based on its elemental microchemistry (EM, fatty acid profile (FA and capitulum shape (CS. The analysis was performed on specimens collected from 3 sites in the BNR and 7 along a 300 km stretch of the Portuguese coast. For each individual we analysed the largest lateral shell for EM using ICP-MS, the FA content of the muscle using GC-FID, and the CS using geometric morphometrics. Discriminant function analyses (DFA for both EM and FA separately provided a high reclassification success (77.6% and 99% respectively, of cross-validated cases correctly classified, while for EM combined with FA allowed for a 100% reclassification success. DFA analysis based only on CS, revealed a low classification success (29.6%. These results show that EM and FA signatures can be a powerful tool to infer goose barnacles origin. Such “fingerprinting” approach can be used to track and identify goose barnacles origin, helping in establishing an origin certificate and increasing the potential value of biological resources from Portuguese MPAs.

    A recent epizootic outbreak, in China, of duck beak atrophy and dwarfism syndrome (BADS) was investigated using electron microscopic, genetic, and virological studies, which identified a parvovirus with a greater similarity to goose parvovirus (GPV) (97% protein homology) than to Muscovy duck parvovirus (MDPV) (90% protein homology). The new virus, provisionally designated GPV-QH15, was found to be antigenically more closely related to GPV than to MDPV in a virus neutralization assay. These findings were further supported by phylogenetic analysis showing that GPV-QH15 evolved from goose lineage parvoviruses, rather than from Muscovy duck- or other duck species-related parvoviruses. In all, two genetic lineages (GPV I and GPV II) were identified from the GPV samples analyzed, and GPV-QH15 was found to be closely clustered with two known goose-origin parvoviruses (GPVa2006 and GPV1995), together forming a distinctive GPV IIa sublineage. Finally, structural modeling revealed that GPV-QH15 and the closely related viruses GPVa2006 and GPV1995 possessed identical clusters of receptor-interacting amino acid residues in the VP2 protein, a major determinant of viral receptor binding and host specificity. Significantly, these three viruses differed from MDPVs and other GPVs at these positions. Taken together, these results suggest that GPV-QH15 represents a new variant of goose-origin parvovirus that currently circulates in ducklings and causes BADS, a syndrome reported previously in Europe. This new finding highlights the need for future surveillance of GPV-QH15 in poultry in order to gain a better understanding of both the evolution and the biology of this emerging parvovirus.

    Full Text Available The Huoyan goose is famous for its high egg-laying performance and is listed as a nationally protected domestic animal by the Chinese government. To elucidate the key regulatory genes involved in Huoyan goose egg laying, RNA from ovarian tissue during the ceased and laying periods was sequenced using the Illumina HiSeq 2000 sequencing platform. More than 12 million reads were produced in ceased and laying libraries that included 11,896,423 and 12,534,799 clean reads, respectively. More than 20% of the reads were matched to the reference genome, and 23% of the reads were matched to reference genes. Genes with a false discovery rate (FDR ≤0.001 and log2ratio ≧1 or ≤-1 were characterized as differentially expressed, and 344 up-regulated and 344 down-regulated genes were classified into functional categories. Twelve genes that are mainly involved in pathways for reproduction regulation, such as steroid hormone biosynthesis, GnRH signaling pathways, oocyte meiosis, progesterone-mediated oocyte maturation, steroid biosynthesis, calcium signaling pathways, and G-protein coupled receptor signaling pathway were selected for validation by a quantitative real-time polymerase chain reaction (qRT-PCR analysis, the qRT-PCR results are consistent with the general expression patterns of those genes from the Illumina sequencing. These data provide comprehensive gene expression information at the transcriptional level that might increase our understanding of the Huoyan goose's reproductive biology.

  19. Transnational surrogacy: Canada's contradictions.

    Science.gov (United States)

    Lozanski, Kristin

    2015-01-01

    Transnational commercial surrogacy represents a form of medical tourism undertaken by intended parents who seek to hire women in other countries, increasingly often in the global South, as surrogates. While much of the scholarly literature focuses on the conditions of surrogacy within host countries, such as India, there has been limited analysis of transnational surrogacy focused upon origin countries. In this article, I build upon the scholarship that explores the impact of host country structures on transnational surrogacy, with special attention to the significance of Canadian citizenship policy through analysis of legislation and policy vis-à-vis transnational commercial surrogacy. The Canadian case demonstrates clear contradictions between the legislation and policy that is enacted domestically to prohibit commercial surrogacy within Canada and legislation and policy that implicitly sanctions commercial surrogacy through the straightforward provision of citizenship for children born of such arrangements abroad. The ethical underpinnings of Canada's domestic prohibition of commercial surrogacy, which is presumed to exploit women and children and to impede gender equality, are violated in Canada's bureaucratic willingness to accept children born of transnational commercial surrogacy as citizens. Thus, the ethical discourses apply only to Canadian citizens within Canadian geography. The failure of the Canadian government to hold Canadian citizens who participate in transnational commercial surrogacy to the normative imperatives that prohibit the practice within the country, or to undertake a more nuanced, and necessarily controversial, discussion of commercial surrogacy reinforces transnational disparities in terms of whose bodies may be commodified as a measure of gendered inequality.

    OECD's comprehensive 2004 report on Canada's environmental policies and programmes systematically examines policy related to air, water, and nature/biodiversity as well as the interface between environmental policy and economic policy, social policy, and specific sectors. It finds that while Canada has made satisfactory progress since 1985, there are still significant challenges, and the report makes specific recommendations for more use of economic instruments and use of the polluter and user pays principles, rationalising water governance, strengthening nature protection, reducing energy intensity, implementing climate change policies, reviewing environmentally related taxes, and implementing marine and aid commitments. Coal provides about 20% of Canada's electric power. Most direct subsidisation of the fossil fuel supply industries (upstream oil, gas and coal) has been reduced. The report recommends subsidies to the mining industry for exploration should also be phased out. Recent measurements indicate emissions of mercury are increasing, mainly due to long-range transboundary air pollution from coal-burning plants. 42 figs., 24 tabs.

    It has been demonstrated, for many inherited diseases, that historical events have shaped the various regional gene pools of Eastern Canada. In so doing, it has given rise to the increased prevalence of some rare diseases due, to founder effects. The following neurogenetic disorders were first identified in patients from Eastern Canada: AOA-2, Arsacs, HSN-2, Arca-1, HMSN/ACC and Arsal. The population of Eastern Canada, we are convinced, will still allow the identification of new rare forms of hereditary ataxias, spastic parapareses and neuropathies as well as contribute to the uncovering of their mutated genes. We have summarized our current knowledge of the various hereditary ataxias, spastic parapareses and neuropathies in Eastern Canada. The study of the more common and homogenous features of these diseases has been largely completed.

    2016-02-01

    The structure and composition of the eggshells of two commercial species (guinea fowl and greylag goose) have been studied. Thin sections and scanning electron microcopy show the similarity of the overall structure, but the relative thickness of the layers differs in these two taxa. Atomic force microscopy shows that the different layers are composed of rounded, heterogeneous granules, the diameter of which is between 50 and 100 nm, with a thin cortex. Infrared data and thermogravimetric analyses show that both eggshells are made of calcite, but differing on the quality and quantity when the organic component is considered. Chemical maps show that chemical element distribution is not uniform within a sample, and differs between the species, but with low magnesium content. Electron back scattered diffraction confirms the eggshells are calcite, but the microtexture strongly differs between the two species. Based on the chemical-structural differences, a species-specific biological control on the biomineralization is found, despite the rapid formation of an eggshell. Overall results indicate that to estimate the quality of eggshells, such as resistance to breakage, is not a straightforward process because of the high complexity of avian eggshell biomineralization.

    The major capsid protein VP2 of goose parvovirus (GPV) expressed using a baculovirus expression system (BES) assembles into virus-like particles (VLPs). To optimize VP2 gene expression in Sf9 cells, we converted wild-type VP2 (VP2) codons into codons that are more common in insect genes. This change greatly increased VP2 protein production in Sf9 cells. The protein generated from the codon-optimized VP2 (optVP2) was detected by immunoblotting and an indirect immunofluorescence assay (IFA). Transmission electron microscopy analysis revealed the formation of VLPs. These findings indicate that optVP2 yielded stable and high-quality VLPs. Immunogenicity assays revealed that the VLPs are highly immunogenic, elicit a high level of neutralizing antibodies and provide protection against lethal challenge. The antibody levels appeared to be directly related to the number of GP-Ag-positive hepatocytes. The variation trends for GP-Ag-positive hepatocytes were similar in the vaccine groups. In comparison with the control group, the optVP2 VLPs groups exhibited obviously better responses. These data indicate that the VLPs retained immunoreactivity and had strong immunogenicity in susceptible geese. Thus, GPV optVP2 appears to be a good candidate for the vaccination of goslings.

    In 2015, novel duck-origin goose parvovirus-related parvovirus (N-GPV) infection progressively appeared in commercial Cherry Valley duck flocks in North China. Diseased ducks were observed to have beak atrophy and dwarfism syndrome (BADS). A previous study showed that a high seropositive rate for N-GPV indicated a latent infection in most breeder duck flocks. To investigate this possibility in hatching eggs collected from N-GPV-infected breeder ducks, 120 eggs were collected at various stages of embryonic development for viral DNA detection and an N-GPV-specific antibody test. N-GPV DNA was present in nine hatching eggs, eleven duck embryo and eight newly hatched ducklings. Of the newly hatched ducklings, 58.33% (21/36) were seropositive. Further, two isolates were obtained from a 12-day-old duck embryo and a newly hatched duckling. N-GPV infection did not reduce the fertilization rate and hatchability. These results indicate possible vertical transmission of N-GPV and suggest that it may be transmitted from breeder ducks to ducklings in ovo. PMID:26890433

    One trial was conducted to study nutrition digestibility of Euchsaena mexicana Schrad (EMC) diets for Wulong Goose.Thirty-two geese of 9 months old were selected and divided into four groups randomly, with eight geese in each group.Four groups were fed with the isocaloric and isonitrogenous diets of different EMC contents (12, 19, 25 and 31%),respectively. The results showed that, as dietary EMC increased, dry matter (DM) digestibility was decreased significantly,meanwhile the digestibility of crude fiber (CF), neutral detergent fiber (NDF) and acid detergent fiber (ADF) increased significantly (P<0.05). The ratio of apparent essential amino acid (EAA) digestibility (except Leu) among the four groups had significant difference (P<0.01). the content of NH3-N in feces dropped (P>0.05). There were no significant differences in net protein utilization (NPU), N apparent digestibility, N deposition and Ca apparent digestibility in different groups (P>0.05). The apparent digestibility of P in different groups elevated, while there was significant difference between group D and A (P<0.01), and there was significant difference between group D and B (P<0.05).

  7. Immigration in two federations: Canada and Australia.

    1988-03-01

    The need for increasingly widespread application of a policy or program, settlement, and multiculturalism is urgent in both Canada and Australia. For both countries there is a clear pattern of coalescence and divergence and the distinct growth of immigration as a federal function. While Australia has strengthened federal functions in a area of increasingly geo-political need, Canada is moving towards a looser model of federalism. By 1918 both countries were strengthening their federal functions in immigration as discussions within the British Empire on the recommendations of the 1917 Dominions Royal Commission took root. Both countries were interested in agricultural immigration and land settlement. The Great Depression caused a major reduction in population growth rates. From 1933-1948 Canada had a poor record of providing sanctuary for Jews. In Australia, however, Jewish voluntary agencies were aiding the reception of refugees by 1937. The 1st permanent embodiment of commonwealth jurisdiction over immigration was the establishment of an Immigration Branch within the Department of Interior around 1938. Australia needed extra population for defense. The major structural link between government and the immigrant communities was through the Good Neighbor Movement, which began on a nationwide basis in 1950. Both Canada and Australia are major receiving countries for refugees. In 1973 Australia reached the position of effective, practical nondiscrimination achieved by Canada in 1967. Prime Minister Trudeau's policy was multiculturalism within a framework of bilingualism. By 1978 Australia had a new federalism policy, which in all areas concerned with immigrants, refugees and ethnicity, rationalized resources allocation and imposed a political philosophy. The foci of multiculturalism in Australia are 1) community languages; 2) creation of a tolerant, non-discriminatory society; and 3) equity and participation. In 1978 Australia specified population replacement and

  8. Canada's disposal concept

    International Nuclear Information System (INIS)

    A concept for the safe and permanent disposal of nuclear fuel wastes from Canada's CANDU reactors has been developed by Atomic Energy of Canada Ltd. (AECL). The waste would be placed in an engineered disposal vault 500 to 1000 m below the surface in plutonic rock of the Canadian Shield. The multiple barriers to retain the waste and retard the release of radioactivity would be the waste form, the containers, buffer and backfill, and the rock overlying the vault. Numerous research programmes have been carried out to develop the technology for the concept. These include work on materials corrosion and failure mechanisms to assess the performance of the used fuel containers. Predictive modelling has shown that more than 97% of ASTM Grade 2 titanium containers will retain their integrity, even under pessimistic assumptions, for 1200-6000 years after emplacement, and even longer times may be achieved with other grades of titanium or copper. Other research has been aimed at vault sealing, at site characterization for an underground research laboratory and at the development of a methodology for assessing radiological and environmental effects after closure of the facility. A review of the safety and environmental impacts of the concept is now being carried out by an independent panel appointed by the government. (2 figures, 3 references) (UK)

    This paper provided an outline of Canada's Clean Air Act and examined some of the regulatory changes that will occur as a result of its implementation. The Act is being introduced to strengthen the legislative basis for taking action on reducing air pollution and GHGs, and will allow the government to regulate both indoor and outdoor air pollutants and GHGs. The Act will require the Ministers of the Environment and Health to establish national air quality objectives, as well as to monitor and report on their attainment. The Canadian Environmental Protection Act will be amended to enable the government to regulate the blending of fuels and their components. The Motor Vehicle Fuel Consumption Standards Act will also be amended to enhance the government's authority to regulate vehicle fuel efficiency. The Energy Efficiency Act will also be expanded to allow the government to set energy efficiency standards and labelling requirements for a wider range of consumer and commercial products. The Act will commit to short, medium and long-term industrial air pollution targets. Regulations will be proposed for emissions from industry; on-road and off-road vehicles and engines; and consumer and commercial products. It was concluded that the Government of Canada will continue to consult with provinces, territories, industries and Canadians to set and reach targets for the reduction of both indoor and outdoor air pollutants and GHG emissions. 6 figs

  10. Energy in Canada

    International Nuclear Information System (INIS)

    Canada's historical energy consumption, its current consumption and its likely requirements by the turn of the century are reviewed. It is estimated that at least 50% more energy will be required in the year 2000 than is consumed now, assuming a minimum 2% growth rate in primary energy consumption. Both non-renewable and renewable energy resources are examined in the light of these future energy requirements and the need to substitute alternative energy sources for conventional oil in various end uses. The comparative risks involved in energy production are also reviewed. Most of the increase in energy consumption and the substitution of oil over the next 20 years is likely to be met by conventional energy sources, since indigenous reserves are extensive and the relevant technologies well-established. Coal, nuclear and hydro reserves could cover the increase in energy demand until well into the next century, and natural gas reserves are sufficient to bridge the gap during conversion from oil to other energy sources. Nuclear power using advanced fuel cycles and oil from tar sands offer Canada long-term security. The penetration of unconventional energy sources is likely to be relatively small during the next 20 years. However, the most promising may become significant in the next century. (author)

  11. Climate change and the increasing impact of polar bears on bird populations

    Full Text Available The Arctic is becoming warmer at a high rate, and contractions in the extent of sea ice are currently changing the habitats of marine top-predators dependent on ice. Polar bears (Ursus maritimus depend on sea ice for hunting seals. For these top-predators, longer ice-free seasons are hypothesized to force the bears to hunt for alternative terrestrial food, such as eggs from colonial breeding birds. We analyzed time-series of polar bear observations at four locations on Spitsbergen (Svalbard and one in east Greenland. Summer occurrence of polar bears, measured as the probability of encountering bears and the number of days with bear presence, has increased significantly from the 1970/80s to the present. The shifts in polar bear occurrence coincided with trends for shorter sea ice seasons and less sea ice during the spring in the study area. This resulted in a strong inverse relationship between the probability of bear encounters on land and the length of the sea ice season. Within ten years after their first appearance on land, polar bears had advanced their arrival dates by almost 30 days. Direct observations of nest predation showed that polar bears may severely affect reproductive success of the barnacle goose (Branta leucopsis, common eider (Somateria mollissima and glaucous gull (Larus hyperboreus. Nest predation was strongest in years when the polar bears arrived well before hatch, with more than 90% of all nests being predated. The results are similar to findings from Canada, and large-scale processes, such as climate and subsequent habitat changes, are pinpointed as the most likely drivers in various parts of the Arctic. We suggest that the increasing, earlier appearance of bears on land in summer reflects behavioral adaptations by a small segment of the population to cope with a reduced hunting range on sea ice. This exemplifies how behavioral adaptations may contribute to the cascading effects of climate change.

    Full Text Available Canada faces health care challenges common to all industrialized countries – how to ensure timely access to high quality care, close to home, at an affordable cost. Addressing these challenges is complicated by interjurisdictional variation in both how health care is managed and delivered, and in health outcomes. Canada can be described as a non-system of 10 provincial and three territorial health insurance plans which mandate publicly-funded coverage for medically necessary hospital and physician services, based upon common principles and shaped by a federal governance structure that affords substantial power and autonomy to the provinces/territories over matters of health and health care. This article first examines the structural context of the health care system in Canada, including the range of services publicly funded, the public-private mix, and the complexities of current governance arrangements. It then discusses several issues affecting health policy reform: costs versus access; questions of sustainability, quality, and performance; human resources capacity; and the provision of public and population health services.

    Waterbirds breeding on the Mongolian Plateau in Central Asia must find suitable wetland areas for nesting in a semiarid region characterized by highly variable water conditions. The first systematic nesting study of a waterbird dependent on this region for breeding was conducted on the Bar-headed Goose (Anser indicus). The purpose of this study was to document Bar-headed Goose nesting locations, characterize nests and nesting strategies, and estimate daily nest survival (n = 235 nests) from eight areas of west-central Mongolia across three summers (2009–2011) using a modified Mayfield estimator. Bar-headed Goose daily nest survival ranged from 0.94 to 0.98, with a 3-year average nest success of 42.6% during incubation. Bar-headed Geese were found to primarily nest on isolated pond and lake islands as previously reported, but were also documented regularly, though less frequently, along rocky cliffs in several regions of west-central Mongolia. Daily nest survival was higher for cliff nests than for island nests. Information-theoretic models indicated that nest survival decreased with nest age and varied annually with changing environmental conditions. Results of this study suggest that while Bar-headed Geese primarily rely on nesting island sites these sites may be more susceptible to anthropogenic disturbance and predation events influenced by seasonal variation in environmental conditions, and that higher daily nest survival values documented for the less frequent cliff nest strategy may provide an important alternative strategy during poor island nest success years. Thus, conservation efforts for this and other waterbird species in the semiarid region should be focused on conserving nesting islands and protecting them from disturbance in areas of high livestock densities experiencing a rapidly warming climate.

    Hemorrhagic nephritis enteritis of geese (HNEG) is an epizootic viral disease caused by infection with goose hemorrhagic polyomavirus (GHPV) that affects domestic geese. This study describes the epizootic analysis, laboratory diagnosis, and molecular characterization of GHPV isolates associated with HNEG cases in Poland. HNEG symptoms persisted in infected flocks for 2 wk with a 32% mortality rate. Primary gross lesions included hemorrhaging of the kidneys, intestines, and lungs. Histopathologic examination confirmed HNEG and identified that the causative agent was similar to other GHPV isolates and identical to the Toulouse 2008 isolate.

    This paper examines the distribution of gambling dollars in Nova Scotia, Saskatchewan and Canada and studies the impact of this spending on households. We focus first on how gambling expenditures are related to the level and source of household income as well as to other demographic characteristics such as age, education, household composition, geographical area, and sources of income. Next we analyze how gambling expenditures are distributed among those households that gamble. We show how expenditure patterns differ in the intensity of gambling as measured by the proportion of household income or total amount of dollars spent on gambling. Then we study the affects that gambling has on spending on household necessities, changes in net worth, retirement savings and household debt. Finally we determine whether gambling expenditures act as a substitute or a complement to other recreational spending on entertainment products and services. Throughout the paper we offer a comparative analysis of provincial and national data. PMID:15353922

The studies identified clear differences in tissue levels of Hg, Pb and Cd between different collection areas. There is evidence to support Hg poisoning as the cause of death in at least one otter along this river system. The studies emphasize the potential interactions of toxic chemicals with each other and with natural stresses (e.g. cold, starvation, disease. More research is required along these lines since simultaneous exposure to more than one chemical and other stresses is more typical of conditions in the wild.

    In April 2014, poor fertility in a major commercial goose breeder operation in California triggered the submission of six live affected Toulouse ganders ( Anser anser ) to the California Animal Health and Food Safety Laboratory, Turlock branch (University of California-Davis). Toulouse were principally affected among all breeds, and their egg fertility dropped from 65.7% to less than 33.9% in the first 40 days of the 2014 breeding season. The flock consisted of 410 adult birds, 90 males and 320 females, between 2 and 5 yr of age. Inspection of the flock revealed that 44.4% of the Toulouse ganders had severe phallic deformities that prevented them from mating. At postmortem examination, severe yellowish fibrocaseous exudate disrupted the architecture of the phallus and occasionally produced fistulating tracts through the wall of the organ. Microscopically, multifocal lymphoid nodules were noted in the mucosa and submucosa of the phallus and were associated with extensive granulomatous reaction, intralesional bacteria, and spermatozoa. Mycoplasma spp. were isolated from the phallus of affected and nonaffected birds, and PCR protocols targeting the 16S-23S ribosomal RNA intergenic spacer regions and the RNA polymerase beta subunit gene were performed to identify the isolates. Three distinct species were identified on sequencing and analysis using the National Center for Biotechnology Information basic local alignment search tool: Mycoplasma cloacale , Mycoplasma anseris , and an unknown novel Mycoplasma sp. Additionally, Pasteurella multocida , in combination with other bacteria, was also isolated from the phallic lesions and identified as serotype 3 with a DNA profile of 1511 (National Veterinary Service Laboratory). This is the first report of these Mycoplasma spp. and other bacteria associated with reproductive disease in ganders in the United States. PMID:27309284

  2. Provenance of geogenic arsenic in the Goose River basin, Maine, USA

    Occurrences of arsenic (As) are sporadic in drinking water from many wells in mid-coastal Maine. This is particularly the case where water supplies are pumped from fractured igneous and metamorphic bedrock. Although health risk-based As contamination levels are lowered, it is likely that the provenance of trace As concentrations will need to be scrutinized. Approximately 33% of wells sampled in the Goose River ground-watershed had at least one occurrence of 10 µg l-1 As. Geologic mapping in combination with the rock petrology and mineral chemistry were important in deciphering probable local source areas for arsenic. Median whole rock As is greater than 39 mg kg-1 in the Bucksport Formation and anatectic granitoids of the Waldoboro Pluton Complex. 34S isotopic composition of arsenian pyrites indicate that local areas of anomalous arsenic-bearing, transported soils are not the source of trace As in groundwater, but, instead, the As is derived from oxidation processes in the fractured bedrock along the western margin of the ground-watershed. In groundwater, the As3+/As5+ ratios ranged from 0.01 to 4.45 and were inconsistent spatially and temporally. Although it is probable that the stability field in most groundwater supplies is HAsO4 2-, arsenic speciation is not necessarily an aid to predicting transport. Instead an isotopic evaluation of associated groundwater SO4 2- clearly indicates a consistent correlation of elevated As with enriched δ34SSO4. The δ34SSO4 ranges of +4.05 to +4.61‰ may be characteristic of local oxidation in the fractured groundwater flow systems. Potential areas of geogenic As transport may be predictable.

  3. Two goose-type lysozymes in Mytilus galloprovincialis: possible function diversification and adaptive evolution.

    Directory of Open Access Journals (Sweden)

    Qing Wang

    Full Text Available Two goose-type lysozymes (designated as MGgLYZ1 and MGgLYZ2 were identified from the mussel Mytilus galloprovincialis. MGgLYZ1 mRNA was widely expressed in the examined tissues and responded sensitively to bacterial challenge in hemocytes, while MGgLYZ2 mRNA was predominately expressed and performed its functions in hepatopancreas. However, immunolocalization analysis showed that both these lysozymes were expressed in all examined tissues with the exception of adductor muscle. Recombinant MGgLYZ1 and MGgLYZ2 could inhibit the growth of several Gram-positive and Gram-negative bacteria, and they both showed the highest activity against Pseudomonas putida with the minimum inhibitory concentration (MIC of 0.95-1.91 µM and 1.20-2.40 µM, respectively. Protein sequences analysis revealed that MGgLYZ2 had lower isoelectric point and less protease cutting sites than MGgLYZ1. Recombinant MGgLYZ2 exhibited relative high activity at acidic pH of 4-5, while MGgLYZ1 have an optimum pH of 6. These results indicated MGgLYZ2 adapted to acidic environment and perhaps play an important role in digestion. Genomic structure analysis suggested that both MGgLYZ1 and MGgLYZ2 genes are composed of six exons with same length and five introns, indicating these genes were conserved and might originate from gene duplication during the evolution. Selection pressure analysis showed that MGgLYZ1 was under nearly neutral selection while MGgLYZ2 evolved under positive selection pressure with three positively selected amino acid residues (Y(102, L(200 and S(202 detected in the mature peptide. All these findings suggested MGgLYZ2 perhaps served as a digestive lysozyme under positive selection pressure during the evolution while MGgLYZ1 was mainly involved in innate immune responses.

    Understanding the implications of climate change on northern Canada requires a background about the size and diversity of its human and biogeophysical systems. Occupying an area of almost 40% of Canada, with one-third of this contained in Arctic islands, Canada's northern territories consist of a diversity of physical environments unrivaled around the circumpolar north. Major ecozones composed of a range of landforms, climate, vegetation, and wildlife include: Arctic, boreal and taiga cordillera; boreal and taiga plains; taiga shield; and northern and southern Arctic. Although generally characterized by a cold climate, there is an enormous range in air temperature with mean annual values being as high as -5 deg C in the south to as low as -20 deg C in the high Arctic islands. A similar contrast characterizes precipitation, which can be >700 mm y-1 in some southern alpine regions to as low as 50 mm y-1 over islands of the high Arctic. Major freshwater resources are found within most northern ecozones, varying from large glaciers or ice caps and lakes to extensive wetlands and peat lands. Most of the North's renewable water, however, is found within its major river networks and originates in more southerly headwaters. Ice covers characterize the freshwater systems for multiple months of the year while permafrost prevails in various forms, dominating the terrestrial landscape. The marine environment, which envelops the Canadian Arctic Archipelago, is dominated by seasonal to multiyear sea ice often several meters thick that plays a key role in the regional climate. Almost two-thirds of northern Canadian communities are located along coastlines with the entire population being just over 100 000. Most recent population growth has been dominated by an expansion of nonaboriginals, primarily the result of resource development and the growth of public administration. The economies of northern communities, however, remain quite mixed with traditional land

    The complete primary structure of the major component myoglobin from the goose-beaked whale, Ziphius cavirostris, was determined by specific cleavage of the protein to obtain large peptides which are readily degraded by the automatic sequencer. Over 80% of the amino acid sequence was established from the three peptides resulting from the cleavage of the apomyoglobin at its two methionine residues with cyanogen bromide along with the four peptides resulting from the cleavage with trypsin of the citraconylated apomyoglobin at its three arginine residues. Further digestion of the central cyanogen bromide peptide with S. aureus strain V8 protease and the 1,2-cyclohexanedione-treated central cyanogen bromide peptide with trypsin enabled the determination of the remainder of the covalent structure. This myoglobin differs from the cetacean myoglobins determined to date at 12 to 17 positions. These large sequence differences reflect the distant taxonomic relationships between the goose-beaked whale and the other species of Cetacea the myoglobin sequences of which have previously been determined.

    The use of near-infrared reflectance spectroscopy (NIRS) on a meat product is described in this report. The aim of the study was to develop calibration equations to predict the chemical composition of goose fatty liver (foie gras) with lipid contents greater than 40% of the fresh pate. Spectra of 52 foie gras samples were collected in the visible and NIR region (400 to 2,498 nm). Calibration equations were computed for DM, CP, lipids and fatty acids using modified partial least-squares regression. R2 values were high for the total lipid content (0.805) and DM (0.908) but were low for ash (0.151) and relatively low for protein content (0.255). For the major fatty acids, R2 ranged from 0.886 for palmitic acid to 0.988 for oleic acid. Oleic acid, the main fatty acid of the liver, and the stearic acid had higher R2 values than the less represented fatty acids. This study suggests that the NIRS technique can be used to predict lipid content and the fatty acid composition of goose fatty livers, but calibration must be built on a larger number of samples to generate accurate predictions.

    Two hundred and eighty-eight Wulong geese of fast-growth lines were selected to be fattened respectively in netting bed, then divided into eight groups with three replications in each group. The diets contained different contents of Ca and P to determine the best level for the early growth of Wulong goose. The result suggested that, during the early period, the proportion of Ca and NPP (non-Phytate Phosnhorus) had significant influence on its growth (P<0.05), when the dietary level of Ca was 0.65% and NPP was 0.30% (the proportion of Ca and NPP was 2.17:1), the liveweight gain was higher,so were the eviscerated ratio and eviscerated weight with giblet ratio, feed/gain (F/G) and alkaline phosphatase (AKP) activity at four weeks were lower. The Wulong goose grew well at the proportion between 1.88:1 and 2.50: 1, and grew worst at 1.38:1.

    Obstetric medicine is a growing area of interest within internal medicine in Canada. Canadians continue to travel broadly to obtain relevant training, particularly in the United Kingdom. However, there is now a sufficient body of expertise in Canada that a cadre of 'home-grown' obstetric internists is emerging and staying within Canada to improve maternity care. As this critical mass of practitioners grows, it is apparent that models of obstetric medicine delivery have developed according to local needs and patterns of practice. This article aims to describe the state of obstetric medicine in Canada, including general internal medicine services as the rock on which Canadian obstetric medicine has been built, the Canadian training curriculum and opportunities, organisation of obstetric medicine service delivery and the future.

    This article provides information about the prevalence and impact of epilepsy, based on the 2010 and 2011 Canadian Community Health Surveys, the 2011/2012 Survey of Neurological Conditions in Institutions in Canada, and the 2011 Survey on Living with Neurological Conditions in Canada. An estimated 139,200 Canadians had epilepsy. Among the household population, epilepsy was generally diagnosed before age 30 (75%). For the majority of these people (64%), epilepsy was their only neurological condition. People with epilepsy were more than twice as likely to have been diagnosed with a mood disorder, compared with the general population (17% versus 7%), and eight times as likely to experience incontinence (34% versus 4%). Overall, an estimated 18% reported that their life was affected quite a bit or extremely by epilepsy; 44% felt that their life was impacted a little bit or moderately; and 39% felt that their life was not impacted at all. This study examined the impact of epilepsy on interactions with others, sleep, driving, education, and employment. PMID:27655169

    In 2011, Canada's business sector multifactor productivity (MFP) index, as estimated by Statistics Canada, was below that for 1977, a third of a century earlier. Over these years, public policies were enacted to try to improve Canada's productivity. Yet the nation's MFP continued to fall, relative to both the past and Canada's main trading partners. Policymakers and business decision makers need to know whether Canada's MFP statistics accurately reflect the nation's productivity. We argue tha...

  15. Funding Long-Term Care in Canada: Issues and Options.

    Science.gov (United States)

    Adams, Owen; Vanin, Sharon

    2016-01-01

    Canada's aging population is likely to result in increased health and long-term care (LTC) costs. It is estimated that between 2012 and 2046, LTC cost liability could reach almost $1.2 trillion. Many Canadians are unaware of the potential burden of LTC expenditures, and there is no consensus on who should pay for them. There are four possible options: (1) general tax revenues; (2) social insurance (employer/employee contributions); (3) private purchase of LTC insurance; and (4) private savings. This paper reviews these options as they have materialized to date in Canada and other countries. Despite the growing acuity of this issue, it seems unlikely that a universal, publicly funded approach to LTC will emerge in Canada. It is clear that federal and provincial/territorial governments must continue to explore policy options for LTC funding including public education, prevention and mitigation strategies and provision for tax-sheltered savings specifically for LTC.

  16. SCWR Concept in Canada

    International Nuclear Information System (INIS)

    AECL is designing the Canadian SCWR concept, which has evolved from the well-established pressuretube type CANDU® reactor. The Canadian SCWR is designed to produce electrical energy as the main product, plus process heat, hydrogen, industrial isotopes, and drinking water (through the desalination process) as supplementary products, all within a more compact reactor building. Another potential application of the available co-generated process heat is the extraction and refining of oil sands, which is presently achieved using co-generation with natural gas turbines and process heat. The extraction and upgrading process requires: thermal power to lower the viscosity and extract the oil; electric power for separation and refining equipment; and hydrogen gas for upgrading the oil product prior to transport. A National Program has been established in Canada to support R&D studies for the Canadian SCWR design. It covers key areas of interest (such as thermal hydraulics, safety, materials, and chemistry) to participants in the Generation-IV International Forum (GIF) SCWR designs. Results generated from the program are contributed to the GIF SCWR project management boards (PMBs). For example, heat transfer correlations have been derived using experimental data primarily obtained from fossil-plant related studies (which were started as early as 1930s. Materials and chemistry studies have evolved from operating experience of fossil-fired power plants to a) develop, and perform targeted testing of, materials for key components, in particular in-core reactor components that will be exposed to conditions not encountered in a fossil-fired boiler (such as irradiation and water radiolysis), and b) develop a suitable water chemistry to minimize corrosion and corrosion product transport

  17. Child maltreatment in Canada: an understudied public health problem.

    Child maltreatment is a major public health problem associated with impairment in childhood, adolescence, and extending throughout the lifespan. Within Canada, high-quality child maltreatment studies have been conducted and are critical for informing prevention and intervention efforts. However, compared to other parts of the world (e.g., United States, United Kingdom, the Netherlands, and Mexico), the number of studies conducted in Canada is far fewer and the data used to study this important public health problem are less diverse. Importantly, to date, representative data on child maltreatment from the general population at the national level in Canada do not exist. This means that many questions regarding child maltreatment in Canada remain unanswered. To advance our understanding of child maltreatment in Canada and to make significant strides towards protecting Canadian children and families, research using Canadian data is essential. To begin to meet these important public health goals, we need to invest in collecting high-quality, nationally representative Canadian data on child maltreatment. Solutions for the barriers and challenges for the inclusion of child maltreatment data into nationally representative Canadian surveys are provided.

    Full Text Available Background and objectives. Inuit populations may be at increased risk for experiencing poor nutrition or hunger due to limited access and availability to food. The prevalence and correlates of parental perceptions of hunger among a nationally representative sample of Inuit children in Canada have not yet been reported. Design. Data are from the 2006 Aboriginal Children's Survey (ACS. Sociodemographic information, dietary behaviours and hunger status were parent-reported via a household interview for Inuit children aged 2–5 years (n=1,234. Prevalence of hunger was calculated among Inuit children by sociodemographic factors and by dietary behaviours. In addition, a multivariate logistic regression model was conducted to determine factors associated with parental perception of ever experiencing hunger. Results. The prevalence of Inuit children in Canada aged 2–5 years ever experiencing hunger was 24.4%. Children who were reported to have experienced hunger consumed milk and milk products (p<0.001; fish, eggs and meat (p<0.05; fruits (p<0.001; and vegetables (p<0.001 significantly less often than never-hungry children. Fast food and processed foods, soft drinks and juice, and salty snacks, sweets and desserts were consumed as often as never-hungry children (all p>0.05. The majority (81% of Inuit parents/guardians of ever-hungry children sought help from family or friends. Factors associated with an increased likelihood of experiencing hunger include sociodemographic characteristics (such as income and household size, living in an Inuit region and living in a community with cultural activities. Conclusion. About 1 in 4 Inuit children were reported by their parents to have experienced hunger, and hunger was associated with region, sociodemographic and community factors. Future research could further examine the impact of ever experiencing hunger on the health status of Inuit children and their families in Canada.

    Milot, Jean

    2010-06-01

    The author retraces the history of trachoma in Canada. The numerous articles in Canadian medical journals from the middle of the 18th to the middle of the 19th century show the remarkable contribution of Canadian ophthalmologists. The clinical symptoms and signs followed by the etiology and the different modes of treatment are reviewed. The presence and prevention of trachoma in Canada, ranging from Montreal to Toronto, also in Halifax with the arrival of the transatlantic immigrants, as well as those reaching the western provinces of Canada are described. How the Canadian Department of Health belatedly introduced a prevention campaign only after a widespread dissemination of trachoma across the country is also examined.

    Scallop shell powder produced by calcination process - the average diameter of the powder particles being 20 µm (SSP) - was further ground into nano-sized particles, with average diameter of 500 nm, here designated CaO-Nano. Solution of CaO-Nano could inactivate avian influenza virus within 5 sec, whereas the solution of SSP could not even after 1 hr incubation. CaO-Nano solution could also inactivate Newcastle disease virus and goose parvovirus within 5 sec and 30 sec, respectively. The virus-inactivating capacity (neutralizing index: NI>3) of the solution was not reduced by the presence of 20% fetal bovine serum. CaO-Nano solution seems to be a good candidate of materials for enhancement of biosecurity in farms.

  2. Impacts of the Snake River drawdown experiment on fisheries resources in Little Goose and Lower Granite Reservoirs, 1992

    1992-09-01

    In March 1992, the US Army Corps of Engineers initiated a test to help evaluate physical and environmental impacts resulting from the proposed future drawdown of Snake River reservoirs. Drawdown would reduce water levels in Snake River reservoirs and is being proposed as a solution to decrease the time it takes for salmon and steelhead smolts to migrate to the ocean. The Pacific Northwest Laboratory evaluated impacts to specific fisheries resources during the drawdown experiment by surveying Lower Granite Reservoir to determine if fall chinook salmon (Oncorhynchus tshawytscha) spawning areas and steelhead (0. mykiss) access to tributary creeks were affected. In addition, shoreline areas of Little Goose Reservoir were monitored to evaluate the suitability of these areas for spawning by fall chinook salmon. Relative abundance of fish species in nearshore areas was also determined during the drawdown, and stranded resident fish and other aquatic organisms were observed.

  3. Effects of Water Levels on Productivity of Canada Geese in the Northern Flathead Valley, 1984 Annual Report.

    Casey, Daniel

    1985-02-01

    Operation of Hungry Horse Dam on the South Fork Flathead River causes sporadic level fluctuations along the main stem Flathead River. Seasonal water level fluctuations and substantial habitat losses have occurred as a result of construction and operation of Kerr Dam, which regulates Flathead Lake. These fluctuations may impact goose populations through flooding or erosion of nesting and brood-rearing habitats, and increased susceptibility of nests and young to predation. The number, location, and success of goose nests were determined through pair surveys and nest searches. Counts of indicated pairs suggest there were 73-125 occupied nests in the study area; 44 were located in 1984. Twenty were island ground nests, 19 were tree nests, and 5 were on man-made structures. Hatching success was 76 percent. Sixty-one percent of all nests were in deciduous forest habitat; 87 percent were on riparian bench or island landforms. Seventy-four percent of all nests were within 5 m of the seasonal high water mark (HWM) and 85 percent of ground nests were 1 m or less above the HWM. Production, habitat use, and distribution of broods were documented through aerial, boat, ground, and observation tower surveys. 28 refs., 10 figs., 4 tabs.

  5. The Class of 1989 and physician supply in Canada

    Science.gov (United States)

    Ryten, E; Thurber, A D; Buske, L

    1998-01-01

    BACKGROUND: "The Class of 1989" is a study of 1722 people who were awarded an MD degree by a Canadian university in 1989. This paper reports on migration, specialty choices and patterns of post-MD training in order to assess the contribution of the graduating cohort to the physician workforce of Canada. METHODS: A longitudinal study was conducted over 7 years after graduation to trace the current location, the post-MD training history and the professional activity of the graduating cohort. Several medical professional and educational associations in Canada and the United States provided year-by-year information on field and location of post-MD training, certification achieved, whether in practice and location of practice through to spring 1996. Information from all sources was linked to a list of 1989 medical school graduates. RESULTS: From entry to medical school through to 7 years after graduation the cohort was diminished by about 16%. The main reason for loss was migration to other countries: 193 graduates (11.2%) were outside Canada in 1995-96. Internal migration was extensive also; for example, by 1995-96 relatively few of the graduates were located in Newfoundland or Saskatchewan. Of the 1516 graduates active in Canada in 1995-96, 878 (57.9%) were in general practice/family medicine, and only 638 (42.1%) were practising or training in a specialty. INTERPRETATION: The "yield" of the Class of 1989 for Canada's physician workforce is insufficient to meet annual physician inflows from Canadian sources to serve population growth and to replace retiring or emigrating physicians. As output from Canada's medical schools drops even further, the gap between requirements and supply will grow even wider. PMID:9538850

  6. [Linguistic minorities in Canada and health].

    Bouchard, Louise; Desmeules, Martin

    2013-10-01

    Official language minorities (Francophones outside of Quebec and Anglophones in Quebec) make up about 6.4% of the Canadian population. Even though the Canadian constitution gives legal equality status to French and English, there is still room to ask if this equality is maintained in the health sector. In other words, do Francophone and Anglophone communities of Canada have the same health profiles regardless of their minority or majority status? Do they have access to the same health services and in the same conditions? The objective of this paper is to identify the health issues associated with belonging to a linguistic minority. Our research allows us to highlight the social and health disparities that can be attributed to belonging to a minority. In the Canadian context, which has two official languages, an equitable health policy will have to take into consideration language as a determinant of health. PMID:24289938

  7. Canada's commitment to nuclear technology

    International Nuclear Information System (INIS)

    This paper gives a broad update on all facets of the Canadian nuclear industry and demonstrates Canada's continuing commitment to nuclear technology. Canada has developed a global leadership position in nuclear technology for power generation, uranium production and isotope supply. This commitment is being further enhanced by successes in international markets with Candu technology, new uranium mine developments in our province of Saskatchewan, and expanding isotope capabilities including the construction of two new production reactors. Korea's economy is benefiting through collaboration with Canada's leading nuclear companies, both in Korea and Canada. These collaborations have the potential to expand considerably with the implementation of the Kyoto Framework Convention on Climate Change and the anticipated increased demand for new nuclear power generation installations in all major global markets. Much has been publicized about the situation surrounding Ontario Hydro Nuclear and its nuclear recovery program. This paper gives the background and highlights the actions within Ontario and Ontario Hydro designed to ensure the long term recovery of all twenty nuclear units in Ontario. The presentation at the conference will bring the audience completely up-to-date on recent events. (author)

  9. Canada-China power experience

    International Nuclear Information System (INIS)

    International energy opportunities were reviewed, with emphasis on China, and on Canada-China Power Inc., alternatively known as 'Team Canada'. Canada-Chine Power Inc., is a company founded by three of Canada's leading engineering consulting firms, i.e., Monenco AGRA Inc., SNC Lavalin Inc., and Acres International Limited. An office was established in Beijing in January 1994. Other Canadian manufacturers and engineering companies also have been actively pursuing hydro power opportunities in China for several years in view of China's enormous demand for power. It was estimated that by the year 2000, China will install 137 GW of new capacity, and foreign investment will account for approximately a third of the growth. AGRA is working on a 5400 MW thermal plant on Hainan Island, and is in final negotiations with the Yangtze Three Gorges Development Corporation for a management information system for their 18200 MW multi-purpose project. Criteria used by AGRA to identify international opportunities include: (1) a large capital spending program in fields with capabilities, expertise and past experience, (2) access to international funding, (3) competitive Canadian technology, and (4) an acceptable business and cultural climate. In assessing the opportunities, AGRA decided to concentrate on providing technologies in greatest need, such as project management systems, computer engineering and CAD systems, and clean coal technology

    2006-01-01

    We monitored populations of Canada thistle biocontrol agents Cassida rubiginosa, Ceutorhynchus litura, Larinus (= Hadroplantus) planus, Urophora cardui, Orellia (= Terellia) ruficauda, and Rhinocyllus conicus on Canada thistle (Cirsium arvense) at two national wildlife refuges in South Dakota from 1999 through 2003. C. litura, U. cardui, O. ruficauda, and R. conicus were present on both refuges. Agent populations were low except for C. litura, which was present in up to 90% of stems in some plots. C. litura infestation did not reduce thistle flowering, stem length, or over-winter survival. There was no change in thistle stem numbers over the study period and no difference in stem numbers in areas of high C. litura populations compared to areas of low C. litura populations. Our results suggest that insect biological control agents are inadequate for reduction of Canada thistle in southern South Dakota.

    Full Text Available ABSTRACT The mainland population of the ruddy-headed goose (Chloephaga rubidiceps breeds in southern Patagonia and winters in the south of Buenos Aires province (Argentina, with a recent estimated size at around 900 individuals. This population is considered "in danger of extinction", while the Malvinas (Falkland Islands population is in well conservation status, with an estimated size of 40,000 birds. The aim of this work is to contribute with updated information about the ruddy-headed goose's population wintering in southern Buenos Aires province. The specific objectives were to better delimit its wintering area, to look for sites with large numbers, to study its habitat used, and to identify main threats to the species. Two intensive surveys were conducted during the austral winter of 1999. The results: (1 confirm the low abundance of the ruddy-headed goose supporting its critical conservation status, (2 corroborate its very restricted distribution, with more than 80 % of sightings concentrated in an area of 13,000 ha in southern Buenos Aires province, and (3 suggest that changes in the species' habitat use during the wintering season appear to be a response to changes in habitat availability, resulting from the growth of crops and pastures. The overlap between the species wintering distribution and the main wheat cropping areas of Argentina results in serious threats to this goose. Management actions are discussed to contribute to the conservation of this endangered species.La población continental del Cauquén colorado (Chloephaga rubidiceps cría en el sur de la Patagonia e inverna en el sur de la provincia de Buenos Aires (Argentina, con un tamaño poblacional estimado recientemente en alrededor de 900 individuos.

    Interferons are a group of antiviral cytokines acting as the first line of defense in the antiviral immunity. Here, we describe the antiviral activity of goose type I interferon (IFNα) and type II interferon (IFNγ) against duck plague virus (DPV). Recombinant goose IFNα and IFNγ proteins of approximately 20 kDa and 18 kDa, respectively, were expressed. Following DPV-enhanced green fluorescent protein (EGFP) infection of duck embryo fibroblast cells (DEFs) with IFNα and IFNγ pre-treatment, the number of viral gene copies decreased more than 100-fold, with viral titers dropping approximately 100-fold. Compared to the control, DPV-EGFP cell positivity was decreased by goose IFNα and IFNγ at 36 hpi (3.89%; 0.79%) and 48 hpi (17.05%; 5.58%). In accordance with interferon-stimulated genes being the "workhorse" of IFN activity, the expression of duck myxovirus resistance (Mx) and oligoadenylate synthetases-like (OASL) was significantly upregulated (p interferon. These findings will contribute to our understanding of the functional significance of the interferon antiviral system in aquatic birds and to the development of interferon-based prophylactic and therapeutic approaches against viral disease.

    While the overall climate for women physicists both in academia and industry has improved significantly over the past decade in Canada, it will be some time before women are well represented. Numbers of women in physics at all academic levels have increased, but are less than ideal at the full professor level. Organizations such as the Canadian Association of University Teachers and local initiatives are striving to minimize the socio-economic and professional gaps between women and men. The Canadian Association of Physicists, through its Committee to Encourage Women in Physics, and the Natural Sciences and Engineering Research Council are supportive and serve as catalysts, bringing together men and women to discuss and address issues concerning women in physics across Canada.

    This report reviews the structure of the electric power industry in Canada, describes the regulatory structures that are in place, and puts the Canadian electricity industry into an international context. It presents statistics on electricity generation and consumption, imports and exports, transmission, costs and pricing, and financing. It forecasts anticipated energy demands, generating capacity and actual generation, exports, fuel requirements, and expenditures. The impacts of demand-side management and non-utility generation are discussed. (82 tabs., 23 figs.)

  7. The nuclear debate in Canada

    International Nuclear Information System (INIS)

    The author argues that the nuclear debate in Canada is concerned less with the safety of nuclear power plants and more with arguments of economics and social decision-making. The nuclear industry cannot afford to neglect the continuing need to inform the public about nuclear risks. But there is also a need to develop specific arguments to increase public acceptance of nuclear energy as an economic, democratic and equitable energy option

    @@ China and Canada released a joint statement to work together to promote the bilateral cooperation in the oil and gas sector in lateJanuary when Canadian Prime Minister Paul Martin paid a state visit to China. Encouraging respective enterprises to expand commercial partnership, the two nations have agreed to take on the energy sector - oil and gas, nuclear energy,energy efficiency and cleaner energy - as "priority areas of long-term mutual cooperation".

  9. Overview of Canada's uranium industry

    International Nuclear Information System (INIS)

    This paper places Canada's uranium industry in its international context. Most uranium, except that produced in the United States, is traded internationally. A brief history of the industry worldwide is given to show how the principal producing areas have fared to date. The industry is young, highly cyclical, and still far from achieving stability. Uranium is a single end-use commodity, entirely dependent on the generation of electricity in nuclear stations, and is without price elasticity: lowering the price does not increase demand. The typical nuclear fuel processing chain has not encouraged or led to much vertical integration. Uranium is subject to more governmental control than any other commodity. The principal market is located in the industrial countries of western Europe, the United States, Canada, and the far east. The uranium supply-demand situation is reviewed, including the current and near-term oversupply and the longer term outlook to 1995. The major negative impact of reactor cancellations and deferments in the United States is discussed. Because of the difficulty in getting reactors on line, it has become easier to forecast the demand for uranium over the next 10 years. It is more difficult to predict how that demand will be met from the more than ample competing sources. Canada's potential for supplying a significant portion of this demand is considered in relation to producers and potential new producers in other countries

  10. Women in Physics in Canada

    2012-10-01

    Here we are in the 21st century in Canada, where most of us would say that young girls and boys have equal access to education, opportunities, and careers of their own choice. In Canada, women currently outnumber men in full-time university enrollment, in Medical Schools and in Law Schools. 48% of the Canadian work force is female, yet women make up only 21% of working professionals in science, engineering and technology. Canada-wide in Physics, the situation is such that only 20% of our BSc graduates are women, and 19% of our PhD graduates are women. It is evident that the ``leaky pipeline'' in Physics leaks most at a young age, before BSc graduation. High school physics statistics in BC indicate that while most of the grade 12 science and math disciplines have roughly equal numbers of young men and women enrolled, this is not the case for high school physics, where province-wide, only 30% of Physics 12 students are women. (Biology is also skewed, but in the other direction: 62% of Biology 12 students are women) This poster will present current statistics and will hopefully be a wake-up call for us all to consider participating in more outreach in science, and especially physics, in our high schools.

  11. Antiviral Biologic Produced in DNA Vaccine/Goose Platform Protects Hamsters Against Hantavirus Pulmonary Syndrome When Administered Post-exposure.

    Nicole Haese

    Full Text Available Andes virus (ANDV and ANDV-like viruses are responsible for most hantavirus pulmonary syndrome (HPS cases in South America. Recent studies in Chile indicate that passive transfer of convalescent human plasma shows promise as a possible treatment for HPS. Unfortunately, availability of convalescent plasma from survivors of this lethal disease is very limited. We are interested in exploring the concept of using DNA vaccine technology to produce antiviral biologics, including polyclonal neutralizing antibodies for use in humans. Geese produce IgY and an alternatively spliced form, IgYΔFc, that can be purified at high concentrations from egg yolks. IgY lacks the properties of mammalian Fc that make antibodies produced in horses, sheep, and rabbits reactogenic in humans. Geese were vaccinated with an ANDV DNA vaccine encoding the virus envelope glycoproteins. All geese developed high-titer neutralizing antibodies after the second vaccination, and maintained high-levels of neutralizing antibodies as measured by a pseudovirion neutralization assay (PsVNA for over 1 year. A booster vaccination resulted in extraordinarily high levels of neutralizing antibodies (i.e., PsVNA80 titers >100,000. Analysis of IgY and IgYΔFc by epitope mapping show these antibodies to be highly reactive to specific amino acid sequences of ANDV envelope glycoproteins. We examined the protective efficacy of the goose-derived antibody in the hamster model of lethal HPS. α-ANDV immune sera, or IgY/IgYΔFc purified from eggs, were passively transferred to hamsters subcutaneously starting 5 days after an IM challenge with ANDV (25 LD50. Both immune sera, and egg-derived purified IgY/IgYΔFc, protected 8 of 8 and 7 of 8 hamsters, respectively. In contrast, all hamsters receiving IgY/IgYΔFc purified from normal geese (n=8, or no-treatment (n=8, developed lethal HPS. These findings demonstrate that the DNA vaccine/goose platform can be used to produce a candidate antiviral

  12. Crisis of Identity in a Multi-cultural Society: The Case of Muslims in Canada

    2000-06-01

    Full Text Available A great majority of studies on ethnic identity or ethnic separatism indicate that a minority group dealing with severe deprivation becomes more frustrated, more aggressive, and more demanding of autonomy or separation. However, in a multi-cultural society where the people can live with their both separate and co-existing identities, the minority group usually demands for greater rights within societies, not an exit from them. This is the case of the Muslims in Canada who constitute a tiny minority in the Canadian population. Since Canada is a multicultural country, the Muslims have not demanded any kind of autonomy but have demanded rights to preserve Islamic values, and their own distinct identity as Muslims. In this article some basic questions are raised regarding the Canadian Muslims. When and how did the Muslims arrive in Canada? What types of challenges they are facing? How do they meet these challenges? What is the future of Muslims in Canada?

    2012-07-18

    In Canada, suicide has transitioned from being a criminal activity with much associated stigma, to being a public health concern that needs to be managed by governments and clinicians in a culturally sensitive manner. In Canada and worldwide, the social attitudes toward and legal interpretation of suicide have been dynamic. Much has been proposed in the development of suicide policy in Canada, however Canada is unique in that it remains one of the only industrialized countries without a national suicide prevention strategy. The current article provides a critical review of the history of suicide in Canada, as well as an appraisal of Canadian suicide prevention policies and key government and political milestones that have impacted suicide policy. Current activity regarding a national suicide prevention strategy in Canada is discussed, as well as potential options for clinician involvement.

    2005-01-01

    Several studies have shown that atmospheric conditions can affect well-being or disease, and that some individuals seem to be more sensitive to weather than others. Since epidemiological data on the prevalence of weather-related health effects are lacking, two representative weather sensitivity (WS) surveys were conducted independently in Germany and Canada. The objectives of this paper are: (1) to identify the prevalence of WS in Germany and Canada, (2) to describe weather-related symptoms and the corresponding weather conditions, and (3) to compare the findings in the two countries. In Germany 1,064 citizens (age >16 years) were interviewed in January 2001, and in Canada 1,506 persons (age >18 years) were interviewed in January 1994. The results showed that 19.2% of the German population thought that weather affected their health “to a strong degree,” 35.3% that weather had “some influence on their health” (sum of both = 54.5% weather sensitive), whereas the remaining 45.5% did not consider that weather had an effect on their health status. In Canada 61% of the respondents considered themselves to be sensitive to the weather. The highest prevalence of WS (high + some influence) in Germans was found in the age group older than 60 years (68%), which was almost identical in the Canadian population (69%). The highest frequencies of weather-related symptoms were reported in Germany for stormy weather (30%) and when it became colder (29%). In Canada mainly cold weather (46%), dampness (21%) and rain (20%) were considered to affect health more than other weather types. The most frequent symptoms reported in Germany were headache/migraine (61%), lethargy (47%), sleep disturbances (46%), fatigue (42%), joint pain (40%), irritation (31%), depression (27%), vertigo (26%), concentration problems (26%) and scar pain (23%). Canadian weather-sensitive persons reported colds (29%), psychological effects (28%) and painful joints, muscles or arthritis (10%). In Germany 32

  15. Splicing of goose parvovirus pre-mRNA influences cytoplasmic translation of the processed mRNA

    Li, Long; Pintel, David J., E-mail: pinteld@missouri.edu

    2012-04-25

    Translation of goose parvovirus (GPV) 72 kDa Rep 1 is initiated from unspliced P9-generated mRNAs in ORF1 from the first in-frame AUG (537 AUG); however, this AUG is bypassed in spliced P9-generated RNA: translation of the 52 kDa Rep 2 protein from spliced RNA is initiated in ORF2 at the next AUG downstream (650 AUG). Usage of the 537 AUG was restored in spliced RNA when the GPV intron was replaced with a chimeric SV40 intron, or following specific mutations of the GPV intron which did not appear in the final spliced mRNA. Additionally, 650 AUG usage was gained in unspliced RNA when the GPV intron splice sites were debilitated. Splicing-dependent regulation of translation initiation was mediated in cis by GPV RNA surrounding the target AUGs. Thus, nuclear RNA processing of GPV P9-generated pre-mRNAs has a complex, but significant, effect on alternative translation initiation of the GPV Rep proteins.

    Mapel, William J.; Hail, William J.

    1954-01-01

    Thirteen core holes, totaling 2,023 feet, were drilled during the fall of 1953 to explore the grade and extent of uranium-bearing beds of carbonaceous shale and lignite in the east-central part of the Goose Creek district, Cassia County, Idaho. The beds tested are interbedded with volcanic ash, bentonite, greenish-gray shale, sandstone, and conglomerate in two fairly well defined zones in the lower part of the Salt Lake formation of lower Pliocene age. Nine holes penetrated carbonaceous shale beds in the Barrett zone, and one hole penetrated carbonaceous shale and lignite beds in zone B, 160 feet stratigraphically below the Barrett zone. The highest concentration of uranium found by drilling is 0.10 percent in the upper part of a 4-foot bed of carbonaceous shale and lignite in zone B. The grade of carbonaceous shale beds in the Barrett zone ranges from 0.044 percent to less than 0.003 percent uranium. Inferred reserves in the district are estimated to be 790,000 tons in beds 1 foot or more thick containing an average of 0.014 percent or 120 tons of uranium.

These first pages provide an overview of Canada's fusion work and its underlying basis of science and technology

  19. Landfill gas management in Canada

    International Nuclear Information System (INIS)

    Landfill gas produced from solid waste landfills is one of the most significant sources of anthropogenic methane in Canada. Methane, a potent greenhouse gas, is 24.5 times more powerful than carbon dioxide by weight in terms of global climate change. Landfill gas recovery plays an important role in Canada's commitment to stabilize greenhouse gas emissions at 1990 levels by the year 2000 under the United Nations Framework Convention on Climate Change. Landfill gas is a potentially harmful emission that can be converted into a reliable environmentally-sustainable energy source used to generate electricity, fuel industries and heat buildings. The recovery and utilization of landfill gas is a win-win situation which makes good sense from local, regional and global perspectives. It provides the benefits of (1) reducing the release of greenhouse gases that contribute to global warming; (2) limiting odors; (3) controlling damage to vegetation; (4) reducing risks from explosions, fires and asphyxiation; (5) converting a harmful emission into a reliable energy source; and (6) creating a potential source of revenue and profit. Canadian landfills generate about 1 million tons of methane every year; the equivalent energy of 9 million barrels of oil (eight oil super tankers), or enough energy to meet the annual heating needs of more than half a million Canadian homes. Currently, twenty-seven facilities recover and combust roughly 25% of the methane generated by Canadian landfills producing about 3.2 PJ (1015 Joules) of energy including 80 MW of electricity and direct fuel for nearby facilities (e.g., cement plants, gypsum board manufacturers, recycling facilities, greenhouses). This paper reviews landfill gas characteristics; environmental, health and safety impacts; landfill gas management in Canada; the costs of landfill gas recovery and utilization systems; and on-going projects on landfill gas utilization and flaring

    Specialization is a pervasive movement in medicine. How specialties develop is a complex phenomenon and does not depend solely on the growth of knowledge. The history of geriatrics in Canada is presented as an example of specialization in our country. The gestation period extended over decades. Practitioners moved from partial specialization to a full-time practice in the care of older patients. Opposition to the emerging specialty was mounted by established fields of practice. The choices made by the leaders of Canadian geriatrics molded the evolution of the specialty and have contributed to its precarious status at the present time.

    Global warming increasingly is becoming a concern for society. Most reported warming trends are based on measured increases in air temperatures. However, trends in soil temperatures, also an important indicator of climate change, are less often reported. Qian et al. analyzed soil temperature data from 30 climate stations across Canada covering the period from 1958 to 2008; the data cover soil temperatures at several depths up to 150 centimeters. They also analyzed air temperature, precipitation, and snow cover depth at the same locations. (Journal of Geophysical Research­Atmospheres, doi:10.1029/2010JD015012, 2011)

  4. Energy in Canada: An overview

    International Nuclear Information System (INIS)

    Recent changes in the North American natural gas industry are discussed, with a focus on how these changes will affect the ability of Alberta and Canadian natural gas supply to meet market growth. These changes include a decline in the merchant role of many of the major interstate pipelines, resulting in a larger number of smaller-sized purchasers for natural gas marketers to deal with; a greater extent of direct purchasing by local distribution companies and large industrial users, combined with a preference for spot sales rather than long-term commitments; direct marketing of uncontracted gas by many producers and brokers; a bidding type of sales process rather than a negotiated process; and price deregulation. It is foreseen that long term security of supply will again become an important factor to North American buyers, and Canada can offer substantial supplies under secure long term contracts. Marketers will have to seek new market targets such as cogeneration plants and the transportation sector. Access to pipeline transport will be one of the major factors in obtaining new markets. The Canada-USA free trade agreement is viewed as a positive development which should help Canadian gas marketers to gain and retain U.S. customers

  5. Nuclear emergency preparedness in Canada

    International Nuclear Information System (INIS)

    The preparedness of utilities and government agencies at various levels for dealing with nuclear emergencies occurring at nuclear reactors in Canada is reviewed and assessed. The review is centered on power reactors, but selected research reactors are included also. Emergency planning in the U.S.A., Germany and France, and international recommendations on emergency planning are reviewed to provide background and a basis for comparison. The findings are that Canadians are generally well protected by existing nuclear emergency plans at the electric utility and provincial levels but there are improvements that can be made, mainly at the federal level and in federal-provincial coordination. Ten issues of importance are identified: commitment to nuclear emergency planning by the federal government; division of federal and provincial roles and responsibilities; auditing of nuclear emergency preparedness of all levels of government and of electric utilities; the availability of technical guidance appropriate to Canada; protective action levels for public health and safety; communication with the public; planning and response for the later phases of a nuclear emergency; off-site exercises and training; coordination of international assistance; and emergency planning for research reactors.

    2014-12-01

    Canada is home to a growing immigrant population. However, immigrant mental health declines over time following arrival in Canada. Canada's Mental Health Strategy emphasizes the importance of research that gathers information from multiple sources of knowledge to identify the mental health challenges faced by diverse immigrant populations. Mixed methods research (MMR) is well suited for this task. However, a dearth of research exists on the application of MMR to the study of immigrant mental health. A systematic review of the published MMR literature in Canadian immigrant mental health was carried out. Overall, existing MMR studies failed to incorporate correct mixed methods terminology and fully integrate the quantitative and qualitative components of the research. A checklist of important elements to include in MMR studies is offered.

  12. Growth Of Broadband And ICT Adoption By SMEs In Atlantic Canada

    2012-06-01

    Full Text Available Since 2005, we have conducted three Atlantic Canada-wide surveys of SME businesses benchmarking levels of ICT adoption, change in adoption, as well as the role of marketing and export on ICT usage in helping to create growing and sustainable business opportunities. Despite Atlantic Canada’s low population base and distance to major population centres, SMEs in the region show strong levels of adoption of various ICT products and services. Broadband access, website adoption and online purchasing is now over 90%. Even newer socialnetworking services, such as web analytics, search engine optimization, and the use of Twitter are being adopted by as many of 44% of the SMEs. These adoption rates will be compared with our previous studies to document the historical growth within Atlantic Canada, as well as compare these baseline measures to other regions within Canada, as well as studies of comparable regions worldwide.

  13. Accidents in Canada: mortality and hospitalization.

    Science.gov (United States)

    Riley, R; Paddon, P

    1989-01-01

    For Canadians under 45, accidents are the leading cause of both death and hospitalization. For the Canadian population as a whole, accidents rank fourth as a cause of death, after cardiovascular disease (CVD), cancer and respiratory disease. This article analyzes accident mortality and hospitalization in Canada using age-specific rates, age-standardized mortality rates (ASMR), and potential years of life lost (PYLL). The six major causes of accidental death for men are motor vehicle traffic accidents (MVTA), falls, drowning, fires, suffocation and poisoning. For women, the order is slightly different: MVTA, falls, fires, suffocation, poisoning and drowning. From 1971 to 1986, age-standardized mortality rates (ASMR) for accidents decreased by 44% for men and 39% for women. The largest decrease occurred in the under 15 age group. Accidents accounted for 11.5% of total hospital days in 1985, and 8% of hospital discharges. Because young people have the highest rates of accidental death, potential years of life lost (PYLL) are almost as high for accidents as for cardiovascular disease, although CVD deaths outnumbered accidental deaths by almost five to one in 1985.

    To provide an overview of the current status of percutaneous vertebroplasty (PVP) practice in Canada, including the preprocedure work up operative technique and follow-up practice of physicians performing the procedure in this county. Questionnaires were emailed to 31 institutions performing percutaneous vertebroplasty across Canada. Twenty-three (74.2%) completed surveys were returned, representing data from 1,516 vertebroplasties performed by 66 radiologists and surgeons. Preoperative routine imaging and screening practice varies widely. The majority of respondents perform PVP under conscious sedation; however, an anaesthetist is present in only 22% of institutions. Biplane fluoroscopy is used in 43.5% of practices. The preference for unipedicular or bipedicular injection varies: in 7 institutions, a unipedicular approach is used in at least 80% of cases. Patients receive a follow-up by the screening physician in 65.2% of institutions. There were 4 complications requiring treatment. Venous and intradiscal extravasation rates were 20.8% and 25.3%, respectively; however, the vast majority of these were clinically insignificant. PVP complication rates reported in our Canadian survey compare favourably with those in the published literature. The number of PVPs performed annually in the institutions surveyed appears small, relative to the figures from the United States. The prevalence of osteoporosis and incidence of vertebral compression fractures in Canada is increasing as the population ages, and demand for PVP is likely to rise significantly in the coming years.

    2008-06-01

    Full Text Available Abstract Background Research into health and health-care seeking behaviour amongst immigrant populations suggests that culturally-based behaviours change over time towards those prevalent in the host culture. Such acculturation of immigrant groups occurs as part of the interaction of immigrants with mainstream culture. This study examined the acculturation of Ghanaian immigrants in Greater Toronto Area (Canada focusing particularly on attitudes towards and usage of Ghanaian traditional medicine (TRM. Methods The study used both quantitative and qualitative methods. Structured questionnaire interviews were conducted with a sample of Ghanaians in active collaboration with the Ghanaian-Canadian Association in the Greater Toronto Area (GTA. A total of 512 questionnaire interviews were conducted. In addition, three focus groups of nine participants each were conducted with a sub-sample of Ghanaians in Canada. Results Both the questionnaire and the focus groups indicated that nearly 73% of the Ghanaian immigrants in Canada have a positive attitude toward Ghanaian TRM. This is in comparison with less than 30% who have changed their attitude for various reasons. Some of the attraction of TRM lies in its holistic origin. Ghanaians in the GTA have been pursuing 'integration' and 'assimilation' in their acculturation in Canada. Some have given up or modified some of their attitudes and opinions toward TRM to embrace the 'modern' or 'civilized' way of living. Conclusion There is the need for health care providers and other stakeholders to be aware of the influence of religion on African immigrants during their acculturation process. Although modernity is said to be founded on the 'ruthless undermining of tradition', there is no evidence to suggest that Ghanaian traditional religion has been undermined to such an extent that there is a major change in attitudes towards TRM.

  17. Trends in extinction risk for imperiled species in Canada.

    Directory of Open Access Journals (Sweden)

    Brett Favaro

    Full Text Available Protecting and promoting recovery of species at risk of extinction is a critical component of biodiversity conservation. In Canada, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC determines whether species are at risk of extinction or extirpation, and has conducted these assessments since 1977. We examined trends in COSEWIC assessments to identify whether at-risk species that have been assessed more than once tended to improve, remain constant, or deteriorate in status, as a way of assessing the effectiveness of biodiversity conservation in Canada. Of 369 species that met our criteria for examination, 115 deteriorated, 202 remained unchanged, and 52 improved in status. Only 20 species (5.4% improved to the point where they were 'not at risk', and five of those were due to increased sampling efforts rather than an increase in population size. Species outcomes were also dependent on the severity of their initial assessment; for example, 47% of species that were initially listed as special concern deteriorated between assessments. After receiving an at-risk assessment by COSEWIC, a species is considered for listing under the federal Species at Risk Act (SARA, which is the primary national tool that mandates protection for at-risk species. We examined whether SARA-listing was associated with improved COSEWIC assessment outcomes relative to unlisted species. Of 305 species that had multiple assessments and were SARA-listed, 221 were listed at a level that required identification and protection of critical habitat; however, critical habitat was fully identified for only 56 of these species. We suggest that the Canadian government should formally identify and protect critical habitat, as is required by existing legislation. In addition, our finding that at-risk species in Canada rarely recover leads us to recommend that every effort be made to actively prevent species from becoming at-risk in the first place.

  18. Telomere dynamics in a long-lived bird, the barnacle goose

    Full Text Available Abstract Background Theories of ageing predict a trade-off between metabolism, reproduction, and maintenance. Species with low investment in early reproduction are thus expected to be able to evolve more efficient maintenance and repair mechanisms, allowing for a longer potential life span (intrinsic longevity. The erosion of telomeres, the protective caps at the ends of linear chromosomes, plays an important role in cellular and organismal senescence, signalling the onset of age-related disease due to accumulation of unrepaired somatic damage. Using extensive longitudinal data from a long-term study of a natural population of barnacle geese Branta leucopsis, we investigated individual rates of telomere length changes over two years in 34 birds between 0 and 22 years of age, covering almost 80% of the species’ lifespan. Results We show that telomeres in this long-lived bird are very well maintained, as theoretically expected, with an average loss rate of only 5 base pairs per year among adults. We thus found no significant relationship between change in telomere length and age. However, telomeres tended to shorten at a faster pace in juveniles compared to adults. For the first time, we demonstrate a faster telomere attrition rate in females compared to males. We found no correlation between telomere loss rate and adult survival or change in body mass. Conclusions Our results add further support for a link between longevity and telomere maintenance, and highlight the complexities of telomere dynamics in natural populations.

  19. Oil price uncertainty in Canada

    Bernanke [Bernanke, Ben S. Irreversibility, uncertainty, and cyclical investment. Quarterly Journal of Economics 98 (1983), 85-106.] shows how uncertainty about energy prices may induce optimizing firms to postpone investment decisions, thereby leading to a decline in aggregate output. Elder and Serletis [Elder, John and Serletis, Apostolos. Oil price uncertainty.] find empirical evidence that uncertainty about oil prices has tended to depress investment in the United States. In this paper we assess the robustness of these results by investigating the effects of oil price uncertainty in Canada. Our results are remarkably similar to existing results for the United States, providing additional evidence that uncertainty about oil prices may provide another explanation for why the sharp oil price declines of 1985 failed to produce rapid output growth. Impulse-response analysis suggests that uncertainty about oil prices may tend to reinforce the negative response of output to positive oil shocks. (author)

    Petro-Canada is a dominant player in the petroleum industry in Western Canada as well as on the Grand Banks offshore Newfoundland. This report presents a review of operations, provides detailed statements of the corporation's finances, and a wealth of information of interest to shareholders. The report states that in 1997 Petro-Canada achieved record financial results, following a dramatic turnaround over the past five years. Net earnings for 1997 were $306 million, a $59 million increase over 1996. The company's share price appreciated 34 per cent in 1997 and was one of the most heavily traded stocks in Canada. The company plans to maximize shareholder value by reducing its interests in conventional oil from mature fields in western Canada and by re-investing the proceeds in natural gas development. Petro-Canada is also committed to an expansion that will double production at the Syncrude oil sands plant over the next decade and has tested large in-situ oil sands resources for potential development in northeastern Alberta. On the Atlantic coast too, Petro-Canada is delivering leadership with increasing production from Hibernia, and final approvals in place to proceed with development of the Terra Nova field. International operations are also contributing to the Corporation's profitability by delivering new production from oil fields offshore Norway and from the Sahara Desert in North Africa. tabs., figs

    Mothers against decapentaplegic homolog 4 (SMAD4) is an important protein in animal reproduction. It plays pivotal roles in cellular pathways, including apoptosis. The expression profile of the SMAD4 gene in goose ovarian follicles has not been reported. In this study, the SMAD4 coding sequence was cloned from the Yangzhou goose. A phylogenetic analysis was performed and mRNA expression was examined in various tissues using quantitative real-time PCR. An alternative splice form of SMAD4, SMAD4-b having 1656 bp, was identified. SMAD4-a mRNA was widely expressed in various healthy tissues, whereas SMAD4-b was very weakly expressed. SMAD4 mRNA in the ovary and oviduct was significantly higher than that in the pituitary and hypothalamus. SMAD4 mRNA expression analysis in hierarchical follicles showed that the level of SMAD4 mRNA was higher in large white follicles and post-ovulatory follicles than in the other follicles. The results indicate that SMAD4 might be involved in the recruitment of hierarchical follicles. PMID:27108648

It consists of in-depth interviews of Latin American women from diverse countries who obtained temporary work visas as exotic dancers. The objective of the study is to determine the ways in which women are recruited in their countries of origin, transported to Canada and what happens to them upon arrival. The author proposes that the conditions inherent to migration, more than women's legal status, determines their emotional, economic and legal well-being. However, upon obtaining legal residency in Canada, abuse committed by employers and state agents is significantly reduced.

    A recent Canada goose (Branta canadensis) die-off at a petroleum refinery fly ash pond in Delaware was attributed to vanadium (V) toxicity. Because of the paucity of V toxicity data for wild birds, a series of studies was undertaken using the forms of V believed to have resulted in this incident. In 7-d single oral dose trials with mallard drakes (Anas platyrhynchos), the estimated median lethal dose (LD50) for vanadium pentoxide was 113 mg/kg body weight, while the LD50 for sodium metavanadate was 75.5 mg/kg. Sodium metavanadate was found to be even more potent (LD50 = 37.2 mg/kg) in male Canada geese. The most distinctive histopathological lesion of both forms of V was Iympho-granulocytic enteritis with hemorrhage into the intestinal lumen. Vanadium accumulation in liver and kidney was proportional to the administered dose, and predictive analyses based on these data suggest that V concentrations of 10 :g/g dry weight (dw) in liver and 25 ug/g dw in kidney are associated with mortality (>90% confidence that exposure is >LD50) in mallards acutely exposed to sodium metavanadate. Chronic exposure to increasing dietary concentrations of sodium metavanadate (38.5 to 2651 ppm) over 67 d resulted in V accumulation in liver and kidney (25.2 and 13.6 ug/g dw, respectively), mild intestinal hemorrhage, blood chemistry changes, and evidence of hepatic oxidative stress in mallards, although some of these responses may have been confounded by food avoidance and weight loss. Dietary exposure of mallards to 250 ppm sodium metavanadate for 4 wk resulted in modest accumulation of V in liver and kidney <5 ug/g dw) and mild intestinal hemorrhage. Based on these data and other observations, it is unlikely that chronic low-level dietary exposure to V poses a direct lethal hazard to wildlife. However, point sources, such as the V-laden fly ash pond encountered by geese at the petroleum refinery in Delaware, may pose a significant hazard to water birds.

    We confirm a 0.995 d periodic planetary transit-like signal, KOI 6705.01, in the Kepler lightcurve of the star KIC 6423922. Optical and infrared spectra show that this star is a mid M-type dwarf with an effective temperature $= 3327 \\pm 60$K, metallicity [Fe/H] $= -0.08 \\pm 0.10$, radius $= 0.31 \\pm 0.03 R_{\\odot}$, and mass $= 0.28 \\pm 0.05 M_{\\odot}$. The star is $\\approx 70$ pc away and its space motion, rotation period, and lack of H$\\alpha$ emission indicate it is an older member of the "thin disk" population. On the other hand, the star exhibits excess infrared emission suggesting a dust disk more typical of a very young star. If the KOI 6705.01 signal is produced by a planet, the transit depth of 60 ppm means its radius is only $0.26^{+0.034}_{-0.029} R_{\\oplus}$, or about the size of the Moon. However, the duration ($\\gtrsim 3$~hr) and time variation of KOI 6705.01 are anomalous: the signal was undetected in the first two years of the mission and increased through the latter two years.

  1. Canada's constitutional separation of (wind) power

    International Nuclear Information System (INIS)

    This paper investigates the impact that a federal government structure has on strategic selection of renewable energy policy instruments. The context for this study centers on wind power development in Canada. Canada is a nation that is blessed by all the attributes necessary to catalyze global leadership in installed wind power capacity. Unfortunately, the constitutional separation of powers that underpins Canada's federal system impedes the creation of a national wind power development strategy because Canada's provinces have constitutional authority over electricity governance. The insights gleaned from the case study are used to develop a conceptual framework for understanding the impact that federal structure has on policy instrument selection and efficacy under areas of federal, regional and concurrent policy jurisdiction. Finally, this framework is re-applied to identify specific approaches the Canadian federal government could take to resolve what currently amounts to be a fragmented, ineffective approach to wind power development planning.

  4. Wheat Production and Wheat Rust Management in Canada

    Wheat is Canada's the largest crop with most of the production in the western Canadian Prairie Provinces of Manitoba, Saskatchewan and Alberta. There were approximately 10 million (M) hectares (hm2) seeded to wheat in Canada, including 7 M hm2 of hexaploid spring wheat (Triticum aestivum L.), 2 M hm2 of durum wheat (T. turgidum L. ssp. durum (Desf.) Husn.), and 1 M hm2 of winter wheat (T. aestivum). Within hexaploid wheat there has been diversification into a number of market classes based on different end-use quality criteria. The predominant spring bread wheat class has been the Canada Western Red Spring (CWRS) class. Historically, the disease of major concern in wheat was stem rust, caused by Puccinia graminis f. sp. tritici. The first significant stem rust resistant cultivar in Canada was Thatcher, grown extensively from 1939 until the early 1970s. Thatcher, however, was very susceptible to leaf rust, caused by Puccinia triticina. Over years, improved resistance to both stem and leaf rust was achieved with the release of cultivars with additional genes for resistance, primarily Sr2, Sr6, Sr7a, Sr9b, Lr13, Lr14a, Lr16, and Lr34. The genetic resistance has adequately controlled stem rust but leaf rust continues to cause significant loss, partially due to changes in the P. triticina population which reduced the effectiveness of resistance genes such as Lr13 and Lr16. Stripe rust on wheat, caused by Puccinia striiformis f. sp. tritici, was historically a problem under irrigation in southern Alberta, but since 2000, it has been found annually in the central Canadian prairies and southern Ontario. The genetic basis of resistance to stripe rust in most Canadian wheat cultivars has not been determined, although Yr18 provides partial resistance in many cultivars. In the future, other rust diseases, such as wheat stripe rust, or highly virulent new pathotypes of current rust pathogens, such as P. graminis f. sp. tritici race Ug-99, may pose

  9. Canada - committed to a nuclear future

    International Nuclear Information System (INIS)

    There has been a flurry of activity in the Ontario electricity sector over the last 2 years as the government continued to work at averting a major crisis of supply in Canada's most populous province.As stated by the Ministry of Energy in 2004, Ontario needs to refurbish, rebuild, replace or conserve 25,000 megawatts of generating capacity by the year 2020 to meet growing demand while replacing its polluting coal-fired generating plants. That represents 80 per cent of Ontario's current generating capacity and would require an investment of $25 to $40 billion. Action has been taken. The government has completed a restructuring of the electricity market with new legislation and has undertaken a number of major procurement initiatives to enable the system to operate until about 2015. These include contracts for significant wind generation and other renewables supply, new gas generation, conservation and demand management and the refurbishment of idled nuclear units. The Ontario Power Authority as now issued it ''Supply Mix Advice'' to address the needs of the province for the long term (20 years). The recommendations would ''increase the share of renewable sources' in Ontario's supply mix, maintain the share of nuclear generation, and replace coal by increasing the share of gas-fired generation and renewable resources.'' It clearly recognizes the importance of nuclear power as a clean and economic option to meet the ongoing base load requirements and states that the nuclear share can be achieved through refurbishing existing units, rebuilding on existing sites and undertaking ''new build'' plants. This paper will examine government's plan to maintain the share of nuclear power at about 50% of electricity generated, and address the important issues required to make decisions on future refurbishments and new build

  10. Increasing turbine vendor competition in Canada

    Energy Technology Data Exchange (ETDEWEB)

    Magee, J.T. [Emerging Energy Research, Cambridge, MA (United States)

    2008-07-01

    An overview of the wind turbine market in Canada was presented. Canada is now experiencing increased turbine vendor competition. Trends in wind turbine OEM market shares in Canada have increased from 10 per cent in 2000 to over 70 per cent in 2007. Several major companies in Canada have signed large-scale orders for delivery in 2010. It is expected that future wind turbine demands in all areas of Canada will increase. However, projections for Canadian wind growth demonstrate the difficulties provinces are now facing in trying to attract manufacturing investment away from the United States. Growth in wind turbine investment is in the process of creating a more robust North American wind turbine generator chain. However, the majority of new facilities are located in the United States. It is not known if Quebec's wind turbine generators will be viable outside of fulfilling Hydro-Quebec's tendering process. Canada's wind industry must consider equipment transport costs as well as a shortage of operating and maintenance service infrastructure. It was concluded that growth in the United States is expected to have a positive impact on Canadian wind energy customers. tabs., figs.

    Full Text Available A population of belugas (Delphinapterus leucas inhabiting the estuary of the St Lawrence river in Quebec, Canada, was depleted by unregulated hunting, not closed until 1979. Surveys in 1977 showed only a few hundred in the population. Surveys since then have produced increasing estimates of population indices. An estimate of the population, fully corrected for diving animals, was 1,238 (SE 119 in September 1997. The population was estimated to have increased from 1988 through 1997 by 31.4 belugas/yr (SE 13.1. Observations of population age structure, as well as data on age at death obtained from beach-cast carcasses, do not indicate serious problems at the population level, although there are indications that mortality of the oldest animals may be elevated. Few animals appear to live much over 30 years. From examination of beach-cast carcasses, it appears that most deaths are due to old age and disease; hunting is illegal, ship strikes and entrapments in fishing gear are rare, ice entrapments and predation are unknown. Among beach-cast carcasses recovered and necropsied, about 23% of the adults have malignant cancers, while most of the juveniles have pneumonia; other pathological conditions are diverse. No factors are known to be limiting numbers of this population. Habitat quality factors, including persistent contaminants, boat traffic and harassment, may affect the population’s rate of increase, but these effects have not been quantitatively evaluated. Comprehensive legislation exists with powers to protect the population and the environment of which it is a component, but application and enforcement of the laws is not without problems.

  12. The Geographic Distribution of Liver Cancer in Canada Does Not Associate with Cyanobacterial Toxin Exposure

    2015-11-01

    Full Text Available Background: The incidence of liver cancer has been increasing in Canada over the past decade, as has cyanobacterial contamination of Canadian freshwater lakes and drinking water sources. Cyanotoxins released by cyanobacteria have been implicated in the pathogenesis of liver cancer. Objective: To determine whether a geographic association exists between liver cancer and surrogate markers of cyanobacterial contamination of freshwater lakes in Canada. Methods: A negative binomial regression model was employed based on previously identified risk factors for liver cancer. Results: No association existed between the geographic distribution of liver cancer and surrogate markers of cyanobacterial contamination. As predicted, significant associations existed in areas with a high prevalence of hepatitis B virus infection, large immigrant populations and urban residences. Discussion and Conclusions: The results of this study suggest that cyanobacterial contamination of freshwater lakes does not play an important role in the increasing incidence of liver cancer in Canada.

  13. Extratropical Transitions in Atlantic Canada: Impacts and Adaptive Responses

    . Storm surge damage occurred along the north shore of the Bonavista Peninsula. Similar effects, differing only in the size of the affected areas, have resulted from several extratropical transitions which have impacted Atlantic Canada since July 1989. Extratropical transition "Leslie" impacted Newfoundland on 10-11 September 2012. Although the area affected was comparable to "Igor", wind velocities and rainfall totals were less, fortunately limiting damage. Preparation, advance warning to the population, proaction, and response efforts all showed significant improvement, however, indicating that the experience gained from coping with "Igor" had been successfully applied in adaptation to "Leslie". Extratropical transitions pose a significantly different set of challenges for adaptation in comparison to purely tropical hurricanes, and responses and adaptation strategies should be tailored to address these specific events. Calculating the frequency, magnitude and intensity of potential shifts is important for accurate forecasting and public awareness, safety management, preparedness, and adaptation. Available data indicate an increase in extratropical frequency and severity in Atlantic Canada since 1991, but there are difficulties in establishing the extent and nature of transition for previous storm events. A cautionary policy would assume no significant changes in extratropical transition frequency for Atlantic Canada, but would also acknowledge that large events remain probable.

    Full Text Available Canada has coastlines on three of the four oceans on the globe, namely, the Pacific, Atlantic and Arctic oceans. The Pacific and Atlantic oceans are connected to the Arctic Ocean in the north, but still they are three distinct oceans, and need three individual tsunami warning systems. Tsunamis in the Arctic Ocean are not as well documented as in the Pacific and Atlantic oceans. From what is known, tsunamis in the Arctic Ocean are rare and probably are small in amplitude. Because of very low population density, around the Canadian Arctic, at present, there is no priority for a tsunami warning system for Arctic Canada. For the Pacific Ocean, a tsunami warning system is in existence since 1948. In at least one sense, the warning aspects of the tsunami warning system for the Pacific coast of Canada, is relatively simple and straight forward, because it involves only the federal government (PSEPC and the provincial government of British Columbia (PEP. For the Atlantic Ocean, A tsunami warning system is now being established. The warning aspects will be some what more complex for eastern Canada, since it not only involves the federal government, but also five provinces, namely, Newfoundland and Labrador, Nova Scotia, New Brunswick, Prince Edward Island and Quebec. The Alaska tsunami warning center (ATWC in Palmer, Alaska, provides tsunami warnings for both Pacific and Atlantic Canada.

    Michael J Garner

    Full Text Available Antimicrobial resistance (AMR of infectious agents is a growing concern for public health organizations. Given the complexity of this issue and how widespread the problem has become, resources are often insufficient to address all concerns, thus prioritization of AMR pathogens is essential for the optimal allocation of risk management attention. Since the epidemiology of AMR pathogens differs between countries, country-specific assessments are important for the determination of national priorities.To develop a systematic and transparent approach to AMR risk prioritization in Canada.Relevant AMR pathogens in Canada were selected through a transparent multi-step consensus process (n=32. Each pathogen was assessed using ten criteria: incidence, mortality, case-fatality, communicability, treatability, clinical impact, public/political attention, ten-year projection of incidence, economic impact, and preventability. For each pathogen, each criterion was assigned a numerical score of 0, 1, or 2, and multiplied by criteria-specific weighting determined through researcher consensus of importance. The scores for each AMR pathogen were summed and ranked by total score, where a higher score indicated greater importance. A sensitivity analysis was conducted to determine the effects of changing the criteria-specific weights.The AMR pathogen with the highest total weighted score was extended spectrum B-lactamase-producing (ESBL Enterobacteriaceae (score=77. When grouped by percentile, ESBL Enterobacteriaceae, Clostridium difficile, carbapenem-resistant Enterobacteriaceae, and methicillin-resistant Staphylococcus aureus were in the 80-100th percentile.This assessment provides useful information for prioritising public health strategies regarding AMR resistance at the national level in Canada. As the AMR environment and challenges change over time and space, this systematic and transparent approach can be adapted for use by other stakeholders domestically and

    Full Text Available Background . Canada's North is a diverse, sparsely populated land, where inequalities and public health issues are evident, particularly for Aboriginal people. The Northern public health workforce is a unique mix of professional and paraprofessional workers. Few have formal public health education. From 2009 to 2012, the Public Health Agency of Canada (PHAC collaborated with a Northern Advisory Group to develop and implement a strategy to strengthen public health capacity in Canada's 3 northern territories. Access to relevant, effective continuing education was identified as a key issue. Challenges include diverse educational and cultural backgrounds of public health workers, geographical isolation and variable technological infrastructure across the north. Methods . PHAC's Skills Online program offers Internet-based continuing education modules for public health professionals. In partnership with the Northern Advisory Group, PHAC conducted 3 pilots between 2008 and 2012 to assess the appropriateness of the Skills Online program for Northern/Aboriginal public health workers. Module content and delivery modalities were adapted for the pilots. Adaptations included adding Inuit and Northern public health examples and using video and teleconference discussions to augment the online self-study component. Results . Findings from the pilots were informative and similar to those from previous Skills Online pilots with learners in developing countries. Online learning is effective in bridging the geographical barriers in remote locations. Incorporating content on Northern and Aboriginal health issues facilitates engagement in learning. Employer support facilitates the recruitment and retention of learners in an online program. Facilitator assets included experience as a public health professional from the north, and flexibility to use modified approaches to support and measure knowledge acquisition and application, especially for First Nations, Inuit and

    which failed to do so and could only maintain positive energy budgets by grazing high-quality Alopecurus, Cynodon and Eleocharis. However, all three species failed to maintain positive energy balance and lost mass in midwinter. These results have important implications for explaining the divergent...... partitioning in the distribution of closely related species. By estimating daily energy expenditure (based on observed activity budgets) and energy intake (using the indigestible marker method in food and faeces), we compared the field energy budgets of three wintering herbivorous goose species differing...... in body size feeding on the same Carex meadows. Throughout the winter, the larger Bean Geese Anser fabalis serrirostris and Greater White-fronted Geese Anser albifrons maintained positive energy budgets grazing lower quality Carex, in contrast to the smaller Lesser White-fronted Geese Anser erythropus...

    Full Text Available Highly pathogenic avian influenza H5N1 (HPAI H5N1 viruses can infect mammals, including humans, causing severe systemic disease with the inhibition of the immune system and a high mortality rate. In conditions of lymphoid tissue depletion, the liver plays an important role in host defence against viruses. The changes in mice liver infected with HPAI H5N1 virus A/goose/Krasnoozerskoye/627/05 have been studied. It has been shown that the virus persistence in the liver leads to the expression of proinflammatory cytokines (TNF-α, IL-6 and intracellular proteases (lysozyme, cathepsin D, and myeloperoxidase by Kupffer cells. Defective antiviral response exacerbates destructive processes in the liver accelerating the development of liver failure.

  20. Opportunities in Canada's growing wind energy industry

    International Nuclear Information System (INIS)

    Investment in Canada's wind sector is projected to reach $8 billion by 2012, and growth of the sector is expected to create over 16,000 jobs. Canada's wind energy capacity grew by 54 per cent in 2005 alone, aided in part by supportive national policies and programs such as the Wind Power Production Incentive (WPPI); the Canadian Renewable Conservation Expense (CRCE) and Class 43.1 Capital Cost Allowance; and support for research and development. Major long-term commitments for clean power purchases, standard offer contracts and renewable portfolio standards in several provinces are encouraging further development of the wind energy sector. This paper argued that the development of a robust Canadian wind turbine manufacturing industry will enhance economic development, create opportunities for export; and mitigate the effects of international wind turbine supply shortages. However, it is not known whether Canadian wind turbine firms are positioned to capitalize on the sector's recent growth. While Canada imports nearly all its large wind turbine generators and components, the country has technology and manufacturing strengths in advanced power electronics and small wind systems, as well as in wind resource mapping. Wind-diesel and wind-hydrogen systems are being developed in Canada, and many of the hybrid systems will offer significant opportunities for remote communities and off-grid applications. Company partnerships for technology transfer, licensing and joint ventures will accelerate Canada's progress. A recent survey conducted by Industry Canada and the Canadian Wind Energy Association (CanWEA) indicated that the total impact of wind energy related expenditures on economic output is nearly $1.38 billion for the entire sector. Annual payroll for jobs in Canada was estimated at $50 million, and substantial employment growth in the next 5 years is expected. Canada offers a strong industrial supply base capable of manufacturing wind turbine generators and

    There is relatively little known about the demand for allograft tissues in Canada. The Canadian Council for Donation and Transplantation (CCDT) is a national advisory body that undertook a comprehensive "market survey" to estimate surgical demand for human allograft tissues in Canada. The report "Demand for Human Allograft Tissue in Canada" reflects survey results sent to 5 prominent User Groups. User Groups were identified as orthopaedic surgeons; neurosurgeons; corneal transplant surgeons; plastic surgeons, specifically those at Canadian Burn Units; and cardiac surgeons (adult and paediatric surgery). The demand for allograft grafts was determined and then extrapolated across the total User Group and then increases in allograft tissue use over the next 1-2 years across User Groups were predicted. The overall response rate for the survey was 21.4%. It varied from a low of 19.6% for the orthopaedic survey to a high of 40.5% for the corneal survey. The estimated current demand for allograft tissue in Canada ranges from a low of 34,442 grafts per year to a high of 62,098 grafts per year. The predicted increase in use of allograft tissue over the next 1-2 year period would suggest that annual demand could rise to somewhere in the range of 42,589-72,210 grafts. The highest rated preferences (98% and 94%) were for accredited and Canadian tissue banks, respectively. This study represents a key step in addressing the paucity of information concerning the demand for allograft tissue in Canada.

  2. Latitudinal-Related Variation in Wintering Population Trends of Greylag Geese (Anser Anser along the Atlantic Flyway: A Response to Climate Change?

    Directory of Open Access Journals (Sweden)

    Cristina Ramo

    Full Text Available The unusually high quality of census data for large waterbirds in Europe facilitates the study of how population change varies across a broad geographical range and relates to global change. The wintering population of the greylag goose Anser anser in the Atlantic flyway spanning between Sweden and Spain has increased from 120 000 to 610 000 individuals over the past three decades, and expanded its wintering range northwards. Although population sizes recorded in January have increased in all seven countries in the wintering range, we found a pronounced northwards latitudinal effect in which the rate of increase is higher at greater latitudes, causing a constant shift in the centre of gravity for the spatial distribution of wintering geese. Local winter temperatures have a strong influence on goose numbers but in a manner that is also dependent on latitude, with the partial effect of temperature (while controlling for the increasing population trend between years being negative at the south end and positive at the north end of the flyway. Contrary to assumptions in the literature, the expansion of crops exploited by greylag geese has made little contribution to the increases in population size. Only in one case (expansion of winter cereals in Denmark did we find evidence of an effect of changing land use. The expanding and shifting greylag population is likely to have increasing impacts on habitats in northern Europe during the course of this century.

    The aim of the trial was to explore the nutritional value of amaranth meal and the differences of different methods and breeds to determine the true metabolic energy and the conventional nutrient-efficiency of it. 24 healthy adult Wulong (mini-type) and Qingnong gray (large-scale) male geese were selected. The geese were divided into four treatment groups, with 6 geese in each group. Every goose was forced to feed 80 g per day. This trial adopted the method of total feces collection. Therefore amaranth meal was an ideal crude fiber feed for goose. It was better to be forced to feed single feedstuff with microelement and vitamin when evaluating the value of amaranth meal. There were some differences in the utilization of nutrition between the two breeds of geese.%为了探索籽粒苋对鹅的营养价值以及不同方法不同鹅品种对其真代谢能、常规养分利用效果与差异,分别选取健康成年五龙鹅(小型)和青农灰鹅(大型)公鹅各24只,各设4个处理组,每个处理组6只,试验鹅单笼饲养,每天强饲80 g,试验采用全收粪法.试验结果表明,籽粒苋对鹅是一种较为理想的粗纤维饲料;对籽粒苋进行营养价值评定时,采用强饲并添加维生素和微量元素的方法最好;两品种之间对籽粒苋的真代谢能及常规养分的利用率具有一定的差异.

    The bar-headed goose is currently one of the most popular species for rare birds breeding in China. However, bar-headed geese in captivity display a reduced reproductive rate. The gut microbiome has been shown to influence host factors such as nutrient and energy metabolism, immune homeostasis and reproduction. It is therefore of great scientific and agriculture value to analyze the microbial communities associated with bar-headed geese in order to improve their reproductive rate. Here we describe the first comparative study of the gut microbial communities of bar-headed geese in three different breeding pattern groups by 16SrRNA sequences using the Illumina MiSeq platform. The results showed that Firmicutes predominated (58.33%) among wild bar-headed geese followed by Proteobacteria (30.67%), Actinobacteria (7.33%) and Bacteroidetes (3.33%). In semi-artificial breeding group, Firmicutes was also the most abundant bacteria (62.00%), followed by Bacteroidetes (28.67%), Proteobacteria (4.20%), Actinobacteria (3.27%) and Fusobacteria (1.51%). The microbial communities of artificial breeding group were dominated by Firmicutes (60.67%), Fusobacteria (29.67%) and Proteobacteria (9.33%). Wild bar-headed geese had a significant higher relative abundance of Proteobacteria and Actinobacteria, while semi-artificial breeding bar-headed geese had significantly more Bacteroidetes. The semi-artificial breeding group had the highest microbial community diversity and richness, followed by wild group, and then the artificial breeding group. The marked differences of genus level group-specific microbes create a baseline for future bar-headed goose microbiology research.

    2002-01-01

    Full Text Available Canada's postsecondary institutions are becoming increasingly involved with technology enhanced learning, generally under the rubric of distance education. Growth and activity in distance education stems from rapid developments in communication and information technologies such as videoconferencing and the Internet. This case study focuses on the use of new technologies, primarily within the context of higher education institutions operating in Canada's English speaking provinces. Capitalising on the interactive capabilities of "new" learning technologies, some distance education providers are starting to behave more like conventional educational institutions in terms of forming study groups and student cohorts. Conversely, new telecommunications technologies are having a reverse impact on traditional classroom settings, and as a result conventional universities are beginning to establish administrative structures reflective of those used by distance education providers. When viewed in tandem, these trends reflect growing convergence between conventional and distance learning modes, leading to the hybridisation of higher education in Canada.

    Willms Allan R

    2008-02-01

    Full Text Available Abstract Background Hepatitis A (HA is a low-incidence, non-endemic disease in Canada and the United States (US. However, a large difference in HA incidence between Canada and HA-endemic countries has made travel an important contributor to hepatitis A prevalence in Canada. There is also a (smaller incidence differential between Canada and the US. Although the US has only moderately higher HA incidence, the volume of travel by Canadians to the US is many times higher than travel volume to endemic countries. Hence, travel to the US may constitute a source of low to moderate risk for Canadian travelers. To our knowledge, travel to the US has never been included as a potential risk factor for HA infection in Canadian epidemiologic analyses. The objective of this study was to use dynamic models to investigate the possible effects on hepatitis A incidence in Canada due to (1 implementing vaccination in the US, and (2 varying the volume of travel by Canadians to the US. Methods We developed and analyzed age-structured compartmental models for the transmission and vaccination of hepatitis A, for both Canada and the US. Models were parameterized using data on seroprevalence, case reporting, and travel patterns. The potential effect of hepatitis A prevalence in the US on hepatitis A prevalence in Canada was captured through a term representing infection of Canadians due to travel in the US. Results The model suggests that approximately 22% of HA cases in Canada in the mid 1990s may have been attributable to travel to the US. A universal vaccination programme that attained 70% coverage in young children in the US in the mid 1990s could have reduced Canadian incidence by 21% within 5 years. Conclusion Since not all necessary data were available to parameterize the model, the results should be considered exploratory. However, the analysis shows that, under plausible assumptions, the US may be more important for determining HA prevalence in Canada than is

  8. Action plan for electric mobility in Canada

    International Nuclear Information System (INIS)

    Electric mobility is an important emerging industry in Canada, where there is significant expertise in electric and hybrid vehicles, batteries, hybrid technologies, grid-connected technologies and fuel cell vehicles. This paper presented a case for the formation of Electric Mobility Canada, a proposed network of private companies and public sector agencies that aims to stimulate industry and provide support to government agencies involved with meeting Canada's obligations under the Kyoto Protocol, as well as in new industry sectors. The environmental, health, economic and industrial benefits of electric mobility were outlined. Current programs for electric mobility were reviewed, and details of financial incentives and initiatives were presented. An overview of electric mobility programs in the United States and Europe was provided. Research and development needs were evaluated. The former Electric Vehicle Association of Canada was discussed. An organizational structure for the proposed network was presented, along with a mission statement and outline of future goals. Recommendations for the future of the network included identifying short and long-term market opportunities for electric mobility technologies for all surface transport modes in Canada; determining research and development needs and appropriate funding and investment opportunities; determining other actions necessary to allow the electric mobility industry to play a growing role in meeting Canada's transport needs; and raising public awareness of the importance of electric mobility trends. It was concluded that the federal government should be approached for start-up funds for the network, which will be followed by further investment from provincial and business interests once the network is in place and functioning. 84 refs

    The first North American outbreak of highly pathogenic avian influenza (HPAI) involving a virus of Eurasian A/goose/Guangdong/1/1996 (H5N1) lineage began in the Fraser Valley of British Columbia, Canada in late November 2014. A total of 11 commercial and 1 non-commercial (backyard) operations were infected before the outbreak was terminated. Control measures included movement restrictions that were placed on a total of 404 individual premises, 150 of which were located within a 3 km radius of an infected premise(s) (IP). A complete epidemiological investigation revealed that the source of this HPAI H5N2 virus for 4 of the commercial IPs and the single non-commercial IP likely involved indirect contact with wild birds. Three IPs were associated with the movement of birds or service providers and localized/environmental spread was suspected as the source of infection for the remaining 4 IPs. Viral phylogenies, as determined by Bayesian Inference and Maximum Likelihood methods, were used to validate the epidemiologically inferred transmission network. The phylogenetic clustering of concatenated viral genomes and the median-joining phylogenetic network of the viruses supported, for the most part, the transmission network that was inferred by the epidemiologic analysis.

Hub equipment and 3000 mobile data terminals were supplied. Over the satellite tests were performed. The mobile data service provides full two way digital messaging automatic vehicle location and fleet management services. The second phase is to construct, launch and make operational the MSAT satellite and associated network control facilities. The implementation is examined of the mobile data service in Canada, including the technical description. Marketing and applications are also examined.

  11. The nuclear ingredient in Canada's industrialization

    International Nuclear Information System (INIS)

    The energy scene in Canada has been confused by a changing industrial and economic pattern, a proliferation of energy options, a conflict of energy priorities, and possibly a media and anti-nuclear inspired perception that electricity is expensive and not a good substitute for oil. In spite of an economic down-turn, in 1982-83 five new CANDU reactors with a combined capacity of 3000 MW were completed in Canada. Opportunities exist for increased use of electricity both in households and in industry. The benefits of nuclear power have extended beyond a reliable and economic energy supply to research advances, job creation, and the overall industrial development of the country

    1991-11-01

    Ninety-four Canadian-born psychiatric patients who committed suicide were compared with 23 foreign-born patients committing suicide in Canada. East Europeans were over-represented, and significant differences were found in the age distribution, stress, level of education, social isolation, and methods of suicide. Most foreign-born patients had come to Canada for family or economic reasons but were unemployed, with poor social integration. Employment, housing, education, social integration and a support network seem to be important in preventing these deaths. Cultural evaluation of the patient and early intervention is recommended.

    It is postulated that disease is a product of adverse habitats. Overpopulation causes overutilization of food supplies, which results in malnutrition and a decrease in resistance to diseases. Examples of such ecological relationships in populations of Canada geese, California quail, red grouse, deer, rabbits, voles, mice and lemmings are presented.

  1. The effect of plants with novel traits (PNT) regulation on mutation breeding in Canada

    International Nuclear Information System (INIS)

    In 1988 the Parliament of Canada passed the Canadian Environmental Protection Act (CEPA) into law. Within this Act is a definition for biotechnology which reads 'the application of science and engineering in the direct or indirect use of living organisms or parts or products of living organisms in their natural or modified forms'. The definition was placed in CEPA to deal with concerns regarding Genetically Modified Organisms (GMOs) and would allow Environment Canada to regulate all GMOs. In response to CEPA the Canadian Food Inspection Agency (CFIA), which is responsible for registration of plant varieties in Canada, developed the concept of a Plant with Novel Traits (PNT) defined as 'a plant variety possessing a characteristic that is intentionally selected or created through a specific genetic change and is either not previously associated with a distinct and stable population of the cultivated plant species in Canada or expressed outside the normal range of a similar existing characteristic in the plant species'. Not only does this definition capture GMOs it also includes induced mutations, natural mutations and exotic germplasm that have not previously been grown in Canada. It is, as CFIA has argued, a system that is product not process based. However, apart from questions regarding the novelty of traits in new plant varieties, breeders are asked by CFIA to identify the process used to develop the trait or traits in question. Field trials involving breeding lines with a PNT may be subject to confined testing. This conference celebrates 70 years of unconfined development and testing of induced plant mutations. This regulation is time consuming, expensive and an innovation barrier for Canadian plant breeding. It can only be hoped that other nations, and particularly those that have successfully used induced mutations, will not emulate Canada's approach. (author)

  4. Recent developments in Canada's climate change program

    International Nuclear Information System (INIS)

    This paper surveys Canada's official response to the responsibilities it took on with the Kyoto Protocol. In order to meet Kyoto targets for the timeframe 2008-2012, greenhouse gas emissions need to be reduced by 33 percent below what they currently are. Two billion Canadian dollars have been allocated to this effort. The government of Canada's official stance is that carbon dioxide levels have been rising more rapidly than at any other time in the last half million years. Canada's main efforts in the mining and minerals sector have been to find a replacement for sulphur hexafluoride, reduce emissions of perfluorocarbons, and demonstrate the use of hydrogen as a fuel for underground mining vehicles. According to the author, the most important contribution has been the use of supplementary cementing material such as fly ash, ash, and ground blast furnace slag. These materials have partially replaced cement in concrete. Canada expects to reduce carbon dioxide emissions this way by about 1.5 million tonnes per year. EcoSmart, a non-profit organization, is the main vehicle for this effort. 8 refs., 7 figs

  6. Workplace health and safety: report from Canada.

    Science.gov (United States)

    Sass, R

    1986-01-01

    This article represents a critical analysis of the major policy responses to workplace health and safety in Canada. It examines the deficiencies inherent in the legislative development of Joint Health and Safety Committees in most Canadian jurisdictions, the limitations regarding standard-setting of worker exposure to contaminants, and disincentive for employers to positively improve the workplace because of Workers Compensation legislation. Collective bargaining agreements in Canada have had only limited positive effects, while the ultimate legal sanction of criminal prosecution by the regulatory agencies has weakened enforcement and compliance of existing regulations. There has never been a successful criminal prosecution of an employer in Canada, even for multiple deaths. The article suggests the following four reasons for this "underdevelopment" of occupational health and safety in Canada: the concealment of the dimension of the incidence of industrial disease based on Workers Compensation Board statistics; the application of an incorrect theory of causation of both industrial disease and injury by both managers and government administrators of occupational health and safety programs; the resistance of both senior and middle managers against increased worker participation in both work organization and job design questions; and the general "moral underdevelopment," rather than ignorance, of managers in favoring economic considerations or values at the expense of worker health and safety. In light of the magnitude of the problem and the deficiencies of existing policy approaches, the author proposes the need for greater workplace democratization of production and industry as a necessary and sufficient reform of workplace health and safety.

    Abstract Statistics of migrants returning from Canada to Britain and re-registering for national insurance purposes are compared with labour force immigrants entering Canada between 1956 and 1965. Short and long-term indices are calculated which suggest that return migration has been increasing since 1960. A sample survey carried out in 1962-63 distinguishes three types of returning migrant: (a) quasi-migrants who originally planned to return to Britain; (b) permanent repatriates who originally intended to settle in Canada but now expect to remain in Britain; (c) transilient migrants who exhibit a high propensity to move backwards and forwards between two or more countries without becoming permanently rooted in anyone. The demographic, economic and social characteristics of the three types are described. A further comparison is made between migrants who plan to settle in Britain, those who intend to come back again to Canada, and those who are uncertain of their future plans or who intend to move on to a third country.

  12. Petro-Canada annual report, 1991

    International Nuclear Information System (INIS)

    Petro-Canada is Canada's national energy corporation, formed by an Act of Parliament in 1975. Operations began in January 1976. In 1991, Petro-Canada became a public company, issuing 19.5% of its common shares for net proceeds of $523 million. Heavy losses in the first half of the year were driven by price volatility following the Persian Gulf war. Cash flow return on capital employed was 7.2%, and a net loss of $598 million was posted. The Klua gas field was brought on stream only 30 months after discovery, an important gas discovery was made in British Columbia, and production and sales of natural gas increased. This annual report presents a corporate profile, a statement of corporate responsibility, and the year's activities in production and sales of natural gas, synthetic and natural crude oil and gasoline. Details are also provided of Petro-Canada's financial and operational restructuring in view of the declining revenues being obtained.

    Full Text Available To assess the risk of hepatitis C in Canada and to predict the burden that this disease may pose to the Canadian society in the near future, expected numbers of persons at different stages of the disease currently and in the next decade were estimated by simulation using a published hepatitis C natural history model with no treatment effect being applied. Based on the estimate of 240,000 persons who are currently infected with the hepatitis C virus in Canada, the simulation analysis demonstrated that the number of hepatitis C cirrhosis cases would likely increase by 92% from 1998 to the year 2008. It was also projected that the number of liver failures and hepatocellular carcinomas related to hepatitis C would increase by 126% and 102%, respectively, in the next decade. The number of liver-related deaths associated with hepatitis C is expected to increase by 126% in 10 years. The medical and social care systems in Canada may not be ready to support these large increases. These results highlight the importance of both the control of disease progression of hepatitis C virus-infected persons and the primary prevention of hepatitis C infections in Canada.

Phenological observations were carried out on the plants growing on alluvial soil developed from light loam in Zakrz6w near Tarnobrzeg. It was proved that phenological development of Canada thistle, during broad-bean vegetation, depended on course of weather conditions and method of crop care. Emergence of the weed occurred earlier than broad-bean plants during warm and rather dry seasons. In every vegetation period, emergence and early vegetation stage (to 4 leaves seedling of Canada thistle lasted about 3 months, until broad-bean got full pod setting. During wet and cold season (in 2001 the weed emerged also early under herbicide (Afalon 1,5 kg ha-1 condition.

    Canada Basin of the Arctic Ocean is the least studied ocean basin in the World. Marine seismic field programs were conducted over the past 6 years using Canadian and American icebreakers. These expeditions acquired more than 14,000 line-km of multibeam bathymetric and multi-channel seismic reflection data over abyssal plain, continental rise and slope regions of Canada Basin; areas where little or no seismic reflection data existed previously. Canada Basin is a turbidite-filled basin with flat-lying reflections correlateable over 100s of km. For the upper half of the sedimentary succession, evidence of sedimentary processes other than turbidity current deposition is rare. The Canadian Archipelago and Beaufort Sea margins host stacked mass transport deposits from which many of these turbidites appear to derive. The stratigraphic succession of the MacKenzie River fan is dominated by mass transport deposits; one such complex is in excess of 132,000 km2 in area and underlies much of the southern abyssal plain. The modern seafloor is also scarred with escarpments and mass failure deposits; evidence that submarine landsliding is an ongoing process. In its latest phase of development, Canada Basin is geomorphologically confined with stable oceanographic structure, resulting in restricted depositional/reworking processes. The sedimentary record, therefore, underscores the significance of mass-transport processes in providing sediments to oceanic abyssal plains as few other basins are able to do.

TransCanada's pipeline system transports natural gas and crude oil from Western Canada Sedimentary Basin to North America's major energy markets. Net earnings from continuing operations for 1998, before unusual charges, were $575 million ($ 355 million after unusual charges) compared to $522 million for 1997. Solid performances from the energy transmission and international business, when compared to 1997, were more than offset by a decreased contribution from energy processing. TransCanada recorded integration costs of $166 million, after tax, related to the merger with NOVA in 1998, which was the major operational accomplishment during the year, creating a seamless economic energy delivery, processing and marketing system from the wellhead to the market. tabs., figs

    Gray, Laura K.; Andreas Hamann

    2011-01-01

    BACKGROUND: Commercial forestry programs normally use locally collected seed for reforestation under the assumption that tree populations are optimally adapted to local environments. However, in western Canada this assumption is no longer valid because of climate trends that have occurred over the last several decades. The objective of this study is to show how we can arrive at reforestation recommendations with alternative species and genotypes that are viable under a majority of climate cha...

  17. Framing the issue of ageing and health care spending in Canada, the United Kingdom and the United States.

    Gusmano, Michael K; Allin, Sara

    2014-07-01

    Political debates about the affordability of health care programmes in high-income countries often point to population ageing as a threat to sustainability. Debates in the United States, in particular, highlight concerns about intergenerational equity, whereby spending on older people is perceived as a threat to spending on the young. This paper compares how the problem of health spending is defined in Canada, the United Kingdom and the United States by presenting the results of a content analysis of print media during the period 2005-2010. We found that population ageing was cited as an important source of health care cost increases in all three countries but was cited less frequently in Canadian newspapers than in the UK or US papers. Direct claims about intergenerational equity are infrequent among the articles we coded, but newspaper articles in the United States were more likely than those in Canada and the United Kingdom to claim that of high health care spending on older people takes resources away from younger people. In Canada a much larger percentage of articles in our sample either claimed that high health care spending is crowding out other types of government expenditure. Finally, we found that almost no articles in the United States challenged the view that population ageing causes health care spending, whereas in both Canada and the United Kingdom a small, but steady stream of articles challenged the idea that population ageing is to blame for health care spending increases.

  18. Seabirds and Atlantic Canada's ship-source oil pollution : impacts, trends, and solutions

    International Nuclear Information System (INIS)

    It is estimated that 300,000 seabirds die annually in Atlantic Canada as a result of illegal discharges of oil from ships. Chronic oil pollution along the southeast coast of Newfoundland has not been reduced in the last 20 years. The species most affected is the thick-billed murre which over winters on the Grand Banks of Newfoundland and breeds in the Canadian Arctic. Populations of the bird may decline in the next 2 decades if current mortality levels do not decrease. It was argued that fines and enforcement efforts in Atlantic Canada are lax compared to other countries and many ship operators dump their bilges in the coastal areas of Atlantic Canada. The World Wild Life Fund recommends that Canada follow the example of other countries and increase year-round enforcement, impose higher fines, and establish a convenient on-land oil disposal facility. These simple measures could reduce bilge-oil dumping at sea. 78 refs., 4 tabs., 5 figs

    Investigations by the United States Geological Survey of Ground Water in the Southern border area of the Snake Rive Plain, south of the Snake River, a re concerned at the present time with delineation of the principal ground-water districts, the extent and location of existing ground-water developments, the possibilities for additional development, and the effects of ground-water development on the regimen of streams and reservoirs whose waters are appropriate for beneficial use. The lower part of the Goose Creek Basin is one of the important ground-water districts of the southern plains area and there are substantial but spotty developments of ground water for irrigation in the basin. Several thousand irrigable acres that are now dry could be put under irrigation if a dependable supply of ground water could be developed. The relations of the ground-water reservoirs to the regime of the Snake River and Goose Cree, and to the large body of ground water in the Snake River Plain north of the Snake, are poorly known. A large amount of geologic and hydrologic study remains to be done before those relations can be accurately determined. Investigations will be continued in the future but file work and preparation of a comprehensive report inevitably will be delayed. Therefore the available records are presented herein in order to make them accessible to farmers, well drillers, government agencies, and the general public. Interpretation of the records is not attempted in this report and is deferred pending the accumulation of additional and quantitative information. The data summarized herein include records of the locations and physical characteristics of wells, the depth to water in wells, fluctuations of water levels in observation wells, and estimated rates and volumes of seasonal ans yearly ground-water pumpage for irrigation, municipal, and other uses.

  5. Changing air mass frequencies in Canada: potential links and implications for human health.

    Science.gov (United States)

    Vanos, J K; Cakmak, S

    2014-03-01

    Many individual variables have been studied to understand climate change, yet an overall weather situation involves the consideration of many meteorological variables simultaneously at various times diurnally, seasonally, and yearly. The current study identifies a full weather situation as an air mass type using synoptic scale classification, in 30 population centres throughout Canada. Investigative analysis of long-term air mass frequency trends was completed, drawing comparisons between seasons and climate zones. We find that the changing air mass trends are highly dependent on the season and climate zone being studied, with an overall increase of moderate ('warm') air masses and decrease of polar ('cold') air masses. In the summertime, general increased moisture content is present throughout Canada, consistent with the warming air masses. The moist tropical air mass, containing the most hot and humid air, is found to increase in a statistically significant fashion in the summertime in 46% of the areas studied, which encompass six of Canada's ten largest population centres. This emphasises the need for heat adaptation and acclimatisation for a large proportion of the Canadian population. In addition, strong and significant decreases of transition/frontal passage days were found throughout Canada. This result is one of the most remarkable transition frequency results published to date due to its consistency in identifying declining trends, coinciding with research completed in the United States (US). We discuss relative results and implications to similar US air mass trend analyses, and draw upon research studies involving large-scale upper-level air flow and vortex connections to air mass changes, to small-scale meteorological and air pollution interactions. Further research is warranted to better understand such connections, and how these air masses relate to the overall and city-specific health of Canadians.

  6. Canada's climate change policy in context

    International Nuclear Information System (INIS)

    Climate change has a wide range of implications for the health, well-being, and economic prospects for Canadians, and for the ecological systems that sustain life on this planet. The overwhelming scientific opinion, world leaders and even a growing number of corporate leaders now agree that the Earth is undergoing a significant and unusual warming period as a result of the build-up of greenhouse gases in the atmosphere. There is also wide agreement that much of this build-up is anthropogenic, and that a global effort is required to slow this trend. Because climate change is a global problem, it requires global solutions by way of reduction in global greenhouse gas emissions. In this context, the Kyoto Agreement of 1997 constitutes a major breakthrough, even though it takes only a small step towards towards altering the human impact on global climate. Although some 80 states, plus the European Union signed the Kyoto Protocol, it remains unclear when it will come into force because the majority of states have failed to ratify it, pending the resolution of a variety of technical and operational details. Canada is the second highest emitter of greenhouse gases (16 tonnes per capita, compared to world average of 3.6 tonnes per capita). This, combined with Canada's foreign policy goals of playing a leading role in taking action and preserving its reputation as an honest broker, makes the challenge of meeting Canada's Kyoto commitments especially pressing. The purpose of this paper is to explain Canada's climate change policy in the context of these international and domestic pressures. The paper identifies the main climate change-related policy challenges, international responses to date and the constraints and opportunities open to Canada in the light of its economy, its federalist political structure, and place in the world as a middle power, as well as its geographic situation, natural resources and environmental endowment. There is a detailed discussion of the Kyoto

    This article provides information on Alzheimer's disease and other dementias, using the 2010/2011 Canadian Community Health Survey, the 2011/2012 Survey of Neurological Conditions in Institutions in Canada, and the 2011 Survey on Living with Neurological Conditions in Canada. Among Canadians aged 45 or older, an estimated 0.8% in private households and 45% in long-term residential care facilities had a diagnosis of dementia. Prevalence rose with age. The vast majority of people with dementia in private households received assistance with medical care (81%), housework and home maintenance (83%), meal preparation (88%), emotional support (90%), transportation (92%), and managing care (92%). Among those receiving assistance, 85% relied, at least in part, on family, friends or neighbours. The primary caregiver tended to be a spouse (46%) or an adult child (44%), most of whom were daughters (71%). The majority of primary caregivers lived in the same household (83%) and provided daily care (86%). PMID:27192206

    International Nuclear Information System (INIS)

    The carbon disclosure project conducts an annual survey to determine the strategies and actions of major cap companies in relation to climate change. This report discussed initiatives implemented by Canada's largest companies to prepare for a carbon-constrained future. The report documented results from 97 companies. The aim of the report was to help companies make use of the disclosures as reference points for future carbon markets and regulations relating to reporting requirements. Results of the survey demonstrated that Canada's low-carbon and high-carbon impact sectors have implemented several significant initiatives and best practices for operations. However, widespread engagement in a comprehensive manner has yet to be achieved. Many respondents were in the process of developing a more balanced risk-opportunity agenda in relation to climate change, and nearly half of all respondents have implemented governance arrangements or personal incentives in both both the high-carbon and low-carbon impact sectors. 5 tabs., 26 figs.

    The history of providing public information on nuclear energy in Canada for more than 40 years is described. Information centers are part of all nuclear power plants and they receive many thousands of visitors each year. Until the 1970s public information programs were relatively easy. There was a lot of interest in nuclear energy, and there was little debate about it or opposition to it. But times have changed, and Canadian public information strategies and tactics have evolved to meet challenge of answering increasing public concerns. In the past 20 years Canada has gone through three phases in relationship with the public: information, communication, participation. Activities on implementation of these phases are outlined

    Ostriches farmed in Canada often have particular behavioral problems that are brought about by periods of extreme confinement during winter months. Although they still perform normal species specific behaviors such as twirling, kanteling, and kicking, abnormal behaviors become prominent when excessively confined. They include for all age groups of ostriches, feather-picking, behavioral stargazing, dietary indiscretion, pica, anorexia and adipsia, and aggression. These abnormal behaviors initiated by inadequate husbandry techniques, eventually become medical problems because of their severity. PMID:8809393

  20. Nuclear fuel waste policy in Canada

    International Nuclear Information System (INIS)

    The 1996 Policy Framework for Radioactive Waste established the approach in Canada for dealing with all radioactive waste, and defined the respective roles of Government and waste producers and owners. The Policy Framework sets the stage for the development of institutional and financial arrangements to implement long-term waste management solutions in a safe, environmentally sound, comprehensive, cost-effective and integrated manner. For nuclear fuel waste, a 10-year environmental review of the concept to bury nuclear fuel waste bundles at a depth of 500 m to 1000 m in stable rock of the Canadian Shield was completed in March 1998. The Review Panel found that while the concept was technically safe, it did not have the required level of public acceptability to be adopted at this time as Canada's approach for managing its nuclear fuel waste. The Panel recommended that a Waste Management Organization be established at arm's length from the nuclear industry, entirely funded by the waste producers and owners, and that it be subject to oversight by the Government. In its December 1998 Response to the Review Panel, the Government of Canada provided policy direction for the next steps towards developing Canada's approach for the long-term management of nuclear fuel waste. The Government chose to maintain the responsibility for long-term management of nuclear fuel waste close with the producers and owners of the waste. This is consistent with its 1996 Policy Framework for Radioactive Waste. This approach is also consistent with experience in many countries. In addition, the federal government identified the need for credible federal oversight. Cabinet directed the Minister of NRCan to consult with stakeholders, including the public, and return to ministers within 12 months with recommendations on means to implement federal oversight.
