Clavulanic acid (CA) is a powerful inhibitor of the beta-lactamases, enzymes produced by bacteria resistants to penicillin and cefalosporin. This molecule is produced industrially by strains of Streptomyces clavuligerus in complex media which carbon and nitrogen resources are supplied by inexpensive compounds still providing high productivity. The genetic production improvement using physical and chemical mutagenic agents is an important strategy in programs of industrial production development of bioactive metabolites. However, parental strains are susceptible to loss of their original productivity due genetic instability phenomenona. In this work, some S. clavuligerus mutant strains obtained by treatment with UV light and with MMS are compared with the wild type (Streptomyces clavuligerus ATCC 27064). The results indicated that the random mutations originated some strains with different phenotypes, most divergent demonstrated by the mutants strains named AC116, MMS 150 and MMS 54, that exhibited lack of pigmentation in their mature spores. Also, the strain MMS 150 presented a larger production of CA when cultivated in semi-synthetics media. Using other media, the wild type strain obtained a larger CA production. Besides, using the modifed complex media the MMS 150 strain showed changes in its lipolitic activity and a larger production of CA. The studies also allowed finding the best conditions for a lipase activity exhibited by wild type S. clavuligerus and the MMS150 mutant.

Frederick U. Ozor

2014-09-01

Full Text Available Public research institutions and scientists are principal actors in the production and transfer of scientific knowledge, technologies and innovations for application in industry as well for social and economic development. Based on the relevance of science and technology actors, the aim of this study was to identify and explain factors in research governance that influence scientific knowledge production and to contribute to empirical discussions on the impact levels of different governance models and structures. These discussions appear limited and mixed in the literature, although still are ongoing. No previous study has examined the possible contribution of the scientific committee model of research governance to scientific performance at the individual level of the scientist. In this context, this study contributes to these discussions, firstly, by suggesting that scientific committee structures with significant research steering autonomy could contribute not only directly to scientific output but also indirectly through moderating effects on research practices. Secondly, it is argued that autonomous scientific committee structures tend to play a better steering role than do management-centric models and structures of research governance.

Wild boars, because of their large size and ability to survive adverse conditions, are usually used to cross with domestic breeds to improve the quality of domesticated pigs. This study aimed to investigate the growth performance, slaughter performance, and meat quality of Ziwuling crossbred pigs. Crossbred pigs in four groups (n = 8 per group, 4 boars and 4 sows, all aged 100 days), F 1 [wild × B (Bamei)], F 1  × B, F 1  × Y (Yorkshire), and F 1  × F 1 , were selected at a commercial pig farm. Growth performance, slaughter performance, and meat quality of these crossbred pigs were determined. Characteristics of fatty acids, amino acids, and longissimus muscle fiber in relation to growth, carcass, and meat quality traits were also investigated. Pigs in F 1 and F 1  × F 1 groups had lower average daily weight gain, water and storage loss rates, larger meat color score, higher muscle amino acid levels, larger muscle fiber diameter, and higher ratio of flavor amino acids to unsaturated fatty acids compared to other groups. Crossbred pigs with higher rate of wild boar's consanguinity could improve production performance, slaughter performance, and meat quality. Thus, crossbreeding wild pig with domestic breeds might be an effective method to improve meat quality and flavor.

Declining Use of Wild Resources by Indigenous Peoples of the Ecuadorian Amazon.

Gray, Clark L; Bozigar, Matthew; Bilsborrow, Richard E

2015-02-01

Wild product harvesting by forest-dwelling peoples, including hunting, fishing, forest product collection and timber harvesting, is believed to be a major threat to the biodiversity of tropical forests worldwide. Despite this threat, few studies have attempted to quantify these activities across time or across large spatial scales. We use a unique longitudinal household survey (n = 480) to describe changes in these activities over time in 32 indigenous communities from five ethnicities in the northern Ecuadorian Amazon. To provide insight into the drivers of these changes, we also estimate multilevel statistical models of these activities as a function of household and community characteristics. These analyses reveal that participation in hunting, fishing, and forest product collection is high but declining across time and across ethnicities, with no evidence for a parallel decline in resource quality. However, participation in timber harvesting did not significantly decline and there is evidence of a decline in resource quality. Multilevel statistical models additionally reveal that household and community characteristics such as ethnicity, demographic characteristics, wealth, livelihood diversification, access to forest, participation in conservation programs and exposure to external markets are significant predictors of wild product harvesting. These characteristics have changed over time but cannot account for declining participation in resource harvesting. This finding suggests that participation is declining due to changes in the regional-scale social and economic context, including urbanization and the expansion of government infrastructure and services. The lesson for conservationists is that macro-scale social and economic conditions can drive reductions in wild product harvesting even in the absence of successful conservation interventions.

Differential iridoid production as revealed by a diversity panel of 84 cultivated and wild blueberry species.

Full Text Available Cultivated blueberry (Vaccinium corymbosum, Vaccinium angustifolium, Vaccinium darrowii, and Vaccinium virgatum is an economically important fruit crop native to North America and a member of the Ericaceae family. Several species in the Ericaceae family including cranberry, lignonberry, bilberry, and neotropical blueberry species have been shown to produce iridoids, a class of pharmacologically important compounds present in over 15 plant families demonstrated to have a wide range of biological activities in humans including anti-cancer, anti-bacterial, and anti-inflammatory. While the antioxidant capacity of cultivated blueberry has been well studied, surveys of iridoid production in blueberry have been restricted to fruit of a very limited number of accessions of V. corymbosum, V. angustifolium and V. virgatum; none of these analyses have detected iridoids. To provide a broader survey of iridoid biosynthesis in cultivated blueberry, we constructed a panel of 84 accessions representing a wide range of cultivated market classes, as well as wild blueberry species, and surveyed these for the presence of iridoids. We identified the iridoid glycoside monotropein in fruits and leaves of all 13 wild Vaccinium species, yet only five of the 71 cultivars. Monotropein positive cultivars all had recent introgressions from wild species, suggesting that iridoid production can be targeted through breeding efforts that incorporate wild germplasm. A series of diverse developmental tissues was also surveyed in the diversity panel, demonstrating a wide range in iridoid content across tissues. Taken together, this data provides the foundation to dissect the molecular and genetic basis of iridoid production in blueberry.

From Product to Place-Spatializing governance in a commodified landscape.

van Oosten, Cora; Moeliono, Moira; Wiersum, Freerk

2018-07-01

This article analyzes the potential for landscape governance in large-scale commodity landscapes in Indonesia. It conceptualizes landscape governance as the spatialization of governance, which entails the interplay between natural-spatial conditions of place, public-private actor constellations, and policy responses. The article presents the case of a commodified oil palm landscape in West Kalimantan, where a potentially new type of landscape governance is emerging out of the experimental activities of an ecologically responsible commercial enterprise. It describes the development of a multifunctional concession as a process of productive bricolage involving the creative combination of different land uses within a single productive space. It also describes how such a multifunctional concession does not fit into existing policies, which are sectorally defined and embedded in sticky institutional frames. The formation of new public-private institutional arrangements needed for the development of multifunctional concessions is a difficult process, as it requires an alignment of contrasting discourses and an integration of sectorally-defined policy frames. If successful, it might facilitate the transition from multifunctional concessions to multifunctional landscapes. Such a fundamental change in land use and production relations however requires intensive stakeholder engagement and policy dialog. Indonesia's continuous decentralization process offers opportunities for this, as it increasingly provides institutional space at the landscape level, for public and private actors to explore common concerns, and craft public-private arrangements specific to the landscape.

Wild reindeer of Yakutia

1996-01-01

Full Text Available Three major herds of wild reindeer (Rangifer tarandus tarandus L., totaling over 200,000 animals, occur in the tundra and taiga of northern Yakutia. These herds have been expanding since the late 1950s and now occupy most of their historic range. In addition, several thousand wild reindeer occupy the New Siberian Islands and adjacent coastal mainland tundra, and there are about 60,000 largely sedentary forest reindeer in mountainous areas of the southern two-thirds of the province. Wild reindeer are commercially hunted throughout the mainland, and the production of wild meat is an important part of the economy of the province and of individual reindeer enterprises which produce both wild and domestic meat.

Genetic and phenotypic diversity of naturally isolated wild strains of Aspergillus niger with hyper glucose oxidase production

Full Text Available Glucose oxidase (GOx is the basic stone for many of biological industry worldwide. The improvement of GOx production basically depends on selection of hyper producer strain of Aspergillus niger. Selective isolation and screening for natural hyper producer strains of A. niger and sequence analysis of the GOD gene, which is responsible for production of the enzyme, are very effective approaches to investigate the naturally modified strains of A. niger with hyper productive capacity of GOx enzyme. The aims of the current study were selective isolation of naturally hyper GOx producing strains of A. niger and evaluation of their GOx activities under optimized parameters in the laboratory. Five wild Egyptian isolates of A. niger were screened for GOx and catalase activity using two types of modified basal liquid media. The GOx activity was evaluated by high throughout liquid phase system. The isolates showed a variable activity for GOx production ranged from 0 to 28.7 U.ml-1. One isolate coded Strain 7 was negative GOx producer on Vogel's broth medium in comparison to other isolates, while its GOx activity on Cazpek Dox was considered as positive (7.28 U.ml-1. It was concluded that GOx production is affected by three controllable factors – the basal media components, time of incubation, and the strain with its adaption to the media components‎. Also, the catalase activity was tested and it was produced with a different degree of variability, which may be reflected on GOx stability. GOD genes of these wild variant of A. niger were cloned and sequenced to determine intraspecies diversity of GOD between the wild variants. The comparison of isolated wild variants to other reference hyper GOx producer strains of A. niger was performed to determine if the GOD sequence analysis of these strains can be distinguished based on their GOx activity. This is the first report for isolation and detection of naturally A. niger hyper GOx-producer strains with

For decades, southern China has been considered to be an important source for emerging influenza viruses since key hosts live together in high densities in areas with intensive agriculture. However, the underlying conditions of emergence and spread of avian influenza viruses (AIV) have not been studied in detail, particularly the complex spatiotemporal interplay of viral transmission between wild and domestic ducks, two major actors of AIV epidemiology. In this synthesis, we examine the risks of avian influenza spread in Poyang Lake, an area of intensive free-ranging duck production and large numbers of wild waterfowl. Our synthesis shows that farming of free-grazing domestic ducks is intensive in this area and synchronized with wild duck migration. The presence of juvenile domestic ducks in harvested paddy fields prior to the arrival and departure of migrant ducks in the same fields may amplify the risk of AIV circulation and facilitate the transmission between wild and domestic populations. We provide evidence associating wild ducks migration with the spread of H5N1 in the spring of 2008 from southern China to South Korea, Russia, and Japan, supported by documented wild duck movements and phylogenetic analyses of highly pathogenic avian influenza H5N1 sequences. We suggest that prevention measures based on a modification of agricultural practices may be implemented in these areas to reduce the intensity of AIV transmission between wild and domestic ducks. This would require involving all local stakeholders to discuss feasible and acceptable solutions.

Full Text Available This article aims to identify the structure of governance in the Production Chain Chestnut of the Amazon state of Rondonia in order to know the relationship of its agents. We used secondary data source and qualitative approach, based on the collection of data resulting from the project on nontimber forest products (NTFPs, which included the cities of Costa Marques, Guajará-Mirim, Machadinho do Oeste, Porto Velho and Presidente Médici, located in the state of Rondônia. It was found that producers and middlemen pay a high cost for shipping, however, these costs is not just about the initial link of the chain, but to the end consumer to pay more for the product, due to the difficulties faced during the process. Furthermore, it was also evidenced the low price of the product received by producers and middlemen, however, the transactions show that there is no formal relationship between the parties, contracts are informal, the form of governance found most frequently is the way market.

Evaluating relationships between wild Skeena river sockeye salmon productivity and the abundance of spawning channel enhanced sockeye smolts.

Science.gov (United States)

Price, Michael H H; Connors, Brendan M

2014-01-01

The enhancement of salmon populations has long been used to increase the abundance of salmon returning to spawn and/or to be captured in fisheries. However, in some instances enhancement can have adverse impacts on adjacent non-enhanced populations. In Canada's Skeena watershed, smolt-to-adult survival of Babine Lake sockeye from 1962-2002 was inversely related to the abundance of sockeye smolts leaving Babine Lake. This relationship has led to the concern that Babine Lake smolt production, which is primarily enhanced by spawning channels, may depress wild Skeena (Babine and non-Babine) sockeye populations as a result of increased competition between wild and enhanced sockeye smolts as they leave their natal lakes and co-migrate to sea. To test this hypothesis we used data on Skeena sockeye populations and oceanographic conditions to statistically examine the relationship between Skeena sockeye productivity (adult salmon produced per spawner) and an index of Babine Lake enhanced smolt abundance while accounting for the potential influence of early marine conditions. While we had relatively high power to detect large effects, we did not find support for the hypothesis that the productivity of wild Skeena sockeye is inversely related to the abundance of enhanced sockeye smolts leaving Babine Lake in a given year. Importantly, life-time productivity of Skeena sockeye is only partially explained by marine survival, and likely is an unreliable measure of the influence of smolt abundance. Limitations to our analyses, which include: (1) the reliance upon adult salmon produced per spawner (rather than per smolt) as an index of marine survival, and (2) incomplete age structure for most of the populations considered, highlight uncertainties that should be addressed if understanding relationships between wild and enhanced sockeye is a priority in the Skeena.

Photosynthetic rate, RuBP Carboxylase activity, glycolate oxidase activity, malate dehydrogenase activity, specific leaf weight, harvest index and yield were estimated in the normal and 10 Krad dose treated M 2 plants of Vigna sublobata (wild), V. radiata and V. mungo (cultivars) with the objective of locating and utilizing productivity promoting gene assemblies as well as to understand the role of natural and artificial selections in moulding yield promoting gene combinations. The results suggest that there is higher photosynthetic rate and RuPB Case activity in the 10 Krad treated M 2 plants. There is lesser glycolate oxidase activity and malate dehydrogenase activity. There is also positive correlation among net leaf assimilation rate, RuBP Case activity, SLW, HI and yield. These observations imply that domestication accompanied by directional selection did a lter substantially the productivity traits and productivity promoting gene assemblies.

Pratter, S M; Eixelsberger, T; Nidetzky, B

2015-12-01

A novel Saccharomyces cerevisiae whole-cell biocatalyst for xylitol production based on Candida tenuis xylose reductase (CtXR) is presented. Six recombinant strains expressing wild-type CtXR or an NADH-specific mutant were constructed and evaluated regarding effects of expression mode, promoter strength, biocatalyst concentration and medium composition. Intracellular XR activities ranged from 0.09 U mgProt(-1) to 1.05 U mgProt(-1) but did not correlate with the strains' xylitol productivities, indicating that other factors limited xylose conversion in the high-activity strains. The CtXR mutant decreased the biocatalyst's performance, suggesting use of the NADPH-preferring wild-type enzyme when (semi-)aerobic conditions are applied. In a bioreactor process, the best-performing strain converted 40 g L(-1) xylose with an initial productivity of 1.16 g L(-1)h(-1) and a xylitol yield of 100%. The obtained results underline the potential of CtXR wild-type for xylose reduction and point out parameters to improve "green" xylitol production. Copyright © 2015 Elsevier Ltd.

Riedinger, Verena; Mitesser, Oliver; Hovestadt, Thomas; Steffan-Dewenter, Ingolf; Holzschuh, Andrea

2015-05-01

Mass-flowering crops may affect long-term population dynamics, but effects on pollinators have never been studied across several years. We monitored wild bees in oilseed rape fields in 16 landscapes in Germany in two consecutive years. Effects on bee densities of landscape oilseed rape cover in the years of monitoring and in the previous years were evaluated with landscape data from three consecutive years. We fit empirical data to a mechanistic model to provide estimates for oilseed rape attractiveness and its effect on bee productivity in comparison to the rest of the landscape, and we evaluated consequences for pollinator densities in consecutive years. Our results show that high oilseed rape cover in the previous year enhances current densities of wild bees (except for bumble bees). Moreover, we show a strong attractiveness of and dilution on (i.e., decreasing bee densities with increasing landscape oilseed rape cover) oilseed rape for bees during flowering in the current year, modifying the effect of the previous year's oilseed rape cover in the case of wild bees (excluding Bombus). As long as other factors such as nesting sites or natural enemies do not limit bee reproduction, our findings suggest long-term positive effects of mass-flowering crops on bee populations, at least for non-Bombus generalists, which possibly help to maintain crop pollination services even when crop area increases. Similar effects are conceivable for other organisms providing ecosystem services in annual crops and should be considered in future studies.

Domestication and sustainable production of wild crafted plants with special reference to the Chilean Maqui berry (Aristotelia chilensis

Directory of Open Access Journals (Sweden)

Vogel, Hermine

2016-07-01

Full Text Available The principle threats for sustainable production of wild collected medicinal plants are related to ecological factors, such as endemism, and botanical factors critical for survival, such as the collection of roots or barks or slow growing species. The sustainable way to produce raw material on a large scale would be species specific management of the wild resources that guarantees conservation of biodiversity, or bringing the species under cultivation. A checklist proposed by WHO, UICN and WWF (1993 indicates that domestication of any medicinal plant concerns plant selection and breeding, studies about propagation, cultivation techniques, plant protection, time of harvest, among others. The different domestication steps are illustrated for the Chilean maqui (Aristotelia chilensis, a wild tree whose fruits are demanded in increasing volumes by the international market because of its high antioxidant capacity. High yielding plants with good fruit quality have been selected from wild populations and accessions have been cultivated under different environmental conditions to select the most suitable genotypes for the establishment of commercial orchards.

Optimization of the cultivation conditions for mushroom production with European wild strains of Agaricus subrufescens and Brazilian cultivars.

2014-01-15

The almond mushroom Agaricus subrufescens (formerly Agaricus blazei or Agaricus brasiliensis) is cultivated at commercial level in Brazil and some Asian countries on local substrates and casing mixtures. Despite its tropical origin, A. subrufescens might be a seasonal option for mushroom growers in western countries, where some wild strains have been isolated. For this purpose, cultivation conditions were developed starting from the substrate and casing mixture commonly used for commercial production of the button mushroom Agaricus bisporus in France. The commercial compost, based on wheat straw and horse manure, used for A. bisporus and the casing mixture (peat and limestone) supplemented with fine sand proved efficient to grow A. subrufescens. Increasing the depth of the casing layer improved significantly the yield and time to fruiting. Daily variations in temperature did not markedly modify the yield. Significantly higher mushroom biomass was obtained with three wild European strains compared with three Brazilian cultivars. The very productive wild strain CA438-A gave mushrooms of size and dry matter content comparable to those of a cultivar. Commercial production of A. subrufescens can be developed in western countries on the wheat straw-based substrate commonly used for A. bisporus in these regions, by a simple modification of the casing mixture and maintaining the incubation temperature throughout the crop, which is expected to save energy during summer. Good yields were obtained cultivating European strains under optimised parameters. © 2013 Society of Chemical Industry.

Interaction of Wild Strains of Aspergilla with Aspergillus parasiticus ATCC15517 and Aflatoxin Production †

Science.gov (United States)

Martins, H. Marina; Almeida, Inês; Marques, Marta; Bernardo, Fernando

2008-01-01

Aflatoxins are secondary metabolites produced by some competent mould strains of Aspergillus flavus, A. parasiticus and A. nomius. These compounds have been extensively studied with regards to their toxicity for animals and humans; they are able to induce liver cancer and may cause a wide range of adverse effects in living organisms. Aflatoxins are found as natural contaminants of food and feed; the main line of the strategy to control them is based on the prevention of the mould growth in raw vegetable or during its storage and monitoring of each crop batch. Mould growth is conditioned by many ecological factors, including biotic ones. Hazard characterization models for aflatoxins in crops must take into consideration biotic interactions between moulds and their potential effects on growth development. The aim of this work is to study the effect of the biotic interaction of 14 different wild strains of Aspergilla (different species), with a competent strain (Aspergillus parasiticus ATCC 15517) using an in vitro production model. The laboratory model used was a natural matrix (humidified cracked corn), on which each wild strain challenged the aflatoxin production of a producer strain. Cultures were incubated at 28°C for 12 days and sampled at the 8th and 12th. Aflatoxin detection and quantification was performed by HPLC using a procedure with a MRPL = 1 μg/kg. Results of those interactive cultures revealed both synergic and antagonistic effects on aflatoxin biosynthesis. Productivity increases were particularly evident on the 8th day of incubation with wild strains of A. flavipes (+ 70.4 %), A. versicolor (+ 54.9 %) and A. flavus 3 (+ 62.6 %). Antagonistic effects were found with A. niger (− 69.5%), A. fumigatus (− 47.6 %) and A. terreus (− 47.6 %) on the 12th day.

Constraints on productivity of wild Nene or Hawaiian geese Branta sandvicensis

Science.gov (United States)

Banko, P.C.

1992-01-01

I investigated constraints on the productivity of wild Nene on Hawaii and Maui during 1978-81. These populations were composed largely of captive-reared birds. Recruitment of young was low. Of 140 breeding attempts, 36% resulted in successful nests and 7% produced fledglings. Annual productivity was limited because: 1) relatively few available pairs attempted to breed (58% on Hawaii; 46% on Maui), 2) average rate of nest success was low (44%), and 3) gosling survival was low nesting suggests that many females could not accumulate sufficient body reserves for egg-laying and incubation due to poor foraging conditions or poorly developed foraging skills. Nest failure was high due to predation on eggs and incubating females by the introduced mongoose. Gosling mortality was high because of poor foraging conditions near many nests, forcing broods to travel over rugged, volcanic terrain to distant rearing areas. In addition, some goslings were killed by predators. Nene populations would benefit most from improved foraging opportunities for adult females and goslings and from reduced predator populations.

Significant progress was attained in implementing the complex and challenging studies of wild steelhead Oncorhynchus mykiss production in Idaho. Study sites were selected and techniques were developed to collect the needed data in remote wilderness locations. Cursory examination of existing data provides indication that most wild steelhead stocks are under escaped, especially the Group B stocks. Abundance of wild steelhead is generally declining in recent years. The portable weir concept and electronic fish counting developed through this project have been well received by land owners and reviewing governmental agencies with less impact to the land, stream, and fishery resources than conventional permanent weirs

Schunko, Christoph; Grasser, Susanne; Vogl, Christian R

2015-06-30

Wild plant gathering becomes again a popular and fashionable activity in Europe after gathering practices have been increasingly abandoned over the last decades. Recent ethnobotanical research documented a diversity of gathering practices from people of diverse socio-economic and cultural backgrounds who gather in urban and rural areas. Few efforts were though made to study the motivations for gathering wild plants and to understand the resurgent popularity of wild plant gathering. This paper addresses the following research questions: (1) which motivations activate wild plant gatherers? (2) which motivation-types of gatherers exist in the Grosses Walsertal? (3) how do the motivations for gathering relate to the socio-demographic background of gatherers? Field research was conducted in the Grosses Walsertal, Austria in the years 2008 and 2009 in two field research periods. Thirty-six local farmers were first interviewed with semi-structured interviews. The motivations identified in these interviews were then included in a structured questionnaire, which was used to interview 353 residents of the valley. Pupils of local schools participated in the data collection as interviewers. Principal Component Analysis was used to categorize the motivations and to identify motivation-types of wild plant gatherers. Generalized Linear Models were calculated to identify relations between motivations and the socio-demographic background of gatherers. The respondents listed 13 different motivations for gathering wild plants and four motivations for not gathering. These 17 motivations were grouped in five motivation-types of wild plant gatherers, which are in decreasing importance: product quality, fun, tradition, not-gathering, income. Women, older respondents and homegardeners gather wild plants more often for fun; older respondents gather more often for maintaining traditions; non-homegardeners more frequently mention motivations for not gathering. The resurgent popularity of

Long-distance migrations of wildlife have been identified as important biological phenomena, but their conservation remains a major challenge. The Mongolian Gobi is one of the last refuges for the Asiatic wild ass (Equus hemionus) and other threatened migratory mammals. Using historic and current distribution ranges, population genetics, and telemetry data we assessed the connectivity of the wild ass population in the context of natural and anthropogenic landscape features and the existing network of protected areas. In the Mongolian Gobi mean biomass production is highly correlated with human and livestock density and seems to predict wild ass occurrence at the upper level. The current wild ass distribution range largely falls into areas below the 250 gC/m(2)/year productivity isoline, suggesting that under the present land use more productive areas have become unavailable for wild asses. Population genetics results identified two subpopulations and delineated a genetic boundary between the Dzungarian and Transaltai Gobi for which the most likely explanation are the mountain ranges separating the two areas. Home ranges and locations of 19 radiomarked wild asses support the assumed restricting effects of more productive habitats and mountain ranges and additionally point towards a barrier effect of fences. Furthermore, telemetry data shows that in the Dzungarian and Transaltai Gobi individual wild ass rarely ventured outside of the protected areas, whereas in the southeast Gobi asses only spend a small fraction of their time within the protected area network. Conserving the continuity of the wild ass population will need a landscape level approach, also including multi-use landscapes outside of protected areas, particularly in the southeast Gobi. In the southwest Gobi, allowing for openings in the border fence to China and managing the border area as an ecological corridor would connect three large protected areas together covering over 70,000 km(2) of wild ass

Use of femur bone density to segregate wild from farmed Dybowski's frog (Rana dybowskii).

Science.gov (United States)

Yang, Shu Hui; Huang, Xiao Ming; Xia, Rui; Xu, Yan Chun; Dahmer, Thomas D

2011-04-15

Wildlife has been utilized by humans throughout history and demand continues to grow today. Farming of wildlife can supplement the supply of wild-harvested wildlife products and, in theory, can reduce pressure on free-ranging populations. However, poached wildlife products frequently enter legal markets where they are fraudulently sold as farmed wildlife products. To effectively close this illegal trade in wild-captured wildlife, there is a need to discriminate wild products from farmed products. Because of the strong market demand for wild-captured frog meat and the resulting strong downward pressure on wild populations, we undertook research to develop a method to discriminate wild from farmed Dybowski's frog (Rana dybowskii) based on femur bone density. We measured femur bone density (D(f)) as the ratio of bone mass to bone volume. D(f) of wild frogs revealed a slightly increasing linear trend with increasing age (R(2)=0.214 in males and R(2)=0.111 in females, p=0.000). Wild males and wild females of age classes from 2 to ≥ 5 years had similar D(f) values. In contrast, 2-year-old farmed frogs showed significantly higher D(f) values (p=0.000) among males (mean D(f)=0.623 ± 0.011 g/ml, n=32) than females (mean D(f)=0.558 ± 0.011 g/ml, n=27). For both sexes, D(f) of wild frogs was significantly higher than that of farmed frogs (p=0.000). Among males, 87.5% (28 of 32 individuals) of farmed frogs were correctly identified as farmed frogs and 86.3% (69 of 80 individuals) of wild frogs were correctly identified as wild frogs. These results suggest that femur bone density is one reliable tool for discriminating between wild and farmed Dybowski's frog. This study also highlights a novel strategy with explicit forensic potential to discriminate wild from captive bred wildlife species. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Who greens the waves? Changing authority in the environmental governance of shipping and offshore oil and gas production

International Nuclear Information System (INIS)

Van Leeuwen, J.

2010-01-01

The marine environment is under serious pressure from human activities. The transboundary and large-scale nature of these threats require cooperation between states, and between states, industries and NGOs. Marine governance therefore becomes a breeding ground for innovation: multi-level and multi-actor governance and changing spheres of authority. This book applies the concept 'spheres of authority' to investigate the nature of these innovations in governing shipping and offshore oil and gas production. In the environmental governance of shipping, authority is shifting from states that own ships to states that own ports. The environmental governance of offshore oil and gas production shows a shared authority for developing and implementing policies between state and industry, but not a diminishing authority of the state.

The Governance of Indigenous Natural Products in Namibia: A Policy Network Analysis.

Ndeinoma, Albertina; Wiersum, K Freerk; Arts, Bas

2018-01-09

At the end of the 20th century, optimism existed that non-timber forest products (NTFPs) can form an integral part in conservation and development strategies. However, there is limited knowledge on how the different stakeholders could relate to the state or to each other in promoting commercialization of NTFPs. Applying the policy network as an analytical framework, we investigated the structural patterns of actor relations in the governance structure of indigenous natural products (INPs) in Namibia, to understand the implications of such relations on INP policy process. The findings indicate that the INP policy network in Namibia is multi-dimensional, consisting of the Indigenous Plant Task Team (IPTT)-the key governance structure for resource mobilization and information sharing; and functional relations which serve specific roles in the INP value chain. The existing relations have facilitated policy development particularly for heavily regulated species, such as devil's claw; but for other species, only incremental changes are observed in terms of small-scale processing facilities for value addition and exclusive purchase agreements for sustainable sourcing of INPs. Participation of primary producers, private actors and quality standardization bodies is limited in INPs governance structures, which narrow the scope of information sharing. Consequently, despite that the IPTT has fostered publicly funded explorative pilot projects, ranging from production to marketing of INPs, there are no clear guidelines how these projects results can be transferred to private entities for possible commercialization. Further collaboration and information sharing is needed to guide public sector relations with the private entities and cooperatives.

Ibrahim Usman

2013-07-01

Full Text Available Groundnut an important oil seed crop provides significant sources of cash through the sales of seed, cakes, oil and haulms. Groundnut plays an important role in the diets of rural populations. Groundnut pod yields from farmer’s field are low, averaging about 800 kg per ha, less than one-third the potential yield of 3000 kg per ha. This large gap is of concern and in view of this, the study was carried out to assess the socio economic characteristics of groundnut farmers, determine the level of profitability of groundnut production, the resource use efficiency as well as to find out problems encountered in groundnut production in Sabon-gari local government area. Seventy-nine farmers involved in groundnut production were randomly selected from the various farms located within the local government area. Data were collected using primary and secondary sources. To examine the profitability of groundnut production, the gross margin and cost benefit analysis were carried out. The result of the study shows that experienced farmers are less involved in groundnut production and most groundnut farmers are engaged in other form of businesses. The cost, availability, and lack of technical knowledge of inputs requirements are responsible for poor use of the inputs. Labour, fertilizer, seed and herbicides are all over utilized except insecticide which is underutilized. Among the problems encountered in groundnut production in the study are lacks of capital and extension services. These two problems accounted for over 78% of the problem of groundnut in the study area. It is therefore recommended that government and research institutes should strengthen extension services to deliver improved technologies to the farmers. Farmers are also advised to source for loans through cooperatives, banks and other available sources at low charges and the procedure for loan should be made simple to enable farmers’ access loans so that groundnut production can be improved.

Biodiversity effects in the wild are common and as strong as key drivers of productivity.

Science.gov (United States)

Duffy, J Emmett; Godwin, Casey M; Cardinale, Bradley J

2017-09-14

More than 500 controlled experiments have collectively suggested that biodiversity loss reduces ecosystem productivity and stability. Yet the importance of biodiversity in sustaining the world's ecosystems remains controversial, largely because of the lack of validation in nature, where strong abiotic forcing and complex interactions are assumed to swamp biodiversity effects. Here we test this assumption by analysing 133 estimates reported in 67 field studies that statistically separated the effects of biodiversity on biomass production from those of abiotic forcing. Contrary to the prevailing opinion of the previous two decades that biodiversity would have rare or weak effects in nature, we show that biomass production increases with species richness in a wide range of wild taxa and ecosystems. In fact, after controlling for environmental covariates, increases in biomass with biodiversity are stronger in nature than has previously been documented in experiments and comparable to or stronger than the effects of other well-known drivers of productivity, including climate and nutrient availability. These results are consistent with the collective experimental evidence that species richness increases community biomass production, and suggest that the role of biodiversity in maintaining productive ecosystems should figure prominently in global change science and policy.

Full Text Available Wild emmer wheat (Triticum turgidum ssp. dicoccoides is considered a promising source for improving stress resistances in domesticated wheat. Here we explored the potential of selected quantitative trait loci (QTLs from wild emmer wheat, introgressed via marker-assisted selection, to enhance drought resistance in elite durum (T. turgidum ssp. durum and bread (T. aestivum wheat cultivars. The resultant near-isogenic lines (BC3F3 and BC3F4 were genotyped using SNP array to confirm the introgressed genomic regions and evaluated in two consecutive years under well-watered (690–710 mm and water-limited (290–320 mm conditions. Three of the introgressed QTLs were successfully validated, two in the background of durum wheat cv. Uzan (on chromosomes 1BL and 2BS, and one in the background of bread wheat cvs. Bar Nir and Zahir (chromosome 7AS. In most cases, the QTL x environment interaction was validated in terms of improved grain yield and biomass - specifically under drought (7AS QTL in cv. Bar Nir background, under both treatments (2BS QTL, and a greater stability across treatments (1BL QTL. The results provide a first demonstration that introgression of wild emmer QTL alleles can enhance productivity and yield stability across environments in domesticated wheat, thereby enriching the modern gene pool with essential diversity for the improvement of drought resistance.

Contemporary programs in support of traditional ways: Inuit perspectives on community freezers as a mechanism to alleviate pressures of wild food access in Nain, Nunatsiavut.

Rapid socio-cultural, economic, and environmental changes are challenging wild food access and thus food security for Inuit in the Canadian Arctic. In response to the continued value and practice of harvesting wild foods, communities are establishing "wild food support" initiatives. This study evaluated how one such initiative, a community freezer, in Nain, Nunatsiavut supported wild food access for community members. Data were collected through: interviews and focus groups with users, freezer managers, and active harvesters; participant observation; and document analysis. Results indicated that the community freezer supported socio-cultural, economic and local access to wild foods. However, there were issues associated with supply, dependency, social exclusion, and tension between feasibility and traditional values and practices. Communities, governments, and policymakers are urged to consider social and physical location as factors when investing in and monitoring such initiatives. The Nunatsiavut Government and the Nain Inuit Community Government have since worked together to modify this early freezer initiative due, in part, to this study's findings.

Wild birds play a major role in the evolution, maintenance, and spread of avian influenza viruses. However, surveillance for these viruses in wild birds is sporadic, geographically biased, and often limited to the last outbreak virus. To identify opportunities to optimize wild bird surveillance for understanding viral diversity, we reviewed responses to a World Organisation for Animal Health–administered survey, government reports to this organization, articles on Web of Knowledge, and the Influenza Research Database. At least 119 countries conducted avian influenza virus surveillance in wild birds during 2008–2013, but coordination and standardization was lacking among surveillance efforts, and most focused on limited subsets of influenza viruses. Given high financial and public health burdens of recent avian influenza outbreaks, we call for sustained, cost-effective investments in locations with high avian influenza diversity in wild birds and efforts to promote standardized sampling, testing, and reporting methods, including full-genome sequencing and sharing of isolates with the scientific community.

A fish plasma model (FPM) has been proposed as a screening technique to prioritize potential hazardous pharmaceuticals to wild fish. However, this approach does not account for inter- or intraspecies variability of pharmacokinetic and pharmacodynamic parameters. The present study elucidated the uptake potency (from ambient water), tissue distribution, and biological risk of 20 pharmaceutical and personal care product (PPCP) residues in wild cyprinoid fish inhabiting treated-wastewater-impacted streams. In order to clarify the uncertainty of the FPM for PPCPs, we compared the plasma bioaccumulation factor in the field (BAFplasma = measured fish plasma/ambient water concentration ratio) with the predicted plasma bioconcentration factor (BCFplasma = fish plasma predicted by use of theoretical partition coefficients/ambient water concentration ratio) in the actual environment. As a result, the measured maximum BAFplasma of inflammatory agents was up to 17 times higher than theoretical BCFplasma values, leading to possible underestimation of toxicological risk on wild fish. When the tissue-blood partition coefficients (tissue/blood concentration ratios) of PPCPs were estimated, higher transportability into tissues, especially the brain, was found for psychotropic agents, but brain/plasma ratios widely varied among individual fish (up to 28-fold). In the present study, we provide a valuable data set on the intraspecies variability of PPCP pharmacokinetics, and our results emphasize the importance of determining PPCP concentrations in possible target organs as well as in the blood to assess the risk of PPCPs on wild fish.

Overexpression of wild-type aspartokinase increases L-lysine production in the thermotolerant methylotrophic bacterium Bacillus methanolicus.

Aspartokinase (AK) controls the carbon flow into the aspartate pathway for the biosynthesis of the amino acids l-methionine, l-threonine, l-isoleucine, and l-lysine. We report here the cloning of four genes (asd, encoding aspartate semialdehyde dehydrogenase; dapA, encoding dihydrodipicolinate synthase; dapG, encoding AKI; and yclM, encoding AKIII) of the aspartate pathway in Bacillus methanolicus MGA3. Together with the known AKII gene lysC, dapG and yclM form a set of three AK genes in this organism. Overexpression of dapG, lysC, and yclM increased l-lysine production in wild-type B. methanolicus strain MGA3 2-, 10-, and 60-fold (corresponding to 11 g/liter), respectively, without negatively affecting the specific growth rate. The production levels of l-methionine (less than 0.5 g/liter) and l-threonine (less than 0.1 g/liter) were low in all recombinant strains. The AK proteins were purified, and biochemical analyses demonstrated that they have similar V(max) values (between 47 and 58 micromol/min/mg protein) and K(m) values for l-aspartate (between 1.9 and 5.0 mM). AKI and AKII were allosterically inhibited by meso-diaminopimelate (50% inhibitory concentration [IC(50)], 0.1 mM) and by l-lysine (IC(50), 0.3 mM), respectively. AKIII was inhibited by l-threonine (IC(50), 4 mM) and by l-lysine (IC(50), 5 mM), and this enzyme was synergistically inhibited in the presence of both of these amino acids at low concentrations. The correlation between the impact on l-lysine production in vivo and the biochemical properties in vitro of the individual AK proteins is discussed. This is the first example of improving l-lysine production by metabolic engineering of B. methanolicus and also the first documentation of considerably increasing l-lysine production by overexpression of a wild-type AK.

Factors to consider in developing individual pharmaceutical product quality risk profiles useful to government procurement agencies.

Xu, Wei; Boehm, Garth; Zheng, Qiang

2016-01-01

Governments that procure pharmaceutical products from an Essential Medicine List (EML) bear special responsibility for the quality of these products. In this article we examine the possibility of developing a pharmaceutical product quality risk assessment scheme for use by government procurement officials. We use the Chinese EML as a basis, and US recall data is examined as it is publically available.This is justified as the article is only concerned with inherent product quality risks. After establishing a link between Chinese essential medicines and those available in the US, we examine US recall data to separate product specific recalls. We conclude that, in addition to existing manufacturing based risks, there are two other product specific risks that stand out from all others, degradation and dissolution failure. Methodology for relative product risk for degradation is needed to be developed and further work is required to better understand dissolution failures which largely occur with modified-release solid oral products. We conclude that a product specific quality risk profile would be enhanced by including a risk assessment for degradation for all products, and in the case of solid oral products, dissolution.

The antioxidant level of Alaska's wild berries: high, higher and highest

2013-08-01

Full Text Available Background . In the last few years, antioxidants have become the stars of the nutritional world. Antioxidants are important in terms of their ability to protect against oxidative cell damage that can lead to conditions, such as Alzheimer's disease, cancer and heart disease – conditions also linked with chronic inflammation. The antioxidant and anti-inflammatory effects of Alaska's wild berries may have the potential to help prevent these diseases. Objective . To discover the antioxidant levels of Alaska wild berries and the ways these antioxidant levels translate when preservation methods are applied to the berry. Design . This research centred on both the raw berries and products made from the berries. In the first year, a variety of wild berries were tested to discover their oxygen radical absorption capacity (ORAC in the raw berries. The second level of the research project processed 4 different berries – blueberries, lingonberries, salmonberries, highbush cranberries – into 8 or 9 products made from these berries. The products were tested for both ORAC as well as specific antioxidants. Results . The Alaska wild berries collected and tested in the first experiment ranged from 3 to 5 times higher in ORAC value than cultivated berries from the lower 48 states. For instance, cultivated blueberries have an ORAC scale of 30. Alaska wild dwarf blueberries measure 85. This is also higher than lower 48 wild blueberries, which had a score of 61. All of the Alaskan berries tested have a level of antioxidant considered nutritionally valuable, ranging from 19 for watermelon berries to 206 for lingonberries on the ORAC scale. With the processed products made from 4 Alaska wild berries, one of the unexpected outcomes of the research was that the berries continued to have levels of antioxidants considered high, despite the effects of commonly used heat-processing techniques. When berries were dehydrated, per gram ORAC values increased. Conclusion

A stated preference investigation into the Chinese demand for farmed vs. wild bear bile.

Full Text Available Farming of animals and plants has recently been considered not merely as a more efficient and plentiful supply of their products but also as a means of protecting wild populations from that trade.

Co-production, new public governance and third sector social services in Europe

Victor Pestoff

2011-01-01

political and economic challenges facing the welfare state in the 21st century. Co-production provides a model for the mix of public service agents and citizens who contribute to the provision of a public service. New Public Governance (NPG puts much greater emphasis on citizen participation and third sector provision of social services than either traditional public administration or New Public Management. Co-production is a core element of NPG that promotes the mix of public service agents and citizens who contribute to the provis ionof a public service. This paper explores the implications of two comparative studies of paren tparticipation in preschool services in Europe. They observe that citizen participation clearly varies between different providers of social services, as too does client and staff influence. This empirical overview concludes that some third sector providers can facilitate greater citizen participation, while a 'glass ceiling' for participation exists in municipal and for-profit preschool services. These findings can contribute to a better understanding of the emerging paradigm of New Public Governance.

Viral pathogen production in a wild grass host driven by host growth and soil nitrogen.

Whitaker, Briana K; Rúa, Megan A; Mitchell, Charles E

Nutrient limitation is a basic ecological constraint that has received little attention in studies on virus production and disease dynamics. Nutrient availability could directly limit the production of viral nucleic acids and proteins, or alternatively limit host growth and thus indirectly limit metabolic pathways necessary for viral replication. In order to compare direct and indirect effects of nutrient limitation on virus production within hosts, we manipulated soil nitrogen (N) and phosphorus (P) availability in a glasshouse for the wild grass host Bromus hordeaceus and the viral pathogen Barley yellow dwarf virus-PAV. We found that soil N additions increased viral concentrations within host tissues, and the effect was mediated by host growth. Specifically, in statistical models evaluating the roles of host biomass production, leaf N and leaf P, viral production depended most strongly on host biomass, rather than the concentration of either nutrient. Furthermore, at low soil N, larger plants supported greater viral concentrations than smaller ones, whereas at high N, smaller plants supported greater viral concentrations. Our results suggest that enhanced viral productivity under N enrichment is an indirect consequence of nutrient stimulation to host growth rate. Heightened pathogen production in plants has important implications for a world facing increasing rates of nutrient deposition. © 2015 The Authors. New Phytologist © 2015 New Phytologist Trust.

The African wild dog (Lycaon pictus) is an endangered exotic canid with less than 5500 animals remaining in the wild. Despite numerous strategies to conserve this species, numbers of free-living animals are in decline. It is a highly social species with a complex pack structure: separate male and female dominant hierarchies with, typically, participation of subdominant adults in the rearing of the dominant breeding pairs' pups. Basic reproductive knowledge is largely missing in this species, with only limited information available on the profile of reproductive hormones, based on non-invasive endocrine monitoring. The dominant or alpha male and female are reproductively active and the subdominants are generally reproductively suppressed. However, the occasional production of litters by subdominant females and evidence of multiple paternity within litters suggests that fertility of subordinates is not completely inhibited. In this respect, there are still considerable gaps in our knowledge about the mechanisms governing reproduction and reproductive suppression in African wild dogs, particularly the influence of dominance and pack structure on both male and female fertility. Given concerns over the long-term survival of this species, further research in this area is essential to provide valuable information for their captive breeding and conservation. Reproductive information can also be applied to the development of Assisted Reproductive Techniques for this species; the utility of which in African wild dog conservation is also discussed.

Full Text Available Two conceptual frameworks have been analytically dominant in researching innovation dynamics in sustainability transition processes, namely technological innovation systems (TIS and the multi-level perspective (MLP. The innovation systems has been principally concerned with emerging new technologies and their potential contribution to future sustainability, whereas MLP has been more strongly oriented toward reconstructing historical processes of sectorial change. In this perspective, this study aims to analyses how global climate change and environmental pressures impact on the governance of supply chain and the ripple effects on natural resource-intensive economies. Some initiatives are taken to address regulatory issues and reconcile decision-making tools on quality assurance program on value chains. This includes a multi-level perspective (MLP as Carbon Disclosure Project (CDP and technological innovation systems (TIS as Geographic Information System (GIS used as a tracking system for monitoring sustainable practices. The paper discuss the drivers of sustainable beef production system, mainly in Legal Amazon, Brazil, and requirements from a largest retailer aligned to Brazilian public policies. This study presents three distinct strategies: (1 government and public policies to control deforestation related to beef cattle production system, (2 economic approach related to transnational supermarket chain and sustainability initiatives, (3 collective action for decision-making by multiple drivers

Discovery of an inhibitor of the production of the Pseudomonas aeruginosa virulence factor pyocyanin in wild-type cells

Directory of Open Access Journals (Sweden)

Bernardas Morkunas

2016-07-01

Full Text Available Pyocyanin is a small molecule produced by Pseudomonas aeruginosa that plays a crucial role in the pathogenesis of infections by this notorious opportunistic pathogen. The inhibition of pyocyanin production has been identified as an attractive antivirulence strategy for the treatment of P. aeruginosa infections. Herein, we report the discovery of an inhibitor of pyocyanin production in cultures of wild-type P. aeruginosa which is based around a 4-alkylquinolin-2(1H-one scaffold. To the best of our knowledge, this is the first reported example of pyocyanin inhibition by a compound based around this molecular framework. The compound may therefore be representative of a new structural sub-class of pyocyanin inhibitors, which could potentially be exploited in in a therapeutic context for the development of critically needed new antipseudomonal agents. In this context, the use of wild-type cells in this study is notable, since the data obtained are of direct relevance to native situations. The compound could also be of value in better elucidating the role of pyocyanin in P. aeruginosa infections. Evidence suggests that the active compound reduces the level of pyocyanin production by inhibiting the cell–cell signalling mechanism known as quorum sensing. This could have interesting implications; quorum sensing regulates a range of additional elements associated with the pathogenicity of P. aeruginosa and there is a wide range of other potential applications where the inhibition of quorum sensing is desirable.

Many cultivated plant species are able to hybridize with related wild plants. However, it is not clear whether their hybrids are able to survive and reproduce outside managed fields, and if cultivar genes introgress into wild populations. In areas where wild carrots co-occur with carrot root......-crops, pollen and seeds may flow from two different sources in the fields to the surrounding wild populations: from pure cultivar plants that occasionally flower, and from flowering 'bolters' that originate from hybridizations between wild (male) and cultivated carrots (female) in seed production fields...... by AFLP. Four hybrids were identified among the 71 plants analysed, and these were most likely F(2) or backcross individuals, sired by pollen from hybrid bolters.

Global trends in pollinator-dependent crops have raised awareness of the need to support managed and wild bee populations to ensure sustainable crop production. Provision of sufficient forage resources is a key element for promoting bee populations within human impacted landscapes, particularly those in agricultural lands where demand for pollination service is high and land use and management practices have reduced available flowering resources. Recent government incentives in North America and Europe support the planting of wildflowers to benefit pollinators; surprisingly, in North America there has been almost no rigorous testing of the performance of wildflower mixes, or their ability to support wild bee abundance and diversity. We tested different wildflower mixes in a spatially replicated, multiyear study in three regions of North America where production of pollinator-dependent crops is high: Florida, Michigan, and California. In each region, we quantified flowering among wildflower mixes composed of annual and perennial species, and with high and low relative diversity. We measured the abundance and species richness of wild bees, honey bees, and syrphid flies at each mix over two seasons. In each region, some but not all wildflower mixes provided significantly greater floral display area than unmanaged weedy control plots. Mixes also attracted greater abundance and richness of wild bees, although the identity of best mixes varied among regions. By partitioning floral display size from mix identity we show the importance of display size for attracting abundant and diverse wild bees. Season-long monitoring also revealed that designing mixes to provide continuous bloom throughout the growing season is critical to supporting the greatest pollinator species richness. Contrary to expectation, perennials bloomed in their first season, and complementarity in attraction of pollinators among annuals and perennials suggests that inclusion of functionally diverse

Do managed bees drive parasite spread and emergence in wild bees?

Science.gov (United States)

Graystock, Peter; Blane, Edward J; McFrederick, Quinn S; Goulson, Dave; Hughes, William O H

2016-04-01

Bees have been managed and utilised for honey production for centuries and, more recently, pollination services. Since the mid 20th Century, the use and production of managed bees has intensified with hundreds of thousands of hives being moved across countries and around the globe on an annual basis. However, the introduction of unnaturally high densities of bees to areas could have adverse effects. Importation and deployment of managed honey bee and bumblebees may be responsible for parasite introductions or a change in the dynamics of native parasites that ultimately increases disease prevalence in wild bees. Here we review the domestication and deployment of managed bees and explain the evidence for the role of managed bees in causing adverse effects on the health of wild bees. Correlations with the use of managed bees and decreases in wild bee health from territories across the globe are discussed along with suggestions to mitigate further health reductions in wild bees.

Wild Maid, Wild Soul, A Wild Wild Weed: Niki de Saint Phalle’s Fierce Femininities, c. 1960-66

Directory of Open Access Journals (Sweden)

Amelia Jones

2015-11-01

Full Text Available Self-described as “wild maid,” “wild soul,” “a wild wild weed,” Niki de Saint Phalle narrated herself as artistic subject in a concerted way that stands out in the history of art: as both creatively driven and emotionally renegade and excessive, as both definitively woman and definitively artist. In this essay I take this special case of self-narration, and the particular power of St. Phalle’s work, as an opportunity to explore the relationship between.(auto-biography and artistic practice. The case of St. Phalle, a radical sculptor, performance artist, writer, and filmmaker, allows us to understand the exaggerated way in which women artists were until very recently forced to adopt “fierce femininities” to make a place for themselves as artists. In this way, I suggest that St. Phalle represents a key inspirational force opening the door for second wave feminism and the feminist art movement.

By contrast, few studies have examined toxicity of pesticides on wild bees, let alone effects of...

THE LOCAL PRODUCTIVE ARRANGEMENTS IN THE OURINHOS GOVERNMENT REGION - SÃO PAULO - BRAZIL: SOCIO-PRODUCTIVE DYNAMIC AND TERRITORIAL DEVELOPMENT

Full Text Available This article seeks to develop an analysis of the territorial evidences of discussion on local productive arrangements, those clusters, using as spatial scale of the regional analysis, more precisely the Ourinhos Government Region. Form of industrial organization emerging in the 1990s, the APLs express localized concentrations of specialized companies in the same industry and establishing partnerships among themselves and with other institutions, with varying impacts on the development and governance of cities. Far from exhausting this debate, we consider the model of APL as an alternative strategy for the development of territories and their small businesses, despite their financial and institutional weaknesses. Also, put hypothesized that there are potential clusters and agglomerations in the Ourinhos region that are still unknown and did not receive institutional and financial contribution of the state, staying on the sidelines of the economic benefits of local development, for which they are poorly organized or disorganized. Tracing the framework of national and local policies to arrangements and productive agglomerations, accentuates the way of development in clusters like that guided resources, institutions and local networks, dependent, however, the larger scales of government action. That said, we propose a methodology of analysis grounded in documentary and statistical data research (IBGE and RAIS seeking to achieve the objectives of identifying the major industrial clusters in the region studied, recognizing its dynamism to local economies and relevance or not to consider some regional industrial agglomerations as APLs.

The majority of the consumer sample reported no perceived differences between farmed versus wild fish. However, mean perception scores were slightly in favour of wild fish......The increasing number of marketable fish being supplied from aquaculture is a response to the increasing demand for healthy food and is filling the gap left by depleting natural fish stocks. Little is known about the awareness and perception of the consumer in terms of farmed fish versus fish from...... capture fisheries. The consumer's subjective point of view is of overriding importance for the production system and product acceptance as well as for future market success.

Wild apricot (Prunus armeniaca L.) commonly known as chulli is a potential fruit widely distributed in North-West Himalayan regions of the world. The fruits are good source of carbohydrates, vitamins, minerals besides having attractive colour and typical flavour. Unlike table purpose varieties of apricots like New Castle, the fruits of wild apricot are unsuitable for fresh consumption because of its high acid and low sugar content. However, the fruits are traditionally utilized for open sun drying, pulping to prepare different products such as jams, chutney and naturally fermented and distilled liquor. But, scientific literature on processing and value addition of wild apricot is scanty. Preparation of jam with 25 % wild apricot +75 % apple showed maximum score for organoleptic characteristics due to better taste and colour. Osmotic dehydration has been found as a suitable method for drying of wild type acidic apricots. A good quality sauce using wild apricot pulp and tomato pulp in the ratio of 1:1 has been prepared, while chutney of good acceptability prepared from wild apricot pulp (100 %) has also been documented. Preparation of apricot-soy protein enriched products like apricot-soya leather, toffee and fruit bars has been reported, which are reported to meet the protein requirements of adult and children as per the recommendations of ICMR. Besides these processed products, preparation of alcoholic beverages like wine, vermouth and brandy from wild apricot fruits has also been reported by various researchers. Further, after utilization of pulp for preparation of value added products, the stones left over have been successfully utilized for oil extraction which has medicinal and cosmetic value. The traditional method of oil extraction has been reported to be unhygienic and result in low oil yield with poor quality, whereas improved mechanical method of oil extraction has been found to produce good quality oil. The apricot kernel oil and press cake have

Rates of trichinellosis have declined significantly in the United States due to improved pork production practices and public awareness of the danger of eating raw or undercooked pork. In April 2011, the Minnesota Department of Health received a report of presumptive trichinellosis in a 50-year-old man with a history of wild boar consumption. A public health investigation was initiated. Medical record reviews and patient and family interviews were conducted. Trichinella species serology was performed on patient and family serum samples, and larval identification was attempted on clinical specimens and meat samples. The index patient harvested a wild boar from an Iowa game farm; he processed the meat after returning home and developed gastrointestinal symptoms 2 days later. Four days after his illness onset, all 5 family members consumed a roast from the boar. The index patient sought healthcare 4 times after illness onset before being definitively diagnosed with trichinellosis. Following initiation of albendazole therapy, the index patient developed atrial fibrillation. One additional family member who processed the raw meat was diagnosed with trichinellosis. Trichinella spiralis larvae were identified in wild boar meat samples. Trichinellosis has long been recognized as a potential hazard of consuming undercooked wild carnivore meat, and historically has been associated with consumption of pork from domestic swine, but may be unfamiliar to practicing clinicians in the United States. Education of hunters and the broader population on the potential for trichinellosis and the importance of proper handling and cooking meat from wild or free-range animals needs to be reinforced.

Wild bees enhance honey bees’ pollination of hybrid sunflower

Greenleaf, Sarah S.; Kremen, Claire

2006-01-01

Pollinators are required for producing 15–30% of the human food supply, and farmers rely on managed honey bees throughout the world to provide these services. Yet honey bees are not always the most efficient pollinators of all crops and are declining in various parts of the world. Crop pollination shortages are becoming increasingly common. We found that behavioral interactions between wild and honey bees increase the pollination efficiency of honey bees on hybrid sunflower up to 5-fold, effectively doubling honey bee pollination services on the average field. These indirect contributions caused by interspecific interactions between wild and honey bees were more than five times more important than the contributions wild bees make to sunflower pollination directly. Both proximity to natural habitat and crop planting practices were significantly correlated with pollination services provided directly and indirectly by wild bees. Our results suggest that conserving wild habitat at the landscape scale and altering selected farm management techniques could increase hybrid sunflower production. These findings also demonstrate the economic importance of interspecific interactions for ecosystem services and suggest that protecting wild bee populations can help buffer the human food supply from honey bee shortages.

How do HIV and AIDS impact the use of natural resources by poor rural populations? The case of wild animal products

Directory of Open Access Journals (Sweden)

Charles M. Shackleton

2012-01-01

Full Text Available As a result of heightened financial and food insecurity, populations adversely affected by HIV and/or AIDS may be more likely to utilise wild natural resources to supplement their diet and livelihoods. Should this effect be pronounced, HIV and AIDS may pose a serious environmental threat. We explored the hypothesis that the presence of factors in the household, such as chronic illness in and recent mortality of individuals in a high HIV-risk age group, as well as the fostering of orphans, are associated with increased utilisation of wild animal products (WAPs at the household level. We randomly surveyed 519 households from four sites in rural South Africa, recording household socio-economic status, the utilisation of wild animal products and health and demographic factors attributed to HIV or AIDS. Binary logistic regressions were used to test if households with markers of HIV and/or AIDS affliction were more likely to have a higher incidence and frequency of WAP utilisation relative to non-afflicted households, after adjusting for socio-economic and demographic variables. We found that, although households with markers of HIV and/or AIDS were generally poorer and had higher dependency ratios, there was no evidence to support the hypothesis that WAP harvesting was associated with either poverty, or markers of HIV and/or AIDS affliction. Our findings suggest that generalisations about a possible interaction between HIV and/or AIDS and the environment may not uniformly apply to all categories of natural resources or to all user groups.

Differences in ultrasonic vocalizations between wild and laboratory California mice (Peromyscus californicus.

Directory of Open Access Journals (Sweden)

Matina C Kalcounis-Rueppell

Full Text Available BACKGROUND: Ultrasonic vocalizations (USVs emitted by muroid rodents, including laboratory mice and rats, are used as phenotypic markers in behavioral assays and biomedical research. Interpretation of these USVs depends on understanding the significance of USV production by rodents in the wild. However, there has never been a study of muroid rodent ultrasound function in the wild and comparisons of USVs produced by wild and laboratory rodents are lacking to date. Here, we report the first comparison of wild and captive rodent USVs recorded from the same species, Peromyscus californicus. METHODOLOGY AND PRINCIPAL FINDINGS: We used standard ultrasound recording techniques to measure USVs from California mice in the laboratory (Peromyscus Genetic Stock Center, SC, USA and the wild (Hastings Natural History Reserve, CA, USA. To determine which California mouse in the wild was vocalizing, we used a remote sensing method that used a 12-microphone acoustic localization array coupled with automated radio telemetry of all resident Peromyscus californicus in the area of the acoustic localization array. California mice in the laboratory and the wild produced the same types of USV motifs. However, wild California mice produced USVs that were 2-8 kHz higher in median frequency and significantly more variable in frequency than laboratory California mice. SIGNIFICANCE: The similarity in overall form of USVs from wild and laboratory California mice demonstrates that production of USVs by captive Peromyscus is not an artifact of captivity. Our study validates the widespread use of USVs in laboratory rodents as behavioral indicators but highlights that particular characteristics of laboratory USVs may not reflect natural conditions.

2011-01-01

This paper aimed to study the genetic variability within different types of Cynara cardunculus L., domestic and wild types, for their grain oil amount and oil fatty acid composition. The grain oils were extracted from 8 domestic cardoons and 4 wild cardoons, by Soxhlet method, and obtained oils were characterized for palmitic, stearic, oleic and linoleic acids by gas chromatography. The oil amount, resulted on average of accessions 216 g kg -1 DM with a good range of variability (CV = 11.7%). Unsaturated acids (oleic and linoleic) predominated over saturated ones (stearic and palmitic acids), the chemical characterization of extracted oil, showed the main compound (as % of analysed fatty acids), averaged for all populations, was linoleic acid (44.5%), followed by oleic acid (42.6%), palmitic acid (9.8%) and stearic acid (3.1%). In particular referring the oleic acid wild cardoon populations showed a mean value of 289 g kg -1 oil, against a mean value of 472 g kg -1 oil showed by domestic cardoon accessions. Three of the studied domestic cardoon ('DC1', 'DC3' and 'DC7') showed values higher than 795 g kg -1 oil, while all the other accessions had concentration lower than 370 g kg -1 oil. The three types of domestic cardoon 'DC1', 'DC3' and 'DC7' showed a fatty acids profile similar to genetic modified sunflower oil, representing new genetic material that potentially could be used for high quality biodiesel production, characterised by a low Iodine Number. -- Highlights: → The grain oils from 12 cardoons were characterized for fatty acids composition. → The oil amount, resulted on average of accessions 216 g kg -1 DM. → Oleic and linoleic acids predominated over stearic and palmitic acids. → Three domestic cardoons grain oil showed high oleic acid content (795 g kg -1 oil). → This oil could be used for high quality biodiesel production, with a low IN.

Bovine tuberculosis (bTB) is a zoonosis caused mainly by Mycobacterium bovis that affects domestic and wild animals. In Brazil, there are no epidemiological studies on tuberculosis in wild animal populations and their possible role in the disease maintenance in cattle herds; thus, the aim of this study was to evaluate the occurrence of tuberculosis in wild boars in Rio Grande do Sul, southern Brazil. Tissue samples of animals hunted under government consent were submitted to histopathology and M. bovis polymerase chain reaction (PCR) as screening tests; the positive samples were subsequently submitted to bacterial isolation, the gold standard diagnosis. Eighty animals were evaluated, of which 27.9% and 31.3% showed histopathological changes and M. bovis genome presence, respectively. Moreover, 23.8% of the animals had at least one organ with isolates classified as Mycobacterium tuberculosis complex (MTC). Three hunting points were risk factors for positive results on screening tests. This study shows the occurrence of tuberculosis in a wild boars' population, and raise the possibility of these animals to play a role as disease reservoirs in southern Brazil. These results may help to improve the Brazilian tuberculosis control programme, as well as elucidate the circulation of mycobacteria in this country. © 2017 Blackwell Verlag GmbH.

Divergence in wine characteristics produced by wild and domesticated strains of Saccharomyces cerevisiae

Hyma, Katie E; Saerens, Sofie M; Verstrepen, Kevin J; Fay, Justin C

2011-01-01

The budding yeast Saccharomyces cerevisiae is the primary species used by wine makers to convert sugar into alcohol during wine fermentation. Saccharomyces cerevisiae is found in vineyards, but is also found in association with oak trees and other natural sources. Although wild strains of S. cerevisiae as well as other Saccharomyces species are also capable of wine fermentation, a genetically distinct group of S. cerevisiae strains is primarily used to produce wine, consistent with the idea that wine making strains have been domesticated for wine production. In this study, we demonstrate that humans can distinguish between wines produced using wine strains and wild strains of S. cerevisiae as well as its sibling species, Saccharomyces paradoxus. Wine strains produced wine with fruity and floral characteristics, whereas wild strains produced wine with earthy and sulfurous characteristics. The differences that we observe between wine and wild strains provides further evidence that wine strains have evolved phenotypes that are distinct from their wild ancestors and relevant to their use in wine production.

2006-03-01

The biogeography of pungency in three species of wild chili in the chaco and surrounding highland habitats of southeastern Bolivia is described. We report that Capsicum chacoense, C. baccatum, and C. eximium are polymorphic for production of capsaicin and its analogs, such that completely pungent and completely nonpungent individuals co-occur in some populations. In C. chacoense, the density of plants and the proportion of pungent plants increased with elevation. Above 900 m, all individuals in all populations except two were pungent; nonpungent individuals in at least one of the two polymorphic populations were likely a result of spreading by humans. The occurrence of pungent and nonpungent individuals in three species of ancestral Capsicum and the geographic variation of pungency within species suggest that production of capsaicin and its analogs entails both costs and benefits, which shift from one locality to another. Determining the selection pressures behind such shifts is necessary to understand the evolution of pungency in chilies.

Gross Domestic Product (GDP) is an indicator of economic growth in a region. GDP is a panel data, which consists of cross-section and time series data. Meanwhile, panel regression is a tool which can be utilised to analyse panel data. There are three models in panel regression, namely Common Effect Model (CEM), Fixed Effect Model (FEM) and Random Effect Model (REM). The models will be chosen based on results of Chow Test, Hausman Test and Lagrange Multiplier Test. This research analyses palm oil about production, export, and government consumption to five district GDP are in West Kalimantan, namely Sanggau, Sintang, Sambas, Ketapang and Bengkayang by panel regression. Based on the results of analyses, it concluded that REM, which adjusted-determination-coefficient is 0,823, is the best model in this case. Also, according to the result, only Export and Government Consumption that influence GDP of the districts.

The present study describes the screening of different agroindustrial byproducts for enhanced production of alkaline protease by a wild and EMS induced mutant strain of Bacillus subtilis IH-72EMS8. During submerged fermentation, different agro-industrial byproducts were tested which include defatted seed meals of rape, guar, sunflower, gluten, cotton, soybean, and gram. In addition to these meals, rice bran, wheat bran, and wheat flour were also evaluated for protease production. Of all the byproducts tested, soybean meal at a concentration of 20 g/L gave maximum production of the enzyme, that is, 5.74  ±  0.26 U/mL from wild and 11.28  ±  0.45 U/mL from mutant strain, during submerged fermentation. Different mesh sizes (coarse, medium, and fine) of the soybean meal were also evaluated, and a finely ground soybean meal (fine mesh) was found to be the best. In addition to the defatted seed meals, their alkali extracts were also tested for the production of alkaline protease by Bacillus subtilis, but these were proved nonsignificant for enhanced production of the enzyme. The production of the enzyme was also studied in solid state fermentation, and different agro-industrial byproducts were also evaluated for enzyme production. Wheat bran partially replaced with guar meal was found as the best substrate for maximum enzyme production under solid state fermentation conditions. PMID:24294129

Full Text Available Classical swine fever (CSF is a viral disease with severe economic consequences for domestic pigs. Natural hosts for the CSF virus (CSFV are members of the family Suidae, i.e. Eurasian wild boar (sus scrofa are also susceptible. CSF in wild boar poses a serious threat to domestic pigs. CSFV is an enveloped RNA virus belonging to the pestivirus genus of the Flaviviridae family. Transmission of the infection is usually by direct contact or by feeding of contaminated meat products. In recent decades CSF has been successfully eradicated from Australia, North America, and the European Union. In areas with dense wild boar populations CSF tends to become endemic whereas it is often self-limiting in small, less dense populations. In recent decades eradication strategies of CSF in wild boar have been improved considerably. The reduction of the number of susceptible animals to a threshold level where the basic reproductive number is R0<1 is the major goal of all control efforts. Depending on the epidemiological situation, hunting measures combined with strict hygiene may be effective in areas with a relatively low density of wild boar. Oral immunization was shown to be highly effective in endemic situations in areas with a high density of wild boar.

Paradis, C.

2010-01-01

Recent supply disruptions have highlighted the fragility of the supply chain that delivers essential medical isotopes to patients globally. A new and more reliable way of supplying isotopes to Canadians needs to be found. That is why the Government of Canada established the Expert Review Panel on Medical Isotope Production (the Panel) in June 2009. The Government recognizes the relatively long lead times associated with the development of any new source of medical. isotopes. To ensure that appropriate action is taken now for the long term, the Government tasked the Panel with reporting to the Minister. of Natural Resources on its assessment of the most viable options for securing supplies of technetium-99m (Tc99r) for the Canadian health care system over the medium and long term and the actions that may be required by governments and others to facilitate realization of these options. The Panel reported to the Minister of Natural Resources on November 30, 2009. Since then, the Government has been carefully considering the recommendations of the Panel within the context of the broader nuclear and health care landscape. What follows is the Government's response to the Panel's thoughtful, comprehensive and insightful report, including actions that are planned based on its recommendations. (author)

Edible wild plant use in the Faroe Islands and Iceland

Ingvar Svanberg

2012-11-01

Full Text Available This paper reviews the use of wild edible plants in the Faroe Islands and Iceland from the times of the first settlement of Norse people in the Viking age until today, with a special emphasis on the 18th, 19th and 20th centuries. Animal products have been an important source of nutrients for the islanders of northern Atlantic. Cultivation of cereals on the other hand has played a minor role, and had already been abandoned by late medieval times in Iceland and by the early 20th century on the Faroes. Crops such as potatoes, turnips and other roots were only grown in the small patches of cultivated soil. Wild plants have therefore been of some importance for the Faroese people and the Icelanders; in the last centuries especially for the rural poor and during times of recessions. The native Angelica archangelica L. was gathered in the wild and also cultivated in gardens for centuries. A few species have been part of the regular food staple. Some plants are still gathered and made into food products by small companies, especially in Iceland. In the Faroes, the economic aspect of edible wild plant taxa is mostly of historical interest, although a few products of A. archangelica are sometimes available. Two taxa have been exploited as regular food exclusively in Iceland: Cetraria islandica (L. Arch. and Elymus arenarius L. Icelanders have used C. islandica from the early settlement days and continue to do so today, E. arenarius became obsolete as a food plant a century ago.

Without a doubt, fruits and vegetables are important components of a balanced and healthy diet. However, their consumption is very low in the world, with the lowest figures being reported in sub-Saharan Africa. The low consumption of fruits and vegetables means unbalanced and unhealthy diets, which has been linked to various diseases and conditions associated with increased mortality rates in worst cases. Poverty is the major contributor to the low consumption of fruits and vegetables in the majority of cases. However, the world, including sub-Saharan Africa, is endowed with numerous wild fruit and vegetable species which can be exploited and incorporated into the diets and help solve some nutrition related concerns. Therefore, in this review, we explore literature on wild fruits and vegetables with a special emphasis on some of the poorest regions of the world and where the lowest consumption figures are reported; their nutritional compositions; the status of their consumption and their role in the diet with a view to uncover their possible role in delivering a healthy and balanced diet as well as helping lower food and nutrition insecurity. A total of 396 articles were downloaded and analysed but only 213 were considered for this review. The results of the search indicate that wild fruits and vegetables are nutritionally rich and high in phytochemicals, especially antioxidants and therefore can possibly play a significant and positive role in delivering a healthy and balanced diet. However, the major challenge is the acceptability, accessibility as well as a lack of interest in wild fruits and vegetables and sheer neglect. People need to be educated using various forms of media on the nutritional and health benefits of these wild food plants with a view to bring them from the forest to the plate. Researchers need to channel more efforts towards domesticating them for ease of access, among other reasons. Governments need to incentivise the subsistence or

2014-03-01

Full Text Available The aim of this research is to characterise the wild rabbit (Oryctolagus cuniculus commercial game farms in Spain using variables related to structure, management and marketing. To this end, a structured survey was administered in 2009 to 21 privately-owned farms. This subsector was an average age of 13. The average size of the breeding stock of the farms was 431 does and 64 bucks. Eighty-five percent of the farms kept all or part of the breeding stock in cages and 38.1% used artificial insemination. All the farms carried out breeder self-replacement, 4.8% by buying wild rabbits from other farms, whereas 38.1% captured wild rabbits for this purpose. Nineteen percent of the wild rabbit game farms also produced other game species, mainly red-legged partridge (Alectoris rufa, pheasant (Phasianus colchicus and quail (Coturnix coturnix. Fourteen percent of the farms supplied wild rabbits to be used as prey to be released in programmes for the conservation of endangered predators, and 38.1% supplied breeding rabbits to be used by other farms to replace culled animals. Eighty-six percent of the farms offered the service of transporting the animals from the farm to the hunting grounds to their clients, and 14.3% advised customers on how to successfully release and restock hunting grounds. Seventy-six percent of the farms marketed their products throughout Spain, and 38.1% exported wild rabbits to neighbouring countries, mainly Portugal and France. Forty-three percent of the farms advertised themselves in hunting magazines, 19.1% promoted themselves by attending livestock and game fairs, and 38.1% had their own websites. In conclusion, this alternative rabbit production system constitutes a well-established subsector in Spain, despite being only 2 decades old. It also seems that it has not yet reached its development maturity. It shows wide diversity in terms of farm size and structure, as well as marketing and promotional activities.

Glucocorticoids circulating in breeding birds during egg production accumulate within eggs, and may provide a potent form of maternal effect on offspring phenotype. However, whether these steroids affect offspring development remains unclear. Here, we employed a non-invasive technique that experimentally elevated the maternal transfer of corticosterone to eggs in a wild population of house wrens. Feeding corticosterone-injected mealworms to free-living females prior to and during egg production increased the number of eggs that females produced and increased corticosterone concentrations in egg yolks. This treatment also resulted in an increase in the amount of yolk allocated to eggs. Offspring hatching from these eggs begged for food at a higher rate than control offspring and eventually attained increased prefledging body condition, a trait predictive of their probability of recruitment as breeding adults in the study population. Our results indicate that an increase in maternal glucocorticoids within the physiological range can enhance maternal investment and offspring development. Copyright © 2016 Elsevier Inc.

Arcelin, the antimetabolic protein from wild pulses is a known natural insecticidal molecule. Wild pulses with high arcelin content could serve as potential source to. increase the levels of insect resistance in cultivated pulse crops. In this study, arcelin (Arl) gene expression was screened in seven stored product insect pest resistant wild pulse varieties using real time RT-qPCR. Arcelin gene specific real time PCR primers were synthesized from arcelin mRNA sequence of the wild pulse variety, Lablab purpureus. The results revealed different levels of arcelin gene expression in the tested varieties. Canavalia virosa registered significantly high content indicating its suitability for utilization of arcelin gene in developing stored product insect pest resistance with other cultivated pulses.

Sheep’s milk has a high content of total solids, which qualifies it as a very good raw material for the production of fermented milk drinks. Currently, there are commercially produced kefirs and yogurts from sheep’s milk in the countries of the Mediterranean region. The growing interest in the consumption of these products is justified not only by their taste merits, but also because of their health-promoting proper- ties. The aim of the present study was to determine the effect of the addition of 1% of lyophilized wild garlic powder on the properties of kefirs from sheep’s milk. Sheep’s milk was pasteurized (85°C, 30 min), cooled down, enriched with 1% of freeze-dried wild garlic powder, inoculated with a Commercial VITAL kefir culture and fermented for 16 hours (26°C). The influence of wild garlic on acidity (pH, °SH), syneresis (%), texture (TPA test), colour (L*a*b*) and the sensory profile of kefirs was conducted. Wild garlic could be used as a taste and flavour modifier in the production of kefir from sheep’s milk. The addition of 1% of freeze-dried wild garlic slowed down the fermentation of kefir, changed colour and reduced syneresis. Wild garlic could be used as a valuable supplement and a modifier of taste and flavour in kefir from sheep’s milk.

2017-01-01

Nonnative Brook Trout Salvelinus fontinalis were introduced throughout western North America in the early 1900s, resulting in widespread self-sustaining populations that are difficult to eradicate and often threaten native salmonid populations. A novel approach for their eradication involves use of YY male (MYY) Brook Trout (created in the hatchery by feminizing XY males and crossing them with normal XY males). If MYY Brook Trout survive after stocking, and reproduce successfully with wild females, in theory this could eventually drive the sex ratio of the wild population to 100% males, at which point the population would not be able to reproduce and would be eradicated. This study represents the first successful development of a FYY and MYY salmonid broodstock, which was produced in four years at relatively low cost. Field trials demonstrated that stocked hatchery MYY Brook Trout survived and produced viable MYY offspring in streams, although reproductive fitness appeared to have been lower than their wild conspecifics. Even if reduced fitness is the norm in both streams and alpine lakes, our population simulations suggest that eradication can be achieved in reasonable time periods under some MYY stocking scenarios, especially when wild Brook Trout are simultaneously suppressed in the population.

To cope, both with the increasing demand for sugar and to win the global competition as well, government-owned sugar cane limited number xxi-xxii, has decided to enhance its productivity, among other things, by implementing ergonomics principles within their factories. In the execution, ergonomics application have been carried out since 1992, which resulted in safer, healthier, and more efficient working conditions and environment. Some of the improvements yielded economic gains through higher productivity via increased output, lower cost, faster processing, etc. Improvements related to cane transloading and unloading processes resulted in a higher amount of cane being transferred from the trucks to the lorries as well as from the lorries to the cane table. Fewer clinical visits, lower health care costs, more efficient inspection, and fewer fatigue complaints are also achieved by improvement steps, which increase the productivity as end results. With all those economic gains, full and long lasting management's concern and commitment could be created without a doubt.

Wild genius - domestic fool? Spatial learning abilities of wild and domestic guinea pigs

2010-03-01

Full Text Available Abstract Background Domestic animals and their wild relatives differ in a wide variety of aspects. The process of domestication of the domestic guinea pig (Cavia aperea f. porcellus, starting at least 4500 years ago, led to changes in the anatomy, physiology, and behaviour compared with their wild relative, the wild cavy, Cavia aperea. Although domestic guinea pigs are widely used as a laboratory animal, learning and memory capabilities are often disregarded as being very scarce. Even less is known about learning and memory of wild cavies. In this regard, one striking domestic trait is a reduction in relative brain size, which in the domesticated form of the guinea pig amounts to 13%. However, the common belief, that such a reduction of brain size in the course of domestication of different species is accomplished by less learning capabilities is not at all very well established in the literature. Indeed, domestic animals might also even outperform their wild conspecifics taking advantage of their adaptation to a man-made environment. In our study we compared the spatial learning abilities of wild and domestic guinea pigs. We expected that the two forms are different regarding their learning performance possibly related to the process of domestication. Therefore wild cavies as well as domestic guinea pigs of both sexes, aged 35 to 45 days, were tested in the Morris water maze to investigate their ability of spatial learning. Results Both, wild cavies and domestic guinea pigs were able to learn the task, proving the water maze to be a suitable test also for wild cavies. Regarding the speed of learning, male as well as female domestic guinea pigs outperformed their wild conspecifics significantly. Interestingly, only domestic guinea pigs showed a significant spatial association of the platform position, while other effective search strategies were used by wild cavies.

Therefore wild cavies as well as domestic guinea pigs of both sexes, aged 35 to 45 days, were tested in the Morris water maze to investigate their ability of spatial learning. Both, wild cavies and domestic guinea pigs were able to learn the task, proving the water maze to be a suitable test also for wild cavies. Regarding the speed of learning, male as well as female domestic guinea pigs outperformed their wild conspecifics significantly. Interestingly, only domestic guinea pigs showed a significant spatial association of the platform position, while other effective search strategies were used by wild cavies. The results demonstrate that domestic guinea pigs do not at all perform worse than their wild relatives in tests of spatial

Measuring Innovation in Government

Energy Technology Data Exchange (ETDEWEB)

Mahroum, S.

2016-07-01

Over the past few decades, there has been growing interest in supporting innovation in the public sector as a means of increasing the efficiency and quality of government services. Generally speaking, innovation in government could be defined as “The creation and implementation of new processes, products, services and methods of delivery which result in significant improvements in outcome efficiency, effectiveness or quality’’ [3]. A ‘Process Innovation’ is an activity oriented mainly towards enhancing ‘efficiency’. A ‘Product or Service Innovation’ is an activity oriented mainly towards enhancing the ‘effectiveness’ of government. A ‘Policy Innovation’ is mainly oriented at enhancing outcomes. These categorisations are important for identifying and selecting the metrics of measurement and to make distinctions between inputs, outputs, and outcomes. (Author)

2009-09-01

Full Text Available The distribution and life cycle of wild radish (Raphanus raphanistrum L. and a survey of the pathogens of this plant are reported for the northern regions of Tunisia. Wild radish is a common weed of cereal crops and legumes. It germinates in early autumn (October, develops a rosette stage in November to December after which stem growth, fl owering and pod production occur through to May, with pod maturity completed in June. Fungus isolation from the foliar tissues exhibiting disease symptoms showed that wild radish was infected with the fungi Albugo candida, Alternaria spp. including A. brassicicola, and A. raphani, Erysiphe cruciferarum, Stemphylium herbarum, Peronospora parasitica and Phoma lingam. Ascochyta spp., Cercospora armoraciae, Cladosporium cladosporioides and Colletotrichum higginsianum are here reported from wild radish for the first time. Inoculation tests of pathogens on wild radish plants showed that the most injurious fungi were Alternaria raphani and Phoma lingam. The remaining pathogens were weakly to moderately aggressive on this weed. To access the pathogenic effect of fungi spontaneously infecting natural populations of wild radish, the weed was grown in a field experiment with and without the broad-spectrum systemic fungicide Carbendazim. Results showed a statistically significant two-fold decrease in the number and weight of seed pods in the non-treated plants, indicating that the reproductive potential of wild radish was naturally reduced by fungal infection. Foliar pathogenic fungi have a potential in the integrated weed management of wild radish, this role merits further investigations.

The effects of Mycoplasma gallisepticum (MG) infections on egg production, fertility, and hatchability were studied in captive-reared wild turkeys (Meleagris gallopavo). Three groups of adult birds, each consisting of four hens and two toms, were exposed to MG by the respiratory route at the beginning of their breeding season. Fourteen control birds received sterile growth medium. Although no mortality of infected or control birds occurred, egg production during the first breeding season after infection was reduced. The mean number of eggs/hen/day produced by infected groups the first breeding season postexposure (PE) was significantly lower than the control value. The mean number of eggs produced daily by the same hens 1 yr later was unaffected by MG infection. The pecentage of fertile eggs produced by infected groups was slightly reduced in both the first and second breeding seasons PE. Hatchability of fertile eggs from infected hens was significantly lower than eggs from control hens. Productivity may be impaired if MG infections occur in free-ranging wild turkey populations.

How they affect the development product of Albania, not only as a concept, and a principle but mostly as a sensitive aspect in the integration process. There are some interpretations of this concept, but I intend to analyze the key factors and actors, their cooperation and concrete production in society. Improving governance is necessary to have an integrated long term strategy based upon a continuous cooperation between institutions and citizens. But in developing countries like Albania there are some important questions such as: How can we measure the improvement of Good Governance through policies? Has Good Governance indicated an effective way for the sustainable development? (Meisel, 2008, 6. These question give us the orientation to reflect about the process of development, social economic political behavior and how this multidimensional is transformed in product of good governance. The business cycle is strongly connected with many aspects of political-, social-, juridical aspects and good governance. Despite attempts to draft law regulations, the level of corruption and informality in Albania continues to be a major obstacle. The credibility level in the implementation of law is an indicator that affects democratization and institutional integration. At present, different reports of international institutions, define Albania as the country with the highest level of Corruption in the Balkans, which is a key factor influencing business.

Maria Elena Marescotti

2018-06-01

Full Text Available Although wild game meat constitutes a sustainable and healthy alternative to conventional meat and hunting contributes to the control of game populations, international studies on consumer attitudes towards this type of meat are still limited and no previous research has been focused on the Italian population. For the development of successful marketing strategies and/or public policy intervention, the knowledge of consumers’ purchase behavior is a key factor. Among all the determinants that can influence the behavior of consumers of hunted wild game meat (i.e. animal welfare, sustainability, ecological food choice, product safety, nutritional quality, the consumers’ awareness of hunting activity and their perceptions of wild game meat assume a crucial role. Accordingly, in this paper an online survey on a sample of 741 Italian meat consumers has been conducted to investigate the relationship between consumers’ purchase behavior and their awareness of hunted game meat and hunting practices (chi-square test, F-test. Statistically significant differences were found among segments of consumers with different levels of wild game meat consumption frequency. The analysis shows that, as expected, the highest consumption level of wild game meat relates to the highest level of general awareness of wild game meat and hunting practices. Our findings are in line with previous literature, that links positive behaviors of consumers towards wild game meat and hunting to familiarity and experience with hunting and hunters. Nonetheless, the present study provides a deeper understanding of the Italian consumers’ attitudes and perceptions of wild game meat and could suggests policy guidelines for the development of future targeted marketing strategies.

Wild cassava, Manihot spp.: Biology and potentialities for genetic improvement

Nassar Nagib M.A.

2000-01-01

Full Text Available Wild species of Manihot are progenitors of cassava. They constitute valuable genetic reservoirs presenting genes that show new characters. Screening of these species showed some of them to have a notably high percentage of protein combined with a low percentage of hydrocyanic acid. Study of natural habitats revealed resistance to drought and excessive soil aluminum toxicity as well as adaptation to low temperature. Some of the hybrids obtained showed high root productivity and resistance to stem borers. Apomixis was discovered in the wild and transferred successfully to the cultivate species.

Digital government and public health.

Science.gov (United States)

Fountain, Jane E

2004-10-01

Digital government is typically defined as the production and delivery of information and services inside government and between government and the public using a range of information and communication technologies. Two types of government relationships with other entities are government-to-citizen and government-to-government relationships. Both offer opportunities and challenges. Assessment of a public health agency's readiness for digital government includes examination of technical, managerial, and political capabilities. Public health agencies are especially challenged by a lack of funding for technical infrastructure and expertise, by privacy and security issues, and by lack of Internet access for low-income and marginalized populations. Public health agencies understand the difficulties of working across agencies and levels of government, but the development of new, integrated e-programs will require more than technical change - it will require a profound change in paradigm.

Carlos Sánchez García-Abad

2012-04-01

Full Text Available Despite the importance of rearing wild lagomorphs in captivity for hunting and predator conservation in Spain, little is known about this production sector.  Taking official data into account, in this work the number and distribution of farms in Spain and the possible number of animals produced were analysed during the period 2005-2010.  In 2010, 114 wild rabbit farms were widely distributed throughout the country (especially Catalonia, Galicia, Andalusia and Castile-La Mancha regions, while 21 hare farms were registered, the majority in Extremadura, Castile-La Mancha and Andalusia.  A possible production figure of 225000-265000 rabbits and 1034 hares was estimated in 2010.  Game farms of wild lagomorphs are established in Spain and placement would be related to a high demand for hunting and predator conservation in certain regions. Although more research is needed, the number of animals produced would be an important part of the total animals released to the wild.

Weiner Marcin

2016-12-01

Full Text Available Introduction: Although HEV infection in pigs does not pose a major economic risk to pork production, the risk of zoonotic transmission to humans is an important aspect of public health. HEV genotype 3 infections were reported in developed countries in individuals who had consumed raw meat or meat products from deer, wild boars, or pigs. The aim of the study was the analysis of the occurrence of HEV-specific antibodies among wild boars and domestic pigs in Poland. Material and Methods: A total of 290 samples from wild boars and 143 samples from pigs were tested. The antibodies were tested by ELISA. Results: The presence of anti-HEV IgG was demonstrated in 44.1% of pigs and 31.0% of wild boars. Anti-HEV IgG antibodies were detected in 1.4% of samples from pigs and in 2.1% of samples from wild boars at borderline level. The statistical analysis shows significant differences in the positive results for anti-HEV IgG between the groups of pigs and wild boars (P = 0.0263. Conclusion: Regular surveillance of the occurrence of HEV in swine and wild boars should be performed in the future.

Is a wild mammal kept and reared in captivity still a wild animal?

Künzl, Christine; Kaiser, Sylvia; Meier, Edda; Sachser, Norbert

2003-01-01

This study compared domestic guinea pigs (Cavia aperea f. porcellus; DGP) and two different populations of the wild cavy (Cavia aperea), its ancestor, to examine whether rearing of wild mammals in captivity affects their behavior and physiological stress responses. One population of wild cavies consisted of wild-trapped animals and their first laboratory-reared offspring (WGP-1). The animals of the other population were reared in captivity for about 30 generations (WGP-30). The spontaneous behavior of each of six groups of WGP-1 and WGP-30 and nine groups of DGP, each consisting of one adult male and two adult females, was analyzed quantitatively. Blood samples of the males were taken to determine cortisol, epinephrine, and norepinephrine concentrations. In addition, the exploratory behavior of 60-day-old male WGP-1, WGP-30, and DGP was investigated in an exploration apparatus. The domesticated animals displayed significantly less aggression, but significantly more sociopositive and male courtship behavior than their wild ancestors. In addition, DGP were much less attentive to their physical environment. Surprisingly, no behavioral difference was found between WGP-1 and WGP-30. Basal cortisol concentrations did not differ between wild and domestic guinea pigs. Catecholamine concentrations, however, as well as the challenge values of cortisol, were distinctly reduced in the DGP. WGP-1 and WGP-30 did not differ with respect to their endocrine stress responses. In the exploration apparatus both forms of wild cavies were much more explorative than the domestic animals. These data suggest that the long-term breeding and rearing of wild guinea pigs in captivity do not result in significant changes in behavior and hormonal stress responses. It appears to take much longer periods of time and artificial selection by humans to bring about characters of domestication in wild animals.

The major bottlenecks in achieving competitive bioethanol fuel are the high cost of feedstock, energy and enzymes employed in pretreatment prior to fermentation. Lignocellulosic biomass has been proposed as an alternative feedstock, but because of its complexity, economic viability is yet to be realized. Therefore, research around non-conventional feedstocks and deployment of bioconversion approaches that downsize the cost of energy and enzymes is justified. In this study, a non-conventional feedstock, inedible wild cassava was used for bioethanol production. Bioconversion of raw starch from the wild cassava to bioethanol at low temperature was investigated using both a co-culture of Aspergillus sp. and Saccharomyces cerevisiae, and a monoculture of the later with enzyme preparation from the former. A newly isolated strain of Aspergillus sp. MZA-3 produced raw starch-degrading enzyme which displayed highest activity of 3.3 U/mL towards raw starch from wild cassava at 50°C, pH 5.5. A co-culture of MZA-3 and S. cerevisiae; and a monoculture of S. cerevisiae and MZA-3 enzyme (both supplemented with glucoamylase) resulted into bioethanol yield (percentage of the theoretical yield) of 91 and 95 at efficiency (percentage) of 84 and 96, respectively. Direct bioconversion of raw starch to bioethanol was achieved at 30°C through the co-culture approach. This could be attractive since it may significantly downsize energy expenses.

Kibale forest wild coffee: challenges to market-based conservation in Africa.

Science.gov (United States)

Lilieholm, Robert J; Weatherly, W Paul

2010-08-01

Declining rural security and pressures to reduce public-sector expenditures in the late 1990s spurred efforts to develop alternative funding models for Uganda's Kibale National Park (KNP). The Wild Coffee Project, established in 1999 with support from the U.S. Agency for International Development, the World Bank, and the Ford Foundation, sought to develop a market for wild coffee that had been harvested traditionally from areas within today's KNP. The Kibale Forest Foundation, a U.S.-based nonprofit organization, was created to legalize harvests, obtain third-party wild and organic certification, and coordinate management between KNP, the coffee industry, and local communities. Although the project was successful in legalizing, harvesting, and processing the world's first certified wild and organic coffee, efforts to gain entry into the international marketplace failed. Chief among the lessons learned from this project is that for many wild-grown products, the value of "the story"--in both human and conservation terms--is likely to far exceed actual product values. This value differential should be captured through high-value niche markets to avoid low commodity pricing and subsequent pressures to improve financial returns through over harvesting. In addition, local producers should hold significant assets in whatever brands are developed, creating a shared-equity approach that serves social responsibility goals, fosters project sustainability, and ensures a steady stream of positive stories for use in marketing to build brand value. Shared equity--in this case ownership interest in the intellectual property embodied in the brand--provides a second incentive beyond transactional profits that can only be realized if resource conservation is maintained.

Wild Boar Impact to the Natural Regeneration of Oak and Acorn Importance in its Diet

Full Text Available In this study, the impact of wild boar on the natural regeneration of oak and importance of acorns in the wild boar diet were surveyed. The data were collected near Moravian Krumlov (Czech Republic in three types of oak stands differing in the canopy density: fully-stocked stand (1, open-canopy stand (2 and the forest stand in a conversion to the coppice forest (3. Within each stand 150 m long lines were set out. Seed traps to collect acorn harvest and control plots were installed on these lines. The plots were inspected at weekly intervals. After the end of acorn fall the average amount of fallen acorns was evaluated. The quantity of metabolizable energy in acorns was assessed and daily survival dose of energy for average weight of wild boar was counted. In spring 2014 the number of seedlings was counted at the same plots. Production of acorns per hectare and basic energy needs for one individual wild boar per day were evaluated for each chosen stand type. The found seedling density amounted to 29,600, 32,000 and 14,000 ind./ha in the first, second and third stand under study, respectively. Wild boar is a major consumer of acorns. In the studied area the production of acorns sufficiently supplied the local wild boar population during winter. Necessary amount of acorns remained for the natural regeneration.

.H.Wilson fruits of 0.5 MT in 2009, annual quantities steadily increased up to 30 MT sold in 2017. The cooperative achieved organic certification in 2012. In 2016, governmental authorisation for the certification of Chinese operations implementing the FairWild Standard was granted. In 2017, the Giant Panda Friendly Products Standard became an official Chinese standard with the cooperative becoming the first panda-friendly certified operation in 2018. A decade after the project first started, there is strong evidence for the pro-conservation micro- and small enterprise model. For example, through the establishment of a TCM cooperative with members in 22 villages engaged in sustainable resource management, harvesting and equitable trade of TCM ingredients with organic and panda-friendly branding. The project benefited from multi-disciplinary collaboration of experts in ethnoecology, TCM, panda biology and habitat, nature conservation, sustainability standards and international trade. Inviting interested companies at the start enabled a transition from a funded-project to annual contracts for sustainably harvested TCM herbal drugs. At end of project (2011), the companies and NGOs remained engaged and motivating for completion of activities started during the project. Major eventual outcomes rooted in the initial project included Chinese government authorisation of the FairWild Standard (2016) and Giant Panda Friendly Products Standard (2017). Copyright © 2018.

Factors Affecting the Distribution of Wild Rice (Zizania palustris) and the Surrounding Macrophyte Community.

Science.gov (United States)

Pillsbury, R. W.; McGuire, M.

2005-05-01

A recent decline in wild rice wetlands is cause for concern due to its importance as a food source, refuge for wildlife, and cultural significance. Sixty wetlands in Wisconsin and Minnesota (USA) were sampled, with approximately equal numbers displaying dense, moderate and sparse wild rice production. Chemical, physical, and watershed parameters were measured as well as macrophyte densities. Data were analyzed using multivariate statistics (CCA). Moderate levels of phosphorus appear beneficial to the overall success of wild rice, while free-floating macrophytes show an overwhelming positive response to higher levels of P. The distribution of macrophytes bordering wild rice beds is correlated to pH,with Potamogeton robbinsii and filamentous green algae responding most strongly to its increase. Healthy stands of wild rice exhibit a narrow circum-neutral range of pH (6.1-8.0)which is significantly different from the greater range exhibited by sparse wild rice wetlands (6.5-8.5). This pattern was paralleled when considering depth which suggests that deeper wetlands may be more susceptible to wild rice loss. Management of existing wild rice wetlands should focus monitoring on pH, depth, phosphorus concentrations and shore development. We are currently using this data base to locate the best reintroduction sites for wild rice.

Impact of honeybee (Apis mellifera L. density on wild bee foraging behaviour

Goras Georgios

2016-06-01

Full Text Available Honey bees are globally regarded as important crop pollinators and are also valued for their honey production. They have been introduced on an almost worldwide scale. During recent years, however, several studies argue their possible competition with unmanaged pollinators. Here we examine the possible effects of honey bees on the foraging behaviour of wild bees on Cistus creticus flowers in Northern Greece. We gradually introduced one, five, and eight honey-bee hives per site, each containing ca. 20,000 workers. The visitation frequency and visit duration of wild bees before and after the beehive introductions were measured by flower observation. While the visitation frequencies of wild bees were unaffected, the average time wild bees spent on C. creticus increased with the introduction of the honey-bee hives. Although competition between honey bees and wild bees is often expected, we did not find any clear evidence for significant effects even in honey-bee densities much higher than the European-wide average of 3.1 colonies/km2.

Public Procurement and Forest Governance: A German Case Study of Governmental Influences on Market-Driven Governance Systems

Directory of Open Access Journals (Sweden)

Moritz Albrecht

2012-09-01

Full Text Available With increased privatization of natural resource regulation, green or sustainable public procurement policies are emerging as incentives for sustainable development. Thus, a revival of governmental influences on so-called non-state, market-driven governance systems takes place. The paper exemplifies this development by reference to the green public procurement directives for wood products in Germany and its influence on major forest certification systems and forest governance. Using an approach of governmentality in relational space, the paper displays how governmental entities play a significant role in influencing forest governance systems and the greening of markets. The importance of the underlying relations that shape governmental instruments and their influences on forest certification and governance are evaluated from a German perspective. Acknowledging the market-driven aspects of forest certification systems, the paper highlights the often-neglected impacts of governmental regulation on emerging forest governance systems. Thus, the framework allows insights into how relations among political entities and their means of knowledge production are essential for processes of forest governance.

The wild type as concept and in experimental practice: A history of its role in classical genetics and evolutionary theory.

Science.gov (United States)

Holmes, Tarquin

2017-06-01

Wild types in genetics are specialised strains of laboratory experimental organism which principally serve as standards against which variation is measured. As selectively inbred lineages highly isolated from ancestral wild populations, there appears to be little wild or typical about them. I will nonetheless argue that they have historically been successfully used as stand-ins for nature, allowing knowledge produced in the laboratory to be extrapolated to the natural world. In this paper, I will explore the 19th century origins of the wild type concept, the theoretical and experimental innovations which allowed concepts and organisms to move from wild nature to laboratory domestication c. 1900 (resulting in the production of standardised lab strains), and the conflict among early geneticists between interactionist and atomist accounts of wild type, which would eventually lead to the conceptual disintegration of wild types and the triumph of genocentrism and population genetics. I conclude by discussing how the strategy of using wild type strains to represent nature in the lab has nonetheless survived the downfall of the wild type concept and continues to provide, significant limitations acknowledged, an epistemically productive means of investigating heredity and evolutionary variation.

Xian-hua SHEN

2013-09-01

Full Text Available This study was conducted to develop and characterize a novel cytoplasmic male sterile (CMS source which was identified from Dongxiang wild rice (Oryza rufipogon by crossing Dongxiang wild rice as female with Zhongzao 35, an indica inbred variety, as male and continuous backcrossing with Zhongzao 35. Observation under optical microscope manifested that this novel CMS belonged to typical abortion type with less pollen compared with wild abortive type cytoplasm (CMS-WA. Sequential planting showed that this novel CMS has complete and stable male sterility. Testcross experiment showed that all the 24 tested materials including maintainer and restorer lines of CMS-WA and Honglian type cytoplasm (CMS-HL and other indica inbred varieties are the maintainers with complete maintaining ability, suggesting that this novel CMS has fertility restoration totally different from CMS-WA and CMS-HL and belongs to a novel type of CMS. So far, we only discovered a unique fertility restoration source for this novel CMS. Inheritance analysis showed that the fertility restoration of this CMS was governed by three pairs of independent dominant genes. Prospect for application of this novel CMS system in hybrid rice breeding was also discussed.

Full Text Available Glycopeptides (GPAs are an important class of antibiotics, with vancomycin and teicoplanin being used in the last 40 years as drugs of last resort to treat infections caused by Gram-positive pathogens, including methicillin-resistant Staphylococcus aureus. A few new GPAs have since reached the market. One of them is dalbavancin, a derivative of A40926 produced by the actinomycete Nonomuraea sp. ATCC 39727, recently classified as N. gerenzanensis. This review summarizes what we currently know on the multilevel regulatory processes governing production of the glycopeptide A40926 and the different approaches used to increase antibiotic yields. Some nutrients, e.g., valine, l-glutamine and maltodextrin, and some endogenous proteins, e.g., Dbv3, Dbv4 and RpoBR, have a positive role on A40926 biosynthesis, while other factors, e.g., phosphate, ammonium and Dbv23, have a negative effect. Overall, the results available so far point to a complex regulatory network controlling A40926 in the native producing strain.

2017-01-19

Agriculture is a dominant evolutionary force that drives the evolution of both domesticated and wild species. However, the various mechanisms of agriculture-induced evolution and their socio-ecological consequences are not often synthetically discussed. Here, we explore how agricultural practices and evolutionary changes in domesticated species cause evolution in wild species. We do so by examining three processes by which agriculture drives evolution. First, differences in the traits of domesticated species, compared with their wild ancestors, alter the selective environment and create opportunities for wild species to specialize. Second, selection caused by agricultural practices, including both those meant to maximize productivity and those meant to control pest species, can lead to pest adaptation. Third, agriculture can cause non-selective changes in patterns of gene flow in wild species. We review evidence for these processes and then discuss their ecological and sociological impacts. We finish by identifying important knowledge gaps and future directions related to the eco-evolutionary impacts of agriculture including their extent, how to prevent the detrimental evolution of wild species, and finally, how to use evolution to minimize the ecological impacts of agriculture.This article is part of the themed issue 'Human influences on evolution, and the ecological and societal consequences'. © 2016 The Author(s).

Essential Features of Responsible Governance of Agricultural Biotechnology.

Hartley, Sarah; Gillund, Frøydis; van Hove, Lilian; Wickson, Fern

2016-05-01

Agricultural biotechnology continues to generate considerable controversy. We argue that to address this controversy, serious changes to governance are needed. The new wave of genomic tools and products (e.g., CRISPR, gene drives, RNAi, synthetic biology, and genetically modified [GM] insects and fish), provide a particularly useful opportunity to reflect on and revise agricultural biotechnology governance. In response, we present five essential features to advance more socially responsible forms of governance. In presenting these, we hope to stimulate further debate and action towards improved forms of governance, particularly as these new genomic tools and products continue to emerge.

Wild bee communities provide underappreciated but critical agricultural pollination services. Given predicted global shortages in pollination services, managing agroecosystems to support thriving wild bee communities is, therefore, central to ensuring sustainable food production. Benefits of natural (including semi-natural) habitat for wild bee abundance and diversity on farms are well documented. By contrast, few studies have examined toxicity of pesticides on wild bees, let alone effects of farm-level pesticide exposure on entire bee communities. Whether beneficial natural areas could mediate effects of harmful pesticides on wild bees is also unknown. Here, we assess the effect of conventional pesticide use on the wild bee community visiting apple (Malus domestica) within a gradient of percentage natural area in the landscape. Wild bee community abundance and species richness decreased linearly with increasing pesticide use in orchards one year after application; however, pesticide effects on wild bees were buffered by increasing proportion of natural habitat in the surrounding landscape. A significant contribution of fungicides to observed pesticide effects suggests deleterious properties of a class of pesticides that was, until recently, considered benign to bees. Our results demonstrate extended benefits of natural areas for wild pollinators and highlight the importance of considering the landscape context when weighing up the costs of pest management on crop pollination services. © 2015 The Author(s) Published by the Royal Society.

Disaster Governance and Vulnerability: The Case of Chile

Directory of Open Access Journals (Sweden)

Vicente Sandoval

2016-12-01

Full Text Available This exploratory work seeks to shed light on disaster governance by looking into potential linkages between the production of vulnerability and disaster governance in Chile. Our point of investigation is the case of post-disaster Chaitén and the Chilean model of Disaster Risk Management. The work begins by situating disaster governance and the production of vulnerability in a broader context of existing governance system that includes a multiplicity of actors and socio-economic, socio-ecological, and political processes. Coming from a multi-scalar perspective, we use the disaster Pressure and Release (PAR model to enable a differentiated analysis of the multiplicity of actors, rules, and processes related to DRM that participate in the production of disaster vulnerability in the current Chaitén. With this we address the questions as to ‘why’ the Chilean model of DRM is prominently centralised and ‘what’ are the effects on the production of disaster vulnerability for the case of post-disaster Chaitén.

Locally harvested wild edible plants (WEPs) provide food as well as cash income for indigenous people and are of great importance in ensuring global food security. Some also play a significant role in maintaining the productivity and stability of traditional agro-ecosystems. Shangri-la region of Yunnan Province, SW China, is regarded as a biodiversity hotspot. People living there have accumulated traditional knowledge about plants. However, with economic development, WEPs are threatened and the associated traditional knowledge is in danger of being lost. Therefore, ethnobotanical surveys were conducted throughout this area to investigate and document the wild edible plants traditionally used by local Tibetan people. Twenty-nine villages were selected to carry out the field investigations. Information was collected using direct observation, semi-structured interviews, individual discussions, key informant interviews, focus group discussions, questionnaires and participatory rural appraisal (PRA). Information about 168 wild edible plant species in 116 genera of 62 families was recorded and specimens were collected. Most species were edible greens (80 species) or fruits (78). These WEPs are sources for local people, especially those living in remote rural areas, to obtain mineral elements and vitamins. More than half of the species (70%) have multiple use(s) besides food value. Some are crop wild relatives that could be used for crop improvement. Several also have potential values for further commercial exploitation. However, the utilization of WEPs and related knowledge are eroding rapidly, especially in the areas with convenient transportation and booming tourism. Wild food plants species are abundant and diverse in Shangri-la region. They provide food and nutrients to local people and could also be a source of cash income. However, both WEPs and their associated indigenous knowledge are facing various threats. Thus, conservation and sustainable utilization of these

Full Text Available The radiocaesium activity concentration may still remain high in natural products such as game meat, wild mushrooms, and forest berries even more than two decades after the Chernobyl accident. The results of regular control studies of game meat conducted in Poland showed wild boars as the most contaminated game animals. It is well documented that some mushrooms, readily consumed by animals, show high ability to accumulate caesium radioisotopes. Bay bolete, one of the most wide-spread mushroom species in Poland, reveals a unique radiocaesium accumulation feature. Moreover, deer truffle, containing also particularly high levels of radiocaesium, could be another radionu-clide source for wild boars. Furthermore, animals consuming deer truffles could digest contaminated soil components. Among 94 wild boar meat samples analysed in 2008–2009, two exceeded the permitted level. Hence, some precautions should be taken in the population with an elevated intake of wild boar meat. Moreover, since each hunted wild boar is examined for the presence of Trichinella larvae, regular measurements of radiocaesium concentrations in these animals may be advisable for enhancing consumer safety.

Full Text Available According to the modern nutritionist opinions, cereal products such as flakes and snacks are the most common foods in the daily diet. Extrusion technology makes it possible to apply different sources of ingredients for the enrichment of cereal-based flakes or snack products. Substances with strong antioxidant properties such as wild oregano have a positive impact on human health. Therefore, they attract the attention of scientists, consumers and food industry experts. This paper investigates the effects of the simultaneous addition of dry residue from wild oregano distillation (0.5 g / 100g of sample and 1 g / 100g of sample, on the physical-textural and color properties of corn flakes in order to create a new product with improved nutritional properties. The addition of dry residue of wild oregano positively influenced physical characteristics (decreased bulk density 30.2 %, increased expansion rate 44.9 %, as well as texture hardness and the work of compression, 38.1 % and 40.3 %, respectively. Also, oregano significantly changed the color of flakes. Tukey’s HSD test showed statistically significant differences between most of the mean values of physical-textural, color and sensory attributes in the oregano-added corn flakes compared to the control sample. Principal component analysis has been applied to classify the samples according to differences in the studied parameters. The data pointed out that investigated corn flakes with the addition of wild oregano are new food products with good physical-textural and sensory properties due to a higher level of antioxidant activity. Moreover, it may contribute to the valorization of edible industrial waste in food production. [Projekat Ministarstva nauke Republike Srbije, br. III 46005 i br. TR 31027

Mialoundama, Alexis Samba; Heintz, Dimitri; Debayle, Delphine; Rahier, Alain; Camara, Bilal; Bouvier, Florence

2009-07-01

In the Solanaceae, biotic and abiotic elicitors induce de novo synthesis of sesquiterpenoid stress metabolites known as phytoalexins. Because plant hormones play critical roles in the induction of defense-responsive genes, we have explored the effect of abscisic acid (ABA) on the synthesis of capsidiol, the major wild tobacco (Nicotiana plumbaginifolia) sesquiterpenoid phytoalexin, using wild-type plants versus nonallelic mutants Npaba2 and Npaba1 that are deficient in ABA synthesis. Npaba2 and Npaba1 mutants exhibited a 2-fold higher synthesis of capsidiol than wild-type plants when elicited with either cellulase or arachidonic acid or when infected by Botrytis cinerea. The same trend was observed for the expression of the capsidiol biosynthetic genes 5-epi-aristolochene synthase and 5-epi-aristolochene hydroxylase. Treatment of wild-type plants with fluridone, an inhibitor of the upstream ABA pathway, recapitulated the behavior of Npaba2 and Npaba1 mutants, while the application of exogenous ABA reversed the enhanced synthesis of capsidiol in Npaba2 and Npaba1 mutants. Concomitant with the production of capsidiol, we observed the induction of ABA 8'-hydroxylase in elicited plants. In wild-type plants, the induction of ABA 8'-hydroxylase coincided with a decrease in ABA content and with the accumulation of ABA catabolic products such as phaseic acid and dihydrophaseic acid, suggesting a negative regulation exerted by ABA on capsidiol synthesis. Collectively, our data indicate that ABA is not required per se for the induction of capsidiol synthesis but is essentially implicated in a stress-response checkpoint to fine-tune the amplification of capsidiol synthesis in challenged plants.

Abstract Background Domestic animals and their wild relatives differ in a wide variety of aspects. The process of domestication of the domestic guinea pig (Cavia aperea f. porcellus), starting at least 4500 years ago, led to changes in the anatomy, physiology, and behaviour compared with their wild relative, the wild cavy, Cavia aperea. Although domestic guinea pigs are widely used as a laboratory animal, learning and memory capabilities are often disregarded as being very scarce. Even less i...

A new wild strain of Saccharomyces cerevisiae (CF3) isolated from tequila must was evaluated for production of fructanase on Agave tequilana Weber fructan (FT). Fructanase activity (F) was assessed by a 3(3) factorial design (substrate, temperature and pH). High enzymatic activity (31.1 U/ml) was found at 30 °C, pH 5, using FT (10 g/l) as substrate. The effect of initial substrate concentration on F (FT0, 5.7-66 g/l) was studied and it was found that F was highest (44.8 U/ml) at FT0 25 g/l. A 2(2) factorial experimental design with five central points was utilized to study the effect of stirring and aeration on fructanase activity; stirring exhibited a stronger effect on F. The ratio fructanase to invertase (F/S) was 0.57, which confirms that the enzymes are fructanase. Crude fructanase reached high substrate hydrolysis (48 wt%) in 10 h. It is shown that S. cerevisiae CF3 was able to produce large amounts of fructanase by growing it on fructan from A. tequilana.

Most fungal genomes are poorly annotated, and many fungal traits of industrial and biomedical relevance are not well suited to classical genetic screens. Assigning genes to phenotypes on a genomic scale thus remains an urgent need in the field. We developed an approach to infer gene function from expression profiles of wild fungal isolates, and we applied our strategy to the filamentous fungus Neurospora crassa. Using transcriptome measurements in 70 strains from two well-defined clades of this microbe, we first identified 2,247 cases in which the expression of an unannotated gene rose and fell across N. crassa strains in parallel with the expression of well-characterized genes. We then used image analysis of hyphal morphologies, quantitative growth assays, and expression profiling to test the functions of four genes predicted from our population analyses. The results revealed two factors that influenced regulation of metabolism of nonpreferred carbon and nitrogen sources, a gene that governed hyphal architecture, and a gene that mediated amino acid starvation resistance. These findings validate the power of our population-transcriptomic approach for inference of novel gene function, and we suggest that this strategy will be of broad utility for genome-scale annotation in many fungal systems. IMPORTANCE Some fungal species cause deadly infections in humans or crop plants, and other fungi are workhorses of industrial chemistry, including the production of biofuels. Advances in medical and industrial mycology require an understanding of the genes that control fungal traits. We developed a method to infer functions of uncharacterized genes by observing correlated expression of their mRNAs with those of known genes across wild fungal isolates. We applied this strategy to a filamentous fungus and predicted functions for thousands of unknown genes. In four cases, we experimentally validated the predictions from our method, discovering novel genes involved in the

Meat products from HEV-infected reservoir animal species are capable of transmitting HEV to humans and represent a public health concern. Human HEV cases have been linked to the consumption of raw or undercooked pig liver sausages, pork, and game meats, such as wild boars and deer worldwide. Direct exposure to swine or wild game species might also represent a source of HEV transmission especially for veterinarians, hunters, or butchers. A limited amount of data is available on HEV prevalence in wild boars in Italy and no data are available for other wild game species intended for human consumption. In this study, the circulation of HEV in four different animal species hunted in north-western Italy was evaluated to gain insight into the infection levels and the genetic diversity of the virus in such animal populations. Liver samples of 372 wild boars, 30 roe deer, 47 European hares and 38 coypus were analyzed for HEV RNA by real-time RT-PCR; positive samples were then sequenced and submitted to phylogenetic analysis. HEV RNA was detected in the livers of 7/372 (1.9%) wild boars tested, while no sample was positive for roe deer, European hare, and coypu. Phylogenetic analysis showed that wild boar HEV sequences belonged to HEV subtypes 3e, 3c, and 3f. Our results indicate that HEV is circulating only in wild boar among the considered game species in north-western Italy and suggest a potential zoonotic risk related to handling and/or consumption of raw or undercooked meat and products made of the liver from this species.

2018-02-18

Avian metapneumovirus (aMPV) is an emerging poultry pathogen that has a significant economic impact on poultry production worldwide. The geographic range of the virus continues to expand, and wild birds have been implicated as reservoirs of aMPV that have the potential to spread the virus over long distances. Our objective was to determine the apparent prevalence of aMPV subtype C in wild waterfowl in Ontario, Canada. Wild waterfowl were captured in August and September, 2016 as part of routine migratory waterfowl population monitoring by the Ontario Ministry of Natural Resources and Forestry. Oropharyngeal and cloacal swabs were collected from each bird and placed together for aMPV testing using real-time RT-PCR. A total of 374 live wild birds from 23 lakes were sampled and tested for aMPV. Among all ducks tested, 84 (22%) were positive for aMPV. The proportion of samples that tested positive ranged from 0% in ring-necked ducks (Aythya collaris) and green-winged teal (Anas carolinensis) to 44% (8 of 18) in American black ducks (A. rubripes). Waterfowl positive for aMPV were found at 14 of 23 lakes in the study area and the percent positive at these 14 lakes ranged between 5% and 84%. Although subtype C aMPV has been detected in a variety of wild birds in North America, this is the first report of aMPV in wild ducks in Ontario, Canada. The high apparent prevalence, particularly in mallards and American black ducks (37 and 44%, respectively), suggests that these species may be important reservoirs of aMPV. Given the potential impact of aMPV on domestic poultry and the potential role of wild birds as reservoirs of the virus, further investigation of the geographic distribution, risk factors associated with aMPV carriage in wild waterfowl and potential role of other birds in the epidemiology of aMPV in Canada is warranted. © 2018 Blackwell Verlag GmbH.

2017-11-01

Coronary artery disease (CAD) has emerged as a leading cause of death in Indonesia nowadays. WHO data in 2012 revealed that 37% of the Indonesian population died from this disease. CAD occurs because of endothelial dysfunction in the arteries. Lipoprotein-associated phospholipase A2 (Lp-PLA2), also known as platelet-activating factor acetylhydrolase (PAF-AH), is a phospholipase A2 enzyme, encoded by the PLA2G7 gene. This protein is predicted to be involved in inflammatory phospholipid metabolism so it can be used as a biomarker of CAD in the early phase. Thus, the purpose of this research is to discover the difference in antibody production between wild-type and mutant V279F. The PAF-AH enzyme was isolated from mice lymphocyte cells in order to develop this enzyme as a biomarker of cardiovascular disease. PAF-AH migrates at 55kDa according to SDS-PAGE analysis. Flow cytometry analysis showed that mutant PAF-AH (V279F) is more antigenic than wild-type PAF-AH. The missense mutation of V279F PAF-AH means this enzyme cannot catabolize the acetyl group at the sn-2 position of PAF.

Crop-to-wild gene flow can reduce the fitness and genetic integrity of wild species. Malus sylvestris , the European crab-apple fruit tree in particular, is threatened by the disappearance of its habitat and by gene flow from its domesticated relative , Malus domestica . With the aims of evaluating threats for M. sylvestris and of formulating recommendations for its conservation, we studied here, using microsatellite markers and growth experiments: (i) hybridization rates in seeds and trees from a French forest and in seeds used for replanting crab apples in agrosystems and in forests, (ii) the impact of the level of M. domestica ancestry on individual tree fitness and (iii) pollen dispersal abilities in relation to crop-to-wild gene flow. We found substantial contemporary crop-to-wild gene flow in crab-apple tree populations and superior fitness of hybrids compared to wild seeds and seedlings. Using paternity analyses, we showed that pollen dispersal could occur up to 4 km and decreased with tree density. The seed network furnishing the wild apple reintroduction agroforestry programmes was found to suffer from poor genetic diversity, introgressions and species misidentification. Overall, our findings indicate supported threats for the European wild apple steering us to provide precise recommendations for its conservation.

Understanding the likelihood and extent of introgression of novel alleles in hybrid zones requires comparison of lifetime fitness of parents and hybrid progeny. However, fitness differences among cross types can vary depending on biotic conditions, thereby influencing introgression patterns. Based on past work, we predicted that increased competition would enhance introgression between cultivated and wild sunflower (Helianthus annuus) by reducing fitness advantages of wild plants. To test this prediction, we established a factorial field experiment in Kansas, USA where we monitored the fitness of four cross types (Wild, F1, F2, and BCw hybrids) under different levels of interspecific and intraspecific competition. Intraspecific manipulations consisted both of density of competitors and of frequency of crop-wild hybrids. We recorded emergence of overwintered seeds, survival to reproduction, and numbers of seeds produced per reproductive plant. We also calculated two compound fitness measures: seeds produced per emerged seedling and seeds produced per planted seed.

Full Text Available Understanding the likelihood and extent of introgression of novel alleles in hybrid zones requires comparison of lifetime fitness of parents and hybrid progeny. However, fitness differences among cross types can vary depending on biotic conditions, thereby influencing introgression patterns. Based on past work, we predicted that increased competition would enhance introgression between cultivated and wild sunflower (Helianthus annuus by reducing fitness advantages of wild plants. To test this prediction, we established a factorial field experiment in Kansas, USA where we monitored the fitness of four cross types (Wild, F1, F2, and BCw hybrids under different levels of interspecific and intraspecific competition. Intraspecific manipulations consisted both of density of competitors and of frequency of crop-wild hybrids. We recorded emergence of overwintered seeds, survival to reproduction, and numbers of seeds produced per reproductive plant. We also calculated two compound fitness measures: seeds produced per emerged seedling and seeds produced per planted seed.

Full Text Available This study explored the rural revitalizing strategy in FAO's Globally Important Agricultural Heritage System (GIAHS site in Noto Peninsula, Ishikawa Prefecture of Japan, using a case study of edible wild plants. This study assessed the current and possible future utilization of edible wild plants as one important NTFP by clarifying the attitudes of consumers and exploring the challenges of harvesting edible wild plants. Traditional ecological knowledge associated with edible wild plants and the related attitudes of consumers towards wild plants was documented. A questionnaire survey found that a majority of the respondents held positive attitude towards edible wild plants as being healthy, safe food, part of traditional dietary culture. Increasing demand of edible wild plants from urban residents aroused conflicts with local residents’ interest given that around 86% of the forested hills are private in Noto Region. Non timber forest products (NTFP extraction can be seen as a tool for creating socioeconomic relationships that are dependent on healthy, biodiverse ecosystems. It was suggested that Japanese Agricultural Cooperatives (JA and Forestry Cooperatives (FCA could be involved with GIAHS process. As important traditional dietary and ecological system, edible wild plants should be a part of GIAHS project for rural revitalization.

Information of the difference in quality between farmed and wild fish is central to better ensuring fish products produced in aquaculture meet regulatory and consumer requirements. Proximate composition, amino acid and fatty acid profiles, and toxic elements contents of farmed and wild Chanodichthys mongolicus were established and compared. Significantly higher crude protein content while lower moisture content in farmed fish compared to wild fish were observed ( Pacids (TAA), total essential amino acids (TEAA), total non-essential amino acids (TNEAA) and total delicious amino acids (TDAA) in farmed fish were all significantly higher than those in the wild equivalent ( Pacid profiles in both farmed and wild C. mongolicus were dominated by monounsaturated fatty acid (MUFA), with farmed fish contained much more MUFA content compared to wild counterpart ( Pacid (PUFA) including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) than farmed fish ( Pacid (C18:2n6) were the predominant PUFA in wild and farmed C. mongolicus, respectively. Moreover, farmed fish displayed an overall lower toxic element levels (As, Cd, Pb and Hg) in comparison with wild fish, and both were far lower than the established limit standard. In conclusion, our results suggest that the nutritional quality of farmed C. mongolicus was inferior to their wild counterpart with respect to fatty acids nutrition, and therefore further studies should focus on the improving C. mongolicus diet in order to enhance the overall nutritional composition.

'Good Governance' dan 'Governability'

Directory of Open Access Journals (Sweden)

- Pratikno

2005-03-01

Full Text Available The article endeavors to trace the outset of governance concept, its dominant meanings and discourse, and its implication towards governability. The central role of government in the governing processes has predominantly been adopted. The concept of governance was emerged precisely in the context of the failure of government as key player in regulation, economic redistribution and political participation. Governance is therefore aimed to emphasize pattern of governing which are based both on democratic mechanism and sound development management. However, practices of such good governance concept –which are mainly adopted and promoted by donor states and agencies– tend to degrade state and/or government authority and legitimacy. Traditional function of the state as sole facilitator of equal societal, political and legal membership among citizens has been diminished. The logic of fair competition has been substituted almost completely by the logic of free competition in nearly all sectors of public life. The concept and practices of good governance have resulted in decayed state authority and failed state which in turn created a condition for "ungovernability". By promoting democratic and humane governance, the article accordingly encourages discourse to reinstall and bring the idea of accountable state back in.

Wild animals' meat is extensively consumed in South Africa, being obtained either from ranching, farming or hunting. To test the authenticity of the commercial labels of meat products in the local market, we obtained DNA sequence information from 146 samples (14 beef and 132 game labels) for barcoding cytochrome c oxidase subunit I and partial cytochrome b and mitochondrial fragments. The reliability of species assignments were evaluated using BLAST searches in GenBank, maximum likelihood phylogenetic analysis and the character-based method implemented in BLOG. The Kimura-2-parameter intra- and interspecific variation was evaluated for all matched species. The combined application of similarity, phylogenetic and character-based methods proved successful in species identification. Game meat samples showed 76.5% substitution, no beef samples were substituted. The substitutions showed a variety of domestic species (cattle, horse, pig, lamb), common game species in the market (kudu, gemsbok, ostrich, impala, springbok), uncommon species in the market (giraffe, waterbuck, bushbuck, duiker, mountain zebra) and extra-continental species (kangaroo). The mountain zebra Equus zebra is an International Union for Conservation of Nature (IUCN) red listed species. We also detected Damaliscus pygargus, which is composed of two subspecies with one listed by IUCN as 'near threatened'; however, these mitochondrial fragments were insufficient to distinguish between the subspecies. The genetic distance between African ungulate species often overlaps with within-species distance in cases of recent speciation events, and strong phylogeographic structure determines within-species distances that are similar to the commonly accepted distances between species. The reliability of commercial labeling of game meat in South Africa is very poor. The extensive substitution of wild game has important implications for conservation and commerce, and for the consumers making decisions on the basis of

Full Text Available Wild fruits are exotic or underutilized. Wild fruits contain many bioactive compounds, such as anthocyanins and flavonoids. Many studies have shown that wild fruits possess various bioactivities and health benefits, such as free radical scavenging, antioxidant, anti-inflammatory, antimicrobial, and anticancer activity. Therefore, wild fruits have the potential to be developed into functional foods or pharmaceuticals to prevent and treat several chronic diseases. In the present article, we review current knowledge about the bioactivities and health benefits of wild fruits, which is valuable for the exploitation and utilization of wild fruits.

Local Government and Traditional Authorities in Concert: Towards a More Productive Relationship

Directory of Open Access Journals (Sweden)

Callistus Mahama

2009-11-01

Full Text Available Ghana embarked on decentralisation in 1988 as a way of bringing decision making closer to the people. Since then, there have several reforms with a view to strengthening local governance. This article identifies a major challenge still facing Ghana’s decentralisation: Partnership between local government and traditional authorities. The paper discusses the fuzzy relationship between local governments and traditional authorities as a result of constitutional and legislative ambiguity on their relationship. Traditional Authorities perform important functions in the country, albeit their roles have waned since independence. Yet current legal provisions on local government have not sufficiently clarified their role in local administration. This has led to a murky and competing relationship between traditional authorities and local governments. In localities where mutual relationship exists, it is mainly as a result of the personalities involved and this has had a positive effect on the development of the area. The paper concludes by advocating for measures which among others include a re-enactment of legislation which will define the working relationship between traditional authorities and local government.

DNA from liver samples of 17 free-ranging wild Reeves' muntjac (Muntiacus reevesi) was used for PCR amplification of piropalsm 18S rRNA gene. Of 17 samples, 14 (82.4%) showed a specific PCR product which were cloned and sequenced. BLAST analysis of the sequences obtained showed similarities to Babesia sp., Theileria capreoli, Theileria uilenbergi and Theileria sp. BO302-SE. Phylogenetic analysis showed that the Babesia sp. detected in the present study was distantly separated from known Babesia species of wild and domestic animals. Six sequences showed 100% similarity to T. capreoli while five sequences were separated from all known Theileria species and constituted an independent clade with Theileria sp. BO302-SE derived from roe deer in Italy; two sequences were close to T. uilenbergi with 97% similarity. This is the first description of hemoparasite infection in free-ranging wild Reeves' muntjac in China. Our results indicate that wild Reeves' muntjac may play an important reservoir role for hemoparasites. Crown Copyright © 2014. Published by Elsevier Ireland Ltd. All rights reserved.

Besharat, Sima; Besharat, Mahsa; Jabbari, Ali

2009-01-01

Wild lettuce (Lactuca virosa) can cause toxic effects when eaten. Wild lettuce grows in the north of Iran and some natives consume it unaware of its adverse side effects. We describe eight patients with manifestations of wild lettuce toxicity, admitted to a general hospital affiliated to the Golestan University of Medical Sciences. All the patients recovered (although one had to spend 48 h in the intensive care unit) and no chronic complications were reported. A clinical suspicion of toxicity caused by wild lettuce intake and an accurate history formed the basis of the diagnosis. Conservative treatment, vital sign monitoring, control of patient intake and output, and reducing patient agitation provided the basis for treatment.

A wide array of wildlife species, including many animals, are used in traditional medicines across many medicinal systems, including in Traditional Chinese Medicine (TCM). Due to over-exploitation and habitat loss, the populations of many animals commonly used in TCM have declined and are unable to meet market demand. A number of measures have been taken to try to reduce the impact that this large and growing market for TCM may have on wild animal species. Consumer preferences and behavior are known to play an important role in the consumption and protection of wild animals used in traditional medicine, and thus are likely to be an important factor in the success of many of these mechanisms—particularly given the significant percentage of TCMs that are over-the-counter products (access to which is not mediated by practitioners). In this study we conducted questionnaires and designed stated preference experiments embodying different simulation scenarios using a random sample of the population in Beijing to elicit individuals’ knowledge, perceptions and preferences toward wild or farmed animal materials and their substitutes used in traditional Chinese medicine. We found that respondents had a stated preference for wild materials over farm-raised and other alternatives because they believe that the effectiveness of wild-sourced materials is more credible than that of other sources. However, we also found that, although respondents used TCM products, they had a poor understanding of the function or composition of either traditional Chinese medicines or proprietary Chinese medicines (PCM), and paid little attention to the composition of products when making purchasing decisions. Furthermore, awareness of the need for species protection, or “conservation consciousness” was found to play an important role in willingness to accept substitutions for wild animal materials, while traditional animal medicinal materials (TAMs) derived from well-known endangered species

Blood python (Python brongersmai Stull, 1938) is one of heavily exploited wildlife in Indonesia. The high demands on its skin trade have made its harvesting regulated under quota-based setting by the government to prevent over-harvesting. To gain understanding on the sustainability of P. brongersmai in the wild, biological characters of wild-caught specimens were studied. Samples were collected from two slaughterhouses from Rantau Prapat and Langkat. Parameters measured were morphological (Snout-vent length (SVL), body mass, abdomen width) and anatomical characters (Fat classes). Total samples of P. brongersmai in this research were 541 with 269 male and 272 female snakes. Female snakes had the highest proportion of individuals with the best quality of abdominal fat reserves (Class 3). Linear models are built and tested for its significance in relation between fat classes as anatomical characters and morphological characters. All tested morphological characters were significant in female snakes. By using linear equation models, we generate size limit to prioritize harvesting in the future. We suggest the use of SVL and stomach width ranging between 139,7 – 141,5 cm and 24,72 – 25,71 cm respectively to achieve sustainability of P. brongersmai in the wild.

In 1997, cutaneous papillomatosis caused by Florida manatee (Trichechus manatus latirostris [Tm]) papillomavirus 1 (TmPV1) was detected in seven captive manatees at the Homosassa Springs Wildlife State Park, Florida, USA, and, subsequently, in two wild manatees from the adjacent Homosassa River. Since then, papillomatosis has been reported in captive manatees housed in other locations, but not in wild animals. To determine TmPV1 antibody prevalence in captive and wild manatees sampled at various locations throughout Florida coastal regions, virus-like particles, composed of the L1 capsid protein of TmPV1, were generated with a baculovirus expression system and used to measure anti-TmPV1 antibodies in an enzyme-linked immunosorbent assay. Serologic analysis of 156 manatees revealed a TmPV1 antibody prevalence of 26.3%, with no significant difference between captive (n=39) and wild (n=117) manatees (28.2% and 25.6%, respectively). No antibody-positive wild animal showed PV-induced cutaneous lesions, whereas papillomatosis was observed in 72.7% of antibody-positive captive manatees. Our data indicate that Florida manatees living in the wild are naturally infected by TmPV1 but rarely show TmPV1-induced papillomatosis. Hence, it appears that the wild population would not be harmed in a case of contact with captive animals without visible lesions and productive infections, which could be thus released into the wild.

Wild food trees in Eastern Nuba Mountains, Sudan: Use diversity and threatening factors

Full Text Available This study was conducted in 2010 in Eastern Nuba Mountains, Sudan to investigate ethnobotanical food and non-food uses of 16 wild edible fruit producing trees. Quantitative and qualitative information was collected from 105 individuals distributed in 7 villages using a semi-structured questionnaire. Also gathering of data was done using a number of rapid rural appraisal techniques, including key informant interviews, group discussion, secondary data sources and direct observations. Data was analysed using fidelity level and informant consensus factor methods to reveal the cultural importance of species and use category. Utilizations for timber products were found of most community importance than food usages, especially during cultivated food abundance. Balanites aegyptiaca, Ziziphus spina-christi and Tamarindus indica fruits were asserted as most preferable over the others and of high marketability in most of the study sites. Harvesting for timber-based utilizations in addition to agricultural expansion and overgrazing were the principal threats to wild edible food producing trees in the area. The on and off prevailing armed conflict in the area make it crucial to conserve wild food trees which usually play a more significant role in securing food supply during emergency times, especially in times of famine and wars. Increasing the awareness of population on importance of wild food trees and securing alternative income sources, other than wood products, is necessary in any rural development programme aiming at securing food and sustaining its resources in the area.

Lack of government performance, among others due to the lack of coordination and communication among government agencies. Whilst, Enterprise Architecture (EA) in the government can be use as a strategic planning tool to improve productivity, efficiency, and effectivity. However, the existence components of Government Enterprise Architecture (GEA) do not show level of importance, that cause difficulty in implementing good e-government for good governance. This study is to explore the weight of GEA components using Principal Component Analysis (PCA) in order to discovered an inherent structure of e-government. The results show that IT governance component of GEA play a major role in the GEA. The rest of components that consist of e-government system, e-government regulation, e-government management, and application key operational, contributed more or less the same. Beside that GEA from other countries analyzes using comparative base on comon enterprise architecture component. These weighted components use to construct i-Government enterprise architecture. and show the relative importance of component in order to established priorities in developing e-government.

Hafezalkotob, Ashkan; Zamani, Soma

2018-05-01

In this paper, a bi-level game-theoretic model is proposed to investigate the effects of governmental financial intervention on green supply chain. This problem is formulated as a bi-level program for a green supply chain that produces various products with different environmental pollution levels. The problem is also regard uncertainties in market demand and sale price of raw materials and products. The model is further transformed into a single-level nonlinear programming problem by replacing the lower-level optimization problem with its Karush-Kuhn-Tucker optimality conditions. Genetic algorithm is applied as a solution methodology to solve nonlinear programming model. Finally, to investigate the validity of the proposed method, the computational results obtained through genetic algorithm are compared with global optimal solution attained by enumerative method. Analytical results indicate that the proposed GA offers better solutions in large size problems. Also, we conclude that financial intervention by government consists of green taxation and subsidization is an effective method to stabilize green supply chain members' performance.

Captive-rearing piping plovers: Developing techniques to augment wild populations

Science.gov (United States)

Powell, A.N.; Cuthbert, F.J.; Wemmer, L.C.; Doolittle, A.W.; Feirer, S.T.

1997-01-01

Techniques for captive-rearing and releasing piping plovers (Charadrius melodus) were developed using a surrogate species, killdeer (Charadrius vociferus). We compared captive-and parent-reared killdeer, and parent-reared piping plovers and determined that growth and behavior were similar. After surrogate trials determined that captive-rearing was feasible, we used the same methods to raise piping plover chicks from salvaged eggs. For captive-reared chick of both species, survival to fledging was higher than and behaviors similar to parent-reared chicks in the wild. Rearing techniques were fine-tuned, and ten piping plover fledglings were released to the wild. Based on our results, we developed recommendations for captive-rearing piping plovers using salvaged eggs to enhance productivity of small populations. ?? 1997 Wiley-Liss, Inc.

Does Arctic governance hold the key to achieving climate policy targets?

Science.gov (United States)

Forbis, Robert, Jr.; Hayhoe, Katharine

2018-02-01

Arctic feedbacks are increasingly viewed as the wild card in the climate system; but their most unpredictable and potentially dangerous aspect may lie in the human, rather than the physical, response to a warming climate. If Arctic policy is driven by agendas based on domestic resource development, the ensuing oil and gas extraction will ensure the failure of the Paris Agreement. If Arctic energy policy can be framed by the Arctic Council, however, its environmental agenda and fragmented governance structure offers the scientific community a fighting chance to determine the region’s energy future. Connecting Arctic climate science to resource economics via its unique governance structure is one of the most powerful ways the scientific community can protect the Arctic region’s environmental, cultural, and scientific resources, and influence international energy and climate policy.

Mannitol is a natural polyol with multiple industrial applications. In this work, mannitol production by Lactobacillus reuteri CRL 1101 was studied at free- and controlled-pH (6.0-4.8) fermentations using a simplified culture medium containing yeast and beef extracts and sugarcane molasses. The activity of mannitol 2-dehydrogenase (MDH), the enzyme responsible for mannitol synthesis, was determined. The effect of the initial biomass concentration was further studied. Mannitol production (41.5 ± 1.1 g/l), volumetric productivity (Q Mtl 1.73 ± 0.05 g/l h), and yield (Y Mtl 105 ± 11 %) were maximum at pH 5.0 after 24 h while the highest MDH activity (1.66 ± 0.09 U/mg protein) was obtained at pH 6.0. No correlation between mannitol production and MDH activity was observed when varying the culture pH. The increase (up to 2000-fold) in the initial biomass concentration did not improve mannitol formation after 24 h although a 2-fold higher amount was produced at 8 h using 1 or 2 g cell dry weight/l comparing to the control (0.001 g cell dry weight/l). Finally, mannitol isolation under optimum fermentation conditions was achieved. The mannitol production obtained in this study is the highest reported so far by a wild-type L. reuteri strain and, more interestingly, using a simplified culture medium.

Studies of wild animals' immunity often use comparison with laboratory-raised individuals. Using such an approach, various data were obtained concerning wild Norway rat's immunity. Lower or higher potential of immune system cells to respond to activation stimuli were shown, because of analysis of disparate parameters and/ or small number of analyzed individuals. Inconsistent differences between laboratory and wild rats were shown too, owing to great response variability in wild rats. We hypothesized that wild rats will express more intense immune activity compared to their laboratory counterparts which live in a less demanding environment. To test this, we analyzed the circulating levels of inflammatory cytokine interleukin-6 (IL-6), a mediator which has a central role in host immune defense. In addition, we examined the activity of the central immune organ, the spleen, including cell proliferation and production of pro-inflammatory cytokines interferon-γ (IFN-γ) and interleukin-17 (IL-17), which are major effectors of cellular adaptive immune response. In order to obtain reasonable insight into the immunity of wild Norway rats, analysis was conducted on a much larger number of individuals compared to other studies. Higher levels of plasma IL-6, higher spleen mass, cellularity and basal IFN-γ production concomitantly with lower basal production of anti-inflammatory cytokine interleukin-10 (IL-10) revealed more intense immune activity in the wild compared to laboratory rats. However, lower responsiveness of their spleen cells' proinflammatory cytokine production to concanavalin A (ConA) stimulation, along with preserved capacity of IL-10 response, might be perceived as an indication of wild rats' reduced capability to cope with incoming environmental stimuli, but also as a means to limit tissue damage. © 2017 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

Abscisic Acid Negatively Regulates Elicitor-Induced Synthesis of Capsidiol in Wild Tobacco1[W

Science.gov (United States)

Mialoundama, Alexis Samba; Heintz, Dimitri; Debayle, Delphine; Rahier, Alain; Camara, Bilal; Bouvier, Florence

2009-01-01

In the Solanaceae, biotic and abiotic elicitors induce de novo synthesis of sesquiterpenoid stress metabolites known as phytoalexins. Because plant hormones play critical roles in the induction of defense-responsive genes, we have explored the effect of abscisic acid (ABA) on the synthesis of capsidiol, the major wild tobacco (Nicotiana plumbaginifolia) sesquiterpenoid phytoalexin, using wild-type plants versus nonallelic mutants Npaba2 and Npaba1 that are deficient in ABA synthesis. Npaba2 and Npaba1 mutants exhibited a 2-fold higher synthesis of capsidiol than wild-type plants when elicited with either cellulase or arachidonic acid or when infected by Botrytis cinerea. The same trend was observed for the expression of the capsidiol biosynthetic genes 5-epi-aristolochene synthase and 5-epi-aristolochene hydroxylase. Treatment of wild-type plants with fluridone, an inhibitor of the upstream ABA pathway, recapitulated the behavior of Npaba2 and Npaba1 mutants, while the application of exogenous ABA reversed the enhanced synthesis of capsidiol in Npaba2 and Npaba1 mutants. Concomitant with the production of capsidiol, we observed the induction of ABA 8′-hydroxylase in elicited plants. In wild-type plants, the induction of ABA 8′-hydroxylase coincided with a decrease in ABA content and with the accumulation of ABA catabolic products such as phaseic acid and dihydrophaseic acid, suggesting a negative regulation exerted by ABA on capsidiol synthesis. Collectively, our data indicate that ABA is not required per se for the induction of capsidiol synthesis but is essentially implicated in a stress-response checkpoint to fine-tune the amplification of capsidiol synthesis in challenged plants.

Reflection on the role of the Dutch government in sustainable supply chains. New phase in the transition of sustainable products

International Nuclear Information System (INIS)

Vermeulen, W.; Kok, M.; Van Oorschot, M.

2011-01-01

This article is based on an exploratory study which analyses some of the earliest multi-actor sustainable supply chain governance systems in order to answer the key research questions: Which strategies and instruments do governments - national and supranational - apply in advancing sustainable production and consumption in global supply chains; and What is known about the effectiveness of these strategies and instruments? The study focuses on two supply chains with the longest history of addressing imports from developing countries (tropical timber and coffee). These two supply chains are compared with two supply chains that are gaining increasing attention: - cocoa and tea. The study shows that the two most 'mature' global sustainable supply chains are market led in issuing voluntary certification and that buying certified products is starting to become mainstream and increasingly effective. The sustainable supply chains for tea and cocoa are more recent developments but may develop faster because of the lessons learnt in sustainable supply chains developed earlier. [nl

Full Text Available Objectives : The aim of this study was to find optimal conditions for producing red ginseng from cultivated wild ginseng using the Turbo Mill. Methods : Characteristics of powdered cultivated wild ginseng based on various temperature settings of the Turbo Mill were observed, and changes in the content was measured by HPLC for various ginsenosides. Results : 1. The diameter of cultivated wild ginseng powder ground by the Turbo Mill was around 10㎛. 2. As the temperature rose, presusre, Specific Mechanical Energy(SME, and density decreased, whileas Water Solubility Index(WSI increased. 3. As the temperature rose, super fine powder showed tendency to turn into dark brown. 4. Measuring content changes by HPLC, there was no detection of ginsenoside Rg3 and ginsenosideRg1, Rb1, and Rh2 concentrations decreased with increase in temperature. Conclusions : Super fine powder of cultivated wild ginseng produced by the Turbo Mill promotes easy absorption of effective ingredients by breaking the cell walls. Using this mechanism to produce red ginseng from cultivated wild ginseng, it yielded less than satisfactory results under the current experiment setup. Furtherresearches are needed to verify more suitable condition for the production of red ginseng.

Australian wild rice reveals pre-domestication origin of polymorphism deserts in rice genome.

Krishnan S, Gopala; Waters, Daniel L E; Henry, Robert J

Rice is a major source of human food with a predominantly Asian production base. Domestication involved selection of traits that are desirable for agriculture and to human consumers. Wild relatives of crop plants are a source of useful variation which is of immense value for crop improvement. Australian wild rices have been isolated from the impacts of domestication in Asia and represents a source of novel diversity for global rice improvement. Oryza rufipogon is a perennial wild progenitor of cultivated rice. Oryza meridionalis is a related annual species in Australia. We have examined the sequence of the genomes of AA genome wild rices from Australia that are close relatives of cultivated rice through whole genome re-sequencing. Assembly of the resequencing data to the O. sativa ssp. japonica cv. Nipponbare shows that Australian wild rices possess 2.5 times more single nucleotide polymorphisms than in the Asian wild rice and cultivated O. sativa ssp. indica. Analysis of the genome of domesticated rice reveals regions of low diversity that show very little variation (polymorphism deserts). Both the perennial and annual wild rice from Australia show a high degree of conservation of sequence with that found in cultivated rice in the same 4.58 Mbp region on chromosome 5, which suggests that some of the 'polymorphism deserts' in this and other parts of the rice genome may have originated prior to domestication due to natural selection. Analysis of genes in the 'polymorphism deserts' indicates that this selection may have been due to biotic or abiotic stress in the environment of early rice relatives. Despite having closely related sequences in these genome regions, the Australian wild populations represent an invaluable source of diversity supporting rice food security.

Crop to wild gene flow: Does more sophisticated research provide better risk assessment?

International Nuclear Information System (INIS)

Jong, Tom J. de; Rong, Jun

2013-01-01

Highlights: ► Genes can sometimes flow from genetically modified crops to wild plants. ► The probability can be predicted from seed production of hybrids and backcrosses. ► Nevertheless predictions about introgression remain uncertain. ► One should be reluctant to ask too much detail in Environmental Risk Assessment. ► Instead possible harm should have a more central place. -- Abstract: Research into introgression, the permanent incorporation of alleles of one species into another, is flourishing and gives new insights into evolution and speciation. The possible transfer of transgenes from crop species to wild relatives is of major concern for regulators. Applicants that want to introduce a genetically modified (GM) crop on the European market need to indicate the likelihood of introgression and its anticipated effects in an Environmental Risk Analysis (ERA). The European Food Safety Association (EFSA) and competent authorities of different countries evaluate the ERA. Predicting which crop alleles will or will not be permanently incorporated into wild populations requires, apart from information on seed production of hybrids, information on how these crop alleles are associated with fitness. Advances in genetics open new avenues to address this question in more detail. We argue, however, that, even with the best techniques, predicting introgression from crop to wild species will always have a considerable margin of uncertainty. One must therefore be prudent to demand more detailed research for the ERA, especially since the possible harm of transgenes in natural populations remains so poorly defined by regulators

Wild-type lactobacillus isolated form Khorisa, a fermented bamboo shoot product of Assam, India were evaluated for production anti-bacterial secondary biometabolites, against Staphylococcus aureus. Submerged fermentation technique was used for the production of secondary anti-microbial biometabolite by a single wild-type lactobacillus strain, which tested positive for the release of anti-bacterial factor(s). Crude cell-free supernatant was obtained, followed by extraction in water-immiscible solvents viz., chloroform, hexane, petroleum ether. Chloroform extract of cell-free crude supernatant showed maximum yield (0.054 g/ml) and inhibited all indicator bacterial strains viz., Escherichia coli, Staphylococcus aureus, and Bacillus cereus. Yields of hexane and petroleum ether extract were 0.052 and 0.026 g/ml, respectively. Minimum lethal dose concentration assay of the chloroform extract showed LDmin values at 27, 1.68, and 1.68 mg/ml for E. coli, S. aureus, and B. cereus, respectively. Kill time for all the indicator bacterial strains were less than 12 h. The efficacy of the anti-bacterial substance seemed to depend on the presence of organic acids, particularly lactic acid. Conceptual-based suggestion for the development of an onsite secondary metabolites recovery system during continuous fermentation has also been attempted.

Roles of Governments in Multi-Actor Sustainable Supply Chain. Governance Systems and the effectiveness of their interventions. An exploratory study

During the last decade, a growing number of market-based certification systems has been introduced for sustainable products consumed in the Netherlands and the EU but sourced through international supply chains. These systems, which cover agro-food products as well as non-food products, consist of requirements for products from developing countries with regard to environmental and social-ethical issues. These systems aim to improve production processes at the front end of the supply chain. These so called 'sustainable supply chain systems' have been initiated and are managed mainly by the market and civil society, without directly involving the government. This raises questions about the effectiveness, transparency, and legitimacy of such forms of self-regulation and about the most appropriate role for national government in relation to these emerging systems. This exploratory study analyses some of the earliest multi-actor sustainable supply chain governance systems in order to answer the key research questions: Which strategies and instruments do governments - national and supranational - apply in advancing sustainable production and consumption in global supply chains; and What is known about the effectiveness of these strategies and instruments? The study focuses on two supply chains with the longest history of addressing imports from developing countries (tropical timber and coffee). These two supply chains are compared with two supply chains that are gaining increasing attention: cocoa and tea. This study shows that the two most 'mature' global sustainable supply chains are market led in issuing voluntary certification and that buying certified products is starting to become mainstream and increasingly effective. The sustainable supply chains for tea and cacoa are more recent developments but may develop faster because of the lessons learnt in sustainable supply chains developed earlier.

Drought Tolerance in Modern and Wild Wheat

2013-01-01

The genus Triticum includes bread (Triticum aestivum) and durum wheat (Triticum durum) and constitutes a major source for human food consumption. Drought is currently the leading threat on world's food supply, limiting crop yield, and is complicated since drought tolerance is a quantitative trait with a complex phenotype affected by the plant's developmental stage. Drought tolerance is crucial to stabilize and increase food production since domestication has limited the genetic diversity of crops including wild wheat, leading to cultivated species, adapted to artificial environments, and lost tolerance to drought stress. Improvement for drought tolerance can be achieved by the introduction of drought-grelated genes and QTLs to modern wheat cultivars. Therefore, identification of candidate molecules or loci involved in drought tolerance is necessary, which is undertaken by “omics” studies and QTL mapping. In this sense, wild counterparts of modern varieties, specifically wild emmer wheat (T. dicoccoides), which are highly tolerant to drought, hold a great potential. Prior to their introgression to modern wheat cultivars, drought related candidate genes are first characterized at the molecular level, and their function is confirmed via transgenic studies. After integration of the tolerance loci, specific environment targeted field trials are performed coupled with extensive analysis of morphological and physiological characteristics of developed cultivars, to assess their performance under drought conditions and their possible contributions to yield in certain regions. This paper focuses on recent advances on drought related gene/QTL identification, studies on drought related molecular pathways, and current efforts on improvement of wheat cultivars for drought tolerance.

Laboratory and wild-derived mice with multiple loci for production of xenotropic murine leukemia virus.

Science.gov (United States)

Kozak, C A; Hartley, J W; Morse, H C

1984-07-01

Mendelian segregation analysis was used to define genetic loci for the induction of infectious xenotropic murine leukemia virus in several laboratory and wild-derived mice. MA/My mice contain two loci for xenotropic virus inducibility, one of which, Bxv -1, is the only induction locus carried by five other inbred strains. The second, novel MA/My locus, designated Mxv -1, is unlinked to Bxv -1 and shows a lower efficiency of virus induction. The NZB mouse carries two induction loci; both are distinct from Bxv -1 since neither is linked to the Pep-3 locus on chromosome 1. Finally, one partially inbred strain derived from the wild Japanese mouse, Mus musculus molossinus, carries multiple (at least three) unlinked loci for induction of xenotropic virus. Although it is probable that inbred strains inherited xenotropic virus inducibility from Japanese mice, our data suggest that none of the induction loci carried by this particular M. m. molossinus strain are allelic with Bxv -1.

Wild food plants of Remote Oceania

Directory of Open Access Journals (Sweden)

Will C. McClatchey

2012-11-01

Full Text Available Agricultural societies partly depend upon wild foods. Relationships between an agricultural society and its wild foods can be explored by examining how the society responds through colonization of new lands that have not been previously inhabited. The oldest clear example of this phenomenon took place about 5000 years ago in the tropical Western Pacific at the “boundary” interface between Near and Remote Oceania. An inventory of wild and domesticated food plants used by people living along “the remote side of ” that interface has been prepared from the literature. This was then assessed for the roles of plants at the time of original colonization of Remote Oceania. The majority of species are wild foods, and most of these are used as leafy vegetables and fruits. The wild food plants mostly serve as supplements to domesticated species, although there are a few that can be used as substitutes for traditional staples.

Oscar Wilde and the brain cell.

Science.gov (United States)

Cohn, Elisha

2013-01-01

This chapter considers Oscar Wilde's interest in the brain cell as an aesthetic object. Offering an account of Wilde's career that analyzes his early interest in physiology and philosophy, this chapter argues that Wilde's uniquely aesthetic take on the brain suggests that he rejects an account of the self as autonomous or self-determining. For many late Victorians brain science threatened both the freedom of human action and the legitimacy of beauty because it had the potential to invalidate conscious experience. But writers whose work Wilde knew, like John Ruskin, W. K. Clifford, and John Tyndall, avoided the despair of materialism by using aesthetic terms in their own discussions of life's invisible materials. Wilde's art collaborates with the contemporary sciences. His depictions of the cell direct the senses to a new field of being that emphasizes the molecular life all humans have in common, in which individual responsibility and activity matter less than the necessity of beauty. © 2013 Elsevier B.V.

2017-02-01

Full Text Available Little is known about genetic variation of seed related traits and their association with forage characters in sainfoin. In order to investigate the variation and relationship among seed yield and its components, 93 genotypes from 21 wild and cultivated species of genus Onobrychis were evaluated using a randomized complete block design with four replications at Isfahan University of Technology Research Farm, Isfahan, Iran. Analysis of variance showed that there was significant difference among genotypes, indicating existence of considerable genetic variation in this germplasm. Panicle fertility and panicle length had the most variation in cultivated and the wild genotypes, respectively. Results of correlation analysis showed that seed yield was positively correlated with number of stems per plant and number of seeds per panicle and negatively correlated with panicle length and days to 50% flowering. Seed yield had positive correlation with forage yield in wild species while this correlation was not significant in cultivated one. Cluster analysis classified the genotypes into three groups which separate wild and cultivated species. Based on principal component analysis the first component was related to seed yield and the second one was related to components of forage yield which can be used for selection of high forage and seed yielding genotypes.

The Governance of Multi-Use Platforms at Sea for Energy Production and Aquaculture: Challenges for Policy Makers in European Seas

2016-04-01

Full Text Available European seas are encountering an upsurge in competing marine activities and infrastructures. Traditional exploitation such as fisheries, tourism, transportation, and oil production are accompanied by new sustainable economic activities such as offshore windfarms, aquaculture, and tidal and wave energy. One proposed solution to overcome possible competing claims at sea lies in combining these economic activities as part of Multi-Use Platforms at Sea (MUPS. MUPS can be understood as areas at sea, designated for a combination of activities, either completely integrated in a platform or in shared marine space. MUPS can potentially benefit from each other in terms of infrastructure, maintenance, etc. Developing MUPS in the marine environment demands adequate governance. In this article, we investigate four European sites to find out how governance arrangements may facilitate or complicate MUPs. In particular, we apply a framework specifying policy, economic, social, technical, environmental, and legal (PESTEL factors to explore governance arrangements in four case study sites in different sea basins around Europe (the Mediterranean Sea, the Atlantic Ocean, the North Sea, and the Baltic Sea. The article concludes with policy recommendations on a governance regime for facilitating the development of MUPS in the future.

Wild bees are highly valuable pollinators. Along with managed honey bees, they provide a critical ecosystem service by ensuring stable pollination to agriculture and wild plant communities. Increasing concern about the welfare of both wild and managed pollinators, however, has prompted recent calls for national evaluation and action. Here, for the first time to our knowledge, we assess the status and trends of wild bees and their potential impacts on pollination services across the coterminous United States. We use a spatial habitat model, national land-cover data, and carefully quantified expert knowledge to estimate wild bee abundance and associated uncertainty. Between 2008 and 2013, modeled bee abundance declined across 23% of US land area. This decline was generally associated with conversion of natural habitats to row crops. We identify 139 counties where low bee abundances correspond to large areas of pollinator-dependent crops. These areas of mismatch between supply (wild bee abundance) and demand (cultivated area) for pollination comprise 39% of the pollinator-dependent crop area in the United States. Further, we find that the crops most highly dependent on pollinators tend to experience more severe mismatches between declining supply and increasing demand. These trends, should they continue, may increase costs for US farmers and may even destabilize crop production over time. National assessments such as this can help focus both scientific and political efforts to understand and sustain wild bees. As new information becomes available, repeated assessments can update findings, revise priorities, and track progress toward sustainable management of our nation's pollinators.

[The political project and governance capacities].

Spinelli, Hugo

2012-01-01

This article presents a theoretical overview of personal and institutional governance capacities (experience, leadership and knowledge on the individual level, and organizational capital available on the institutional level) and their relationship to politics and policies in the Latin American context. Using the theoretical production of Carlos Matus regarding the act of governing, diverse dimensions of this problem are put into discussion in relation to other authors and experiences in different historical moments. Theories, methods and techniques of government are explored and the need for state reform with an internal logic is analyzed. It is concluded that there is a need to build a theory for the practice of governing/managing public organizations, and this construction requires creative actions that use theory as a toolbox.

Wild reindeer Rangifer tarandus (L. in Chukotka

Full Text Available We reviewed historical records of the abundance and distribution of wild reindeer {Rangifer tarandus L. in Chukotka and studied reindeer numbers, distribution and behavior from 1983 to 1993. There were large numbers of wild reindeer in Chukotka until the end of the eighteenth century, but during the nineteenth century the population declined probably from intensive harvest after the introduction of firearms by the Cossacks. During the nineteenth century herding of domestic reindeer also increased, and reindeer herders continued to hunt wild reindeer intensively. During the 1950s there were only about 8500 wild reindeer in two separate herds in Chukotka. By the late 1970s the wild reindeer population had increased to about 11 000. Ten years later we estimated 16 534 reindeer, and found only one contiguous population. Presently, the population calves and spends the summer in the Anadyr Uplands and migrates west and southwest to spend the winter in forest tundra and northern taiga regions. Predators, primarily wolves and brown bears, kill a significant number of calves. Today, the wild reindeer in Chukotka coexist with 300 000 domestic reindeer. However, current costs of gasoline and helicopters make it prohibitive to herd reindeer in much of central Chukotka, so that wild reindeer have room for expansion. Poaching is a major conservation problem. Poachers shoot wild reindeer from helicopters to obtain velvet antlers. Leaders of domestic reindeer cooperatives encourage poaching by telling people that wild reindeer are in fact just stray domestic reindeer and there is no enforcement of game laws.

Full Text Available Generally bark has a negative effect pulp and paper properties. In this study, paper pulp and hand sheets were produced from Wild dogwood (Cornus australis L. using Kraft method. The cooking have been different conditions, chip / solution ratio 1/5, cooking temperature 170±2 °C by taking constant. Kraft method with the Na2S/NaOH, 18/20, 18/15, 18/10, 18/5 performed. Samples were used with and without bark in order to identify the negative impacts of the bark on pulp and paper production. In addition, it has been investigated whether the time of reaching the maximum temperature of K2 cooking is reduced from 120 minutes to 90 minutes, and the time and energy saving can be made. For all of the mechanical properties that were measured and pulp yield, the bark had a negative effect. But, this effect had not significant on mechanical properties at 95% significant level. On the other hand the bark had a negative effect on brightness and positive effects on opacity. These effects had significant at 95% significant level.

The Role of Governance in Agricultural Expansion and Intensification: a Global Study of Arable Agriculture

Directory of Open Access Journals (Sweden)

Menno Mandemaker

2011-06-01

Full Text Available In this research we studied empirical relationships between agricultural production dynamics and six quantitative World Bank governance indicators for 173 countries between 1975 and 2007. It is hypothesized that in countries with lower quality of governance, agricultural production increases are more likely to be achieved by area expansions than by increases in yields. We distinguished four groups of countries: those with both area and yield increases; those with increasing yields but decreasing area; those with decreasing yields but a growing area; and those with both declines in yields and area. We analyzed differences between these four groups, and also analyzed governance-production relationships within these groups. On average, quality of governance is low in countries with both area and yield increases and high in countries with increasing yields but decreasing area. Countries with declining yields were too few in number to allow for quantitative analyses. The analysis of governance-production relationships within the four groups suggests that countries with a lower quality of governance are more inclined to achieve production increases by expanding agricultural area rather than increasing yields. Additional explanatory value of governance indicators to agricultural production dynamics is generally small, but nevertheless significant in most cases. Our results suggest that, in order for agricultural production to increase without excessive expansions of agricultural area, governance issues should be resolved.

Graduated Sovereignty and Global Governance Gaps: Special Economic Zones and the Illicit Trade In Tobacco Products.

Science.gov (United States)

Holden, Chris

2017-07-01

Illicit trade in tobacco products has been a significant problem globally for many years. It allows cigarettes to be sold far below their legal price and thus contributes to higher consumption, morbidity and mortality, and deprives state treasuries of a substantial amount of revenue. This article identifies special economic zones (SEZs), particularly free trade zones, as a key conduit for this illicit trade. The development of SEZs as weak points in the global governance architecture is explained with reference to the concept of 'graduated sovereignty', whereby the uniform management of territory by modern states has given way to a more spatially selective form of territorial governance, in which some slices of territory are more fully integrated into the world economy than others via various forms of differential regulation. Attempts to comprehensively (re)regulate SEZs, in the face of growing evidence of the dysfunctionalities that they can engender, have so far been unsuccessful. It is concluded that the neo-liberal global economy has facilitated a regulatory 'race to the bottom', a problem that can only ultimately be overcome by international negotiation and agreement.

Immunity induced by DNA vaccines containing the hemagglutinin (H) and nucleoprotein (N) genes of wild-type and attenuated canine distemper virus (CDV) was investigated in mink (Mustela vison), a highly susceptible natural host of CDV. All DNA-immunized mink seroconverted, and significant levels of virus-neutralizing (VN) antibodies were present on the day of challenge with wild-type CDV. The DNA vaccines also primed the cell-mediated memory responses, as indicated by an early increase in the number of interferon-gamma (IFN-γ)-producing lymphocytes after challenge. Importantly, the wild-type and attenuated CDV DNA vaccines had a long-term protective effect against wild-type CDV challenge. The vaccine-induced immunity induced by the H and N genes from wild-type CDV and those from attenuated CDV was comparable. Because these two DNA vaccines were shown to protect equally well against wild-type virus challenge, it is suggested that the genetic/antigenic heterogeneity between vaccine strains and contemporary wild-type strains are unlikely to cause vaccine failure.

Evaluation of Wild Lentil Species as Genetic Resources to Improve Drought Tolerance in Cultivated Lentil

Directory of Open Access Journals (Sweden)

Linda Y. Gorim

2017-06-01

Full Text Available Increasingly unpredictable annual rainfall amounts and distribution patterns have far reaching implications for pulse crop biology. Seedling and whole plant survival will be affected given that water is a key factor in plant photosynthesis and also influences the evolving disease spectrum that affects crops. The wild relatives of cultivated lentil are native to drought prone areas, making them good candidates for the evaluation of drought tolerance traits. We evaluated root and shoot traits of genotypes of cultivated lentil and five wild species grown under two water deficit regimes as well as fully watered conditions over a 13 week period indoors. Plants were grown in sectioned polyvinyl chloride (PVC tubes containing field soil from the A, B, and C horizons. We found that root distribution into different soil horizons varied among wild lentil genotypes. Secondly, wild lentil genotypes employed diverse strategies such as delayed flowering, reduced transpiration rates, reduced plant height, and deep root systems to either escape, evade or tolerate drought conditions. In some cases, more than one drought strategy was observed within the same genotype. Sequence based classification of wild and cultivated genotypes did not explain patterns of drought response. The environmental conditions at their centers of origin may explain the patterns of drought strategies observed in wild lentils. The production of numerous small seeds by wild lentil genotypes may have implications for yield improvement in lentil breeding programs.

We examine the impact of governance mode and governance fit on performance in make-or-ally decisions. We argue that while horizontal collaboration and autonomous governance have direct and countervailing performance implications, the alignment of make-or-ally choices with the focal firm's resource endowment and the activity's resource requirements leads to better performance. Data on the aircraft industry show that relative to aircraft developed autonomously, collaborative aircraft exhibit gr...

Study on the potential imports by member states of agricultural products containing radiocesium concentrations in excess of EC limits

International Nuclear Information System (INIS)

Weiss, D.; Feige, S.

2013-01-01

As a consequence of the Chernobyl accident, the European Commission maintains Council Regulation (EEC) number 737/90 which sets out the conditions governing the import of agricultural products originating in third countries and includes maximum permitted level (MPL) that shall be applied in respect of contamination with radiocesium. The main objective of the study was to identify agricultural products which might exceed the MPL of radiocesium. The results show that mushroom and berries from Norway or Russia or Belarus or Ukraine may exceed the MPL. Reindeer meat from Norway will stay suspicious for at least 30 years as well as meat from wild animals originating from Russia, Belarus and Ukraine and some other countries. Some agricultural products like living cows or horses, poultry,... can be excluded from the list except for products issued from areas with strong contamination

The present study aims the identification and quantification of trace elements in two types of honey samples: Orchard honey and Wild honey from mainland Portugal. Chemical elements content was assessed by Instrumental Neutron Activation Analysis (INAA). Concentrations were determinated for Ag, As, Br, Ca, Cl, Cs, Cu, Fe, K, La, Mg, Mn, Na, Rb, Sb, Sc, U, V and Zn. The nutritional values of both honey types were evaluated since this product contains some elements that are essential dietary nutrients for humans. Physical properties of the honey samples, such as electrical conductivy and pH, were assessed as well.

Physiological and molecular characterization of Si uptake in wild rice species.

Cultivated rice (Oryza sativa) accumulates high concentration of silicon (Si), which is required for its high and sustainable production. High Si accumulation in cultivated rice is achieved by a high expression of both influx (Lsi1) and efflux (Lsi2) Si transporters in roots. Herein, we physiologically investigated Si uptake, isolated and functionally characterized Si transporters in six wild rice species with different genome types. Si uptake by the roots was lower in Oryza rufipogon, Oryza barthii (AA genome), Oryza australiensis (EE genome) and Oryza punctata (BB genome), but similar in Oryza glumaepatula and Oryza meridionalis (AA genome) compared with the cultivated rice (cv. Nipponbare). However, all wild rice species and the cultivated rice showed similar concentration of Si in the shoots when grown in a field. All species with AA genome showed the same amino acid sequence of both Lsi1 and Lsi2 as O. sativa, whereas species with EE and BB genome showed several nucleotide differences in both Lsi1 and Lsi2. However, proteins encoded by these genes also showed transport activity for Si in Xenopus oocyte. The mRNA expression of Lsi1 in all wild rice species was lower than that in the cultivated rice, whereas the expression of Lsi2 was lower in O. rufipogon and O. barthii but similar in other species. Similar cellular localization of Lsi1 and Lsi2 was observed in all wild rice as the cultivated rice. These results indicate that superior Si uptake, the important trait for rice growth, is basically conserved in wild and cultivated rice species. © 2013 Scandinavian Plant Physiology Society.

Livestock food systems play key subsistence and income generation roles in low to middle income countries and are important networks for zoonotic disease transmission. The aim of this study was to use a value chain framework to characterize the broiler chicken meat system of Nairobi, its governance and sanitary risks. A total of 4 focus groups and 8 key informant interviews were used to collect cross-sectional data from: small-scale broiler farmers in selected Nairobi peri-urban and informal settlement areas; medium to large integrated broiler production companies; traders and meat inspectors in live chicken and chicken meat markets in Nairobi. Qualitative data were collected on types of people operating in the system, their interactions, sanitary measures in place, sourcing and selling of broiler chickens and products. Framework analysis was used to identify governance themes and risky sanitary practices present in the system. One large company was identified to supply 60% of Nairobi's day-old chicks to farmers, mainly through agrovet shops. Broiler meat products from integrated companies were sold in high-end retailers whereas their low value products were channelled through independent traders to consumers in informal settlements. Peri-urban small-scale farmers reported to slaughter the broilers on the farm and to sell carcasses to retailers (hotels and butcheries mainly) through brokers (80%), while farmers in the informal settlement reported to sell their broilers live to retailers (butcheries, hotels and hawkers mainly) directly. Broiler heads and legs were sold in informal settlements via roadside vendors. Sanitary risks identified were related to lack of biosecurity, cold chain and access to water, poor hygiene practices, lack of inspection at farm slaughter and limited health inspection in markets.
 Large companies dominated the governance of the broiler system through the control of day-old chick production. Overall government control was described as

1997-01-01

This talk is the second in an expanded series of presentations on the Government-Industry-University and Research Laboratories Coordination for new product development, which is a timely and important public policy issue. Such interactions have become particularly timely in light of the present decline in funding for research and development (R ampersand D) in the nation''s budget and in the private sector. These interactions, at least in principle, provide a means to maximize benefits for the greater good of the nation by pooling the diminishing resources. National laboratories, which traditionally interacted closely with the universities in educational training, now are able to also participate closely with industry in joint R ampersand D thanks to a number of public laws legislated since the early 80s. A review of the experiences with such interactions at Argonne National Laboratory, which exemplifies the national laboratories, shows that, despite differences in their traditions and the missions, the national laboratory-industry-university triangle can work together

Full Text Available Assessing the achievement of Indonesian government institutions in implementing e-government has been conducted since around a decade ago. Several national assessments are available with almost the same ranking results. There is an agreement that the ultimate goal of e-government implementation is to achieve good government governance (GGG, while success stories of e-government require good governance practices. This study explored the correlation between e-government achievement and GGG achievement in Indonesia. Spearman’s rank correlation was used to characterize the relationship strength between e-government assessment results and good governance assessment results. The data were collected from institutions that participated in e-government and good governance assessments. The results showed that the correlation between these two entities is not very strong. Most cases showed that e-government implementation and the achievement of good governance have only a moderate positive correlation and none of the studied cases indicated a significant connection. This result can be attributed to the lack of emphasis on goals achievement in the assessments. Thus, it is recommended that future Indonesian e-government assessments should involve impact indicators.

Factors governing particulate corrosion product adhesion to surfaces in water reactor coolant circuits

International Nuclear Information System (INIS)

1979-03-01

Gravity, van der Waals, magnetic, electrical double layer and hydrodynamic forces are considered as potential contributors to the adhesion of particulate corrosion products to surfaces in water reactor coolant circuits. These forces are renewed and evaluated, and the following are amongst the conclusions drawn; adequate theories are available to estimate the forces governing corrosion product particle adhesion to surfaces in single phase flow in water reactor coolant circuits. Some uncertainty is introduced by the geometry of real particle-surface systems. The major uncertainties are due to inadequate data on the Hamaker constant and the zeta potential for the relevant materials, water chemistry and radiation chemistry at 300 0 C; van der Waals force is dominant over the effect of gravity for particles smaller than about 100 m; quite modest zeta potentials, approximately 50mV, are capable of inhibiting particle deposition throughout the size range relevant to water reactors; for surfaces exposed to typical water reactor flow conditions, particles smaller than approximately 1 m will be stable against resuspension in the absence of electrical double layer repulsion; and the magnitude of the electrical double layer repulsion for a given potential depends on whether the interaction is assumed to occur at constant potential or constant change.

Harnessing Genetic Diversity of Wild Gene Pools to Enhance Wheat Crop Production and Sustainability: Challenges and Opportunities

Directory of Open Access Journals (Sweden)

Carla Ceoloni

2017-12-01

Full Text Available Wild species are extremely rich resources of useful genes not available in the cultivated gene pool. For species providing staple food to mankind, such as the cultivated Triticum species, including hexaploid bread wheat (Triticum aestivum, 6x and tetraploid durum wheat (T. durum, 4x, widening the genetic base is a priority and primary target to cope with the many challenges that the crop has to face. These include recent climate changes, as well as actual and projected demographic growth, contrasting with reduction of arable land and water reserves. All of these environmental and societal modifications pose major constraints to the required production increase in the wheat crop. A sustainable approach to address this task implies resorting to non-conventional breeding strategies, such as “chromosome engineering”. This is based on cytogenetic methodologies, which ultimately allow for the incorporation into wheat chromosomes of targeted, and ideally small, chromosomal segments from the genome of wild relatives, containing the gene(s of interest. Chromosome engineering has been successfully applied to introduce into wheat genes/QTL for resistance to biotic and abiotic stresses, quality attributes, and even yield-related traits. In recent years, a substantial upsurge in effective alien gene exploitation for wheat improvement has come from modern technologies, including use of molecular markers, molecular cytogenetic techniques, and sequencing, which have greatly expanded our knowledge and ability to finely manipulate wheat and alien genomes. Examples will be provided of various types of stable introgressions, including pyramiding of different alien genes/QTL, into the background of bread and durum wheat genotypes, representing valuable materials for both species to respond to the needed novelty in current and future breeding programs. Challenging contexts, such as that inherent to the 4x nature of durum wheat when compared to 6x bread wheat, or

Full Text Available Crop growth models could stimulate growth and development based on science principles and mathematical equations. They also able to evaluate effects of climate, soil, water and agronomic management practices on crop yield. In the present study, an eco-physiological simulation model developed to assess wild oat damage to winter wheat growth and yield. The general structure of this model is derived from LINTUL1 model which modified to wild oat competition against winter wheat. LINTUL1 model was developed for simulation of spring wheat potential production level. In this study, first, we added development stage (DVS and vernalization to LINTUL1 for simulation of winter wheat growth and development and then the model calibrated for potential production level. Finally, we incorporate harmful effects of wild oat to winter wheat growth and yield. Weather data used as input were average daily minimum and maximum temperature (°C and daily global radiation (MJ m-2 in Mashhad, Iran. Parameter values were derived from the literature. The model is written in Fortran Simulation Translator (FST programming language and then validated based on an experiment data. For these purposes different wild oat plant densities were arranged. The data of this experiment does not use for calibration. The results showed that this model was in general able to simulate the temporal changes in DVS of winter wheat and wild oat, total dry matter (TDM of winter wheat and wild oat and yield loss of wheat due to wild oat competition in all treatments, satisfactorily. Root mean square error (RMSE for winter wheat DVS, wild oat DVS, average winter wheat TDM, average wild oat TDM, and yield loss of winter wheat was 10.4, 14.5, 5.8, 7.6 and 7.5, respectively.

Genetic differences in growth, migration, and survival between hatchery and wild steelhead and Chinook salmon: Introduction and executive summary

Science.gov (United States)

Rubin, Steve P.; Reisenbichler, Reginald; Wetzel, Lisa A.; Hayes, Michael C.

2012-01-01

This report presents results of studies testing for genetically based differences in performance (growth, migration, and survival) between hatchery and wild populations of steelhead and Chinook salmon (Project Number 90-052). The report is organized into 10 chapters with a general study introduction preceding the first chapter. A growing body of data shows that domestication and a resulting loss of fitness for natural rearing occur in hatchery populations of anadromous salmonids; however, the magnitude of domestication will vary among species and hatchery programs. Better information on domestication is needed to accurately predict the consequences when hatchery and wild fish interbreed. The intent of hatchery supplementation is to increase natural production through introduction of hatchery fish into natural production areas. The goal of this study was to provide managers with information on the genetic risks of hatchery supplementation to wild populations of Columbia River Basin summer steelhead and spring Chinook salmon.

WildSense: Monitoring Interactions among Wild Deer in Harsh Outdoor Environments Using a Delay-Tolerant WSN

Directory of Open Access Journals (Sweden)

Junho Ahn

2016-01-01

Full Text Available Biologists and ecologists often monitor the spread of disease among deer in the wild by using tracking systems that record their movement patterns, locations, and interaction behavior. The existing commercial systems for monitoring wild deer utilize collars with GPS sensors, deployed on captured and rereleased deer. The GPS sensors record location data every few hours, enabling researchers to approximate the interaction behavior of tracked deer with their GPS locations. However, the coarse granularity of periodically recorded GPS location data provides only limited precision for determining deer interaction behavior. We have designed a novel system to monitor wild deer interaction behavior more precisely in harsh wilderness environments. Our system combines the functionalities of both GPS and RF-radio sensors with low-cost and minimal-resource motes. We designed and built our system to be able to operate robustly for a period of up to several months for continual tracking and monitoring of the locations and interaction behaviors of wild deer in harsh environments. We successfully deployed six deer collars on six wild deer that were captured and rereleased in the Soapstone Prairie Natural Area of northern Colorado over a one-month period. In this paper, we describe how we designed and built this system and evaluate its successful operation in a wilderness area.

Hybridization study of wild rice Oryza glumaepatula with varieties of cultivated rice (O. sativa) and wild (O. grandiglumis)

Villalobos Cascante, Eddier

2015-01-01

The process of interspecific hybridization of the wild species O. glumaepatula is studied with commercial varieties of the species O. sativa and O. grandiglumis, by morphological evaluation and hybrid flow cytometry. Hybrid plants were evaluated of cross between O. glumaepatula, located in the wetlands of Rio Medio Queso and two varieties of O. sativa, Puita Inta and CFX 18 resistant to a herbicide. The technique of Polymerase Chain Reaction Allele Specifies Oligonucleotide (PCR-ASO) was used to detect allelic mutations in the ALS gene conferring herbicide resistance, and it is confirmed the hybrid nature of the plants obtained at crossings. 68 hybrids were obtained: O. glumaepatula x P. Inta, 21 hybrids P. Inta x O. glumaepatula, 4 hybrids O. glumaepatula x CFX-18 and 15 hybrids CFX-18 x O. glumaepatula. 10 morphological descriptors of the genus Oryza were evaluated and determined that are indifferent to the direction and type of crossing, the hybrids resemble to the wild species O. glumaepatula for characters: height, panicle length and ligule length. All hybrids have showed similarity to commercial varieties in flag leaf length. Other characters evaluated in the hybrids have presented maternal effect, heterosis and intermediate values. The protocol of flow cytometry (FCM) is standardized species for Oryza genus analyzing nuclear DNA content of 106 samples of leaf tissue of wild species O. glumaepatula, O. grandiglumis; whose average has been of 0.73 picograms, and natural hybrids product of the cross of these species. The result has been intermediate compared with O. grandiglumis and O. glumaepatula that have made available to 1.0 picograms and 0.50 of DNA respectively. The molecular nature of the hybrids was confirmed in this way. (author) [es

Deriving inflation forecasts from government bond prices

Directory of Open Access Journals (Sweden)

Kožul Nataša

2014-01-01

Full Text Available In financial research and practice, it is widely accepted that nominal interest rates derived from the prices of various financial products of different maturities comprise of corresponding real interest rates and inflation. While extensive research has been conducted on the relationship between these three variables, estimation of their levels is still largely based on the industry surveys and market data. As this information only indicates the current expectations of interest rate and inflation movements over time, a number of caveats should be noted when interpreting such measures. In the US and the UK, where the government bond markets are the largest and most active, a comparative analysis between conventional government bonds and those whose yield is linked to inflation provides a measure of inflation expectations. However, as such analyses implicitly assume that investment in government bonds is virtually risk free, it is questionable whether the derived estimates are of any value in current economic conditions. Moreover, this approach cannot be generalized to other countries, where number of traded products from which any relationship between interest rates and inflation can be determined is limited and different economic conditions prevail. Thus, this paper aims to present an overview of the methodologies used to forecast inflation rates from government bond prices, drawing attention to the key assumptions and limitations of these approaches. The goal is to ascertain their accuracy, and thus their value in determining the real yields of various interest rate-linked products.

Herbivore effects on productivity vary by guild: cattle increase mean productivity while wildlife reduce variability.

Wild herbivores and livestock share the majority of rangelands worldwide, yet few controlled experiments have addressed their individual, additive, and interactive impacts on ecosystem function. While ungulate herbivores generally reduce standing biomass, their effects on aboveground net primary production (ANPP) can vary by spatial and temporal context, intensity of herbivory, and herbivore identity and species richness. Some evidence indicates that moderate levels of herbivory can stimulate aboveground productivity, but few studies have explicitly tested the relationships among herbivore identity, grazing intensity, and ANPP. We used a long-term exclosure experiment to examine the effects of three groups of wild and domestic ungulate herbivores (megaherbivores, mesoherbivore wildlife, and cattle) on herbaceous productivity in an African savanna. Using both field measurements (productivity cages) and satellite imagery, we measured the effects of different herbivore guilds, separately and in different combinations, on herbaceous productivity across both space and time. Results from both productivity cage measurements and satellite normalized difference vegetation index (NDVI) demonstrated a positive relationship between mean productivity and total ungulate herbivore pressure, driven in particular by the presence of cattle. In contrast, we found that variation in herbaceous productivity across space and time was driven by the presence of wild herbivores (primarily mesoherbivore wildlife), which significantly reduced heterogeneity in ANPP and NDVI across both space and time. Our results indicate that replacing wildlife with cattle (at moderate densities) could lead to similarly productive but more heterogeneous herbaceous plant communities in rangelands. © 2016 by the Ecological Society of America.

Factors influencing consumption of farmed seafood products in the Pacific northwest.

Science.gov (United States)

Hall, Troy E; Amberg, Shannon M

2013-07-01

This study used a mail survey (n=1159 usable surveys) of Pacific northwest (US) residents to understand general seafood preferences (familiarity, price, freshness, health and environmental concerns), beliefs and attitudes specific to aquaculture versus wild products, and how those cognitive factors affect decisions to consume types of farmed seafood products. Respondents strongly agreed that seafood is healthy, and they preferred wild over farmed products. Many respondents were uncertain about human health and environmental benefits and problems associated with aquaculture. While there was agreement that aquaculture reduces pressure on wild fish, there was equally strong agreement that it has the same problems as other agricultural practices. Belief in the superiority of wild seafood was a strong predictor of consumption choices. Belief in the benefits of aquaculture was positively related to higher consumption of farmed products, but--unexpectedly--beliefs related to environmental and health problems associated with aquaculture did not predict specific consumption choices. Nearly half of respondents recalled hearing or reading about aquaculture in the mass media, and recall of negative stories contributed to a general preference for wild products, but not consumption of specific types of farmed products. Consumption of the different classes of products had some different predictors, and communication efforts directed at different beliefs may have different impacts on consumer behavior.

Increased riboflavin production from activated bleaching earth by a mutant strain of Ashbya gossypii.

Science.gov (United States)

Tajima, Satoshi; Itoh, Yoko; Sugimoto, Takashi; Kato, Tatsuya; Park, Enoch Y

2009-10-01

The production of riboflavin from vegetable oil was increased using a mutant strain of Ashbya gossypii. This mutant was generated by treating the wild-type strain with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG). Riboflavin production was 10-fold higher in the mutant compared to the wild-type strain. The specific intracellular catalase activity after 3 d of culture was 6-fold higher in the mutant than in the wild-type strain. For the mutant, riboflavin production in the presence of 40 mM hydrogen peroxide was 16% less than that in the absence of hydrogen peroxide, whereas it was 56% less for the wild-type strain. The isocitrate lyase (ICL) activity of the mutant was 0.26 mU/mg of protein during the active riboflavin production phase, which was 2.6-fold higher than the wild-type strain. These data indicate that the mutant utilizes the carbon flux from the TCA cycle to the glyoxylate cycle more efficiently than the wild-type strain, resulting in enhanced riboflavin production. This novel mutant has the potential to be of use for industrial-scale riboflavin production from waste-activated bleaching earth (ABE), thereby transforming a useless material into a valuable bioproduct.

Whilst remarkable progress in elucidating the mechanisms governing interspecies transmission and pathogenicity of highly pathogenic avian influenza viruses (AIVs) has been made, similar studies focusing on low-pathogenic AIVs isolated from the wild waterfowl reservoir are limited. We previously reported that two AIV strains (subtypes H6N2 and H3N8) isolated from wild waterfowl in Zambia harbored some amino acid residues preferentially associated with human influenza virus proteins (so-called human signatures) and replicated better in the lungs of infected mice and caused more morbidity than a strain lacking such residues. To further substantiate these observations, we infected chickens and mice intranasally with AIV strains of various subtypes (H3N6, H3N8, H4N6, H6N2, H9N1 and H11N9) isolated from wild waterfowl in Zambia. Although some strains induced seroconversion, all of the tested strains replicated poorly and were nonpathogenic for chickens. In contrast, most of the strains having human signatures replicated well in the lungs of mice, and one of these strains caused severe illness in mice and induced lung injury that was characterized by a severe accumulation of polymorphonuclear leukocytes. These results suggest that some strains tested in this study may have the potential to infect mammalian hosts directly without adaptation, which might possibly be associated with the possession of human signature residues. Close monitoring and evaluation of host-associated signatures may help to elucidate the prevalence and emergence of AIVs with potential for causing zoonotic infections.

Use of sugarcane molasses "B" as an alternative for ethanol production with wild-type yeast Saccharomyces cerevisiae ITV-01 at high sugar concentrations.

Fernández-López, C L; Torrestiana-Sánchez, B; Salgado-Cervantes, M A; García, P G Mendoza; Aguilar-Uscanga, M G

Molasses "B" is a rich co-product of the sugarcane process. It is obtained from the second step of crystallization and is richer in fermentable sugars (50-65%) than the final molasses, with a lower non-sugar solid content (18-33%); this co-product also contains good vitamin and mineral levels. The use of molasses "B" for ethanol production could be a good option for the sugarcane industry when cane sugar prices diminish in the market. In a complex medium like molasses, osmotolerance is a desirable characteristic for ethanol producing strains. The aim of this work was to evaluate the use of molasses "B" for ethanol production using Saccharomyces cerevisiae ITV-01 (a wild-type yeast isolated from sugarcane molasses) using different initial sugar concentrations (70-291 g L(-1)), two inoculum sizes and the addition of nutrients such as yeast extract, urea, and ammonium sulphate to the culture medium. The results obtained showed that the strain was able to grow at 291 g L(-1) total sugars in molasses "B" medium; the addition of nutrients to the culture medium did not produce a statistically significant difference. This yeast exhibits high osmotolerance in this medium, producing high ethanol yields (0.41 g g(-1)). The best conditions for ethanol production were 220 g L(-1) initial total sugars in molasses "B" medium, pH 5.5, using an inoculum size of 6 × 10(6) cell mL(-1); ethanol production was 85 g L(-1), productivity 3.8 g L(-1 )h(-1) with 90% preserved cell viability.

Environmental Surveillance System To Track Wild Poliovirus Transmission

Science.gov (United States)

Deshpande, Jagadish M.; Shetty, Sushmitha J.; Siddiqui, Zaeem A.

2003-01-01

Eradication of poliomyelitis from large metropolis cities in India has been difficult due to high population density and the presence of large urban slums. Three paralytic poliomyelitis cases were reported in Mumbai, India, in 1999 and 2000 in spite of high immunization coverage and good-quality supplementary immunization activities. We therefore established a systematic environmental surveillance study by weekly screening of sewage samples from three high-risk slum areas to detect the silent transmission of wild poliovirus. In 2001, from among the 137 sewage samples tested, wild poliovirus type 1 was isolated from 35 and wild poliovirus type 3 was isolated from 1. Acute flaccid paralysis (AFP) surveillance indicated one case of paralytic poliomyelitis from the city. Phylogenetic analysis with complete VP1 sequences revealed that the isolates from environmental samples belonged to four lineages of wild polioviruses recently isolated from poliomyelitis cases in Uttar Pradesh and not to those previously isolated from AFP cases in Mumbai. Wild poliovirus thus introduced caused one case of paralytic poliomyelitis. The virus was detected in environmental samples 3 months before. It was found that wild polioviruses introduced several times during the year circulated in Mumbai for a limited period before being eliminated. Environmental surveillance was found to be sensitive for the detection of wild poliovirus silent transmission. Nucleotide sequence analysis helped identify wild poliovirus reservoir areas.

The invasion of the wild oyster Crassostrea gigas along the western European Atlantic coast has generated changes in the structure and functioning of intertidal ecosystems. Considered as an invasive species and a trophic competitor of the cultivated conspecific oyster, it is now seen as a resource by oyster farmers following recurrent mass summer mortalities of oyster spat since 2008. Spatial distribution maps of wild oyster reefs are required by local authorities to help define management strategies. In this work, visible-near infrared (VNIR) hyperspectral and multispectral remote sensing was investigated to map two contrasted intertidal reef structures: clusters of vertical oysters building three-dimensional dense reefs in muddy areas and oysters growing horizontally creating large flat reefs in rocky areas. A spectral library, collected in situ for various conditions with an ASD spectroradiometer, was used to run Spectral Angle Mapper classifications on airborne data obtained with an HySpex sensor (160 spectral bands) and SPOT satellite HRG multispectral data (3 spectral bands). With HySpex spectral/spatial resolution, horizontal oysters in the rocky area were correctly classified but the detection was less efficient for vertical oysters in muddy areas. Poor results were obtained with the multispectral image and from spatially or spectrally degraded HySpex data, it was clear that the spectral resolution was more important than the spatial resolution. In fact, there was a systematic mud deposition on shells of vertical oyster reefs explaining the misclassification of 30% of pixels recognized as mud or microphytobenthos. Spatial distribution maps of oyster reefs were coupled with in situ biomass measurements to illustrate the interest of a remote sensing product to provide stock estimations of wild oyster reefs to be exploited by oyster producers. This work highlights the interest of developing remote sensing techniques for aquaculture applications in coastal

2014-01-01

Full Text Available The paper presents the most important parasitic infections of wild rabbits and hares, which harmful effect in this animal population is manifested as a gradual weakening of the immune system, reduction in fertility, weight loss and constant exhaustion. Order of Lagomorpha (hares or lagomorphs belongs to superorder of higher mammals which includes the family of rabbits (Leporidae which are represented in Europe as well as the family of whistleblowers (Ochotonidae which live only in North America and Northern regions of Asia. The most important representatives of Leporidae family are European hare (Lepus europeus and wild rabbit (Oryctolagus cuniculus. The most important endoparasitosis of hares and wild rabbits are: coccidiosis, encephalitozoonosis (nosemosis, toxoplasmosis, sarcocystosis, giardiasis, cryptosporidiosis, protostrongylosis, trichostrngylodosis, passalurosis, anoplocephalidosis, cysticercosis and fasciolosis. The most frequent ectoparasites of rabbits and wild hares are fleas, lice and ticks. Reduction in hare population, which is noticed in whole Europe including Serbia, is caused by changed living conditions, quantitatively and qualitatively insufficient nutrition, increased use of herbicides as well as various infectious diseases and the diseases of parasitic etiology. Since wild rabbits and hares pose a threat to health of domestic rabbits and people, knowledge of parasitic fauna of these wild animals is of extreme epizootiological and epidemiological importance.

Salmon lice – impact on wild salmonids and salmon aquaculture

Torrissen, O; Jones, S; Asche, F; Guttormsen, A; Skilbrei, O T; Nilsen, F; Horsberg, T E; Jackson, D

2013-01-01

Salmon lice, Lepeophtheirus salmonis, are naturally occurring parasites of salmon in sea water. Intensive salmon farming provides better conditions for parasite growth and transmission compared with natural conditions, creating problems for both the salmon farming industry and, under certain conditions, wild salmonids. Salmon lice originating from farms negatively impact wild stocks of salmonids, although the extent of the impact is a matter of debate. Estimates from Ireland and Norway indicate an odds ratio of 1.1:1-1.2:1 for sea lice treated Atlantic salmon smolt to survive sea migration compared to untreated smolts. This is considered to have a moderate population regulatory effect. The development of resistance against drugs most commonly used to treat salmon lice is a serious concern for both wild and farmed fish. Several large initiatives have been taken to encourage the development of new strategies, such as vaccines and novel drugs, for the treatment or removal of salmon lice from farmed fish. The newly sequenced salmon louse genome will be an important tool in this work. The use of cleaner fish has emerged as a robust method for controlling salmon lice, and aquaculture production of wrasse is important towards this aim. Salmon lice have large economic consequences for the salmon industry, both as direct costs for the prevention and treatment, but also indirectly through negative public opinion. PMID:23311858

This paper is comprised of written text and photographs of wild experiences that relive a series of ontological experiments. The text represents reflections on these experiences. The photographs, artistic expressions of the same experiences, have been made with a homemade pinhole camera—without a lens and viewfinder—thus demanding special sensual presence during creation. The form of this experimental work is reminiscent of a lyric philosophy that seeks to engage the participant—reader of text and viewer of images—with these experiments. Component pairings are arranged for viewing with text on the left and photographs on the right. Together these parings invite participants to explore patterned resonances in the world. Implicit throughout are considerations of relationships between wildness, wild learning, and a form of wild pedagogy.

Joint ventures between industry and government

International Nuclear Information System (INIS)

Vant, T.R.

1991-01-01

Joint venture projects undertaken between government and industry in western Canada are reviewed. The first significant involvement of the Alberta government was with the Syncrude oil sands project. In 1974, one of the original participants, Atlantic Richfield, pulled out of Syncrude for financial reasons. After a government review and search for replacement participation, three provincial governments took equity positions in the project. The Syncrude project has since had a very significant impact on Alberta and Canada in terms of oil production, employment, investment, and profits. The Other Six Leases Operation (OSLO), the OSLO New Ventures Project, and the Lloydminster Bi-Provincial Upgrader would also not have advanced to their present stages of development without government participation. Since oil sand/heavy oil development requires significant capital investment over long lead times, and since there are few private companies that can undertake such a commitment, government assistance is often required. It also makes sense for governments to share upfront risk in such projects for both the long-term economic gain and such immediate benefits as job creation and energy supply security. An industry/government joint venture provides a means of getting large, inherently economic projects such as oil sands developments under way while protecting taxpayers' interests. The success of such a joint venture depends not only on the financing brought to the project but also on the expertise, decision making capability, and balanced management of regulatory and policy issues

Fukushima, Crisis of a Model of Governance

International Nuclear Information System (INIS)

Delamotte, Guibourg

2013-01-01

The year following the March 11, 2011, Fukushima catastrophe was a period of stock taking, self-criticism, and adjustment: a model of governance was on trial in Japan. In order to avoid widespread panic, the government chose to under-inform the population. Yet the government itself was very poorly informed, and the agencies on which it depended in this domain did not possess the firsthand information or expertise they were supposed to supply. Of all the actors involved in managing the nuclear crisis, the government was no doubt the least at fault. The operator surveillance body, the Nuclear and Industrial Safety Agency, and the operator, TEPCO, were both aware that safety standards had been neglected at the Fukushima Daiichi reactor. The various reports produced since the catastrophe have shed light on the failings of a system of governance, and the Japanese government has quickly drawn lessons from them. The doubts that were thus raised concerning the place of the nuclear sector in energy production were nevertheless shelved following the return to power of a liberal-democrat majority in December 2012

Wing Morphometry and Acoustic Signals in Sterile and Wild Males: Implications for Mating Success in Ceratitis capitata

2015-01-01

Full Text Available The sterile insect technique (SIT is widely utilized in the biological control of fruit flies of the family Tephritidae, particularly against the Mediterranean fruit fly. This study investigated the interaction between mating success and morphometric variation in the wings and the production of acoustic signals among three male groups of Ceratitis capitata (Wiedemann: (1 wild males, (2 irradiated with Co-60 (steriles, and (3 irradiated (steriles and treated with ginger oil. The canonical variate analysis discriminated two groups (males irradiated and males wild, based on the morphological shape of the wings. Among males that emit buzz signals, wild males obtained copulation more frequently than males in Groups 2 and 3. The individuals of Group 3 achieved more matings than those in Group 2. Wild males displayed lower pulse duration, higher intervals between pulses, and higher dominant frequency. Regarding the reproductive success, the morphological differences in the wings’ shape between accepted and nonaccepted males are higher in wild males than in the irradiated ones. The present results can be useful in programs using the sterile insect technique for biological control of C. capitata.

Mycoplasma gallopavonis in eastern wild turkeys.

Luttrell, M P; Eleazer, T H; Kleven, S H

1992-04-01

Serum samples and tracheal cultures were collected from eastern wild turkeys (Meleagris gallopavo sylvestris) trapped for relocation in South Carolina (USA) during 1985 to 1990. Sera were tested for Mycoplasma gallisepticum and M. synoviae by the rapid plate agglutination and hemagglutination inhibition tests and were found to be negative. Tracheal cultures were negative for all pathogenic Mycoplasma spp., including M. gallisepticum, M. synoviae, M. meleagridis, and M. iowae. However, M. gallopavonis was isolated from every group of wild turkeys tested in 1986 to 1990. These data suggest that M. gallopavonis, which is generally considered nonpathogenic, may be a common microorganism in eastern wild turkeys.

Genotype-temperature interaction in the regulation of development, growth, and morphometrics in wild-type, and growth-hormone transgenic coho salmon.

Directory of Open Access Journals (Sweden)

Mare Lõhmus

2010-04-01

Full Text Available The neuroendocrine system is an important modulator of phenotype, directing cellular genetic responses to external cues such as temperature. Behavioural and physiological processes in poikilothermic organisms (e.g. most fishes, are particularly influenced by surrounding temperatures.By comparing the development and growth of two genotypes of coho salmon (wild-type and transgenic with greatly enhanced growth hormone production at six different temperatures, ranging between 8 degrees and 18 degrees C, we observed a genotype-temperature interaction and possible trend in directed neuroendocrine selection. Differences in growth patterns of the two genotypes were compared by using mathematical models, and morphometric analyses of juvenile salmon were performed to detect differences in body shape. The maximum hatching and alevin survival rates of both genotypes occurred at 12 degrees C. At lower temperatures, eggs containing embryos with enhanced GH production hatched after a shorter incubation period than wild-type eggs, but this difference was not apparent at and above 16 degrees C. GH transgenesis led to lower body weights at the time when the yolk sack was completely absorbed compared to the wild genotype. The growth of juvenile GH-enhanced salmon was to a greater extent stimulated by higher temperatures than the growth of the wild-type. Increased GH production significantly influenced the shape of the salmon growth curves.Growth hormone overexpression by transgenesis is able to stimulate the growth of coho salmon over a wide range of temperatures. Temperature was found to affect growth rate, survival, and body morphology between GH transgenic and wild genotype coho salmon, and differential responses to temperature observed between the genotypes suggests they would experience different selective forces should they ever enter natural ecosystems. Thus, GH transgenic fish would be expected to differentially respond and adapt to shifts in environmental

The requirements and procedures for acquiring such a marketing authorisation are laid down in regulations, directives and scientific guidelines. This paper gives an overview of the quality requirements for (traditional) herbal medicinal products that are contained in European pharmaceutical legislation. Pharmaceutical quality of medicinal product is the basis for ensuring safe and effective medicines. The basic principles governing the assurance of the quality of medicinal products in the European Union are primarily defined in the amended Directive 2001/83/EC and Directive 2003/63/EC. Quality requirements of herbal medicinal products are also laid down in scientific guidelines. Scientific guidelines provide a basis for practical harmonisation of how the competent authorities of EU Member States interpret and apply the detailed requirements for the demonstration of quality laid down in regulations and directives. Detailed quality requirements for herbal medicinal products on the European market are contained in European Union (EU) pharmaceutical legislation. They include a system of manufacturing authorisations which ensures that all herbal medicinal products on the European market are manufactured/imported only by authorised manufacturers, whose activities are regularly inspected by the competent authorities. Additionally, as starting materials only active substances are allowed which have been manufactured in accordance with the GMP for starting materials as adopted by the Community. The European regulatory framework encompasses specific requirements for herbal medicinal products. These requirements are independent from the legal status. Thus, the same quality standards equally apply

Aseptic meningitis and acute parotitis have been observed after mumps vaccination. Mumps outbreaks have been reported in Japan because of low vaccine coverage, and molecular differentiation is required to determine whether these cases are vaccine associated. RT-nested PCR was performed in the small hydrophobic gene region, and viruses were differentiated by restriction fragment length polymorphism assay. A total of 584 nucleotides were amplified. The PCR product of the Hoshino strain was cut into two fragments (313 and 271 nucleotides) by MfeI; that of the Torii strain was digested with EcoT22I, resulting in 332- and 252-nucleotide fragments. Both strains were genotype B and had an XbaI site, resulting in two fragments: 299 and 285 nucleotides. Current circulating wild types were cut only by XbaI or MfeI. However, the MfeI site of the wild types was different from that of the Hoshino strain, resulting in 451- and 133-nucleotide fragments. Using three restriction enzymes, two mumps vaccine strains were distinguished from wild types, and this separation was applied to the identification of vaccine-related adverse events.

Comparative proteomic analysis of aluminum tolerance in tibetan wild and cultivated barleys.

Full Text Available Aluminum (Al toxicity is a major limiting factor for plant production in acid soils. Wild barley germplasm is rich in genetic diversity and may provide elite genes for crop Al tolerance improvement. The hydroponic-experiments were performed to compare proteomic and transcriptional characteristics of two contrasting Tibetan wild barley genotypes Al- resistant/tolerant XZ16 and Al-sensitive XZ61 as well as Al-resistant cv. Dayton. Results showed that XZ16 had less Al uptake and translocation than XZ61 and Dayton under Al stress. Thirty-five Al-tolerance/resistance-associated proteins were identified and categorized mainly in metabolism, energy, cell growth/division, protein biosynthesis, protein destination/storage, transporter, signal transduction, disease/defense, etc. Among them, 30 were mapped on barley genome, with 16 proteins being exclusively up-regulated by Al stress in XZ16, including 4 proteins (S-adenosylmethionine-synthase 3, ATP synthase beta subunit, triosephosphate isomerase, Bp2A specifically expressed in XZ16 but not Dayton. The findings highlighted the significance of specific-proteins associated with Al tolerance, and verified Tibetan wild barley as a novel genetic resource for Al tolerance.

For the evaluation of internal radiation dose, it is needed to estimate the amount of radionuclide incorporated to human body using a simulation model. 137 Cesium (Cs) is easily transferred associating with food intake as well as potassium and so, Cs is an important nuclide for evaluation of internal radiation. 137 Cs concentrations in wild vegetables are higher than those of cultured vegetables and milk. Therefore, the transfer coefficients of 137 Cs from soil to wild vegetables were estimated in this study. Wild vegetables and soils of their farms were collected in the Hakkoda Mountain range of Aomori Prefecture. The levels of 137 Cs in wild vegetables were 0.42-18.35 (Bq/kg), whereas those in cabbage and spinach were 0.08 and 0.01 (Bq/kg), respectively, indicating that the Cs level is dozens to several hundreds times higher in wild vegetables than cultured ones. And the transfer coefficient was estimated as 0.003-0.94 for the former and 0.001-0.8 for the latter. On the other hand, 1 37 Cs levels of the soils on which wild vegetables grew was 28.0 Bq/kg and it was 3.9 Bq/kg for the farm soil. Furthermore, the effects of water content and pH of the soil on the transfer coefficient were studied. (M.N.)

Secrets of Success in a Landscape of Fear: Urban Wild Boar Adjust Risk Perception and Tolerate Disturbance

Directory of Open Access Journals (Sweden)

Milena Stillfried

2017-12-01

Full Text Available In urban areas with a high level of human disturbance, wildlife has to adjust its behavior to deal with the so called “landscape of fear.” This can be studied in risk perception during movement in relation to specific habitat types, whereby individuals trade-off between foraging and disturbance. Due to its high behavioral plasticity and increasing occurrence in urban environments, wild boar (Sus scrofa is an excellent model organism to study adjustment to urbanization. With the help of GPS tracking, space use of 11 wild boar from Berlin's metropolitan region was analyzed: we aimed at understanding how animals adjust space use to deal with the landscape of fear in urban areas compared to rural areas. We compared use vs. availability with help of generalized linear mixed models. First, we studied landscape types selected by rural vs. urban wild boar, second, we analyzed distances of wild boar locations to each of the landscape types. Finally, we mapped the resulting habitat selection probability to predict hotspots of human-wildlife conflicts. A higher tolerance to disturbance in urban wild boar was shown by a one third shorter flight distance and by an increased re-use of areas close to the trap. Urban wild boar had a strong preference for natural landscapes such as swamp areas, green areas and deciduous forests, and areas with high primary productivity, as indicated by high NDVI (normalized difference vegetation index values. The areas selected by urban wild boar were often located closely to roads and houses. The spatial distribution maps show that a large area of Berlin would be suitable for urban wild boar but not their rural conspecifics, with the most likely reason being a different perception of anthropogenic disturbance. Wild boar therefore showed considerable behavioral plasticity suitable to adjust to human-dominated environments in a potentially evolutionarily adaptive manner.

Can corruption favour growth via the composition of government spending?

OpenAIRE

Sugata Ghosh; Andros Gregoriou

2010-01-01

In an endogenous growth model with two public goods, we analytically derive the optimal composition of government spending in the presence of corruption. Although corruption results in a loss of productivity per se, an increase in corruption in the category of public spending that is harmed relatively more by corruption could have a favourable effect on growth, as it would encourage a benevolent government to divert spending towards the public good that is more productive, net of corruption.

Mongolia combines a near absence of domestic poultry, with an abundance of migratory waterbirds, to create an ideal location to study the epidemiology of highly pathogenic avian influenza virus (HPAIV) in a purely wild bird system. Here we present the findings of active and passive surveillance for HPAIV subtype H5N1 in Mongolia from 2005–2011, together with the results of five outbreak investigations. In total eight HPAIV outbreaks were confirmed in Mongolia during this period. Of these, one was detected during active surveillance employed by this project, three by active surveillance performed by Mongolian government agencies, and four through passive surveillance. A further three outbreaks were recorded in the neighbouring Tyva Republic of Russia on a lake that bisects the international border. No HPAIV was isolated (cultured) from 7,855 environmental fecal samples (primarily from ducks), or from 2,765 live, clinically healthy birds captured during active surveillance (primarily shelducks, geese and swans), while four HPAIVs were isolated from 141 clinically ill or dead birds located through active surveillance. Two low pathogenic avian influenza viruses (LPAIV) were cultured from ill or dead birds during active surveillance, while environmental feces and live healthy birds yielded 56 and 1 LPAIV respectively. All Mongolian outbreaks occurred in 2005 and 2006 (clade 2.2), or 2009 and 2010 (clade 2.3.2.1); all years in which spring HPAIV outbreaks were reported in Tibet and/or Qinghai provinces in China. The occurrence of outbreaks in areas deficient in domestic poultry is strong evidence that wild birds can carry HPAIV over at least moderate distances. However, failure to detect further outbreaks of clade 2.2 after June 2006, and clade 2.3.2.1 after June 2010 suggests that wild birds migrating to and from Mongolia may not be competent as indefinite reservoirs of HPAIV, or that HPAIV did not reach susceptible populations during our study.

The population history of the Iberian wild goat and the Alpine ibex has been closely related to that of humans since the Palaeolithic. Current molecular and paleontological studies differ substantially on the phylogenetic origin of the European wild goats, possibly due the loss of genetic variation through time. We investigated the phylogenetic relationship between the Alpine ibex (Capra ibex) and the Iberian wild goat (Capra pyrenaica) including different Iberian wild goat subspecies by applying ancient DNA techniques combined with Next Generation Sequencing technologies. We analysed the cytochrome b gene of the mitochondrial genome in 33 ancient and modern European wild goats from Spain and France together with publicly available genetic information of modern wild goats. This work uncovers for the first time ancient genetic information of the Iberian wild goat and the Alpine ibex, spanning a time range of approximately 40,000 years to the present. Our results suggest genetic continuity between ancient and modern populations and indicate a monophyletic origin of the Alpine ibex and the Iberian wild goat when compared to other Capra species. The monophyly of both species is in agreement with other molecular studies based only on modern populations, therefore supporting one-wave migration of wild goats into Western Europe followed by possible allopatric speciation. We observe three major clades of wild goats in Western Europe: Capra ibex, Capra pyrenaica pyrenaica and the group containing the subspecies Capra pyrenaica hispanica and Capra pyrenaica victoriae. This genetic structure recognizes the distinctiveness of the bucardo (C. p. pyrenaica) from the rest of Iberian wild goats and thus supports the idea that this group is an Evolutionary Significant Unit. The divergence time estimated here indicates an almost contemporaneous split between the three clades around 50,000-90,000 years BP.

To discover the effect of environmental factors on pollinator visitation to flowering Medicago sativa, several field experiments were designed to examine the diurnal movement patterns of wild bee species in the Hexi Corridor of northwestern China. Our study results showed that Megachile abluta, M. spissula, and Xylocopa valga showed unimodal diurnal foraging behavior, whereas Andrena parvula and Anthophora melanognatha showed bimodal diurnal foraging behavior. Correlation analysis indicated that diurnal foraging activities of pollinators were significantly correlated with environmental factors. Correlations of foraging activities versus environmental factors for M. abluta, M. spissula, and X. valga best fit a linear model, whereas those of A. parvula and A. melanognatha best fit a parallel quadratic model. Results of this study indicated that solitary wild bees such as M. abluta, M. spissula, X. valga, A. parvula, and A. melanognatha are potential alfalfa pollinators in the Hexi Corridor. An understanding of the environmental factors that affect the behaviors of different wild bees foraging in alfalfa are basic to the utilization of solitary wild bees in a practical way for increased, or more consistent, pollination of alfalfa for seed production.

What governs governance, and how does it evolve? The sociology of governance-in-action.

Fox, Nick J; Ward, Katie J

2008-09-01

Governance addresses a wide range of issues including social, economic and political continuity, security and integrity, individual and collective safety and the liberty and rights to self-actualization of citizens. Questions to be answered include how governance can be achieved and sustained within a social context imbued with cultural values and in which power is distributed unevenly and dynamically, and how governance impacts on individuals and institutions. Drawing on Gramscian notions of hegemony and consent, and recent political science literatures on regulation and meta-regulation, this paper develops a sociological model of governance that emphasizes a dynamic and responsive governance in action. Empirical data from a study of pharmaceutical governance is used to show how multiple institutions and actors are involved in sustaining effective governance. The model addresses issues of how governance is sustained in the face of change, why governance of practices varies from setting to setting, and how governance is achieved without legislation.

Arch G. Woodside

2013-07-01

Full Text Available This article develops theory and examines relationships among reforms in government regulation of business, competitiveness, and national economic development in term of GDP per capita. The findings shed light on the ongoing debate of supporting versus refuting reducing/eliminating government regulations of business. Applying Campbell’s (1968, 1969 seminal contributions in examining the impact of reforms as quasi-experiments and Mill’s (1872/1973 method of differences, the study shows that the reforms in reductions and eliminations of government regulations of business help to increase national economic growth the lagged impact (e.g., 2, 3 years after introduction of reforms should be expected. Also, medium-to-large reductions in the ranking of government regulations of business (increase in competitiveness associate with increases in GDP per capita in comparison to a large increase in the ranking (decrease in competitiveness. The results also provide insights into the different regulatory environments (i.e., high vs. low government corruption and media-freedom vs. highly ethical behavior and lack of media-freedom may condition the impact of the reforms.

Comparison of ovarian maturation and spawning after unilateral eyestalk ablation of wild-caught and pond-reared Penaeus monodon

The present study compares the efficiency of ovarian maturation and spawning success between wild-caught and pond-reared Penaeus monodon females after unilateral eyestalk ablation. The earliest spawning time after eyestalk ablation was 5.9 days in wild-caught females, which is significantly shorter than the spawning time in pond-reared females (10.5 days). Both wild-caught and pond-reared females repeatedly spawned after eyestalk ablation. On average, each wild-caught female spawned 2.94 times while each pond-reared female spawned only 1.09 times. The spawning induction rate, egg hatching rate, and the number of eggs per spawning were significantly greater in wild-caught females than in pond-reared females. However, the egg size was not significantly different between wild-caught and pond-reared females. Four shrimp sizes (60, 80, 100 and 120 (± 1.0) g) were tested in this study and body weight significantly affected ovarian induction in pond-reared females but not in wild-caught females. Within the same body-weight class, the egg number per spawn in wild-caught females was significantly greater than that in pond-reared females. The egg production per spawn of the pond-reared females in the 120-g size group was two times higher than that in the pond-reared females in the 80-g size group. In conclusion, the fecundity of wild-caught P. monodon females is significantly higher than that of pond-reared P. monodon females. In breeding pond-reared P. monodon, the recommended minimum body weight of females is over 80 g, and the desirable body weight is over 100 g. (Author)

Wild-Caught Versus Farmed Fish – Consumer Perception

Directory of Open Access Journals (Sweden)

Tomić Marina

2017-06-01

Full Text Available We have limited knowledge of determinants of consumer preferences for wild-caught versus farmed-raised fish, so this work aims to investigate the impact of sociodemographics, habits and frequency of fresh fish consumption, such as involvement in cooking, on the preferences for wild versus farmed fish. A survey was done on a sample of 1151 fish consumers in Croatia. Results showed that female, older consumers, consumers with higher income and those living in coastal parts of Croatia give higher preferences for wild fish and they detect differences between the taste of wild and farmed fish. Consumers with higher levels of habits of fresh fish consumption, who eat fresh fish often and are more involved in cooking, prefer wild-caught fish. These findings provide valuable information for the aquaculture sector, especially for planning marketing strategies for the promotion of farmed fish.

Development of attenuated mutants for use as vaccines is in progress for other viruses, including influenza, rotavirus, varicella-zoster, cytomegalovirus, and hepatitis-A virus (HAV). Attenuated viruses may be derived from naturally occurring mutants that infect human or nonhuman hosts. Alternatively, attenuated mutants may be generated by passage of wild-type virus in cell culture. Production of attenuated viruses in cell culture is a laborious and empiric process. Despite previous empiric successes, understanding the molecular basis for attenuation of vaccine viruses could facilitate future development and use of live-virus vaccines. Comparison of the complete nucleotide sequences of wild-type (virulent) and vaccine (attenuated) viruses has been reported for polioviruses and yellow fever virus. Here, the authors compare the nucleotide sequence of wild-type HAV HM-175 with that of a candidate vaccine derivative

Ja`Afar-Furo, M. R.; Balla, H. G.; Tahir, A. S.; Haskainu, C.

Reducing the huge economic losses due to diseases in poultry as the second largest industry in Nigeria after oil means improving the protein intake of the majority. Similarly, this will also promotes a steady income for the teeming farmers. This study investigated the incidence of the lethal avian influenza in Adamawa State, Nigeria, with particular emphasis on the socio-economic and cultural activities of the poultry farmers, economic losses and the possible role of wild birds in the transmission of the disease. Data were collected from 316 and 458 direct and indirect respondents, respectively, from 6 affected villages and a town in 2 Local Government Areas (LGAs): Girei and Yola-North. Results revealed that a larger (25.71%) proportion of the respondents fell within the age range of 31-40 years, with majority (54.91%) as females. While the bulk (54.65%) of the respondents were illiterates, 95.47% of the direct respondents derived their incomes from crop production, whereas 59.17% of the indirect respondents from livestock rearing. About 26,049 birds worth N13, 454,800.00 was cumulative economic loss incurred by the poultry farmers, whereas that of the government was put at N1, 119,781.10. Of the mortalities experienced in the wildlife before the outbreak of the disease, Bubulcus ibis (64.29) and Tadarida nigeriae (86.36) were the highest. The study recommends a massive rural extension on Poultry Production with absolute biosecurity, involving all stakeholders (Veterinary Surgeons, Animal Scientists/health workers, wildlife specialists, Agricultural Economists, Information Officers etc.) in a collaborative form for high synergistic effects.

Despite its promising prospects, a growing global bio-energy market may have sustainability risks as well. Governing this market with respect to installing safeguards to ensure sustainable biomass production might reduce these risks. Therefore, proposals for governance systems for bio-energy are discussed in this article. The proposals are based on comparative case study research on the governance of comparable commodities. By assessing the governance system of global coffee trade, fair trade coffee, the global and the EU sugar market and Forest Stewardship Council (FSC) wood, strong and weak points of governance systems for commodities are discerned. FSC is selected as the best performing case study and serves as the proposal's basis. FSC's weaknesses are minimized by, among others, using the lessons learned from the other case studies. This results in a system consisting of two pillars, a bio-energy labelling organization (BLO) and a United Nations Agreement on Bio-energy (UNAB). Although consulted experts in the research process are critical about this system they do suggest several conditions a governance system for bio-energy should meet in order to be effective, such as a facilitative government, professional monitoring and using progressive certification combined with price premiums. These conditions have been taken into account in the final proposal. (author)

Full Text Available The objectives of this study were to determine the pattern of dry matter (DM accumulation and the evolution of phenolic compounds in the rhizosphere soil from tillering to the ripe seed stages of wild oat (Avena fatua L., a widespread annual grassy weed. Plants were grown under controlled conditions and harvested 13 times during the growing season. At each harvest, shoot and root DM and phenolic compounds in the rhizosphere soil were determined. The maximum DM production (12.6 g/plant was recorded at 122 days after sowing (DAS; kernel hard stage. The increase in total aerial DM with age coincided with reductions in the leaf/stem and source/sink ratios, and an increase in the shoot/root ratio. HPLC analysis shows production of seven phenolic compounds in the rhizosphere soil of wild oat, in order of their decreasing levels: syringic acid, vanillin, 4-hydroxybenzoic acid, syringaldehyde, ferulic acid, p-cumaric acid and vanillic acid. The seasonal distribution for the total phenolic compounds showed two peaks of maximum concentrations, at the stem elongation stage (0.71 μg/kg; 82 DAS and at the heading stage (0.70 μg/kg; 98 DAS. Thus wild oat roots exude allelopathic compounds, and the levels of these phenolics in the rhizosphere soil vary according to plant maturity.

The purpose of the present investigation was to produce erythritol by Yarrowia lipolytica mutant without any by-products. Mutants of Y. lipolytica were generated by ultra-violet for enhancing erythrose reductase (ER) activity and erythritol production. The mutants showing the highest ER activity were screened by triphenyl tetrazolium chloride agar plate assay. Productivity of samples was analyzed by thin-layer chromatography and high-performance liquid chromatography equipped with the refractive index detector. One of the mutants named as mutant 49 gave maximum erythritol production without any other by-products (particularly glycerol). Erythritol production and specific ER activity in mutant 49 increased to 1.65 and 1.47 times, respectively, in comparison with wild-type strain. The ER gene of wild and mutant strains was sequenced and analyzed. A general comparison of wild and mutant gene sequences showed the replacement of Asp(270) with Glu(270) in ER protein. In order to enhance erythritol production, we used a three component-three level-one response Box-Behnken of response surface methodology model. The optimum medium composition for erythritol production was found to be (g/l) glucose 279.49, ammonium sulfate 9.28, and pH 5.41 with 39.76 erythritol production.

Raising The Wild Flag: E. B. White, World Government, and Local Cosmopolitanism in the Postwar Moment

2012-01-01

This essay argues that the writer E. B. White, best known for his literary essays and children’s books, also had a significant but neglected career as a political writer. It considers his writings, during and just after World War II, on the subject of world government, and argues that he made the case for world federation by way of a novel model of cosmopolitanism that results from love of place and country rather than from dispensing with them. It considers the reception of his 1946 book The...

Nanotechnology and the need for risk governance

International Nuclear Information System (INIS)

Renn, O.; Roco, M. C.

2006-01-01

After identifying the main characteristics and prospects of nanotechnology as an emerging technology, the paper presents the general risks associated with nanotechnology applications and the deficits of the risk governance process today, concluding with recommendations to governments, industry, international organizations and other stakeholders. The International Risk Governance Council (IRGC) has identified a governance gap between the requirements pertaining to the nano- rather than the micro-/macro- technologies. The novel attributes of nanotechnology demand different routes for risk-benefit assessment and risk management, and at present, nanotechnology innovation proceeds ahead of the policy and regulatory environment. In the shorter term, the governance gap is significant for those passive nanostructures that are currently in production and have high exposure rates; and is especially significant for the several 'active' nanoscale structures and nanosystems that we can expect to be on the market in the near future. Active nanoscale structures and nanosystems have the potential to affect not only human health and the environment but also aspects of social lifestyle, human identity and cultural values. The main recommendations of the report deal with selected higher risk nanotechnology applications, short- and long-term issues, and global models for nanotechnology governance

Full Text Available Abstract Background Changing lifestyles have recently caused a severe reduction of the gathering of wild food plants. Knowledge about wild food plants and the local environment becomes lost when plants are no longer gathered. In Central Europe popular scientific publications have tried to counter this trend. However, detailed and systematic scientific investigations in distinct regions are needed to understand and preserve wild food uses. This study aims to contribute to these investigations. Methods Research was conducted in the hill country east of Graz, Styria, in Austria. Fifteen farmers, most using organic methods, were interviewed in two distinct field research periods between July and November 2008. Data gathering was realized through freelisting and subsequent semi-structured interviews. The culinary use value (CUV was developed to quantify the culinary importance of plant species. Hierarchical cluster analysis was performed on gathering and use variables to identify culture-specific logical entities of plants.

Bianke Loedolff

2017-11-01

Full Text Available Background: Brassica vegetables and leafy greens are consumed globally due to their health promoting phytochemicals. Diplotaxis tenuifolia (wild rocket or arugula is a popular Brassica leafy green, with a diverse range of phytochemicals (in mature plants. Immature plants (micro-greens, 2-4 true leaves accumulate phytochemicals up to 10 times more than plants grown to maturity. Although plants accumulate phytochemicals ubiquitously, environmental stimuli can further enhance this phenomenon of accumulation, which is part of a global stress mechanism in plants. In this study, we describe a simple method toward the bio-fortification of a wild rocket micro-green system, via environmental manipulation (using high light. Objective: To establish a high light-induced bio-fortification strategy to augment the accumulation of bio-active compounds in Brassica micro-greens (wild rocket, with the purpose of developing a ‘designer’ micro-green melange (functional food product containing a diverse range of bio-active (disease preventative compounds. Results: High light stimulated wild rocket micro-greens to achieve a significant increase of known phytochemicals (documented in relevant Brassica leafy greens. Furthermore, undocumented phytochemicals (resveratrol, catechin, epicatechin, and kaempferol, among others also accumulated to adequate concentrations. Plant extracts from bio-fortified micro-greens displayed increased anti-oxidant capacity (up to 3-fold, when compared to control, a key component in future cancer cell research. Conclusion: The use of high light resulted in successful bio-fortification of wild rocket micro-greens, evidenced by the accumulation of previously undocumented polyphenols (such as resveratrol, catechin and epicatechin and improved anti-oxidant capacity.

Interactive governance

DEFF Research Database (Denmark)

Sørensen, Eva; Torfing, Jacob; Peters, B. Guy

Governance has become one of the most commonly used concepts in contemporary political science. It is, however, often used to mean a variety of different things. This book helps to clarify this conceptual muddle by concentrating on one variety of governance-interactive governance. The authors argue...... that although the state may remain important for many aspects of governing, interactions between state and society represent an important, and perhaps increasingly important, dimension of governance. These interactions may be with social actors such as networks, with market actors or with other governments......, but all these forms represent means of governing involving mixtures of state action with the actions of other entities.This book explores thoroughly this meaning of governance, and links it to broader questions of governance. In the process of explicating this dimension of governance the authors also...

Meiotic behavior of wild Caricaceae species potentially suitable for papaya improvement

Emanuelli Narducci da Silva

2012-01-01

Full Text Available The purpose of this study was to evaluate the meiotic behavior and determine the meiotic index and pollen viability of representative plants of the wild species V. goudotiana, V. quercifolia and J. spinosa. Meiotic analysis confirmed that the species are diploid and have 18 chromosomes. Meiosis was partially normal, since some abnormalities, e.g, sticky and lagging chromosomes, precocious segregation, lack of synchrony, and disturbances in the spindle fibers were observed. These abnormalities resulted in post-meiotic products (monads, dyads, triads, and polyads that probably contributed to the meiotic index of 85.7 % (V. goudotiana to 95.9 % (J. spinosa; significant variation was observed in the species V. goudotiana. The pollen viability of 68.0% (V. goudotiana to 96.0 % (J. spinosa was reasonably good in these wild species. Crossings in breeding programs involving V. goudotiana should therefore be carefully planned, since part of the gametes of this species is unviable.

Potential Uses of Wild Germplasms of Grain Legumes for Crop Improvement

Muñoz, Nacira; Liu, Ailin; Kan, Leo; Li, Man-Wah; Lam, Hon-Ming

2017-01-01

Challenged by population increase, climatic change, and soil deterioration, crop improvement is always a priority in securing food supplies. Although the production of grain legumes is in general lower than that of cereals, the nutritional value of grain legumes make them important components of food security. Nevertheless, limited by severe genetic bottlenecks during domestication and human selection, grain legumes, like other crops, have suffered from a loss of genetic diversity which is essential for providing genetic materials for crop improvement programs. Illustrated by whole-genome-sequencing, wild relatives of crops adapted to various environments were shown to maintain high genetic diversity. In this review, we focused on nine important grain legumes (soybean, peanut, pea, chickpea, common bean, lentil, cowpea, lupin, and pigeonpea) to discuss the potential uses of their wild relatives as genetic resources for crop breeding and improvement, and summarized the various genetic/genomic approaches adopted for these purposes.

2018-02-01

Full Text Available The use of game meat as a food source is currently a growing trend in our country. These products have strong and historic ties with cultural and culinary tradition, but are also appreciated for their sensory and nutritional characteristics. A major contributor to the supply of this type of product is hunting. Practiced since the dawn of time for survival, hunting has evolved into a recreational activity with substantial commercial interests. Of particular importance in this context is hunting of large ungulates. The progressive urbanization of the population has allowed for the re-establishment of bush and wooded areas that represent the ideal habitat of species such as the wild boar, whose numbers are increasing throughout the country. It is therefore clear that implementation of safety rules regarding the hunting and consumption of game meat needs to be urgently addressed. The understanding and application of rules isn’t always easy since the health law is intertwined with that of hunting, and the decision- making power left to the different regions does not contribute to a uniform application throughout the country. The aim of this study was to examine the norms that regulate the use of large wild game meat intended for human consumption and their applicability in hunting activities. From the comparison of the data reported in the literature and our field experience the rules implementation and the problems are evaluated. Operational procedures are then proposed to simplify some of the most difficult aspects and fill in the gaps highlighted.

2015-11-01

Full Text Available Wild species have a potential value in crop breeding. Explore MLO gene which related with powdery mildew natural resistance is very important for improving the quality of melon. Resistance to powdery mildew was examined in cultivar and wild species by leaf inoculation. The wild germplasms showed resistance to powdery mildew Race1. Cloning and sequence analysis of the CmMLO2 gene identified an 85 bp difference between the wild and cultivated species. The CmMLO2 gene was expressed in the wild germplasm after fluorescence-labeled Agrobacterium-mediated transformation. A positive transgenic plant showed successful invasion by powdery mildew Race1. These results suggested that the wild species might have failed to encode the MLO protein, thereby resulting in the MLO-negative regulation of powdery mildew, which in turn resulted in the broad-spectrum resistance of the wild species to powdery mildew.

[An overview of surveillance of avian influenza viruses in wild birds].

Zhu, Yun; Shi, Jing-Hong; Shu, Yue-Long

2014-05-01

Wild birds (mainly Anseriformes and Charadriiformes) are recognized as the natural reservoir of avian influenza viruses (AIVs). The long-term surveillance of AIVs in wild birds has been conducted in North America and Europe since 1970s. More and more surveillance data revealed that all the HA and NA subtypes of AIVs were identified in the wild ducks, shorebirds, and gulls, and the AIVs circulating in wild birds were implicated in the outbreaks of AIVs in poultry and humans. Therefore, the AIVs in wild birds pose huge threat to poultry industry and human health. To gain a better understanding of the ecology and epidemiology of AIVs in wild birds, we summarize the transmission of AIVs between wild birds, poultry, and humans, the main results of surveillance of AIVs in wild birds worldwide and methods for surveillance, and the types of samples and detection methods for AIVs in wild birds, which would be vital for the effective control of avian influenza and response to possible influenza pandemic.

As a Local Government Agencies who perform public services, General Government Office already has utilized Reporting Information System of Local Government Implementation (E-LPPD). However, E-LPPD has upgrade limitation for the integration processes that cannot accommodate General Government Offices’ needs in order to achieve Good Government Governance (GGG), while success stories of the ultimate goal of e-government implementation requires good governance practices. Currently, citizen demand public services as private sector do, which needs service innovation by utilizing the legacy system as a service based e-government implementation, while Service Oriented Architecture (SOA) to redefine a business processes as a set of IT enabled services and Enterprise Architecture from the Open Group Architecture Framework (TOGAF) as a comprehensive approach in redefining business processes as service innovation towards GGG. This paper takes a case study on Performance Evaluation of Local Government Implementation (EKPPD) system on General Government Office. The results show that TOGAF will guide the development of integrated business processes of EKPPD system that fits good governance practices to attain GGG with SOA methodology as technical approach.

The genomics of wild yeast populations sheds light on the domestication of man's best (micro) friend.

Science.gov (United States)

Eberlein, Chris; Leducq, Jean-Baptiste; Landry, Christian R

2015-11-01

The domestication of plants, animals and microbes by humans are the longest artificial evolution experiments ever performed. The study of these long-term experiments can teach us about the genomics of adaptation through the identification of the genetic bases underlying the traits favoured by humans. In laboratory evolution, the characterization of the molecular changes that evolved specifically in some lineages is straightforward because the ancestors are readily available, for instance in the freezer. However, in the case of domesticated species, the ancestor is often missing, which leads to the necessity of going back to nature in order to infer the most likely ancestral state. Significant and relatively recent examples of this approach include wolves as the closest wild relative to domestic dogs (Axelsson et al. 2013) and teosinte as the closest relative to maize (reviewed in Hake & Ross-Ibarra 2015). In both cases, the joint analysis of domesticated lineages and their wild cousins has been key in reconstructing the molecular history of their domestication. While the identification of closest wild relatives has been done for many plants and animals, these comparisons represent challenges for micro-organisms. This has been the case for the budding yeast Saccharomyces cerevisiae, whose natural ecological niche is particularly challenging to define. For centuries, this unicellular fungus has been the cellular factory for wine, beer and bread crafting, and currently for bioethanol and drug production. While the recent development of genomics has lead to the identification of many genetic elements associated with important wine characteristics, the historical origin of some of the domesticated wine strains has remained elusive due to the lack of knowledge of their close wild relatives. In this issue of Molecular Ecology, Almeida et al. (2015) identified what is to date the closest known wild population of the wine yeast. This population is found associated with

Sustainable governance of scarce metals: The case of lithium

International Nuclear Information System (INIS)

Prior, Timothy; Wäger, Patrick A.; Stamp, Anna; Widmer, Rolf; Giurco, Damien

2013-01-01

Minerals and metals are finite resources, and recent evidence suggests that for many, primary production is becoming more difficult and more expensive. Yet these resources are fundamentally important for society—they support many critical services like infrastructure, telecommunications and energy generation. A continued reliance on minerals and metals as service providers in modern society requires dedicated and concerted governance in relation to production, use, reuse and recycling. Lithium provides a good example to explore possible sustainable governance strategies. Lithium is a geochemically scarce metal (being found in a wide range of natural systems, but in low concentrations that are difficult to extract), yet recent studies suggest increasing future demand, particularly to supply the lithium in lithium-ion batteries, which are used in a wide variety of modern personal and commercial technologies. This paper explores interventions for sustainable governance and handling of lithium for two different supply and demand contexts: Australia as a net lithium producer and Switzerland as a net lithium consumer. It focuses particularly on possible nation-specific issues for sustainable governance in these two countries' contexts, and links these to the global lithium supply chain and demand scenarios. The article concludes that innovative business models, like ‘servicizing’ the lithium value chain, would hold sustainable governance advantages for both producer and consumer countries. - Highlights: • Lithium is a geochemically scare metal, but demand is forecast to increase in future • We explore sustainable lithium governance implications for Australia and Switzerland • One governance mechanism is the ‘servicization’ of the lithium value chain • We explore one actual, and two hypothetical lithium service business models • ‘Servicizing’ a commodity would require fundamental innovations in minerals policy

Community and species-specific responses of wild bees to insect pest control programs applied to a pollinator-dependent crop.

Science.gov (United States)

Tuell, Julianna K; Isaacs, Rufus

2010-06-01

Wild bee conservation is regarded as essential for sustainable production of pollinator-dependent crops, yet little is known about the effects on wild bee communities of typical insect pest management programs used postbloom. We developed an insecticide program risk (IPR) index to quantify the relative risk to wild bees of insecticide programs applied to blueberry fields. This was used to determine the relationship between IPR and the abundance, diversity, and richness of wild bee communities sampled during three successive flowering seasons. In 2 of 3 yr, bee abundance and species richness declined with increasing IPR. Bee diversity declined with IPR in one of 3 yr. These results indicate that wild bee communities are negatively affected by increasingly intensive chemical pest management activities in crop fields and that interyear variability in bee populations has the potential to mask such effects in short-term studies. When several wild bee species were analyzed separately, two of three solitary and one of three social blueberry-foraging species declined with increasing IPR values, suggesting that different life histories and nesting habits may help some bee populations escape the negative effects of insecticides applied after bloom. Pollinator conservation programs aimed strictly at reducing insecticide use may have varying success, depending on the biology of the target bee species. The IPR index provides a standard method to compare pest management programs for their potential effect on wild bee communities, with broad application for use in other agricultural systems.

Distribution of Wild and Cultivated Grapes in Turkey

Directory of Open Access Journals (Sweden)

Ibrahim H UZUN

2010-12-01

Full Text Available Turkey is one of main gene centers in the world for grapes. It is believed that cultivated grapes have their origins in Turkey and the surrounding countries. Vitis vinifera ssp sylvestris is the only wild grape species in this region. That is why Turkey has a very large amount of wild grapevine populations and grape cultivars which offer to grapevine breeders a valuable gene pool. Wild grapevines have significant characters for inducing the resistence to biotic and abiotic stress factors, such as resistance to lime, drought, pests and diseases. Turkey has over 1.600 local grape cultivars, among which the majority of them are conserved at the national grape collection vineyard in Tekirda?. They are mostly used as table grapes, dried grapes or for local consumptions. Wild grapes are distributed all over the country territory, mainly in the river basins and forests. Wild grape collection vineyards were established at some universities in Turkey. These grapevines will be screened for the resistance to biotic and abiotic stress factors.

Full Text Available This paper is an ethnobotanical review of wild edible plants gathered for consumption from the 19th century to the present day, within the present borders of Slovakia. Twenty-four sources (mainly ethnographic documenting the culinary use of wild plants were analysed. The use of 106 species (over 3% of the Slovak flora has been recorded. Nowadays most of them are no longer used, or used rarely, apart from a few species of wild fruits. The most frequently used plants include the fruits of Rubus idaeus, Fragaria spp., Rubus subgenus Rubus, Vaccinium myrtillus, V. vitis-idaea, Fagus sylvatica, Corylus avellana, Prunus spinosa, Pyrus spp., Malus spp., Crataegus spp. and the leaves of Urtica dioica, Rumex acetosa, Chenopodiaceae species, Cardamine amara, Glechoma spp., Taraxacum spp. and Oxalis acetosella. The most commonly used wild food taxa are nearly identical to those used in Poland, and the same negative association of wild vegetables with famine exists in Slovakia, resulting in their near complete disappearance from the present-day diet.

Mean concentrations of 25-hydroxyvitamin D were 554 nmol/L (222 ng/ml) with a range of 250-1,118 nmol/L (100-448 ng/ml) for wild Ricord's iguanas, 332 nmol/L (133 ng/ml) with a range of 260-369 nmol/L (104-148 ng/ml) for wild rhinoceros iguanas, and 317 nmol/L (127 ng/ml) with a range of 220-519 nmol/L (88-208 ng/ml) for captive rhinoceros iguanas. On the basis of these results, serum concentrations of at least 325 nmol/L (130 ng/ml) for 25-hydroxyvitamin D should be considered normal for healthy Ricord's and rhinoceros iguanas.

Sustainable governance of scarce metals: the case of lithium.

Minerals and metals are finite resources, and recent evidence suggests that for many, primary production is becoming more difficult and more expensive. Yet these resources are fundamentally important for society--they support many critical services like infrastructure, telecommunications and energy generation. A continued reliance on minerals and metals as service providers in modern society requires dedicated and concerted governance in relation to production, use, reuse and recycling. Lithium provides a good example to explore possible sustainable governance strategies. Lithium is a geochemically scarce metal (being found in a wide range of natural systems, but in low concentrations that are difficult to extract), yet recent studies suggest increasing future demand, particularly to supply the lithium in lithium-ion batteries, which are used in a wide variety of modern personal and commercial technologies. This paper explores interventions for sustainable governance and handling of lithium for two different supply and demand contexts: Australia as a net lithium producer and Switzerland as a net lithium consumer. It focuses particularly on possible nation-specific issues for sustainable governance in these two countries' contexts, and links these to the global lithium supply chain and demand scenarios. The article concludes that innovative business models, like 'servicizing' the lithium value chain, would hold sustainable governance advantages for both producer and consumer countries.

Wild pollinators supply essential, historically undervalued pollination services to crops and other flowering plant communities with great potential to ensure agricultural production against the loss of heavily relied upon managed pollinators. Local plant communities provision wild bees with crucial floral and nesting resources, but the distribution of floristic diversity among habitat types in North American agricultural landscapes and its effect on pollinators are diverse and poorly understood, especially in orchard systems. We documented floristic diversity in typical mid-Atlantic commercial apple (Malus domestica Borkh.) orchards including the forest and orchard-forest edge ("edge") habitats surrounding orchards in a heterogeneous landscape in south-central Pennsylvania, USA. We also assessed the correlation between plant richness and orchard pollinator communities. In this apple production region, edge habitats are the most species rich, supporting 146 out of 202 plant species recorded in our survey. Plant species richness in the orchard and edge habitats were significant predictors of bee species richness and abundance in the orchard, as well as landscape area of the forest and edge habitats. Both the quantity and quality of forest and edges close to orchards play a significant role in provisioning a diverse wild bee community in this agroecosystem. © The Authors 2015.

2010-05-30

Animal feed often contains probiotic Bacillus strains used as feed additives. Spores of the non-pathogenic B. cereus var. toyoi (product name Toyocerin) are used. Distinguishing between toxic wild-type Bacillus cereus strains and this probiotic strain is essential for evaluating the quality and risk of feed. Bacillus cereus CIP 5832 (product name Paciflor was used as probiotic strain until 2001. The properties of the two probiotic strains are quite similar. Differentiating between probiotic strains and wild-type B. cereus strains is not easy. ss-lactam antibiotics such as penicillin and cefamandole exhibit an inhibition zone in the agar diffusion test of probiotic B. cereus strains which are not seen for wild-type strains. Therefore, performing the agar diffusion test first may make sense before FT-IR testing. When randomly checking these strains by Fourier transform infrared spectroscopy (FT-IR), the probiotic B. cereus strains were separated from wild-type B. cereus/B. thuringiensis/B. mycoides/B. weihenstephanensis strains by means of hierarchical cluster analysis. The discriminatory information was contained in the spectral windows 3000-2800 cm(-1) ("fatty acid region"), 1200-900 cm(-1) ("carbohydrate region") and 900-700 cm(-1) ("fingerprint region"). It is concluded that FT-IR spectroscopy can be used for the rapid quality control and risk analysis of animal feed containing probiotic B. cereus strains. (c) 2010 Elsevier B.V. All rights reserved.

Food policy interventions are an important component of obesity-prevention strategies and can potentially drive positive changes in obesogenic environments. This study sought to identify regulatory interventions targeting the food environment, and barriers/facilitators to their implementation at the Australian state government level. In-depth interviews were conducted with senior representatives from state/territory governments, statutory authorities and non-government organizations (n =45) to examine participants' (i) suggestions for regulatory interventions for healthier food environments and (ii) support for pre-selected regulatory interventions derived from a literature review. Data were analysed using thematic and constant comparative analyses. Interventions commonly suggested by participants were regulating unhealthy food marketing; limiting the density of fast food outlets; pricing reforms to decrease fruit/vegetable prices and increase unhealthy food prices; and improved food labelling. The most commonly supported pre-selected interventions were related to food marketing and service. Primary production and retail sector interventions were least supported. The dominant themes were the need for whole-of-government and collaborative approaches; the influence of the food industry; conflicting policies/agenda; regulatory challenges; the need for evidence of effectiveness; and economic disincentives. While interventions such as public sector healthy food service policies were supported by participants, marketing restrictions and fiscal interventions face substantial barriers including a push for deregulation and private sector opposition. © 2011 The Authors. obesity reviews © 2011 International Association for the Study of Obesity.

Comparative transcriptome profiling of two Tibetan wild barley genotypes in responses to low potassium.

Directory of Open Access Journals (Sweden)

Jianbin Zeng

Full Text Available Potassium (K deficiency is one of the major factors affecting crop growth and productivity. Development of low-K tolerant crops is an effective approach to solve the nutritional deficiency in agricultural production. Tibetan annual wild barley is rich in genetic diversity and can grow normally under poor soils, including low-K supply. However, the molecular mechanism about low K tolerance is still poorly understood. In this study, Illumina RNA-Sequencing was performed using two Tibetan wild barley genotypes differing in low K tolerance (XZ153, tolerant and XZ141, sensitive, to determine the genotypic difference in transcriptome profiling. We identified a total of 692 differentially expressed genes (DEGs in two genotypes at 6 h and 48 h after low-K treatment, including transcription factors, transporters and kinases, oxidative stress and hormone signaling related genes. Meanwhile, 294 low-K tolerant associated DEGs were assigned to transporter and antioxidant activities, stimulus response, and other gene ontology (GO, which were mainly involved in starch and sucrose metabolism, lipid metabolism and ethylene biosynthesis. Finally, a hypothetical model of low-K tolerance mechanism in XZ153 was presented. It may be concluded that wild barley accession XZ153 has a higher capability of K absorption and use efficiency than XZ141 under low K stress. A rapid response to low K stress in XZ153 is attributed to its more K uptake and accumulation in plants, resulting in higher low K tolerance. The ethylene response pathway may account for the genotypic difference in low-K tolerance.

2010-12-01

Full Text Available The present investigation deals with the kinetics of submerged extracellular lipases fermentation by both wild and mutant strains of Rhizopus oligosporus var. microsporus in a laboratory scale stirred fermentor. Other parameters studied were inoculum size, pH, agitation and rate of aeration. It was found that the growth and lipases production was increased gradually and reached its maximum 9.07± 0.42ª U mL-1 (W and 42.49 ± 3.91ª U mL-1 (M after 30h of fermentation for both wild and mutant strain. There is overall increase of 109% (W and 124% (M in the production of extracellular lipases as compared to shake flask. Another significant finding of the present study is that the fermentation period is reduced to 30 h in case of wild and 23 h in case of mutant from 48 h in shake flask studies. The specific productivity of mutant strain (qp = 377.3 U/g cells/h was several folds higher than wild strain. The specific production rate and growth coefficient revealed the hyperproducibility of extracellular lipases using mutant IIB-63NTG-7.

WILD PIGS: BIOLOGY, DAMAGE, CONTROL TECHINQUES AND MANAGEMENT

Energy Technology Data Exchange (ETDEWEB)

Mayer, John; Brisbin, I. Lehr

2009-12-31

The existence of problems with wild pigs (Sus scrofa) is nothing new to the Western Hemisphere. Damage by these introduced animals was reported as far back as 1505 by the early Spanish colonies in the Caribbean, where wild pigs were killing the colonists cattle. Droves of these animals also ravaged cultivated crops of maize and sugarcane on islands in the West Indies during this same time period. These wild pigs reportedly were very aggressive and often attacked Spanish soldiers hunting rebellious Indians or escaped slaves on these islands, especially when these animals were cornered. The documentation of such impacts by introduced populations of this species in the United States has subsequently increased in recent years, and continued up through the present (Towne and Wentworth. 1950, Wood and Barrett 1979, Mayer and Brisbin 1991, Dickson et al. 2001). In spite of a fairly constant history in this country since the early 1900s, wild pigs have had a dramatic recent increase in both distribution and numbers in the United States. Between 1989 and 2009, the number of states reporting the presence of introduced wild pigs went from 19 up to as many as 44. This increase, in part natural, but largely manmade, has caused an increased workload and cost for land and resource managers in areas where these new populations are found. This is the direct result of the damage that these introduced animals do. The cost of both these impacts and control efforts has been estimated to exceed a billion dollars annually (Pimentel 2007). The complexity of this problem has been further complicated by the widespread appeal and economic potential of these animals as a big game species (Tisdell 1982, Degner 1989). Wild pigs are a controversial problem that is not going away and will likely only get worse with time. Not only do they cause damage, but wild pigs are also survivors. They reproduce at a rate faster than any other mammal of comparable size, native or introduced; they can eat just

Witkowska, Anna M; Zujko, Małgorzata E; Mirończuk-Chodakowska, Iwona

2011-01-01

The purpose of the study was to explore sixteen of the most popular edible species of wild-growing mushrooms as potential sources of antioxidants. Among the mushrooms tested, the highest total polyphenol contents, exceeding 100 mg/100 g fresh mass, were found in five mushrooms: Boletus chrysenteron, B. edulis, Leccinum scabrum, L. aurantiacum, and Macrolepiota procera. Antioxidant activity was measured with the FRAP, TEAC, DPPH scavenging ability and ferrous ions chelating ability assays. Results of the study show that wild mushrooms vary according to their antioxidant properties. The highest FRAP potentials, exceeding 1 mmol/100 g, were found in five species ofBoletales: Boletus edulis, B. chrysenteron, Leccinum scabrum, L. aurantiacum, and Suillus grevillei. TEAC values were from 1.07 to 4.01 mmol/100 g fresh mass. High TEAC values (>2.3 mmol/100 g) were found in Leccinum scabrum, L. aurantiacum, Macrolepiota procera, Boletus chrysenteron, and B. edulis. The DPPH radical scavenging effectiveness of mushroom extracts, expressed as EC50 values, was in range 2.91-13.86 mg/mL. Scavenging ability was the highest for B. edulis and B. chrysenteron. The metal chelating ability of mushroom extracts expressed as ECso values of chelating ability on ferrous ions were from 8.02 mg/mL in Cantharellus cibarius to 12.10 mg/mL in Suillus luteus. Among the mushrooms tested, Boletus chrysenteron and B. edulis were characterized by high scores of polyphenol contents and antioxidant activity in the FRAP, TEAC, and DPPH assays. These results place these culinary species of wild-growing mushrooms among products with considerable antioxidant potential.

A walk on the wild side: Oryza species as source for rice abiotic stress tolerance.

Science.gov (United States)

Menguer, Paloma Koprovski; Sperotto, Raul Antonio; Ricachenevsky, Felipe Klein

2017-01-01

Oryza sativa, the common cultivated rice, is one of the most important crops for human consumption, but production is increasingly threatened by abiotic stresses. Although many efforts have resulted in breeding rice cultivars that are relatively tolerant to their local environments, climate changes and population increase are expected to soon call for new, fast generation of stress tolerant rice germplasm, and current within-species rice diversity might not be enough to overcome such needs. The Oryza genus contains other 23 wild species, with only Oryza glaberrima being also domesticated. Rice domestication was performed with a narrow genetic diversity, and the other Oryza species are a virtually untapped genetic resource for rice stress tolerance improvement. Here we review the origin of domesticated Oryza sativa from wild progenitors, the ecological and genomic diversity of the Oryza genus, and the stress tolerance variation observed for wild Oryza species, including the genetic basis underlying the tolerance mechanisms found. The summary provided here is important to indicate how we should move forward to unlock the full potential of these germplasms for rice improvement.

Decisions on Remanufacturing with WTP Disparity and Recycling Competition under Government Subsidies

Directory of Open Access Journals (Sweden)

Tong Shu

2017-08-01

Full Text Available Enterprises have assigned increasing importance to remanufacturing, and meanwhile, the competitiveness of remanufacturing has also become established. In this article, game theory is exploited and government subsidies for remanufacturing, consumer willingness to pay and recycling competition are considered, with a focus on a supply chain consisting of one local manufacturer and one nonlocal remanufacturer. This study attempts to investigate how nonlocal remanufacturers and local manufacturers determine whether they recycle used products and engage in remanufacturing when these factors are considered, in the hope that the results can be constructive in terms of policies and management related to enterprises and governments. As such, four situations are considered and the corresponding models are built to derive the optimal production of each enterprise in the four different situations. Numerical results under the four situations are furthercompared. The results show that consumer acceptance of remanufactured products, irrespective of whether there is competition in production and recycling of remanufactured products and whetherthe government provides subsidy for remanufacturing directly affects each enterprise, remanufacturing and the profits of the overall supply chains. Based on these factors, enterprises should adjust strategies and choose to compete or stop competing or monopolize the market. The government should define attitudes towards the market competition and supervise the changes of market competitiveness based onmarket competition and consumer acceptance of remanufactured products. This study can provide some constructive guidance for some potential nonlocal enterprises engaged in remanufacturing, and at the same time shed some light for desirable direction in some further research onremanufacturing in theory and practice.

Delivering beneficial impacts in Assistive Technology: Improving government's approach to innovation.

Society typically relies on the industrial sector to supply product and service innovations through the free market system. In some areas of free market failure deemed important to society - such as Assistive Technology - governments intervene by applying alternative innovation systems. This paper contends that governments consistently and inappropriately support an exploratory grant approach led by academia which generates knowledge in conceptual and prototype states, and instead should shift to a procurement contract approach led by industry which designs, tests and deploys commercial products and services.

Lessons from industry: one school's transformation toward "lean" curricular governance.

Stratton, Terry D; Rudy, David W; Sauer, Marlene J; Perman, Jay A; Jennings, C Darrell

2007-04-01

As medical education grapples with organizational calls for centralized curricular oversight, programs may be compelled to respond by establishing highly vertical, stacked governance structures. Although these models offer discrete advantages over the horizontal, compartmentalized structures they are designed to replace, they pose new challenges to ensuring curricular quality and the educational innovations that drive the curricula. The authors describe a hybrid quality-assurance (QA) governance structure introduced in 2003 at the University of Kentucky College of Medicine (UKCOM) that ensures centralized curricular oversight of the educational product while allowing individualized creative control over the educational process. Based on a Lean production model, this approach draws on industry experiences that strategically separate institutional accountability (management) for a quality curriculum from the decision-making processes required to ensure it (production). In so doing, the authors acknowledge general similarities and key differences between overseeing the manufacture of a complex product versus the education of a physician-emphasizing the structured, sequential, and measurable nature of each process. Further, the authors briefly trace the emergence of quality approaches in manufacturing and discuss the philosophical changes that accompany transition to an institutional governance system that relies on vigorous, robust performance measures to offer continuous feedback on curricular quality.

Ninety-three giant Queensland grouper, Epinephelus lanceolatus (Bloch), were found dead in Queensland, Australia, from 2007 to 2011. Most dead fish occurred in northern Queensland, with a peak of mortalities in Cairns in June 2008. In 2009, sick wild fish including giant sea catfish, Arius thalassinus (Rüppell), and javelin grunter, Pomadasys kaakan (Cuvier), also occurred in Cairns. In 2009 and 2010, two disease epizootics involving wild stingrays occurred at Sea World marine aquarium. Necropsy, histopathology, bacteriology and PCR determined that the cause of deaths of 12 giant Queensland grouper, three wild fish, six estuary rays, Dasyatis fluviorum (Ogilby), one mangrove whipray, Himantura granulata (Macleay), and one eastern shovelnose ray, Aptychotrema rostrata (Shaw), was Streptococcus agalactiae septicaemia. Biochemical testing of 34 S. agalactiae isolates from giant Queensland grouper, wild fish and stingrays showed all had identical biochemical profiles. The 16S rRNA gene sequences of isolates confirmed all isolates were S. agalactiae; genotyping of selected S. agalactiae isolates showed the isolates from giant Queensland grouper were serotype Ib, whereas isolates from wild fish and stingrays closely resembled serotype II. This is the first report of S. agalactiae from wild giant Queensland grouper and other wild tropical fish and stingray species in Queensland, Australia. © 2012 Blackwell Publishing Ltd and State of Queensland.

Assessing Wild Bee Biodiversity in Cranberry Agroenvironments: Influence of Natural Habitats.

Gervais, Amélie; Fournier, Valérie; Sheffield, Cory S; Chagnon, Madeleine

2017-08-01

The conservation of bee populations for pollination in agricultural landscapes has attracted a lot of recent research interest, especially for crop industries undergoing expansion to meet increased production demands. In Canada, much growth has been occurring with commercial cranberry production, a field crop which is largely dependent on bee pollination. Wild bee pollinators could be negatively impacted by losses of natural habitat surrounding cranberry fields to accommodate increased production, but growers have little insight on how to manage their lands to maximize the presence of wild bees. Here, we described a 2-yr study where bee diversity and species composition were investigated to better understand the dynamic between natural habitat and cranberry fields. Bees were sampled using pan-traps and hand netting both within cranberry fields and in one of the three adjacent natural habitat types once a week during the crop flowering period. We found that bee community composition among cranberry fields did not differ based on the respective adjacent habitat type, but fields bordered by meadows were marginally less diverse than fields bordered by forest. As one would expect, field and natural habitat communities differed in terms of species composition and species richness. There was no evidence that one type of natural habitat was more favorable for the bees than another. Future agrobiodiversity studies should simultaneously examine bee diversity comprised in both crop fields and adjacent natural environments to better understand the species dynamics essential to the preservation of pollination services. © The Authors 2017.

Minerals and metals are finite resources, and recent evidence suggests that for many, primary production is becoming more difficult and more expensive. Yet these resources are fundamentally important for society—they support many critical services like infrastructure, telecommunications and energy generation. A continued reliance on minerals and metals as service providers in modern society requires dedicated and concerted governance in relation to production, use, reuse and recycling. Lithium provides a good example to explore possible sustainable governance strategies. Lithium is a geochemically scarce metal (being found in a wide range of natural systems, but in low concentrations that are difficult to extract), yet recent studies suggest increasing future demand, particularly to supply the lithium in lithium-ion batteries, which are used in a wide variety of modern personal and commercial technologies. This paper explores interventions for sustainable governance and handling of lithium for two different supply and demand contexts: Australia as a net lithium producer and Switzerland as a net lithium consumer. It focuses particularly on possible nation-specific issues for sustainable governance in these two countries' contexts, and links these to the global lithium supply chain and demand scenarios. The article concludes that innovative business models, like ‘servicizing’ the lithium value chain, would hold sustainable governance advantages for both producer and consumer countries. - Highlights: • Lithium is a geochemically scare metal, but demand is forecast to increase in future • We explore sustainable lithium governance implications for Australia and Switzerland • One governance mechanism is the ‘servicization’ of the lithium value chain • We explore one actual, and two hypothetical lithium service business models • ‘Servicizing’ a commodity would require fundamental innovations in minerals policy.

Oxidative Stress in Wild Boars Naturally and Experimentally Infected with Mycobacterium bovis.

Directory of Open Access Journals (Sweden)

Diana Gassó

Full Text Available Reactive oxygen and nitrogen species (ROS-RNS are important defence substances involved in the immune response against pathogens. An excessive increase in ROS-RNS, however, can damage the organism causing oxidative stress (OS. The organism is able to neutralise OS by the production of antioxidant enzymes (AE; hence, tissue damage is the result of an imbalance between oxidant and antioxidant status. Though some work has been carried out in humans, there is a lack of information about the oxidant/antioxidant status in the presence of tuberculosis (TB in wild reservoirs. In the Mediterranean Basin, wild boar (Sus scrofa is the main reservoir of TB. Wild boar showing severe TB have an increased risk to Mycobacterium spp. shedding, leading to pathogen spreading and persistence. If OS is greater in these individuals, oxidant/antioxidant balance in TB-affected boars could be used as a biomarker of disease severity. The present work had a two-fold objective: i to study the effects of bovine TB on different OS biomarkers (namely superoxide dismutase (SOD, catalasa (CAT, glutathione peroxidase (GPX, glutathione reductase (GR and thiobarbituric acid reactive substances (TBARS in wild boar experimentally challenged with Mycobacterium bovis, and ii to explore the role of body weight, sex, population and season in explaining the observed variability of OS indicators in two populations of free-ranging wild boar where TB is common. For the first objective, a partial least squares regression (PLSR approach was used whereas, recursive partitioning with regression tree models (RTM were applied for the second. A negative relationship between antioxidant enzymes and bovine TB (the more severe lesions, the lower the concentration of antioxidant biomarkers was observed in experimentally infected animals.

The concerns about the impact of the nervous necrosis virus (NNV) infections in wild fish have been raised. This paper presents the results of quarterly surveys of NNV in wild and cage-reared marine fish from South China Sea. Samples of 892 wild fish belonging to 69 species and 381 cage-reared fish belonging to 11 species were collected and were detected by seminested PCR and nested PCR. In the case of seminested PCR, the positive signal was detected in 3.0% and 3.1% samples of wild and cage-reared fish, respectively. However, by nested RT-PCR, the positive signal was observed in 42.3% and 63.0% samples of wild and cage-reared fish, respectively. If the fish species were considered, the positive signal was detected in 21.7% and 72.7% species of wild and cage-reared fish by seminested PCR assay, respectively. However, by nested RT-PCR, the positive signal was observed in 65.2% and 100% species of wild and cage-reared fish, respectively. The nucleotide sequences of the nested PCR products were determined. Phylogenetic tree showed that all the obtained viral isolates belonged to the red-spotted grouper nervous necrosis virus (RGNNV) genotype. Thirty-five species of the marine fish were the new hosts of NNV. © 2014 John Wiley & Sons Ltd.

Selection of energy source and evolutionary stable strategies for power plants under financial intervention of government

2017-09-01

Currently, many socially responsible governments adopt economic incentives and deterrents to manage environmental impacts of electricity suppliers. Considering the Stackelberg leadership of the government, the government's role in the competition of power plants in an electricity market is investigated. A one-population evolutionary game model of power plants is developed to study how their production strategy depends on tariffs levied by the government. We establish that a unique evolutionary stable strategy (ESS) for the population exists. Numerical examples demonstrate that revenue maximization and environment protection policies of the government significantly affect the production ESS of competitive power plants. The results reveal that the government can introduce a green energy source as an ESS of the competitive power plants by imposing appropriate tariffs.

The Effect of Altered Soil Moisture on Hybridization Rate in a Crop-Wild System (Raphanus spp..

Directory of Open Access Journals (Sweden)

Lesley G Campbell

Full Text Available Since plant mating choices are flexible and responsive to the environment, rates of spontaneous hybridization may vary across ecological clines. Developing a robust and predictive framework for rates of plant gene flow requires assessing the role of environmental sensitivity on plant reproductive traits, relative abundance, and pollen vectors. Therefore, across a soil moisture gradient, we quantified pollinator movement, life-history trait variation, and unidirectional hybridization rates from crop (Raphanus sativus to wild (Raphanus raphanistrum radish populations. Both radish species were grown together in relatively dry (no rain, relatively wet (double rain, or control soil moisture conditions in Ohio, USA. We measured wild and crop radish life-history, phenology and pollinator visitation patterns. To quantify hybridization rates from crop-to-wild species, we used a simply inherited morphological marker to detect F1 hybrid progeny. Although crop-to-wild hybridization did not respond to watering treatments, the abundance of hybrid offspring was higher in fruits produced late in the period of phenological overlap, when both species had roughly equal numbers of open flowers. Therefore, the timing of fruit production and its relationship to flowering overlap may be more important to hybrid zone formation in Raphanus spp. than soil moisture or pollen vector movements.

Policymakers' Reflections on Water Governance Issues

Directory of Open Access Journals (Sweden)

Joyeeta Gupta

2013-03-01

Full Text Available The two cultures theory argues that policy makers and scientists have different cultures and difficulty in communicating with each other. Others argue that there is increasing co-production of knowledge. This essay aims to assess the concerns of policy makers based on our policy work, policy-related research work, and our day-to-day experiences in terms of three questions: What are the perceived major issues for water governance? What are the major challenges in the structure of the existing global water governance approach? What is the vision for improving global water governance? This essay combines views from governmental, hybrid, inter- and non-governmental policy makers. It argues that water covers so many issues, aspects, and sectors that a key challenge is whether water should be governed as a sector or as a cross-cutting issue. It looks at how this challenge plays out within the United Nations system and leads to specific goal setting, while missing an overall visionary approach and a legally binding system of governance; within the hybrid arena, where it leads to inclusive discussion but not necessarily triggering consensus decisions; within nation states, where it has led to a loss of focus and a multitude of gaps and overlaps; and within transnational cooperative projects, where it has led to multiple interpretations of what is good practice. It then identifies a series of research questions.

Full Text Available Abstract Background The role of wildlife as a brucellosis reservoir for humans and domestic livestock remains to be properly established. The aim of this work was to determine the aetiology, apparent prevalence, spatial distribution and risk factors for brucellosis transmission in several Iberian wild ungulates. Methods A multi-species indirect immunosorbent assay (iELISA using Brucella S-LPS antigen was developed. In several regions having brucellosis in livestock, individual serum samples were taken between 1999 and 2009 from 2,579 wild bovids, 6,448 wild cervids and4,454 Eurasian wild boar (Sus scrofa, and tested to assess brucellosis apparent prevalence. Strains isolated from wild boar were characterized to identify the presence of markers shared with the strains isolated from domestic pigs. Results Mean apparent prevalence below 0.5% was identified in chamois (Rupicapra pyrenaica, Iberian wild goat (Capra pyrenaica, and red deer (Cervus elaphus. Roe deer (Capreolus capreolus, fallow deer (Dama dama, mouflon (Ovis aries and Barbary sheep (Ammotragus lervia tested were seronegative. Only one red deer and one Iberian wild goat resulted positive in culture, isolating B. abortus biovar 1 and B. melitensis biovar 1, respectively. Apparent prevalence in wild boar ranged from 25% to 46% in the different regions studied, with the highest figures detected in South-Central Spain. The probability of wild boar being positive in the iELISA was also affected by age, age-by-sex interaction, sampling month, and the density of outdoor domestic pigs. A total of 104 bacterial isolates were obtained from wild boar, being all identified as B. suis biovar 2. DNA polymorphisms were similar to those found in domestic pigs. Conclusions In conclusion, brucellosis in wild boar is widespread in the Iberian Peninsula, thus representing an important threat for domestic pigs. By contrast, wild ruminants were not identified as a significant brucellosis reservoir for

Concentrations of heavy metals (As, Cd, Cr, Cu, Hg, Pb, and Zn) were determined in edible parts (muscle) of 34 marine wild fish caught from the southern sea of Korea in 2007 and 2008 in order to understand the accumulation pattern of heavy metals in wild fish and to assess the potential health risk posed by fish consumption. The highest concentrations in the muscle of 17 pelagic and 17 demersal fishes were Zn and As, respectively, while the lowest concentration in both fishes was Cd. The mean concentrations of all metals except As in wild fish were much lower than the regulatory limits for fish and fishery products applied in a number of countries. Unlike other metals, As concentration in wild fish of this study region was relatively higher than that found in other country. Estimated daily intake (EDI) of the metals was in the range of 0.05% to 22.5% of the provisional maximum tolerable daily intakes (PMTDI). Similarly, the target hazard quotient (THQ) was below 1.0 for each metal. These results imply that the consumption of the investigated wild fish do not cause significant adverse health effects.

Bee species diversity enhances productivity and stability in a perennial crop.

Shelley R Rogers

Full Text Available Wild bees provide important pollination services to agroecoystems, but the mechanisms which underlie their contribution to ecosystem functioning--and, therefore, their importance in maintaining and enhancing these services-remain unclear. We evaluated several mechanisms through which wild bees contribute to crop productivity, the stability of pollinator visitation, and the efficiency of individual pollinators in a highly bee-pollination dependent plant, highbush blueberry. We surveyed the bee community (through transect sampling and pan trapping and measured pollination of both open- and singly-visited flowers. We found that the abundance of managed honey bees, Apis mellifera, and wild-bee richness were equally important in describing resulting open pollination. Wild-bee richness was a better predictor of pollination than wild-bee abundance. We also found evidence suggesting pollinator visitation (and subsequent pollination are stabilized through the differential response of bee taxa to weather (i.e., response diversity. Variation in the individual visit efficiency of A. mellifera and the southeastern blueberry bee, Habropoda laboriosa, a wild specialist, was not associated with changes in the pollinator community. Our findings add to a growing literature that diverse pollinator communities provide more stable and productive ecosystem services.

Full Text Available When field tests of transgenic plants are precluded by practical containment concerns, manipulative experiments can detect potential consequences of crop-wild gene flow. Using topical sprays of bacterial Bacillus thuringiensis larvicide (Bt and larval additions, we measured fitness effects of reduced herbivory on Brassica rapa (wild mustard and Raphanus sativus (wild radish. These species represent different life histories among the potential recipients of Bt transgenes from Bt cole crops in the US and Asia, for which rare spontaneous crosses are expected under high exposure. Protected wild radish and wild mustard seedlings had approximately half the herbivore damage of exposed plants and 55% lower seedling mortality, resulting in 27% greater reproductive success, 14-day longer life-spans, and 118% more seeds, on average. Seed addition experiments in microcosms and in situ indicated that wild radish was more likely to spread than wild mustard in coastal grasslands.

Wild hogs (Sus scrofa) are an invasive species with destructive habits, particularly rooting and wallowing, which can directly impact agricultural crops, pasture land, and water quality. Considering wild hogs are widely dispersed across the landscape, they are extremely difficult to control. Disagreements can arise among different stakeholders over whether and how their populations should be managed. The purpose of this article was to examine Tennessee, United States landowners' attitudes toward wild hogs, to compare acceptability of control methods, and to evaluate factors significantly influencing public support for regulations to control wild hogs. Logistic regression was employed to analyze data collected from a statewide survey of rural landowners in the fall of 2015. Landowners had overwhelmingly negative attitudes towards wild hogs, and were concerned about their impact on the natural environment and rural economy. Although landowners showed support for controlling wild hogs, levels of acceptability for management options varied. Respondents favored active management and supported education and incentive-based control programs to control wild hogs. Cognitive concepts such as social and personal norms and awareness of consequences, as well as demographic characteristics, significantly predicted landowners' support for state regulations to control wild hogs in Tennessee. Findings increase our understanding of the human dimensions of wild hog management and that of other similarly invasive animals, and may guide resource managers in designing effective and socially acceptable management strategies to control wild hog populations in Tennessee and elsewhere.

A junção da economia dos custos de transação com a economia das convenções, capital social e ambiente institucional oferece uma alternativa para a avaliação dos sistemas de governança adotados pelos atores de um APL. A metodologia proposta permite avaliar a adoção de todos os tipos de governança, tanto formais quanto informais, como a cooperação em rede. Ela permite, também, considerar a importância do território como fator de criação de capital social e de convenções, o que favorece a diminuição da incerteza, característica importante das transações informais.Researches on local productive systems pass through a large divulgation in the last years and today are part of industrial development politics. The difficulty in the approach of these systems is the evaluation of the adopted governances with an efficient methodology, which considerer not only the formal relationships but also the informal ones. The use of transaction costs approach together with the convention economy, social capital and institutional environment is an alternative tool to evaluate governance systems used by members of local productive systems. The methodology allows to evaluate the adoption of all kind of governance systems, formal or informal. The methodology also enable to consider the importance of territory as a factor responsible for the creation of social capital and conventions, variables responsible for the decrease of risk, an important characteristic of transactions.

Full Text Available Some form of accountability and power structure binds all organisations. Such structures are typically referred to as the “governance” structure of the organisation. In organisations that have relatively mature project applications and methodologies in place, governance mechanisms are established on more permanent bases. With its focus on performance, results and outcomes, project governance establishes decision-making structures, as well as accountability and responsibility mechanisms in public institutions to oversee projects. As government institutions increasingly place emphasis on project applications for policy implementation and service delivery initiatives, mechanisms or structures should be established to facilitate clear interfaces between the permanent organisation and the temporary project organisation. Such mechanisms or structures should enhance the governance of projects, that is, the strategic alignment of projects, the decentralisation of decision- making powers, rapid resource allocation, and the participation of external stakeholders. The purpose of this article is to explore the concept “project governance”, and to highlight examples of project governance as applied in selected government departments in provincial and national spheres. This would enable the establishment of best practice examples and assist to develop benchmarks for effective project applications for service delivery improvement.

Carcass and meat characteristics from farm-raised and wild fallow deer (Dama dama) and red deer (Cervus elaphus): A review.

Deer species are utilised for food, hunting and other products throughout the world. Consumers are typically exposed to venison derived predominantly from both farm-raised or wild fallow (Dama dama) and red deer (Cervus elaphus). The production of venison under farm conditions, compared to the meat of deer hunted in the wild, allows for a regular supply of a consistently good meat. It is lean, tasty, and rich in proteins and minerals, with a low content of fat and cholesterol. Overall, the worldwide demand for meat is still growing, and both the potential of farming deer species and their use as meat producers have led to an increased interest in venison. The current knowledge about various factors (e.g. nutrition, age, sex, condition, season) affecting venison and game meat has significantly increased during past decades but information regarding the interaction between production system or pre- and post-slaughter handling and ultimate deer meat quality are still very limited.

Medicinal and aromatic plants are used since ancient times in folk medicine and traditional food, but also in novel pharmaceutical preparations. The controversy lies in the use of cultivated and/or wild plants presenting both advantages and disadvantages in biological, ecological but also economic terms. Herein, cultivated and wild samples of Laurus nobilis L. were chemically characterized regarding nutritional value, free sugars, organic acids, fatty acids and tocopherols. Furthermore, the antioxidant activity (scavenging activity, reducing power and lipid peroxidation inhibition) and individual phenolic profile of L. nobilis extracts and infusions were evaluated. Data showed that the wild sample gave higher nutritional contribution related to a higher content of proteins, free sugars, organic acids, PUFA and tocopherols. It also gave better PUFA/SFA and n-6/n-3 ratios. Regarding antioxidant activity and phenolic compounds, it was the cultivated sample (mostly the infusion) that showed the highest values. The present study supports the arguments defending the use of wild and cultivated medicinal and aromatic plants as both present very interesting features, whether nutritional or antioxidant, that can be an assessed by their consumption. In vitro culture could be applied to L. nobilis as a production methodology that allows combination of the benefits of wild and cultivated samples. Copyright © 2014 Elsevier Ltd.

Full Text Available Digitalization is changing society by the increased connectivity and networking that digital technologies enable, such as enhancing communication, services, and trade. Increasingly, policymakers within various national governments and international organizations such as the United Nations (UN and Organization for Economic Co-operation and Development (OECD are examining the original sustainability policy concepts applied within the Brundtland Report of 1987 through the lens of digitalization. While the growth of a digital economy may increase productivity and benefit local and global economies, digitalization also raises potential sustainability challenges pertaining to social (i.e., the benefits or costs imposed by disruptive digital technologies upon social networks and ways of life, including threats to economic sustainability and the rise of economic disparity and environmental wellbeing (i.e., natural resource stewardship and concern for future generations driven by the automation of information processing and delivery of services. Various perspectives have been raised regarding how the process of digitalization might be governed, and national governments remain at odds regarding a single best strategy to promote sustainable digitalization using the Brundtland concept to meet the development needs of the present without compromising the needs of future generations (i.e., social and environmental well-being. This paper reviews three governance strategies that countries can use in conjunction with adaptive governance to respond to digitalization sustainability threats: (i a laissez-faire, industry-driven approach; (ii a precautionary and preemptive strategy on the part of government; and (iii a stewardship and “active surveillance” approach by government agencies that reduce the risks derived from digitalization while promoting private sector innovation.

Full Text Available Corporate governance reforms are occurring in countries around the globe and potentially impacting the population of the entire planet. In developing countries, such reforms occur in a larger context that is primarily defined by previous attempts at promoting “development” and recent processes of economic globalization. In this context, corporate governance reforms (in combination with the liberalising reforms associated with economic globalization, in effect represent a new development strategy for third world countries. The most basic questions that arise with respect to this situation are what the prospects for this new development model are and whether alternatives should be considered.

Full Text Available The new growth theory establishes, among other things, that government expenditure can manipulate the economic growth of a country. This study attempts to explain whether government expenditure increases or decreases economic growth in the context of Sri Lanka. Results obtained employing a productive output series and applying an analytical framework based on second degree polynomial regression are generally consistent with previous findings: government expenditure and economic growth are positively correlated; excessive government expenditure is negatively correlated with economic growth; and investment promotes growth. In a separate section, the article examines Armey’s idea of a quadratic curve that explains the level of government expenditure in an economy and the corresponding level of economic growth [Armey, D. (1995. The Freedom Revolution. Washington, D.C.: Regnery Publishing Co.]. The findings confirm the possibility of constructing the Armey curve for Sri Lanka, and it estimates the optimal level of government expenditure to be approximately 27%. This article adds to the literature indicating that the Armey curve is a reality not only for developed economies, but also for developing economies.

Pan-European E-Government Services Architecture

Science.gov (United States)

Vitvar, Tomáš; Mocan, Adrian; Nazir, Sanaullah; Wang, Xia

E-Government has been the center of interest for public administrations, citizens and businesses, as well as software vendors for several years. E-Government enables customers and members of the public and private sectors to take advantage of automated administration processes accessible on-line. These activities involve electronic exchange of information to acquire or provide products or services, to place or receive orders, or to complete financial transactions. All such communications must be performed securely, while at the same time maintaining the privacy of involved parties. E-Government allows citizens and businesses to process requests on-line, and with minimal physical interactions with public bodies. Since a complex information support often needs to be developed incrementally, e-Government services were first available as single services in specific sectors and for specific users. While these services are being further developed and expanded to be available in more sectors and for more users, their growing number leads to requirements of total or partial automation of certain tasks, for example, discovery, selection, composition and mediation of services. In addition, extensive numbers of such services are available in different sectors, and their provisioning in complex scenarios requires a good information strategy along with a good architectural and technological basis. The main goal is to identify and define methods, standards, technologies as well as legislation to be used within the whole development process and provisioning of complex e-Government systems. In the EU, the e-Government information strategy can be seen at two levels as (1) a European strategy driven by the European Commission to enable e-Government services across the EU member states and (2) national strategies to form a national e-Government available within a particular EU member state. The initiative which aims to develop the European strategy at the EU level is called IDABC.1

Allelopathic effect of ryegrass (lolium persicum) and wild mustard (sinapis arvensis) on barley

Most crop plants and weeds have allelopathic effects and analysis of these effects on plants in crop alteration and successive planting is very important. In this research the allelopathic ability of different parts and concentrations of two weeds, Lolium Persicum (Ryegrass) and Sinapis arvensis (wild mustered), on growth characteristics of two barley varieties was studied in the greenhouse using a completely randomized design with four replications. Test factors consisted of two barley varieties (Valfajr and Rehane), three weed organs (root, stalk, leaf) and four concentrations of extracts of weed organs (25, 50, 75 and control or distilled water). After the preparation of extracts of different weed organs with different concentrations, their effect on growth characteristics of barley plant was evaluated. Finally, seedling length, rootlet length caulicle length, wet weight of seedling, dry weight of seedling were measured. Also, the above two seeds had significant effects on the two strains of barley and could influence growth characteristics of barley. Based on the results of present study, one can argue that Ryegrass (Lolium Persicum) and wild mustard (Sinapis arvensis) can strongly affect germination, growth and performance of barley through production of chemical materials with allelopathic properties, leading unfavorable growth and product yield.

A valley adjacent to the extremely species-rich temperate forest vegetation of the Taibai Nature Reserve was chosen. Eighty-two people from 5 villages took part in the study. Altogether, 159 wild food plant species and 13 fungi folk taxa were mentioned by informants. The mean number of freelisted wild foods was very high (24.8; median – 21.5. An average respondent listed many species of wild vegetables (mean – 17, me- dian – 14.5, a few wild fruits (mean – 5.9 and median – 6 and very few fungi (mean – 1.9, median – 1, which they had eaten. Over 50% of respondents mentioned gathering the young shoots or leaves of Celastrus orbiculatus, Staphylea bumalda and S. holocapra, Caryopteris divaricata, Helwingia japonica, Pteridium aquilinum, Pimpinella sp., Amaranthus spp., Matteucia struthiopteris, Allium spp., Cardamine macrophylla and Chenopodium album. Only one species of fruits (Schisandra sphenanthera and none of the mushrooms were mentioned by over half of the respondents. Although very diverse, it can be noted that the use of wild vegetables has decreased compared to the second half of the 20th century, as informants listed several plants which they had stopped using (e.g. Abelia engleriana due to the availability of cultivated vegetables and other foodstuffs. On the other hand, the collection of the most well-known wild vegetables is maintained by selling them to tourists visiting agritourist farms, and restaurants.

Bacterial tests were used to assess bacterial contamination of game meat from Japanese wild boars. The bacterial contamination of wild boar meat was less than that of domestic pork, as determined by aerobic plate counts (APC) and coliform counts. None of the meat examined in this study was contaminated by Salmonella or E. coli O-157. To detect adulteration by domestic pig meat or European wild boar meat, 46 samples of game meat sold as Japanese wild boar were examined genetically. A total of 17 samples showed genetic haplotypes of European and Asian domestic pigs in the D-loop of mitochondrial DNA (mtDNA), and 16 samples showed nuclear glucosephosphate isomerase-processed pseudogene (GPIP) genotypes of European domestic pigs. The European GPIP genotypes of these samples were confirmed by PCR-RFLP analysis. These results indicate that some game meat sold as Japanese wild boar is adulterated by cross-breeding between pigs and wild boars or by contamination with meat from domestic pigs or European wild boars.

The high outcrossing rates of wild/weedy sorghum populations in Ethiopia indicate a high potential for crop genes (including transgenes) to spread within the wild pool. Therefore, effective risk management strategies may be needed if the introgression of transgenes or other crop genes from improved cultivars into wild or ...

Governance or Governing – the Missing Link?

Directory of Open Access Journals (Sweden)

Full Text Available Governance and governing are two distinct concepts, but they intertwine. “Good governing” exercises good influence on development. “Good governance” supposes first a relationship of power focused on a series of reforms structured at three levels: the political – administrative level, the economic level, and the level of civil society. As this dimension is difficult to measure, the qualitative evaluation of the governing act raised the interest of the World Bank researchers, who elaborated and monitored the dynamics of a set of indicators, which includes six major dimensions of the governing. A retrospective concerning the image of governing in Romania during the period from 1996 to 2005 suggests a modest increase of the score: from -0.138 (1996 to 0.008 (2002; that was partially achieved based on the voice and responsibility index and on the political stability index, not on those that measure more directly the administrative performance or the integrity of the governing act. For a comparative study, we chose seven countries for the purposes of analysis (two new European Union member states: Romania and Bulgaria; two older member countries of the European Union: Slovenia and Latvia; three non-member states: Moldova, Ukraine, and Georgia, which reveal the quality of the governing from a comparative perspective. Corruption control completes the image created by the analyzed indicators. The mere formal accomplishment of commitments made in the pre-accession activity, doubled by recent internal evolutions, bring doubts about the credibility of the anticorruption reforms, as Romania continues to be considered the country with the highest CPI in the European Union. The pessimism of public opinion and the fact that only 34% of the Romanian people consider that the level of corruption will decrease in the following three years constitutes an alarm signal addressed to the governance, in view of the real reformation of the administration system

Plural Governance

Plural governance is a form of governance where a firm both makes and buys similar goods or services. Despite a widespread use of plural governance there are no transaction cost models of how plural governance affects performance. This paper reviews the literature about plural forms and proposes...... a model relating transaction cost and resource-based variables to the cost of the plural form. The model is then used to analyze when the plural form is efficient compared to alternative governance structures. We also use the model to discuss the strength of three plural form synergies....

WILD PIG ATTACKS ON HUMANS

Energy Technology Data Exchange (ETDEWEB)

Mayer, J.

2013-04-12

Attacks on humans by wild pigs (Sus scrofa) have been documented since ancient times. However, studies characterizing these incidents are lacking. In an effort to better understand this phenomenon, information was collected from 412 wild pig attacks on humans. Similar to studies of large predator attacks on humans, data came from a variety of sources. The various attacks compiled occurred in seven zoogeographic realms. Most attacks occurred within the species native range, and specifically in rural areas. The occurrence was highest during the winter months and daylight hours. Most happened under non-hunting circumstances and appeared to be unprovoked. Wounded animals were the chief cause of these attacks in hunting situations. The animals involved were typically solitary, male and large in size. The fate of the wild pigs involved in these attacks varied depending upon the circumstances, however, most escaped uninjured. Most human victims were adult males traveling on foot and alone. The most frequent outcome for these victims was physical contact/mauling. The severity of resulting injuries ranged from minor to fatal. Most of the mauled victims had injuries to only one part of their bodies, with legs/feet being the most frequent body part injured. Injuries were primarily in the form of lacerations and punctures. Fatalities were typically due to blood loss. In some cases, serious infections or toxemia resulted from the injuries. Other species (i.e., pets and livestock) were also accompanying some of the humans during these attacks. The fates of these animals varied from escaping uninjured to being killed. Frequency data on both non-hunting and hunting incidents of wild pig attacks on humans at the Savannah River Site, South Carolina, showed quantitatively that such incidents are rare.

Crop wild relatives are wild species that are closely related to crops. They are valuable as potential gene donors for crop improvement and may help to ensure food security for the future. However, they are becoming increasingly threatened in the wild and are inadequately conserved, both in situ and ex situ. Information about the conservation status and utilisation potential of crop wild relatives is diverse and dispersed, and no single agreed standard exists for representing such information; yet, this information is vital to ensure these species are effectively conserved and utilised. The European Community-funded project, European Crop Wild Relative Diversity Assessment and Conservation Forum, determined the minimum information requirements for the conservation and utilisation of crop wild relatives and created the Crop Wild Relative Information System, incorporating an eXtensible Markup Language (XML) schema to aid data sharing and exchange. Crop Wild Relative Markup Language (CWRML) was developed to represent the data necessary for crop wild relative conservation and ensure that they can be effectively utilised for crop improvement. The schema partitions data into taxon-, site-, and population-specific elements, to allow for integration with other more general conservation biology schemata which may emerge as accepted standards in the future. These elements are composed of sub-elements, which are structured in order to facilitate the use of the schema in a variety of crop wild relative conservation and use contexts. Pre-existing standards for data representation in conservation biology were reviewed and incorporated into the schema as restrictions on element data contents, where appropriate. CWRML provides a flexible data communication format for representing in situ and ex situ conservation status of individual taxa as well as their utilisation potential. The development of the schema highlights a number of instances where additional standards-development may
