The aim of this is paper is phyto-sociological assessment of the current status of forest vegetation in the National Nature Reserve Dubnik (Slovakia) towards state documented in 1965. The observed state is assigned to progressive succession, which resulted in regression of large group of light-requiring species and extinction of oak forest community Quercetum pubescenti-roboris. During the reporting period there was a shift towards mezophilest types of forest with relative homogenization of habitat conditions on the major environmental gradients. (authors)

We used the global fire detection record provided by the satellite-based Moderate Resolution Imaging Spectroradiometer (MODIS) to determine the number of fires detected inside 823 tropical and subtropical moist forest reserves and for contiguous buffer areas 5, 10, and 15 km wide. The ratio of fire detection densities (detections per square kilometer) inside reserves to their contiguous buffer areas provided an index of reserve effectiveness. Fire detection density was significantly lower inside reserves than in paired, contiguous buffer areas but varied by five orders of magnitude among reserves. The buffer: reserve detection ratio varied by up to four orders of magnitude among reserves within a single country, and median values varied by three orders of magnitude among countries. Reserves tended to be least effective at reducing fire frequency in many poorer countries and in countries beset by corruption. Countries with the most successful reserves include Costa Rica, Jamaica, Malaysia, and Taiwan and the Indonesian island of Java. Countries with the most problematic reserves include Cambodia, Guatemala, Paraguay, and Sierra Leone and the Indonesian portion of Borneo. We provide fire detection density for 3964 tropical and subtropical reserves and their buffer areas in the hope that these data will expedite further analyses that might lead to improved management of tropical reserves.

A comparison of structural characteristics and ecological factors between forest reserves and managed silver fir - Norway spruce forests in Slovenia

International Nuclear Information System (INIS)

Marinšek, A.; Diaci, J.

2011-01-01

In order to examine ecological, floristic and structural differences between the forest stands of managed and unmanaged silver fir - Norway spruce forests (Bazzanio trilobatae-Abietetum albae), twelve sample plots (25x25 m) were established in forest reserves and managed forests. Within the plots, subplots and microplots we conducted phytosociological and pedological surveys, analyses of the stand structure, natural regeneration and estimation of solar radiation. We determined that there are no significant differences in floristic composition and ecological factors between managed forest and forest reserve stands. The only variables that were significantly different were the solar radiation variables (ISF; TSF; DSF), vertical structure (cover indexes (CI)) and stand basal area. Small differences in the composition and the structure of the vegetation indicate that, as far as ecosystematic changes are concerned, managing these forests is not as significant as the soil conditions. Solar radiation had a major influence on natural regeneration. Indirect solar radiation seemed to be more important than direct solar radiation. We found a statistically significant positive correlation between silver fir and Norway spruce regeneration and indirect solar radiation and confirmed that the management of light is a significant factor in the management of regeneration. Another trend that was detected was an increase in the number of beech, which will have quite a large proportion in the upper tree layer of the next generation, especially in forest reserves

Full Text Available Both government and international donor agencies now promote the use of tourism to alleviate poverty. The Botswana government has embraced tourism as a meaningful and sustainable economic activity and diversification opportunity, which now ranks second after mining in its contribution to the country’s gross domestic product. The study reported in this paper investigates perceptions of stakeholders on the opportunities that would be created for the poor by opening up Botswana’s forest reserves for ecotourism. Data was collected through mixed methods involving in-depth interviews with government departments, traditional leaders, quasi-government organisations and the Hospitality and Tourism Association of Botswana. Focus group discussions were also held with village development committees, Chobe Enclave Conservation Trust (CECT and Kasane, Lesoma and Pandematenga Trust (KALEPA members, and a consultative national workshop of stakeholders was also held. The findings indicate that opening up forest reserves for ecotourism has the potential to alleviate poverty among the disadvantaged groups living adjacent to forest reserves through direct (employment, small- and medium-sized enterprises (SMEs, secondary (linkages/partnerships and dynamic effects (sustainable livelihoods. The study concludes by cautioning that whilst pro-poor tourism may yield short- and medium-term benefits, in keeping with sustainability objectives, participants in the programme need to be mindful of forestry encroachment and come up with strategies to ensure the sustainability of the Botswana forest reserves.

Full Text Available http://dx.doi.org/10.5902/1980509812363In order to come up with a sustainable use of forest ecosystems in Cameroon, its vegetal diversity has been inventoried; the plant potentials and the structural parameters were studied in the forest reserve of Bonepoupa. Ten non-continuous plots of 200 m² were done and the materialization of the lines was done with a topofil put at the centre of the field with ropes at 5 m each of the topofil. In addition, ninety people were interviewed in order to know the potential use of species in this region. Up to 172 individuals with Diameter at Breast Height (DBH ≥ 5 cm divided into 27 species, 25 genera and 18 families were inventoried and the coefficient of abundance-dominance was determined. The diversity index of Shannon (H’ was H’1 = 4.17 ± 0.45 with H’1max = 4.75 and the evenness was R1 = 0.88. Taking into account herbaceous species, H’ determined by the coefficient of abundance-dominance was H’2 = 4.74 ± 0.56 with H’2max = 5.70 and the evenness  was  R2 = 0.83. The  total  basal  area  was 19.69 m2/ha and the density was 860 individuals/ha. These results indicate that herbaceous significantly modifies the value of the diversity index and that forest reserve of Bonepoupa is experiencing a problem of conservation which is due to a lack of its appropriate management. The knowledge of non-timber forest products and their use as food as well as medicinal resources by local population might be helpful for the sustainable management of resources in this forest reserve.

Exploitation of forest for commercial agriculture has taken toll on wildlife species worldwide. A forest farm project with the aim of compensating the forest loss has been implemented in Kemasul Forest Reserve, of Pahang State, Malaysia through plantation of fast growing and adaptable plant species. The objective of this study is to determine the impact of this practice on diversity. The study was conducted in a long strip of forest fragment, where two study sites with different landscape matrix types were chosen; oil palm plantation (JR) and Acacia mangium plantations (CM). A total of 75 individuals from 13 species and six families were collected at both sites. The result shows forest with A. mangium plantations matrix types yield higher species diversity. There are 10 shared species that can be found at both study sites including Callosciurus notatus, Hystrix brachyura, Macaca nemestrina, and Tupaia glis. However, some species only existed at selected sites such as Leopoldamys sabanus which can only be found at JR. On the other hand, Callosciurus nigrovittatus, Viverra tangalunga and Paradoxurus hermaphroditus were only recorded at CM. Out of all individuals collected, four of them are protected species as reported by IUCN. Callosciurus nigrovittatus is listed as Near Threatened while the other three species (Maxomys rajah, Maxomys whiteheadi, and Macaca nemestrina) are Vulnerable. If conservation efforts in Kemasul Forest Reserved are neglected, these four species would be exposed to critical threats that might cause them facing extinction in the future. Mann Whitney U test shows no significant difference of distribution and species richness of small to medium-sized mammals in both study sites (U=51.5, p=0.59). This study therefore reveals that although the compensatory forest plantation initiatives yield positive effect on diversity of mammal's species, it does not necessarily provide ample food resources to the wildlife, instead it serves as important buffer

Forest conservation plays a significant role in environmental sustainability. In Mexico only 8.48 million ha of forest are used for conservation of biodiversity. Payment for Environmental Services in the Monarch Butterfly Biosphere Reserve, one of the most important national protected areas, contributes to the conservation of these forests. In the Reserve, production of rainbow trout has been important for the rural communities who need to conserve the forest cover in order to maintain the hibernation cycle of the butterfly. Aquaculture is a highly productive activity for these protected areas, since it harnesses the existing water resources. In this study, changes from 1999 to 2012 in vegetation and land-use cover in the El Lindero basin within the Reserve were evaluated in order to determine the conservation status and to consider the feasibility of aquaculture as a means of sustainable development at community level. Evaluation involved stereoscopic interpretation of digital aerial photographs from 1999 to 2012 at 1:10,000 scale, comparative analysis by orthocorrected mosaics and restitution on the mosaics. Between 1999 and 2012, forested land recovered by 28.57 ha (2.70%) at the expense of non-forested areas, although forest degradation was 3.59%. Forest density increased by 16.87%. In the 46 ha outside the Reserve, deforestation spread by 0.26%, and land use change was 0.11%. The trend towards change in forest cover is closely related to conservation programmes, particularly payment for not extracting timber, reforestation campaigns and surveillance, whose effects have been exploited for the development of rural aquaculture; this is a new way to improve the socio-economic status of the population, to avoid logging and to achieve environmental sustainability in the Reserve.

Full Text Available This study assessed ecological consequences of anthropogenic pressure on Wari-Maro Forest Reserve (WMFR. The dynamics of forest cover has been assessed using a diachronic analysis of land cover maps from the Landsat satellite images of 1986, 1995 and 2006. Structural patterns of the forest has been described using forest inventory data with twenty five 1ha plots having two 50 m x 30 m plots set up inside and positioned at the opposite corners of the leading diagonal within each 1 ha plot. Established plots allowed identifying the most targeted species in illegal logging. Plots of 0.15 ha established inside each 1 ha plot helped assessing the volume of trees from which we derived carbon stock and carbon loss using conversion and expansion factors. For the two periods 1986 to 1995 and 1995 to 2006, there was a decline in forest cover which slowed down in the second decade (0.196 %.year-1 and 0.083 %.year-1 respectively. The two vegetation types of the WMFR were mainly distinguished by Lorey's mean height (12.81 m in woodland and 12.44 m in tree-savannah. Top five targeted species in illegal logging activities were: Pterocarpus erinaceus Poir., Afzelia africana Sm., Isoberlinia spp., Anogeissus leiocarpa Guill. and Daniellia oliveri (Rolfe Hutch. & Dalziel. Results also showed mean values of carbon stock and carbon losses for the whole forest of 147.84 tons C.ha-1 and 17.57 tons C.ha-1 respectively and did not depend on vegetation type. Results from this study suggest that management strategies should focus on selectively logged species. Monitoring should also be enhanced to ensure conservation of resources of the reserve which are at high risks of extinction due to selective logging rates. Keywords: anthropogenic pressure, forest cover, structure, carbon stock, Wari-Maro forest reserve, Benin.

Full Text Available Repeated slash and burn cultivation creates wasteland with thorny shrubs, which then takes a long time to become secondary forests through serial stages of succession. Assisted natural regeneration through silvicultural management is a useful restoration method to accelerate succession. This survey evaluates the effectiveness of a simple silvicultural method for the rehabilitation of degraded lands to productive forest, thereby increasing floristic wealth. Field-based comparative analyses of floristic composition were carried out at a silviculturally managed forest (Popham Arboretum and a primary forest (Kaludiyapokuna Forest Reserve which is located in Dambulla in Sri Lanka. Floristic analysis was used to examine the effectiveness of silvicultural techniques for successful restoration of degraded forest in the dry zone. Nine 20 m × 20 m plots in each forest were enumerated and the vegetation ≥ 10 cm girth at breast height was quantitatively analyzed. Cluster analysis resulted in five distinguishable clusters (two from Popham Arboretum and three from Kaludiyapokuna Forest Reserve. Similarity indices were generated to compare the plots within and between sites. Floristic similarity was higher in forest reserve plots compared to arboretum plots. A total of 72 plant species belonging to 60 genera and 26 families were recorded from the study sites. Of the recorded species, Grewia damine and Syzygium cumini (Importance Value Index, IVI = 24 and 23 respectively were the ecologically co-dominant taxa at the Popham Arboretum. In contrast, Mischodon zeylanicus (IVI = 31, Schleichera oleosa (IVI = 25 and Diospyros ebenum (IVI = 21 were the abundant taxa in the forest reserve.

Pristine forest ecosystems provide a unique perspective for the study of plant-associated microbiota since they host a great microbial diversity. Although the Amazon forest is one of the hotspots of biodiversity around the world, few metagenomic studies described its microbial community diversity thus far. Understanding the environmental factors that can cause shifts in microbial profiles is key to improving soil health and biogeochemical cycles. Here we report a taxonomic and functional characterization of the microbiome from the rhizosphere of Brosimum guianense (Snakewood), a native tree, and bulk soil samples from a pristine Brazilian Amazon forest reserve (Cuniã), for the first time by the shotgun approach. We identified several fungi and bacteria taxon significantly enriched in forest rhizosphere compared to bulk soil samples. For archaea, the trend was the opposite, with many archaeal phylum and families being considerably more enriched in bulk soil compared to forest rhizosphere. Several fungal and bacterial decomposers like Postia placenta and Catenulispora acidiphila which help maintain healthy forest ecosystems were found enriched in our samples. Other bacterial species involved in nitrogen (Nitrobacter hamburgensis and Rhodopseudomonas palustris) and carbon cycling (Oligotropha carboxidovorans) were overrepresented in our samples indicating the importance of these metabolic pathways for the Amazon rainforest reserve soil health. Hierarchical clustering based on taxonomic similar microbial profiles grouped the forest rhizosphere samples in a distinct clade separated from bulk soil samples. Principal coordinate analysis of our samples with publicly available metagenomes from the Amazon region showed grouping into specific rhizosphere and bulk soil clusters, further indicating distinct microbial community profiles. In this work, we reported significant shifts in microbial community structure between forest rhizosphere and bulk soil samples from an Amazon

A descriptive study of species composition, community structure and biomass was conducted in compartment 107, which is a rehabilitated area at Kenaboi Forest Reserve, Jelebu, Negeri Sembilan. The objective is to determine the forest structure and species composition in a rehabilitated area of Kenaboi FR since enrichment planting had done. A sample plot of 1 hectare was censused and a total of 395 trees with diameter ≥ 5 cm DBH were recorded. A total of 285 individual trees were identified belonging to 20 families and the commonest family was Dipterocarpaceae with 193 individuals. The highest tree density per ha was Shorea acuminata at 33% followed by S. parvifolia, 10% and S. leprosula, 6%. The biggest tree was Artocarpus elasticus Reinw. ex Blume with a diameter of 101 cm. The total basal area was 34.48 m2/ha, whereby the highest basal area was between 45 - 54.9 cm DBH class that contributed 10.21 m2/ha (30%). The total biomass estimation (above ground and below ground) was 792.57 t/ha. Dipterocarpaceae contributed the highest total biomass at 545.14 t/ha with S. acuminata contributed the highest total biomass of 330.45 t/ha. This study will contribute to the knowledge of regeneration forest especially on how the ecological process restoring the biodiversity and ecosystem functioning in rehabilitated forest by practicing the enrichment planting of native species.

The dependence of local people on plant medicine from natural forests has a long tradition in Tanzania and is becoming increasingly popular among rural and urban communities due to among others increase in living costs. The study on utilization of medicinal plants for meeting heath care needs was carried out between March 2001 and March 2002 in New Dabaga Ulongambi Forest Reserve, Tanzania. The study aimed at generating necessary data for the Udzungwa Mountains Forest Management project to draft sound Joint Forest Management plans. Specific objectives of the study among others were to assess knowledge associated with utilization of medicinal plants for health care needs as well as factors associated in using plant medicines in the study area. A questionnaire survey, market survey and literature review were used to collect information. Tools used for data analysis were Statistical Packages for Social Science and content analysis. A total of 45 plant species were documented curing about 22 human diseases. Medicinal plants were readily available throughout the year and plentiful in the forest reserve. Roots and leaves were the plant parts harvested for medicinal purposes. Processing of plant medicines involved boiling, pounding, soaking in water and chewing. Distance to health facility, income level of the household and beliefs contributed to the use of plant medicines. The study concluded that medicinal plants play an important role in providing primary health care to the rural communities. It is recommended that in achieving joint forest management (JFM), villagers adjacent to the forest reserve should be sensitised on the importance of JFM through seminars, workshops, drama, school songs or video show. During the development of a joint draft management plan, villagers as an informal institution must define their priority needs of use of parts of the forest in collaboration with the Udzungwa Mountains Forest Management project.

Preliminary inventory and classification of indigenous afromontane forests on the Blyde River Canyon Nature Reserve, Mpumalanga, South Africa

2004-08-01

Full Text Available Abstract Background Mixed evergreen forests form the smallest, most widely distributed and fragmented biome in southern Africa. Within South Africa, 44% of this vegetation type has been transformed. Afromontane forest only covers 0.56 % of South Africa, yet it contains 5.35% of South Africa's plant species. Prior to this investigation of the indigenous forests on the Blyde River Canyon Nature Reserve (BRCNR, very little was known about the size, floristic composition and conservation status of the forest biome conserved within the reserve. We report here an inventory of the forest size, fragmentation, species composition and the basic floristic communities along environmental gradients. Results A total of 2111 ha of forest occurs on Blyde River Canyon Nature Reserve. The forest is fragmented, with a total of 60 forest patches recorded, varying from 0.21 ha to 567 ha in size. On average, patch size was 23 ha. Two forest communities – high altitude moist afromontane forest and low altitude dry afromontane forest – are identified. Sub-communities are recognized based on canopy development and slope, respectively. An altitudinal gradient accounts for most of the variation within the forest communities. Conclusion BRCNR has a fragmented network of small forest patches that together make up 7.3% of the reserve's surface area. These forest patches host a variety of forest-dependent trees, including some species considered rare, insufficiently known, or listed under the Red Data List of South African Plants. The fragmented nature of the relatively small forest patches accentuates the need for careful fire management and stringent alien plant control.

Deforestation in the biosphere reserves, which are key Protected Areas has negative impacts on biodiversity, climate, carbon fluxes and livelihoods. Comprehensive study of deforestation in biosphere reserves is required to assess the impact of the management effectiveness. This article assesses the changes in forest cover in various zones and protected areas of Nilgiri Biosphere Reserve, the first declared biosphere reserve in India which forms part of Western Ghats-a global biodiversity hotspot. In this study, we have mapped the forests from earliest available topographical maps and multi-temporal satellite data spanning from 1920's to 2012 period. Mapping of spatial extent of forest cover, vegetation types and land cover was carried out using visual interpretation technique. A grid cell of 1 km × 1 km was generated for time series change analysis to understand the patterns in spatial distribution of forest cover (1920-1973-1989-1999-2006-2012). The total forest area of biosphere reserve was found to be 5,806.5 km(2) (93.8 % of total geographical area) in 1920. Overall loss of forest cover was estimated as 1,423.6 km(2) (24.5 % of the total forest) with reference to 1920. Among the six Protected Areas, annual deforestation rate of >0.5 was found in Wayanad wildlife sanctuary during 1920-1973. The deforestation in Nilgiri Biosphere Reserve is mainly attributed to conversion of forests to plantations and agriculture along with submergence due to construction of dams during 1920 to 1989. Grid wise analysis indicates that 851 grids have undergone large-scale negative changes of >75 ha of forest loss during 1920-1973 while, only 15 grids have shown >75 ha loss during 1973-1989. Annual net rate of deforestation for the period of 1920 to 1973 was calculated as 0.5 followed by 0.1 for 1973 to 1989. Our analysis shows that there was large-scale deforestation before the declaration of area as biosphere reserve in 1986; however, the deforestation has drastically

There is profound interest in knowing the degree to which China's institutions are capable of protecting its natural forests and biodiversity in the face of economic and political change. China's 2 most important forest-protection policies are its National Forest Protection Program (NFPP) and its national-level nature reserves (NNRs). The NFPP was implemented in 2000 in response to deforestation-caused flooding. We undertook the first national, quantitative assessment of the NFPP and NNRs to examine whether the NFPP achieved its deforestation-reduction target and whether the NNRs deter deforestation altogether. We used MODIS data to estimate forest cover and loss across mainland China (2000-2010). We also assembled the first-ever polygon dataset for China's forested NNRs (n = 237, 74,030 km(2) in 2000) and used both conventional and covariate-matching approaches to compare deforestation rates inside and outside NNRs (2000-2010). In 2000, 1.765 million km(2) or 18.7% of mainland China was forested (12.3% with canopy cover of ≥70%)) or woodland (6.4% with canopy cover <70% and tree plus shrub cover ≥40%). By 2010, 480,203 km(2) of forest and woodland had been lost, an annual deforestation rate of 2.7%. Forest-only loss was 127,473 km(2) (1.05% annually). In the NFPP provinces, the forest-only loss rate was 0.62%, which was 3.3 times lower than in the non-NFPP provinces. Moreover, the Landsat data suggest that these loss rates are overestimates due to large MODIS pixel size. Thus, China appears to have achieved, and even exceeded, its target of reducing deforestation to 1.1% annually in the NFPP provinces. About two-thirds of China's NNRs were effective in protecting forest cover (prevented loss 4073 km(2) unmatched approach; 3148 km(2) matched approach), and within-NNR deforestation rates were higher in provinces with higher overall deforestation. Our results indicate that China's existing institutions can protect domestic forest cover. © 2015 The Authors

Why would a poor and largely pro-developmental country such as Brazil, that has so much of its territory covered in forest, adopt one of the most restrictive land use requirements in the world when it comes to cutting the forest to give way to other economic uses? We describe the evolution of legal reserve legislation in Brazil, which currently requires that 20% of the area in a property (80% in the Amazon) be left in forest or its native vegetation. This legislation was put into place in 193...

Tree Nonstructural Carbohydrate Reserves Across Eastern US Temperate Forests

Science.gov (United States)

Mantooth, J.; Dietze, M.

2015-12-01

Understanding the roles, importance, and dynamics of tree non-structural carbohydrates (NSCs) is currently an active area of research. The question of how the relationships between NSCs, growth, and mortality can be used to develop more accurate projections of forest dynamics is central to this research. To begin to address this question, we have asked an even more fundamental question: How much are trees allocating carbon to storage, in the form of NSCs, versus new growth? Ecological theory predicts that there should be trade-offs between different plant life history strategies provided that there are the carbon mass-balance constraints to enforce these trade-offs. Current data on tree NSCs lack the spatial and taxonomic extent required to properly address this question. Therefore, we established a network of forest inventory plots at ten sites across the eastern US and measured growth in adult trees using increment cores and repeat measures of diameter at breast height (DBH). Increment cores were also used to measure sapwood NSCs. We hypothesized that across the eastern US, shade tolerant species, e.g. Sugar Maple (Acer saccharum) have the largest NSC reserves and that shade intolerant species have the lowest reserves. We also hypothesized that NSC reserves increase with temperature and precipitation, as with growth, and that within species NSC reserves increase with growth rate. Initial analyses of tree NSCs indicates that trees of intermediate shade tolerance, e.g. Red Oak (Quercus rubra) have the highest concentrations of sapwood NSCs, and among the highest growth rates. Across the entire study region, NSC concentrations are positively correlated with tree size and growth rate. Within species, NSC concentrations are also positively correlated with growth rate. Across functional groups healthy individuals have significantly higher sapwood NSC concentrations than visibly stressed individuals. There are also significantly lower NSC concentrations in sapwood of

The distribution patterns and coenotic confines ofthe epiphytic lichen Lobaria pulmonaria have been studied. The factors limiting the habitat of this rare lichen species in the Kologriv Forest Nature Reserve (southern taiga subzone) have been revealed. It has been shown that L. pulmonaria is attracted to forest areas, which are less affected by humans and characterized by better light conditions than other communities. It has been found that L. pulmonaria is able to colonize trees at various ontogenetic states, beginning from virginal ones.

The spatial distribution of Hymenoptera parasitoids in a forest reserve in Central Amazonia, Manaus, AM, Brazil

Directory of Open Access Journals (Sweden)

RB. Querino

Full Text Available Parasitoids are of great importance to forest ecosystems due to their ecological role in the regulation of the population of other insects. The species richness and abundance of parasitoids in the forest canopy and understory, both on the borders and in the interior of a tropical forest reserve in Central Amazonia were investigated. For a 12-month period, specimen collections were made every 15 days from suspended traps placed in the forest canopy and in the understory strata, both on the border and in the interior of forest areas. A total of 12,835 Hymenoptera parasitoids from 23 families were acquired. Braconidae, Diapriidae, Mymaridae, Eulophidae, and Scelionidae were the most represented in the area and strata samples. The results indicate that there were no significant differences in the species richness or abundance of Hymenoptera between the forest borders and the inner forest. The data does show that the presence of Hymenoptera is significantly greater in the understory in both the border and interior areas than in the canopy (vertical stratification. Aphelinidae and Ceraphronidae were significantly associated with the inner forest, while the other seven families with the border of the reserve. The abundance of Hymenoptera parasitoids presented seasonal variations during the year related to the rainy and dry seasons.

A POLICY MIX TO PREVENT A NON-COMMONS TRAGEDY FOR COLLECTIVE FOREST RESERVES IN AGRARIAN SETTLEMENTS IN NORTHWEST MATO GROSSO

Directory of Open Access Journals (Sweden)

R.B. Davenport

Full Text Available ABSTRACT Agrarian reform settlements have recently been identified as a major contributor to ongoing deforestation in the Brazilian Amazon. Collective forest reserves were established in some settlements to thwart forest loss, but settlers usually do not recognize forest commons, opting instead for continued private accumulation through forest clearing, or a "non-commons" tragedy. Pathways toward ensuring the viability of common-pool management in settlements remain unclear. Our case study focused on two similarly sized settlements in neighboring municipalities in Northwest Mato Grosso, Brazil, each with formally designated collective forest areas. In one, deforestation shifted into the collective reserve and intensified; in the other, deforestation stabilized and the collective reserve was protected. In the latter, settlers understood their collective forest reserve as a commonly held asset, with two commercially viable settlement cooperatives involved in Brazil nut (Bertholletia excelsa extractivism and added value processing. We analyze differences between the two settlements using Elinor Ostrom's framework for analysis of socio-ecological systems, and identify the locally applied policy mix ensuring the viability of a forest commons. The study concludes that "top-down" efforts to institutionalize collective governance over remaining forests will likely fail in most settlements, without a focus on alternative livelihood opportunities synergetic with forest tenure.

Ancillary obligations as an additional obligation of a limited liability company's member

Full Text Available Ancillary obligation can be defined as an obligation of a limited liability company's member undertaken through the instrument of incorporation, which can take the form of monetary or non-monetary obligation (usually it is an obligation of a non-monetary character, which has a certain financial value and can be the object of a legally valid obligation. Ancillary obligations, as a contribution to activities of the company, are not regulated in the Law on Companies. The legal nature of this obligation is different from the obligation to make a contribution in money or in kind to a company's assets, to make additional pay-ins or from the landing of funds to the company. Ancillary obligation is an optional and additional obligation of a limited liability company's member and the obligation itself and its contents is defined in the instrument of incorporation. When a limited liability company's member undertakes an ancillary obligation this creates a distinctive relationship between the member and the company, concerning their respective obligations and the legal status of the company, as well as certain consequences derived from those obligations.

USDA Forest Service Roadless Areas: Potential Biodiversity Conservation Reserves

2003-12-01

Full Text Available In January 2001, approximately 23 x 106 ha of land in the U.S. National Forest System were slated to remain roadless and protected from timber extraction under the Final Roadless Conservation Rule. We examined the potential contributions of these areas to the conservation of biodiversity. Using GIS, we analyzed the concordance of inventoried roadless areas (IRAs with ecoregion-scale biological importance and endangered and imperiled species distributions on a scale of 1:24,000. We found that more than 25% of IRAs are located in globally or regionally outstanding ecoregions and that 77% of inventoried roadless areas have the potential to conserve threatened, endangered, or imperiled species. IRAs would increase the conservation reserve network containing these species by 156%. We further illustrate the conservation potential of IRAs by highlighting their contribution to the conservation of the grizzly bear (Ursos arctos, a wide-ranging carnivore. The area created by the addition of IRAs to the existing system of conservation reserves shows a strong concordance with grizzly bear recovery zones and habitat range. Based on these findings, we conclude that IRAs belonging to the U.S. Forest Service are one of the most important biotic areas in the nation, and that their status as roadless areas could have lasting and far-reaching effects for biodiversity conservation.

A phytosociological study on the floristic and vegetation communities of Aquilaria malaccensis was carried out in Sungai Udang Forest Reserve, Malacca, Malaysia. The main objectives of this study were to identify, characterize and classify the Aquilaria malaccensis communities which were naturally distributed in the Sungai Udang Forest Reserve. A total of 25 plots (40 m x 20 m) in size were constructed according to the line transect method. The vegetation sampling and data analysis were done. A total of 80 species belonging to 79 genera and 40 families were found from all the 25 plots in Sungai Udang Forest Reserve. The most abundant family was the Euphorbiaceae with 220 individual trees, followed by Myrtaceae and Anacardiaceae representing 212 and 197 individual trees, respectively. A community which was Aquilaria malaccensis Artocarpus rigidus community with two new sub-community known as Palaquium gutta sub-community and Barringtonia racemosa sub-community were identified on the basis of statistical and phytosociological analyses. These community and sub-community also showed preference on different geographical and environmental factors such as soils and local relief. This study is useful in providing more information on the growth response of the mixed dipterocarp forest in the development of proper forest management. (author)

Obliging children.

Science.gov (United States)

Lyons, Barry

2011-01-01

Children may sometimes undergo healthcare procedures that are not intended to improve their health status. Such interventions might include the use of young children as bone marrow donors or their enrolment in non-therapeutic research. One of the justifications used to legitimise these interventions is the premise that children have obligations to others; to their family in the case of related bone marrow transplantation, and to wider society in the case of non-therapeutic research. However, this 'obligation model' (the notion that children possess positive obligations to advance the health status of others) fails as a justificatory paradigm because it is based upon a confusion, identified by Hart, between two notions; that of 'being under an obligation to do something' and that of 'being obliged to do something'. Instead the 'obligation model' is a device employed to put a justificatory gloss upon a consequentialist decision-making process; removing the legitimising gloss allows for a more transparent look at the conflict between parental rights and an individual child's right to bodily integrity.

Hovardas, Tasos; Poirazidis, Kostas

2006-11-01

Environmental education and financial support of nature conservation are considered among the primary components of the environmentalist dimension of ecotourism. The potential of environmental education calls for enhancing visitor environmental knowledge and prompting change of visitor behavior. The present study addressed the evaluation of the environmentalist dimension of ecotourism in the Dadia Forest Reserve. The first objective of the research was to study the influence of variables determined prior to the visit, namely, visitor and visit characteristics, visitor environmental information sources, visitor pro-environmental behavior, and visitation goals, on variables determined during the visit, that is, visitor participation in and satisfaction from ecotourism activities. The second objective was to study the effect of selected variables on visitor knowledge and behavior intentions. Visitor participation in and satisfaction from ecotourism activities were primarily controlled by visit characteristics. Levels of visitor knowledge were quite satisfactory; however, coherence among knowledge items was rather loose. On the other hand, behavior intention items revealed the highest possible degree of coherence, which should be attributed to the pervasive influence of visitor satisfaction from watching birds at the Bird Observatory within the Dadia Forest Reserve. Ecotourism activities, during which the main part of environmental knowledge was offered, exerted no effect on visitor knowledge; all the same, they significantly influenced visitor behavior intentions. Overall, visitor behavior intentions revealed a considerable potential of financing environmental protection and providing voluntary work in the frame of the environmental management of the Dadia Forest Reserve.

2018-02-01

The structure of algological and mycological complexes in Al-Fe-humus podzols (Albic Podzols) under pine and birch forests of the Pasvik Reserve is characterized. The number of micromycetes is higher in more acid soils of the pine forest, while the species diversity is greater under the birch forest. The genus Penicillium includes the largest number of species. The greatest abundance and occurrence frequency are typical for Penicillium spinulosum, P. glabrum, and Trichoderma viride in pine forest and for Umbelopsis isabellina, Mucor sp., Mortierella alpina, P. glabrum, Aspergillus ustus, Trichoderma viride, and T. koningii in birch forest. Cyanobacteria-algal cenoses of the investigated soils are predominated by green algae. Soils under birch forest are distinguished by a greater diversity of algal groups due to the presence of diatoms and xanthophytes. Species of frequent occurrence are represented by Pseudococcomyxa simplex and Parietochloris alveolaris in soils of the pine forest and by Tetracystis cf. aplanospora, Halochlorella rubescens, Pseudococcomyxa simplex, Fottea stichococcoides, Klebsormidium flaccidum, Hantzschia amphioxys, Microcoleus vaginatus, and Aphanocapsa sp. in soils under birch forest

Changing Perceptions of Forest Value and Attitudes toward Management of a Recently Established Nature Reserve: A Case Study in Southwest China

Hua Yang

2015-09-01

Full Text Available Identifying the main sources of conflict and understanding the relationships between protected areas and local communities are critical to conflict resolution related to protected area management. We surveyed and assessed the perceptions of local people related to forest values of the Bulong Nature Reserve (BNR, Yunnan, China, and their attitudes toward forest management of the recently-established nature reserve. Factors influencing the differences in perceptions and attitudes were investigated. Our results indicated local residents preferred the economic value of forests, and they perceived more forest values after reserve establishment than before, especially for ecological services. Interviewees believed the value of the forests have increased, and predicted that the forest will have increased importance to their livelihoods and health in the future. Nonetheless, the majority of interviewees were dissatisfied with current reserve management. Variation in these perceptions and attitudes were related to several social variables: age, gender, education, and distance from the reserve. Embedding the findings of the present study, specifically the perceptions and attitudes of local people, into management guidelines for mitigation of potential conflicts is proposed and should help managers to achieve biodiversity-related goals. This study offers new insights related to the identification of the underlying sources of conflict in forest management and provides a better understanding of the relationship between local people and protected areas. The study also contributes to the literature on forest values of indigenous populations by examining those of remote, rural populations in China.

Forest structure, stand composition, and climate-growth response in montane forests of Jiuzhaigou National Nature Reserve, China.

Directory of Open Access Journals (Sweden)

Mark W Schwartz

Full Text Available Montane forests of western China provide an opportunity to establish baseline studies for climate change. The region is being impacted by climate change, air pollution, and significant human impacts from tourism. We analyzed forest stand structure and climate-growth relationships from Jiuzhaigou National Nature Reserve in northwestern Sichuan province, along the eastern edge of the Tibetan plateau. We conducted a survey to characterize forest stand diversity and structure in plots occurring between 2050 and 3350 m in elevation. We also evaluated seedling and sapling recruitment and tree-ring data from four conifer species to assess: 1 whether the forest appears in transition toward increased hardwood composition; 2 if conifers appear stressed by recent climate change relative to hardwoods; and 3 how growth of four dominant species responds to recent climate. Our study is complicated by clear evidence of 20(th century timber extraction. Focusing on regions lacking evidence of logging, we found a diverse suite of conifers (Pinus, Abies, Juniperus, Picea, and Larix strongly dominate the forest overstory. We found population size structures for most conifer tree species to be consistent with self-replacement and not providing evidence of shifting composition toward hardwoods. Climate-growth analyses indicate increased growth with cool temperatures in summer and fall. Warmer temperatures during the growing season could negatively impact conifer growth, indicating possible seasonal climate water deficit as a constraint on growth. In contrast, however, we found little relationship to seasonal precipitation. Projected warming does not yet have a discernible signal on trends in tree growth rates, but slower growth with warmer growing season climates suggests reduced potential future forest growth.

Full Text Available Human-wildlife conflicts from 1971-2013 in Poba Reserved Forest is presented here. Data collection included interview, records of forest department and participant observation. There is an increasing trend of human-wildlife conflict in Poba RF. Encroachment for agricultural expansion, frequent venturing into forests to collect minor forest products and livestock grazing are major causes of conflicts. Most cases of conflict occurred in forests and crop fields suggesting encroachment and venturing into animal habitat exposed human to conflict with wildlife. Pearson's correlation at 0.01 level of significance showed positive correlation between wildlife injured/killed and livestock killed/injured (0.819411 and wildlife injured/killed and property damaged (0.658009 but negative correlation between wildlife injured/killed and crop damaged (-0.04104. Crop raiding by wildlife caused considerable damage to crops and property resulting in food insecurity and economic loss to farmers; farmers also suffered economic loss due to livestock lifting by prey animals. Long years of exposure to crop and property loss and risk to life are associated with negative attitude towards wildlife. The present report will be useful in understanding the nature of conflicts and help local forest department in initiating appropriate conservation measures in Poba RF

The increasing demand for forest-derived bio-fuel may decrease the amount of dead wood and hence also the amount of available substrate for saproxylic ( = dead-wood dependent) organisms. Cut stumps constitute a large portion of dead wood in managed boreal forests. The lichen flora of such stumps has received little interest. Therefore, we investigated which lichens that occur on stumps in young (4-19 years), managed forests and analyzed how species richness and occurrence of individual species were related to stump and stand characteristics. We performed lichen inventories of 576 Norway spruce stumps in 48 forest stands in two study areas in Central Sweden, recording in total 77 lichen species. Of these, 14 were obligately lignicolous, while the remaining were generalists that also grow on bark, soil or rocks. We tested the effect of characteristics reflecting successional stage, microclimate, substrate patch size, and the species pool in the surrounding area on (1) total lichen species richness, (2) species richness of obligately lignicolous lichens and (3) the occurrence of four obligately lignicolous lichen species. The most important variables were stump age, with more species on old stumps, and study area, with similar total species richness but differences in occupancy for individual species. Responses for total lichen species richness and species richness of obligately lignicolous lichens were overall similar, indicating similar ecological requirements of these two groups. Our results indicate that species richness measurements serve as poor proxies for the responses of individual, obligately lignicolous lichen species.

The Kahikinui Forest Reserve and the adjoining Nakula Natural Area Reserve (KFR-NNAR) was established in 2011 as a conservation area on the leeward slope of Haleakalā Volcano on the island of Maui to protect unique natural features and endangered species including the Hawaiian hoary bat, Lasiurus cinereus semotus. We recorded bat vocalizations from July 2012 to November 2014 using automated echolocation detectors at 14 point locations in the KFRNNAR. Our study area included remnants of recovering mesic montane forest with interspersed grasses (1,250‒1,850 m elevation, hereafter called “forest”) and xeric subalpine shrubland plant communities (1,860‒2,800 m, hereafter called “shrubland”). Monthly detections of Hawaiian hoary bats, Lasiurus cinereus semotus, within the KFR-NNAR identified areas of high and low detection probability as well as foraging activity. Sixty per cent of all detector-nights had confirmed bat vocalizations and included detections in every month of the study. Monthly detection probability values were highest from July to November 2012; these values were significantly greater than values measured in any month thereafter. Pooled values of detection probabilities, mean pulses/night, percentage of nights with feeding activity, and acoustic detections all were greater in the recovering forest zone than corresponding values from the shrublands. Our data provide baseline levels of hoary bat echolocation activity that may be compared with future studies in the KFR-NNAR relative to success criteria for Hawaiian hoary bat habitat restoration.

Impact of mining and forest regeneration on small mammal biodiversity in the Western Region of Ghana.

Much of the terrestrial biodiversity in sub-Saharan Africa is supported by tropical rainforest. Natural resource development, particularly surface mining in the rainforest, poses great risks to the region's rich and endemic biodiversity. Here, we assessed the impact of surface mining and the success of forest rehabilitation on small mammal diversity in the Western Region of Ghana. We surveyed small mammals in the project area and two adjoining forest reserves (control sites) before the mining operation and 10 years after mine closure and forest rehabilitation (topsoil replacement and revegetation). The forest reserves recorded higher species abundance than the mining areas. Majority of the species captured in the forest reserves, including Hylomyscus alleni, Praomys tullbergi, Malacomys cansdalei, and Hybomys trivirgatus, are forest obligate species. Only one individual each of H. alleni and P. tullbergi was captured in the naturally regenerated areas (core areas of mining activities that were allowed to revegetate naturally), while 32 individuals belonging to four species (Lophuromys sikapusi, Mus musculoides, Mastomys erythroleucus, and Crocidura olivieri) were recorded in the rehabilitated areas. Our data suggested negative effects of mining on small mammal diversity and the restoration of species diversity and important ecological processes after rehabilitation of altered habitats. We strongly encourage deliberate conservation efforts, particularly the development of management plans that require the restoration of degraded land resulting from mining activities.

Role of forest conservation in lessening land degradation in a temperate region: the Monarch Butterfly Biosphere Reserve, Mexico.

With international concern about the rates of deforestation worldwide, particular attention has been paid to Latin America. Forest conservation programmes in Mexico include Payment for Environmental Services (PES), a scheme that has been successfully introduced in the Monarch Butterfly Biosphere Reserve. To seek further evidence of the role of PES in lessening land degradation processes in a temperate region, the conservation state of the Cerro Prieto ejido within the Reserve was assessed by an analysis of changes in vegetation cover and land-use between 1971 and 2013. There were no changes in the total forest surface area, but the relative proportions of the different classes of cover density had changed. In 1971, closed and semi-closed forest occupied 247.81 ha and 5.38 ha, 82.33% and 1.79% of the total area of the ejido, respectively. By 2013, closed forest had decreased to 230.38 ha (76.54% of the ejido), and semi-closed cover was 17.23 ha (5.72% of the ejido), suggesting that some semi-closed forest had achieved closed status. The final balance between forest losses and recovery was: 29.63 ha were lost, whereas 13.72 ha were recovered. Losses were mainly linked to a sanitation harvest programme to control the bark beetle Scolytus mundus. Ecotourism associated with forest conservation in the Cerro Prieto ejido has been considered by inhabitants as a focal alternative for economic development. Consequently, it is essential to develop a well-planned and solidly structured approach based on social cohesion to foster a community-led sustainable development at local level.

Full Text Available Mining in tropical countries contributes significantly to the global minerals supplies but unregulated mining activities in reserved forests is associated with destruction, loss of habitats and loss of biodiversity. This study determined the area of the Offin shelterbelt forest reserve, Ghana, degraded through illegal mining (galamsey and the impacts on the livelihoods of fringe communities. Thirty-two (32 coordinates were recorded around the peripheries of disturbed site in the reserve using hand-held Global Positioning System and were then imported into a geodatabase in ArcGIS which was used to estimate the area degraded. Data was obtained from 60 purposively sampled respondents from two communities fringing the reserve and 10 key informant interviews. Increased income (13%, employment opportunities (6.7% and increased market activities (2% were some benefits of the illegal mining activities identified by the respondents. Eight respondents associated their employment with of the advent of illegal mining activities out which 6 (70% were engaged directly in mining activities, while 2 (30% were into trading. The miners earned cash income range of US $ 2.9–22.9 daily. Within 5 years, illegal mining had degraded 2.5 km2 (4.4% of the total area of the reserve and the destruction of cocoa farms and water sources (31. Farming among respondents reduced from 90% to 76% after illegal mining. The relatively high cost (US$ 6424.1 involved in flushing out and the subsequent return of such miners poses a threat to sustainable forest management and requires a more holistic approach in tackling such a problem.

2016-01-01

Protected areas form a quintessential component of the global strategy to perpetuate tropical biodiversity within relatively undisturbed wildlands, but they are becoming increasingly isolated by rapid agricultural encroachment. Here we consider a network of 788 forest protected areas (PAs) in the world's largest tropical country to examine the degree to which they remain intact, and their responses to multiple biophysical and socioeconomic variables potentially affecting natural habitat loss under varying contexts of rural development. PAs within the complex Brazilian National System of Conservation Units (SNUC) are broken down into two main classes-strictly protected and sustainable use. Collectively, these account for 22.6% of the forest biomes within Brazil's national territory, primarily within the Amazon and the Atlantic Forest, but are widely variable in size, ecoregional representation, management strategy, and the degree to which they are threatened by human activities both within and outside reserve boundaries. In particular, we examine the variation in habitat conversion rates in both strictly protected and sustainable use reserves as a function of the internal and external human population density, and levels of land-use revenue in adjacent human-dominated landscapes. Our results show that PAs surrounded by heavily settled agro-pastoral landscapes face much greater challenges in retaining their natural vegetation, and that strictly protected areas are considerably less degraded than sustainable use reserves, which can rival levels of habitat degradation within adjacent 10-km buffer areas outside.

Collectively, these account for 22.6% of the forest biomes within Brazil’s national territory, primarily within the Amazon and the Atlantic Forest, but are widely variable in size, ecoregional representation, management strategy, and the degree to which they are threatened by human activities both within and outside reserve boundaries. In particular, we examine the variation in habitat conversion rates in both strictly protected and sustainable use reserves as a function of the internal and external human population density, and levels of land-use revenue in adjacent human-dominated landscapes. Our results show that PAs surrounded by heavily settled agro-pastoral landscapes face much greater challenges in retaining their natural vegetation, and that strictly protected areas are considerably less degraded than sustainable use reserves, which can rival levels of habitat degradation within adjacent 10-km buffer areas outside.

Sanaul Haque Mondal

2017-03-01

Full Text Available Sundarbans, the largest mangrove chunk of the world is shared between Bangladesh (62% and India (38%. The objective of this paper was to examine the spatial and temporal changes in land cover (forest cover area of Sundarbans from 1973 to 2010 using remote sensing and geographic information system (GIS tool. Normal¬ized difference vegetation index (NDVI was applied to calculate the density of vegetation of Sundarbans reserved forest (SRF. This study found that there were no major changes in total areas of SRF in the last 37 years (from 1973 to 2010 albeit changes were detected within the four land cover categories-water body, mudflat, barren land and vegetated land. During 1973 to 2010, water bodies, mudflats and barren lands increased by 0.45%, 19.69% and 14.81%, respectively, while vegetated land decreased by 4.01% during the same period. This indicated that the density of evergreen vegetation and its canopy closure decreased in Sundarbans. It was thus recommended that GIS and remote sensing based real time monitoring system be developed to identify spatial and temporal changes of land cover classes of SRF.

Danquah, S.

2009-04-01

This submission captures report on the perennial occurrence of wildfires and their accompanying effects on the inhabitants and the fringe forest communities in the Worobong Forest Reserve within the Eastern part of Ghana. Wildfire continues to be the single serious threat to the sustainable development and management of forest and wildlife resources in Ghana, thus depriving indigenous fringe forest communities of enormous socio-economic benefit of the forest. Locally, fire is used in the preparation of farm lands, tapping of palm-wine, charcoal production, honey harvesting, etc. This paper identifies some of the effects of wildfires on the indigenous communities and various interventions made to address the wildfire menace in the area of study over the years. Keywords: Wildfire, Fringe Forest Communities, Sustainable Development Resources, Socio-Economic Benefits

Overview of contractual obligations of the know-how licensor under the Macedonian Law of obligations

Nashkova Suzana

2016-01-01

Full Text Available The aim of this paper is to provide a comprehensive analysis of a part of contractual obligations of the licensor of know-how and their regulation in the Macedonian legislation. Special emphasis will be placed on two obligations that contracting parties inevitably incorporate into their agreement: the licensor's obligation to transfer the know-how and to give the necessary instructions and information for its successful utilization, and the licensor's obligation to guarantee the material and legal properties of know-how. Thus, this paper is divided into two systematic sections, focusing on each of these obligations respectively and examining the solutions contained in the Macedonian Obligation Relations Act that are applicable in the regulation of these contractual obligations.

Institutional obligation

International Nuclear Information System (INIS)

Rowan, S.S.; Berwager, S.D.

1988-01-01

The institutional obligation is to act to meet primary responsibilities in the face of risks. There are risks involved in taking action, both of a quantifiable and unquantifiable nature. This paper explores weighing the risks, choosing approaches that balance primary obligations with broader ones, and presenting ethical philosophies upon which policies and strategies are based. Federal government organizations and utilities--and Bonneville Power Administration qualifies as both--have a variety of responsibilities to the public they serve. The common responsibility is that of service; for Bonneville the primary responsibility is to serve the energy related needs. It is this primary institutional obligation, as it relates to other responsibilities--and the resulting strategy for handling indoor air quality in Bonneville's new homes program--that this paper examines

2016-02-01

Termite (Blattodea: Termitoidae) assemblages have important ecological functions and vary in structure between habitats, but have not been studied in lower subtropical forests. To examine whether differences in the richness and relative abundance of termite species and functional groups occur in lower subtropical regions, termite assemblages were sampled in Dinghushan Biosphere Reserve, China, among pine forest, pine and broad-leaved mixed forest (mixed forest), and monsoon evergreen broad-leaved forest (monsoon forest). The dominant functional group was wood-feeding termites (family Termitidae), and the mixed forest hosted the greatest richness and relative abundance. Soil-feeding termites were absent from the lower subtropical system, while humus-feeding termites were sporadically distributed in mixed forest and monsoon forest. The species richness and functional group abundance of termites in our site may be linked to the forest succession. Altitude, soil temperature, air temperature, surface air relative humidity, and litter depth were significant influences on species and functional group diversity.

Analyzing the spatial extent and distribution of forest fires is essential for sustainable forest resource management. There is no comprehensive data existing on forest fires on a regular basis in Biosphere Reserves of India. The present work have been carried out to locate and estimate the spatial extent of forest burnt areas using Resourcesat-1 data and fire frequency covering decadal fire events (2004-2013) in Similipal Biosphere Reserve. The anomalous quantity of forest burnt area was recorded during 2009 as 1,014.7 km(2). There was inconsistency in the fire susceptibility across the different vegetation types. The spatial analysis of burnt area shows that an area of 34.2 % of dry deciduous forests, followed by tree savannah, shrub savannah, and grasslands affected by fires in 2013. The analysis based on decadal time scale satellite data reveals that an area of 2,175.9 km(2) (59.6 % of total vegetation cover) has been affected by varied rate of frequency of forest fires. Fire density pattern indicates low count of burnt area patches in 2013 estimated at 1,017 and high count at 1,916 in 2004. An estimate of fire risk area over a decade identifies 12.2 km(2) is experiencing an annual fire damage. Summing the fire frequency data across the grids (each 1 km(2)) indicates 1,211 (26 %) grids are having very high disturbance regimes due to repeated fires in all the 10 years, followed by 711 grids in 9 years and 418 in 8 years and 382 in 7 years. The spatial database offers excellent opportunities to understand the ecological impact of fires on biodiversity and is helpful in formulating conservation action plans.

Misleading by Omission: Rethinking the Obligation to Inform Research Subjects about Funding Sources.

Science.gov (United States)

Manson, Neil C

2017-11-15

Informed consent requirements for medical research have expanded over the past half-century. The Declaration of Helsinki now includes an explicit positive obligation to inform subjects about funding sources. This is problematic in a number of ways and seems to oblige researchers to disclose information irrelevant to most consent decisions. It is argued here that such a problematic obligation involves an "informational fallacy." The aim in the second part of the paper is to provide a better approach to making sense of how a failure to inform about funding sources wrongs subjects: by making appeals to obligations to refrain from misleading by omission. This alternative approach-grounded in a general obligation to refrain from misleading, an obligation that is independent of informed consent-provides a basis for a norm that protects subjects' interests, without the informational fallacy. The approach developed here avoids the problems identified with the currently specified general obligation to inform about funding sources. © The Author 2017.

Forest types of the "Argentino River Valley" Natural Reserve

Directory of Open Access Journals (Sweden)

Bagnato S

2008-09-01

Full Text Available Forest classification is a fundamental target for understanding forest stand dynamics and for sustainable management strategy applications. In this paper the methodological approach of forest types, already used in other Italians region, was applied for the classification of the RNO "Argentino River Valley" (southern Apennine, Italy. This study has been organized in 4 steps: 1 bibliographic analysis and collection of the acquired knowledge; 2 preliminary verification of forest types in the field; 3 description of the different units; 4 final validation of typological units. Using this approach we have characterized 9 categories and 12 forest types units. The description of each units has been filed as cards, where information of different nature is summarized and related to the organization of the typological units, to its location, to the description of the qualitative indicators (disturbances, cohort, mortality, natural dynamic tendencies, SDT, CWD etc. and quantitative indicators (dbh, average height, current annual increment, etc., to the functioning and the current management. For a better understanding of types functioning, "sylvology models" based on the "Spatial Pattern of Relative Collective Interaction" (PSICR and on the principal characteristics influencing and characterizing forest stand dynamics (availability of resources, type and frequency of disturbances, stand development, etc. have been singled out and proposed. The "forest types map" and other maps useful for the management of forest resources have been obtained. Moreover, data collected did allow to formulate several hypotheses on sustainable management.

Transience after disturbance: Obligate species recovery dynamics depend on disturbance duration.

Science.gov (United States)

Singer, Alexander; Johst, Karin

2017-06-01

After a disturbance event, population recovery becomes an important species response that drives ecosystem dynamics. Yet, it is unclear how interspecific interactions impact species recovery from a disturbance and which role the disturbance duration (pulse or press) plays. Here, we analytically derive conditions that govern the transient recovery dynamics from disturbance of a host and its obligately dependent partner in a two-species metapopulation model. We find that, after disturbance, species recovery dynamics depend on the species' role (i.e. host or obligately dependent species) as well as the duration of disturbance. Host recovery starts immediately after the disturbance. In contrast, for obligate species, recovery depends on disturbance duration. After press disturbance, which allows dynamics to equilibrate during disturbance, obligate species immediately start to recover. Yet, after pulse disturbance, obligate species continue declining although their hosts have already begun to increase. Effectively, obligate species recovery is delayed until a necessary host threshold occupancy is reached. Obligates' delayed recovery arises solely from interspecific interactions independent of dispersal limitations, which contests previous explanations. Delayed recovery exerts a two-fold negative effect, because populations continue declining to even smaller population sizes and the phase of increased risk from demographic stochastic extinction in small populations is prolonged. We argue that delayed recovery and its determinants -species interactions and disturbance duration - have to be considered in biodiversity management. Copyright © 2017 Elsevier Inc.

Full Text Available Abstract Background An ethnomedicinal study was conducted to document medicinal plants used in the treatment of ailments in villages surrounding Kimboza forest reserve, a low land catchment forest with high number of endemic plant species. Methods Ethnobotanical interviews on medicinal plants used to treat common illnesses were conducted with the traditional medical practitioners using open-ended semi -structured questionnaires. Diseases treated, methods of preparation, use and habitat of medicinal plants were recorded. Results A total of 82 medicinal plant species belonging to 29 families were recorded during the study. The most commonly used plant families recorded were Fabaceae (29%, Euphorbiaceae (20%, Asteraceae and Moraceae (17% each and Rubiaceae (15% in that order. The most frequently utilized medicinal plant parts were leaves (41.3%, followed by roots (29.0%, bark (21.7%, seeds (5.31%, and fruits (2.6%. The study revealed that stomach ache was the condition treated with the highest percentage of medicinal plant species (15%, followed by hernia (13%, diarrhea (12, fever and wound (11% each, and coughs (10%. Majority of medicinal plant species (65.9% were collected from the wild compared to only 26.7% from cultivated land. Conclusions A rich diversity of medicinal plant species are used for treating different diseases in villages around Kimboza forest reserve, with the wild habitat being the most important reservoir for the majority of the plants. Awareness programmes on sustainable utilization and active involvement of community in conservation programmes are needed.

A Study on PolInSAR Coherence Based Regression Analysis of Forest Biomass (BARKOT Reserve Forest India), Using RADARSAT-2 Datasets

Science.gov (United States)

Singh, J.; Kumar, S.; Kushwaha, S. P. S.

2015-04-01

Forests cover 30% of the world's land surface, and are home to around 90% of the world's flora and fauna. They serve as one of the world's largest carbon sinks, absorbing 2.4 million tons of CO2 each year and storing billions more in form of biomass. Around 6 million hectares of forest is lost or changed each year and as much as a fifth of global emissions are estimated to come from deforestation. Hence accurate estimation of forest biophysical variables is necessary as it is a key parameter in determination of forest inventories, vegetation modeling and global carbon cycle. SAR Remote sensing technique is capable of providing accurate and reliable information about forest parameters. The present work aims to explore the potential of C-band Radarsat-2 Polarimetric Interferometric Synthetic Aperture Radar (PolinSAR) technique for developing a relationship between complex coherence and forest aboveground biomass (t/ha). In order to attain our objective Radarsat-2 satellite interferometric pair of 4th March 2013(master image) and 28th March 2013(slave image) were acquired for Barkot Reserve Forest, Dehradun, India. Field inventory was done for 30 plots (31.62m x 31.62m) and tree height and stem diameter were procured for each plot which were later utilized in calculation of aboveground biomass(AGB).Work emphasizes on the application of PolinSAR coherence instead of using SAR backscatter which saturates after a certain value of biomass content. Complex coherence values for different polarization channels were computed with the help of polarimetric interferometric coherence matrix. Retrieved complex coherences were investigated individually and then regression analysis was carried with the field estimated aboveground biomass. R2 value of HV+VH complex coherence component was found to be relatively higher than other polarization channel components

Fuel poverty and energy efficiency obligations – A critical assessment of the supplier obligation in the UK

International Nuclear Information System (INIS)

Rosenow, Jan; Platt, Reg; Flanagan, Brooke

2013-01-01

Energy efficiency obligations (or white certificates) are increasingly used to reduce carbon emissions. While the energy efficiency obligations were originally intended as carbon reduction and not fuel poverty policies, due to recognition of the potential for regressive outcomes they often include provisions for vulnerable and low-income customers. Intuitively, reducing carbon emissions and alleviating fuel poverty seem to be two sides of the same coin. There are, however, considerable tensions between the two when addressed through energy efficiency obligations, particularly arising from the potentially regressive impacts of rising energy prices resulting from such obligations, but also the complexity of targeting fuel poor households and the implications for deliverability. Despite those tensions, the UK government decided to use energy efficiency obligations, the supplier obligation, as the main policy for reducing fuel poverty. In light of the proposals, this paper provides an analysis of the main tensions between carbon reduction and fuel poverty alleviation within energy efficiency obligations, outlines the fuel poverty provisions of the British Supplier Obligation, assesses its rules for identifying the fuel poor, and provides a critical analysis of the planned policy changes. Based on this analysis, alternative approaches to targeting fuel poverty within future supplier obligations are proposed. - Highlights: • First comprehensive analysis of energy savings obligations and fuel poverty. • Systematic comparison of targeting efficiency of fuel poverty programmes. • Critical analysis of fuel poverty provisions in British supplier obligations. • Proposal of a new approach to targeting fuel poverty within energy savings obligations

We surveyed the small mammals of remnant mixed hardwood-coniferous cloud forest at elevations ranging from 2,100–2,300 m in the Chelemhá Cloud Forest Reserve, Alta Verapaz, Guatemala. Removal-trapping using a combination of live traps, snap traps, and pitfall traps for 6 days in January 2007 resulted in 175 captures of 15 species of marsupials, shrews, and rodents. This diversity of small mammals is the highest that we have recorded from a single locality of the 10 visited during eight field seasons in the highlands of Guatemala. Based on captures, the most abundant species in the community of small mammals is Peromyscus grandis (n = 50), followed by Handleyomys rhabdops (n = 27), Heteromys desmarestianus(n = 18), Reithrodontomys mexicanus (n = 17), Handleyomys saturatior (n = 16), Sorex veraepacis (n = 15), and Scotinomys teguina (n = 13). The remaining eight species were represented by one to five individuals.

Extractive reserves in Brazilian Amazonia

Energy Technology Data Exchange (ETDEWEB)

Fearnside, P.M (National Institute for Research in the Amazon, Manaus-Amazonas (Brazil))

1989-06-01

In 1985 an opportunity arose for maintaining tracts of Amazonian forest under sustainable use. Brazil's National Council of Rubber Tappers and the Rural Worker's Union proposed the creation of a set of reserves of a new type, called extractive reserves. The first six are being established in one of the Brazilian states most threatened by deforestatation. The creation of extractive reserves grants legal protection to forest land traditionally used by rubber tappers, Brazil-nut gatherers, and other extractivists. The term extrativismo (extractivism) in Brazil refers to removing nontimber forest products, such as latex, resins, and nuts, without felling the trees. Approximately 30 products are collected for commercial sale. Many more types of forest materials are gathered, for example as food and medicines, for the extractivists' own use. The reserve proposal is attractive for several reasons related to social problems. It allows the rubber tappers to continue their livelihood rather than be expelled by deforestation. However, it is unlikely that sufficient land will be set aside as extractive reserves to employ all the tappers. Displaced rubber tappers already swell the ranks of urban slum dwellers in Brazil's Amazonian cities, and they have become refugees to continue their profession in the forests of neighboring countries, such as Bolivia.

The relationship between family obligation and religiosity on caregiving.

Science.gov (United States)

Epps, Fayron

2014-01-01

The purpose of this study was to examine the relationship between family obligation and religiosity on the positive appraisal of caregiving among African-American, Hispanic and non-Hispanic Caucasian family caregivers of older adults. Roy's adaptation model guided formulation of the aims and study design. A cross-sectional, correlational study design was employed to examine the relationship amongst variables for the family caregiver participants. Study participants (N = 69) completed a demographic tool and four instruments the: (1) Katz index, (2) obligation scale, (3) Duke University religion index, and (4) positive appraisal of care scale. There was a significant correlation between family obligation and positive appraisal of caregiving. However, there was no relationship between the family caregiver's religiosity and positive appraisal of caregiving overall. Demographic variables were also examined to show a higher marginal mean for Hispanic primary caregivers in relation to the positive appraisal of caregiving. Future studies should consider replicating these findings in a larger sample to provide health care professionals with substantial evidence to incorporate culturally sensitive interventions aimed at promoting positive outcomes and healthy family behaviors.

Environmental zoning of a forest Pacific reserve zone located in Cordoba department, colombian Caribe

International Nuclear Information System (INIS)

Henao Sarmiento, Jesus Eugenio; Cardenas Torres, Miguel Andres; Fajardo Patino, Alirio

2008-01-01

This work includes the completion of a proposed zoning of the Zona de Reserva Forestal del Pacifico (ZRFP) in jurisdiction of the department of Cordoba, which has allowed to establish the managing trends of the natural resources that have been implemented in the municipalities of Tierralta and Valencia, where the uses of the territory have opposite characteristics with the reason of being of these lands, that were originally mainly forest areas and reserves for providing useful wood resources, as well as protective areas, that might reach in the growth of the economy of the country. The offers of zoning use of the soils by vocation and occupation proposed by the Instituto Geografico Agustin Codazzi IGAC (2002) were analyzed in detail; these are the technical foundation for the subtractions, according to the Law 2 of 1959. The work of biotic characterization focuses in the forest refuges that shelter great biodiversity wealth for the region and the department. The results of the characterization and evaluation show that there is a significant deterioration of ecosystems and ecological communities of the territory because of multiple actions performed by man along history, which, besides exploiting the environmental offer, contravene in some extensions the natural vocation of the soils. Therefore, it's important to put in consideration that given the intensity of the width and lengthwise interventions realized in the ZRFP, nowadays only some areas of natural forest remain, especially in the buffer area of the Paramillo National Park and in mountain areas bordering the department of Antioquia, which demands immediate actions of preservation and restoration.

1998-01-01

A review of the 'offset well' clause found in freehold and Crown natural gas and petroleum leases was presented. The objective was to provide lessors and lessees with a clear understanding of the rights and obligations associated with offset wells. It was noted that offset well obligations vary according to the form of lease used, the type of offsetting well, the regulatory regime and the geophysical characteristics of the producing formation. Some suggestions were made as to how current versions of the offset well clause can be amended to overcome some of the problems encountered in applying the clause to an offset horizontal well that has been drilled on adjoining lands. Failure to resolve the new issues presented by horizontal drilling technology in terms of documentation, which records respective rights and obligations on the basis of generally accepted principles, will result in large numbers of conflicts and unnecessary litigation. 144 refs., 1 fig

Correlation analysis between forest carbon stock and spectral vegetation indices in Xuan Lien Nature Reserve, Thanh Hoa, Viet Nam

Dung Nguyen, The; Kappas, Martin

2017-04-01

In the last several years, the interest in forest biomass and carbon stock estimation has increased due to its importance for forest management, modelling carbon cycle, and other ecosystem services. However, no estimates of biomass and carbon stocks of deferent forest cover types exist throughout in the Xuan Lien Nature Reserve, Thanh Hoa, Viet Nam. This study investigates the relationship between above ground carbon stock and different vegetation indices and to identify the most likely vegetation index that best correlate with forest carbon stock. The terrestrial inventory data come from 380 sample plots that were randomly sampled. Individual tree parameters such as DBH and tree height were collected to calculate the above ground volume, biomass and carbon for different forest types. The SPOT6 2013 satellite data was used in the study to obtain five vegetation indices NDVI, RDVI, MSR, RVI, and EVI. The relationships between the forest carbon stock and vegetation indices were investigated using a multiple linear regression analysis. R-square, RMSE values and cross-validation were used to measure the strength and validate the performance of the models. The methodology presented here demonstrates the possibility of estimating forest volume, biomass and carbon stock. It can also be further improved by addressing more spectral bands data and/or elevation.

COMPOSITION OF MEDIUM AND LARGE MAMMALS IN FOREST RESERVE IN THE CERRADO OF BRAZIL CENTRAL

Directory of Open Access Journals (Sweden)

Rodrigo Jose Viana Leite

Full Text Available ABSTRACT Knowledge about fauna location and distribution is very important for animal biology understanding. Conservation Units are relevant to biodiversity when considering factors such as hunting, agricultural expansion and forest fires. The conservation of native vegetation fragments under more suitable management plans, recovery areas and surveys are essential to the mammals preservation. This study aimed to survey the mammals of medium and large size of the Brasilia National Forest Area 1. To carry out this study it was performed weekly rounds in search for direct and indirect mammals traces existing at forest reserve. It is reported the presence of 27 species in the study area.

Tunay, Metin

2006-07-01

Forest road construction by bulldozers in Calabrian Pine (Pinus brutia Ten.) forests on mountainous terrain of Turkey causes considerable damage to the environment and the forest standing alongside the road. This situation obliges a study of environmentally sound road construction in Turkey. This study was carried out in 4 sample sites of Antalya Forest Directorate in steep (34-50% gradient) and very steep terrain (51-70% gradient) conditions with bulldozer and excavator machine and direct damages to forest during road construction was determined, including forest area losses and damages to downhill trees in mountainous areas. It was determined that in steep terrain when excavators were used, less forest area (22.16%) was destroyed compared to bulldozers and 26.54% less area in very steep terrain. The proportion of damage on trees where bulldozer worked was nearly twofold higher than excavator was used. The results of this research show that the environmentally sensitive techniques applied for the road construction projects are considerably superior to the traditional use of bulldozers on steep slopes. The environmentally sound forest road construction by use of excavator must be considered an appropriate and reliable solution for mountainous terrain where areas of sensitive forest ecosystems are to be opened up.

Ongoing global climate change is predicted to increase the frequency and magnitude of extreme weather events, impacting population dynamics and community structure. There is, however, a critical lack of case studies considering how climatic perturbations affect biotic interactions. Here, we document how an obligate seed dispersal mutualism was disrupted by a temporally anomalous and meteorologically extreme interlude of unseasonably frigid weather, with accompanying snowstorms, in subtropical China, during January-February 2008. Based on the analysis of 5892 fecal samples (representing six mammalian seed dispersers), this event caused a substantial disruption to the relative seed dispersal function for the raisin tree Hovenia dulcis from prestorm 6.29 (2006) and 11.47 (2007), down to 0.35 during the storm (2008). Crucially, this was due to impacts on mammalian seed dispersers and not due to a paucity of fruit, where 4.63 fruit per branch were available in January 2008, vs. 3.73 in 2006 and 3.58 in 2007. An induced dietary shift occurred among omnivorous carnivores during this event, from the consumption fruit to small mammals and birds, reducing their role in seed dispersal substantially. Induced range shift extinguished the functionality of herbivorous mammals completely, however, seed dispersal function was compensated in part by three omnivorous carnivores during poststorm years, and thus while the mutualism remained intact it was enacted by a narrower assemblage of species, rendering the system more vulnerable to extrinsic perturbations. The storm's extended effects also had anthropogenic corollaries - migrating ungulates becoming exposed to heightened levels of illegal hunting - causing long-term modification to the seed dispersal community and mutualism dynamics. Furthermore, degraded forests proved especially vulnerable to the storm's effects. Considering increasing climate variability and anthropogenic disturbance, the impacts of such massive, aberrant

Full Text Available ABSTRACT The Caatinga is an endemic and threatened dry-forest biome distributed across northern Brazil. We evaluated the conservation value of a Caatinga Natural Reserve (NR - Floresta Nacional (FLONA Contendas do Sincorá - using Scarabaeinae dung beetles as a biodiversity indicator. Specifically, we contrasted two zones impacted by two distinct intensity of selective logging that happened inside the NR until 1997. Dung beetles were collected 14 years after logging, using baited pitfall traps within three main habitats (riparian forest, regenerating Caatinga or arboreal Caatinga found in two zones (Preservation and Management Zones. A total of 1,214 individuals from 21 species were sampled. The two zones presented distinct species composition, although the habitats did not exhibit such differences. Our results indicated that the secondary areas are in a conservation status similar to arboreal Caatinga and riparian forest, 14 y after logging. Furthermore, we identified seven habitat-indicator species, two of them typical to Caatinga biome, highlighting the importance of updates in NR management plan considering the Scarabaeinae regional diversity management.

Climate change threatens health, health care, and the industries and resources upon which these depend. The growing prevalence and severity of its health consequences and economic costs are alarming health professionals and organizations as their professional obligations, grounded in the core value of health, include protecting against these harms. One means of fulfilling these obligations is to lead or support sustainability initiatives that are built upon current, reliable, accurate, and unbiased evidence and collaboratively tailored to meet specific needs and respond to specific contexts. We consider why and how health professionals and organizations should lead or support such initiatives. © 2017 American Medical Association. All Rights Reserved.

Full Text Available The review presents data on 23 rare species of the Central Forest Reserve included in the Red Data Book of the Russian Federation. The state of their populations (groups of populations is assessed. The characteristics of landscape and coenotic confinement are given. Their biological and ecological features are briefly described, and the limiting factors determining the reduction in the number of some species are indicated. Over 85 years, many species have remained their biological positions in the Reserve, and their quantity has remained stable. At the same time, species of sedentary birds (Bubo bubo, Lagopus lagopus rossicus and birds nesting in the Protected Area (representatives of the Accipitridae family are now few in number due to the changes in the main habitats and deterioration of the forage resources. It is noted that the Central Forest Reserve is the largest Protected Area in Central Russia for the rare lichens Lobaria pulmonaria and Menegazzia terebrata.

This study explored the conservation values of communally reserved forests (CRFs), which local indigenous communities deliberately preserve within their area of shifting cultivation. In the current landscape of rural Borneo, CRFs are the only option for conservation because other forested areas have already been logged or transformed into plantations. By analyzing their alpha and beta diversity, we investigated how these forests can contribute to restore regional biodiversity. Although CRFs were fragmented and some had been disturbed in the past, their tree species diversity was high and equivalent to that of primary forests. The species composition of intact forests and forests disturbed in the past did not differ clearly, which indicates that past logging was not intensive. All CRFs contained unique and endangered species, which are on the IUCN Red List, Sarawak protected plants, or both. On the other hand, the forest size structure differed between disturbed and intact CRFs, with the disturbed CRFs consisting of relatively smaller trees. Although the beta diversity among CRFs was also high, we found a high contribution of species replacement (turnover), but not of richness difference, in the total beta diversity. This suggests that all CRFs have a conservation value for restoring the overall regional biodiversity. Therefore, for maintaining the regional species diversity and endangered species, it would be suitable to design a conservation target into all CRFs.

The Public Sector and Obligation to Contract

DEFF Research Database (Denmark)

Olesen, Karsten Naundrup; Indén, Tobias

2016-01-01

The paper concerns the situation where public sector bodies are forced to enter into contracts. These obligations to contract are analysed from two angles. First, the paper offers an analysis of the reasons for imposing such obligations to contract under Swedish and Danish law. Secondly the paper...... discusses some consequences of the public entities’ obligations to contract, more specific consequences for the use of rules that usually regulate contracts and the fact that obligations to contract imposed on public entities establish a new market and at the same time the obligations deprive the entities...... of the freedom to contract which is a fundamental to market behaviour. Finally attention is drawn to the fact that obligations to contract are also imposed on private entities. The paper takes Swedish and Danish regulations as a point of departure and provides an insight into regulations from these two countries...

Palaeoecological data as a tool to predict possible future vegetation changes in the boreal forest zone of European Russia: a case study from the Central Forest Biosphere Reserve

Science.gov (United States)

Novenko, E. Yu; Tsyganov, A. N.; Olchev, A. V.

2018-01-01

New multi-proxy records (pollen, testate amoebae, and charcoal) were applied to reconstruct the vegetation dynamics in the boreal forest area of the southern part of Valdai Hills (the Central Forest Biosphere Reserve) during the Holocene. The reconstructions of the mean annual temperature and precipitation, the climate moisture index (CMI), peatland surface moisture, and fire activity have shown that climate change has a significant impact on the boreal forests of European Russia. Temperature growth and decreased moistening during the warmest phases of the Holocene Thermal Maximum in 7.0-6.2 ka BP and 6.0-5.5 ka BP and in the relatively warm phase in 3.4-2.5 ka BP led to structural changes in plant communities, specifically an increase in the abundance of broadleaf tree species in forest stands and the suppression of Picea. The frequency of forest fires was higher in that period, and it resulted in the replacement of spruce forests by secondary stands with Betula and Pinus. Despite significant changes in the climatic parameters projected for the 21st century using even the optimistic RCP2.6 scenario, the time lag between climate changes and vegetation responses makes any catastrophic vegetation disturbances (due to natural reasons) in the area in the 21st century unlikely.

Understanding the Stability of Forest Reserve Boundaries in the West Mengo Region of Uganda

Nathan D. Vogt

2006-06-01

Full Text Available Despite heavy pressure and disturbance, state property regimes have stemmed deforestation within protected areas of the West Mengo region of Uganda for over 50 yr. In this manuscript, we reconstruct the process of creation and maintenance of forest reserve boundaries in the West Mengo region of Uganda to identify why these boundaries have largely remained stable over the long term under conditions in which they may be predicted to fail. The dramatic boundary stability in West Mengo we attribute to key aspects of institutional design and enforcement of boundaries.

Chicle harvesting and extractive reserves in the Maya Biosphere b: Reserve

Energy Technology Data Exchange (ETDEWEB)

Dugelby, B.L.

1995-12-31

Chicle latex has been extracted from the forests of northern Guatemala for over 100 years and is a key element in the extractive reserve component of the Maya Biosphere Reserve. The carrying capacity of the reserve for chicle extraction can be estimated from a model incorporating ecological data (such as latex yields per tree and population structure of chicle trees, Manilkara zapota, Sapot.) with socio-ecological and political information concerning camp and chicle resource availability, harvester tapping behavior, and historical and present-day institutional organization. I estimate that chicle harvestors currently utilize and area larger than the multiple use zone of the reserve in a unsustainable manner. Simple reduction of harvestors numbers will not ensure sustainability; institutional reforms are also in order. Extractive reserves can play an important role in preserving tropical forests. However, their effectiveness is highly dependent on prevailing ecological, socio-economic, and political conditions. Wise planning and management of extractive reserves demands an understanding of the system`s carrying capacity. In addition, a strong institutional foundation is necessary to assure effective monitoring and enforcement of harvesting regulations.

Successional study for the restoration at Carpatos forest reserve in Guasca, Cundinamarca

International Nuclear Information System (INIS)

Cantillo Higuera Edgard Ernesto; Lozada Silva Alberto; Pinzon Gonzalez Julian

2009-01-01

Based on floristic and structural characterization, four stages of secondary succession were analyzed within a matrix of vegetation that had been disrupted (185 ha) at Carpatos Forest Reserve. This reserve is located in the foothills of Colombian's Eastern Mountain Range (Cordillera Oriental), among 2600 and 3000 meters above sea level, and it is aimed at making a contribution to prepare a restoration protocol. In flat, wet areas, vegetation represented by grassland whit Rubus floribundum y Pteridium aquilinum, grows up to 0.7 m height on average. It is characterized by Pteridium aquilinum, which holds an average of 1638 individuals per 0.1 ha and a total of four species with the same number of genera and families bushes of Solanum inopinum and Chusquea scandens, less than 3 m height, were dominated by Chusquea scandens, with an estimated average of 638 individuals per 0.1 ha and a total of four species and the same number of genera and families. In areas of steeper slopes and lower humidity more structured vegetation grows. This forests in recovery dominated by Miconia theaezans y Myrsine coriacea, which contains two types of vegetation: Hedyosmum crenatum y Myrsine coriacea, which are dominated by a shrub layer no taller than 5 m, with Myrsine coriacea as its most important species, and an estimated average of 1742 individuals per 0.1 ha and a total of 18 species, 16 genera and 13 families, and Weinmannia pinnata y Miconia theaezans, represented by Myrsine coriacea, Miconia theaezans and Weinmannia pinnata as important species, which held an estimated average of 1833 individuals per 0.1 ha and a total of 14 species, 12 genera and 11 families. Myrsine coriacea, Miconia theaezans, Weinmannia pinnata and Hedyosmun crenatum are regarded as the most suitable to start reproductive, adaptive and developing silvicultural protocols. Management analysis suggests that there is a correlation between higher clay content and the secondary-succession initial-state communities

Large-scale carbon stock assessment of woody vegetation in tropical dry deciduous forest of Sathanur reserve forest, Eastern Ghats, India.

Science.gov (United States)

Gandhi, Durai Sanjay; Sundarapandian, Somaiah

2017-04-01

Tropical dry forests are one of the most widely distributed ecosystems in tropics, which remain neglected in research, especially in the Eastern Ghats. Therefore, the present study was aimed to quantify the carbon storage in woody vegetation (trees and lianas) on large scale (30, 1 ha plots) in the dry deciduous forest of Sathanur reserve forest of Eastern Ghats. Biomass of adult (≥10 cm DBH) trees was estimated by species-specific allometric equations using diameter and wood density of species whereas in juvenile tree population and lianas, their respective general allometric equations were used to estimate the biomass. The fractional value 0.4453 was used to convert dry biomass into carbon in woody vegetation of tropical dry forest. The mean aboveground biomass value of juvenile tree population was 1.86 Mg/ha. The aboveground biomass of adult trees ranged from 64.81 to 624.96 Mg/ha with a mean of 245.90 Mg/ha. The mean aboveground biomass value of lianas was 7.98 Mg/ha. The total biomass of woody vegetation (adult trees + juvenile population of trees + lianas) ranged from 85.02 to 723.46 Mg/ha, with a mean value of 295.04 Mg/ha. Total carbon accumulated in woody vegetation in tropical dry deciduous forest ranged from 37.86 to 322.16 Mg/ha with a mean value of 131.38 Mg/ha. Adult trees accumulated 94.81% of woody biomass carbon followed by lianas (3.99%) and juvenile population of trees (1.20%). Albizia amara has the greatest biomass and carbon stock (58.31%) among trees except for two plots (24 and 25) where Chloroxylon swietenia contributed more to biomass and carbon stock. Similarly, Albizia amara (52.4%) showed greater carbon storage in juvenile population of trees followed by Chloroxylon swietenia (21.9%). Pterolobium hexapetalum (38.86%) showed a greater accumulation of carbon in liana species followed by Combretum albidum (33.04%). Even though, all the study plots are located within 10 km radius, they show a significant spatial variation among

DIVERSITY AND ECOLOGICAL DETERMINANTS OF DEAD WOOD FUNGI IN TREE NATURAL RESERVES OF BROAD LEAVED FORESTS FROM SUCEAVA COUNTY

Directory of Open Access Journals (Sweden)

Ciprian BÎRSAN

2014-12-01

Full Text Available Dead wood fungi have a major importance for forests biodiversity as they produce wood degradation in forest habitats. In this paper are presented some aspects related to the diversity of dead wood fungi in tree deciduous forest types from tree natural reserves (Crujana, Dragomirna and Zamostea from Suceava County and the effect of some ecological factors (host tree, diameter and decomposition degree of the dead wood and some microclimatic characteristics of sites on their occurrence and diversity. Investigations carried out in 2013 resulted in the identification of 44 lignicolous fungi species. Analysis of similarities between lingnicolous fungi species from the investigated natural reserves (by hierarchical clustering shows a separation of three fungi groups, depending on the host-trees species. The effect of the tree host species was highlighted also by detrended correspondence analysis, which, in addition presented the existence of an altitudinal gradient and a weaker effect of site conditions (slope and aspect and microclimatic variables (solar radiation on dead wood fungi occurrence. The effect of diameter and decomposition degree of fallen trunks and branches on dead wood fungi species was investigated using the redundancy analysis showing that wood debris with large surfaces are more easily colonized by the fungi species developing large sporocarps compared to small branches with low diameters colonized only by few or a single fungus species.

The economics of a landing obligation

Andersen, Peder; Ståhl, Lisa

By 2015 The European Common Fisheries Policy Reform includes a landing obligation in some fisheries and over the next few years all EU fisheries will be facing the obligation to land all catches. In spite of that, there is a lack of theoretical as well as empirical analyses of the consequences...... of a landing obligation. The paper includes an empirical analysis of the landing obligation’s impact on the Danish fishery in the short run. In the first part of the paper, we survey the fisheries economics literature for theoretical findings regarding behavioural aspects of a discard ban and we exploring gaps...... things, the analysis shows that the fisheries will suffer economic losses under the landing obligation if quotas are not increased with the historical discard rate. With quota top-ups however fisheries can experience economic gains which increase with reduced minimum sizes or by increasing selectivity....

We examined the growth, reproduction, rutting behavior, and health status of sambar deer (Cervus unicolor brookei) in secondary Acacia mangium plantation. The data were collected over 11 years from a breeding herd of 21 stags and 33 hinds in Sabal Forest Reserve, Sarawak, Malaysia. Brody's growth model of the pooled data is Y t  = 148.56 (1 - 0.98e(-0.023t)), which estimates that maximum weights of adults are 184 and 115 kg for males and females respectively. Sambar deer are nonseasonal breeders with the breeding peak in February. Although the earliest age at which a female reached sexual maturity was 11 months, the mean age was 23 ± 7 months. Mean age of first fawning was 32 ± 8 months. Mean gestation period was 259 ± 12 days (n = 82). Stags shed antlers mostly between March and July. Velvet hardens at 103 ± 27 days (n = 23), and velvet harvesting is best at 7-9 weeks when antler length is 25-30 cm. Sambar deer are suitable as a farm species in forest plantations and have a vast potential to uplift rural living standards.

Where to place the saving obligation: Energy end-users or suppliers?

International Nuclear Information System (INIS)

Bertoldi, Paolo; Labanca, Nicola; Rezessy, Silvia; Steuwer, Sibyl; Oikonomou, Vlasis

Obligations to save energy differentiate, among other features, by obliged parties. These are obligations on energy suppliers and energy end-users. Supplier obligations have been introduced in North America, Europe and Australia. Under supplier obligations energy suppliers have to comply with mandatory energy saving targets and thus they implement (directly or via third parties) energy efficiency projects on their clients’ premises, or they decide to trade certified project savings if this option is envisaged by their obligation scheme. In several emerging schemes such as the UK Carbon Reduction Commitment (CRC) Energy Efficiency Scheme, the Tokyo Emission Trading Scheme or the Perform Achieve and Trade (PAT) Scheme in India, the obligation to reduce energy consumption is placed on large end-users directly and end-users are allowed to trade emissions allowances or energy saving certificates. The paper starts with presenting these two conceptually different ways for introducing energy saving obligations. Then it analyses advantages and disadvantages of end-users obligations compared to suppliers obligations. The preliminary conclusion of the paper is that supplier obligations seem to be well-suited for the residential sector, but end-user saving obligations may offer advantages when it comes to the industrial and commercial sectors. - Highlights: • We present different ways for introducing energy saving obligations. • We analyse energy end-users obligations vs. supplier obligations. • Supplier obligations seem to be well-suited for the residential sector. • End-user obligations offer advantages in the industrial and commercial sectors

Obligation target for sustainable energy

Lensink, S.M.; Hekkenberg, M.

2012-01-01

The Dutch Ministry of Economic Affairs, Agriculture and Innovation asked ECN several questions about the development of a supplier's obligation. These questions addressed the volume of the certificates market. The questions are worded as follows by ECN: What is a realistic level to be set for the obligation for sustainable energy or for renewable electricity (in percentage of delivered electricity or TWh/year)? How far into the future should these obligations minimally be set? Is it desirable to limit the certificate issuance time to for example the economic life of an installation? This memo addresses the questions, knowing that the entire policy development process will still take considerable time. At the time of publication of this memo, large uncertainties still existed about the eventual shaping of future policy. [nl

Implementation of State Obligations and Responsibility Ensuring the Availability of Clean Water in Karimunjawa Islands

This article aims to analyze the implementation of state obligations and responsibility ensuring the availability of clean water as part of human rights in Karimunjawa islands. The analysis based on principle of the State obligations and responsibility to fulfill their citizen right. Water sources in Karimunjawa Islands is very limited. It depend on forest conservation. Around 9.600 peoples live in Karimunjawa Islands, but Karimunjawa is non groundwater basin region. It means, Karimunjawa doesn't have groundwater potential. The quantity of water depends on the season. The solution to maintain the sustainability of clean water is piping from water reservoir to residential areas. The problem is there are so many hotels in Karimunjawa islands, it disrupted the fulfillment of clean water. Besides utilizing water from reservoir, many hotels drilled the ground to get water. It had impact to the availibity of water in dry season and affected to fulfillment of water supply for Karimunjawa people. There is no specific regulation and policy to solve this problem. Clean water management is doing by Karimunjawa's people. Meanwhile, based on Mahkamah Konstitusi Decree number 85/PUU-XI/2013, state is a rights holder to dominate the water in accordance with the Articles 33 paragraph (2) and (3) UUD NRI 1945, so the government has an obligation to make a policy, regulations, management, and supervision.

Cartographic modeling of heterogeneous landscape for footprint analysis of Eddy Covariance Measurements (Central Forest and Central Chernozem reserves, Russia)

Science.gov (United States)

Kozlov, Daniil

2014-05-01

The topographical, soil and vegetation maps of FLUXNET study areas are widely used for interpretation of eddy covariance measurements, for calibration of biogeochemical models and for making regional assessments of carbon balance. The poster presents methodological problems and results of ecosystem mapping using GIS, remote sensing, statistical and field methods on the example of two RusFluxNet sites in the Central Forest (33° E, 56°30'N) and Central Chernozem (36°10' E, 51°36'N) reserves. In the Central Forest reserve tacheometric measurements were used for topographical and peat surveys of bogged sphagnum spruce forest of 20-hectare area. Its common borders and its areas affected by windfall were determined. The supplies and spatial distribution of organic matter were obtained. The datasets of groundwater monitoring measurements on ten wells were compared with each other and the analysis of spatial and temporal groundwater variability was performed. The map of typical ecosystems of the reserve and its surroundings was created on the basis of analysis of multi-temporal Landsat images. In the Central Chernozem reserve the GNSS topographical survey was used for flux tower footprint mapping (22 ha). The features of microrelief predetermine development of different soils within the footprint. Close relationship between soil (73 drilling site) and terrain attributes (DEM with 2.5 m) allowed to build maps of soils and soil properties: carbon content, bulk density, upper boundary of secondary carbonates. Position for chamber-based soil respiration measurements was defined on the basis of these maps. The detailed geodetic and soil surveys of virgin lands and plowland were performed in order to estimate the effect of agrogenic processes such as dehumification, compaction and erosion on soils during the whole period of agricultural use of Central Chernozem reserve area and around. The choice of analogous soils was based on the similarity of their position within the

2006-07-21

Bacterial strains affiliated to the phylogenetically shallowsubcluster C (PnecC) of the 28 Polynucleobacter cluster, which ischaracterized by a minimal 16S rRNA gene sequence similarity of approx.98.5 percent, have been reported to occur as obligate endosymbionts of 30ciliates (Euplotes spp.), as well as to occur as free-living cells in thepelagic zone of freshwater habitats. We investigated if these two groupsof closely related bacteria represent 32 strains fundamentally differingin lifestyle, or if they simply represent different stages of afacultative endosymbiotic lifestyle. The phylogenetic analysis of 16SrRNA gene and 16S34 23S ITS sequences of five endosymbiont strains fromtwo different Euplotes species and 40 pure culture strains demonstratedhost-species-specific clustering of the endosymbiont 36 sequences withinthe PnecC subcluster. The sequences of the endosymbionts showedcharacteristics indicating an obligate endosymbiotic lifestyle.Cultivation experiments 38 revealed fundamental differences inphysiological adaptations, and determination of the genome sizesindicated a slight size reduction in endosymbiotic strains. We concludethat the 40 two groups of PnecC bacteria represent obligately free-livingand obligately endosymbiotic strains, respectively, and do not representdifferent stages of the same complex lifecycle. 42 These closely relatedstrains occupy completely separated ecological niches. To our bestknowledge, this is the closest phylogenetic relationship between obligateendosymbionts and 44 obligately free-living bacteria everrevealed.

Shell trips over its reserves

Jemain, A.

2004-01-01

Some mistakes in the evaluation of the proven reserves of Royal Dutch Shell group, the second world petroleum leader, will oblige the other oil and gas companies to be more transparent and vigilant in the future. The proven reserves ('P90' in petroleum professionals' language) are the most important indicators of the mining patrimony of companies. These strategic data are reported each year in the annual reports of the companies and are examined by the security exchange commission. The evaluation of reserves is perfectly codified by the US energy policy and conservation act and its accountable translation using the FAS 69 standard allows to establish long-term cash-flow forecasts. The revision announced by Shell on January 9 leads to a 20% reduction of its proven reserves. Short paper. (J.S.)

Restoration of Degraded Soil in the Nanmangalam Reserve Forest with Native Tree Species: Effect of Indigenous Plant Growth-Promoting Bacteria.

Science.gov (United States)

Ramachandran, Andimuthu; Radhapriya, Parthasarathy

Restoration of a highly degraded forest, which had lost its natural capacity for regeneration, was attempted in the Nanmangalam Reserve Forest in Eastern Ghats of India. In field experiment, 12 native tree species were planted. The restoration included inoculation with a consortium of 5 native plant growth-promoting bacteria (PGPB), with the addition of small amounts of compost and a chemical fertilizer (NPK). The experimental fields were maintained for 1080 days. The growth and biomass varied depending on the plant species. All native plants responded well to the supplementation with the native PGPB. The plants such as Pongamia pinnata, Tamarindus indica, Gmelina arborea, Wrightia tinctoria, Syzygium cumini, Albizia lebbeck, Terminalia bellirica, and Azadirachta indica performed well in the native soil. This study demonstrated, by using native trees and PGPB, a possibility to restore the degraded forest.

Revising Sangiovanni's reciprocity-based internationalism: towards international egalitarian obligations

Directory of Open Access Journals (Sweden)

Conor Heaney

2016-06-01

Full Text Available To whom do we owe obligations of socio-economic justice? How are such obligations generated? Internationalism denotes a range of approaches to these questions. This paper examines Andrea Sangiovanni's—an internationalist—response to these questions. Sangiovanni argues that we owe egalitarian obligations only to those in the state, and that egalitarian obligations are generated through relationships of ‘reciprocity’. His is a ‘reciprocity-based internationalism’ (RBI. RBI has two components—one normative and another empirical. In this paper, I will assume the normative component, but reject its empirical component. My rejection of the empirical component has normative implications for RBI, which generate egalitarian obligations beyond the state. In other words, my revision of RBI is an argument in favour of international egalitarian obligations not generated through cosmopolitanism, but through internationalism.

Social categories as markers of intrinsic interpersonal obligations.

Science.gov (United States)

Rhodes, Marjorie; Chalik, Lisa

2013-06-01

Social categorization is an early-developing feature of human social cognition, yet the role that social categories play in children's understanding of and predictions about human behavior has been unclear. In the studies reported here, we tested whether a foundational functional role of social categories is to mark people as intrinsically obligated to one another (e.g., obligated to protect rather than harm). In three studies, children (aged 3-9, N = 124) viewed only within-category harm as violating intrinsic obligations; in contrast, they viewed between-category harm as violating extrinsic obligations defined by explicit rules. These data indicate that children view social categories as marking patterns of intrinsic interpersonal obligations, suggesting that a key function of social categories is to support inferences about how people will relate to members of their own and other groups.

Is there a moral obligation not to infect others?

Science.gov (United States)

Harris, J; Holm, S

1995-11-04

The emergence of HIV infection and AIDS has refocused concern on the obligations surrounding the carrying and transmission of communicable diseases. This article asks three related questions: Is there a general duty not to spread contagion? Are there special obligations not to communicate disease in the workplace? And does the mode of transmission of the disease affect the ethics of transmission and, if so, how and to what extent? There seems to be a strong prima facie obligation not to harm others by making them ill where this is avoidable, and this obligation not to communicate disease applies as much to relatively trivial diseases like the common cold as it does to HIV disease. The reasonableness of expecting people to live up to this obligation, however, depends on society reciprocating the obligation in the form of providing protection and compensation.

Full Text Available It is aimed to show our position on the (no need of the civil action filing the record in property, subject of the registration of the demand that is intended to be obliged to institute legal nature reserve area, making use, therefore, of the adoption of hypothetical deductive method, combined with the execution of theoretical and documentary research. Legal Nature Reserve is understood as the area of rural land that can not suffer human intervention by deforestation and exploitation of its resources. Its institution and subsequent registration with the Rural Environmental Registry is an propter rem obligation, given the tracking of it and the attachment to the holder of real right. It must be obeyed even that forests or other type of vegetation no longer exist in the property, which thus externalizes its institution being a mandatory requirement for regular registration of the property, making it impossible to any claim of its ignorance, because it clings to the ownership of the property, passing to new owners, they being able to be charged regardless of their proceeding.

Lessee's obligations under the oil and gas lease

International Nuclear Information System (INIS)

Malcolm, R.T.

1998-01-01

Obligations of a lessee under the present day freehold petroleum and natural gas lease are described. The effect of recent cases relating to fiduciary and good faith duties on the lessee's obligations are also examined. Every lease under the Canadian Association of Petroleum Landmen (CAPL) must specifically deal with rights to be granted, the obligations to drill, royalties, the length of the primary term, the amount of the rental rights, rights to pool, and offset obligations. In Alberta, the most accepted petroleum and natural gas lease form is the CAPL 91. This form is presently being revised to create the 1998 version. The contents of this discussion included: (1) historical lease interpretation, (2) fiduciary obligations, (3) the definition of the doctrine of good faith, (4) implied and express covenants, (5) application of the default clause and (6) force majeur provisions. Although Alberta law does not recognize the doctrine of good faith, nevertheless the court will review the obligations of the lessee and if they do not feel that the lessee has acted fairly with respect to the lessor and damages have resulted, the court will find for the lessor

Whistleblowing and the bioethicist's public obligations.

Science.gov (United States)

MacDougall, D Robert

2014-10-01

Bioethicists are sometimes thought to have heightened obligations by virtue of the fact that their professional role addresses ethics or morals. For this reason it has been argued that bioethicists ought to "whistleblow"--that is, publicly expose the wrongful or potentially harmful activities of their employer--more often than do other kinds of employees. This article argues that bioethicists do indeed have a heightened obligation to whistleblow, but not because bioethicists have heightened moral obligations in general. Rather, the special duties of bioethicists to act as whistleblowers are best understood by examining the nature of the ethical dilemma typically encountered by private employees and showing why bioethicists do not encounter this dilemma in the same way. Whistleblowing is usually understood as a moral dilemma involving conflicting duties to two parties: the public and a private employer. However, this article argues that this way of understanding whistleblowing has the implication that professions whose members identify their employer as the public-such as government employees or public servants--cannot consider whistleblowing a moral dilemma, because obligations are ultimately owed to only one party: the public. The article contends that bioethicists--even when privately employed--are similar to government employees in the sense that they do not have obligations to defer to the judgments of those with private interests. Consequently, bioethicists may be considered to have a special duty to whistleblow, although for different reasons than those usually cited.

Trends in deforestation and forest degradation after a decade of monitoring in the Monarch Butterfly Biosphere Reserve in Mexico.

Vidal, Omar; López-García, José; Rendón-Salinas, Eduardo

2014-02-01

We used aerial photographs, satellite images, and field surveys to monitor forest cover in the core zones of the Monarch Butterfly Biosphere Reserve in Mexico from 2001 to 2012. We used our data to assess the effectiveness of conservation actions that involved local, state, and federal authorities and community members (e.g., local landowners and private and civil organizations) in one of the world's most iconic protected areas. From 2001 through 2012, 1254 ha were deforested (i.e., cleared areas had <10% canopy cover), 925 ha were degraded (i.e., areas for which canopy forest decreased), and 122 ha were affected by climatic conditions. Of the total 2179 ha of affected area, 2057 ha were affected by illegal logging: 1503 ha by large-scale logging and 554 ha by small-scale logging. Mexican authorities effectively enforced efforts to protect the monarch reserve, particularly from 2007 to 2012. Those efforts, together with the decade-long financial support from Mexican and international philanthropists and businesses to create local alternative-income generation and employment, resulted in the decrease of large-scale illegal logging from 731 ha affected in 2005-2007 to none affected in 2012, although small-scale logging is of growing concern. However, dire regional social and economic problems remain, and they must be addressed to ensure the reserve's long-term conservation. The monarch butterfly (Danaus plexippus) overwintering colonies in Mexico-which engage in one of the longest known insect migrations-are threatened by deforestation, and a multistakeholder, regional, sustainable-development strategy is needed to protect the reserve. © 2013 Society for Conservation Biology.

Displacement and gratitude: accounting for the political obligation of refugees

Directory of Open Access Journals (Sweden)

Jason D'Cruz

2014-03-01

Full Text Available On what basis, and to what extent, are refugees obligated to obey the laws of their host countries? Consideration of the specific case of asylum-seekers generates, I think, two competing intuitions: (1 the refugee has a prima facie obligation to obey the laws of her host country and (2 none of the popularly canvassed substrates of political obligation—consent, tacit consent, fairness, or social role—is at all apt to explain the presence of this obligation. I contend that the unfashionable gratitude account of political obligation does the best job of accounting for the intuitions. As has been noticed by other commentators, obligations of gratitude are difficult to specify and subject to numerous cancelling conditions. I analyze these conditions in detail and conclude that if one accepts that gratitude is the basis of the political obligation of the refugee, then one must face up to just how frangible the obligation is. In particular, the obligation is conditional on the fair and generous treatment of refugees that is consistent with their dignity as human beings.

Full Text Available Preservation of terrestrial fauna and flora has been the main reason for the settlement of most protected areas in the past 30 years, but although those areas may include water bodies, this does not necessarily mean that the biodiversity of freshwater environments are also protected. In the present study, the fauna inventory of eight streams (1st, 2nd, 4th and 5th orders of three microbasins of Japi Mountain, a Biosphere Reserve of Atlantic Forest recognised by UNESCO since 1994, located in São Paulo state, southeast of Brazil, was conducted. The hypothesis of this study is that the conservation of this area is important for the maintenance of the aquatic biodiversity of this biome, and so, this world hotspot deserves priority conservation actions. From 2005 to 2007, benthic macroinvertebrates, fishes and, eventually, anuran amphibians were sampled in these streams. The results showed that Japi Mountain contributes to the conservation of 138 taxonomic units of the aquatic biota and covers a rich and representative biodiversity of freshwater fauna of the world (0.2%, Neotropical region (0.9%, Brazil (2.4% and São Paulo state (17.9%. The studied streams in the Environmental Protection Area help protect endangered taxa like the fishes Neoplecostomus paranensis and Pareiorhina cf rudolphi, and shelter freshwater invertebrates and fishes whose distribution is restricted to the Brazilian territory. Japi Mountain is also an important haven of species that was missing there like the frog species Vitreorana eurygnatha. Thus, this species inventory emphasises the importance of conservation actions of the freshwater environments of this Biosphere Reserve of Atlantic Forest.

Inability and Obligation in Moral Judgment

Science.gov (United States)

Buckwalter, Wesley; Turri, John

2015-01-01

It is often thought that judgments about what we ought to do are limited by judgments about what we can do, or that “ought implies can.” We conducted eight experiments to test the link between a range of moral requirements and abilities in ordinary moral evaluations. Moral obligations were repeatedly attributed in tandem with inability, regardless of the type (Experiments 1–3), temporal duration (Experiment 5), or scope (Experiment 6) of inability. This pattern was consistently observed using a variety of moral vocabulary to probe moral judgments and was insensitive to different levels of seriousness for the consequences of inaction (Experiment 4). Judgments about moral obligation were no different for individuals who can or cannot perform physical actions, and these judgments differed from evaluations of a non-moral obligation (Experiment 7). Together these results demonstrate that commonsense morality rejects the “ought implies can” principle for moral requirements, and that judgments about moral obligation are made independently of considerations about ability. By contrast, judgments of blame were highly sensitive to considerations about ability (Experiment 8), which suggests that commonsense morality might accept a “blame implies can” principle.

Review of International Experience with Renewable Energy Obligation Support Mechanisms

Energy Technology Data Exchange (ETDEWEB)

Wiser, R.

2005-06-01

The main policy instruments currently used in the EU Member States to achieve the targets set for electricity produced from renewable energy sources are: (1) the quota obligation system; (2) the feed-in tariff system; and (3) the tendering system. The current study aims to review the experience gained with the quota obligation system. The report provides an overview of the regions where obligation systems have been implemented and contains a detailed evaluation of the performance of the obligation systems in the USA, the UK and in Sweden. The obligation systems in these countries have been evaluated based on the following criteria: Effectiveness; Market efficiency; Certainty for the renewable energy industry; Cost effectiveness; Stakeholder support for the obligation system; and Equity. The evaluation of international experiences with the obligation system gives rise to a mixed picture. Although an obligation in theory is effective and cost effective, it seems too early to conclude that the system delivers these promises in practice. On the one hand this is due to the limited period of implementation that makes it hard to distinguish between the direct effect of the system and some teething problems that will be solved in due time. On the other hand, the conclusion can be drawn that the obligation is a complex system, which will only function well if designed carefully. It does seem worthwhile, however, to continue monitoring the experiences with the obligation system abroad, because this will further reveal whether the system is indeed effective and cost effective in practice. In the longer term, e.g. beyond 2010, the introduction of an obligation system in the Netherlands could be considered. Finally, as the design of support schemes is being improved, it appears that the basic concepts of both the obligation system and the feed in system have been refined in such a way that the two systems are gradually converging. An important difference between the two systems

Pseudomonas aeruginosa and Staphylococcus aureus are thought to cause the majority of lung infections in patients with cystic fibrosis (CF). However, other bacterial pathogens may contribute to the pathophysiology of lung disease. Here, obligate anaerobes were identified in a cross-sectional study, and cell numbers and antibiotic susceptibilities of facultative and obligate anaerobes from 114 sputum samples from nine children and 36 adults with CF were determined. Furthermore, in 12 CF patients, we investigated whether conventional intravenous antibiotic therapy, administered during acute exacerbations, would affect the numbers of obligate anaerobes. Fifteen genera of obligate anaerobes were identified in 91% of the CF patients. Cell numbers (mean: 2.2 x 10(7) +/- standard deviation 6.9 x 10(7) CFU/mL of sputum sample) were comparable to those of P. aeruginosa and S. aureus. Staphylococcus saccharolyticus and Peptostreptococcus prevotii were most prevalent. Infection with P. aeruginosa did not increase the likelihood that obligate anaerobes are present in sputum specimens. Single obligate anaerobic species persisted for up to 11 months in sputum plugs in vivo. Patients with and without obligate anaerobes in sputum specimens did not differ in lung function. Intravenous therapy directed against P. aeruginosa during acute exacerbations increased lung function, but did not reduce the numbers of obligate anaerobes. Obligate anaerobic species differed widely in their patterns of resistance against meropenem, piperacillin-tazobactam, clindamycin, metronidazole and ceftazidime. In 58% of patients with acute exacerbations, obligate anaerobes were detected that were resistant to the antibiotics used for treatment. Antibiotic therapy, optimized to target anaerobes in addition to P. aeruginosa, may improve the management of CF lung disease.

CHANGES IN FOREST COVERAGE IN THE NATURAL RESERVE AGUA SELVA, MEXICO

Directory of Open Access Journals (Sweden)

Camerino Alejandro Montiel

2010-03-01

Full Text Available The impact of ecotourism on the Natural Reserve Agua Selva, Mexico, was assessed. Changes of land use in the forest were evaluated.  An analysis of some socio-economic and cultural changes in the community since ecotourism was introduced was carried out. The perception of villagers towards ecotourism is also presented. The analysis was made with satellite images landsat type (sensor MSS and TM obtained in 1976 and 2000. Cartography and farm plots were also used for the analysis of land use changes. Socio-economic changes were analyzed based on questionnaires and semi-structured interviews. The introduction of ecotourism in the area of study had both positive and negative effects. Although ecotourism did not reverse the deforestation processes, the general deforestation rate was 0.49%. This is smaller to reports in literature for other zones in Tabasco with similar characteristics in the same period of time.  It was found that there was a positive change of Villager’s attitudes towards ecotourism in the last 15 years. This is mainly because this activity is a source of income and has become progressively more important compared to other rural economic activities. It was found that the community participation is scarce and thus has caused problems in the management of specific projects. The results of this research suggest that the success of ecotourism in Agua Selva depends on the integration of ecotourism with the other agricultural and social programs implemented in the area. Implementing agricultural development programs not linked to ecotourism activities can lead to deforestation which is the reserve’s main attraction.

Biofuel plantations on forested lands: double jeopardy for biodiversity and climate.

The growing demand for biofuels is promoting the expansion of a number of agricultural commodities, including oil palm (Elaeis guineensis). Oil-palm plantations cover over 13 million ha, primarily in Southeast Asia, where they have directly or indirectly replaced tropical rainforest. We explored the impact of the spread of oil-palm plantations on greenhouse gas emission and biodiversity. We assessed changes in carbon stocks with changing land use and compared this with the amount of fossil-fuel carbon emission avoided through its replacement by biofuel carbon. We estimated it would take between 75 and 93 years for the carbon emissions saved through use of biofuel to compensate for the carbon lost through forest conversion, depending on how the forest was cleared. If the original habitat was peatland, carbon balance would take more than 600 years. Conversely, planting oil palms on degraded grassland would lead to a net removal of carbon within 10 years. These estimates have associated uncertainty, but their magnitude and relative proportions seem credible. We carried out a meta-analysis of published faunal studies that compared forest with oil palm. We found that plantations supported species-poor communities containing few forest species. Because no published data on flora were available, we present results from our sampling of plants in oil palm and forest plots in Indonesia. Although the species richness of pteridophytes was higher in plantations, they held few forest species. Trees, lianas, epiphytic orchids, and indigenous palms were wholly absent from oil-palm plantations. The majority of individual plants and animals in oil-palm plantations belonged to a small number of generalist species of low conservation concern. As countries strive to meet obligations to reduce carbon emissions under one international agreement (Kyoto Protocol), they may not only fail to meet their obligations under another (Convention on Biological Diversity) but may actually hasten

Handbook on loss reserving

CERN Document Server

Schmidt, Klaus; Schnaus, Anja

2016-01-01

This handbook presents the basic aspects of actuarial loss reserving. Besides the traditional methods, it also includes a description of more recent ones and a discussion of certain problems occurring in actuarial practice, like inflation, scarce data, large claims, slow loss development, the use of market statistics, the need for simulation techniques and the task of calculating best estimates and ranges of future losses. In property and casualty insurance the provisions for payment obligations from losses that have occurred but have not yet been settled usually constitute the largest item on the liabilities side of an insurer's balance sheet. For this reason, the determination and evaluation of these loss reserves is of considerable economic importance for every property and casualty insurer. Actuarial students, academics as well as practicing actuaries will benefit from this overview of the most important actuarial methods of loss reserving by developing an understanding of the underlying stochastic models...

Regular periodical public disclosure obligations of public companies

Directory of Open Access Journals (Sweden)

Marjanski Vladimir

2011-01-01

Full Text Available Public companies in the capacity of capital market participants have the obligation to inform the public on their legal and financial status, their general business operations, as well as on the issuance of securities and other financial instruments. Such obligations may be divided into two groups: The first group consists of regular periodical public disclosures, such as the publication of financial reports (annual, semi-annual and quarterly, and the management's reports on the public company's business operations. The second group comprises the obligation of occasional (ad hoc public disclosure. The thesis analyses the obligation of public companies to inform the public in course of their regular reporting. The new Capital Market Law based on two EU Directives (the Transparency Directive and the Directive on Public Disclosure of Inside Information and the Definition of Market Manipulation regulates such obligation of public companies in substantially more detail than the prior Law on the Market of Securities and Other Financial Instruments (hereinafter: ZTHV. Due to the above the ZTHV's provisions are compared to the new solutions within the domain of regular periodical disclosure of the Capital Market Law.

Anuran road-kills neighboring a peri-urban reserve in the Atlantic Forest, Brazil.

Coelho, Igor Pfeifer; Teixeira, Fernanda Zimmermann; Colombo, Patrick; Coelho, Artur Vicente Pfeifer; Kindel, Andreas

2012-12-15

Mortality from road-kills may figure among the important causes of decline in amphibian populations and species extinctions worldwide. Evaluation of the magnitude, composition, and temporal and spatial distributions of amphibian road-kills is a key step for mitigation planning, especially in peri-urban reserves. Once a month for 16 months, we surveyed, on foot, a 4.4 km section of state road ERS-389 bordering the Itapeva reserve in the southern Atlantic Forest. We recorded 1433 anuran road-kills and estimated a mortality rate of 9002 road-kills/km/year. The species most often recorded were the largest ones: Leptodactylus latrans, Rhinella icterica, Leptodactylus gracilis and Hypsiboas faber; 54.5% of the carcasses could not be identified. Anuran mortality was concentrated in summer, and was associated with temperature, rainfall and photoperiod. Leptodactylus road-kills were strongly influenced by vehicle traffic, probably because of its high abundance during the entire study period. Road-kill hotspots differed for anurans as a group and for single species, and we found an association among spatial patterns of mortality and types of land cover, distance from the nearest waterbody, roadside ditches, and artificial light. Traffic should be banned temporarily during periods of high mortality, which can be forecasted based on meteorological data. A comprehensive mitigation approach should take into account hotspots of all anuran records, and also of target species for selecting locations for amphibian passages and fencing. Roadside ditches, artificial waterbodies, and conventional street lights should be reduced as much as possible, since they may represent ecological traps for anuran populations.

The obligation to contract in British law

Directory of Open Access Journals (Sweden)

Verena Klappstein

2014-06-01

Full Text Available Nowadays the obligation to contract is rarely looked upon. Without reason though, because it is neither outdated nor inoperable. Based on three common law doctrines the obligation to contract goes back to the Middle Ages. It has not lost its relevance, as it can still be found in modern statutory law, such as in the electricity and mail sector. What is more, it is a fundamental institution with a great impact. The analysis showed that the five chosen forms of obligations to contract bear analogical requirements but very similar rationales and economic consequences. It sets impaired market power right and it overstrikes irrational behaviour of market participants. As overall achievement it aligns the range of property, freedom of contract and freedom of competition.

Few Considerations on the Maintenance Obligation in the Romanian Civil Law

Directory of Open Access Journals (Sweden)

Mirela Costache

2017-08-01

Full Text Available Objectives: Recently entered into force, the Romanian Civil Code, systematized on the stable and steady values of the former civil law, reforms the matter of the maintenance obligation, regardless of the source and the legal nature of this obligation. Prior Work: This is the reason why we have chosen this topic and the analysis of the typology to which such an obligation adapts and, of course, the correlative right to which it gives birth. Approach: In our current system of law there are provided different forms of exercising this obligation, preserving, improving, but also innovating, in some aspects, the previous regulation. Specifically, we will relate in this study to a brief analysis of all types of maintenance obligations, generated by two distinct sources: the law and the will of the parties (contract, in this case we are speaking of an obligation based on the law or a contractual obligation. The angle from which we are analyzing this type of obligational relationship between the maintenance creditor and the maintenance debtor also allows us to recall both the passive or active patrimonial side, and also the analysis of the legal characters that it presupposes each of the two above-mentioned generic types of maintenance obligations. Value: Starting from the conceptualization of the maintenance obligation, the present study will be oriented towards the analysis in the current legal context of the doctrinal points of view expressed in the specialized literature, using as a method the documentary research, the interpretative method and the comparative method.

ACCESSORIES OF FISCAL OBLIGATION. LEGAL REGIME

Directory of Open Access Journals (Sweden)

RADA POSTOLACHE

2012-05-01

Full Text Available The interest – which is an institution typical to private law, has been taken over by the fiscal field and adapted to the specific features of fiscal obligation – being defined by its imperative legal regime, which has at the least the following characteristic elements: unitary character, imposed legal percentage, compulsory demand of interest, automatic application. In order to render responsible fiscal debtors, the lawmaker has reintroduced, as an accessory of fiscal obligation, delayed payment penalties, which have a distinct nature and legal regime, but without the principle non bis in idem being transgressed. Our study aims to establish the legal regime ofaccessories typical to fiscal obligation, from the perspective of special normative acts, but also of the common law within the field – Civil Code and Government Ordinance No. 13/2011 – by pointing out at the same time both the particular circumstances and procedural ones regulated by the Fiscal Procedure Code, shedding light upon the controversial legal nature of accessories.

The negative influences of the new brazilian forest code on the conservation of riparian forests

Directory of Open Access Journals (Sweden)

Silva Normandes Matos da

2017-12-01

Full Text Available More than one million hectares of riparian forests were degraded or altered in Mato Grosso State (Brazil up to 2009. The aim of the research is to set a comparative scenario to show differences in the quantification of environmental liabilities in riparian forest areas resulting from the change in native vegetation protection rules due to the transition between Laws 4771/65 and 12651/2012. Data collection took place in a marginal stretch of Vermelho River in Rondonópolis County, Mato Grosso State. The following data set was taken into consideration: aerial images derived from unmanned aerial vehicle, Rapid Eye satellite images and orbital images hosted at Google Earth. The spatial resolution of those images was compared. The aerial photos composed a mosaic that was photo-interpreted to generate land use and occupation classes. The riparian forest areas of a rural property were used as parameter, and their environmental situation was compared in 05 meter and 100 meter strips. Thus, by taking into consideration the current rules, 23,501 m2 of area ceased to be an environmental liability within the riparian forest and became a consolidated rural area. According to the previous Forest Code, in a different scenario, that is, in a set of rural properties, the public authority would receive USD 68,600.00 in fines. The new Brazilian Forestry Code of 2012, which replaces the previous one made in 1965, exempts those responsible for rural property from regenerating previously deforested native vegetation - an obligation established by older Forest Code. We have shown that the new Forest Code has diminished the legal responsibility of the rural owners in relation to the maintenance of forest fragments in their properties.

Novation as a method of termination of obligations

Directory of Open Access Journals (Sweden)

Perović Marko

2017-01-01

Full Text Available The paper presents an analysis of the issue of novation in contract law. Novation is a contract between the creditor and debtor in order to replace its existing obligation with a new one. Unlike the other methods of termination of obligations (e.g. fulfillment, compensation, remission of debt, novation extinguishes existing contractual relationship between the creditor and the debtor, so that among them arise a new contractual relationship, which in relation to the previous one, differs on the case or legal basis. In most of the modern codifications of civil law, novation obtained a particular use in relation to the classical Roman law, which included a change of persons in obligations. In Serbian law, novation also has took the particular use and it takes an important place among many other termination methods of obligations. The analysis made in this paper, focused to the theoretical arguments and practical significance of the novation, brings the author to the conclusions and recommendations relevant to the novation in the theory and practices of contract law.

Using DNA Barcodes to Identify Road-Killed Animals in Two Atlantic Forest Nature Reserves, Brazil.

Directory of Open Access Journals (Sweden)

Angélica H Klippel

Full Text Available Road mortality is the leading source of biodiversity loss in the world, especially due to fragmentation of natural habitats and loss of wildlife. The survey of the main species victims of roadkill is of fundamental importance for the better understanding of the problem, being necessary, for this, the correct species identification. The aim of this study was to verify if DNA barcodes can be applied to identify road-killed samples that often cannot be determined morphologically. For this purpose, 222 vertebrate samples were collected in a stretch of the BR-101 highway that crosses two Discovery Coast Atlantic Forest Natural Reserves, the Sooretama Biological Reserve and the Vale Natural Reserve, in Espírito Santo, Brazil. The mitochondrial COI gene was amplified, sequenced and confronted with the BOLD database. It was possible to identify 62.16% of samples, totaling 62 different species, including Pyrrhura cruentata, Chaetomys subspinosus, Puma yagouaroundi and Leopardus wiedii considered Vulnerable in the National Official List of Species of Endangered Wildlife. The most commonly identified animals were a bat (Molossus molossus, an opossum (Didelphis aurita and a frog (Trachycephalus mesophaeus species. Only one reptile was identified using the technique, probably due to lack of reference sequences in BOLD. These data may contribute to a better understanding of the impact of roads on species biodiversity loss and to introduce the DNA barcode technique to road ecology scenarios.

Obligations of low income countries in ensuring equity in global health financing.

Science.gov (United States)

Barugahare, John; Lie, Reidar K

2015-09-08

Despite common recognition of joint responsibility for global health by all countries particularly to ensure justice in global health, current discussions of countries' obligations for global health largely ignore obligations of developing countries. This is especially the case with regards to obligations relating to health financing. Bearing in mind that it is not possible to achieve justice in global health without achieving equity in health financing at both domestic and global levels, our aim is to show how fulfilling the obligation we propose will make it easy to achieve equity in health financing at both domestic and international levels. Achieving equity in global health financing is a crucial step towards achieving justice in global health. Our general view is that current discussions on global health equity largely ignore obligations of Low Income Country (LIC) governments and we recommend that these obligations should be mainstreamed in current discussions. While we recognise that various obligations need to be fulfilled in order to ultimately achieve justice in global health, for lack of space we prioritise obligations for health financing. Basing on the evidence that in most LICs health is not given priority in annual budget allocations, we propose that LIC governments should bear an obligation to allocate a certain minimum percent of their annual domestic budget resources to health, while they await external resources to supplement domestic ones. We recommend and demonstrate a mechanism for coordinating this obligation so that if the resulting obligations are fulfilled by both LIC and HIC governments it will be easy to achieve equity in global health financing. Although achieving justice in global health will depend on fulfillment of different categories of obligations, ensuring inter- and intra-country equity in health financing is pivotal. This can be achieved by requiring all LIC governments to allocate a certain optimal per cent of their domestic

Zhao, Wei; Shen, Wei Shou; Liu, Hai Yue

2016-12-01

According to the theoretical framework of addressing climate change based on risk mana-gement and the challenge to nature reserve management under climate change, climate change risk of nature reserve was analyzed and defined. Focus on birds and water habitat, grassland habitat, forest habitat, wetland habitat in Dalinuoer Nature Reserve, risk assessment method of nature reserve under climate change was formulated, climate change risks to Dalinuoer Nature Reserve and its habitats were assessed and predicted. The results showed that, during the period from 1997 to 2010, there was significant volatility in dynamic changes of climate change risks to Dalinuoer Nature Reserve and waterbody, grassland, forest, wetland in the region, Dalinuoer Nature Reserve and its habitats were in status of risk in 1999, 2001, 2005 and 2008, wetland habitat was also in status of risk in 2002 and 2004. Under scenario A, B and C, climate change risks to Dalinuoer Nature Reserve and waterbody, grassland, forest, wetland in the region would be more serious in 2020 and 2030, compared with the 2010 level. Climate change risks to different habitats were different significantly, with most serious climate change risk to wetland habitat due to its sensitivity to climate change and rich bird resources. The effect of climate change on nature reserve and related risk would be aggravated by excess utilization of water resource and grassland resource. As climate change risks had appeared in Dalinuoer Nature Reserve, risk management associated with climate change could greatly help to maintain and enhance biodiversity protection function of nature reserves.

Warranty obligations for the management and underground disposal of radioactive waste

International Nuclear Information System (INIS)

Jauho, P.; Silvennoinen, P.

1980-01-01

The need for financial assurances and institutional arrangements for waste management and disposal is discussed from the viewpoint of public interest. The basic principles stated in the paper include the requirement of accumulating funds for future contingencies during the active lifetime of the reactors and the fuel cycle facilities. A governmental role is seen as indispensable in assuming responsibility over at least the surveillance of underground repositories. The stage at which the operational responsibility is transferred from the plant operator to the government is determined in general by the status of the waste conditioning and disposal technology. A brief survey is presented of the current situation and technical issues.The need for special funds is discussed as well. For the part of waste management and disposal that will be taken over by the government an escrow fund should be established. Parallel to this public fund the plant operator would be obliged to reserve funds and provide guarantees within the company to cover liabilities for the remaining part of waste management and disposal obligations. A case study is presented in the paper covering the estimation of the escrow charges for spent fuel or high-level waste. (author)

Value, obligation and the asymmetry question.

Tooley, Michael

1998-04-01

Is there a prima facie obligation to produce additional individuals whose lives would be worth living? In his paper 'Is it good to make happy people?', Stuart Rachels argues not only that there is, but, also, that precisely as much weight should be assigned to the quality of life that would be enjoyed by such potential persons, if they were to be actualized, as to the quality of life enjoyed by actually existing persons. In response, I shall argue, first, that Rachels' view is exposed to very serious objections, and secondly, that his arguments in support of his position involve a crucial assumption, which cannot be sustained, concerning the relation between, on the one hand, propositions about good-making and bad-making properties, and, on the other, propositions about right-making and wrong-making ones. I shall then argue that there is a very plausible position concerning the conditions under which an action can be morally wrong which entails the following asymmetry: there is a prima facie obligation not to bring into existence individuals whose lives are not worth living, but there is no corresponding obligation to create additional individuals whose lives would be worth living.

Full Text Available Abstract Background Worldwide there is growing research interest in the ethnobiology of mangrove forests. Notwithstanding that, little information has been published about ethnobiology of mangrove forests in Cameroon. The aims of this study were a to analyze the harvesting methods and the local selling of mangrove wood products by loggers in the vicinity of Wouri estuary and b to investigate the patterns of subsistence uses of mangrove wood products around the Douala-Edea reserve. Methods Semi-structured interviews were conducted with 120 active mangrove loggers in 23 Douala wood markets and 103 households located in three villages (Mbiako, Yoyo I and Yoyo II close to Douala-Edea reserve. In each of the three densely populated villages, every second household was chosen for sampling while in all markets, mangrove loggers were chosen randomly. In addition, log diameters were measured in each market using a wooden foldable tape measure. A post hoc analysis (Newman-Keuls test was performed in order to detect the common wood class diameter sold in the Douala wood markets. Results The analysis of the loggers' survey data has shown that large logs of Rhizophora with diameter greater than 40 cm were common in the Douala wood markets and were more closely associated with loggers who used chainsaws. In addition to the general mangroves wood products selling, the analysis on a subsistence level (households' survey suggests the local population's dependence on mangroves, with multiple uses of Rhizophora racemosa Meyer, R. harrisonii Leechman, Avicennia germinans L.

2008-02-15

This report evaluates the Ecuadorian proposal to have the international community compensate Ecuador for not exploiting the oil in the ITT area of Yasuni National Park. It includes the evaluation of this proposal in a broader context, assessing the possible consequences of the arrangement for future systems for international payment for biodiversity/rain forest conservation or payment for other ecosystem services as outlined in the Millennium Ecosystem Assessment. Recently, the debate about international funding of rain forest conservation and payment for ecosystem services in general has received new momentum thanks to the climate change negotiations. Although the debate goes back several decades, the content has now been broadened to include at least five major concerns: carbon sequestration and uptake, biodiversity conservation, maintenance and balance of other ecosystem services, safeguarding the livelihoods of local and indigenous people, and adaptation to climate change. This report examines the various past and current efforts relating to the question of international payment for forest conservation, linking it to the international obligations of developed countries to support global environmental goals in developing countries. The Yasuni case raises several questions that are also relevant to the Norwegian Bali initiative to contribute NOK 3 billion annually over five years for forest conservation. A central question is how these (new) flows of funding should be organized in order to achieve the relevant internationally agreed objectives emanating from multilateral environmental agreements. Here we discuss the role of the GEF, with its implementing agencies the World Bank, UNDP and UNEP. We tie the discussion to the obligations that developed countries have undertaken to support the implementation of global environmental goals in developing countries as emanating from the Convention on Biological Diversity (CBD), as well as obligations pertaining to

HUMIDIFICATION AS A FACTOR OF STRUCTURIAL ORGANIZATION OF BIRD POPULATIONS IN THE WOOD STANDS OF THE BIOSPHERE RESERVE ASKANIA NOVA

Directory of Open Access Journals (Sweden)

Listopadsky M. A.

2014-04-01

Full Text Available The influence of different humidification types towards appearance of forest vegetation conditions on spatial organization of birds in the wood stands is analyzed. Population density, coefficient of occurrence, and informative connection with six types of soil humidification are given for 53 bird species. The informative estimation of every humidification type is determined for every bird species. Thereby it is definitely a contribution of every gradation of edaphic factor to the structural genesis of dendrophilous bird communities. The strongest informative connection between humidity gradients and the avifauna structure of the wood stands is available in dry edaphotopes for margin representatives and fresh one for typical forest species. These two humidification types play a start function in the structural genesis of some blocks of dendrophilous bird communities per se. It is determined that change of bird species of forest-steppe faunogenetic complex by species from Nemoral complex undergoes in most cases on the border of the gradient between fresh and humid edaphotopes. For 53 species of birds from dendrophilous complex is was revealed that the importance of different levels of soil moisture has a different impact in shaping of the modern structure dendrophilous avifauna. Dry and especially drily edaphotopes determine the spatial structure of the species that are of forest-steppe origin and belong to the representatives of the optional component of dendrophilous bird communities. Wet edafotopes are involved in the formation of the spatial structure of species of predominantly immoral origin and relate to the obligate component of representatives of dendrophilous bitd comminities. Gradient wetting of edaphotopes on the verge of ‘linked’/’fresh’ is restructuring for the bird communities. It takes an optional replacement red communists feature to obligate.

Brazil faces an enormous challenge to implement its revised Forest Code. Despite big losses for the environment, the law introduces new mechanisms to facilitate compliance and foster payment for ecosystem services (PES). The most promising of these is a market for trading forest certificates (CRAs) that allows landowners to offset their restoration obligations by paying for maintaining native vegetation elsewhere. We analyzed the economic potential for the emerging CRA market in Brazil and its implications for PES programs. Results indicate a potential market for trading 4.2 Mha of CRAs with a gross value of US$ 9.2±2.4 billion, with main regional markets forming in the states of Mato Grosso and São Paulo. This would be the largest market for trading forests in the world. Overall, the potential supply of CRAs in Brazilian states exceeds demand, creating an opportunity for additional PES programs to use the CRA market. This expanded market could provide not only monetary incentives to conserve native vegetation, but also environmental co-benefits by fostering PES programs focused on biodiversity, water conservation, and climate regulation. Effective implementation of the Forest Code will be vital to the success of this market and this hurdle brings uncertainty into the market. Long-term commitment, both within Brazil and abroad, will be essential to overcome the many challenges ahead.

IRINELA – CONSTANTINA BADEA

2015-12-01

Full Text Available The aim of this paper is to analyze the asset structure and the coverage of gross technical reserves of the Insurance – Reinsurance Company Astra SA, for the period 2003 – 2014. Insurance companies are required to constitute technical reserves, in order to cope with the payment obligations to policyholders. These reserves may only be covered on account of certain assets, admitted by law. In Romania, Orders No. 8 and 9/2011, issued by the Insurance Supervisory Commission, contain Rules regarding the assets admitted to cover gross technical reserves, the dispersion of assets admitted to cover gross technical reserves and the liquidity coefficient. Order No. 9/2011, relating to general insurance, has been amended by Rule No. 22/2014. In this paper, we have analyzed the main elements of Astra’s assets, their share in total assets and we have calculated the coverage of gross technical reserves by total assets and liquid assets. In 2013 and 2014, the value of total assets was below the value of gross tehnical reserves, which demonstrated Astra’s financial instability, through negative capital and the inability to meet the obligations to policyholders. Failure to comply with the prudential indicators has been one of the main causes of Astra`s bankruptcy.

Full Text Available Conventional managed forests and sacred groves are seldom assessed to determine their effectiveness in biodiversity conservation strategies. This study investigated tree and insect diversity in Jachie sacred grove (JSG and Nkrabea forest reserve (NFR in Ashanti region, Ghana. The study area constituted eight plots of 50 × 50 m along two 300 m long transects. Insects were sampled in eight pitfall traps, diagonally between the transects. Out of 150 individuals, 13 species in NFR and 15 species from JSG were registered. Celtis mildbraedii was the most dominant species in NFR = 43.18% and JSG = 23.58%. Mean DBH showed a significant relationship with basal area in NFR and JSG. Tree diversity and richness were higher in JSG (H′ = 1.43–2.3 ± 0.10; D = 1.8–3.69 ± 0.30 compared to NFR (H′ = 0.86–1.56 ± 0.09; D = 1.1–2.3 ± 0.57. However, insect diversity was higher in NFR (H′ = 1.34 ± 0.10 than in JSG (H′ = 0.5 ± 0.005. Camponotus furvus and Pachycondyla tarsata were most abundant in JSG and NFR, respectively. These findings will help conservationists work closely with traditional authorities in protecting sacred groves as key biodiversity hotspots.

Collateralized debt obligations (CDOs

2012-01-01

Full Text Available Collateralized debt obligations (CDOs were issued in 1987 by bankers at Drexel Burnham Lambert Inc. A decade later, CDOs became the leading power on the credit derivative markets, on which the value of derivative assets was derived from the value of other assets. However, unlike options and credit swamps, CDOs are not real, which means that they are constructed, and sometimes even the construction of their construction. CDOs were made to satisfy different types of investors, at one end, there is low-risk with low-income, and at the other, high-risk with high-income. By 2007, following the bubble burst on the US real estate market, losses on the CDO market started to expand. By 2008, the crisis on the CDO market turned into what we call today 'the global financial crisis.' CDOs are 'in the heart' of the crisis, and even wider. Our attempt is to reveal the mechanism of collateralized debt obligations (CDOs and the way in which CDOs expanded the negative effects of the present global financial crisis.

Advances in genetic manipulation of obligate intracellular bacterial pathogens

Directory of Open Access Journals (Sweden)

Paul eBeare

2011-05-01

Full Text Available Infections by obligate intracellular bacterial pathogens result in significant morbidity and mortality worldwide. These bacteria include Chlamydia spp., which causes millions of cases of sexually transmitted disease and blinding trachoma annually, and members of the α-proteobacterial genera Anaplasma, Ehrlichia, Orientia and Rickettsia, agents of serious human illnesses including epidemic typhus. Coxiella burnetii, the agent of human Q fever, has also been considered a prototypical obligate intracellular bacterium, but recent host cell-free (axenic growth has rescued it from obligatism. The historic genetic intractability of obligate intracellular bacteria has severely limited molecular dissection of their unique lifestyles and virulence factors involved in pathogenesis. Host cell restricted growth is a significant barrier to genetic transformation that can make simple procedures for free-living bacteria, such as cloning, exceedingly difficult. Low transformation efficiency requiring long term culture in host cells to expand small transformant populations is another obstacle. Despite numerous technical limitations, the last decade has witnessed significant gains in genetic manipulation of obligate intracellular bacteria including allelic exchange. Continued development of genetic tools should soon enable routine mutation and complementation strategies for virulence factor discovery and stimulate renewed interest in these refractory pathogens. In this review, we discuss the technical challenges associated with genetic transformation of obligate intracellular bacteria and highlight advances made with individual genera.

Re-introduction programme has been adopted in solving the conflict issues related with the Malayan sun bears in Peninsular Malaysia. Two rehabilitated sun bears (#1533 and #1532) were collared and released in Tembat Forest Reserve, Hulu Terengganu to study the home-range and activity pattern. Tracking of sun bear in wild have be conducted manually by using telemetry devices namely radio frequency systems and GPS-UHF download system. A total of 912 locations were recorded. The home range size (indicate by the size of convex polygon) of bear #1533 is larger than bear #1532, with value of 95% minimum convex polygon was 130 km2 compared to its counterpart was 33.28 km2. Bears moved to forest (primary and secondary) and oil palm area. Bear #1533 and #1532 were more active in daytime (diurnal) especially from sunrise to midday. Activity pattern of both rehabilitated bears suggested influence by their daily activity in captivity. This study has proposed two guidelines in re-introduction, 1) minimum distance between release site and possible conflict area is 10-13 km and 2) release during the bear's active time.

Full Text Available Based on the floristic composition and structural aspects, the formation tropical dry forest of the reserve "Los Besotes" (Valledupar, Cesar; 248 y 1046m of altitude was characterized. In 35 individuals from nine dominant tree species in two forest types, the phenological characteristics were assessed. Seven monitoring were performed along one year according to the scheme of distribution of rainfall. The leaf fall in the forests of Myrcianthes aff. fragrans and Brosimum alicastrum did not exceed 20% regardless of the climatic period (drought or rainy seasons. In others dominant understory species the leaf fall was less than 40%, thus species of the canopy are classified as evergreen while those of the understory as semideciduous. Blooming peaked during the dry season while fruit production peaked during the two rainy seasons. In the forest ofBursera simaruba and Pterocarpus acapulcensis the leaf fall exceeded 60% in the dry season, while in the rainy season was only 30%. The leaf fall increased to 60% in others dominant understory species. Both canopy as well as understory species are deciduous. Blooming was observed during the dry season (December to March, and July, but it is also likely to occur in October; fruit production was observed at the end of the rainy season. In the tropical dry forest formation evergreen plant communities with low values of leaf fall (40% and deciduous communities with values greater than 60% are recognized.

Gap phase dynamics are the dominant mode of forest turnover in tropical forests. However, gap processes are infrequently studied at the landscape scale. Airborne lidar data offer detailed information on three-dimensional forest structure, providing a means to characterize fine-scale (1 m) processes in tropical forests over large areas. Lidar-based estimates of forest structure (top down) differ from traditional field measurements (bottom up), and necessitate clear-cut definitions unencumbered by the wisdom of a field observer. We offer a new definition of a forest gap that is driven by forest dynamics and consistent with precise ranging measurements from airborne lidar data and tall, multi-layered tropical forest structure. We used 1000 ha of multi-temporal lidar data (2008, 2012) at two sites, the Tapajos National Forest and Ducke Reserve, to study gap dynamics in the Brazilian Amazon. Here, we identified dynamic gaps as contiguous areas of significant growth, that correspond to areas > 10 m2, with height gap at Tapajos National Forest (4.8 %) as compared to Ducke Reserve (2.0 %). On average, gaps were smaller at Ducke Reserve and closed slightly more rapidly, with estimated height gains of 1.2 m y-1 versus 1.1 m y-1 at Tapajos. At the Tapajos site, height growth in gap centers was greater than the average height gain in gaps (1.3 m y-1 versus 1.1 m y-1). Rates of height growth between lidar acquisitions reflect the interplay between gap edge mortality, horizontal ingrowth and gap size at the two sites. We estimated that approximately 10 % of gap area closed via horizontal ingrowth at Ducke Reserve as opposed to 6 % at Tapajos National Forest. Height loss (interpreted as repeat damage and/or mortality) and horizontal ingrowth accounted for similar proportions of gap area at Ducke Reserve (13 % and 10 %, respectively). At Tapajos, height loss had a much stronger signal (23 % versus 6 %) within gaps. Both sites demonstrate limited gap contagiousness defined by an

Genetic diversity in populations of Maytenus dasyclada (Celastraceae in forest reserves and unprotected Araucaria forest remnants

Directory of Open Access Journals (Sweden)

Manuel Castilhos Reichmann

Full Text Available ABSTRACT Understanding the genetic structure and diversity of plants is fundamental to their conservation and permits their sustainable use by local communities. The genus Maytenus (Celastraceae is composed of plants possessing pharmacological and antioxidant properties. However, the genetic and economic properties of the species M. dasyclada, a typical species of Araucaria forests in Brazil and Uruguay, have been little studied. In this work, the genetic structure and diversity of natural populations of M. dasyclada located in unprotected and preserved forest remnants were investigated using RAPD and isozymes markers. The results demonstrated that in areas of preservation, populations of M. dasyclada possess a relatively high degree of polymorphism and high values for Na, Ne, Shannon index, He and Ho, indicating high genetic variability. Moreover, these protected populations are very close to each other and potentially experience significant gene flow. The results presented here highlight the relevance of preservation areas for the conservation of M. dasyclada, and that populations inhabiting these areas could serve as a genetic source for the recovery of populations in regions where genetic diversity has been lost.

Rugani, Tihomir; Diaci, Jurij; Hladnik, David

2013-01-01

Context Due to a long history of intensive forest exploitation, few European beech (Fagus sylvatica L.) old-growth forests have been preserved in Europe. Material and Methods We studied two beech forest reserves in southern Slovenia. We examined the structural characteristics of the two forest reserves based on data from sample plots and complete inventory obtained from four previous forest management plans. To gain a better understanding of disturbance dynamics, we used aerial imagery to study the characteristics of canopy gaps over an 11-year period in the Kopa forest reserve and a 20-year period in the Gorjanci forest reserve. Results The results suggest that these forests are structurally heterogeneous over small spatial scales. Gap size analysis showed that gaps smaller than 500 m2 are the dominant driving force of stand development. The percentage of forest area in canopy gaps ranged from 3.2 to 4.5% in the Kopa forest reserve and from 9.1 to 10.6% in the Gorjanci forest reserve. These forests exhibit relatively high annual rates of coverage by newly established (0.15 and 0.25%) and closed (0.08 and 0.16%) canopy gaps. New gap formation is dependant on senescent trees located throughout the reserve. Conclusion We conclude that these stands are not even-sized, but rather unevenly structured. This is due to the fact that the disturbance regime is characterized by low intensity, small-scale disturbances. PMID:23308115

Much is known about adult children caring for their aging parents, yet the potentially unique experience of offspring caring for traumatized parents is underexplored. Therefore, the current studies assessed filial anxiety and sense of obligation among offspring of Holocaust survivors (OHS) in caring for their parents. In Study 1, we interviewed 10 OHS (mean age = 61.0) in order to extract themes of filial anxiety. Based on Study 1's data, a newly constructed scale of filial anxiety was administered in Study 2 to 59 adult offspring (mean age = 56.4): 28 OHS and 31 comparisons. Study 3 included 143 dyads of parents and offspring (mean age = 55.4 and 81.7, respectively): 86 Holocaust dyads and 57 comparison dyads. Parents reported posttraumatic stress disorder (PTSD) symptoms and offspring reported filial anxiety and sense of obligation. In Study 1, interviewees referred to concerns about parent experiencing decline alongside caregiving difficulties. In Study 2, OHS reported higher filial anxiety and sense of obligation relative to comparisons. This group difference was mediated by sense of obligation. In Study 3, OHS with parental PTSD reported higher filial anxiety and sense of obligation relative to comparisons. Once more, filial sense of obligation served as a mediator. In Studies 2-3, results remained significant after adjusting for offspring symptoms. Parental exposure to the Holocaust, and especially parental PTSD, related to higher filial obligation, which in turn was related to higher filial anxiety. These findings bear important implications for practitioners working with survivors' families.

Full Text Available The objective of this work was to compare the species richness, abundance and diversity of Scarabaeidae beetles in two types of habitats (field and forest, and to assess whether their seasonal variation is related to climatic variables. This study was conducted in the São Donato Biological Reserve, Rio Grande do Sul state, Brazil (Pampa biome. Beetles were collected using pitfall traps between January 2012 and January 2013. A total of 125 individuals were collected, of which six genera and 11 species from four subfamilies of Scarabaeidae were identified. 54 individuals of five species were collected from the field, and 71 individuals of eight species were collected from the forest. The most abundant species were Ataenius picinus Harold, 1868, Canthon lividus Blanchard, 1845 and Leucothyreus lavipes Eschscholtz, 1822, which together accounted for 86.4% of all individuals captured. The highest total number of individuals was collected in summer (78, and the highest number of species was collected in spring (9. Differences in environmental structure (and associated climate and food resource availability may be decisive and limiting factors for beetle occurrence in forest versus field areas, as various species were restricted to a specific habitat type or season.

2017-01-01

The paper presents an analysis of the issue of novation in contract law. Novation is a contract between the creditor and debtor in order to replace its existing obligation with a new one. Unlike the other methods of termination of obligations (e.g. fulfillment, compensation, remission of debt), novation extinguishes existing contractual relationship between the creditor and the debtor, so that among them arise a new contractual relationship, which in relation to the previous one, differs on t...

Physicians' strikes and the competing bases of physicians' moral obligations.

Science.gov (United States)

MacDougall, D Robert

2013-09-01

Many authors have addressed the morality of physicians' strikes on the assumption that medical practice is morally different from other kinds of occupations. This article analyzes three prominent theoretical accounts that attempt to ground such special moral obligations for physicians--practice-based accounts, utilitarian accounts, and social contract accounts--and assesses their applicability to the problem of the morality of strikes. After critiquing these views, it offers a fourth view grounding special moral obligations in voluntary commitments, and explains why this is a preferable basis for understanding physicians' moral obligations in general and especially as pertaining to strikes.

Observer perceptions of moral obligations in groups with a history of victimization.

Science.gov (United States)

Warner, Ruth H; Branscombe, Nyla R

2012-07-01

The authors investigated when observers assign contemporary group members moral obligations based on their group's victimization history. In Experiment 1, Americans perceived Israelis as obligated to help Sudanese genocide victims and as guiltworthy for not helping if reminded of the Holocaust and its descendants were linked to this history. In Experiment 2, participants perceived Israelis as more obligated to help and guiltworthy for not helping when the Holocaust was presented as a unique victimization event compared with when genocide was presented as pervasive. Experiments 3 and 4 replicated the effects of Experiment 1 with Cambodians as the victimized group. Experiment 5 demonstrated that participants perceived Cambodians as having more obligations under high just world threat compared with low just world threat. Perceiving victimized groups as incurring obligations is one just world restoration method of providing meaning to collective injustice.

Forest fragmentation is considered a greater threat to vertebrates than to tree communities because individual trees are typically long-lived and require only small areas for survival. Here we show that forest fragmentation provokes surprisingly rapid and profound alterations in Amazonian tree-community composition. Results were derived from a 22-year study of exceptionally diverse tree communities in 40 1-ha plots in fragmented and intact forests, which were sampled repeatedly before and after fragment isolation. Within these plots, trajectories of change in abundance were assessed for 267 genera and 1,162 tree species. Abrupt shifts in floristic composition were driven by sharply accelerated tree mortality and recruitment within ≈100 m of fragment margins, causing rapid species turnover and population declines or local extinctions of many large-seeded, slow-growing, and old-growth taxa; a striking increase in a smaller set of disturbance-adapted and abiotically dispersed species; and significant shifts in tree size distributions. Even among old-growth trees, species composition in fragments is being restructured substantially, with subcanopy species that rely on animal seed-dispersers and have obligate outbreeding being the most strongly disadvantaged. These diverse changes in tree communities are likely to have wide-ranging impacts on forest architecture, canopy-gap dynamics, plant–animal interactions, and forest carbon storage. PMID:17148598

The moral obligation to be vaccinated: utilitarianism, contractualism, and collective easy rescue.

Science.gov (United States)

Giubilini, Alberto; Douglas, Thomas; Savulescu, Julian

2018-02-10

We argue that individuals who have access to vaccines and for whom vaccination is not medically contraindicated have a moral obligation to contribute to the realisation of herd immunity by being vaccinated. Contrary to what some have claimed, we argue that this individual moral obligation exists in spite of the fact that each individual vaccination does not significantly affect vaccination coverage rates and therefore does not significantly contribute to herd immunity. Establishing the existence of a moral obligation to be vaccinated (both for adults and for children) despite the negligible contribution each vaccination can make to the realisation of herd immunity is important because such moral obligation would strengthen the justification for coercive vaccination policies. We show that two types of arguments-namely a utilitarian argument based on Parfit's Principle of Group Beneficence and a contractualist argument-can ground an individual moral obligation to be vaccinated, in spite of the imperceptible contribution that any single vaccination makes to vaccine coverage rates. We add a further argument for a moral obligation to be vaccinated that does not require embracing problematic comprehensive moral theories such as utilitarianism or contractualism. The argument is based on a "duty of easy rescue" applied to collectives, which grounds a collective moral obligation to realise herd immunity, and on a principle of fairness in the distribution of the burdens that must be borne to realise herd immunity.

Should Social Value Obligations be Local or Global?

Science.gov (United States)

Nayak, Rahul; Shah, Seema K

2017-02-01

According to prominent bioethics scholars and international guidelines, researchers and sponsors have obligations to ensure that the products of their research are reasonably available to research participants and their communities. In other words, the claim is that research is unethical unless it has local social value. In this article, we argue that the existing conception of reasonable availability should be replaced with a social value obligation that extends to the global poor (and not just research participants and host communities). To the extent the social value requirement has been understood as geographically constrained to the communities that host research and the countries that can afford the products of research, it has neglected to include the global poor as members of the relevant society. We argue that a new conception of social value obligations is needed for two reasons. First, duties of global beneficence give reason for researchers, sponsors, and institutions to take steps to make their products more widely accessible. Second, public commitments made by many institutions acknowledge and engender responsibilities to make the products of research more accessible to the global poor. Future research is needed to help researchers and sponsors discharge these obligations in ways that unlock their full potential. Published 2017.

Brazil faces an enormous challenge to implement its revised Forest Code. Despite big losses for the environment, the law introduces new mechanisms to facilitate compliance and foster payment for ecosystem services (PES). The most promising of these is a market for trading forest certificates (CRAs) that allows landowners to offset their restoration obligations by paying for maintaining native vegetation elsewhere. We analyzed the economic potential for the emerging CRA market in Brazil and its implications for PES programs. Results indicate a potential market for trading 4.2 Mha of CRAs with a gross value of US$ 9.2±2.4 billion, with main regional markets forming in the states of Mato Grosso and São Paulo. This would be the largest market for trading forests in the world. Overall, the potential supply of CRAs in Brazilian states exceeds demand, creating an opportunity for additional PES programs to use the CRA market. This expanded market could provide not only monetary incentives to conserve native vegetation, but also environmental co-benefits by fostering PES programs focused on biodiversity, water conservation, and climate regulation. Effective implementation of the Forest Code will be vital to the success of this market and this hurdle brings uncertainty into the market. Long-term commitment, both within Brazil and abroad, will be essential to overcome the many challenges ahead. PMID:27050309

Remote Sensing for Mapping RAMSAR Heritage Site at Sungai Pulai Mangrove Forest Reserve, Johor, Malaysia

International Nuclear Information System (INIS)

Hasmadi, I.M.; Pakhriazad, H.Z.; Norlida, K.

2011-01-01

The Sungai Pulai Mangrove Forest Reserve (SPMFR) is the largest reverin mangrove system in Johore. In 2003 about 9,126 ha of the Sungai Pulai mangrove was designated as a RAMSAR site. RAMSAR sites are wetland areas that are deemed to have international importance and are included in the List of Wetlands of International Importance. The SPMFR plays a significant socio-economic role to the adjacent 38 villages. Satellite remote sensing is a useful source of information where it provides timely and complete coverage for vegetation mapping especially in mangroves where the accessibility is difficult. This study was carried out to identify and map land cover types using SPOT-4 imagery at the Sungai Pulai-RAMSAR site and its surrounding areas. Through unsupervised classification technique a total of seven classes of land cover type were mapped, where about 90 % mapping accuracy was gained from the accuracy assessment. Later, vegetation densities were classified into five levels namely very high, high, medium, low and very low based on crown density scale using vegetation indices model such as NDVI, AVI and OSAVI. Results from NDVI and OSAVI model were almost similar but AVI model detected more on medium vegetation which did not show the real ground condition. The study concludes that SPOT-4 imagery was able to discriminate mangrove area clearly from other land covers type. Vegetation indices model can be used as a tool for mapping vegetation density level in the SPMFR and its surrounding area. Therefore VIs models from remote sensing are useful to monitor and manage the mangrove forest for sustainable management and preserve the SPMFR as a RAMSAR site in Peninsular Malaysia. (author)

Informed consent: Enforcing pharmaceutical companies' obligations abroad.

Science.gov (United States)

Lee, Stacey B

2010-06-15

The past several years have seen an evolution in the obligations of pharmaceutical companies conducting clinical trials abroad. Key players, such as international human rights organizations, multinational pharmaceutical companies, the United States government and courts, and the media, have played a significant role in defining these obligations. This article examines how such obligations have developed through the lens of past, present, and future recommendations for informed consent protections. In doing so, this article suggests that, no matter how robust obligations appear, they will continue to fall short of providing meaningful protection until they are accompanied by a substantive enforcement mechanism that holds multinational pharmaceutical companies accountable for their conduct. Issues of national sovereignty, particularly in the United States, will continue to prevent meaningful enforcement by an international tribunal or through one universally adopted code of ethics. This article argues that, rather than continuing to pursue an untenable international approach, the Alien Torts Statute (ATS) offers a viable enforcement mechanism, at least for US-based pharmaceutical companies. Recent federal appellate court precedent interpreting the ATS provides the mechanism for granting victims redress and enforcing accountability of sponsors (usually pharmaceutical companies and research and academic institutions) for informed consent misconduct. Substantive human rights protections are vital in order to ensure that every person can realize the "right to health." This article concludes that by building on the federal appellate court's ATS analysis, which grants foreign trial participants the right to pursue claims of human rights violations in US courts, a mechanism can be created for enforcing not only substantive informed consent, but also human rights protections.

Do canopy disturbances drive forest plantations into more natural conditions? — A case study from Can Gio Biosphere Reserve, Viet Nam

Large areas of mangrove forests were devastated in South Viet Nam during the second Indochina war. After its end in 1975, extensive reforestation with monocultures took place. Can Gio, one of the biggest replanted sites with about 20,000 ha of mangroves mainly Rhizophora apiculata, was declared a biosphere reserve by the UNESCO in 2000. Although this status now enables progressive forest dynamics, there are still drawbacks resulting from the unnatural character of the plantations. For example, the homogeneous size and age structure as well as the regular arrangement of the planted trees make larger forest stands more vulnerable to synchronized collapsing which can be triggered by stronger winds and storms. A transformation into a more natural forest characterized by a heterogeneous age and size structure and a mixed species composition is of urgent need to avoid a synchronized dieback. In this study we test the capability of natural canopy disturbances (e.g. lightning strikes) to facilitate this transformation.Canopy gaps created by lightning strikes were detected and quantified by remote sensing techniques. SPOT satellite images from the years 2003, 2005 and 2007 provided information about the spatial distribution, size, shape, and formation frequency of the gaps. Lightning strike gaps were identified based on their shape and size. They form small openings (mean: 0.025 ha) and their yearly probability of occurrence was determined to be approximately 0.012 per hectare. Selected gaps were surveyed in the field in 2008 to complement the remote sensing data and to provide information upon forest structure and regeneration.Simulation experiments were carried out with the individual-based KiWi mangrove model for quantifying the influence of different lightning regimes on the vertical and horizontal structure of the R. apiculata plantation. In addition, we conducted simulations with a natural and thus randomly generated forest to compare the structure of the two

Family obligation values as a protective and vulnerability factor among low-income adolescent girls.

Milan, Stephanie; Wortel, Sanne

2015-06-01

Adolescents' beliefs about family obligation often reflect cultural variations in their family context, and thus are important for understanding development among diverse youth. In this study, we test hypotheses about the role of family obligation values in risk behavior and mental health in a sample of 194 low-income adolescent girls (mean age = 15.2; 58% Latina, 28% African-American/Black). We hypothesized that family obligation values can be both a protective and vulnerability factor, depending on the type of outcome and the presence of other risk factors. Across the sample, higher family obligation values tended to occur with indicators of positive family functioning (e.g., more frequent communication, less maternal hostility) based on mother and adolescent reports. As hypothesized, family obligation values moderated the relationship between established risk factors and adjustment in distinct ways, such that high family obligation values decreased risk in some domains (i.e., a protective factor) but increased risk in other domains (i.e., a vulnerability factor). Specifically, high family obligation values diminished the relationship between peer norms for risky behavior (sex and substance use) and individual engagement in those behaviors. At the same time, high family obligation values magnified the relationship between exposure to negative life events and poor mental health (PTSD and depressive symptoms). The results suggest that family obligation is an important but complex aspect of development among diverse adolescent girls.

In Solomon Islands, forests have provided people with ecological services while being affected by human use and protection. This study used a quantitative ethnobotanical analysis to explore the society-forest interaction and its transformation in Roviana, Solomon Islands. We compared local plant and land uses between a rural village and urbanized village. Special attention was paid to how local people depend on biodiversity and how traditional human modifications of forest contribute to biodiversity conservation. After defining locally recognized land-use classes, vegetation surveys were conducted in seven forest classes. For detailed observations of daily plant uses, 15 and 17 households were randomly selected in the rural and urban villages, respectively. We quantitatively documented the plant species that were used as food, medicine, building materials, and tools. The vegetation survey revealed that each local forest class represented a different vegetative community with relatively low similarity between communities. Although commercial logging operations and agriculture were both prohibited in the customary nature reserve, local people were allowed to cut down trees for their personal use and to take several types of non-timber forest products. Useful trees were found at high frequencies in the barrier island's primary forest (68.4%) and the main island's reserve (68.3%). Various useful tree species were found only in the reserve forest and seldom available in the urban village. In the rural village, customary governance and control over the use of forest resources by the local people still functioned. Human modifications of the forest created unique vegetation communities, thus increasing biodiversity overall. Each type of forest had different species that varied in their levels of importance to the local subsistence lifestyle, and the villagers' behaviors, such as respect for forest reserves and the semidomestication of some species, contributed to

This paper presents the detection of Angsi and Berembun Reserve Forest change for years 1996 and 2013. Forest is an important part of our ecosystem. The main function is to absorb carbon oxide and produce oxygen in their cycle of photosynthesis to maintain a balance and healthy atmosphere. However, forest changes as time changes. Some changes are necessary as to give way for economic growth. Nevertheless, it is important to monitor forest change so that deforestation and development can be planned and the balance of ecosystem is still preserved. It is important because there are number of unfavorable effects of deforestation that include environmental and economic such as erosion of soil, loss of biodiversity and climate change. The forest change detection can be studied with reference of several satellite images using remote sensing application. Forest change detection is best done with remote sensing due to large and remote study area. The objective of this project is to detect forest change over time and to compare forest health indicated by Normalized Difference Vegetation Index (NDVI) using remote sensing and image processing. The forest under study shows depletion of forest area by 12% and 100% increment of deforestation activities. The NDVI value which is associated with the forest health also shows 13% of reduction

"Individual responsibility" and the abidance by any "health-related obligations" are key words of the present political and legal German healthcare debate. In the process of adjusting the German welfare state by focussing the ideal allocation of common health resources patients who do not meet their "health-related obligations" are thus expected to accept cutbacks in medical care services. However, from the perspective of constitutional law there is no "health-related obligation" deriving from the German constitution - the right to self-determination guaranteed in Art. 2 Sect. 2 Sent. 1 of the German constitution has not been amended to impose a corresponding duty. Hence, health-related obligations may only refer to indirect ways of exercising individual responsibility, no more and no less. The present article highlights the few possibilities which the German constitution provides for the implementation of "health-related obligations" and reminds us of the conceptual aspects which have to be considered by the legislator.

Forest ownership is considered as a vital aspect for sustainable management of forest and its associated biodiversity. The Global Forest Resources Assessment 2015 reported that privately owned forest area are increasing on a global scale, but deforestation was found very active in privately owned hill forest areas of Malaysia. Penang State was purposively chosen as it has been experiencing rapid and radical changes due to urban expansion over the last three decades. In this study, analyses of land-use changes were done by PCI Geomatica using Landsat images from 1991 to 2015, future trends of land-use change were assessed using EXCEL forecast function, and its impact on the surrounding environment were conducted by reviewing already published articles on changing environment of the study area. This study revealed an annual deforestation rate of 1.4% in Penang Island since 1991. Trend analysis forecasted a forest area smaller than the current forest reserves by the year 2039. Impact analysis revealed a rapid biodiversity loss with increasing landslides, mudflows, water pollution, flash flood, and health hazard. An immediate ban over hill-land development is crucial for overall environmental safety. Copyright © 2017 Elsevier Ltd. All rights reserved.

Manipulation of Host Cholesterol by Obligate Intracellular Bacteria

Directory of Open Access Journals (Sweden)

Dhritiman Samanta

2017-05-01

Full Text Available Cholesterol is a multifunctional lipid that plays important metabolic and structural roles in the eukaryotic cell. Despite having diverse lifestyles, the obligate intracellular bacterial pathogens Chlamydia, Coxiella, Anaplasma, Ehrlichia, and Rickettsia all target cholesterol during host cell colonization as a potential source of membrane, as well as a means to manipulate host cell signaling and trafficking. To promote host cell entry, these pathogens utilize cholesterol-rich microdomains known as lipid rafts, which serve as organizational and functional platforms for host signaling pathways involved in phagocytosis. Once a pathogen gains entrance to the intracellular space, it can manipulate host cholesterol trafficking pathways to access nutrient-rich vesicles or acquire membrane components for the bacteria or bacteria-containing vacuole. To acquire cholesterol, these pathogens specifically target host cholesterol metabolism, uptake, efflux, and storage. In this review, we examine the strategies obligate intracellular bacterial pathogens employ to manipulate cholesterol during host cell colonization. Understanding how obligate intracellular pathogens target and use host cholesterol provides critical insight into the host-pathogen relationship.

Setting: South Africa is the largest producer of platinum in the world. The study covers all platinum mines listed on the JSE. Methods: Using a framework, a census of the annual financial statements, integrated annual reports and sustainability reports or websites was conducted to determine the level of compliance of disclosure relating to mine closure obligations to the recommended disclosure framework. Results: The results show disclosure relating to mine closure obligations of platinum mines listed on the JSE is inconsistent and not sufficient for stakeholders to understand the scope, key assumptions, parameters or reliability of the assessment and calculation of mine closure obligations. Conclusion: The assumptions used to determine mine closure obligations are specialised and multi-disciplinary. The accuracy and reliability of mine closure obligations will improve dramatically through greater transparency and access to information. It is recommended that the JSE listings for mining companies should require a competent person’s report to provide disclosure on assumptions, key values and processes applied to determine the mine closure obligations. Furthermore, it is recommended that the Department of Mineral Resources implements a mechanism of independent assessment of mine closure obligations by experts on an ongoing basis.

Full Text Available In Cuba, Biosphere Reserves protect and keep natural areas of variable size including one or several forest, scrub or grassland vegetation units, either primary or secondary, also taking into account the various kinds of complex vegetation and communities. The Biosphere Reserve Buenavista, located in Central Cuba, includes several primary vegetation units such as the mangrove forest, sandy coast and rocky coast vegetation, littoral scrub and the dry semi-deciduous, semi-deciduous and gallery forests. Ferns and their allies, gimnosperms and angiosperms were determined and listed in the Reserve and dominant or dominated tree taxa were selected, also listing their standard heights with the ultimate purpose of using them in future reforestation planning if deforestation in some zones occurs.

Full Text Available Anthropogenic-origin forest disturbance has been known to increase the risk of invasion to native habitat. Invasive species caused problems for local ecosystems and their native species. The  research on the dynamics and autecology of invasive species Cyperus rotundus was conducted on anthropogenic disturbed Pohen mountain forest in Bali, Indonesia. Results showed significant changes in microclimatic variables from forest edge to interior. C. rotundus in Pohen mountain forest can be found in a road edge and forest exterior where sunlight is abundant and decrease in a more shady sites and absent under thick forest canopies CCA ordination analysis showed that C. rotundus in Pohen mountain forest tends to co-occur together with Imperata cylindrica and Bidens biternata. To be able to control potentially troublesome exotic invasive species, firstly we have to understand what factors limit their growth and development. Therefore this study is has important value because the data which from  result in studying invasive species autecology will act as baseline data that will be useful to generate management program including rehabilitation and restoration program.

Forests in the mountains are a treasure trove; harbour a large biodiversity; and provide fodder, firewood, timber and non-timber forest products; all of these are essential for human survival in the highest mountains on earth. The present paper attempts a spatiotemporal assessment of forest fragmentation and changes in land use land cover (LULC) pattern using multitemporal satellite data over a time span of around a decade (2000-2009), within the third highest protected area (PA) in the world. The fragmentation analysis using Landscape Fragmentation Tool (LFT) depicts a decrease in large core, edge and patches areas by 5.93, 3.64 and 0.66 %, respectively, while an increase in non-forest and perforated areas by 6.59 and 4.01 %, respectively. The land cover dynamics shows a decrease in open forest, alpine scrub, alpine meadows, snow and hill shadow areas by 2.81, 0.39, 8.18, 3.46 and 0.60 %, respectively, and there is an increase in dense forest and glacier area by 4.79 and 10.65 %, respectively. The change analysis shows a major transformation in areas from open forest to dense forest and from alpine meadows to alpine scrub. In order to quantify changes induced by forest fragmentation and to characterize composition and configuration of LULC mosaics, fragmentation indices were computed using Fragstats at class level, showing the signs of accelerated fragmentation. The outcome of the analysis revealed the effectiveness of geospatial tools coupled with landscape ecology in characterization and quantification of forest fragmentation and land cover changes. The present study provides a baseline database for sustainable conservation planning that will benefit the subsistence livelihoods in the region. Recommendations made based on the present analysis will help to recover forest and halt the pessimistic effects of fragmentation and land cover changes on biodiversity and ecosystem services in the region.

The genotypic affinity of 19 bacterial strains obligately dependent on methanol or methylamine as carbon and energy sources was studied by techniques of molecular DNA hybridization. The high homology level (35-88%) between motile strain Methylophilus methanolovorus V-1447D and nonmotile strain Methylobacillus sp. VSB-792 as well as other motile strains (Pseudomonas methanolica ATCC 21704, Methylomonas methanolica NRRL 5458, Pseudomonas sp. W6, strain A3) indicates that all of them belong to one genus. Rather high level of homology (62-63%) was found between Methylobacillus glycogenes ATCC 29475 and Pseudomonas insueta ATCC 21276 and strain G-10. The motile strain Methylophilus methylotrophus NCIB 10515 has a low homology (below 20%) to other of the studied obligate methylobacteria. Therefore, at least two genetically different genera of obligate methylobacteria can be distinguished, namely Methylophilus and Methylobacillus, the latter being represented by both motile and nonmotile forms.

Carbon dioxide is the most abundant greenhouse gas (GHG) that causes global warming. Thus, land uses such as an agroforestry system have a significant role in moderating climate change since they can be sources and sinks of carbon. The aim of the study was to generate data on the carbon stocks of two agroforestry systems, specifically a Gmelina arborea-Theobroma cacao multistorey system and an alley cropping system with Gliricidia sepium hedges at the agroforestry research and demonstration area inside a forest reserve in Southern Luzon, Philippines. The multistorey system had a mean biomass of 258 Mg C ha{sup -1} and a carbon density of 185 Mg C ha{sup -1}. Carbon was stored in the various pools in the following order of magnitude: soil > tree biomass (above-ground) > necromass > understorey vegetation > roots. The Gliricidia hedgerow had a biomass density of 3.8 Mg C ha{sup -1}; total carbon density was 93 Mg C ha{sup -1}, of which 92 Mg C ha{sup -1} was in the soil.

Post-trial obligations in the Declaration of Helsinki 2013: classification, reconstruction and interpretation.

Science.gov (United States)

Mastroleo, Ignacio

2016-08-01

The general aim of this article is to give a critical interpretation of post-trial obligations towards individual research participants in the Declaration of Helsinki 2013. Transitioning research participants to the appropriate health care when a research study ends is a global problem. The publication of a new version of the Declaration of Helsinki is a great opportunity to discuss it. In my view, the Declaration of Helsinki 2013 identifies at least two clearly different types of post-trial obligations, specifically, access to care after research and access to information after research. The agents entitled to receive post-trial access are the individual participants in research studies. The Declaration identifies the sponsors, researchers and host country governments as the main agents responsible for complying with the post-trial obligations mentioned above. To justify this interpretation of post-trial obligations, I first introduce a classification of post-trial obligations and illustrate its application with examples from post-trial ethics literature. I then make a brief reconstruction of the formulations of post-trial obligations of the Declaration of Helsinki from 2000 to 2008 to correlate the changes with some of the most salient ethical arguments. Finally I advance a critical interpretation of the latest formulation of post-trial obligations. I defend the view that paragraph 34 of 'Post-trial provisions' is an improved formulation by comparison with earlier versions, especially for identifying responsible agents and abandoning ambiguous 'fair benefit' language. However, I criticize the disappearance of 'access to other appropriate care' present in the Declaration since 2004 and the narrow scope given to obligations of access to information after research. © 2015 John Wiley & Sons Ltd.

Grazing livestock in openly accessible areas is a common practice in the multiple-use forests of India; however, its compatibility with the reintroduction of tigers to these areas requires examination. Here, we investigated the diet of tigers in a livestock-dominated multiple-use buffer zone of the Panna Tiger Reserve, India. We hypothesised that the presence of feral cattle, along with open-access grazing practices in multiple-use forests, would increase the incidence of predation on livestock by tigers, even when wild prey are available. We used generalised linear models to test whether predation of livestock versus wild animals was influenced by (1) the sex and age class of tigers, (2) season, and (3) the distance of prey from the core-zone boundary of the reserve. Overall, sub-adult tigers and male tigers killed more livestock than wild prey, even when wild prey was available. In the winter and rainy seasons livestock were killed in higher numbers in the buffer zone than in summers, this may be because of the seasonally changing livestock herding patterns in the area. Further, with increasing distance from the core-zone boundary, all tigers killed more livestock, possibly because livestock were more easily accessible than wild prey. Our results show that open-access and unregulated livestock grazing is not currently compatible with large carnivore conservation in the same landscape. Such practices will lead to an increase in negative tiger-human-livestock interactions. In conclusion, we suggest the need to encourage locals to corral valuable cattle, leaving feral/unwanted livestock for tigers. This simple strategy would benefit both local inhabitants and tiger conservation in the multiple-use forests of India.

Setting aside protected areas is a key strategy for tackling biodiversity loss. Reserve effectiveness depends on the extent to which protected areas capture both known occurrences and areas likely to support the species. We assessed the effectiveness of the existing reserve network for Leadbeater's Possum (Gymnobelideus leadbeateri) and other forest-dependent species, and compared the existing reserve system to a set of plausible reserve expansion options based on area targets implied in a recent Population Viability Analysis (PVA). The existing Leadbeater's Reserve and surrounding reserve system captured 7.6% and 29.6% of cumulative habitat suitability, respectively, across the landscape. Expanded reserve scenarios captured 34% to 62% of cumulative habitat suitability. We found acute trade-offs between conserving Leadbeater's Possum habitat and conserving habitat of other forest-dependent species. Our analysis provides a template for systematically expanding and evaluating reserve expansion options in terms of trade-offs between priority species' needs.

Competition law and the obligation to supply

DEFF Research Database (Denmark)

Bergqvist, Christian

2015-01-01

While accepted in theory and practice that an obligation to supply, ser-vice or license can emerge under competition law, the scope of this is subject to many, if not lacunas, at least ambiguities, and no general ob-li¬gations of such nature can, no should, be identified. Further, and equally...... important, the narrow set of circumstances warranting inter-vention against refusals is defined by competition law in accordance with its underlying principles of a predominantly economic nature. Hence, competition law should not be relied upon as a corrective in-strument to lacunas in other areas of law, e.......g. compulsory licenses un-der IP law. Below, some considerations regarding the obligation to supply under competition law are offered for the purpose of correcting the misunderstandings....

Full Text Available In its essence, post-trial obligations describe a duty by research sponsors to provide a successfully tested drug to research participants who took part in the relevant clinical trials after the trial has been concluded. In some instances, this duty is extended beyond the research participants. This article is divided into three main parts. The first part outlines the legal basis for post-trial obligations by looking at international guidelines, including those issued by the World Medical Association. National legislation is exemplified through resolutions and guidelines issued by Brazil and South Africa respectively. The second part analyses the ethical foundation for post-trial obligations, in particular the attempt to minimize exploitation of research subjects. The third part raises obstacles and challenges for the implementation of post-trial obligations. The jury is still out on whether post-trial obligations in the form of access to drugs for clinical trial participants is the best, or even a good way, to avoid exploitation in medical research.

The evaluation of naturalness used the historical data concerning the wood extraction, as were recorded in the forest management plans. In selected stands of higher local naturalness was further conducted an inventory, following the methodology recommended by COST E4 and based on a systematic grid with circular plots of 500 m2 . Expected, the results showed that extraction impacted the structural characteristics of stands, esspecially the standing/downing trees volume. The comparison of structural data resulted from inventory (density and volume of both alive and dead standing trees and coarse woody debris with local references - “virgin“ forests located about 40 km apart of the forest reserves under study - suggested a degree of correspondence between 20-40%. The same data, compared with published information available from mixed forest of beech-fir-spruce accross temperate zone of Europe confirmed the departure of selected stands from the references of naturalness and their distinct grouping, compared with other forest reserves.

Carbon Storage Potential of Forest Land: A Comparative Study of Cases in Finland and Croatia

Martina Tijardović

2013-06-01

Full Text Available Background and Purpose: The concentrations of greenhouse gases in the atmosphere have been increasing over the last hundred years in relation to the Fourth IPCC assessment report that highlighted human activities as a direct influence on climate changes. Since Croatia and Finland signed the Kyoto Protocol, they are both committed to fulfil international obligations of lowering GHG’s emissions, enhancing the storage, as well as protecting and enhancing the current pools where the forestry sector has a prominent role. These obligations created a need for a review on carbon storage potentials for both countries with the aim of setting further scientific and management guidelines as the basic purpose of this research. Materials and Methods: Data collection was conducted within the scope of the Sort Term Scientific Mission (STSM in the period from May 2 – July 22, 2009 in the Finnish Forest Research Institute in Joensuu. The research encompassed an overview of literature, personal contacts with scientists and experts from both countries (research institutes, ministries, the EFI branch office in Joensuu and a field inspection which altogether provided an insight into the applied silvicultural and utilization activities. A significant data source were official documents and published project results on the carbon storage potential. Results and Discussion: Mitigation activities within the framework of the LULUCF project reduced the total emissions for 33.4 millions tons of CO2 equivalents in Finland in 2006 (this data has varied from 18 to 33.4 millions tons CO2 equivalents in the last fifteen years while for Croatia the availability of such data is limited. Finland has some former agricultural land which may be afforested but not in the substantial share, while in Croatia such areas amount to around 1 million ha.

The implications of new forest tenure reforms and forestry property markets for sustainable forest management and forest certification in China.

Science.gov (United States)

Chen, Juan; Innes, John L

2013-11-15

This study examines issues existing in the southern collective forests in China, particularly prior to the implementation of new forest tenure reforms, such as continued illegal logging and timber theft, inadequate availability of finance and inconsistent forest-related policies. Such problems are believed to be hindering the adoption of sustainable forest management (SFM) and forest certification by forest farmers in China. Two strategies were introduced by the Chinese government with the purpose of addressing these issues, namely forest tenure reforms and their associated supporting mechanism, forestry property markets. Through two case studies in southern China, we investigated the effectiveness of the two strategies as well as their implications for the adoption of SFM and forest certification. The two cases were Yong'an in Fujian province and Tonggu in Jiangxi province. Personal interviews with open-ended questions were conducted with small-scale forest farmers who had already benefited from the two strategies as well as market officers working for the two selected forestry property markets. The study identified eight issues constraining the potential adoption of SFM and certification in China, including limited finance, poorly developed infrastructure and transport systems, insecure forest tenures, inconsistent forest policies, low levels of awareness, illegal forest management practices, lack of local cooperative organizations, and inadequate knowledge and technical transfer. We found that the new forest tenure reforms and forestry property markets had generally fulfilled their original objectives and had the capacity to assist in addressing many of the issues facing forests prior to the reforms.

Anthropogenic disturbances jeopardize biodiversity conservation within tropical rainforest reserves.

Science.gov (United States)

Martínez-Ramos, Miguel; Ortiz-Rodríguez, Iván A; Piñero, Daniel; Dirzo, Rodolfo; Sarukhán, José

2016-05-10

Anthropogenic disturbances affecting tropical forest reserves have been documented, but their ecological long-term cumulative effects are poorly understood. Habitat fragmentation and defaunation are two major anthropogenic threats to the integrity of tropical reserves. Based on a long-term (four decades) study, we document how these disturbances synergistically disrupt ecological processes and imperil biodiversity conservation and ecosystem functioning at Los Tuxtlas, the northernmost tropical rainforest reserve in the Americas. Deforestation around this reserve has reduced the reserve to a medium-sized fragment (640 ha), leading to an increased frequency of canopy-gap formation. In addition, hunting and habitat loss have caused the decline or local extinction of medium and large herbivores. Combining empirical, experimental, and modeling approaches, we support the hypothesis that such disturbances produced a demographic explosion of the long-lived (≈120 y old, maximum height of 7 m) understory palm Astrocaryum mexicanum, whose population has increased from 1,243-4,058 adult individuals per hectare in only 39 y (annual growth rate of ca 3%). Faster gap formation increased understory light availability, enhancing seed production and the growth of immature palms, whereas release from mammalian herbivory and trampling increased survival of seedlings and juveniles. In turn, the palm's demographic explosion was followed by a reduction of tree species diversity, changing forest composition, altering the relative contribution of trees to forest biomass, and disrupting litterfall dynamics. We highlight how indirect anthropogenic disturbances (e.g., palm proliferation) on otherwise protected areas threaten tropical conservation, a phenomenon that is currently eroding the planet's richest repositories of biodiversity.

Facing the problem of the climatic change and the increase of the fossil energies prices, the government policy of the cogeneration development follows many objectives. Among these objectives it is necessary of implement a new tariff of obligation to buy of the electricity from cogeneration and allow the existing installations to reaffirm their obligation to buy contract. The first part of this report defines the necessary conditions to better use the ecological and economical interest of the natural gas cogeneration and shows that these conditions are not favorable in France. The second part preconizes to modify the actual tariff device in order to maintain the existing park to 2015 in acceptable economical and ecological conditions. (A.L.B.)

The 'special obligations' of the modern Hippocratic Oath for 21st century medicine.

Science.gov (United States)

Holmboe, Eric; Bernabeo, Elizabeth

2014-01-01

Profound advances and discoveries in medicine have markedly improved the lives of many over the 50 years since the modern Hippocratic Oath was written. Regrettably, these advances were and continue to be implemented suboptimally and inequitably across the globe. 'Special obligations to all my fellow humans' is an important theme of the modern Oath. From this perspective, we reflect on the special obligations of the medical profession, and examine how these obligations have changed over the past 50 years. We draw from perspectives of the social contract, professionalism, quality improvement, patient safety and a group of 31 international colleagues involved in medical education as we examine these obligations for individual doctors, health care institutions and medical education systems. The perspectives of the 31 clinician-educators helped us to situate the meaning of the theme of 'special obligations' in the context of challenges facing medical education and health care in the 21st century. Improving the quality of care and patient safety, and reducing health care disparities are now paramount as 'special obligations' for doctors, health care systems and medical education organisations, and require us to work collectively and collaboratively in an increasingly interconnected world. In our view, traditions such as the Hippocratic Oath will be worthy of public support only when the medical profession demonstrates in meaningful and transparent ways that it is meeting its social and civic obligations to make the world, not just health care, a better place. © 2013 John Wiley & Sons Ltd.

Why patients have a moral obligation to give care to clinicians.

Science.gov (United States)

Buetow, Stephen

2014-12-01

Progress is being made in transitioning from clinicians who are torn between caring for patients and populations, to clinicians who are partnering with patients to care for patients as people. However, the focus is still on what patients and others can do for patients, however defined. For clinicians whose interests must be similarly respected for their own sake and because they are integrally related to those of patients, what can and should patients do? Patients can be exempted from some normal social roles but are generally recognized to have moral obligations in health care. One of these obligations is caregiving to clinicians within the limits of each patient's capability. My paper moves this obligation beyond the ceremonial order of etiquette characterizing public statements on how patients should relate to others. It goes beyond a patient-centred ethic that is consumerist in nature, to a person-centred one that recognizes patients typically as moral agents who are dignified by recognizing the obligation to give as well as receive care as sincere benevolence. This obligation derives objective justification from divine command. It is also consistent, however, both with what people, if ignorant of their social role, would objectively produce for a hypothetical social contract, and with virtues constitutive of human nature and a relational and communitarian understanding of what it is to be a person. Including sentiment (intuition) and personal conscience, this relational identity makes caregiving intrinsically meaningful, yet caregiving also has an instrumental value to patients and clinicians. Its self-enforcement by patients will depend on their moral code and on society making caregiving achievable for them. A moral obligation for patient caregiving may then be specified to require patients to reflect on and invest in relationships in which they can feel and show care for others sincerely and respectfully. © 2014 John Wiley & Sons, Ltd.

SPECIES EXTINCTION IN PROTECTED AREAS (VORONEZH RESERVE, 1935–2015

2016-12-01

Full Text Available Background. The study of long-term dynamics of reserves vegetation indicates the presence of the problems with biological diversity conservation in the protected areas. It emerged in the territories violated by the previous economic activity. The losses in the flora of vascular plants of the Voronezh State Reserve for the protected period were estimated, the reasons for the disappearance of species were identified. The aim of the work was to determine the necessity and the possibility of changing management strategies for conserving floristic diversity of the reserve. Materials and methods. The list of flora, created at the stage of nature reserve creation , included 922 species. 13 eco-cenotic groups are identified in the autochthonous flora Voronezh Reserve, all alien species are combined into a group of adventitious plants. To evaluate the floristic losses we made analysis of all floristic and geobotanical materials published and stored in the nature reserve, as well as the article author’s data obtained during the area survey in 1985–2016. To identify the factors and processes determining the dynamics of the flora, we used materials on the history of people activity before the reserve and during the protected period, as well as published research on the reserve vegetation dynamics. Results. The disappearance of 55 vascular plants species is established as a result of long-term monitoring of Voronezh State Reserve flora. 23 adventive species and 32 autochthonous species disappeared from the flora composition over 80 years of the Reserve existence. The most vulnerable from a position of floral diversity loss are light-loving species groups associated with waterlogging ecotopes (sphagnum-oligotrophic, swamp-grass and boreal groups, as well as dry pine forests and open habitats (pine forest group, psammophilous, dry-meadow-steppe and wet meadow groups. The reasons of floristic losses are: 1 autogenic succession, leading to the replacement of

Assignments of rights and obligations under a gas sales contract

International Nuclear Information System (INIS)

Kowch, J.R.M.

1996-01-01

A general overview of the principles of assignment in a gas sales contract was presented. Assignment is a process wherein the rights or obligations under a contract are transferred from one of the contracting parties to a third party. It is, in other words, the introduction of a new party to the original contractual relationship. Under the rights and obligations of a gas sales contract, the most important right of the seller is to have its gas taken and to be paid. Likewise, the most important obligation of the buyer is to take the gas and pay for it. An assignment by either party has the potential to alter the original expectations of the parties or the basis of which they committed to the contract in the first place. Prior to deregulation and unbundling initiatives, gas sellers and buyers could enter a 20 year sales contract and deal exclusively with each other over the entire 20 year term. Since deregulation, there are more players, and a higher level of corporate acquisitions, divestitures, rationalizations, and restructuring. Today, there are greater chances than ever before that the original party to a contract may change, or that certain rights and obligations may be assigned to a third party and affect the expectations under the contract

Global Redistributive Obligations in the Face of Severe Poverty

? In the debate on global justice, a number of theorists argue that this discrepancy can indeed be justified (so-called anti-cosmopolitans). Thus, to bring us closer to answer regarding our redistributive obligations towards foreigners, I analyze and evaluate such arguments. My critical examination reveals...... comprehensive obligations to foreigners and compatriots simultaneously. Thus, even if we are duty-bound to redistribute comprehensively to compatriots, this does not entail that we could not also do so towards non-compatriots. Hence, their arguments are incomplete. Thirdly, I show that anti...

Comparative assessment of public opinion on the landscape quality of two biosphere reserves in Europe.

Science.gov (United States)

Sowińska-Świerkosz, Barbara; Chmielewski, Tadeusz J

2014-09-01

The European Landscape Convention (2000) obligates European Union countries to identify and implement landscape quality objectives (LQOs) understood as the specification of public expectations and preferences concerning the landscape of a given area, expressed by competent public authorities. The convention emphasizes the important role of local community representatives in this field. In Poland, the implementation of the LQO concept was first undertaken in two regions with radically different landscape characteristics: (1) the West Polesie Biosphere Reserve and (2) the selected protected areas of the Roztocze-Solska Forest, nominated to the rank of a biosphere reserve. The first stage of the presented study was the recognition of public opinion on the quality of key features of landscape, based on a questionnaire (n = 470). The primary objective of the study was to provide an answer to the following questions: (1) Whether similar social expectations regarding landscape quality exist in spite of radically different landscape characteristics of the regions investigated (landscape quality is understood as spatial arrangement, scenic beauty, and lack of environmental pollution); (2) which landscape features are considered to be most preservation worthy by the representatives of both local communities; and (3) What processes or development impacts pose the greatest threat to the landscape quality of both regions according to the public opinion? The conducted comparative assessment revealed that it is possible to define a set of features fundamental to the quality of both areas and that representatives of local communities pointed out the same threats to the natural and cultural values of both regions investigated.

Advances of air pollution science: from forest decline to multiple-stress effects on forest ecosystem services.

2010-06-01

Over the past 20 years, the focus of forest science on air pollution has moved from forest decline to a holistic framework of forest health, and from the effects on forest production to the ecosystem services provided by forest ecosystems. Hence, future research should focus on the interacting factorial impacts and resulting antagonistic and synergistic responses of forest trees and ecosystems. The synergistic effects of air pollution and climatic changes, in particular elevated ozone, altered nitrogen, carbon and water availability, must be key issues for research. Present evidence suggests air pollution will become increasingly harmful to forests under climate change, which requires integration amongst various stressors (abiotic and biotic factors, including competition, parasites and fire), effects on forest services (production, biodiversity protection, soil protection, sustained water balance, socio-economical relevance) and assessment approaches (research, monitoring, modeling) to be fostered.

Reserves protect against deforestation fires in the Amazon.

Directory of Open Access Journals (Sweden)

J Marion Adeney

Full Text Available BACKGROUND: Reserves are the principal means to conserve forests and biodiversity, but the question of whether reserves work is still debated. In the Amazon, fires are closely linked to deforestation, and thus can be used as a proxy for reserve effectiveness in protecting forest cover. We ask whether reserves in the Brazilian Amazon provide effective protection against deforestation and consequently fires, whether that protection is because of their location or their legal status, and whether some reserve types are more effective than others. METHODOLOGY/PRINCIPAL FINDINGS: Previous work has shown that most Amazonian fires occur close to roads and are more frequent in El Niño years. We quantified these relationships for reserves and unprotected areas by examining satellite-detected hot pixels regressed against road distance across the entire Brazilian Amazon and for a decade with 2 El Niño-related droughts. Deforestation fires, as measured by hot pixels, declined exponentially with increasing distance from roads in all areas. Fewer deforestation fires occurred within protected areas than outside and the difference between protected and unprotected areas was greatest near roads. Thus, reserves were especially effective at preventing these fires where they are known to be most likely to burn; but they did not provide absolute protection. Even within reserves, at a given distance from roads, there were more deforestation fires in regions with high human impact than in those with low impact. The effect of El Niño on deforestation fires was greatest outside of reserves and near roads. Indigenous reserves, limited-use reserves, and fully protected reserves all had fewer fires than outside areas and did not appear to differ in their effectiveness. CONCLUSIONS/SIGNIFICANCE: Taking time, regional factors, and climate into account, our results show that reserves are an effective tool for curbing destructive burning in the Amazon.

The effects of forest structure on occurrence and abundance of three owl species (Aves: Strigidae in the Central Amazon forest

Directory of Open Access Journals (Sweden)

Obed G. Barros

2009-03-01

Full Text Available We investigated how forest structure affects the occurrence and abundance of three owl species: the crested owl Lophostrix cristata Daudin, 1800, the Amazon pygmy owl Glaucidium hardyi Vielliard, 1990, and the tawny-bellied screech owl Megascops watsonii Cassin, 1849. We surveyed the owls mostly between 07:00 and 11:00 pm from July 2001 to April 2002, in eighteen 8 km transects along trails at the Ducke Reserve, Manaus, Central Amazon, Brazil. We staked out 50 x 50 m plots where the presence and absence of the owls were recorded. We compared some components of the forest structure between plots where owls were present and plots where they were absent. The spatial variation in these components were related to the occurrence and abundance of the owls using models of multiple logistic and multiple linear regressions analysis, respectively. Lophostrix cristata is rare in many other areas of the Amazon forest, but it was the most abundant in our study area. Lophostrix cristata and G. hardyi were more concentrated along the uplands (central plateau, which divide the reserve into two drainage water-basins. Megascops watsonii was distributed mainly in the southeastern part of the reserve. Glaucidium hardyi was more often found in areas with larger canopy openness. In areas with higher abundance of snags, there was significantly higher occurrence of L. cristata and M. watsonii. Megascops watsonii was also more abundant in areas with higher abundance of forest trees and in areas bearing shallower leaf litter on the forest floor. This study is the first to analyze at large spatial scale the effects of forest structure on neotropical forest top predator nocturnal birds. The results indicate that forest structure can affect the occurrence and abundance of owls in the Amazon forest.

A cross-cultural study of noblesse oblige in economic decision-making.

2013-09-01

A cornerstone of economic theory is that rational agents are self-interested, yet a decade of research in experimental economics has shown that economic decisions are frequently driven by concerns for fairness, equity, and reciprocity. One aspect of other-regarding behavior that has garnered attention is noblesse oblige, a social norm that obligates those of higher status to be generous in their dealings with those of lower status. The results of a cross-cultural study are reported in which marked noblesse oblige was observed on a reciprocal-contract decision-making task. Participants from seven countries that vary along hierarchical and individualist/collectivist social dimensions were more tolerant of non-reciprocation when they adopted a high-ranking perspective compared with a low-ranking perspective.

Data on macrofungal diversity from the Danube Delta iosphere Reserve

Full Text Available Despite de fact that the Danube Delta has a great biodiversity with more than 2300 plants and more than 4000 animals registered (http://www.ddbra.ro/rezervatia/deltadunarii/biodiversitate, the study of macromycetes is rather scanty, and the number of macromycetes species found so far in the Reserve is 58. As a result of the mycological investigations done by the authors in 2016 May 7-8 and October 21-22 in the Danube Delta Biosphere Reserve in the Letea Forest, Caraorman Forest and at the forest district’s former premises near C.A. Rosetti, the list of the recorded 130 species is presented, out of which 110 species are documented for the first time in the Danube Delta Biosphere Reserve (DDBR. The number of the macrofungi species that occur in the formentioned Reserve - including the buffer zone from Enisala - has grown to 168. Based on the red list of the romanian macromycetes (Tănase and Pop, 2005 we have found three species in the near threatened category (NT: Helvella acetabulum, Morchella esculenta and Pluteus petasatus, and one species in the vulnerable category (VU: Myriostoma coliforme. A short survey from 1932 to 2012 about the former mycological studies concerning the DDBR is presented, and the nomenclaturally updated list of the 38 species not found by us, but present in the DDBR is given.

Full Text Available A detailed analysis ot the flora of the newly proclaimed Kap River Reserve (600 ha is given. The reserve is adjacent to the Fish River and some 5 km from the Fish River Mouth It consists of a coastal plateau up to 100 m a.s.I. which is steeply dissected by the two rivers that partially form the boundary of the reserve. The flora of the reserve was sampled over a period o f three years and plants were collected in all the vegetation types of grassland, thicket and forest. 488 species were collected with a species to family ratio of 4:4. The majority of the taxa recorded represent the major phytochoria of the region. Nineteen species are endemic to the Eastern Cape, two are classed as vulnerable, five are rare, six are protected and a further seventeen are of uncertain status. The flora of the Kap River has closest affinities to that of the Alexandria Forest.

A number of Member States of the European Union (EU) have introduced market-based policy portfolios based on quantified energy savings obligations on energy distributors or suppliers, possibly coupled with certification of project-based energy savings (via white certificates), and the option to trade the certificates or obligations. The paper provides an up-to-date review and analysis of results to date of white certificate schemes in the EU. In the EU supplier obligations and white certificate schemes have delivered larger savings than originally expected with obliged companies exceeding targets and, in some cases, at cost below what policy makers have anticipated. Supplier obligations foster the uptake of standardised energy efficiency actions often targeting smaller energy users (residential sector), lowering the transaction costs and contributing to market transformation. The role of certificate trading is more ambiguous. Trading can bring benefits where the target is set sufficiently high with respect to the energy-saving potential in the sectors covered. Theoretically trading may be better suited for broader systems with comprehensive coverage, but even in smaller schemes trading may reduce the transaction costs of compliance for obliged actors without sufficient expertise on end-use energy efficiency. Yet, trading increases the administrative cost ratio of energy-saving obligations.

Facing the problem of the climatic change and the increase of the fossil energies prices, the government policy of the cogeneration development follows many objectives. Among these objectives it is necessary of implement a new tariff of obligation to buy of the electricity from cogeneration and allow the existing installations to reaffirm their obligation to buy contract. The first part of this report defines the necessary conditions to better use the ecological and economical interest of the natural gas cogeneration and shows that these conditions are not favorable in France. The second part preconizes to modify the actual tariff device in order to maintain the existing park to 2015 in acceptable economical and ecological conditions. (A.L.B.)

Support Seeking or Familial Obligation: An Investigation of Motives for Disclosing Genetic Test Results.

Science.gov (United States)

Greenberg, Marisa; Smith, Rachel A

2016-01-01

Genetic test results reveal not only personal information about a person's likelihood of certain medical conditions but also information about the person's genetic relatives. Given the familial nature of genetic information, one's obligation to protect family members may be a motive for disclosing genetic test results, but this claim has not been methodically tested. Existing models of disclosure decision making presume self-interested motives, such as seeking social support, instead of other-interested motives, like familial obligation. This study investigated young adults' (N = 173) motives to share a genetic-based health condition, alpha-1 antitrypsin deficiency, after reading a hypothetical vignette. Results show that social support and familial obligation were both reported as motives for disclosure. In fact, some participants reported familial obligation as their primary motivator for disclosure. Finally, stronger familial obligation predicted increased likelihood of disclosing hypothetical genetic test results. Implications of these results were discussed in reference to theories of disclosure decision-making models and the practice of genetic disclosures.

Windthrow and fallow-forest successions impacts in soil carbon stocks and GHG fluxes spatial variability and dynamics in the Central Russia' reserve spruce ecosystems

High spatial and temporal variability is mutual feature for most forest soils that is especially obvious in case of their carbon stocks and GHG fluxes. This phenomenon is generally well-known but not so often becomes the object of special precision investigation in detail and small scales so there are still serious gaps in its principal factors understanding due to their high bioclimatic, regional, landscape, tree species and temporal variability. Southern taiga is one of the most environmentally important world zonal forest ecosystems due to its still comparatively intensive carbon biogeochemical cycle and huge area in the northern Eurasia with strong anthropogenic impacts by Western & Central European and Southern & Eastern Asian regions. Central Forest Biospheric Reserve (Tver region, 360 km to North-West from Moscow) is the principal southern-taiga reserve in the European territory of Russia. Since start of its research activity in 1939 the reserve became the regional center of mature spruce ecosystem structure and dynamics investigation. In 1970-1980-s there have been done complex investigations of windthrow soil patterns and fallow-forest successions. Since middle of 1990-s the ecosystem-level GHG fluxes have been observed by eddy covariance method. Since 2012 the detailed year-round monitoring is running in the southern-taiga zonal station of the regional system RusFluxNet with especial attention on the soil carbon stocks and GHG fluxes spatial variability and dynamics due to windthrow and fallow-forest successions (in frame of RF Governmental projects #11.G34.31.0079 and #14.120.14.4266). Soil carbon dynamics is investigated in decades-hundred-year chronosequences of dominated parcels and different-size windthrow soil cover patterns, including direct investigation during last 33 years with detailed mapping, soil profile morphometrics and bulk density, morphogenetic and statistical analysis of mass data.

Full Text Available En droit français, le reclassement des salariés a émergé dans des hypothèses précises et, dans la plupart des cas, sous l’impulsion des hautes juridictions, Cour de cassation ou Conseil d’État. Le législateur est intervenu a posteriori pour consacrer une obligation de reclassement déjà dégagée en jurisprudence ou en germe. Le contexte dans lequel cette obligation s’est construite permet d’expliquer ce qui caractérise son champ d’application. L’emploi, plus exactement la préservation du lien d’emploi, y joue un rôle central et fédérateur. Mais à la différence du droit québécois, la discrimination reste distincte et même si son champ recoupe celui de l’obligation de reclassement, on ne peut intégrer celle-ci dans celle-là. Ces constats permettent d’orienter la recherche des fondements juridiques de l’obligation de reclassement. Plus que sur une analyse de droit des contrats, quand bien même celle-ci serait renouvelée, l’obligation de reclassement peut s’appuyer sur un droit de valeur constitutionnel : le droit d’obtenir un emploi. À l’échelle des règles internationales, ce dernier peut également s’adosser à plusieurs textes, dont un s’est vu reconnaître une portée considérable en droit français.In French law, worker reclassification emerged under precise assumptions and, in most cases, under the impetus of the high jurisdictions, the Cour de Cassation or the Conseil d’Etat. The legislator intervened a posteriori to legitimize a reclassification obligation already emerging in jurisprudence or in the process of being created. The context in which this obligation was built makes it possible to explain what characterizes its field of application. Employment, or more exactly the safeguarding of employment, plays a central and federator role in it. But unlike Quebec law, discrimination remains distinct and even if its field transects that of the reclassification obligation, it cannot

photographic mosaic of the sampling area. The unassisted and assisted spectral classification technique was carried out in the ERDAS Imagine image-processing software package. For the unassisted classification, tests were carried out considering various numbers of categories: 5, 10 and 15; the assisted classification included the spectral properties of each category used for the partition to group images into five categories: healthy forest, diseased forest, Juniperus scrubland, bare soil and shaded areas. The accuracy of the technique for the detection of damaged trees was verified through field work, visiting different checkpoints where the health status of the tree was corroborated by direct observation and infrared photography at ground level. A representative sampling area of the A. religiosa forest was established in the Monarch Butterfly Biosphere Reserve (RBMM, sufficient to encompass the largest number of damaged trees, but not so large as to excessively prolong the information-processing phases and make field sampling unattainable.  The analysis comprised an area of 1907 ha in Sierra Chincua, where the greatest affectation was observed in a core zone including 97 points (62% with more than twice the density of individuals (11 trees/km2, relative to the buffer zone (4 trees/km2. This greater damage is the result of forest management policies, which have set no management (including sanitation in the core zone. At the end of this research work, we concluded that digital aerial photographs proved useful for the detection of damaged trees in Abies religiosa forests of RBMM. It is possible to obtain multispectral images using a low-cost photographic technology that is relatively simple and widely available. Our study showed that the best method to detect damage in A. religiosa forests in RBMM is the visual interpretation of aerial photographs, yielding a detection efficiency of over 98%. The method used has a greater costeffectiveness compared to helicopter overflight

We review patterns and processes important for biodiversity in the Fennoscandian boreal forest, describe man's past and present impact and outline a strategy for conservation. Natural disturbances, particularly forest fire and gap formation, create much of the structural and functional diversity in forest ecosystems. Several boreal plants and animals are adapted to fire regimes. In contrast, many organisms (epiphytic lichens, fungi, invertebrates) require stable conditions with long continuity in canopy cover. The highly mechanized and efficient Fennoscandian forest industry has developed during the last century. The result is that most natural forest has been lost and that several hundreds of species, mainly cryptograms and invertebrates, are threatened. The forestry is now in a transition from exploitation to sustainable production and has recently incorporated some measures to protect the environment. Programmes for maintaining biodiversity in the boreal forest should include at least three parts. First, the system of forest reserves must be significantly improved through protection of large representative ecosystems and key biotopes that host threatened species. Second, we must restore ecosystem properties that have been lost or altered. Natural disturbance regimes must be allowed to operate or be imitated, for example by artificial fire management. Stand-level management should particularly increase the amount of coarse woody debris, the number of old deciduous trees and large, old conifers, by using partial cutting. Third, natural variation should also be mimicked at the landscape level, for example, by reducing fragmentation and increasing links between landscape elements. Long-term experiments are required to evaluate the success of different management methods in maintaining biodiversity in the boreal forest. (au) 260 refs

A de-novo-assembly-based Data Analysis Pipeline for Plant Obligate Parasite Metatranscriptomic Studies

Full Text Available Current and emerging plant diseases caused by obligate parasitic microbes such as rusts, downy mildews, and powdery mildews threaten worldwide crop production and food safety. These obligate parasites are typically unculturable in the laboratory, posing technical challenges to characterize them at the genetic and genomic level. Here we have developed a data analysis pipeline integrating several bioinformatic software programs. This pipeline facilitates rapid gene discovery and expression analysis of a plant host and its obligate parasite simultaneously by next generation sequencing of mixed host and pathogen RNA (i.e. metatranscriptomics. We applied this pipeline to metatranscriptomic sequencing data of sweet basil (Ocimum basilicum and its obligate downy mildew parasite Peronospora belbahrii, both lacking a sequenced genome. Even with a single data point, we were able to identify both candidate host defense genes and pathogen virulence genes that are highly expressed during infection. This demonstrates the power of this pipeline for identifying genes important in host-pathogen interactions without prior genomic information for either the plant host or the obligate biotrophic pathogen. The simplicity of this pipeline makes it accessible to researchers with limited computational skills and applicable to metatranscriptomic data analysis in a wide range of plant-obligate-parasite systems.

Successful invaders must overcome biotic resistance, which is defined as the reduction in invasion success caused by the resident community. Soil microbes are an important source of community resistance to plant invasions, and understanding their role in this process requires urgent investigation. Therefore, three forest communities along successional stages and four exotic invasive plant species were selected to test the role of soil microbes of three forest communities in resisting the exotic invasive plant. Our results showed that soil microbes from a monsoon evergreen broadleaf forest (MEBF) (late-successional stage) had the greatest resistance to the invasive plants. Only the invasive species Ipomoea triloba was not sensitive to the three successional forest soils. Mycorrhizal fungi in early successional forest Pinus massonina forest (PMF) or mid-successional forest pine-broadleaf mixed forest (PBMF) soil promoted the growth of Mikania micrantha and Eupatorium catarium, but mycorrhizal fungi in MEBF soil had no significant effects on their growth. Pathogens plus other non-mycorrhizal microbes in MEBF soil inhibited the growth of M. micrantha and E. catarium significantly, and only inhibited root growth of E. catarium when compared with those with mycorrhizal fungi addition. The study suggest that soil mycorrhizal fungi of early-mid-successional forests benefit invasive species M. micrantha and E. catarium, while soil pathogens of late-successional forest may play an important role in resisting M. micrantha and E. catarium. The benefit and resistance of the soil microbes are dependent on invasive species and related to forest succession. The study gives a possible clue to control invasive plants by regulating soil microbes of forest community to resist plant invasion.

Japan introduced a nationwide long-term care insurance (LTCI) system in 2000, making long-term care (LTC) a right for older adults regardless of income and family availability. To shed light on its implications for family caregiving, we investigated perceived filial obligation norms among coresident primary family caregivers before and after the policy change. Descriptive and multiple regression analyses were conducted to examine changes in perceived filial obligation norms and its subdimensions (financial, physical, and emotional support), using 2-wave panel survey data of coresident primary family caregivers (N = 611) in 1 city. The baseline survey was conducted in 1999, and a follow-up survey 2 years later. On average, perceived filial obligation norms declined (p family caregivers. In particular, physical support, which Japan's LTC reform targeted, declined significantly among daughters and daughters-in-law (p perceived filial obligation norms after the policy introduction than sons and daughters (p < .01 and p < .05, respectively), controlling for the baseline filial obligation and situational factors. Our research indicates declining roles of daughters-in-law in elder care during Japan's LTCI system implementation period. Further international efforts are needed to design and implement longitudinal studies that help promote understanding of the interplay among national LTC policies, social changes, and caregiving norms and behaviors. © The Author 2013.

Although many examples of multiple-use forest management may be found in tropical smallholder systems, few studies provide empirical support for the integration of selective timber harvesting with non-timber forest product (NTFP) extraction. Brazil nut (Bertholletia excelsa, Lecythidaceae) is one of the world’s most economically-important NTFP species extracted almost entirely from natural forests across the Amazon Basin. An obligate out-crosser, Brazil nut flowers are pollinated by large-bodied bees, a process resulting in a hard round fruit that takes up to 14 months to mature. As many smallholders turn to the financial security provided by timber, Brazil nut fruits are increasingly being harvested in logged forests. We tested the influence of tree and stand-level covariates (distance to nearest cut stump and local logging intensity) on total nut production at the individual tree level in five recently logged Brazil nut concessions covering about 4000 ha of forest in Madre de Dios, Peru. Our field team accompanied Brazil nut harvesters during the traditional harvest period (January-April 2012 and January-April 2013) in order to collect data on fruit production. Three hundred and ninety-nine (approximately 80%) of the 499 trees included in this study were at least 100 m from the nearest cut stump, suggesting that concessionaires avoid logging near adult Brazil nut trees. Yet even for those trees on the edge of logging gaps, distance to nearest cut stump and local logging intensity did not have a statistically significant influence on Brazil nut production at the applied logging intensities (typically 1–2 timber trees removed per ha). In one concession where at least 4 trees ha-1 were removed, however, the logging intensity covariate resulted in a marginally significant (0.09) P value, highlighting a potential risk for a drop in nut production at higher intensities. While we do not suggest that logging activities should be completely avoided in Brazil nut rich

The etiology of veterinary infectious diseases has been the focus of considerable research, yet relatively little is known about the causative agents of anaerobic infections. Susceptibility studies have documented the emergence of antimicrobial resistance and indicate distinct differences in resistance patterns related to veterinary hospitals, geographic regions, and antibiotic-prescribing regimens. The aim of the present study was to identify the obligate anaerobic bacteria from veterinary clinical samples and to determinate the in vitro susceptibility to eight antimicrobials and their resistance-associated genes. 81 clinical specimens obtained from food-producing animals, pets and wild animals were examined to determine the relative prevalence of obligate anaerobic bacteria, and the species represented. Bacteroides spp, Prevotella spp and Clostridium spp represented approximately 80% of all anaerobic isolates. Resistance to metronidazole, clindamycin, tetracycline and fluoroquinolones was found in strains isolated from food-producing animals. Ciprofloxacin, enrofloxacin and cephalotin showed the highest resistance in all isolates. In 17%, 4% and 14% of tetracycline-resistant isolates, the resistance genes tetL, tetM and tetW were respectively amplified by PCR whereas in 4% of clindamycin-resistant strains the ermG gene was detected. 26% of the isolates were positive for cepA, while only 6% harbored the cfxA (resistance-conferring genes to beta-lactams). In this study, the obligate anaerobic bacteria from Costa Rica showed a high degree of resistance to most antimicrobials tested. Nevertheless, in the majority of cases this resistance was not related to the resistance acquired genes usually described in anaerobes. It is important to address and regulate the use of antimicrobials in the agricultural industry and the empirical therapy in anaerobic bacterial infections in veterinary medicine, especially since antibiotics and resistant bacteria can persist in the

Redefining Secondary Forests in the Mexican Forest Code: Implications for Management, Restoration, and Conservation

Directory of Open Access Journals (Sweden)

Francisco J. Román-Dañobeytia

2014-05-01

Full Text Available The Mexican Forest Code establishes structural reference values to differentiate between secondary and old-growth forests and requires a management plan when secondary forests become old-growth and potentially harvestable forests. The implications of this regulation for forest management, restoration, and conservation were assessed in the context of the Calakmul Biosphere Reserve, which is located in the Yucatan Peninsula. The basal area and stem density thresholds currently used by the legislation to differentiate old-growth from secondary forests are 4 m2/ha and 15 trees/ha (trees with a diameter at breast height of >25 cm; however, our research indicates that these values should be increased to 20 m2/ha and 100 trees/ha, respectively. Given that a management plan is required when secondary forests become old-growth forests, many landowners avoid forest-stand development by engaging slash-and-burn agriculture or cattle grazing. We present evidence that deforestation and land degradation may prevent the natural regeneration of late-successional tree species of high ecological and economic importance. Moreover, we discuss the results of this study in the light of an ongoing debate in the Yucatan Peninsula between policy makers, non-governmental organizations (NGOs, landowners and researchers, regarding the modification of this regulation to redefine the concept of acahual (secondary forest and to facilitate forest management and restoration with valuable timber tree species.

Pricing in quota obligation schemes for renewable energy. A stochastic model with reference to the Swedish quota obligation; Preisbildung in Quotenmodellen zur Foerderung Erneuerbarer Energien. Modellierung mit stochastischem Ansatz am Beispiel des schwedischen Quotenmodells

Energy Technology Data Exchange (ETDEWEB)

Dees, Philipp

2013-12-11

The PhD thesis develops a stochastic model to explain pricing in Quota Obligation schemes for renewable energy (RE). It is based on the fact that electricity production from RE is depending on weather and other conditions, which leads to a random fluctuation. In the developed model the price for RE is depending on the probability of a lack of certificates at the end of an obligation period. In contrast to deterministic models, the stochastic model has a direct link between the price for RE and their high investment costs. Moreover, the stochastic model can be used to describe the development of prices over an obligation period. The model is adopted to the Swedish quota obligation. It is shown that the real RE prices there are much higher than the estimated prices derived from the model. This result is consistent to the fact that installed RE capacity in Sweden is much higher than necessary to fulfill the quota obligation.

Development of a personal obligation to shift electricity use: Initial determinants and maintenance over time

Energy Technology Data Exchange (ETDEWEB)

Linz, D.; Heberlein, T.

1984-03-01

The present study is an attempt to determine if the beliefs which underly the formation of an obligation to shift electricity use among household consumers also contribute to maintenance of the obligation over time. Utility customer beliefs about and obligation toward shifting electricity use in their households from on-peak to off-peak times were examined in 1977, when the customers had no behavioral experience with electricity shifting. In 1979, after two years of experience with shifting appliance use from on-peak to off-peak times, customers were again surveyed and the same variables measured. The results indicated that the formation of a feeling of obligation to shift electricity in 1977 use was marginally dependent on other beliefs. By 1979, these variables were completely supplanted by the subjects' self-perception of their shifting behavior. While cognitive variables are important in the initial formation of a personal obligation to engage in shifting electricity use, the perpetuation of a feeling of obligation to shift over a period of years depends on perception of how often electricity shifting was undertaken and how much electricity had been shifted from on- to off-peak times.

Certes, il est vrai qu’opérer un rapprochement entre ces deux obligations semble hasardeux, tant leur domaine et leur logique paraissent différents. Pour autant, un tel rapprochement est, non seulement possible, mais vraisemblablement fructueux : possible en premier lieu, car ces deux obligations ont en commun le fait d’entraîner une restriction du pouvoir patronal de direction ; enrichissant également parce que tout porte à croire que l’obligation de reclassement peut - voire doit - s’analyser comme le prolongement de l’obligation de sécurité.In a context marked by increasing concern to protect the health of workers as well as their employment, it is observed that two employers’ obligations—safety and reclassification—play, in French law, a major role in the construction of a right to safety in the workplace and a right to employment.

However, such a connection is not only possible, but probably beneficial : possible first, because these two obligations both involve a restriction of the employers’ management power, and also beneficial because everything leads to the belief that the obligation of reclassification can—and even must—be considered as an extension of the obligation of safety.En un contexto marcado por la constante preocupación de proteger la salud de los trabajadores y su empleo, se observa que dos obligaciones patronales- aquella de seguridad y aquella de reclasificación- desempeñan, en el derecho francés, un papel importante en la construcci

Koneri, Roni; Maabuat, Pience V

The degradation of a habitat will affect the population of butterflies living in it. This study aims to analyse the diversity of butterflies in the area of Manembo-Nembo Wildlife Reserve, North Sulawesi. Employing purposive sampling, the study was conducted for five months. The collection of butterflies was done by using the sweeping technique, following the transect line applied randomly along 1000 m to three types of habitat (the primary forest, riverside in the forest and agricultural land). The species diversity was determined by using diversity index (Shannon-Wiener). The study identified 4 families, 44 species and 748 individual butterflies. Nymphalidae was a family predominantly found (71.12%), while the species mostly found was Ideopsis juventa tontoliensis (10.16%). Abundance (76.50), richness (20.25), diversity (2.66) and species evenness (0.88) were mostly found in riverside habitats in the forest, while the lowest was found in the primary forest. The similarities of butterfly communities in the different types of habitats indicate that the highest similarity index of butterfly communities is in the habitats of the primary forest and riverside in the forest wi a value of 80%. The highest diversity of butterflies in all types of habitats found in riverside. The high diversity of butterflies in the river is strongly influenced by the presence of vegetation as food and host plants of butterflies and this habitat should be conserved for the survival of the butterfly in a wildlife reserve Manembo-Nembo, North Sulawesi. It is expected that the results of this study could become important data of the diversity of butterflies and effects of changes of habitats on the diversity of butterflies in Manembo-Nembo Wildlife Reserve, North Sulawesi.

2014-10-01

Full Text Available Seed dispersal plays a potential role in plant species demographic processes. Elephants are important seed-dispersing agents. We studied frugivory and seed dispersal by Asian Elephants in the tropical deciduous and thorn forests of the Nilgiri Biosphere Reserve, southern India. We determined fruit consumption based on the presence of seeds and fruit remnants in elephant dung piles. In total, we identified seeds of eight plant species belonging to seven families in 16% out of 455 dung piles examined between 1991 and 2004. Coinciding with a peak fruiting season in the study area, seeds and other fruit parts appeared in the dung piles significantly more frequently during the dry season than in the wet seasons (southwest and northeast monsoons. Owing to differences in fruit species abundance in different habitats, there was more evidence of fruit consumption in the dry thorn than in the dry and moist deciduous forests. This corresponds with insufficient grass availability in thorn forests during the dry season and an increase in browse consumption as a supplementary diet. Seeds of Tamarindus indica and Acacia intsia were found in elephant dung more frequently than other species. Seed and fruit remnants were found in almost an equal number of dung piles of both bulls and herds.

The default of the obligation of information, which should only be a deontological fault, had begun to intrude on the area of responsibility, whether it be criminal or indeed civil. 'Ethical' responsibility took over a 'technical' responsibility limited by the primacy of fault. The law of March 4, 2002 prepared the ground for a return of this sword of Damocles towards its natural area, that is to say deontological fault which comes within ordinal jurisdictions. Thus the main contribution of this law is to be found in the definition of medical responsibility which, by limiting responsibility to a technical fault, seems to rule out the default of the obligation of information. The law of March 4, 2002 has not stirred up the content of the obligation of information for all that. The question of the information on exceptional risks is the only one to have noticeably evolved, since information now concerns only predictable risks. Therefore, the law of March 4, 2002, in no way leads to the death of the obligation of information, quite the reverse: the quality requirements in the information of the patient are even reinforced in some of their aspects, but in compensation for these requirements, there is no exacerbated responsibility anymore.

Data from recent conflicts related to war wounds and obligate anaerobes are limited. We define the epidemiology and antimicrobial susceptibility of obligate anaerobes from Iraq and Afghanistan casualties (6/2009-12/2013), as well as their association with clinical outcomes. Susceptibility against eleven antibiotics (7 classes) was tested. Overall, 59 patients had 119 obligate anaerobes identified (83 were first isolates). Obligate anaerobes were isolated 7-13 days post-injury, primarily from lower extremity wounds (43%), and were largely Bacteroides spp. (42%) and Clostridium spp. (19%). Patients with pelvic wounds were more likely to have Bacteroides spp. and concomitant resistant gram-negative aerobes. Seventy-three percent of isolates were resistant to ≥1 antimicrobials. Bacteroides spp. demonstrated the most resistance (16% of first isolates). Patients with resistant isolates had similar outcomes to those with susceptible strains. Serial recovery of isolates occurred in 15% of patients and was significantly associated with isolation of Bacteroides spp., along with resistant gram-negative aerobes. Published by Elsevier Inc.

Ocelot Population Status in Protected Brazilian Atlantic Forest.

Directory of Open Access Journals (Sweden)

Rodrigo Lima Massara

Full Text Available Forest fragmentation and habitat loss are detrimental to top carnivores, such as jaguars (Panthera onca and pumas (Puma concolor, but effects on mesocarnivores, such as ocelots (Leopardus pardalis, are less clear. Ocelots need native forests, but also might benefit from the local extirpation of larger cats such as pumas and jaguars through mesopredator release. We used a standardized camera trap protocol to assess ocelot populations in six protected areas of the Atlantic forest in southeastern Brazil where over 80% of forest remnants are < 50 ha. We tested whether variation in ocelot abundance could be explained by reserve size, forest cover, number of free-ranging domestic dogs and presence of top predators. Ocelot abundance was positively correlated with reserve size and the presence of top predators (jaguar and pumas and negatively correlated with the number of dogs. We also found higher detection probabilities in less forested areas as compared to larger, intact forests. We suspect that smaller home ranges and higher movement rates in smaller, more degraded areas increased detection. Our data do not support the hypothesis of mesopredator release. Rather, our findings indicate that ocelots respond negatively to habitat loss, and thrive in large protected areas inhabited by top predators.

Children's family obligations involve assistance and respect that children are expected to provide to immediate and extended family members and reflect beliefs related to family life that may differ across cultural groups. Mothers, fathers and children (N = 1432 families) in 13 cultural groups in 9 countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand and United States) reported on their expectations regarding children's family obligations and parenting attitudes and behaviours. Within families, mothers and fathers had more concordant expectations regarding children's family obligations than did parents and children. Parenting behaviours that were warmer, less neglectful and more controlling as well as parenting attitudes that were more authoritarian were related to higher expectations regarding children's family obligations between families within cultures as well as between cultures. These international findings advance understanding of children's family obligations by contextualising them both within families and across a number of diverse cultural groups in 9 countries. © 2015 International Union of Psychological Science.

Historically, interstate natural gas pipelines served as aggregators and transporters of gas supplies from the producing fields to the city-gate. In turn, local distribution companies (LDCs) bought gas from pipelines at the city-gate under long-term sales contracts and resold the gas to retail customers. Once a pipeline/LDC sales relationship was established through a regulated certificate process, the LDC was assured of gas supply up to the level of its contract demand (CD) at just and reasonable rates until abandonment of the pipeline's sales service obligation was granted by the Federal Energy Regulatory Commission (FERC). During the years of regulated wellhead pricing and limited gas deliverability, pipelines signed long-term take-or-pay contracts with producers to induce them to develop and commit new gas supplies. Those supply cost obligations were reflected in tariff minimum bill provisions. For years, this pipeline/LDC arrangement was mutually beneficial and provided assured firm service. With the load diversity on large interstate pipeline systems and the make-up provisions under take-or-pay clauses, these gas purchase contracts provided supply reliability without negative economic consequence to the pipelines. Then, with the issuance of FERC Order Nos. 380, 436, and 500, LDCs' obligations to purchase gas from pipeline suppliers according to the terms of those long term sales agreements were irrevocably altered. The impacts of those long term sales agreements were irrevocably altered. The impacts of those orders the elimination of minimum bills and the advent of open access transportation caused a serious erosion of the mutual obligations between pipelines and their LDC customers. The result has been a significant loss of pipeline sales markets as LDC customers have chosen alternative supplied, often at the urging of state public utility commissions (PUCs) to lower short-term costs

Building ties: social capital network analysis of a forest community in a biosphere reserve in Chiapas, Mexico

Directory of Open Access Journals (Sweden)

Luis Rico García-Amado

2012-09-01

Full Text Available Governance of the commons depends on the capacity to generate collective action. Networks and rules that foster that collective action have been defined as social capital. However, their causal link is still not fully understood. We use social network analysis to assess social capital, decision-making, and collective action in a forest-based common pool resource management in La Sepultura Biosphere Reserve (Chiapas, Mexico. Our research analyzes the productive networks and the evolution of coffee groups in one community. The network shows some centrality, with richer landholders tending to occupy core positions and poorer landless peasants occupying peripheral ones. This has fostered the community's environmentally oriented development but has also caused internal conflicts. Market requirements have shaped different but complementary productive networks, where organic coffee commercialization is the main source of bridging ties, which has resulted in more connectivity and resilience. Conservation attitudes, along with the institutional setting of the community, have promoted collective action. The unresolved conflicts, however, still leave some concerns about governance in the future.

Modeling and analysis of renewable energy obligations and technology bandings in the UK electricity market

International Nuclear Information System (INIS)

Gürkan, Gül; Langestraat, Romeo

2014-01-01

In the UK electricity market, generators are obliged to produce part of their electricity with renewable energy resources in accordance with the Renewable Obligation Order. Since 2009 technology banding has been added, meaning that different technologies are rewarded with a different number of certificates. We analyze these two different renewable obligation policies in a mathematical representation of an electricity market with random availabilities of renewable generation outputs and random electricity demand. We also present another, alternative, banding policy. We provide revenue adequate pricing schemes for the three obligation policies. We carry out a simulation study via sampling. A key finding is that the UK banding policy cannot guarantee that the original obligation target is met, hence potentially resulting in more pollution. Our alternative provides a way to make sure that the target is met while supporting less established technologies, but it comes with a significantly higher consumer price. Furthermore, as an undesirable side effect, we observe that a cost reduction in a technology with a high banding (namely offshore wind) leads to more CO 2 emissions under the UK banding policy and to higher consumer prices under the alternative banding policy. - Highlights: • We model and analyze three renewable obligation policies in a mathematical framework. • We provide revenue adequate pricing schemes for the three policies. • We carry out a simulation study via sampling. • The UK policy cannot guarantee that the original obligation target is met. • Cost reductions can lead to more pollution or higher prices under banding policies

UK ignores treaty obligations

Roche, P.

1995-01-01

A detailed critique is offered of United Kingdom (UK) political policy with respect to the Non-Proliferation Treaty, an interim agreement valid while nuclear disarmament was supposed to occur, by a representative of Greenpeace, the anti-nuclear campaigning group. The author argues that the civil and military nuclear programmes are still firmly linked, and emphasises his opinions by quoting examples of how UK politicians have broken treaty obligations in order to pursue their own political, and in some cases financial, goals. It is argued that the treaty has failed to force nuclear countries to disarm because of its promoted civil nuclear power programmes. (U.K.)

Modeling the temporal dynamics of nonstructural carbohydrate pools in forest trees

Energy Technology Data Exchange (ETDEWEB)

Richardson, Andrew [Northern Arizona Univ., Flagstaff, AZ (United States); Harvard Univ., Cambridge, MA (United States)

2017-11-09

Trees store carbohydrates, in the form of sugars and starch, as reserves to be used to power both future growth as well as to support day-to-day metabolic functions. These reserves are particularly important in the context of how trees cope with disturbance and stress—for example, as related to pest outbreaks, wind or ice damage, and extreme climate events. In this project, we measured the size of carbon reserves in forest trees, and determined how quickly these reserves are used and replaced—i.e., their “turnover time”. Our work was conducted at Harvard Forest, a temperate deciduous forest in central Massachusetts. Through field sampling, laboratory-based chemical analyses, and allometric modeling, we scaled these measurements up to whole-tree NSC budgets. We used these data to test and improve computer simulation models of carbon flow through forest ecosystems. Our modeling focused on the mathematical representation of these stored carbon reserves, and we examined the sensitivity of model performance to different model structures. This project contributes to DOE’s goal to improve next-generation models of the earth system, and to understand the impacts of climate change on terrestrial ecosystems.

Tropical savannas and dry forests.

Science.gov (United States)

Pennington, R Toby; Lehmann, Caroline E R; Rowland, Lucy M

2018-05-07

In the tropics, research, conservation and public attention focus on rain forests, but this neglects that half of the global tropics have a seasonally dry climate. These regions are home to dry forests and savannas (Figures 1 and 2), and are the focus of this Primer. The attention given to rain forests is understandable. Their high species diversity, sheer stature and luxuriance thrill biologists today as much as they did the first explorers in the Age of Discovery. Although dry forest and savanna may make less of a first impression, they support a fascinating diversity of plant strategies to cope with stress and disturbance including fire, drought and herbivory. Savannas played a fundamental role in human evolution, and across Africa and India they support iconic megafauna. Copyright © 2018 Elsevier Ltd. All rights reserved.

Soil and water acidification of forest soils in the low-polluted area of Schoenbuch forest reservation

International Nuclear Information System (INIS)

Flegr, M.; Monn, L.

1990-01-01

At a comparatively low atmospheric pollution load of two wood-covered catchment areas the coniferous forest stand is characterized by increased material depositons and large element concentrations in the main root space. This leads to accumulation of acidifying agents and heavy metals in the seepage water. The heavy metals which pass into the recipients with the displaced soil solution determine most of the dispersion of dissolved heavy metals in the plateau landscape. On the other hand, the fraction of heavy metals bound to airborne particulates predominates in the valley landscape because of the stronger relief and the resulting sediment transport. In the shallow groundwaters, the sulfates and nitrate concentrations are much higher than in the deeper ground waters. (orig.) [de

Mid and later life care work migration: Patterns of re-organising informal care obligations in Central and Eastern Europe.

Science.gov (United States)

Bauer, Gudrun; Österle, August

2016-04-01

Many women in mid or later life from Central and Eastern Europe commute for live-in 24-hour care work to Austria. In addition to paid care work abroad, the majority of women in this age group is confronted with informal (family) care obligations towards children, towards older relatives or towards grandchildren. This study aims to explore the patterns of re-organising these informal care obligations (childcare, long-term care and domestic work) in the respective home country and to analyse the factors that determine the re-organisation. The study builds on qualitative interviews with 20 migrant care workers aged 40years and over, 9 Romanian and 11 Slovakian women providing 24-hour care work in Austria. All interviewees commute in 2- to 4-weekly shifts between the home country and Austria and report multiple informal care obligations towards family members in the respective home country. In most cases, members of the nuclear and extended family, and in many cases husbands or partners of migrant care workers, act as the main substitute caregivers. Institutional care provision plays a more important role for child care as against for older people in need of care for whom care services are hardly available or accessible in the countries observed. While re-organisation depends much on the specific family constellations, strong assumptions towards family care, the limitations in (monetary) resources and the lack of public welfare provisions strongly co-determine the arrangements.

Conditions applying to Australian uranium exports - safeguards obligations under NPT

International Nuclear Information System (INIS)

Rotsey, W.B.

1975-08-01

The Australian Government's expressed desire to inhibit the spread of nuclear weapons and its wish to prevent Australia's uranium exports being used for manufacture of nuclear explosives are underwritten by Australia's formal international obligations. Australia is not free to export its material without paying due regard to supra-national requirements. This paper defines two safeguards regimes, one applying to countries such as Australia which are party to the Treaty on Non-Proliferation of Nuclear Weapons (NPT), the other to those which are not parties. The application of safeguards and the role of the International Atomic Energy Agency (IAEA) are briefly explained. Australia's obligations under the NPT and those stemming from specific undertakings to the IAEA are stated. The latter require Australia to ensure that Non-Nuclear Weapons States not party to the NPT give assurances that Australian uranium will not be used for the manufacture of nuclear explosives and that they will permit verification by the IAEA. These obligations give rise to a set of minimum conditions applying to exports of Australian uranium which vary according to the NPT status of the importing countries. (author)

Kant's assessment of motivation in the fulfillment of social obligations.

Science.gov (United States)

Knupp, Jackie

2006-01-01

This paper explores the motivations of physicians who promote the health of their communities through the fulfillment of social obligations beyond the boundaries of their own patients. Based on the assumption that physicians do not have social obligations, this paper looks at the normative, motivational question, namely "How should physicians be motivated to fulfill social obligations?" The paper traces the Kantian view of morality and motivation. The distinctions between required, merely permissible, and forbidden actions is drawn. Furthermore, Kant's view that required actions done in accordance with duty are of no moral worth is critiqued from three stand points. First, it is argued that just because motivations outside of Kantian-based duty are not as good, it does not follow that these motivations are of no moral worth. Second, it is argued that there are some motivations behind required actions that are clearly better than other motivations. Third, it is argued that required actions done in accordance with duty are clearly better than those actions done without relevance to duty. The paper concludes that many required actions done in accordance with duty are performed from motivations that do have moral worth.

Berenty Reserve—A Gallery Forest in Decline in Dry Southern Madagascar—Towards Forest Restoration

Directory of Open Access Journals (Sweden)

Vanessa Winchester

2018-01-01

Full Text Available Berenty Reserve, a fully protected gallery forest beside the Mandrare River is renowned for its lemurs, but the continuous canopy of the main forest is shrinking, fragmenting and degrading. The aim of this study, before any restoration can be considered, is to investigate why canopy-cover is declining and define the forest’s vegetation status and composition. Our study includes analysis of tamarind age (the dominant species and regeneration, forest extent, climate and soil. Measurement of trunk circumference and annual rings indicated a median age of 190 years, near the accepted maximum for tamarinds. There is no regeneration of tamarind seedlings under the canopy and an invasive vine, Cissus quadrangularis suffocates any regeneration on the forest margins. A vegetation survey, based on fifteen transects, broadly characterized three forest areas: continuous canopy near the river, transitional canopy with fewer tall trees, and degraded dryland; the survey also provided a list of the 18 most common tree species. Ring counts of flood-damaged roots combined with measurement to the riverbank show that erosion rates, up to 19.5 cm/year, are not an immediate threat to forest extent. The highly variable climate shows no trend and analysis of forest soil indicates compatibility with plant growth.

Changes in Orchid Bee Communities Across Forest-Agroecosystem Boundaries in Brazilian Atlantic Forest Landscapes.

Science.gov (United States)

De Aguiar, Willian Moura; Sofia, Silvia H; Melo, Gabriel A R; Gaglianone, Maria Cristina

2015-12-01

Deforestation has dramatically reduced the extent of Atlantic Forest cover in Brazil. Orchid bees are key pollinators in neotropical forest, and many species are sensitive to anthropogenic interference. In this sense understanding the matrix permeability for these bees is important for maintaining genetic diversity and pollination services. Our main objective was to assess whether the composition, abundance, and diversity of orchid bees in matrices differed from those in Atlantic forest. To do this we sampled orchid bees at 4-mo intervals from 2007 to 2009 in remnants of Atlantic Forest, and in the surrounding pasture and eucalyptus matrices. The abundance, richness, and diversity of orchid bees diminished significantly from the forest fragment toward the matrix points in the eucalyptus and pasture. Some common or intermediate species in the forest areas, such as Eulaema cingulata (F.) and Euglossa fimbriata Moure, respectively, become rare species in the matrices. Our results show that the orchid bee community is affected by the matrices surrounding the forest fragments. They also suggest that connections between forest fragments need to be improved using friendly matrices that can provide more favorable conditions for bees and increase their dispersal between fragments. © The Authors 2015.

Desiring the city: the urban imaginary in rural collective settlements in a Brazilian submontane Atlantic forest reserve

Directory of Open Access Journals (Sweden)

Bruno César Cavalcanti

Full Text Available This article discusses data obtained in a study on populations who live near an important Brazilian submontane Atlantic forest, a geographical zone of north-eastern states located between the beach zone and the savanna-scrub zone. The populations in question live in a so-called Ecological Station from Murici (Esec-Murici, in the Murici Forest Complex (CFM, in the forest zone of Alagoas, distributed between two Incra rural collective settlements and on farms. Cultural forms used by such populations have been discussed by using social indexes taken from this survey and associating them with economical and environmental sustainability notions in their interfaces with these groups' social development and with regards to the actions of other agents in the CFM, suggesting that the maintenance of an urban imaginary which produces new subjectivities can be easily linked with environmental conservation policies.

Obligation for renewable electricity in the Netherlands. Outline of options and preconditions

International Nuclear Information System (INIS)

Van Tilburg, X.; Jansen, J.C.; Uyterlinde, M.A.; Lensink, S.M.

2006-12-01

In August 2006, the MEP feed-in system was suspended to prevent excess budget claims while the 2010 target is expected to be met. A number of politicians suggest the time is right to change the feed-in system to an obligation scheme. On assignment of the Dutch Ministry of Economic Affairs ECN has reviewed whether The Netherlands could be ready for a successful introduction of an obligation-based support scheme for renewable electricity in the Netherlands. This report is not a detailed study, but offers a survey of possibilities and preconditions. The question whether The Netherlands is ready for a successful introduction can be yes only when two conditions are met. Firstly, the government has to pursue a strategy of long term policy stability, essential for establishing a favourable investment climate. Secondly, a certificate market has to be set up that is able to function properly and efficiently (i.e. sufficient market liquidity). Excessive producers' surplus, under certain circumstances a side effect of an obligation based system, may be reduced using a hybrid approach combining direct subsidies and a quota obligation. This report describes that careful planning is required and hence a possible switch cannot be implemented before 2009 or 2010. The government plays an important role in establishing a.positive and stable investment climate. At the introduction of an obligation based scheme, the government should present an ambitious and broadly supported long term target. Commitment to maintain the obligation for at least fifteen to twenty years ahead is of key importance. In addition to a stable investment climate, it is also important to have a sufficiently transparent and liquid market for tradable green certificates. Whether this is achievable in the Netherlands remains open to investigation. The government has limited means at its disposal for providing sufficient market efficiency. Harmonisation of support schemes at the EU level is not to be expected in

Valorizing the 'Irulas' traditional knowledge of medicinal plants in the Kodiakkarai Reserve Forest, India

Directory of Open Access Journals (Sweden)

Newmaster Steven G

2009-04-01

Full Text Available Abstract A mounting body of critical research is raising the credibility of Traditional Knowledge (TK in scientific studies. These studies have gained credibility because their claims are supported by methods that are repeatable and provide data for quantitative analyses that can be used to assess confidence in the results. The theoretical importance of our study is to test consensus (reliability/replicable of TK within one ancient culture; the Irulas of the Kodiakkarai Reserve Forest (KRF, India. We calculated relative frequency (RF and consensus factor (Fic of TK from 120 Irulas informants knowledgeable of medicinal plants. Our research indicates a high consensus of the Irulas TK concerning medicinal plants. The Irulas revealed a diversity of plants that have medicinal and nutritional utility in their culture and specific ethnotaxa used to treat a variety of illnesses and promote general good health in their communities. Throughout history aboriginal people have been the custodians of bio-diversity and have sustained healthy life-styles in an environmentally sustainable manner. However this knowledge has not been transferred to modern society. We suggest this may be due to the asymmetry between scientific and TK, which demands a new approach that considers the assemblage of TK and scientific knowledge. A greater understanding of TK is beginning to emerge based on our research with both the Irulas and Malasars; they believe that a healthy lifestyle is founded on a healthy environment. These aboriginal groups chose to share this knowledge with society-at-large in order to promote a global lifestyle of health and environmental sustainability.

Leaf litter decomposition is the key ecological process that determines the sustainability of managed forest ecosystems, however very few studies hitherto have investigated this process with respect to silvicultural management practices. The aims of the present study were to investigate the effects of forest management practices on leaf litter decomposition rates, nutrient dynamics (C, N, Mg, K, Ca, P) and the activity of ligninolytic enzymes. We approached these questions using a 473 day long litterbag experiment. We found that age-class beech and spruce forests (high forest management intensity) had significantly higher decomposition rates and nutrient release (most nutrients) than unmanaged deciduous forest reserves (Pforest management (low forest management intensity) exhibited no significant differences in litter decomposition rate, C release, lignin decomposition, and C/N, lignin/N and ligninolytic enzyme patterns compared to the unmanaged deciduous forest reserves, but most nutrient dynamics examined in this study were significantly faster under such near-to-nature forest management practices. Analyzing the activities of ligninolytic enzymes provided evidence that different forest system management practices affect litter decomposition by changing microbial enzyme activities, at least over the investigated time frame of 473 days (laccase, Pforest system management practices can significantly affect important ecological processes and services such as decomposition and nutrient cycling.

The Bali Firewall and Member States’ Future Obligations within the Climate Change Regime

Full Text Available At the 13th Conference of the Parties to the United Nations Framework Convention on Climate Change, held in Bali in 2007, the COP decided to launch a process to reach an agreed outcome at its 15th session held in Copenhagen in 2009. This decision, known as the Bali Action Plan, contains two subparagraphs that set out broadly the parameters within which future possible legal obligations pertaining to developed and developing nations regarding the mitigation of climate change are to be addressed as part of this process as per the decision. The purpose of addressing these obligations is to enable the implementation of the Convention, so the subparagraphs should have a basis in the Convention. One subparagraph deals with future possible legal obligations pertaining to developed country Parties and the other deals with those pertaining to developing country Parties. The content of each subparagraph differs and therefore a fundamental difference in the future possible legal obligations pertaining to developed and developing country Parties is pre-defined within the Bali Action Plan. This difference, as it is perceived by most developing country Parties, has become known colloquially as the Bali firewall. This article will set out the content of the pre-defined sets of parameters and investigate the basis for this content, and difference in content in relation to the other, in the provisions and principles set out in the Convention. It will then conclude on the validity of the Bali firewall in terms of the content of the Convention. Additionally it will analyse whether the ‘outcome’ of the 15th Conference of the Parties falls in line with the future legal obligations of member states within the climate regime as perceived by most developing country Parties in terms of the Bali firewall. Lastly it will analyse member states’ future legal obligations within the climate change regime in the context of the overall objective of the Convention and the

Motivation Counts: Autonomous But Not Obligated Sharing Promotes Happiness in Preschoolers.

Wu, Zhen; Zhang, Zhen; Guo, Rui; Gros-Louis, Julie

Research has demonstrated that prosocial sharing is emotionally rewarding, which leads to further prosocial actions; such a positive feedback loop suggests a proximal mechanism of human's tendency to act prosocially. However, it leaves open a question as to how the emotional benefits from sharing develop in young children and whether sharing under pressure promotes happiness as well. The current study directly compared 3- and 5-year-old Chinese children's happiness when sharing was autonomous (the recipient did not contribute to getting the reward) with when sharing was obligated (the recipient and the actor jointly earned the reward). We found that children shared more items overall when sharing was obligated than autonomous, demonstrating their conformity to social norms of merit-based sharing. In children who eventually shared with others, 5-year-olds gave out more stickers in the obligated sharing condition than in the autonomous sharing condition, but 3-year-olds shared the same amount between the conditions, suggesting that 5-year-olds adhered to the merit-based sharing norm more strictly than 3-year-olds. Moreover, in the autonomous sharing condition, children displayed greater happiness when they shared with the recipient than when they kept stickers for themselves, suggesting that costly prosocial giving benefited children with positive mood; however, children did not gain happiness when they shared with the recipient in the obligated sharing condition. These findings demonstrate that children's affective benefits depend on the motivation underlying their prosocial behavior, and further imply that normative force and emotional gains may independently drive preschoolers' prosocial behaviors.

Full Text Available The objective of this work was to determine the occurrence of birds depending on the use of the area and the content of organic coal in field-and-forest systems. The research demonstrated a great diversity of bird species and great differences in the content of organic coal in individual areas. According to the conducted analyses, human economic activity can influence the content of organic coal and, therefore, it also influences the occurrence of specific bird species. In connection with the fact that the entire area covered with the research has been modelled by humans, the content of organic coal, the composition of bird species and their functioning in spatial systems are derivatives of such an activity.

Protected areas: mixed success in conserving East Africa's evergreen forests.

In East Africa, human population growth and demands for natural resources cause forest loss contributing to increased carbon emissions and reduced biodiversity. Protected Areas (PAs) are intended to conserve habitats and species. Variability in PA effectiveness and 'leakage' (here defined as displacement of deforestation) may lead to different trends in forest loss within, and adjacent to, existing PAs. Here, we quantify spatial variation in trends of evergreen forest coverage in East Africa between 2001 and 2009, and test for correlations with forest accessibility and environmental drivers. We investigate PA effectiveness at local, landscape and national scales, comparing rates of deforestation within park boundaries with those detected in park buffer zones and in unprotected land more generally. Background forest loss (BFL) was estimated at -9.3% (17,167 km(2)), but varied between countries (range: -0.9% to -85.7%; note: no BFL in South Sudan). We document high variability in PA effectiveness within and between PA categories. The most successful PAs were National Parks, although only 26 out of 48 parks increased or maintained their forest area (i.e. Effective parks). Forest Reserves (Ineffective parks, i.e. parks that lose forest from within boundaries: 204 out of 337), Nature Reserves (six out of 12) and Game Parks (24 out of 26) were more likely to lose forest cover. Forest loss in buffer zones around PAs exceeded background forest loss, in some areas indicating leakage driven by Effective National Parks. Human pressure, forest accessibility, protection status, distance to fires and long-term annual rainfall were highly significant drivers of forest loss in East Africa. Some of these factors can be addressed by adjusting park management. However, addressing close links between livelihoods, natural capital and poverty remains a fundamental challenge in East Africa's forest conservation efforts.

The Obligation to Provide Free Basic Education in South Africa: An International Law Perspective

Directory of Open Access Journals (Sweden)

L Arendse

2011-10-01

Full Text Available In South Africa many learners are denied the right to basic education because of the levying of school fees and other educational charges, in spite of the international obligation imposed on government to provide free primary education. This article examines the exact nature and extent of this obligation by exploring the concept of "free" basic education. The applicable international instruments and their interpretation as well as the significance of the right to education as a central, facilitative right are examined in order to establish the content of the right to basic education and the legal obligations that ensue. Against this background, the implications of the South African Constitutional Court's approach to the realisation of socio-economic rights and the possibility of the establishment of a core minimum obligation are analysed. It is argued that learners in South Africa may come from different socio-economic backgrounds but as learners in the same public school domain and as equal bearers of their constitutional right to basic education all of them are entitled to the same type and quality of free basic education.

The impact of a shade coffee certification program on forest conservation: a case study from a wild coffee forest in Ethiopia.

Science.gov (United States)

Takahashi, Ryo; Todo, Yasuyuki

2013-11-30

In recent years, shade coffee certification programs have attracted increasing attention from conservation and development organizations. Certification programs offer an opportunity to link environmental and economic goals by providing a premium price to producers and thereby contributing to forest conservation. However, the significance of the conservation efforts of certification programs remains unclear because of a lack of empirical evidence. The purpose of this study was to examine the impact of a shade coffee certification program on forest conservation. The study was conducted in the Belete-Gera Regional Forest Priority Area in Ethiopia, and remote sensing data of 2005 and 2010 were used to gauge the change of forest area. Using propensity score matching estimation, we found that forests under the coffee certification program were less likely to be deforested than forests without forest coffee. By contrast, the difference in the degree of deforestation between forests with forest coffee but not under the certification program and forests with no forest coffee is statistically insignificant. These results suggest that the certification program has had a large effect on forest protection, decreasing the probability of deforestation by 1.7 percentage points. Copyright © 2013 Elsevier Ltd.

Chu, Hui-Wen; Bushman, Barbara A; Woodard, Rebecca J

2008-01-01

The authors examined relationships among social physique anxiety, obligation to exercise, and exercise choices. College students (N = 337; 200 women, 137 men) volunteered to complete 3 questionnaires: the Social Physique Anxiety Scale (SPAS), Obligatory Exercise Questionnaire (OEQ), and Physical Activity Specification Survey (PASS). On the SPAS, men (M score = 31.9 +/- 8.8) differed from women (M score = 37.3 +/- 8.3; p = .001). Men (M score = 43.0 +/- 9.9) and women (M score = 43.0 +/- 9.6) responded similarly (p = .94) on the OEQ. There was no interaction between sex and exercise level on the SPAS or OEQ. When separated by low, medium, and high SPAS scores, neither OEQ nor exercise scores differed. Obligation to exercise appears to be similar for both sexes. Women, however, appear to have higher levels of anxiety regarding how others evaluate their physique than do men. The combination of level of activity and sex do not appear to be associated with social physique anxiety or obligation to exercise.

Children’s family obligations involve assistance and respect that children are expected to provide to immediate and extended family members and reflect beliefs related to family life that may differ across cultural groups. Mothers, fathers, and children (N = 1,432 families) in 13 cultural groups in nine countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand, and United States) reported on their expectations regarding children’s family obligations and parenting attitudes and behaviors. Within families, mothers and fathers had more concordant expectations regarding children’s family obligations than did parents and children. Parenting behaviors that were warmer, less neglectful, and more controlling as well as parenting attitudes that were more authoritarian were related to higher expectations regarding children’s family obligations between families within cultures as well as between cultures. These international findings advance understanding of children’s family obligations by contextualizing them both within families and across a number of diverse cultural groups in nine countries.

Genetic Information, the Principle of Rescue, and Special Obligations.

Science.gov (United States)

Liao, S Matthew; Mackenzie, Jordan

2018-05-01

In "Genetic Privacy, Disease Prevention, and the Principle of Rescue," Madison Kilbride argues that patients have a duty to warn biological family members about clinically actionable adverse genetic findings. The duty does not stem from the special obligations that we may have to family members, she argues, but rather follows from the principle of rescue, which she understands as the idea that one ought to prevent, reduce, or mitigate the risk of harm to another person when the expected harm is serious and the cost or risk to oneself is sufficiently moderate. We doubt, however, whether the principle of rescue can ground a duty to warn in the cases Kilbride envisages, and we suggest that Kilbride may have underappreciated the role that special obligations could play in generating a duty to warn family members. © 2018 The Hastings Center.

Strategic Petroleum Reserve annual report for calendar year 1998

Energy Technology Data Exchange (ETDEWEB)

NONE

1998-12-31

The Strategic Petroleum Reserve was established in 1975 as an emergency response to the 1973 Arab oil embargo. It is authorized by the Energy Policy and Conservation Act (EPCA), and by the comprehensive energy plans of all Administrations since 1975, in recognition of the long-term dependence of the US on imported crude oil and petroleum products. Section 165 of EPCA requires the Secretary of Energy to submit an Annual Report to the President and the Congress. On May 13, 1998, the Department published a Statement of Administration Policy which reaffirmed its commitment to maintain a Government-owned and controlled, centrally located Strategic Petroleum Reserve of crude oil. The Reserve is to be used solely for responding to the types of severe oil supply interruptions presently contemplated in EPCA. Over the past twenty years, the Reserve has grown as large as 592 million barrels--a peak reached in 1994. From 1994 to 1996, nearly 28 million barrels were sold to raise revenues for the U S Treasury. As of December 31, 1998, the crude oil inventory was 561,108,127 barrels which equated to 60 days of net oil imports during 1998. The US now relies on a combination of both the Reserve and private stocks to meet its oil storage obligations to the International Energy Agency.

Deforestation and forest degradation cause the deterioration of resources and ecosystem services. However, there are still no operational indicators to measure forest status, especially for forest degradation. In the present study, we analysed the thermal response number (TRN, calculated by daily total net radiation divided by daily temperature range) of 163 sites including mature forest, disturbed forest, planted forest, shrubland, grassland, savanna vegetation and cropland. TRN generally increased with latitude, however the regression of TRN against latitude differed among vegetation types. Mature forests are superior as thermal buffers, and had significantly higher TRN than disturbed and planted forests. There was a clear boundary between TRN of forest and non-forest vegetation (i.e. grassland and savanna) with the exception of shrubland, whose TRN overlapped with that of forest vegetation. We propose to use the TRN of local mature forest as the optimal TRN (TRN opt ). A forest with lower than 75% of TRN opt was identified as subjected to significant disturbance, and forests with 66% of TRN opt was the threshold for deforestation within the absolute latitude from 30° to 55°. Our results emphasized the irreplaceable thermal buffer capacity of mature forest. TRN can be used for early warning of deforestation and degradation risk. It is therefore a valuable tool in the effort to protect forests and prevent deforestation. Copyright © 2017 Elsevier B.V. All rights reserved.

Oak Ridge reservation, annual site environmental report summary for 1993

International Nuclear Information System (INIS)

1994-11-01

The U.S. Department of Energy requires annual site environmental reports from facilities that operate under its auspices. To fulfill that requirement, such an annual report is published for the Oak Ridge Reservation, which comprises three major sites, each of which has unique monitoring requirements in addition to many shared obligations. As a result, the report is complex and highly detailed. Annual site environmental reports are public documents that are read by government regulators, scientists, engineers, business people, special interest groups, and members of the public at large. For that reason, the reports need to be accessible to a variety of audiences in addition to being accurate and complete. This pamphlet summarizes environmental activities on the reservation, which for some readers may be adequate; for those who seek more detail, it will lend coherence to their approach to the report itself. The content of this summary was taken from Oak Ridge Reservation Annual Site Environmental Report for 1993. Results of the many environmental monitoring and surveillance activities are detailed in this report

Obligation of information and nuclear medicine after the law of march 4. 2002

International Nuclear Information System (INIS)

Bloch, L.

2002-01-01

The default of the obligation of information, which should only be a deontological fault, had begun to intrude on the area of responsibility, whether it be criminal or indeed civil. 'Ethical' responsibility took over a 'technical' responsibility limited by the primacy of fault. The law of March 4, 2002 prepared the ground for a return of this sword of Damocles towards its natural area, that is to say deontological fault which comes within ordinal jurisdictions. Thus the main contribution of this law is to be found in the definition of medical responsibility which, by limiting responsibility to a technical fault, seems to rule out the default of the obligation of information. The law of March 4, 2002 has not stirred up the content of the obligation of information for all that. The question of the information on exceptional risks is the only one to have noticeably evolved, since information now concerns only predictable risks. Therefore, the law of March 4, 2002, in no way leads to the death of the obligation of information, quite the reverse: the quality requirements in the information of the patient are even reinforced in some of their aspects, but in compensation for these requirements, there is no exacerbated responsibility anymore.

Understanding how commensal obligate anaerobic bacteria regulate immune functions in the large intestine.

Science.gov (United States)

Maier, Eva; Anderson, Rachel C; Roy, Nicole C

2014-12-24

The human gastrointestinal tract is colonised by trillions of commensal bacteria, most of which are obligate anaerobes residing in the large intestine. Appropriate bacterial colonisation is generally known to be critical for human health. In particular, the development and function of the immune system depends on microbial colonisation, and a regulated cross-talk between commensal bacteria, intestinal epithelial cells and immune cells is required to maintain mucosal immune homeostasis. This homeostasis is disturbed in various inflammatory disorders, such as inflammatory bowel diseases. Several in vitro and in vivo studies indicate a role for Faecalibacterium prausnitzii, Bacteroides thetaiotaomicron, Bacteroides fragilis, Akkermansia muciniphila and segmented filamentous bacteria in maintaining intestinal immune homeostasis. These obligate anaerobes are abundant in the healthy intestine but reduced in several inflammatory diseases, suggesting an association with protective effects on human health. However, knowledge of the mechanisms underlying the effects of obligate anaerobic intestinal bacteria remains limited, in part due to the difficulty of co-culturing obligate anaerobes together with oxygen-requiring human epithelial cells. By using novel dual-environment co-culture models, it will be possible to investigate the effects of the unstudied majority of intestinal microorganisms on the human epithelia. This knowledge will provide opportunities for improving human health and reducing the risk of inflammatory diseases.

Do Community-Managed Forests Work? A Biodiversity Perspective

Directory of Open Access Journals (Sweden)

John Terborgh

2017-03-01

Full Text Available Community-managed reserves (CMRs comprise the fastest-growing category of protected areas throughout the tropics. CMRs represent a compromise between advocates of nature conservation and advocates of human development. We ask whether CMRs succeed in achieving the goals of either. A fixed reserve area can produce only a finite resource supply, whereas human populations exploiting them tend to expand rapidly while adopting high-impact technologies to satisfy rising aspirations. Intentions behind the establishment of CMRs may be admirable, but represent an ideal rarely achieved. People tied to the natural forest subsist on income levels that are among the lowest in the Amazon. Limits of sustainable harvesting are often low and rarely known prior to reserve creation or respected thereafter, and resource exhaustion predictably follows. Unintended consequences typically emerge, such as overhunting of the seed dispersers, pollinators, and other animals that provide services essential to perpetuating the forest. CMRs are a low priority for governments, so mostly operate without enforcement, a laxity that encourages illegal forest conversion. Finally, the pull of markets can alter the “business plan” of a reserve overnight, as inhabitants switch to new activities. The reality is that we live in a hyperdynamic world of accelerating change in which past assumptions must continually be re-evaluated.

Forest fires in 2017: a useful lesson

Full Text Available Forest fires in 2017: a useful lesson. Forest fires, together with the decline of silviculture practice, are one of the most important natural disturbances affecting Mediterranean forests. The year 2017 is shaping up to be a record breaking fire season all around Southern Europe and especially in Italy for the sheer amount of hectares burned. Here we discuss about the importance of forest fire management, highlighting the role of prescribed burning and mechanical treatment (e.g., manual removal, thinning in reducing the risk of high-intensity wildfires. We report on the successful applications of those fire management techniques on the pinewoods of Vesuvio National Park and Castel Fusano Natural Reserve. The information compiled in the present article aims to demonstrate the potential relevance and impact of forest resources management for fire hazard reduction and shows the necessity of strong interaction among not only the scientific community, but also forest managers, decision makers and the civic responsibility of society at large.

Czech fiasco with oil reserves has not deterred Slovakia

International Nuclear Information System (INIS)

Haluza, I.

2004-01-01

In order to meet its obligation to keep a 90-day emergency reserve of oil and oil products, Slovakia must purchase about 40% of the required volume of these commodities and complete storage capacity for the reserves. In addition, it must also create a system of storage management for the reserves including a regular exchange of the contents of the tanks. If it does not meet the 2008 deadline, EU structural funds will be decreased. In order to create the missing storage capacity, the Sprava statnych hmotnych rezerv (SSHR - Administration of Public Material Reserves) is considering a solution which Slovnaft, a.s. sees as a major risk for the state. Should the hundreds of millions needed for the building of new tanks not be found in the budget, the state would invite private investors to build the tanks, stated SSHR Chairman, Jan Tusim. Private investors will not endanger public control over the emergency reserves. Other countries also lease tanks. But according to information provided by its chairman, SSHR also wants to make the private investors responsible for the regular exchange of the emergency reserves that must be carried out every four to five years. Given an accurate forecast of price development on international markets, a lot of money can be made on these exchanges. Slovnaft stresses that if the state were no longer responsible for the exchange of the tanks' contents, it would be the state that was at risk not the refineries

Research on the effects of urban sprawl on carbon stocks within urban forests can help support policy for sustainable urban design. This is particularly important given climate change and environmental deterioration as a result of rapid urbanization. The purpose of this study was to quantify the effects of urban sprawl on dynamics of forest carbon stock and density in Xiamen, a typical city experiencing rapid urbanization in China. Forest resource inventory data collected from 32,898 patches in 4 years (1972, 1988, 1996 and 2006), together with remotely sensed data (from 1988, 1996 and 2006), were used to investigate vegetation carbon densities and stocks in Xiamen, China. We classified the forests into four groups: (1) forest patches connected to construction land; (2) forest patches connected to farmland; (3) forest patches connected to both construction land and farmland and (4) close forest patches. Carbon stocks and densities of four different types of forest patches during different urbanization periods in three zones (urban core, suburb and exurb) were compared to assess the impact of human disturbance on forest carbon. In the urban core, the carbon stock and carbon density in all four forest patch types declined over the study period. In the suburbs, different urbanization processes influenced forest carbon density and carbon stock in all four forest patch types. Urban sprawl negatively affected the surrounding forests. In the exurbs, the carbon stock and carbon density in all four forest patch types tended to increase over the study period. The results revealed that human disturbance played the dominant role in influencing the carbon stock and density of forest patches close to the locations of human activities. In forest patches far away from the locations of human activities, natural forest regrowth was the dominant factor affecting carbon stock and density. Copyright © 2012 Elsevier Ltd.

Kang, Dongwei; Wang, Xiaorong; Li, Shuang; Li, Junqing

2017-06-15

Artificial restoration is an important way to restore forests, but little is known about its effect on the habitat restoration of the giant panda. In the present study, we investigated the characteristics of artificial forest in the Wanglang Nature Reserve to determine whether through succession it has formed a suitable habitat for the giant panda. We compared artificial forest characteristics with those of natural habitat used by the giant panda. We found that the dominant tree species in artificial forest differed from those in the natural habitat. The artificial forest had lower plant species richness and diversity in the tree and shrub layers than did the latter, and its community structure was characterized by smaller tree and bamboo sizes, and fewer and lower bamboo clumps, but more trees and larger shrub sizes. The typical community collocation of artificial forest was a "Picea asperata + no-bamboo" model, which differs starkly from the giant panda's natural habitat. After several years of restoration, the artificial forest has failed to become a suitable habitat for the giant panda. Therefore, a simple way of planting individual trees cannot restore giant panda habitat; instead, habitat restoration should be based on the habitat requirements of the giant panda.

Bird data have been collected through surveys, environmental assessments, and other observations for decades in the Oak Ridge National Environmental Research Park, located on the US Department of Energy’s Oak Ridge Reservation (ORR) in East Tennessee. Birds were recorded in a variety of habitats, including wetlands, interior forests, grasslands, ponds, corridors, forest edges, and more. Most of the information was gathered from waterfowl surveys conducted from 1990 to 2008, from Partners in Flight (PIF) breeding bird surveys conducted from 1995 to 2013, and from past publications and research on Reservation birds. We have also included our own observations and, in a few instances, credible observations of ORR birds of which we have been made aware through eBird or discussions with area ornithologists and bird watchers. For the period 1950-2014, we were able to document 228 species of birds on the ORR. Several of these species are known from historic records only, while others were not known to have ever occurred on the Reservation until recently. This report does not include PIF breeding bird data from the 2014 season or any records after July 2014. Twenty-two species--approximately 10% of the total number of species observed--have state-listed status in Tennessee as endangered, threatened, or in need of management. Of the 228 species we documented, 120 are believed to be breeding birds on the ORR.

2012-11-01

Full Text Available In a study of the metazoan community composition in tree hole aquatic habitat of a tropical rainforest, Silent Valley National Park, and the adjacent moist deciduous forest, New Amarambalam Reserve Forest, of the Western Ghats, 28 different species were recorded from 150 tree hole aquatic habitats with an average of 3-5 species per tree hole. Most of the recorded organisms (96.8% belong to Odonata (dragonflies and damselflies, Heteroptera (bugs, Diptera (flies, Coleoptera (beetles and Trichoptera (caddisflies. The study reports the first record of toe-winged beetle larvae (Ptilodactylidae in a tree hole aquatic habitat. The most significant observation is the prolific occurrence of trichopteran larvae as the second most abundant taxa in tree holes of Silent Valley National Park, and this stands as the first comprehensive record of the entire order in the habitat studied. The study upholds the importance of less explored microhabitats in the Western Ghats region in terms of sustaining unique community composition in the most delicate and extreme habitat conditions. It also puts forward important ecological research questions on biodiversity ecosystem functionality which could impart important lessons for managing and conserving the diminishing tropical evergreen forests which are significant for these unique habitats.

Evidence is presented of the current threats to the Maya Biosphere Reserve in northern Guatemala as derived through time-series Landsat Thematic Mapper observations and analysis. Estimates of deforestation rates and trends are examined for different management units within the reserve and buffer zones. The satellite imagery was used to quantify and monitor rates, patterns, and trends of forest clearing during a time period corresponding to new road construction and significant human migration into the newly accessible forest region. Satellite imagery is appropriate technology in a vast and remote tropical region where aerial photography and extensive field-based methods are not cost-effective and current, timely data is essential for establishing conservation priorities.

Urban forest is one of the positive factors that increase urban carbon sequestration, which makes great contribution to the global carbon cycle. Based on the high spatial resolution imagery of QuickBird in the study area within the ring road in Yiwu, Zhejiang, the forests in the area were divided into four types, i. e., park-forest, shelter-forest, company-forest and others. With the carbon stock from sample plot as dependent variable, at the significance level of 0.01, the stepwise linear regression method was used to select independent variables from 50 factors such as band grayscale values, vegetation index, texture information and so on. Finally, the remote sensing based forest carbon stock estimation models for the four types of forest were established. The estimation accuracies for all the models were around 70%, with the total carbon reserve of each forest type in the area being estimated as 3623. 80, 5245.78, 5284.84, 5343.65 t, respectively. From the carbon density map, it was found that the carbon reserves were mainly in the range of 25-35 t · hm(-2). In the future, urban forest planners could further improve the ability of forest carbon sequestration through afforestation and interplanting of trees and low shrubs.

2009-07-01

According to EU's Climate and Energy Plan Finland is obliged to increase the proportion of renewable energy sources considerably by the year 2020. The obligation is challenging and requires among others a considerably increased use of biomass. Besides wood energy crop production provides a considerable potential as energy source in Finland. Farmer forest owners are one of the key groups regarding the supply of field energy crops and energy wood in Finland. Basically, farmers have a positive attitude towards the production of field energy crops and energy wood. Their interest in bio-energy related entrepreneurship has also increased in recent years. However, farmers do not find the business environment of biomass production satisfactory. Still the results indicate that the number of field crop producers would at least double by the year 2012. The increase is, however, considerably less than the estimated potential of recent scenarios. The results also imply that famer forest owners have not any intentions to increase their energy wood supplies in the next few years. This is mainly due to undeveloped energy wood markets and unsatisfactory energy wood prices. In order to enhance the biomass production and supply, both field energy crop and energy wood markets and extension need to be improved to meet farmers' needs. (orig.)

Protected Areas: Mixed Success in Conserving East Africa’s Evergreen Forests

Science.gov (United States)

Pfeifer, Marion; Burgess, Neil D.; Swetnam, Ruth D.; Platts, Philip J.; Willcock, Simon; Marchant, Robert

2012-01-01

In East Africa, human population growth and demands for natural resources cause forest loss contributing to increased carbon emissions and reduced biodiversity. Protected Areas (PAs) are intended to conserve habitats and species. Variability in PA effectiveness and ‘leakage’ (here defined as displacement of deforestation) may lead to different trends in forest loss within, and adjacent to, existing PAs. Here, we quantify spatial variation in trends of evergreen forest coverage in East Africa between 2001 and 2009, and test for correlations with forest accessibility and environmental drivers. We investigate PA effectiveness at local, landscape and national scales, comparing rates of deforestation within park boundaries with those detected in park buffer zones and in unprotected land more generally. Background forest loss (BFL) was estimated at −9.3% (17,167 km2), but varied between countries (range: −0.9% to −85.7%; note: no BFL in South Sudan). We document high variability in PA effectiveness within and between PA categories. The most successful PAs were National Parks, although only 26 out of 48 parks increased or maintained their forest area (i.e. Effective parks). Forest Reserves (Ineffective parks, i.e. parks that lose forest from within boundaries: 204 out of 337), Nature Reserves (six out of 12) and Game Parks (24 out of 26) were more likely to lose forest cover. Forest loss in buffer zones around PAs exceeded background forest loss, in some areas indicating leakage driven by Effective National Parks. Human pressure, forest accessibility, protection status, distance to fires and long-term annual rainfall were highly significant drivers of forest loss in East Africa. Some of these factors can be addressed by adjusting park management. However, addressing close links between livelihoods, natural capital and poverty remains a fundamental challenge in East Africa’s forest conservation efforts. PMID:22768074

Obligations, internalization, and excuse making: integrating the triangle model and self-determination theory.

Science.gov (United States)

Sheldon, Kennon M; Schachtman, Todd R

2007-04-01

Schlenker's triangle model (Schlenker, Britt, Pennington, Murphy, & Doherty, 1994, Schlenker, Pontari, & Christopher, 2001) identifies three excuses people use to avoid taking responsibility after failure: that one had no control in the situation, that the obligation was unclear, and that it was not really one's obligation. Three retrospective studies tested the presumed negative association between excuse making and responsibility taking. The studies also examined the effects of self-determination theory's concept of motivational internalization (Deci & Ryan, 2000) upon these variables. A complex but replicable pattern emerged, such that responsibility taking and motivational internalization correlated with adaptive outcomes such as future commitment and positive expectancy and excuse making did not. Of particular interest, perceiving that the person levying the obligation internalized motivation predicted responsibility taking, in all three studies. Implications for the triangle model, as well as for theories of maturity and personality development, are considered.

Consequence in Law of the Original Contract Obligation in Case of Recovery of Losses Incurred by Nonfulfillment or Improper Fulfillment of the Contract

Directory of Open Access Journals (Sweden)

Popov I. V.

2012-11-01

Full Text Available The issue of the obligations structure concerning the breach of a contract is considered in the article. According to the author’s opinion there simultaneously exists the initial obligation in conformity with the contract and obligation of losses compensation for the contract breach. Such an approach allows to recover damages before the moment when the initial obligation is discontinued by law or by a contract provision. The correlation between the initial obligation and the obligation to compensate losses because of the contract breach is being analyzed here.

Mangrove crabs as key ecosystem engineers may play an important role in the recovery process of storm-damaged forests. Yet, their response to storm disturbance is largely unknown. Here we compare the ground-dwelling brachyuran crab community of intact mangrove stands with that of typhoon gaps having experienced 100% tree mortality. Field work was conducted in two adjacent areas in Can Gio Biosphere Reserve, southern Vietnam. In each area, an 18-20 yr old monoculture Rhizophora apiculata stand served as control and was compared with typhoon gaps where downed stems had been removed or left on-site. The gaps were 14 and 20 months old when studied in the dry and rainy season 2008, respectively. Time-based sampling of ground-dwelling crabs with hand or shovel was conducted by 4 persons inside 100 m2 plots for 30 min (7 replicate plots per area, treatment and month). Abiotic (sediment pH, salinity, temperature, grain size, water content, carbon and nitrogen content), and biotic measures (e.g. canopy coverage, woody debris, number of trees, leaf litter) were also taken. Despite complete canopy loss, total crab abundance has not changed significantly (in contrast to biomass) and all 12 species found in the forest were also found in the gaps, demonstrating their robustness. Another 9 gap-exclusive species were recorded and average species number and Shannon diversity were thus higher in the gaps. Perisesarma eumolpe was the most abundant species, both in the forest and in the gaps, and a shift from sesarmids (typical forest species) to ocypodids (generally more prominent in open areas) has not occurred. The persistence of litter-feeding sesarmid crabs prior to the re-establishment of a mangrove canopy is likely to depend on the availability of woody debris on the ground of the gaps, fuelling a mangrove detritus based food web, rather than one based on microphytobenthos and deposit-feeding ocypodids. The presence of burrowing crabs in the gaps suggests that important

Trybou, Jeroen; Gemmel, Paul

2016-07-01

The aim of the study was to examine the relationship between the perceived quality of organisational exchange and nurses' customer-oriented behaviours. Hospitals face increasing competitive market conditions. Registered nurses interact closely with patients and therefore play an important front-office role towards patients. A cross-sectional study was conducted. Registered nurses (n = 151) of a Belgian hospital received a questionnaire to assess the fulfilment of administrative and professional organisational obligations and their customer-oriented behaviours. We found a positive relationship between psychological contract fulfilment and nurses' customer-oriented behaviours. More precisely administrative and professional psychological contract fulfilment relates significantly to nurses' service delivery and external representation. In case of internal influence only administrative psychological contract fulfilment was significantly related. Nurses' perceptions of the fulfilment of administrative and professional obligations are important to their customer-oriented behaviours. Nurse managers must be aware of the impact of fulfilling both administrative and professional obligations of registered nurses in order to optimise their customer-oriented behaviours. © 2016 John Wiley & Sons Ltd.

Transfer of financial obligations for the disposal of nuclear waste and decommissioning of German NPP's. Legal aspects of a trust model

International Nuclear Information System (INIS)

Schewe, Markus; Wiesendahl, Stefan

2015-01-01

The nuclear power plant operators have to bear the costs associated with the closure and the decommissioning of the German nuclear power plants as well as the costs for the disposal of nuclear waste. For that purpose, the operators have to build up sufficient reserves for the decommissioning phase. These reserves at the end of 2013 amounted to approximately 36 billion Euro. Changing this system is discussed very so often. Last in May 2014, a public debate started dealing with the so called trust model (''Stiftungsmodell''). The press published deliberations of several operators to transfer their entire nuclear business to the Federal Republic of Germany. Under this deliberation the current nuclear power plant operations, as well as closure obligations would be contributed to trust. Further, also the reserves should be ''transferred'' to the trust. RAG-Foundation (RAG-Stiftung) - which will assume the financial obligations in connection with Germany's closure of underground coal mining activities - sometimes is cited as a role model. The article covers elements of German trust law and atomic energy law regarding such deliberations. In trust law e.g. it can be debated whether the trust should be established under public or - as in the case of RAG-Foundation - under private law. In this context we will set out the major differences between those two options. In the public law part we will notably address issues arising from individual licensing requirements for nuclear power plants and focus on questions concerning reliability, requisite qualification and organizational structures.

An ethnobotanical study of medicinal plants was carried out in 14 villages adjacent to Mabira Central Forest Reserve (CFR) in Central Uganda between August 2013 and March 2014. Information was obtained through interviews using semi- structured questionnaires. Field excursions with traditional healers and herbal medicine collectors were carried out. Descriptive statistics were used to present the data. Fidelity ratios and Informant consensus agreements were calculated. A total of 190 plant species in 61 families and 152 genera were reported in the treatment of various health conditions. Family Fabaceae was dominant representing 14 % of the plant species documented. Vernonia amygdalina was the preferred species for treating malaria. Leaves (68 %) were the most frequently used parts in preparing herbal remedies. Decoctions (29 %) and oral route (53 %) of administration were commonly used method of herbal medicine preparation and administration respectively. Fifty-eight health conditions grouped in 25 categories were treated using medicinal plants. Informant consensus agreement was highest for blood system disorders (0.9) that included anaemia, hypertension and blood cleansing indicating homogeneity of informant's knowledge about remedies used. Vernonia amygdalina and Erythrina abyssinica had 100 % fidelity level for treatment of malaria and vomiting respectively. The diversity of medicinal plant species used and the associated indigenous knowledge are of great value to the local community and their conservation and preservation is paramount. The therapeutic uses of the documented plants provides basic data for further research focused on pharmacological studies and conservation of the most important species.

Nepal has successfully established more than 370,000 ha of plantations, mostly with Pinus patula, in the last three and a half decades. However, intensive management of these planted forests is very limited. Despite the fact that the Kyoto Convention in 1997 recognized the role of plantations for forest-carbon sequestration, there is still limited knowledge on the effects of management practices and stand density on carbon-sequestration of popular plantation species (i.e. Pinus patula) in Nepal. We carried out case studies in four community forests planted between 1976 and 1990 to assess the impacts of management on forest carbon stocks. The study found that the average carbon stock in the pine plantations was 217 Mg C ha -1 , and was lower in forests with intensively managed plantations (214.3 Mg C ha -1 ) than in traditionally managed plantations (219 Mg C ha -1 ). However, it was the reverse in case of soil carbon, which was higher (78.65 Mg C ha -1 ) in the forests with intensive management. Though stand density was positively correlated with carbon stock, the proportionate increment in carbon stock was lower with increasing stand density, as carbon stock increased by less than 25% with a doubling of stand density (300-600). The total carbon stock was higher in plantations aged between 25 and 30 years compared to those aged between 30 and 35 years. Copyright © 2017 Elsevier Ltd. All rights reserved.

Full Text Available This paper deals with public service obligation, a form of state aid that applies to air services. The paper first provides general information on the European legislation applying to this form of state aid, and elaborates the legal framework and general principles. The second part is dedicated to a comparison of a similar subsidizing programme in the USA and Australia. An examination of current imposed public service obligation routes in Europe is provided in the following section. The coefficients defining the number of imposed PSO routes per various geo-economic variables have been defined.

Woodland reserves within an urban agglomeration as important refuges for small mammals

Full Text Available The aim of the study was to determine the species richness (S, Chao- 1 index and diversity (Shannon-Wiener H’ index, diversity profiles of small mammal assemblages in woodland reserves in an urban agglomeration and to compare the similarity of assemblages (with the use of Ward’s method in terms of proportions of small mammals connected to the habitats of different level of naturalness. The work was conducted from 2004-2015 at 9 woodland reserves in Warsaw (Poland. On the basis of the analysis of pellets of tawny owls Strix aluco, 2792 individuals were identified (24 species. Reserves supported from 7 to 16 of the small mammal species, the highest overall number of species estimated (Chao-1 was 19. Species present in every reserve were Apodemus flavicollis, A. agrarius, Rattus norvegicus, Sorex araneus and Talpa europaea. Least frequent were Microtus agrestis and M. subterraneus. Seven species of bats were detected. Species diversity was lower in the biggest forest complexes, where forest rodents dominated small mammal assemblage. The heterogeneity of habitats within reserve and in the surroundings, in combination with limited human-interference, resulted in an increase in the species diversity. Overall, the reserves under study were an important refuge for small mammals within the Warsaw agglomeration. However, safeguarding of adjacent areas against excessive anthropogenic change is needed and ecological corridors that link different areas need to be retained.
