Mangroves of Sundarbans are rich in biodiversity and under constant threat of exposure of diverse xenobiotics including arsenic. Mudcrab, a resident of this estuary is an edible species of economical importance. Exposure of arsenic resulted in physiological adversities like hemocyte dysfunction an undesirable shift of innate immunity and cytotoxic response in mudcrab. Natural and accidental wounding of tissue and organ are not uncommon in the hostile environment of mangrove. Arsenic induced alteration of kinetics of wound healing and behavioural shift render a possible reduction of ecological fitness of mudcrab. Undesirable change in immunological status and behaviour may lead to decline in population of mudcrab in its natural habitat. Thus, arsenic is apprehended as a causative factor for loss of this important bioresource of indian estuary. ····· 10361115800

Both temporal and spatial variation have been recorded in the different diversity profile of aquatic insects indicating considerable interference by human society and natural conditions. Different orders of insects being integral members of lentic water bodies have also caused surprising variation in their species richness, abundance, evenness and dominance.This has given rise to portfolio effect of the species distribution in which the individuals variation is greater as compare to community variation which is lowest and vice versa. Varying numerical data of diversity information statistics supportive of correlated heterogeneous population dynamics of aquatic insects achieved though this investigation proved as mathematical server for mapping the species diversity status of aquatic insects in this water bodies. Nevertheless species diversity maps both at community level Subject to unpredictable variation because of the fact that the quantum of individual diversity is inversely related to that of community population. ····· 10361115789

The Ganges River dolphin (Platanista gangetica gangetica),locally known as Susu, is restricted to the Ganga, Brahamputra, Karnaphuli-Sangu and Meghna river systems and their tributaries. Once believed to be in tens of thousands, their numbers have gradually reduced to 1800-2000 individuals in all the tributaries of its distribution. The subspecies is facing a series of threats to its survival including poaching,habitat destruction and incidental catches in gill nets. Information on the effects of anthropogenic pressure on dolphin distribution is either scanty or completely lacking, and thus are an impediment to effectively understand the conservation needs of the species. ····· 10361115703

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Deforestation rate in Ethiopia is estimated to be 150,000 to 200,000 ha/annum. Because of this a considerable area of what was once a closed forest had been converted to a heavily disturbed forest. The chief reasons for reduction of the forest are uncontrolled exploitation, forest fires and the expansion of permanently cultivated areas. In order to maintain the ecological equilibrium and to meet the forest resources requirement of the population, scientific information is the basis. The Dodola forest is one of the few remaining dry Afromontane coniferous forests Ethiopia. It is dominated by Juniperus procera, Podocarpus falcatus and Maytenus addat at altitudes below 2800 m. Areas above 3200 m are dominated by Erica arborea. Juniperus procera is the most dominant species in the forest. Phytogeographically this forest is more related to the dry Afromontane forests of the central plateau of Shewa than to the moist Afromontane forests of Harenna and South West Ethiopia. This analysis may serve as a basis for foresters, plant ecologists as a reference material and for the forest managers as an input indevising the management plan of the forest. ····· 10361115417

The country had just discovered that the tiger had become locally extinct from a premier Protected Area. The large public and media coverage led to formation of a Tiger Task Force, which pointed out that India`s tiger conservation schemes had been lacking in collecting support from local communities. If a conservation scheme antagonizes local people, there is very little chance for success. With this background, we set out to test the utility of a new methodology. Conservation needed methods that could be employed on ground without having to wait for large scale policy change. And our method provides us that opportunity. Through this publication, we hope to bring the scientific community a little closer to answering pertinent questions about balancing stakeholder aspirations, natural justice, and prudence of environmental management. We hope that this work will contribute to societal discourse on incorporating local expectations in management of sensitive ecosystems, and would be useful to Protected Area managers, academicians and NGOs and all those working on natural resources management. ····· 10361115354

The current study was undertaken to understand the change process in peri-urban and rural landscapes and analyzed the various driving forces that are leading such changes in land use and land cover. The theoretical approach developed here is based on standard driving forces which influence the farmer`s decision and behaviour. The main driving forces which influence farmers` decision are environmental resources, socio-economic resources, policies and national economy. These are widely accepted from a global to a local scale. Yet, knowledge on changes in the spatial patterns of agricultural land use, the driving factors behind these changes, and their implications within the context of sustainable development is limited in rural and peri-urban landscapes. ····· 10361115312

It is imperative to understand the ecological process of mixed-species stands for developing management decision-making tools. Few models or modeling strategies have been developed and evaluated for mixed-species stands. The first part of this book develops a principal component and cluster analysis procedure to group tree species for ecological and growth modeling. Using stem-mapped data, the second part characterizes tree spatial distributions and develops individual-based spatially explicit growth and survival models to quantify neighborhood effects in a natural temperate species-rich forest. The last part develops a multi-species density-dependent matrix growth model and individual-tree distance-independent growth and mortality models for the bottomland mixed-species hardwoods in the Lower Mississippi Alluvial Valley. The modeling strategies can help forest ecologists and managers better understand the ecological processes of mixed-species stands and develop management regimes for such stands. ····· 10361114960

A twig- galling cynipid wasp and a fungal canker were associated with crown dieback. Symptoms were more severe in residential and urban park `ecotypes` than forested areas. Residual gall wasp populations from within twigs were compared among ecotypes and three crown categories (low, moderate and severe dieback). Insect populations were significantly greater on trees with severe crown dieback in residential areas and urban parks. In forested areas, insect numbers were similar among crown categories. Radial growth differed significantly between trees with severe and low crown dieback prior to 1980 in one residential area, one forested area and both urban parks. High numbers of gall wasps associated with urban areas, combined with previous stressors, are likely to have contributed to the greater severity of decline in parks and residential areas than forested areas. ····· 10361114724

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Kayas are isolated forested patches of land currently used as cultural sites by Mijikendas. Research in early 1990s, identified the Kayas as very important sites for biodiversity conservation because they hosted endemic and globally threatened species. Extraction of forest products in the Kayas was controlled by a Mijikenda council of elders through issuance of permits to locals. This system of traditional governance worked effectively in the past and ensured minimal destruction of Kaya forest habitat, because the Mijikendas strictly obeyed their cultural traditions. However, as human population increased around these sites, the demand for resources increased and the locals started disregarding their traditions and illegally extracting forest products without seeking permission from the council of elders. In recent time this has led to uncontrolled exploitation of forests products leading to decline in populations of globally threatened birds and other biodiversity. This trend is still continuing and is affecting Kayas listed in the World Heritage List from Kenya such as Kaya Gandini & Kaya Mtswakara. There is an urgent need to reverse the trend in the destruction of these Kayas. ····· 10361114553

In support of the isolation by distance model of Wright (1943) simulations shows that under restricted gene flow and selective neutrality, the population as a whole develops a patchy distribution of genotypes. In this study 3 populations of Picrorhiza kurrooa were sampled from habitats that may have different historical geologic processes. The region under study is a physiographically complex mountainous territory, so it represents an excellent model system to study the effect of mountain ranges as barriers to interpopulational gene flow. One population was located in the greater Himalayas (Ladakh range) and lies to the north of the main Himalaya the other 2 populations were collected from middle Himalayans (Sonamarg and Gurez) to the south of the Himalayan terrain. Spatial analysis of population genetic structure by RAPD provides relevant molecular genetic information about fragmentation patterns and landscape genetics that shape population genetic structure and adaptive genetic variation in natural populations of Picrorhiza kurrooa. ····· 10361114320
