Kenya over the last few decades, and the change from a nomadic lifestyle to communally owned ranches, wildlife in the Samburu District is under threat from deforestation, land degradation, overgrazing by livestock, and unsustainable water use. Alexander Njue, who is also involved in a separate Earthwatchsponsored project studying the wildlife habitats in this area, hopes that wildlife can also ...

An understanding of the habitat selection patterns by wild herbivores is critical for adaptive management, particularly towards ecosystem management and wildlife conservation in semi arid savanna ecosystems. We tested the following predictions: (i) surface water availability, habitat quality and human presence have a strong influence on the spatial distribution of wild herbivores in the dry sea...

Land-use change is a major cause of wildlife habitat loss. Understanding how changes in land-use policies and economic factors can impact future trends in land use and wildlife habitat loss is therefore critical for conservation efforts. Our goal here was to evaluate the consequences of future land-use changes under different conservation policies and crop market conditions on habitat loss for ...

Introduction Utah’s wetlands provide a constellation of recreational opportunities, from sailing to photography, fishing to birdand wildlife-watching, hunting to picnicking. Even more important are the roles wetlands play in the functioning of Utah’s ecosystems. These roles include flood control, maintenance of groundwater quality and levels, pollution control, water purification, and the provi...

Today, modeling is critical for cognition and analysis of designers in industry field to meet their needs and design based on design requirements and available facilities to accelerate production and development of components of industrial engines. In this study, one structure has been proposed, designed, and analyzed based on turboshaft marine engine type to test this kind of engine in order t...

Reintroducing fire to manage vegetation and fuel may have poorly understood consequences for wildlife. Prescribed burning can reduce down wood and snags that provide critical habitat and mechanical thinning designed to reduce fire hazards may alter forest structures that are preferred by some species. Moreover, fine scale fuel treatments may alter wildlife and habitat dynamics within the larger...

Managers of large river basins face conflicting demands for water resources such as wildlife habitat, water supply, wastewater assimilative capacity, flood control, hydroelectricity, and recreation. The Savannah River Basin, for example, has experienced three major droughts since 2000 that resulted in record low water levels in its reservoirs, impacting dependent economies for years. The Savann...
