Daytime resting mosquito densities in 4 habitat types (wooded, residential yard, garden, and crop) were examined to determine if areas other than wooded ones may be serving as prime mosquito resting habitat. Adult Aedes vexans were collected in the Minneapolis-St. Paul metropolitan area with large battery-powered aspirators to determine mosquito densities at randomly chosen sites within the met...

The rapid spread and diversification of outdoor recreation can impact on wildlife in various ways, often leading to the avoidance of disturbed habitats. To mitigate human-wildlife conflicts, spatial zonation schemes can be implemented to separate human activities from key wildlife habitats, e.g., by designating undisturbed wildlife refuges or areas with some level of restriction to human recrea...

Glossary Cover type A term used by the geographers for a type of mapped feature (e.g., forest, freshwater, or grassland). The dominant natural cover type in a landscape is often used to approximate habitat. Fragmentation per se The breaking apart of habitat while keeping habitat amount constant. Habitat The place where an organism normally lives. Habitat fragmentation The breaking apart of habi...

Background. Understanding species distribution, especially areas of overlapping habitat between sympatric species, is essential for informing conservation through natural habitat protection. New protection strategies should simultaneously consider conservation efforts for multiple species that exist within the same landscape, which requires studies that include habitat overlap analysis. Methods...

—Habitat fragmentation is a significant threat to biodiversity worldwide. Habitat loss and the isolation of habitat fragments disrupt biological communities, accelerate the extinction of populations, and often lead to the alteration of behavioral patterns typical of individuals in large, contiguous natural areas. We used radio-telemetry to study the space-use behavior of the Coachwhip, a larger...

Energy extraction within forest habitat is increasing at a rapid rate throughout eastern North America from the combined presence of conventional oil and gas, shale gas, and wind energy. We examined the effects of conventional oil and gas development on forest habitat including amounts of core and edge forest, the abundance of songbird species and guilds, species diversity, and community simila...

BACKGROUND Habitat fragmentation, water resources and biological characteristics are important factors that shape the genetic structure and geographical distribution of desert plants. Analysis of the relationships between these factors and population genetic variation should help to determine the evolutionary potential and conservation strategies for genetic resources for desert plant populatio...

The future of biodiversity hinges to a great extent on the conservation value of countryside, the growing fraction of Earth's surface heavily influenced by human activities. How many species, and which species, can persist in such landscapes (and analogous seascapes) are open questions. Here we explore two complementary theoretical frameworks to address these questions: species-area relationshi...

A reliable species–area relationship holds true for a number of terrestrial systems. When species–area data are plotted on logarithmic axes, the slope bears strong consistency across taxa. This study examined effects of habitat space on the diversity of coral reef fish species. Because habitat space on coral reefs is 3-dimensional, we developed and employed a methodology that accounts for volum...
