Exotic plant species invade hot spots of native plant diversity

Some theories and experimental studies suggest that areas of low plant species richness may be invaded more easily than areas of high plant species richness. We gathered nested-scale vegetation data on plant species richness, foliar cover, and frequency from 200 1-m2 subplots (20 1000-m2 modified-Whittaker plots) in the Colorado Rockies (USA), and...

A female black bear denning habitat model using a geographic information system

We used the Mahalanobis distance statistic and a raster geographic information system (GIS) to model potential black bear (Ursus americanus) denning habitat in the Ouachita Mountains of Arkansas. The Mahalanobis distance statistic was used to represent the standard squared distance between sample variates in the GIS database (forest cover type,...

Imperiled mammalian fauna of aquatic ecosystems in the Southeast: A historical perspective: Chapter 9

About 100 species of mammals are endemic to the southeastern United States, an area of diverse habitat types and high biodiversity. Many of these species are either formally considered aquatic or semi-aquatic, or they are otherwise closely associated with aquatic ecosystems. In the southeastern United States, greater than 80 percent of mammalian...
