We tested the hypothesis that recent (between 1990 and 2000) population increases may result in increased threats to biodiversity. GIS data were compiled from the International Union for the Conservation of Nature, BirdLife, and the Socioeconomic Data and Applications Center. Polygon data sets were transformed into rasters with different resolutions from 2.5 to 1 . Relationships between species diversity were assessed globally and separately for terrestrial vertebrates (mammals, birds, reptiles, and amphibians) and for five countries (Cambodia, Laos, Myanmar, Thailand, and Vietnam). The number of species within a 20 km -cell varied greatly and reached a maximum of 801. The species-rich cells (> 700 species) were located in a single, almost continuous area across Myanmar, Thai- land, Vietnam, and South China. The relationship between vertebrate biodiversity and pop- −2 ulation density showed that biodiversity increased with HPD http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Biodiversity and Conservation Springer Journals
