Effect of Species Rarity on the Accuracy of Species Distribution Models
Species distribution models are widely used, at multiple scales, to predict the geographical distribution of habitat suitability or species occurrence. Several studies have found that more accurate predictive models of species occurrences can be developed for rarer species.
Many places on Earth harbor life, but the conditions that shape these environments—weather, climate, and even the organisms themselves—are widely varying, resulting in the amazingly diverse landscape of the Nation that includes caves, forests, coastlines, and deserts. The Status and Trends of Biological Resources Program studies the diverse terrestrial and aquatic ecosystems of the Nation to better understand where, how, and why the Nation's habitats change overtime.
