In a study recently published in the Proceedings of the National Academy of Sciences (PNAS), Professor Crooks led an international research team to quantify habitat fragmentation for Earth’s terrestrial mammals, including over 4000 species.
Results demonstrate that mammals with more fragmentation are at greater risk of extinction, even after accounting for the effects of key macroecological predictors such as body size and geographic range size. Species with higher fragmentation had smaller ranges and a lower proportion of high-suitability habitat within their range, and most high-suitability habitat occurred outside of protected areas, further elevating extinction risk. Quantification of habitat fragmentation will help guide strategic priorities for global mammal conservation. See CSU press release for more details.
