Which intrinsic traits predict vulnerability to extinction depends on the actual threatening processes

摘要: Understanding what makes some species more vulnerable to extinction than others is an important challenge for conservation. Many comparative analyses have addressed this issue exploring how intrinsic and extrinsic traits associate with general estimates of vulnerability. However, these do not consider the actual threats that drive hence, are difficult translate into effective management. We provide updated description types spatial distribution affect mammals globally using data from IUCN 5941 mammals. Using we explore links between specific in order identify key features associated particular drivers extinction. find families formed by small-size habitat specialists likely be threatened habitat-modifying processes; whereas, larger small litter sizes processes directly survival. These results highlight importance considering threatening process studies. also discuss need standardize rank threat global assessments such as Red List improve our ability understand others.
