Summary
Three potentially competing bear species inhabit tropical Asia: the sloth bear (Melursus ursinus), sun bear (Helarctos malayanus), and Asiatic black bear (Ursus thibetanus). Sun bears (30–80 kg), the smallest species of bear in the world, are about half the size of black bears (65–150 kg) and sloth bears (55–145 kg). What factors generate the separation of sloth bears geographically from black and sun bears? What factors facilitate the extensive sympatry of black bears and sun bears? How are these patterns structured by evolutionary history and competition between bear species, and what mechanisms facilitate their coexistence or maintain their separation? Has current forest loss and degradation benefited one species over another? If so, has interspecific competition played a part? These questions are the focus of this chapter.
