TL;DR: It is concluded that a substantial improvement in the quality of model predictions can be achieved if uneven sampling effort is taken into account, thereby improving the efficacy of species conservation planning.
Journal ArticleDOI
Evolutionary Consequences of Fallback Foods
TL;DR: The assumption that fallback foods play an important role in shaping morphological adaptations, behavior, and socioecology in primates is examined and it is suggested that preferred resources tend to drive adaptations for harvesting foods.
Journal ArticleDOI
Defining fallback foods and assessing their importance in primate ecology and evolution.
TL;DR: This article begins by comparing two recently published conceptual frameworks for considering the evolutionary significance of fallback foods and proposes a way in which these approaches might be integrated, and considers a series of questions about the importance of fall back foods for primates.
Journal ArticleDOI
Distribution and conservation status of the orang-utan (Pongo spp.) on Borneo and Sumatra: how many remain?

TL;DR: In this article, a comprehensive survey of all survey data produced a comprehensive picture of orang-utan distribution on both Borneo and Sumatra, and the results indicated that in 2004 there were c. 6,500 P. abelii remaining on Sumatra and at least 54,000 P. pygmaeus on both islands.
Journal ArticleDOI
Does learning affect the structure of vocalizations in chimpanzees
TL;DR: Within-group variation in call structure of the captive groups was similar to that found in a group of wild Ugandan chimpanzees, suggesting the presence of species-specific constraints on this call within which different populations can converge on local variants.
