Terrestrial Positional Behavior of Wild Pongo pygmaeus
Contemporary Hunting Practices in a Mosaic Landscape of Tropical Forests and Plantations in West Kalimantan, Indonesia
In Indonesia, the expansion of labor-intensive plantations has transformed forested landscapes into forest-plantation mosaics, altering demographics through immigration and increasing access to forest resources. Understanding current hunting practices within these socially and ecologically altered landscapes is crucial for predicting how species of conservation concern will be affected. However, there is a lack of quantitative, site-based, multi-…
Terrestriality across the primate order
Terrestriality is relatively rare in the predominantly arboreal primate order. How frequently, and when, terrestriality appears in primate evolution, and the factors that influence this behavior, are not well understood. To investigate this, we compiled data describing terrestriality in 515 extant nonhuman primate taxa. We describe the geographic and phylogenetic distribution of terrestriality, including an ancestral state reconstruction estimati…
Future coexistence with great apes will require major changes to policy and practice
Assessing the state of knowledge of contemporary climate change and primates
In recent years, interest in understanding the effects of climate change on species and ecological systems has sharply increased. We quantify and contextualize the current state of knowledge about the effects of contemporary climate change on non‐human primates, a taxon of great ecological and anthropological significance. Specifically, we report findings from a systematic literature search designed to assess the allocation of research effort on …
Larger gains from improved management over sparing–sharing for tropical forests
Evidence for High Variability in Temporal Features of the Male Coda in Müller’s Bornean Gibbons (Hylobates muelleri)
Investigating Individual Vocal Signatures and Small-Scale Patterns of Geographic Variation in Female Bornean Gibbon (Hylobates muelleri) Great Calls
Multiple Ecological Factors Influence the Location of Proboscis Monkey (Nasalis larvatus) Sleeping Sites in West Kalimantan, Indonesia
Sleeping site selection by proboscis monkeys ( Nasalis larvatus ) in West Kalimantan, Indonesia
Primates spend at least half their lives sleeping; hence, sleeping site selection can have important effects on behavior and fitness. As proboscis monkeys (Nasalis larvatus) often sleep along rivers and form bands (aggregations of one male groups) at their sleeping sites, understanding sleeping site selection may shed light on two unusual aspects of this species' socioecology: their close association with rivers and their multilevel social organi…
Responses of Primates and Other Frugivorous Vertebrates to Plant Resource Variability over Space and Time at Gunung Palung National Park
African Primate Assemblages Exhibit a Latitudinal Gradient in Dispersal Limitation
Interspecific Interactions between Primates, Birds, Bats, and Squirrels May Affect Community Composition on Borneo
For several decades, primatologists have been interested in understanding how sympatric primate species are able to coexist. Most of our understanding of primate community ecology derives from the assumption that these animals interact predominantly with other primates. In this study, we investigate to what extent multiple community assembly hypotheses consistent with this assumption are supported when tested with communities of primates in isola…
Strategies for the Use of Fallback Foods in Apes
Researchers have suggested that fallback foods (FBFs) shape primate food processing adaptations, whereas preferred foods drive harvesting adaptations, and that the dietary importance of FBFs is central in determining the expression of a variety of traits. We examine these hypotheses in extant apes. First, we compare the nature and dietary importance of FBFs used by each taxon. FBF importance appears greatest in gorillas, followed by chimpanzees a…
Defining fallback foods and assessing their importance in primate ecology and evolution
Physical anthropologists use the term “fallback foods” to denote resources of relatively poor nutritional quality that become particularly important dietary components during periods when preferred foods are scarce. Fallback foods are becoming increasingly invoked as key selective forces that determine masticatory and digestive anatomy, influence grouping and ranging behavior, and underlie fundamental evolutionary processes such as speciation, ex…
Use of limestone karst forests by Bornean orangutans ( Pongo pygmaeus morio ) in the Sangkulirang peninsula, east Kalimantan, Indonesia
The Indonesian province of East Kalimantan is home to some of the largest remaining contiguous tracts of lowland Dipterocarp forest on the island of Borneo. Nest surveys recently conducted in these forests indicated the presence of a substantial population of Eastern Bornean orangutans ( Pongo pygmaeus morio ) in the Berau and East Kutai regencies in the northern half of the province. The Sangkulirang Peninsula contains extensive limestone karst …
Evolutionary Consequences of Fallback Foods
Urinary testosterone levels of wild male bonobos (Pan paniscus) in the Lomako Forest, Democratic Republic of Congo
We collected urine samples from seven male bonobos (Pan paniscus) in the Eyengo community, Lomako Forest, Democratic Republic of Congo, and assayed them for testosterone (T). T levels averaged 525 pmol/mg Cr in adult males, and 309 pmol/mg Cr in subadult males. We collected hormonal and behavioral data during a period of relative social instability following the recent arrival of two immigrant males. In concordance with predictions derived from t…
