Informing Protection Efforts for Critically Endangered Chimpanzees (Pan troglodytes verus) and Sympatric Mammals amidst ...
Published in Folia Primatologica
Updated information on Critically Endangered western chimpanzees (Pan troglodytes verus) in Senegal is urgently needed, given that gold mining is rapidly transforming landscapes and livelihoods. Specifically, biodiversity assessments will better elucidate the chimpanzee extinction risk here and yield baselines for monitoring. We compared mammal spe...
Activity Patterns of Captive Philippine Tarsiers (Tarsius syrichta): Differences Related to Sex and Social Context
Published in Folia Primatologica
Among tarsiers, nocturnal, obligatory faunivorous primates inhabiting islands of South-East Asia, the Philippine tarsier (Tarsius [= Carlito] syrichta) is one of the least studied. To date, activity patterns of this threatened species have not been the subject of any investigation. In the present study, we provide the first quantitative data on how...
Space Use by Eastern Hoolock Gibbons (Hoolock leuconedys) in Nankang, Mt. Gaoligong, Southwest Yunnan, China
Published in Folia Primatologica
To understand the differences in space use by eastern hoolock gibbons (Hoolock leuconedys) for meeting different behavioural needs and adapting to a disturbed environment, an eastern hoolock gibbon family in Nankang, Mt. Gaoligong, China, was observed, and data on their behaviour, spatial position and substrate use were collected through instantane...
Wild Chimpanzees Show a Decrease in Pant Grunting over Their First 6 Years of Life
Published in Folia Primatologica
Data from a large cross-sectional sample of wild chimpanzee mother-infant dyads yield evidence that young chimpanzees’ pant grunting unfolds nonlinearly over the early developmental period. Though infants begin pant grunting early, and mothers’ rates did not decrease, infant pant grunting declined as infants aged through infancy. Mother-infant dyad...
Assessing Public Perceptions and Solutions to Human-Monkey Conflict from 50 Years in Sri Lanka
Published in Folia Primatologica
Sri Lanka is a biodiversity hotspot with high human density that contributes to increasing human-monkey conflict (HMC). In 50 years of primate studies there, the development of HMC has been documented, and many workshops and interventions organized to ameliorate HMC. These activities prompted the present survey. In the extensive lowland dry zone of...
Within-Population Variations in Home Range Use and Food Patch Use of Japanese Macaques: A Perspective of Intergroup Host...
Published in Folia Primatologica
Behavioral mechanisms of intergroup feeding competition remain unclear, despite its importance as a benefit of group living. Japanese macaques in the coastal and highland forests of Yakushima, Japan, are ideal study subjects because the intensity of intergroup feeding competition differs without phylogenetic effects. We aimed to test whether macaqu...
Validation of a Noninvasive Hair Trapping Method for Extractive-Foraging Primates
Published in Folia Primatologica
Hair is a useful source of biological information. For example, the bulb can be a source of high-quality genetic material, whereas the shaft can be useful for measuring heavy metals and some hormones, such as cortisol. The stable isotope composition of hair is another valuable source of biological information. Consequently, noninvasive methods of h...
Energy (Im-)Balance in Frugivorous Lemurs in Southern Madagascar: A Preliminary Study in Lemur catta and Eulemur rufifro...
Published in Folia Primatologica
The reproductive cycle of several lemur species is synchronized by photoperiodic changes and it is attuned to the seasonal fluctuations in food supply. Nevertheless, irregular periods of food shortage occur in Madagascar, which can result in a negative energy balance and reduced fitness, especially in frugivorous species. Here, we tested whether ri...
Population Genetic Structure of an Endangered Endemic Primate (Leontopithecus chrysomelas) in a Highly Fragmented Atlant...
Published in Folia Primatologica
This study evaluated the genetic structure of wild populations of the endangered primate, Leontopithecus chrysomelas. We tested the assumption that populations of L. chrysomelas, given their larger population size and a higher degree of habitat continuity, would have higher genetic diversity and less genetic structuring than other lion tamarins. We...
