Abstract Genomic data are increasingly used in primatology to understand how landscape features, dispersal patterns, and historical processes shape population structure and conservation-relevant diversity. The gelada ( Theropithecus gelada ), an endemic primate of the Ethiopian highlands, is currently divided into three subspecies; yet little is known about the extent of genomic variation within …

Abstract Wildlife monitoring is essential for guiding biodiversity conservation strategies, particularly in fragmented ecosystems under intense anthropogenic pressure. While noninvasive methods, such as camera traps, are widely used for terrestrial species, their application in other forest strata is underexplored despite its potential for studying elusive and nocturnal arboreal mammals. We aim t…

Abstract The study of vocal development in non-human primates is crucial to understanding developmental trajectories and distinguishing innate from acquired vocal traits. Recent studies show that young female gibbons co-sing with their mothers, but these interactions decline as females become more independent. We studied the development of the great call, including notes and twitter sounds, in fi…

Abstract Grooming in primates is often structured by dominance rank and exchanged for rank-related benefits under conditions of high feeding competition. However, evidence suggests that such patterns may weaken in environments with abundant and nonmonopolizable resources. We investigated grooming patterns among adult female Sapajus nigritus cucullatus living in an urban forest fragment characteri…

Abstract The energy and nutrient costs associated with body mass, age, and sex can influence variation in primate behavior and diet. However, comparatively little is known about how these factors affect the behavioral and dietary flexibility of Asian colobines in response to intra-annual climate shifts. We collected data on an isolated population of black-and-white snub-nosed monkeys ( Rhinopithe…

Abstract All primate species produce vocalizations for complex communication, conveying a wide range of information, regulating social interactions, coordinating activities, and serving as antipredator strategies. Together, these vocalizations form a species' vocal repertoire. However, despite their widespread presence and ecological significance, the vocal repertoires of less than 15% of primate…
