Primate dominance hierarchies
Comprendre les causes et les conséquences des hiérarchies de dominance est l’un des principaux objectifs des études sur l’évolution sociale, la primatologie et l’anthropologie. Plusieurs théories ont été proposées au fil des ans pour expliquer les hiérarchies de dominance chez les primates, chacune faisant l’objet d’un nombre considérable de tests empiriques. Cependant, ces tests font encore l’objet de débats et manquent de cohérence quant aux fo…
Mantled howler monkeys avoid humans in response to both worker presence and noise intensity in an agroforestry system
Spider monkeys (Ateles geoffroyi) are vocally active throughout the night in a human-modified habitat
Coexistence Under Pressure
Global urbanization of nonhuman primate (hereafter primate) habitats is rapidly increasing the overlap between human and primate populations, often resulting in more frequent and complex human–primate interactions. While such interactions have been extensively documented for several terrestrial primate species, interactions are increasingly occurring with arboreal species, especially in highly urbanized touristic destinations. Here, we describe h…
Continuous Audio‐Visual Sensor Monitoring Is More Effective Than Human Observers for Detecting Moor Macaques
The number of species threatened with extinction is continuously increasing, underscoring the need for reliable population estimates to develop effective conservation plans. The ability to confirm a species' presence during surveys (i.e., detectability) is central for population estimates. While audio‐visual sensors, like camera traps and passive acoustic monitoring (PAM), have emerged as valuable tools for monitoring primates, few studies have s…
Let’s not use it! A dynamic no-use zone between the home ranges of two spider monkey groups
Howler Monkey Die‐Off in Southern Mexico
In May and June 2024, a die‐off of Mexican mantled howler monkeys ( Alouatta palliata mexicana ) occurred in southern Mexico. This commentary documents the event, attributing it to extreme heatwaves, drought, wildfires, and habitat impoverishment. Despite their reported resilience to habitat disturbances, mantled howler monkey mortality rate in some areas reached 31%. Key evidence points to heatstroke as the primary cause of death, exacerbated by…
Citizen’s Perceptions of Urban Black Howler Monkeys (Alouatta pigra) in the City of Palenque (Mexico)
Spider Monkeys (Ateles geoffroyi) Habituate to Anthropogenic Pressure in a Low-Impact Tourism Area
Effect of Anthropogenic Activities on the Population of Moor Macaques (Macaca maura) in South Sulawesi, Indonesia
Forest loss due to anthropogenic activities is one of the main causes of plant and animal species decline. Studying the species’ population status (i.e., density, abundance, and geographic distribution) on a regular basis is one of the main tools to assess the effect of anthropogenic activities on wildlife, to monitor population dynamics and to intervene with effective conservation strategies when the population of an endangered species declines.…
The impact of the establishment of Otoch Ma’ax Yetel Kooh protected area (Yucatán, Mexico) on populations of two neotropical primates
In 2002, Otoch Ma'ax Yetel Kooh (OMYK) was decreed a federal Flora and Fauna Protected Area in the state of Yucatn, Mexico, resulting in bans on hunting, logging and slash-and-burn agriculture within its limits. Our aim was to evaluate the influence of the establishment of the protected area on local primate populations. We compared relative abundances of Geoffroy's Spider Monkeys (Ateles geoffroyi) and Black Howler Monkeys (Alouatta pigra) in ma…
Sleep patterns, daytime predation, and the evolution of diurnal sleep site selection in lorisiforms
OBJECTIVES: Synthesize information on sleep patterns, sleep site use, and daytime predation at sleep sites in lorisiforms of Asia and Africa (10 genera, 36 species), and infer patterns of evolution of sleep site selection. MATERIALS AND METHODS: We conducted fieldwork in 12 African and six Asian countries, collecting data on sleep sites, timing of sleep and predation during daytime. We obtained additional information from literature and through c…
Changes in the primate trade in indonesian wildlife markets over a 25‐year period
Indonesia has amongst the highest primate species richness, and many species are included on the country's protected species list, partially to prevent over-exploitation. Nevertheless traders continue to sell primates in open wildlife markets especially on the islands of Java and Bali. We surveyed 13 wildlife markets in 2012-2014 and combined our results with previous surveys from 1990-2009 into a 122-survey dataset with 2,424 records of 17 speci…
Sleep patterns, daytime predation, and the evolution of diurnal sleep site selection in lorisiforms
