Habitat and social factors shape individual decisions and emergent group structure during baboon collective movement

eLife, 2017
For group-living animals traveling through heterogeneous landscapes, collective movement can be influenced by both habitat structure and social interactions. Yet research in collective behavior has largely neglected habitat influences on movement.

Abundance, Species Diversity, and Distribution of Diurnal Mammals in Humbo Community-Based Forest Area, Southern Ethiopia

International Journal of Zoology, 2020
This study was undertaken with the intention of assessing abundance, species diversity, and distribution of medium and large diurnal mammals at the Humbo Community Based Forest Area, Ethiopia. The study area was stratified into three major habitats based

Does ulnar curvature covary with locomotion and substrate use in cercopithecids?

Journal of Anatomy, Volume 249, Issue 2, Page 383-400, August 2026.
This study investigates ulnar curvature in cercopithecids in relation to locomotor behaviors, introducing an analysis of anteroposterior and mediolateral curvature, using geometric morphometric on 167 specimens (23 species). Although the two curvatures distinguish arboreal and terrestrial quadrupeds, their moderate covariation suggests that they ...

A Comparative Study of Aging and Cortical Folding in Chimpanzees and Olive Baboons

American Journal of Primatology, Volume 88, Issue 7, July 2026.
This figure shows 3D renderings of a chimpanzee (top) and olive baboon (bottom) brain with each sulcus label used in this study. After sulci were labeled, we exported metrics including mean depth and fold opening (width) of each sulcus to examine age‐related changes in these measures, as well as sex differences within species.

Investigating primate densities and human-primate conflict in Tembaro Community Conserved Forest, Omo River Basin, Ethiopia

BMC Zoology
Background Human-primate conflict is a global conservation challenge, particularly in densely populated, low-income countries like Ethiopia. The Omo River Valley forest belt, spanning across the Omo River in Ethiopia to Lake Turkana in Kenya, harbors a ...

Markers of hepatitis E among the population of the Greater Sochi and in monkeys of the Adler primate center

Вопросы вирусологии, 2016
Serum from humans (n = 646) and monkeys (n = 1867) collected during the period 1999-2013 was tested by enzyme immunoassay. Anti-HEV IgG was detected significantly more frequently (P ≥ 0.001) in rhesus macaques (Macaca mulatta) - 45.1 ± 1.6% (n = 1001 ...

Comparable Overall Copulation Rates Yet Rank‐Biased Access to Likely Fertile Females in Male Bonobos at Wamba

American Journal of Biological Anthropology, Volume 190, Issue 3, July 2026.
ABSTRACT Objectives Female bonobos (Pan paniscus) resume sexual swellings in the early postpartum stage and exhibit prolonged sexual receptivity. Despite the simultaneous availability of receptive females, genetic evidence reveals a pronounced male reproductive skew in this species.

Seasonal Dynamics of Resource Availability and Human Presence Shape Habitat Use of Large Carnivores in Chad

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Seasonal variation in resource availability and human activity can strongly influence large carnivore space use, yet these dynamics remain poorly documented in Central African savannas. Using dry and wet season camera‐trap surveys in Zakouma National Park, Chad, we show that prey availability drives carnivore space use in the dry season, and that ...

Farmers survey of wild mammals species implicated in crop damage in the Okapi Wildlife Reserve (OWR-Epulu, Democratic Republic of the Congo): severity and control strategies

Nature Conservation Research: Заповедная наука, 2018
Investigations on mammal species implicated in crop damage and control techniques used to protect fields was carried out in the Okapi Wildlife Reserve (OWR). The aim of this study was to identify mammal species causing damages on crops, the growth stages

Cercopithecid Monkeys From the Pleistocene Markaytoli Site at Ledi‐Geraru, Afar Region, Ethiopia

American Journal of Biological Anthropology, Volume 190, Issue 2, June 2026.
ABSTRACT Objectives Cercopithecid monkeys are ubiquitous across much of sub‐Saharan Africa today, where they contribute much to the ecological and taxonomic diversity seen in modern African primate communities. Plio‐Pleistocene assemblages from eastern Africa also preserve a rich cercopithecid fossil record, albeit one dominated by papionins and by ...
