Relative abundance and distribution of black-and-white colobus monkey (Colobus guereza guereza) in northwestern Ethiopia
Forest loss, fragmentation, and degradation are major threats to primates. In areas that have been heavily deforested, it is critical to identify the...

Black-and-white pelage as visually protective coloration in colobus monkeys
AbstractConspicuous coloration is often seen as the evolutionary consequence of either sexual selection or warning predators visually about prey...

Population Status of the Critically Endangered Preuss’s Red Colobus Monkey (Piliocolobus preussi Matschie 1900) and Recommendations for Its Conservation
Overhunting and habitat loss from the expansion of agriculture and extractive industries are the primary threats to primate species, 65% of which are...

Feeding Ecology of Omo River Guerezas (Colobus guereza guereza) in Natural Versus Plantation Forests in the Central Highlands of Ethiopia
Understanding the impacts of habitat modification on primate feeding ecology is essential to design effective conservation management strategies. The...

Social network dynamics, infant loss, and gut microbiota composition in female Colobus vellerosus during time periods with alpha male challenges
The gut microbiota of group-living animals is strongly influenced by their social interactions, but it is unclear how it responds to social...

Tight quarters: ranging and feeding competition in a Colobus angolensis ruwenzorii multilevel society occupying a fragmented habitat
AbstractMultilevel societies (MLSs) are present in several animal clades and our understanding of them is growing at a time with increasing habitat...

Primate population dynamics in Ngogo, Kibale National Park, Uganda, over nearly five decades
Many anthropogenic-driven changes, such as hunting, have clear and immediate negative impacts on wild primate populations, but others, like climate...

Selective deforestation and exposure of African wildlife to bat-borne viruses
Proposed mechanisms of zoonotic virus spillover often posit that wildlife transmission and amplification precede human outbreaks. Between 2006 and...

Longitudinal changes in the targets of chimpanzee (Pan troglodytes) hunts at Mahale Mountains National Park: how and why did they begin to intensively hunt red colobus (Piliocolobus rufomitratus) in the 1980s?
The hunting activities of chimpanzees ( Pan troglodytes ) at Mahale Mountains National Park exhibited a significant change over a 46-year observation...

Site Fidelity and Home Range Shifts in a Leaf-Eating Primate
The ability to move allows animals to optimize their fitness by responding to spatial variability in their environment, such as changes in the...

Microhabitat Use in Angolan Colobus Monkeys (Colobus angolensis ruwenzorii) at Nabugabo, Uganda Demonstrates Intraspecific Variability
Large-scale anthropogenic changes to the environment are making it vital to investigate habitat use so that we can better understand species’ basic...

Frequent predation on primates by crowned eagles (Stephanoaetus coronatus) in Mahale Mountains National Park, Tanzania
The significance of raptor predation has been repeatedly emphasized in studies on arboreal primates; however, there are few studies on the predation...

Feeding Ecology of the Omo River Guereza (Colobus guereza guereza) in Habitats with Varying Levels of Fragmentation and Disturbance in the Southern Ethiopian Highlands
Dietary responses to the habitat heterogeneity resulting from anthropogenic disturbance vary among primates. Some species alter their foraging...

Examining primate community occurrence patterns in agroforest landscapes using arboreal and terrestrial camera traps
ContextForest-agricultural mosaics are now considered critical for biodiversity. Within these landscapes, the type of land use surrounding remnant...

Masticatory and ingestive effort in Procolobus verus, a small-bodied African colobine
The olive colobus ( Procolobus verus ) is the smallest extant colobine. Based on the axiom that folivory is associated with larger body mass, the olive...

Selecting between iron-rich and clay-rich soils: a geophagy field experiment with black-and-white colobus monkeys in the Budongo Forest Reserve, Uganda
Geophagy, the intentional consumption of soil, has been observed in humans and numerous other animal species. Geophagy has been posited to be...

Assessing the effects of survey-inherent disturbance on primate detectability: Recommendations for line transect distance sampling
Habitat destruction and over-hunting are increasingly threatening the arboreal primates of Central Africa. To establish effective conservation...

Friends in high places: Interspecific grooming between chimpanzees and primate prey species in Budongo Forest
While cases of interspecies grooming have been reported in primates, no comprehensive cross-site review has been published about this behavior in...

Sr/Ca ratios indicate frugivory versus folivory in primates: a case study using handheld XRF in Kibale National Park, Uganda
Researchers often use trace element concentrations, including strontium–calcium ratios (Sr/Ca), to reconstruct paleodiets. While most commonly used...

Hunting of mammals by central chimpanzees (Pan troglodytes troglodytes) in the Loango National Park, Gabon
The predation and consumption of animals are common behaviours in chimpanzees across tropical Africa. To date, however, relatively little is known...
