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 dietary guild (e.g., frugivore, folivore, insectivore, and ...

Population size and habitat preference of the Omo River guereza (Colobus guereza guereza) in a multi-habitat matrix in the central highlands of Ethiopia
Given the current rate of habitat degradation and loss in the tropics, data on primate population densities and habitat use are indispensable for assessing conservation status and designing feasible management...

Terrestrial Locomotion and Other Adaptive Behaviors in Howler Monkeys (Alouatta pigra) Living in Forest Fragments
Habitat loss threatens many primate species, yet some can thrive in small forest fragments. As forest loss increases due to anthropogenic land conversion or climate change, understanding the adaptive behaviors...

Open AccessLow Levels of Fruit Nitrogen as Drivers for the Evolution of Madagascar’s Primate Communities
The uneven representation of frugivorous mammals and birds across tropical regions – high in the New World, low in Madagascar and intermediate in Africa and Asia – represents a long-standing enigma in ecology....

High Energy or Protein Concentrations in Food as Possible Offsets for Cyanide Consumption by Specialized Bamboo Lemurs in Madagascar
Plants producing toxic plant secondary metabolites (PSMs) deter folivores from feeding on them. Animals that can cope with noxious PSMs have a niche with a competitive advantage over other species. However, th...

Ecological Flexibility as Measured by the Use of Pioneer and Exotic Plants by Two Lemurids: Eulemur collaris and Hapalemur meridionalis
Primate responses to habitat alteration vary depending on the species’ dietary guild and forest type. Leaves from secondary vegetation can provide nutritious resources to folivorous primates, whereas frugivore...

Predator avoidance and dietary fibre predict diurnality in the cathemeral folivore Hapalemur meridionalis
Though numerous mammalian taxa exhibit cathemerality (i.e. activity distributed across the 24-h cycle), this includes very few primates, exceptions being species from Aotinae and Lemuridae. Four non-mutually e...

Unusual slee** site selection by southern bamboo lemurs
Selection of slee** sites has consequences for individual fitness. Non-human primates often bias their selection towards arboreal sites, and the lemurs of Madagascar typically rest/sleep in trees, tree holes...

Cathemerality in a small, folivorous primate: proximate control of diel activity in Hapalemur meridionalis
A non-adherence to a strict diurnal or nocturnal activity cycle is prevalent among mammals, including taxa of Lemuridae, but rare among other primates. While non-mutually exclusive ecological hypotheses attemp...

Perseverance and food sharing among closely affiliated female chimpanzees
Chimpanzees (Pan troglodytes) have been frequently observed to share food with one another, with numerous hypotheses proposed to explain why. These often focus on reciprocity exchanges for social benefits (e.g., ...

Co** with low-quality diets: a first account of the feeding ecology of the southern gentle lemur, Hapalemur meridionalis, in the Mandena littoral forest, southeast Madagascar
Malagasy primates of the genus Hapalemur are exceptional in their exhibition of specialisations allowing for a folivorous diet despite their small body size. Members of this group are well known for their prefere...
