Supplementation With Human Foods Affects the Gut Microbiota of Wild Howler Monkeys. [PDF]

Am J Primatol
ABSTRACT Wild primates face a wide range of anthropogenic influences globally that impact their health, fitness, and survival. One area of potential impact that has been particularly understudied is the supplementation of wild primate diets with human foods.

Vocalizations Reveal Species Differences in Endangered Lion Tamarins (Primates, Callitrichidae). [PDF]

Am J Primatol
Spectral parameters of vocalizations distinguish lion tamarin species. Peak frequency, center frequency, and frequency at 5% and 95% were the most informative measures for separating species, with the trill being the vocalization that showed the most differences, and Leontopithecus caissara being the most distinct species of all.

Environmental Stress and the Primate Microbiome: Glucocorticoids Contribute to Structure Gut Bacterial Communities of Black Howler Monkeys in Anthropogenically Disturbed Forest Fragments

Frontiers in Ecology and Evolution, 2022
Animals living in anthropogenically disturbed habitats are exposed to environmental stressors which can trigger physiological reactions, such as chronic elevations of glucocorticoid hormones. Physiological responses to stressors may induce changes in the

A Macaque Model for the Effects of Hybridization on Body Size. [PDF]

Am J Biol Anthropol
Virtual measurements from CT scans of living monkeys were used to capture size and shape data on the effects of hybridization in size and variation. ABSTRACT Objectives Genomics research has uncovered recurrent hybridization between hominin species, yet its morphological impact remains understudied.

Edge effects and social behavior in three platyrrhines. [PDF]

Am J Primatol
Abstract Social behavior is a key adaptation for group‐living primates. It is important to assess changes to social behavior in human‐impacted landscape zones to better understand the impact of anthropogenic disturbance on primate species. We investigated social behavior rate and type in three species of platyrrhines across 100 m anthropogenic edge and

Impact of animal socioecology on gut microbial communities: Insights from wild meerkats in the Kalahari. [PDF]

J Anim Ecol
Our study addresses critical gaps at the nexus of animal and microbial ecologies, adding much‐needed empirical support to recent theoretical frameworks that have conceptualised gut microbiomes as being strongly influenced by animal sociality and group‐living, and bringing benefits that may have strongly (and reciprocally) influenced the evolution of ...

Risk factors connected to gastrointestinal parasites in mantled Alouatta palliata mexicana and black howler monkeys Alouatta pigra living in continuous and in fragmented rainforests in Mexico

Current Zoology, 2012
In this study we document the prevalence of gastrointestinal parasites (helminths and protozoans) found in fecal samples of populations of Alouatta palliata mexicana and of A.

Seasonal Adaptation of the Gut Microbiome in Japanese Macaques: Linking Gut Microbiome Shifts With Fermentative Function. [PDF]

Ecol Evol
Seasonal dietary shifts in Japanese macaques drive changes in gut microbiome composition and function. While overall diversity remains stable, microbial communities adapt by modulating fermentative processes, ensuring efficient and stable energy extraction from leaves while responding flexibly to non‐leaf foods.

Reconnaissance auditive intergroupe chez les mâles de singes hurleurs noirs (Alouatta pigra) sauvages

Revue de Primatologie, 2015
La reconnaissance auditive entre les membres d’un groupe est importante pour maintenir une cohésion socio-spatiale chez les espèces forestières où la visibilité dans l’habitat est limitée, mais cela peut aller au-delà du groupe chez les espèces ...
