Arboreal route navigation in a Neotropical mammal: energetic implications associated with tree monitoring and landscape attributes

Movement Ecology, 2019
Background Although navigating along a network of routes might constrain animal movement flexibility, it may be an energetically efficient strategy. Routinely using the same route allows for visually monitoring of food resources, which might reduce the ...

Species‐level exploration of the gut microbiome in the leaf‐eating Presbytis monkeys reflected the effects of anthropogenic activity and specialized dietary niches: Conservation on the fourth biodiversity level

iMetaOmics, Volume 2, Issue 4, December 2025.
This study integrates full‐length 16S rRNA and deep metagenomic sequencing to explore species‐level gut microbial composition and function in two endangered leaf‐eating langur species—white‐headed langurs and François' langurs—across gradients of human disturbance.

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

Journal of Animal Ecology, Volume 94, Issue 12, Page 2687-2703, December 2025.
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 ...

Parasites, primates, and ant-plants: Clues to the life cycle of Controrchis spp. in Black Howler Monkeys (Alouatta pigra) in southern belize

, 2020
The purpose of this study was to investigate the prevalence, intensity, and possible transmission routes of the trematode, Controrchis spp. (Dicrocoeliidae), in a population of black howler monkeys (Alouatta pigra) near Monkey River, Belize.

Global comparison of habitat intactness models for predicting extinction risk in terrestrial mammals

Ecography, Volume 2025, Issue 11, November 2025.
The effects of habitat condition on biodiversity have primarily been investigated using discrete (patch‐matrix) habitat models, which consider habitat fragments as islands embedded in an inhospitable matrix. Recently, continuum habitat models, which focus on ecological gradients without defining habitat or matrix, have emerged.

Neopterin as a Tool for Primate Ecoimmunology: Current Knowledge, Practical Application, and New Directions From Captivity to the Wild

American Journal of Primatology, Volume 87, Issue 10, October 2025.
Neopterin is a sensitive and specific biomarker of intracellular pathogen infection and chronic inflammation, and affected by environmental, life‐history, and sex‐contextual factors. This review offers best‐practice guidelines and practical advice on sample collection, storage, and analysis in primates when used for ecoimmunological conservation and ...

The feeding ecology of translocated howler monkeys, Alouatta pigra, in Belize

, 1998
The feeding ecology of translocated black howler monkeys (Alouatta pigra) was studied in Belize, Central America. Data collection began in March 1994, in the Community Baboon Sanctuary (CBS), in northern Belize.

How does a howler monkey Alouatta pigra choose what to eat and where to sleep during the day?

Animal Biodiversity and Conservation
Studies of primate behavior have focused on animals independently of their interactions with their environment, ignoring critically important interactions with plants other than feeding.

Look past the cooperative eye hypothesis: reconsidering the evolution of human eye appearance

Biological Reviews, Volume 100, Issue 5, Page 2038-2054, October 2025.
ABSTRACT The external appearance of the human eye has been prominently linked to the evolution of complex sociocognitive functions in our species. The cooperative eye hypothesis (CEH) proposes that human eyeballs, with their weakly expressed conjunctival and scleral pigmentation, are uniquely conspicuous and evolved under selective pressures to behave ...
