Hyoid Bone Size and Its Implications for Social Organization and Sexual Selection in Alouatta pigra and the Elusive Alouatta macconnelli

Journal of Student Research, 2020
The purpose of this research paper is focusing on the hyoid bone in Alouatta pigra and Alouatta macconnelli and determine its role in affecting the social organization and sexual selection of the individuals in these species. This includes the discussion on the dimensions of the hyoid between the males and females as well as an analysis of observed ...

Local knowledge enhances the sustainability of interconnected fisheries

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our modelling approach allows managers to compare alternative conservation strategies under different socio‐ecological scenarios, highlighting trade‐offs and guiding investment of effort and resources. While immediately valuable for pirarucu management in the Middle Juruá, the framework scales across tiers of applicability, each requiring progressively

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.

River crossings by Ateles geoffroyi and Alouatta pigra in southern Mexico: A preliminary report [PDF]

Revista chilena de historia natural, 2010
Durante nueve meses evaluamos si los monos arana (Ateles geoffroyi) y los monos aulladores (Alouatta pigra) tenian la capacidad para cruzar uno de los rios mas grandes de Mexico, y si este comportamiento estaba relacionado con la deforestacion y/o el tamano de las poblaciones humanas en la margen alterada del rio. Este estudio se realizo a lo largo del

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 ...

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 ...

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 ...
