Comparing Population Census Methods for Howler Monkeys (Alouatta palliata) in a Fragmented Rainforest

Mammal Review, Volume 56, Issue 4, December 2026.
We compared two population census methods for howler monkeys (Alouatta palliata), the visual count and acoustic triangulation methods, and found both to be accurate at predicting population size. ABSTRACT Introduction Accurate population density estimates are important for guiding conservation management practices for threatened animal species.

Sit‐and‐Wait for the Agoutis: Dung Beetle Phoresy on Dasyprocta azarae in a Tropical Forest

Biotropica, Volume 58, Issue 6, November 2026.
ABSTRACT We document the first case of phoresy by dung beetles with a rodent, involving Canthon (Goniocanthon) smaragdulus subviridis and agoutis (Dasyprocta azarae). Camera traps set in a tropical forest recorded 21 phoretic events, with agoutis carrying 1–6 beetles each. This behavior likely enhances how beetles locate fresh dung.

Fecal and Salivary Cortisol Concentrations in Woolly (Lagothrix ssp.) and Spider Monkeys (Ateles spp.) [PDF]

, 2009
Detrimental physiological effects due to stressors can contribute to the low captive success of primates. The objective of this research was to investigate the potential impact of diet composition on cortisol concentrations in feces and saliva in woolly (

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, Volume 309, Issue 10, Page 2873-2896, October 2026.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

A global risk assessment of primates under climate and land use/cover scenarios [PDF]

, 2019
Primates are facing an impending extinction crisis, driven by extensive habitat loss, land use change, and hunting. Climate change is an additional threat, which alone or in combination with other drivers, may severely impact those taxa unable to track ...

Patch size, functional isolation, visibility and matrix permeability influences neotropical primate occurrence within highly fragmented landscapes. [PDF]

PLoS ONE, 2015
Forest fragmentation and habitat loss are among the major current extinction causes. Remaining fragments are mostly small, isolated and showing poor quality. Being primarily arboreal, Neotropical primates are generally sensitive to fragmentation effects.

Arboreal and Terrestrial Frugivore Vertebrate Assemblage Diversity and Composition Vary With Disturbance Histories in Guianan Forests

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study examined the impact of human disturbances on arboreal and terrestrial fruit‐consuming vertebrate assemblages across three tropical forest sites in French Guiana. While species richness remained consistent across sites, results revealed significant variations in visitation rates and a shift in dominant species.
