Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Humans and platyrrhines share a pattern of articular variance

The Anatomical Record, EarlyView.
Abstract Previous work has identified a pattern of articular shape variation in modern human limb joints, in which convex joint surfaces exhibit constrained variance relative to their more variable concave conarticulars. This pattern is notable given that joint morphogenesis is influenced by local biomechanical environments, which vary substantially ...

Environmental factors associated With Toxoplasma gondii Exposure in Neotropical Primates of Costa Rica

Frontiers in Veterinary Science, 2020
The apicomplexan parasite Toxoplasma gondii (T. gondii) has been found in more than 350 species of homoeothermic vertebrates in diverse climates and geographic areas. In most animals, T. gondii produces mild or asymptomatic infection.

Passive acoustic monitoring for the estimation of density of the singing lemur (Indri indri)

Conservation Science and Practice, EarlyView.
Passive acoustic monitoring (PAM) was applied to estimate the density of indri (Indri indri) in the Maromizaha tropical forest by adapting a density‐estimation framework originally developed for marine environments. Using a network of autonomous recorders and GLMMs incorporating directional and environmental covariates, we estimated detection ...

Population genetics and evolutionary history of the black howler monkey Alouatta pigra and hybrid populations in Mexico

Frontiers in Ecology and Evolution
Genetic diversity is of prime importance for biological diversity and for the long-term conservation and survival of species and populations. The conservation of hybrid individuals originating from natural hybridization is still controversial; nearly ...

Mechanical Defenses in Leaves Eaten by Costa Rican Howling Monkeys (Alouatta palliata) [PDF]

American Journal of Physical Anthropology, 2005
Primate species often eat foods of different physical properties. This may have implications for tooth structure and wear in those species. The purpose of this study was to examine the mechanical defenses of leaves eaten by Alouatta palliata from different social groups at Hacienda La Pacifica in Costa Rica.

Contemporary Management of Human‐Caused Hybridization in Mammals: A Review

Mammal Review, Volume 56, Issue 4, December 2026.
By reviewing studies on human‐mediated (i.e., anthropogenic) hybridization, we identify key management gaps, including inconsistent identification of admixed individuals, limited population‐level assessments, insufficient social engagement, and unclear management objectives.
