Sexual dimorphism in the loud calls of Azara’s owl monkeys (Aotus azarae): evidence of sexual selection? [PDF]

open access: yes, 2019
Primates use different types of vocalizations in a variety of contexts. Some of the most studied types have been the long distance or loud calls. These vocalizations have been associated with mate defense, mate attraction, and resource defense, and it ...

A Field‐Deployable eDNA Metabarcoding Workflow Including De Novo Reference Assembly for Characterising Understudied Biodiversity Hotspots

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Field‐deployable DNA metabarcoding offers a transformative approach to biodiversity research and monitoring, yet its application remains limited due to technical constraints and a lack of reference data in poorly studied ecosystems. Combining isothermal Recombinase Polymerase Amplification (RPA) and Oxford Nanopore sequencing, we introduce a ...

Las lianas como recurso alimentario para el mono aullador (Alouatta guariba) y el muriqui meridional (Brachyteles arachnoides) en un área forestal [PDF]

open access: yes, 2009
Las lianas (enredaderas leñosas) son muy abundantes y presentan una gran diversidad en las selvas tropicales; sin embargo no se ha tenido en cuenta su contribución relativa como fuente de alimento para los herbívoros.

Introducing TropiCam‐AI: A taxonomically flexible automated classifier of Neotropical arboreal mammals and birds from camera‐trap data

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 4, Page 1235-1247, April 2026.
Abstract Rapid, accurate assessment of arboreal vertebrates in tropical forests remains a bottleneck for large‐scale biodiversity monitoring, due to the challenges and effort associated with traditional survey methods. To bridge this gap, arboreal camera‐trapping is emerging as a promising way to observe otherwise elusive species, opening new avenues ...

Immunohistochemical and serological aspects of Toxoplasma gondii infection in Neotropical primates

open access: yesSemina: Ciências Agrárias, 2017
Toxoplasmosis, a disease caused by the intracellular coccidian Toxoplasma gondii that infects most warm-blooded vertebrates, is widely distributed and fatal for primates, which are peculiarly susceptible for unknown reason(s).

Environmental and Temporal Effects on Vocal Activity in a Nocturnal Primate: Implications for Passive Acoustic Monitoring

open access: yesAmerican Journal of Primatology, Volume 88, Issue 3, March 2026.
Passive acoustic monitoring of the Critically Endangered Nosy Be sportive lemur (Lepilemur tymerlachsoni) for two lunar cycles revealed that vocal activity (i.e., call rates) increased over a 4‐h sampling window starting at twilight. The lemurs also called more as temperature and moonlight increased, and called less when it rained.

Howl vocalisations of captive black and gold howler monkeys (Alouatta caraya); acoustics, function and applications for welfare [PDF]

open access: yes, 2013
This thesis aims to determine the function of howl vocalisations performed by the black and gold howler monkey, Alouatta caraya, and to examine the connections between howling, welfare and breeding in captivity.
