Zoonotic Parasites in Marmosets (Callithrix Spp.) From Southern Brazil: Insights From a One Health Perspective. [PDF]

J Med Primatol
ABSTRACT Background Currently, six species of Callithrix are frequently observed in anthropized and degraded environments in different regions of Brazil. This occupation favors interactions with humans and increases the risk of infection by parasites with zoonotic potential.

Vocalizations Reveal Species Differences in Endangered Lion Tamarins (Primates, Callitrichidae). [PDF]

Am J Primatol
Spectral parameters of vocalizations distinguish lion tamarin species. Peak frequency, center frequency, and frequency at 5% and 95% were the most informative measures for separating species, with the trill being the vocalization that showed the most differences, and Leontopithecus caissara being the most distinct species of all.

Supplementation With Human Foods Affects the Gut Microbiota of Wild Howler Monkeys. [PDF]

Am J Primatol
ABSTRACT Wild primates face a wide range of anthropogenic influences globally that impact their health, fitness, and survival. One area of potential impact that has been particularly understudied is the supplementation of wild primate diets with human foods.

Environmental Stress and the Primate Microbiome: Glucocorticoids Contribute to Structure Gut Bacterial Communities of Black Howler Monkeys in Anthropogenically Disturbed Forest Fragments

Frontiers in Ecology and Evolution, 2022
Animals living in anthropogenically disturbed habitats are exposed to environmental stressors which can trigger physiological reactions, such as chronic elevations of glucocorticoid hormones. Physiological responses to stressors may induce changes in the

Risk factors connected to gastrointestinal parasites in mantled Alouatta palliata mexicana and black howler monkeys Alouatta pigra living in continuous and in fragmented rainforests in Mexico

Environmental Epigenetics, 2012
In this study we document the prevalence of gastrointestinal parasites (helminths and protozoans) found in fecal samples of populations of Alouatta palliata mexicana and of A.

Seasonal Adaptation of the Gut Microbiome in Japanese Macaques: Linking Gut Microbiome Shifts With Fermentative Function. [PDF]

Ecol Evol
Seasonal dietary shifts in Japanese macaques drive changes in gut microbiome composition and function. While overall diversity remains stable, microbial communities adapt by modulating fermentative processes, ensuring efficient and stable energy extraction from leaves while responding flexibly to non‐leaf foods.

Registros ocasionales de Alouatta seniculus (Primates: Atelidae) en sabanas de la Orinoquia colombiana, San Martín de los Llanos, Meta, Colombia

Mammalogy Notes, 2021
Se ha considerado que la matriz del paisaje actúa como una barrera que influye en la dispersión, diversidad y persistencia de algunas especies de fauna, pero su importancia no ha sido evaluada en detalle para primates arborícolas.

Estado poblacional del saraguato negro (Alouatta pigra) en la Reserva de la Biosfera Pantanos de Centla

Ecosistemas y Recursos Agropecuarios, 2021
 La conservación de especies silvestres requiere implementar acciones basadas en el tamaño, composición y distribución de sus poblaciones. Esta información, sin embargo, está incompleta o desactualizada para muchas áreas de gran importancia biológica ...

The role of sex and age in the architecture of intrapopulation howler monkey-plant networks in continuous and fragmented rain forests [PDF]

PeerJ, 2016
We evaluated the structure of intrapopulation howler monkey-plant interactions by focusing on the plant species consumed by different sex and age classes in continuous and fragmented forests in southern Mexico.

Effects of variation in forest fragment habitat on black howler monkey demography in the unprotected landscape around Palenque National Park, Mexico [PDF]

PeerJ, 2020
Habitat loss and fragmentation are leading threats to biodiversity today, and primates are particularly vulnerable to anthropogenic habitat disturbance.
