MHC class II DRB variability in wild black howler monkeys (Alouatta pigra), an endangered New World primate [PDF]

Animal Biodiversity and Conservation, 2018
The genes of the major histocompatibility complex (MHC) are the most important genetic component of the immune system in vertebrates. Their variability is known to influence a species’ ability to recognize and respond to pathogens.

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

Climatic–Anthropogenic Synergy Drives Escalating Minimum Area Requirements and Connectivity‐Protection Mismatch in a Karst‐Endemic Primate

Integrative Zoology, EarlyView.
Climate change and anthropogenic activities drive antagonistic degradation of landscape connectivity for endangered François’ langur (1987–2024), causing 48.8% habitat loss, north‐south fragmentation, and centroid migration (1.2 km/yr). Despite protected areas buffering connectivity, static management fails dynamic priority habitats; we propose ...

Gut Microbiota of Gray Snub‐Nosed Monkeys: Adaptation to Seasonal Variations Through Energy Compensation and Thermogenesis

Integrative Zoology, EarlyView.
Based on metagenome‐assembled genomes (MAGs), the gut microbiota of the gray snub‐nosed monkeys recovered 1229 non‐redundant MAGs. The gut microbiota showed an enhanced capacity to produce energy substrates with increased conversion activity of these substrates during winter.

Microbial Variability in Zoo‐Housed Alaotran Gentle Lemurs: Host‐Associated Factors and Environmental Influences

American Journal of Primatology, Volume 88, Issue 8, August 2026.
Environmental variation is associated with gut microbiota differences in zoo‐housed endangered lemurs. ABSTRACT Primates worldwide face escalating ecological pressures, driving many species to rapid declines. Modern zoos play an essential role by maintaining viable populations and improving welfare through research‐driven management.

Flotation techniques (FLOTAC and mini-FLOTAC) for detecting gastrointestinal parasites in howler monkeys

Parasites & Vectors, 2017
Background Analyses of environmental correlates of the composition of gastrointestinal parasite communities in black howler monkeys (Alouatta pigra) have been hindered by inadequate calibration techniques of detection and quantification methods of the ...

“Variable Effects of Tourist Presence on the Activity Budget of Alouatta pigra ”

Tropical Conservation Science, 2023
Background and Research Wildlife tourism has been considered a useful tool for conservation in some contexts and found to cause diverse effects on biodiversity. We investigated the effect of the number of tourists on wild black howler monkeys’ ( Alouatta pigra) behavior at the Montes Azules Biosphere Reserve ...
