Revue de Primatologie, 2015 La reconnaissance auditive entre les membres d’un groupe est importante pour maintenir une cohésion socio-spatiale chez les espèces forestières où la visibilité dans l’habitat est limitée, mais cela peut aller au-delà du groupe chez les espèces ...

Differences in sperm morphology between Alouatta palliata and Alouatta pigra are consistent with the intensity of sperm competition in each species. [PDF]
Am J Primatol, 2023 AbstractThe intensity of sperm competition, in which sperm compete within the female reproductive tract to reach and fertilize her eggs, varies in species with different mating systems. Sperm competition is more intense in species where males cannot monopolize access to reproductive females and females mate with multiple males.

Spatial aggregation of fruits explains food selection in a neotropical primate (Alouatta pigra). [PDF]
Sci Rep, 2019 AbstractThe availability and spatial distribution of food resources affect animal behavior and survival. Black howler monkeys (Alouatta pigra) have a foraging strategy to balance their nutrient intake that involves mixing their consumption of leaves and fruits.

Habitat degradation impacts black howler monkey (Alouatta pigra) gastrointestinal microbiomes. [PDF]
ISME J, 2013 Abstract The gastrointestinal (GI) microbiome contributes significantly to host nutrition and health. However, relationships involving GI microbes, their hosts and host macrohabitats remain to be established. Here, we define clear patterns of variation in the GI microbiomes of six groups of Mexican black howler monkeys (Alouatta pigra)

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.

Clarifying the Cryptic Host Specificity of Blastocystis spp. Isolates from Alouatta palliata and A. pigra Howler Monkeys. [PDF]
PLoS ONE, 2017 Although the presence of cryptic host specificity has been documented in Blastocystis, differences in infection rates and high genetic polymorphism within and between populations of some subtypes (ST) have impeded the clarification of the generalist or ...

Salivary proteome of a Neotropical primate: potential roles in host defense and oral food perception [PDF]
PeerJ, 2020 Background Saliva contains a very complex mixture of proteins for defense against microbiological pathogens and for oral food perception. Howler monkeys are Neotropical primates that can consume a mostly leaf diet. They are well known to thrive in highly
