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 [PDF]
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.

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 Diagram of measurements taken on sperm cells. Sperm cells were stained with Eosin‐nigrosin, and images were taken at ×200 magnification with a Celestron Digital 5MP microscope camera. The embedded box in the bottom right corner shows the sperm cell without annotation and with a scale bar.

Hypopigmentation in mantled howler monkeys Alouatta palliata (gray 1849): First documented cases of whole-body leucism in South America. [PDF]
Ecol Evol, 2022 Hypopigmentation in vertebrates is the result of genetic impoverishment and it is associated with isolated populations and environmental stressors. In mantled howler monkeys Alouatta palliata (Gray 1849) there are records of hypopigmentation in Mexico and Costa Rica but this is the first documented record of whole‐body leucism in South America in a ...

The role of flower consumption in Howler Monkey Females’ diet: adjustment across reproductive states [PDF]
PeerJBackground Although the genus Alouatta is considered a folivore and frugivore species, the consumption of vegetative parts like flowers often represents a considerable percentage of their diet.

Multi-Species Canopy Latrines in Costa Rican Cloud Forests: A Mammal Interactions Hub in a Single Tree Species. [PDF]
Ecol EvolWe documented arboreal, multi‐species mammal latrines in montane cloud forests of Costa Rica by surveying 169 trees across 29 species. Latrines were found exclusively on Ficus tuerckheimii, with 11 occurrences across two mountain ranges and an additional observation in Honduras.

Diversity and Abundance of the Species of Arboreal Mammals in a Tropical Rainforest in Southeast Mexico. [PDF]
Ecol EvolArboreal camera trapping provides insights about mammals' community in a human‐modified landscape. High species richness in the area nourish the notion of HML as refuges for fauna. ABSTRACT Habitat loss threatens biodiversity worldwide being particularly detrimental in tropical rainforests where a cumulative deforestation expands for decades.

Howler monkey foraging ecology suggests convergent evolution of routine trichromacy as an adaptation for folivory. [PDF]
Ecol Evol, 2017 Primates possess remarkably variable color vision, and the ecological and social factors shaping this variation remain heavily debated. Here, we examine opsin genes, feeding behaviors, and reflectance of dietary foliage of wild mantled howler monkeys (Alouatta palliata).

Overview on the Role of Advance Genomics in Conservation Biology of Endangered Species. [PDF]
Int J Genomics, 2016 In the recent era, due to tremendous advancement in industrialization, pollution and other anthropogenic activities have created a serious scenario for biota survival. It has been reported that present biota is entering a “sixth” mass extinction, because of chronic exposure to anthropogenic activities.
