Low genetic diversity and limited genetic structure across the range of the critically endangered Mexican howler monkey (Alouatta palliata mexicana) [PDF]
American Journal of Primatology, 2020 AbstractGenetic diversity provides populations with the possibility to persist in ever‐changing environments, where selective regimes change over time. Therefore, the long‐term survival of a population may be affected by its level of genetic diversity. The Mexican howler monkey (Alouatta palliata mexicana) is a critically endangered primate restricted ...

Social correlates of variation in urinary oxytocin concentrations of mantled howler monkeys Alouatta palliata (Gray, 1849) (Primates: Atelidae): A preliminary assessment [PDF]
, 2021 There is growing evidence that non-human primate sociality is linked to proximate neuroendocrine mechanisms. Arginine vasopressin, endorphins, and oxytocin may be involved in such mechanisms.

Male Reproductive Strategies in Black and Gold Howler Monkeys (Alouatta caraya) [PDF]
, 2013 Behavioral and demographic factors such as group size, social structure, dispersal patterns, and mating systems affect male reproductive success. In the present study, we analyze the relationship between social structure, genetic relatedness of adult ...

Socioecological correlates of social play in adult mantled howler monkeys [PDF]
, 2022 The study of animal play is highly complex since its potential functions vary with social and environmental circumstances. Although play is generally characteristic of immature animals, it may persist in adults in its social form, particularly when ...

Howler Monkeys (Alouatta palliata mexicana) Produce Tannin-Binding Salivary Proteins
International Journal of Primatology, 2015 Dietary tannins are ubiquitous in woody plants and may have serious negative effects on herbivores by inducing a loss of dietary protein and producing toxins if they are hydrolyzed in the gut. Many herbivorous mammals counter the negative effects of tannins through tannin-binding salivary proteins (TBSPs) that inactivate tannins by forming insoluble ...

Abnormal pelage color in mantled howler monkey (Alouatta palliata mexicana) in Veracruz, México
Therya notes, 2021 El leucismo es una despigmentación total o parcial del pelaje, mientras que el albinismo es la pérdida total de pigmentos en el cuerpo entero; las condiciones anormales de la carencia del pigmento se deben a la expresión de genes recesivos. Se realizó una expedición ad libitum en el Ejido Álvaro Obregón, al suroeste de Nuevo Cantón, municipio de ...

Gastrointestinal parasites in captive and free-ranging Cebus albifrons in the Western Amazon, Ecuador [PDF]
, 2017 Currently, there is a lack of surveys that report the occurrence of gastrointestinal parasites in the white-headed capuchin monkey (Cebus albifrons). We therefore assessed the presence and richness (= number of different parasite genera) of parasites in ...
