Rensch’s and Bergmann’s Rules in Cis-Andean South-American Howler Monkeys (Mammalia: Alouatta) [PDF]
, 2018 Howler monkeys (genus Alouatta) are large folivorous primates living in South America. We tested for the application of both Rensch’s rule and Bergmann’s rule to body size variation in Alouatta. We found that Rensch’s rule does apply in howlers.

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 ...

American Journal of Primatology, Volume 87, Issue 6, June 2025.Infant being handled by mother. ABSTRACT A range of ecological and social factors have been shown to affect early‐life behaviour in mammals. Primate infants are altricial and thus unable to move independently at birth. As a result, infants in some species are continuously held or carried (handled) by their mother or another caregiver (allomother ...

Sexual dimorphism in the loud calls of Azara’s owl monkeys (Aotus azarae): evidence of sexual selection? [PDF]
, 2019 Primates use different types of vocalizations in a variety of contexts. Some of the most studied types have been the long distance or loud calls. These vocalizations have been associated with mate defense, mate attraction, and resource defense, and it ...

Genetic Variation of Mantled Howler Monkeys (Alouatta palliata) from Costa Rica1 [PDF]
BIOTROPICA, 2003 ABSTRACTWe examined genetic diversity of howler monkeys (Alouatta palliata) from Costa Rica. Blood samples of howler monkeys were collected at various locations in Costa Rica, and electrophoresis of total plasma proteins yielded no variation. We also conducted starch gel electrophoresis of red cell isozymes and did not find variation for any of the 14 ...

American Journal of Primatology, Volume 87, Issue 5, May 2025.Mitochondrial DNA analysis suggests that founder‐event speciation played a key role in the divergence between cis‐Andean and trans‐Andean clades, as well as in the diversification of cis‐Andean lineages. Ancestral range reconstruction using mitochondrial genomes indicates that the most recent common ancestor of Alouatta had a widespread distribution ...
