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.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

The Effects of Dependent Infants on the Social Behavior of Mantled Howler Monkeys (Alouatta Palliate) [PDF]

, 2012
Six weeks of observation on eight groups of wild mantled howler monkeys revealed that the presence of a dependent infant alters the frequency of social interactions between a female with an infant and other adult monkeys.

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

Oikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

Population genetics and evolutionary history of the black howler monkey Alouatta pigra and hybrid populations in Mexico

Frontiers in Ecology and Evolution
Genetic diversity is of prime importance for biological diversity and for the long-term conservation and survival of species and populations. The conservation of hybrid individuals originating from natural hybridization is still controversial; nearly ...

Ripple Effects: Social Turmoil Following Infant Kidnapping Attempts in Wild Geladas

Ethology, EarlyView.
Graphical abstract illustrating the social consequences of infant kidnapping in wild geladas (Theropithecus gelada). The study monitors a 28‐day period divided into a 14‐day pre‐kidnapping phase and a 14‐day post‐kidnapping phase. ABSTRACT Infant kidnapping is an extreme social disruption reported in some primate species, yet its consequences on social
