Collective group movement and leadership in wild black howler monkeys (Alouatta pigra)
Behavioral Ecology and Sociobiology, 2012Maintaining social cohesion through coordinating traveling time and direction is a primary benefit of group living in mammals. During a 15-month study, we investigated socioecological factors underlying leadership of collective group movements in three multimale–multifemale groups of black howler monkeys (Alouatta pigra) at Palenque National Park (PNP),

Group Structure and Dynamics in Black Howlers (Alouatta pigra): A 7-year Perspective
International Journal of Primatology, 2015The long-term monitoring of group structure and dynamics is critical to the study of primate ecology and evolutionary processes, as well as to understand the responses of individuals to changes in their environments. We monitored individually recognized black howlers (Alouatta pigra) belonging to 11 groups for 7 yr in different habitats and landscapes ...

Female participation in collective group defense in black howler monkeys (Alouatta pigra)
American Journal of Primatology, 2015Many group‐living animals actively defend a home range against neighboring groups. In many of these societies, males are the primary participants during group defense, while female participation ranges from seldom to frequent. Among howler monkeys (Alouattaspp.), loud calls (i.e., howling) are often used in the context of intergroup spacing as a form ...
