The Systematic Status of the Black Howler Monkey, Alouatta Pigra Lawrence
Journal of Mammalogy, 1970An apparent case of sympatry between two supposed races of Alouatta pallida (Gray) was discovered near Macuspana, Tabasco, Mexico. Howler monkeys in the Tabascan series were easily separated into two distinct groups based on various characteristics of the cranium, dentition, and pelage.

Detection and prevalence of adenoviruses from free-ranging black howler monkeys (Alouatta pigra)
Virus Genes, 2018Adenoviruses are important pathogens known to infect vertebrate hosts, including a wide range of primates. Despite its importance, data on the diversity of these viruses in non-human primates living in their natural habitat remain scarce. In this study, we conducted a surveillance of adenoviral infection in wild black howler monkeys from two protected ...

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 ...

AbstractLittle is known about the population characteristics ofAlouatta pigraunder conditions of forest fragmentation–information that is important to understanding its tolerance to habitat loss. In this work we present data on forest loss and on troop size, age, and sex composition for a population of black howler monkeys existing in the fragmented ...

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 ...
