Chromosome studies in Alouatta belzebul

American Journal of Primatology, 1987
AbstractThe chromosome constitution of Alouatta belzebul was studied with G‐, C‐, and silver staining. In ten specimens identified as Alouatta belzebul, the chromosome constitution of males (2n = 49) differed from that of females (2n = 50) owing to a Y‐autosome translocation.

Predation of Alouatta puruensis by Boa constrictor

Primates, 2013
Reports of successful predator attacks on primates are rare. Primates from all major radiations are particularly susceptible to raptors, carnivores, and snakes. Among New World primates, reports of snake predation are limited to medium- and small-bodied species.

Wild mixed groups of howler species (Alouatta caraya and Alouatta clamitans) and new evidence for their hybridization

Primates, 2007
Mixed species groups and hybridization are common among primates, yet these phenomena are rare and poorly understood for the genus Alouatta. In this study, we describe the composition of howler groups in a sympatric area of Alouatta caraya and Alouatta clamitans and provide new evidence for the occurrence of interspecific hybridization.

Conservation Biology of the Genus Alouatta

International Journal of Primatology, 1998
As assessed by the IUCN Mace–Lande system, seven (35%) of the 20 Alouatta species and subspecies with adequate data are classified as “threatened,” i.e., critically endangered, endangered, or vulnerable (Rylands et al., 1995). This percentage is much lower than the 75 to 100% threatened taxa for the other large-bodied genera: Ateles, Lagothrix, and ...
