Abstract We investigated the social relationships among adult females in two multimale-multifemale groups of black howler monkeys Alouatta pigra during a 14-month study in Palenque National Park, Mexico. Based on over 900 focal hours and over 5400 scan samples recording neighboring group members, we found that females very rarely engaged in agonistic interactions and no dominance hierarchy could be discerned. Relationships among resident females were primarily affiliative, but females of one study group spent a higher proportion of time in close proximity and engaged in affiliative interactions with one another at higher rates than females in the other study group. The strength of female relationships increased with the birth of an infant. Although no females immigrated during the study period, the temporary association of three extragroup females with our study groups implies that the social system of black howler monkeys is more dynamic than previously suggested. These findings suggest that female black howler monkeys behave more similarly to female red howler monkeys A. seniculus than to female mantled howler monkeys A. palliata.

Óbitos por infecções causadas por protozoários intestinais são indesejáveis para programas de manejo de fauna, exigidos no âmbito do licenciamento ambiental e que demandam a captura e quarentena de primatas não humanos. Exames coproparasitológicos, necroscópicos, microbiológicos e moleculares foram utilizados para a confirmação do diagnóstico de uma severa enterite necrótica que levou a óbito três fêmeas e dois machos de Alouatta (A.) caraya capturados e mantidos em quarentena prévia à translocação. Exames coproparasitológicos revelaram a presença de cistos de Entamoeba (E.) histolytica/dispar (5/5), Entamoeba (E.) coli (5/5) e Giardia (G.) duodenalis (1/5). A avaliação necroscópica revelou áreas de necrose multifocal severa na mucosa e submucosa intestinal. A análise microscópica revelou a presença de estruturas morfologicamente compatíveis com trofozoítos do gênero Entamoeba spp. em todos os indivíduos examinados. Além disso, G. duodenalis (1/5) foi demonstrada pela técnica de Nested PCR. Sugere-se que quando for necessário o cativeiro temporário de primatas, deverão ser adotados protocolos de manejo adequados buscando a destinação imediata dos animais, de moto a mitigar os efeitos negativos do estresse e reduzir o risco da ocorrência de infecções.
