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.

Abstract The black-and-gold howler monkey (Alouatta caraya) is widely distributed in Brazil, Bolivia, Paraguay, and northeastern Argentina. Despite this wide distribution, it is locally threatened in some parts of its southern range by forest loss and fragmentation, and yellow fever outbreaks. We present 14 new localities of A. caraya occurrence in the Pampa biome of southern Brazil, extending its range southwards by approximately 100 km.

AbstractLoud calls can be expected to play an important role in the lives of howler monkeys, given the specialised anatomy of howler vocal apparatus and the time and energy invested in calling. Here we present observational and experimental data aimed at understanding the function(s) of the roars of black howler monkeys (Alouatta caraya). Most roars were given spontaneously, especially around dawn, although inter-group encounters and extreme weather events triggered calling. Roars were given throughout the home range, but not uniformly; variations in calling frequency with location were not well predicted by frequency of use, and calling was not more frequent at borders. Predator presence was neither necessary nor sufficient to stimulate calling. We experimentally played back loud calls from stranger groups, either inside the home range of the study group, simulating invasions, or in border areas. In response to simulated invasions, the alpha male roared more frequently than expected, usually in the vicinity of the playback site, moved off sooner and travelled to or near to the playback site. When playback was in border areas, the alpha male roared infrequently and significantly later, and did not travel towards the playback site. These results are not consistent with the hypotheses that roaring functions in predation deterrence and/or mate defence. Instead, they suggest that roaring allows regulation of the space use, by means of regular advertisement of occupancy but not by mutual avoidance or boundary defence. We believe that roars also provide a mechanism for reinforcing occupancy during encounters, and may sometimes serve to settle disputes without chases and fights.
