Levantamento e diagnóstico de populações de Callicebus nigrifrons no Parque Estadual do Rio Doce e seu entorno / Survey of populations of Callicebus nigrifrons in the Rio Doce State Parc and its surroundings

Callicebus nigrifrons is one of the seven primate species that occur in the Rio Doce State Parc (PERD), which is part of the Atlantic Rain Forest Biosphere Reserve. The present study aims raise populations of C. nigrifrons and diagnose their conservation status in PERD and environment.The survey was conducted in July 2018, through interviews with the local population and researchers (n=24) and active search with playback support and characterization of forest fragments (n=22), in three regions: the interior of the park, north and south surroundings.. The occurrence of the species was recorded in the three regions by direct observation, vocalization in response to playback and / or interviewees' reports. Most of the sampled areas presented as small fragments with low vegetation quality, surrounded by pastures or eucalyptus plantations, especially in the vicinity of PERD. Although it is a species with a certain flexibility to live in small fragments and disturbed, the isolation, reduction and degradation of the habitats in the long term, can impact the genetic variability and availability of resources and, consequently, the viability of the populations of C. nigrifrons in these places. Therefore, the protection, recovery and recomposition of the connectivity of forests are measures of great importance to promote the survival of the species in PERD and especially in its surroundings.

Primatology in southern Brazil: a transdisciplinary approach to the conservation of the brown-howler-monkey Alouatta guariba clamitans (Primates, Atelidae)

Human interventions in natural environments are the main cause of biodiversity loss worldwide. The situation is not different in southern Brazil, home of five primate species. Although some earlier studies exist, studies on the primates of this region began to be consistently carried out in the 1980s and have continued since then. In addition to important initiatives to study and protect the highly endangered Leontopithecus caissara Lorrini & Persson, 1990 and Brachyteles arachnoides E. Geoffroy, 1806, other species, including locally threatened ones, have been the focus of research, management, and protection initiatives. Since 1993, the urban monkeys program (PMU, Programa Macacos Urbanos) has surveyed the distribution and assessed threats to populations of Alouatta guariba clamitans (Cabrera, 1940) in Porto Alegre and vicinity. PMU has developed conservation strategies on four fronts: (1) scientific research on biology and ecology, providing basic knowledge to support all other activities of the group; (2) conservation education, which emphasizes educational presentations and long-term projects in schools near howler populations, based on the flagship species approach; (3) management, analyzing conflicts involving howlers and human communities, focusing on mitigating these problems and on appropriate relocation of injured or at-risk individuals; and finally, (4) Public Policies aimed at reducing and/or preventing the impact of urban expansion, contributing to create protected areas and to strengthen environmental laws. These different approaches have contributed to protect howler monkey populations over the short term, indicating that working collectively and acting on diversified and interrelated fronts are essential to achieve conservation goals. The synergistic results of these approaches and their relationship to the prospects for primatology in southern Brazil are presented in this review.

Intervenções humanas nos ambientes naturais são a principal causa da perda de biodiversidade global. Essa situação não é diferente no sul do Brasil, onde vivem cinco espécies nativas de primatas. Embora existam algumas pesquisas anteriores, estudos sobre primatas nessa região começaram a ser desenvolvidos consistentemente no início da década de 1980 e continuaram sendo produzidos desde então. Além de importante iniciativas para pesquisar e conservar as espécies altamente ameaçadas Leontopithecus caissara Lorrini & Persson, 1990 e Brachyteles arachnoides E. Geoffroy, 1806, outras espécies, incluindo algumas localmente ameaçadas, têm sido foco de pesquisas, manejo, e iniciativas de conservação. Desde 1993, o Programa Macacos Urbanos (PMU) tem pesquisado a distribuição e avaliado as ameaças às populações de Alouatta guariba clamitans (Cabrera, 1940) em Porto Alegre e arredores. O PMU tem desenvolvido estratégias de conservação em quatro frentes de trabalho: (1) pesquisa científica em biologia e ecologia, gerando conhecimento básico para apoiar as outras iniciativas do grupo; (2) educação para conservação, que enfatiza ações educativas e projetos de longo-prazo em escolas localizadas próximas às populações do bugio-ruivo, baseados na abordagem de espécie-bandeira; (3) manejo, analisando conflitos que envolvam bugios e comunidades humanas, focando na mitigação desses problemas e na apropriada destinação dos animais machucados ou em risco; e (4) a frente de trabalho de Políticas Públicas, que visa reduzir e/ou prevenir os impactos da expansão urbana, contribuindo para criar áreas protegidas e fortalecer a legislação ambiental. Estas diferentes abordagens têm contribuído para a conservação das populações do bugio-ruivo em curto prazo, indicando que trabalhos desenvolvidos coletivamente e a atuação em frentes de trabalho interrelacionadas e diversificadas pode ser essencial para atingir as metas de conservação. Os resultados sinergéticos dessas abordagens e sua relação com a primatologia na região sul do Brasil são apresentados neste trabalho.
