“…On the other hand, location data are scarce from other hilly areas of the Atlantic Forest where the species might occur, particularly in the state of RJ. Some recent sightings of B. torquatus in the municipalities of Cachoeiras de Macacu, Nova Friburgo and Teresópolis (Boffy et al. 2010), for example, suggest that the species might have a broader distribution in RJ than is indicated by the available data.…”

ABSTRACTm am_188 35..54 1. The endemic maned sloth Bradypus torquatus is globally threatened due to deforestation, habitat fragmentation and isolation of populations. Despite increased interest in the species in recent years, information on its geographic distribution is limited and is derived mainly from a few museum species and from a survey based mostly on interviews carried out more than 20 years ago. Information on its habitat and altitudinal preferences is lacking. We therefore compile, update and review all occurrence records of this species using geographical information system (GIS) tools and produce a distribution map for the species. 2. Our compilation totalled 188 occurrence records, of which 130 (69%) were considered confirmed (museum specimens or individuals captured or seen in the field), most of which (62%) were restricted to the states of Bahia and central-south Espírito Santo (29%). The species occurs predominantly in ombrophilous forest (80%), from sea level to 1290m, but mainly (79%) below 200m altitude. 3. We used GIS techniques and the alpha shape algorithm to calculate the extent of occurrence of the species and compared the resulting map with distribution maps available in the literature. We found a great deal of variation in distribution area shape and an almost two-fold variation in distribution area size among sources. 4. We confirmed the existence of a main distribution gap between southern Bahia and northern Espírito Santo and discovered a second smaller gap between southern Espírito Santo and northern Rio de Janeiro. 5. We also confirmed that B. torquatus is sympatric with the common three-toed sloth Bradypus variegatus in a large part of the Atlantic forest and that the two species are syntopic in at least 11 locations.

“…Also, the known populations of maned sloth are in restricted and discontinuous regions in the states of Bahia, Espírito Santo, and Rio de Janeiro, separated by apparent distributional gaps between Mucuri River and Doce River in southern Bahia and northern Espírito Santo, and other one between southern Espírito Santo and northern Rio de Janeiro [20] , [21] , [28] . However, there are still a lot of unconfirmed records and gaps of knowledge about the species’ geographic range, mainly because it is a difficult animal to see in the wild due its behavior [29] , its cryptic nature [22] , [30] and misidentification.…”

The Distributional Ecology of the Maned Sloth: Environmental Influences on Its Distribution and Gaps in Knowledge

et al. 2014

The maned sloth Bradypus torquatus (Pilosa, Bradypodidae) is endemic to a small area in the Atlantic Forest of coastal Brazil. It has been listed as a threatened species because of its restricted geographic range, habitat loss and fragmentation, and declining populations. The major objectives of this study were to estimate its potential geographic distribution, the climatic conditions across its distributional range, and to identify suitable areas and potential species strongholds. We developed a model of habitat suitability for the maned sloth using two methods, Maxent and Mahalanobis Distance, based on 42 occurrence points. We evaluated environmental variable importance and the predictive ability of the generated distribution models. Our results suggest that the species distribution could be strongly influenced by environmental factors, mainly temperature seasonality. The modeled distribution of the maned sloth included known areas of occurrence in the Atlantic Forest (Sergipe, Bahia, Espírito Santo, and Rio de Janeiro), but did not match the observed distributional gaps in northern Rio de Janeiro, northern Espírito Santo or southern Bahia. Rather, the model showed that these areas are climatically suitable for the maned sloth, and thus suggests that factors other than climate might be responsible for the absence of species. Suitable areas for maned sloth were located mainly in the mountainous region of central Rio de Janeiro throughout Espírito Santo and to the coastal region of southern Bahia. We indicate 17 stronghold areas and recommended survey areas for the maned sloth. In addition, we highlight specific areas for conservation, including the current network protected areas. Our results can be applied for novel surveys and discovery of unknown populations, and help the selection of priority areas for management and conservation planning, especially of rare and relatively cryptic species directed associated with forested habitats.

“…O registro dessas três espécies no segundo Plano de Manejo (Viveiros de Castro 2008) carecia de fotos ou depósito em museu para confirmação das espécies. No presente estudo também foi considerado o único registro existente de B. torquatus, que os autores afirmam ter sido realizado no interior do parque embora o ponto informado esteja localizado no seu entorno imediato (Boffy et al 2010).…”

Mamíferos Do Parque Nacional Da Serra Dos Órgãos: Atualização Da Lista De Espécies E Implicações Para a Conservação

A lista mais recente dos mamíferos que ocorrem no Parque Nacional da Serra dos Órgãos (PARNASO), com 79 registros, consta no seu segundo Plano de Manejo, publicado em 2008. O presente estudo teve como objetivo atualizar a lista de espécies de mamíferos do PARNASO, inserindo novos registros de espécies obtidos através de dados primários e revisão bibliográfica, considerando o período de 2002 a 2018. A revisão da lista do Plano de Manejo resultou em 75 registros válidos. Destes, três espécies foram consideradas localmente extintas (Panthera onca, Tayassu pecari e Tapirus terrestris) e não foram incluídas na presente lista. Desse modo, listamos aqui 100 espécies com registros recentes no PARNASO, o que representa um acréscimo de 28 espécies. As ordens com maior riqueza de espécies foram Rodentia e Chiroptera, com 32 e 23 espécies, respectivamente. Das espécies registradas, quatro são invasoras (Callithrix jacchus, C. penicillata, Rattus norvegicus e R. rattus), três são domésticas (Bos taurus, Canis familiaris e Felis catus), e 26 são ameaçadas de extinção. A análise da distribuição espacial da riqueza de espécies mostrou que apenas metade da área do parque possui ao menos um registro, e que os registros estão concentrados onde há infraestrutura para a pesquisa. A presença de espécies domésticas e invasoras, bem como as extinções locais detectadas, indicam a necessidade de ações de manejo no interior do parque. Esse grande acréscimo de espécies à lista evidencia o desenvolvimento da pesquisa com mamíferos nesta Unidade de Conservação e a necessidade de compilações mais frequentes dos resultados devido aos vários projetos em curso. O PARNASO tem papel de destaque na conservação de mamíferos ao ainda manter uma das maiores riquezas de espécies do Estado do Rio de Janeiro, e grande importância para a pesquisa, abrigando uma ampla gama de estudos e projetos de longa duração.
