Mesmo após a devastação de grande parte das suas matas, o Estado do Rio de Janeiro ainda abriga uma grande riqueza de mamíferos terrestres. Contudo, informações sobre abundância e distribuição da mastofauna do Estado ainda são escassas. Este estudo tem como objetivo inventariar os mamíferos do Parque Estadual do Desengano, localizado na região norte do Estado do Rio de Janeiro, uma das regiões menos amostradas e mais alteradas do Estado. O inventário foi realizado utilizando armadilhas do tipo Sherman e Tomahawk, e armadilhas de queda para os pequenos mamíferos não-voadores, redes de neblina para os morcegos, armadilhas fotográficas, avistamentos e relatos de moradores e funcionários do Parque para os mamíferos de maior porte. Nós registramos 56 espécies de mamíferos, das quais 15 constam na lista da fauna ameaçada de extinção do Estado do Rio de Janeiro e 10 na lista da fauna brasileira ameaçada de extinção, incluindo Brachyteles arachnoides. As espécies mais abundantes foram o morcego Sturnira lilium e o roedor Akodon serrensis. Além disso, Thaptomys nigrita, roedor normalmente pouco capturado no Estado, foi relativamente abundante no Parque Estadual do Desengano. Nossos resultados indicam que o Parque abriga 33,7% das espécies de mamíferos com ocorrência conhecida para o Estado, destacando a importância da área para a conservação da fauna do Rio de Janeiro.
The Atlantic Forest in the state of Rio de Janeiro is extremely fragmented and reduced in its original extension. Although there are a great number of studies related to the biome, few lists are available for this region. The present study seeks to get information on the mammals of a remnant forest in Serra da Concórdia, an area from which no information is currently available. The rapid mammal's survey was accomplished by use of pitfalls, live traps, transects, mist nets, and camera traps. We recorded 37 terrestrial species that represent 22.3 % of Rio de Janeiro state mammal species. Among the recorded species, six are endemic of the Atlantic Forest, one is endemic of the state, and eight are in the state list of threatened or presumably threatened species. The area presents great mammal richness and an increasing effort will probably reveal the presence of additional species.
The Atlantic Forest is recognized as a global hotspot for having one of the highest rates of endemism and biodiversity. Its portion in the state of Rio de Janeiro is extremely fragmented and reduced. The present study seeks to get information on the non-volant mammals of RPPN Rio das Pedras in municipality of Mangaratiba, state of Rio de Janeiro. The rapid mammal's survey was accomplished by the use of pitfalls, live traps, transects and camera traps. We recorded 23 non-volant species that represent 13
The Atlantic Forest is considered a hotspot due to its current state of vast degradation and high indexes of biodiversity. This biome has been degraded through the years by processes resulting from the Brazilian socioeconomic model of development. The seasonal semi-deciduous Atlantic Forest is a poorly studied phytophysiognomy specially degraded by human activities in the state of Rio de Janeiro. In the present study we report the results of a rapid mammalian inventory conducted in the municipality of Cambuci, in a fragment of seasonal semi-deciduous forest. We used live traps and pitfall traps to capture non-volant small mammals, and mist-nets of different lengths to collect bats. To sample medium and large-sized mammals we used camera traps. We recorded 27 mammal species in the region, of which 16 are volant mammals. We emphasize the distribution extension of Trinomys setosus in 150 km (that enabled its insertion in the species list of Rio de Janeiro) and the capture of Lonchophylla peracchii, a recently described species apparently restricted to Atlantic Forest. Both facts show the importance of the fragment for the region biodiversity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
