Non-volant mammals from Núcleo Santa Virgínia, Serra do Mar State Park, São Paulo, Brazil

Abstract

This study presents data on the composition and species richness of non-flying mammals in the northern part of the Parque Estadual da Serra do Mar, called Nú cleo Santa Virgínia (NSV -around 17000 hectares of Atlantic Forest), Sã o Paulo state, southeastern Brazil. The species list was based on ca. 660 km of line-transects, 25512 hours of cameras traps, 7740 trap.nights for small mammals, and 394 track-station.days, as well as occasional records and registers from local people (period 2002 to 2009 IntroductionThe Atlantic Forest, one of the most threatened biomes on the planet, contains 298 species of mammals, 90 of which are endemic (Paglia et al. 2012) and 14% threatened under extinction (Chiarello et al. 2008). With approximately 60% of the Brazilian population living in these areas (Pinto et al. 2006), the Atlantic Forest remains under pressure due to urbanization, increasing road network, construction of pipelines, uncontrolled growth of ecotourism (SMA 1999, MMA 2002, hunting and extraction of plant resources (Galetti & Chivers 1995, Dean 1996, Galetti & Fernandez 1998, Cullen et al. 2000. As a consequence, currently less than 11% (16,377,472 ha) of its original vegetation remains, and of these, only 13.8% are legally protected (Ribeiro et al. 2009).Although threatened and with an urgent need for scientific surveys, biodiversity in few localities of this biome have been investigated, and most often, few groups were targeted for study. In the case of mammals, this scenario is further complicated. Rare are the times in which the group is inventoried as a whole (e.g. Voss & Emmons, 1996), studies with partial sampling being more common. These ''partial'' studies lacks some methods and/or last just a short time. Mammal surveys tend to adopt the following division, based on www.scielo.br/bn http://dx

Re-discovering jaguar in remaining coastal Atlantic Forest in southeastern Brazil by non-invasive DNA analysis

“…These results are quite surprising and indicate that three individuals are at least temporarily using the SVU (Figure 2). The presence of this large carnivore highlights the importance of this conservation unit and that it maintains a high degree of habitat integrity, with its high species diversity (Ripple et al 2014, Rocha-Mendes et al 2015. Moreover, this fact likely ensures more stability to this ecosystem since the jaguar has an important role on a top-to-down population control (Terborgh et al 2001).…”

“…Because of its large size, the park was divided into ten administrative units, which include the Santa Virginia unit, where the study was conducted and which is recognized for its high biodiversity (Galetti et al 2009, Rocha-Mendes et al 2015. However, although the jaguar is believed to occur there (Rocha-Mendes et al 2015), its presence has not been confirmed, after extensive camera trapping efforts between the years 2008-2011.…”

“…However, although the jaguar is believed to occur there (Rocha-Mendes et al 2015), its presence has not been confirmed, after extensive camera trapping efforts between the years 2008-2011. In a recent camera trapping-based large scale survey on the jaguar occurrence, no individual was accounted in SVU (Paviolo et al 2016).…”

Trophic Niche Differentiation in Rodents and Marsupials Revealed by Stable Isotopes

“…Although similar in many ecological aspects, these three sites differ in the abundance of large mammals that may interfere in the diet of small mammals [ 37 ]. At least 25 species, nine marsupials and 16 small rodents, compose the small mammal communities of this region [ 38 , 39 ].…”

Mamíferos Do Parque Nacional Do Iguaçu

“…Para esse fim, o armadilhamento fotográfico (camera-trap) foi utilizado como método principal, e de forma complementar, foram utilizados dados de visualizações ocasionais e registros indiretos (e.g., pegadas, fezes, tocas e vocalizações). A combinação desses métodos resulta em um melhor resultado no registro da riqueza de espécies (Brocardo et al 2013, Rocha-Mendes et al 2015 Preto e a garagem de uma concessionária localizada em frente a essa base, para captura de pequenos roedores exóticos (coordenadas: 25°37'40,13" S, 54°27'46,64" O; cerca de 2 km da área amostrada pelas transecções lineares). Na FOM, durante pesquisa sobre interação da fauna de pequenos mamíferos com sementes de Araucaria angustifolia foram estabelecidas seis grades amostrais, monitoradas no período de maio a agosto de 2012 e de outubro de 2012 a janeiro de 2013 (Ferracioli 2013).…”
