Snake assemblage of Ilha de São Sebastião, southeastern Brazil: comparison to mainland

Abstract

MARQUES, O.A.V. 2008. Snake assemblage of Ilha de São Sebastião, southeastern Brazil: comparison to mainland. Biota Neotrop. 8(3): http://www.biotaneotropica.org.br/v8n3/ en/abstract?article+bn00608032008. Abstract:We provide a checklist of snake species from Ilha de São Sebastião (Ilhabela), the largest coastal island in Brazil located on the northern coast of São Paulo state. We also compare snake diversity (including richness and relative abundance of species) of Ilhabela and the nearest mainland municipality, São Sebastião. We obtained the data from the herpetological collections of the Instituto Butantan and Museu de Zoologia of Universidade de São Paulo, including records from 1939 to 2005. We recorded twenty snake species from Ilhabela (N = 376 individuals), and the dominant species was the viperid Bothrops jararaca with 55% of dominance. In São Sebastião we recorded 27 species (N = 625), and Bothrops jararaca was also the dominant species, but with 25% of dominance. Some common species seem to be more abundant in the mainland. Even considering the different number of individuals sampled between localities, rarefactions curves and richness estimations confirm that São Sebastião should present a higher number of species. The Chao 1 estimates 20 species (19 to 21 spp.) for Ilhabela, and 32 species (27 to 37 spp.) for São Sebastião. One of the most distinctive aspects of the snake fauna of Ilhabela is the occurrence of four species of the genus Dipsas (D. albifrons, D. alternans, D. neivai, and D. petersi). Throughout most of the coastal Atlantic Forest of São Paulo state only D. petersi is recorded. This is the first assessment of diversity of snakes in Ilha de São Sebastião and the municipality of São Sebastião. Thus, it is a contribution to the knowledge and conservation of the herpetofauna of the region and of the Atlantic Forest of southeastern Brazil.

Herpetofauna dos remanescentes de Mata Atlântica da região de Tapiraí e Piedade, SP, sudeste do Brasil

“…1, Jan./Mar. 2009 Centeno et al, 2008). Em comparação com os anfíbios, os répteis do Planalto Atlântico e interior do estado são ainda menos conhecidos: Serra do Japi , Parque Estadual Intervales (Sazima 2001), Caucaia do Alto (Dixo & Metzger, no prelo) e Reserva Florestal do Morro Grande (Dixo & Verdade 2006), ressaltando a necessidade de trabalhos mais completos para a caracterização da fauna encontrada na região.…”

Composition and natural history of the snakes from the Parque Estadual da Serra do Papagaio, southern Minas Gerais, Serra da Mantiqueira, Brazil

“…Specimens identified as Thamnodynastes sp. by Salles and Silva-Soares (2010) belong to Thamnodynastesnattereri (Mikan, 1820) (Franco and Ferreira 2002), as well as the specimens cited as Thamnodynastescf.nattereri by Marques and Sazima (2004), Centeno et al (2008), Pontes et al (2008), Bertoluci et al (2009), Hartmann et al (2009b), Silveira et al (2010), Vrcibradic et al (2011), Moura et al (2012) and Citeli et al (2016). Specimens considered as Chironiusflavolineatus (Jan, 1863) by Condez et al (2009), São Pedro and Pires (2009), Forlani et al (2010) and Silveira et al (2010) were described as Chironiusbrazili Hamdan & Fernandes, 2015 (Hamdan and Fernandes 2015).…”

“…by Moura et al (2012) was considered Epicratescenchria (Linnaeus, 1758) according to the own comments on Moura et al (2012). Specimens addressed as Dipsasneivai Amaral, 1926 by Centeno et al (2008) correspond to Dipsasvariegata (Duméril, Bibron & Duméril, 1854) (Harvey and Embert 2008). The specimens cited as Chironiuscf.quadricarinatus and Liophiscf.almadensis by Bertoluci et al (2009) were considered Chironiusquadricarinatus (Boie, 1827) and Erythrolamprusalmadensis (Wagler, 1824), respectively.…”

Seasonal, daily activity, and habitat use by three sympatric pit vipers (Serpentes, Viperidae) from southern Brazil

“…Most radiation occurred within the subfamily Crotalinae, and in South America representatives can be found in all ecosystems . In Brazil, the members of this subfamily are generally abundant in inventories and studies of snake assemblages (Martins and Oliveira 1998, Santos et al 2005, Zanella and Cechin 2006, Pontes et al 2008, Hartmann et al 2009a, b, Guizoni-Jr et al 2009, Centeno et al 2008, with exceptions (e.g., Winck et al 2007, Martins et al 2012. However, studies are still incipient in remnants of Atlantic Forest in southern Brazil, where Bothrops diporus (Cope 1862), Bothrops jararaca (Wied 1824), and Bothrops jararacussu Lacerda, 1884 occur in sympatry.…”
