Ecologia e história natural das serpentes de uma área de Caatinga no nordeste brasileiro

Abstract

We studied a snake assemblage from

Composition and Ecological Aspects of a Snake Assemblage on the Savanna Enclave of the Atlantic Forest of the Guaribas Biological Reserve in Northeastern Brazil

“…21-61 species;Carvalho and Nogueira, 1998;França et al, 2008;Sawaya et al, 2008;Araujo et al, 2010), but higher richness than areas in the Caatinga (ca. 13-22 species; Vitt and Vangilder, 1983;Costa, 2006;Mesquita et al, 2013). Moreover, these variations in number of species may be due to the differences in the size of areas, sampling effort, and habitat structure.…”

“…Pitfall traps are responsible for 81% of all individuals collected, a result rather unusual, given that pitfall traps are a sampling method that often have collected fewest snakes in other studies (Hartmann et al, 2009b;Rocha and Prudente, 2010;Rodrigues and Prudente, 2011;Mesquita et al, 2013). However, this sampling method is highly effective for capturing fossorial and cryptozoic snakes (Cechin and Martins, 2000).…”

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

“…The buckets were drilled in the bottom to avoid accumulation of rainwater. Inside each bucket, we also put foliage together with a styrofoam plate to serve as a refuge for the fallen animals (Mesquita et al 2013). The drift fence was buried 20 cm below the ground and held upright by wood stakes.…”

“…These features pose challenges to quantitative and comprehensive study of these populations. There have been several efforts to describe the ecology and natural history of snakes in Brazil (e.g., Amazon Forest: Cunha and Nascimento 1978, Martins and Oliveira 1998, Pantanal: Strüsmann and Sazima 1993, Cerrado: Nogueira 2001, Sawaya et al 2008, Caatinga: Mesquita et al 2013, Guedes et al 2014; Atlantic Forest: Marques 1998, Cicchi et al 2007, Centeno 2008, Cicchi et al 2009, Hartmann et al 2009a, b, Trevine et al 2014). Although these studies have advanced our understanding of snake fauna in various ecosystems, studies focusing on snake communities in high altitude areas and the Araucaria forests remain scarce.…”

Ecological diversity of a snake assemblage from the Atlantic Forest at the south coast of Paraíba, northeast Brazil

“…They also provide the groundwork for ecological studies and provide an outline for implementing conservation strategies (Greene 1994, Sutherland 1997). Since 1990, there has been an increase in surveys of Brazilian snakes, with information about richness and natural history published for different biomes, such as Amazonia (Martins and Oliveira 1998, Bernarde and Abe 2006), Southeast Atlantic Forest (Marques and Sazima 2004, Pontes et al 2009), Northeast Atlantic Forest (França et al 2012, Dias and Rocha 2014, Marques et al 2016, Roberto et al 2017), Caatinga (Vitt and Vangilder 1983, Mesquita et al 2013), Cerrado (França et al 2008, França and Braz 2013), Pantanal (Strussmann and Sazima 1993, Strüssmann et al 2011), and Pampas grasslands (Winck et al 2007). However, some sites and environments are still poorly known, such as coastal restingas and mangroves.…”
