Natural History of Pseudoboine Snakes

Abstract

Even though natural history information is crucial for answering key ecological

First record of Siphlophis compressus (Daudin, 1803) (Serpentes, Dipsadidae) from the state of Roraima, Brazil

“…The voucher specimen is housed in the Museu de Zoologia da Universidade de São Paulo (MZUSP 22598). During the capture, the individual vibrated its tail as a defensive display, as previously reported by Fraga et al (2013) and Gaiarsa et al (2013).…”

“…Species of the genus utilize a wide diversity of habits. Siphlophis cervinus, for example, is active at night (Martins and Oliveira 1998) and is semi-arboreal (arboreal data: Martins and Oliveira 1998;terrestrial data: Dixon and Soini 1986), while, S. leucocephalus is terrestrial (Argôlo 2004) and diurnal (Alencar et al 2013, Gaiarsa et al 2013). …”

“…Siphlophis compressus is a semi-arboreal snake (Gaiarsa et al 2013), which can be found in trees and on the ground Oliveira 1998, Bernarde andAbe 2006). This species is specialized in capturing and ingesting lizards (Fraga et al 2013), but occasionally feeds on anurans, snakes, lizard eggs, and mammals (Sazima and Argôlo 1994, Martins and Oliveira 1998, Prudente et al 1998, Marques et al 2001, Alemu and Rowley 2008, Alencar et al 2013.…”

On the snake Siphlophis worontzowi (Prado, 1940): notes on its distribution, diet and morphological data

“…The few specimens mentioned in the literature were found in pastureland, primary or disturbed forests, usually climbing or resting on the vegetation generally at night (Bernarde and Abe 2006; Moravec et al 2009;Costa et al 2010). Its dietary preferences are also poorly known and Prudente et al (1998), Bernarde and Abe (2006) and Gaiarsa et al (2013) describe only four items: three lizard species (Iphisa elegans, Gonatodes humeralis and Hemidactylus mabouia) and a frog without identification.…”
