“…Snakes from these genera seem to be uncommon and rare in nature even when compared to other pseudoboini such as Oxyrho-pus guibei (Pizzatto and Marques 2002). Despite the generalist diet (Amaral 1978, Vitt and Vangilder 1983, Pinto and Lema 2002, Teixeira and Vrcibradic 2003 and continuous reproduction, most species (at least those occurring in warmer areas) exhibit a low fecundity, in terms of relative clutch size and reproductive frequency, when compared to Oxyrhopus guibei. Low clutch size is unexpected in large species such as Boiruna maculata, Clelia plumbea and Clelia clelia.…”

Body size, reproductive biology and abundance of the rare pseudoboini snakes genera Clelia and Boiruna (Serpentes, Colubridae) in Brazil. Pseudoboini snakes of the genera Clelia and Boiruna are apparently rare in nature and certainly rare in collections. This work presents data on body size, reproduction and abundance of five Brazilian species of these genera, in the largest collection of snakes in Latin America, the Instituto Butantan. Despite scarcity of data, follicular cycle seems to be continuous in most species, except Clelia rustica, which occurs in highlands. Females are larger than males in all species, and fecundity is low when compared to other pseudoboini. Abundance is very low for all species even considering 100 years of collecting, and it is decreasing in recent decades when compared to other snakes (Bothrops jararaca, Oxyrhopus guibei, O. clathratus, Philodryas patagoniensis, Sibynomorphus mikanii, and Spilotes pullatus). The studied species present at least five traits of commonly threatened species and require more attention in researches and conservation policies.

“…The diel activity is unknown, but it is probably nocturnal like other pseudoboines (Marques 1998). Like other species related to the genus Clelia, it probably feeds on lizards, snakes, and mammals (Vanzolini et al 1980, Marques et al 2001, Pinto & Lema 2002. One preserved specimen had a snake in the stomach (L. Pizzatto, pers.…”

Composition and natural history of a Cerrado snake assemblage at Itirapina, São Paulo state, southeastern Brazil

Abstract:Neotropical snake assemblages present high species richness and complex structures. The Cerrado is the second largest biome in Brazil, and was included among the 25 World's biodiversity hotspots. In southeastern Brazil, the remnant Cerrado areas have suffered intense destruction, and presently less than 2% of Cerrado natural vegetation remain in São Paulo state. Virtually no detailed study on Cerrado snakes was carried out in this region. The Itirapina region has one of the last well preserved remnants of open cerrado in São Paulo state. Our purpose in this work was the study of natural history and composition of the Cerrado snakes of Itirapina region. We performed an extensive field sampling combining six sampling methods in Estação Ecológica de Itirapina and disturbed Cerrado areas in its surroundings (municipalities of Itirapina and Brotas), during 101 trips throughout 43 months, between September 1998 and March 2002, corresponding to 446 days of field sampling. We also collected additional data from museum specimens housed in scientific collections. We present data on size, general abundance, habitat and macrohabitat use, daily and seasonal activity, feeding, reproduction, and defense. We also compared the Itirapina snake assemblage with nine snake assemblages of Brazil, from Amazonia, Atlantic Forest, Cerrado, and other open habitats. We recorded a total of 36 snake species among 755 individuals found in the field and six records from scientific collections and literature, belonging to 25 genera and five families. The snake assemblage comparisons indicate that the Cerrado has its own identity regarding the snake composition. Although small (about 2,300 ha), the Estação Ecológica de Itirapina encompasses well preserved and representative Cerrado physiognomic forms, which harbors a rich and typical Cerrado snake fauna. The occurrence of some species only inside the reserve also indicates that the Estação Ecológica de Itirapina is of fundamental importance to the maintenance of Cerrado biodiversity.

“…The constriction and drowning in the water of large prey such as rodents were reported as feeding behaviours of H. gigas in captivity (Astort, 1984). Hydrodynastes was proposed as the sister group of the pseudoboini tribe (Vidal et al, 2000), that include Boiruna and Clelia, mainly ophiophagus snakes, that show also prey constriction as characteristic feeding behaviour (Zaher, 1996;Costa Pinto and Lema, 2002).…”
