Variation in the diet of the lizard Tropidurus torquatus along its coastal range in Brazil Biota Neotropica
Siqueira,Carla Costa; Kiefer,Mara Cíntia; Sluys,Monique Van; Rocha,Carlos Frederico Duarte.
The diet composition of lizards of a given species may vary among different populations. The feeding ecology of the tropidurid lizard Tropidurus torquatus was studied in 10 coastal areas in Brazil in order to detect to what extent the diet varies along its geographic range. A non-metric multidimensional scaling technique revealed three groups of localities according to the diet composition: one characterized by a relatively high consumption of Isoptera, one characterized by a relatively high proportion of plant matter, and one in which there was a great importance of Formicidae. We found a weak pattern of latitudinal differences in restingas regarding the general consumption of items by T. torquatus, probably because this is a generalist and opportunistic...

Herpetofauna of the Reserva Ecológica de Guapiaçu (REGUA) and its surrounding areas, in the state of Rio de Janeiro, Brazil Biota Neotropica
Almeida-Gomes,Mauricio; Siqueira,Carla Costa; Borges-Júnior,Vitor Nelson Teixeira; Vrcibradic,Davor; Ardenghi Fusinatto,Luciana; Frederico Duarte Rocha,Carlos.
Species inventories are useful tools to improve conservation strategies, especially in highly threatened biomes such as the Brazilian Atlantic Forest. Here we present a species list of amphibians and reptiles for the Reserva Ecológica de Guapiaçu (REGUA), a forest reserve located in the central portion of Rio de Janeiro state, Brazil. The list results from an extensive sampling effort that lasted ten years. A total of 73 amphibian (of which ten are endemic to the state) and 37 reptile species was recorded from the area. Five amphibian species are presently categorized by the IUCN as “data-deficient”, two as “near threatened” and one as “endangered”, whereas one reptile species is categorized as “vulnerable”. Our results showed that REGUA harbors about...
