Phylogeny and Ecology Determine Morphological Structure in a Snake Assemblage in the Central Brazilian Cerrado

It is concluded that phylogeny is the most important factor determining structure of this Neotropical assemblage of snakes and a strong ecological component characterizes a peculiar snake fauna in the Cerrado of Distrito Federal, Brazil.

Ecology of the Gecko Gymnodactylus geckoides amarali in a Neotropical Savanna

It is suggested that large female size is likely a plesiomorphic character of gekkonids and that large head size in males results from sexual selection theory.

Geographical Variation in the Ecology of Populations of Some Brazilian Species of Cnemidophorus (Squamata, Teiidae)

According to the hypothesis that environmental conditions exert an important influence upon life-history parameters, populations under seasonal climates concentrate their reproductive effort during the short reproductive season, producing larger clutches, whereas those under more stable or unpredictable climates reproduce continuously, yielding smaller clutches.

Life-History Patterns of Lizards of the World

A large life-history data set (674 lizard populations, representing 297 species from 263 sites globally) is compiled to test a number of hypotheses regarding the evolution of life- history traits in lizards, finding significant phylogenetic signal in most life- histories traits and variation in trait values explained by clade membership is unevenly distributed.

Acoustic ecology of an anuran assemblage in the arid Caatinga of northeastern Brazil

Investigation of relationships among 12 anurans that co-occur in temporary ponds in the Caatinga, Cabaceiras municipality, Paraíba state, Brazil suggests that the calling activity of the species is strongly influenced by rainfall, and the temporal partition appears to ensure coexistence.

Phylogeny and micro-habitats utilized by lizards determine the composition of their endoparasites in the semiarid Caatinga of Northeast Brazil

The objective of this study was to analyze the architecture of networks between lizards, their endoparasites, diet, and micro-habitat, aiming to understand which factors exert an influence on the composition of the species of parasites.
