Environmental sympatry through time: spatio-temporal distribution and conservation status of two sympatric anuran species (Leptodactylidae) in South America

Rev. biol. trop; 72 (1), 2024
Abstract Introduction: Leptodactylus latinasus and Physalaemus cuqui are sympatric anuran species with similar environmental requirements and contrasting reproductive modes. Climatic configuration determines distribution patterns and promotes sympatry of environmental niches, but specificity/selectivity...

Identification of the taxonomic status of Scinax nebulosus and Scinax constrictus (Scinaxinae, Anura) based on molecular markers

Braz. j. biol; 81 (4), 2021
Abstract The validation of many anuran species is based on a strictly descriptive, morphological analysis of a small number of specimens with a limited geographic distribution. The Scinax Wagler, 1830 genus is a controversial group with many doubtful taxa and taxonomic uncertainties, due a high number of...

A summary of reptile and anuran amphibian species from Brazilian sandy coastal plains: 31 years of sampling efforts of the "Laboratório de Ecologia de Vertebrados, Universidade do Estado do Rio de Janeiro"

Braz. j. biol; 81 (4), 2021
Abstract Although currently there is already a set of studies regarding ecological aspects of some particular reptile and amphibian species living in Brazilian sandy coastal plains (including the so-called "restinga" and "campo nativo" habitats), there is comparatively few information on the species comp...

Amphibians in a transition region between the Cerrado and the Atlantic Forest, west-central region of the state of São Paulo, Brazil

Studies of the diversity and natural history of amphibians are extremely important and contribute with the knowledge about the patterns of geographical distribution and biology of the species, outlining the factors that influence this distribution, and contributing to the development of conservation proj...
