In amphibians solar basking far from water sources is relatively uncommon since the highly permeable amphibian skin does not represent a significant barrier to the accompanying risk of losing water by evaporation. A South American frog, Bokermannohyla alvarengai (Bokermann 1956), however, spends a significant amount of the day exposed to full sun and(More)
We report 14 microsatellite loci for Bokermmanohyla saxicola, a frog species endemic of the Espinhaço mountain chain in southeastern Brazil. We used a sample of 53 individuals from a single locality to characterize these polymorphic loci. Number of alleles per locus ranged from 3 to 17, observed heterozygosity and expected heterozygosity ranged from 0.125(More)
Microhabitat use is an important component of anuran behavior in both the tadpole and the adult stages. It is potentially influenced by phylogeny and extant ecological factors acting as selective pressures, such as predation, competition, or physical habitat properties. We aimed to test whether patterns of microhabitat use vary among species, habitats and(More)
An animal’s vulnerability to predators can be influenced by its behavior, morphology, body size, coloration, habitat preferences, and palatability. We tested whether the coloration of Bokermannohyla saxicola and Scinax machadoi tadpoles affects their survival when exposed to local visually oriented predators at a site in southeastern Brazil. We tested three(More)
Amphibian population declines are widespread; the main causal factors are human related and include habitat fragmentation due to agriculture, mining, fires, and urban development. Brazil is the richest country in species of amphibians, and the Brazilian regions with the greatest amphibian diversity are experiencing relatively high rates of habitat(More)
