Thermal physiology of Amazonian lizards (Reptilia: Squamata)
Diele-Viegas, Luisa Maria; Vitt, Laurie Joseph; Sinervo, Barry R.; Colli, Guarino R.; Werneck, F. P.; Miles, Donald B.; Magnusson, William ErnestWe summarize thermal-biology data of 69 species of Amazonian lizards, including mode of thermoregulation and field-active body temperatures (Tb). We also provide new data on preferred temperatures (Tpref), voluntary and thermal-tolerance ranges, and thermal-performance curves (TPC’s) for 27 species from nine sites in the Brazilian Amazonia. We tested for phylogenetic signal and pairwise correlations among therm...
Aposematism increases acoustic diversification and speciation in poison frogs
Santos, Juan Carlos; Baquero, Margarita; Barrio-Amorós, César Luis; Coloma, Luis A.; Erdtmann, Luciana K.; Lima, Albertina PimentalMultimodal signals facilitate communication with conspecifics during courtship, but they can also alert eavesdropper predators. Hence, signallers face two pressures: enticing partners to mate and avoiding detection by enemies. Undefended organisms with limited escape abilities are expected to minimize predator recognition over mate attraction by limiting or modifying their signalling. Alternatively, organisms w...
