Does heat tolerance actually predict animals' geographic thermal limits?

The "climate extremes hypothesis" is a major assumption of geographic studies of heat tolerance and climatic vulnerability. However, this assumption remains vastly untested across taxa, and multiple factors may contribute to uncoupling heat tolerance estimates and geographic limits. Our dataset includes 1000 entries of heat tolerance data and maximum temperatures for each species' known geographic limits (herea...

No. of bitstreams: 0 Previous issue date: 2021-10-01; The process of diversification can be studied at the phylogeographic level by attempting to identify the environmental features that promote and maintain population divergence. Here we investigate diversification in Rhinella granulosa, a Neotropical toad from northeastern Brazil, by testing a range of h...

No. of bitstreams: 0 Previous issue date: 1987-01-01; Karyotypic data are presented for Tropidurus hispidus (Sauria, Iguani-dae) collected at six different localities in Brazil. The specimens from all the populations share the same basic 2n = 36 karyotype characterized by 12 macrochromosomes and 24 microchromosomes. The X is an acrocentric microchromosome ...

A new species of Placosoma Tschudi, 1847, until now restricted to the Atlantic Forest areas of southeastern Brazil is described based on specimens obtained about 1700 km north to the current distribution of the genus. Placosoma limaverdorum spec. nov. is apparently endemic to three “brejos-de-altitude”, relictual forest mountains surrounded by dry Caatingas, in the State of Ceará, northeastern Brazil. It differ...
