Comparative Phylogeography Of Glassfrogs (Vitreorama) Endemic To The Brazilian Altantic Rainforest, Zoe Spanos

Dissertations and Theses

The Brazilian Atlantic Forest harbors one of the most diverse faunas of the world, including 2-3% of all known vertebrate species. Understanding the role of both climate and landscape in shaping current biodiversity patterns has been the focus of many recent phylogeographic studies. Here I explore multiple factors thought to have impacted the generation of local diversity in the Brazilian Atlantic Forest (AF) using two montane, stream-associated species of glassfrogs – V. eurygnatha and V. uranoscopa. I integrate species distribution modeling, path analysis, and molecular data to test the role of climatic stability, rivers, mountain chains, and geographic distance in …
