The Ecology of the Endangered Dusky Gopher Frog (Rana Sevosa) and a Common Congener, the Southern Leopard Frog (Rana Sphenocephala)
… (Rana sevosa) and a common (Rana sphenocephala) frog in changing habitats, to determine why these two species differ in their persistence. I include additional studies investigating the habitat requirements and behavior of R. sevosa. I found that habitat change in the form of canopy closure over …
