The two courses are organized around student research conducted as an entire class and as projects conducted in 3 - 4 person teams. The research topics for group projects are varied. Each student is part of a team that designs and conducts research projects in behavioral and physiological ecology of reptiles. Part of data analysis includes composition of posters summarizing the project. Please browse through excerpts of the posters for sense of the scope of past projects. Image:Phrynosoma
