Prof. Blouin-Demers has spent most of his research efforts attempting to explain two major patterns: 1) why does animal density vary spatially, and 2) why are several animals polymorphic. He has mostly used reptiles as study organisms, but has worked on fish, amphibians, birds, and mammals. Because reptiles are, proportionally, the most threatened vertebrate group in Canada, prof. Blouin-Demers also hopes to contribute to their conservation.
