Competition, guild structure and evolution in the carnivora

PI(s): Julie A Meachen
Start Date: 1-Aug-2009
End Date: 31-Jul-2012

I am examining how mammalian carnivores differentiate their diets and how they compete for resources within carnivore guilds. I will be examining both living guilds from all over the world and extinct guilds from the Pleistocene and Pliocene of North America. I will be looking at carnivore skeletal morphology to see if there is a shift in form or body size depending upon what other carnivore species are present in the guild. This data can ultimately be used to predict what will happen to the world's remaining carnivore species as other carnivore species in their guild become extinct.
