Jered Karr is a graduate student at UC Santa Cruz. He is working with Paul Koch. (Enough third person). I am interested in the effects that ecology and environment have had on evolution. My current research is looking at the ecology of herbivores in eastern Beringia. I am using stable isotopes of Oxygen, Nitrogen and Carbon to piece together the climatic conditions during the last ice ages in Eastern Beringia as experienced by herbivores.

Another project I have been working on is looking at the constraints on the evolution of the insects. I have been working on this project with Matthew Clapham.  The main focus is size constraints. We have been doing this with a comprehensive database based on published literature. We are currently in the process of importing our database into the Paleobiology Database.
