James J Roper

PeerJ Editor, Author & Reviewer

Summary

As an ecologist, I am interested in population dynamics of terrestrial vertebrates. To understand these dynamics, I use a combination of field data (usually with birds) and simulations. I am particularly interested in life histories of tropical and subtropical birds.
