The Rosenblum lab studies the processes that generate and impact biological diversity. We are particularly interested in both sides of the evolutionary speciation/extinction “coin” and in determining the mechanisms of rapid adaptation of animals to changing environments. We work across levels of biological organization (from genes to phenotypes to behaviors to community assemblages) and use a variety of methodologies (from genomics to field ecology). Topically, many of our projects focus on reptile and amphibians in the western US. Currently funded efforts in the lab focus on disease-related declines in amphibians and ecological speciation in lizards. However, we have a diversity of other projects and collaborations in evolutionary ecology, ecological genomics, and global change biology.
