Mimicking venomous snakes: untangling the history of deceptive coloration
If a mimicry system offers protection from predators, then why hasn't evolution eliminated the "failed mimics," such as ground snakes sporting color patterns that don't remotely resemble a coral snake? That's the puzzle that University of Michigan evolutionary biologist Alison Davis Rabosky has spent the last four years trying to solve.

Fluid-preserved Invertebrate Imaging Workshop a success!
This workshop, conducted by Mark O'Brien, focused on imaging techniques for fluid-preserved invertebrates and microscopic slides. The target audience included collections managers, curators, and directors in U.S. non-federal invertebrate collections with significant numbers of fluid- and microscopic-slide-preserved specimens. The primary goal was to prepare participants for imaging these difficult-to-record collection objects.

On the U-M Gateway: Living fossils? Actually, sturgeon are evolutionary speedsters
"Sturgeon are thought of as a living fossil group that has undergone relatively slow rates of anatomical change over time. But that's simply not true," said Professor Daniel Rabosky.
