UC San Diego graduate student Dionne Mejia is currently residing at the Steele/Burnand Anza-Borrego Desert Research Center as she works on her master’s thesis studying the diversity, distribution and ecology of cactophilic rove beetles (family Staphylinidae) in the Sonoran Desert. Staphylinids colonize the necrotic tissue of rotting barrel cactus (Ferocactus cylindraceus). Dionne is working with Dr. Therese Markow and Dr. Maxi Richmond at UC San Diego.
