Another year of fieldwork and observation has yielded a slew of captivating photos from LSA’s Department of Ecology and Evolutionary Biology. Every year, the department hosts a photo challenge in which snapshots taken by students, faculty, and staff during the past 12 months are submitted to a vote. The contest honors the memory of the department’s longtime “photographer at large,” David Bay, a staff member who passed away in 2009. This year’s photos include a receding glacier, a thorny lizard, and the world’s smallest living monkey. Scroll through the images below for an eyeful of the winners.
