Brock University graduate students embraced the Halloween spirit by using their pumpkin decorating skills to creatively illustrate their research. On Thursday, Oct. 26, students representing labs within the Faculty of Mathematics and Science participated in a pumpkin carving contest organized by Graduate Mathematics and Science Students (GRAMSS). Gurprince Atlas (left) a master's student in Psychology, and Alex Popesco, a master's student in Biological Sciences, created a jack-o-lantern illustrating Popesco’s research, which focuses on urbanization-driven changes of social anti-predator behaviour in American crows. Popesco, who is a member of Assistant Professor of Biological Sciences Kiyoko Gotanda’s research group, said his research debunks the myth that crows significantly contribute to the decline of bird populations through nest predation. Atlas and Popesco's pumpkin features two crows invading a robin’s nest filled with blue eggs made from lab gloves.
