Cari-Ann Hickerson, PhD

Researcher, Part-time Professor and Publications Secretary for the Society for the Study of Amphibians and Reptiles (SSAR)

Location: Dolan Science Center W244

Expertise: Behavioral Ecology, Evolution, Forest-Floor Food Webs, and Herpetology, with an emphasis on the role of territorial behavior in population and community structure.

Research Interests: I am interested in the role of territoriality in shaping food webs, and the evolution and maintenance of color polymorphism in Eastern Red-backed Salamanders, Plethodon cinereus. This species is a model organism used in the study of behavior, ecology, food-web dynamics, evolution, disease ecology, and conservation genetics. I serve as co-advisor (with Dr. Carl Anthony) to students in the Anthony/Hickerson lab. Our students use predatory invertebrates, and red-backed salamanders to understand the ecology and evolution of this broadly distributed and abundant species of salamander. Most recently our lab is investigating the function of biofluorescence in P. cinereus which is a new discovered and sexually dimorphic trait in this species!
