Robert Hegna is an Associate Professor in the Biology Department at the School of Liberal Arts and Sciences, having joined the institution in 2014. His research specializes in behavioral ecology, particularly predator-prey dynamics and anti-predator defense mechanisms like aposematism (warning signals). He employs field experiments and population genetics to study how defensive tactics influence population structures across diverse ecosystems ranging from tropical regions to the Arctic.
Education:
- PhD in Ecology and Evolutionary Biology, University of Jyvaskyla
- MS in Biological Sciences, Florida International University
- BS in Zoology, Olivet Nazarene University
Research Focus: Hegna investigates evolutionary adaptations in species like the wood tiger moth (Parasemia plantaginis), examining geographic variations in warning signals, thermal trade-offs in melanization, and genetic underpinnings of defensive traits. His work extends to herpetology (poison frogs, snakes) and scorpion biology.
Publications: His recent articles (2011-2016) predominantly explore aposematism, evolutionary trade-offs, and biogeographic patterns in arthropods and amphibians, with recurring themes of predator cognition, signal efficacy, and environmental adaptation across taxa.
