In frog species, typically male frogs call, while females stay silent. Dr. Johana Goyes-Vallejos shows that in the smooth guardian frog of Borneo (Limnonectes palavanensis) this is not the case and that female frogs call, too, producing spontaneous vocalizations to attract males. Dr. Goyes-Vallejos’ discovery that female frogs call suggests that L. palavanensis exhibits a reversal in calling behavior and possibly a sex-role-reversed mating system, which would be the first ever observed in a frog species.
This talk is part of the Young Scientist Seminars, a video series produced that features young scientists giving talks about their research and discoveries.
Johana Goyes Vallejos received her bachelor’s degree in Biology from Universidad del Valle, in Cali, Colombia. For her Ph.D., she joined the lab of Dr. Kentwood Wells in the Ecology and Evolutionary Biology Department at the University of Connecticut. Johana’s research interests include sexual selection and amphibian mating systems (frogs and toads), with a particular… Continue Reading
