Suzanne Alonzo is professor at the University of California, Santa Cruz. Her research focuses on how social or behavioural interactions affect evolutionary dynamics. She uses phenotypic and genetic modelling approaches to examine how interactions within and between the sexes affect the evolution and expression of reproductive behaviours. Her experimental systems include the ocellated wrasse in Corsica, the tessellated darter in Connecticut, and mosquitofish in California.
John Fitzpatrick is professor at the Department of Zoology at Stockholm University. Combining experimental work on tropical freshwater fishes and phylogenetic comparative approaches, he studies reproductive behaviours to understand how sexual selection affects evolution. He is particularly interested in pre-mating competition, mate choice (both before and after mating), sperm competition, trade-offs among sexually selected traits, and co-evolutionary dynamics between the sexes.
Susanna Pla holds a Ph.D. in Biology from the Autonoma University of Barcelona and completed her doctoral studies at the Institute of Marine Sciences (ICM) in Barcelona, a centre of the Spanish National Research Council (CSIC). Her research began with the study of the incidence, distribution, and environmental associations of sexual patterns in fish, eventually expanding into a broader investigation of the evolutionary history of sexual systems in fish, using comparative methods to understand the origin and evolutionary trajectories of hermaphroditism. She currently combines her work as a high school biology teacher at several schools in Barcelona, promoting science among adolescents, with collaboration in scientific research projects.
