The evolution of parental care diversity in Amphibians

Dr Isabella Capellini

Our Biosciences Seminar Series resumes for the 2020 winter term with a talk by Dr Isabella Capellini from the School of Biological Sciences at Queen’s University Belfast, UKIsabella is an evolutionary ecologist, interested in the evolution of reproductive strategies, biological invasions, the ecology and evolution of sleep, and in general eco-evolutionary life history studies,  taking a comparative approach.


Abstract
Once evolved, parental care plays a key role in promoting social evolution, cooperation and conflict within the families, and alters the trajectory of life history evolution. Parental care is also extremely diverse across species, ranging from simple behaviour like attendance of the eggs to complex adaptation like food provisioning, lactation and viviparity. Most studies on parental care focus on one or few care forms, or reduce diversity to a simple presence/absence condition. Thus, we still do not know how diversity itself evolves, what the drivers of its evolution are, and whether all forms of care equally affect life history evolution. Amphibians offer the opportunity to address these questions being one of the most diverse taxon in reproductive, life history, and parental care strategies. By explicitly considering diversity and using phylogenetic comparative methods, we find support for some of the long standing hypotheses on the evolution of parental care, but also reveal a much more complex and unexpected picture on how and why care forms evolve, and what consequence different care forms have for the evolution of egg and clutch size.
