This proposal is an extension of previous work aimed at understanding the effects of reproductive biology on patterns of life history evolution in a colonial marine tunicate, Botryllus schlosseri. The project will test five hypotheses about factors that may determine male reproductive success in natural spawns of this colonial invertebrate. The five hypotheses specifically aim to explore the effects of timing of sperm release, relatedness of mates, population density, and allocation to male function on fertilization success in field and experimental populations of Botryllus.
Previous work has shown that there is a narrow temporal window in which fertilization can result …
