Curriculum Vitae 

Stephen Bovio

I graduated from Trinity University with a B.S. in Biology. As an undergraduate, I examined the social and mating system of the Northern Pygmy Mouse (Baiomys taylori) by monitoring a wild population using mark-recapture and radiotelemetry.

In 2016, I joined the Rosenthal laboratory. Today, my interests focus on mate choice and its evolutionary consequences. In the Xiphophorus genus, female swordtails undergo multiple inseminations from conspecific and heterospecific males and have the ability to store sperm for up to six months. However, the way in which X. birchmanni and X. malinche females handle sperm when inseminated with conspecific and heterospecific sperm remains unknown. Therefore, the aim of my research is to determine whether female sperm storage and fertilization is biased towards conspecific males when mated with members of both species. Specifically, I am interested in the way stored sperm genotypes represented in the female reproductive tract correlate with genotypes of fertilized embryos (i.e. sperm that actually sired offspring), and in turn, how mechanisms of cryptic female choice and sperm competition influence reproductive isolation barriers. I intend on investigating these questions through a series of insemination assays in which females have access to conspecific and heterospecific males. Afterwards, I will use paternity analysis to measure the proportion of offspring sired by conspecifics. In all, this approach should help to shed novel insight into barriers that either promote or prevent gene flow across populations.

Outside of lab you’ll find me playing Ultimate Frisbee, cooking, taking my dog on walks, and watching movies.
