EEB Seminar – 26 November

This week EEB welcomes Queen’s Alumna (BSc, MSc) and current Queen’s Post-Doc, Dr. Sarah Yakimowski, who will present:

Ecology and evolutionary genetics of gender polymorphisms

Plants exhibit a variety of reproductive strategies, providing exciting opportunities to study the evolution of gender. The clonal aquatic plant Sagittaria latifolia is widespread in wetlands of North America, where it exhibits three gender morphs – female, hermaphrodite and male. These gender morphs coexist within populations in different combinations to form diverse sexual systems. This talk will explore how, and why, sex ratios vary geographically and test alternative origins for the coexistence of all three sex phenotypes within this single species.


Sarah completed her BSc and MSc at Queen’s Biology and has recently returned as a postdoc. The work in this talk was completed for her PhD at the University of Toronto, which was followed by a postdoc at UBC to study the role of hybridization on speciation.


The EEB Seminars run weekly, on Thursdays, in the EEB Lounge of the  BioSciences Complex, Room 4338, from 12:30-1:30pm. Light refreshments are served starting at 12:15.
