Ruth Rivkin is a 4th year PhD Candidate in the EvoEco Lab at the University of Toronto Mississauga. She studies the evolutionary ecology of plant mating systems and plant-pollinator interactions in cities from experimental and natural history perspectives. Currently, she is working on three projects. First, she has collaboratively built a dataset of all research on non-adaptive urban evolution, to review and generate predictions on how gene flow and genetic drift vary across cities and taxa. Second, she aims to experimentally determine how plant fitness varies with degree of urbanization. Finally, she is deciphering demographic, mating system, and population genomic variation within and between cities in a native Ontario wildflower.
