Lythrum salicaria (purple loosestrife) is a major invasive species in Ontario. When forming new colonies, individuals of purple loosestrife may mate with themselves or close relatives out of necessity. This may induce a reduction of offspring fitness through inbreeding depression. In this project, we are quantifying the impact of inbreeding depression in this species in natural conditions. This work will attempt to quantify how the benefits of mating with close relatives are offset by inbreeding depression in this species.
