Using Conservation Genetics To Inform Reintroduction Of The Endangered Mottled Duskywing (Erynnis Martialis), Shayla Kroeze
Using Conservation Genetics To Inform Reintroduction Of The Endangered Mottled Duskywing (Erynnis Martialis), Shayla Kroeze
Electronic Thesis and Dissertation Repository
Habitat loss and climate change have caused declines in species diversity and abundance globally, including in butterflies which are important components of many ecosystems. Reintroductions are increasingly used to reverse diversity loss but are most effective when informed using genetics. I developed 24 microsatellites and characterized genetic structure and diversity of the endangered Mottled Duskywing (Erynnis martialis) in Ontario and neighbouring provinces and states. These were used to inform a planned reintroduction in Ontario. Populations had moderate levels of genetic diversity, however all but the largest populations may be subject to appreciable levels of genetic drift. Populations more …

Population Genetic Structure In The Pitcher Plant Flesh Fly Fletcherimyia Fletcheri, John R. O'Leary
Electronic Thesis and Dissertation Repository
The study of population genetic structure in the pitcher plant flesh fly, Fletcherimyia fletcheri, is an important step in bettering our understanding of dispersal abilities, gene flow, and behavior in the species. In this paper, an extended sampling of populations across Algonquin Provincial Park was performed to elucidate an effective scale of genetic differentiation in F. fletcheri. Genetic differentiation between sites was compared to interceding landscape composition, and digital dispersal models were developed, testing the hypothesis that F. fletcheri uses aquatic tributaries for dispersal between peatlands. Data were collected on 613 specimens from 15 populations, and population differentiation …
