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 …

A Model System In Landscape Genetics – The Insect Inhabitants Of Pitcher Plants, Gordana Gojko Rasic
Electronic Thesis and Dissertation Repository
Landscape genetics is a rapidly growing field that investigates how landscape and environmental features interact with microevolutionary processes to give rise to spatial genetic variation in populations. The ability to predict landscape effects on genetic patterns has been limited by the lack of studies conducted on more than one species, over multiple spatial scales and in replicated landscapes. A system that allows for such studies are the insect inhabitants of the purple pitcher plant (Sarracenia purpurea): the pitcher plant flesh fly (Fletcherimyia fletcheri), the midge (Metriocnemus knabi) and the mosquito (Wyeomyia smithii). In this thesis, I worked towards developing this …
