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 …

Identity And Diversity Of Agaricomycetes (Fungi: Basidiomycota) In Temperate Agricultural Soils, Barbara D. Bahnmann
Digitized Theses
The objectives of this study were to identify and to compare the species richness, community composition and genetic diversity of Agaricomycetes in Michigan agricultural soils. Ribosomal DNA sequences were obtained from soils in four treatments: conventional till monocrop, no-till monocrop, historically tilled grassland and never-tilled grassland. The Agaricales dominated the community, with 85 % of all detected taxa. The taxonomic composition of conventional till plots was different from other plots due to the high prevalence of Pneumatospora (Cantharellales) and Lachnella/Calathella (Agaricales) clades and the absence of Hygrocybe (Agaricales) and Polyporales clades. These latter clades dominated less disturbed treatments. Genetic diversity …
