Name(s): Creator (cre): May, Chelsea Marie, Thesis advisor (ths): Fox, Michael G, Thesis advisor (ths): Burness, Gary, Degree committee member (dgc): Beresford, David V, Degree granting institution (dgg): Trent University
Abstract: <p>Since its introduction to North America in the 1990s, the Round Goby has spread throughout the Great Lakes, inland through rivers and is now moving into small tributary streams, a new environment for this species in both its native and invaded ranges. I explored density and temporal occupation of Round Gobies in four small streams in two systems in south-central Ontario, Canada in order… more

The Diversity, Biogeography, and Functional Traits of Native Bees from Ontario's Far North and Akimiski Island, Nunavut

Name(s): Creator (cre): Vizza, Kayla Marie, Thesis advisor (ths): Beresford, David V, Degree committee member (dgc): Schaefer, James, Degree granting institution (dgg): Trent University
Abstract: <p>Bees (clade Anthophila), are poorly studied in northern Canada, as these regions can be difficult to access and have a short growing season. This study examined bees from two such regions: Ontario's Far North, and Akimiski Island, Nunavut. I present this study as the largest biogeographical study of bees performed in these remote areas to enhance knowledge of northern native bees. I… more

Do birds of a feather flock together: An investigation of sandhill crane (Antigone canadensis) populations using non-invasive feathers as a source of DNA

Name(s): Creator (cre): Kelly, Crystal, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Kyle, Chris J, Degree committee member (dgc): Beresford, David V, Degree granting institution (dgg): Trent University
Abstract: <p>Populations have long been delineated by physical barriers that appear to limit reproduction, yet increasingly genetic analysis reveal these delineations to be inaccurate. The eastern and mid-continent populations of sandhill cranes are expanding ranges which is leading to convergence and warrants investigation of the genetic structure between the two populations. Obtaining blood or… more

Syrphidae (Diptera) of northern Ontario and Akimiski Island, Nunavut: new diversity records, trap analysis, and DNA barcoding

Name(s): Creator (cre): Vezsenyi, Kathryn Anne, Thesis advisor (ths): Beresford, David V, Thesis advisor (ths): Schaefer, James A, Degree committee member (dgc): Skevington, Jeffrey H, Degree committee member (dgc): Crins, William, Degree granting institution (dgg): Trent University
Abstract: <p>Syrphids, also known as hover flies (Diptera: Syrphidae) are a diverse and widespread family of flies. Here, I report on their distributions from a previously understudied region, the far north of Ontario, as well as Akimiski Island, Nunavut. I used samples collected through a variety of projects to update known range and provincial records for over a hundred species, bringing into… more
