Name(s): Creator (cre): Hudson, Sean, Thesis advisor (ths): Murray, Dennis, Degree committee member (dgc): Davy, Christina, Degree committee member (dgc): Beresford, David, Degree granting institution (dgg): Trent University
Abstract: <p>Many rare and elusive species have low detection probabilities, thereby imposing unique challenges to monitoring and conservation. Here, we assess the detection probability of the Eastern Massasauga (Sistrurus catenatus) in contrast to a more common and conspicuous species, the Eastern Gartersnake (Thamnophis sirtalis). We found that patterns of detection probability differed between… more

Assessing Connectivity of Protected Area Networks and the Role of Private Lands in the United States

Name(s): Creator (cre): Bargelt, Lindsey, Thesis advisor (ths): Murray, Dennis, Thesis advisor (ths): Fortin, Marie-Josee, Degree committee member (dgc): Franklin, Steven, Degree granting institution (dgg): Trent University
Abstract: <p>Forestalling biodiversity loss through the establishment of protected areas is a universally accepted conservation strategy, yet despite established guidelines for protected area coverage and placement, much of the world is currently failing to meet its commitments to conservation planning and landscape protection. Calls for the United States to protect more land usually focus on the… more

Making eDNA count: Using environmental DNA (eDNA) to quantify relative larval amphibian abundance

Name(s): Creator (cre): Breton, Brie-Anne, Thesis advisor (ths): Murray, Dennis, Degree committee member (dgc): Wilson, Chris, Degree committee member (dgc): Lesbarrères, David, Degree granting institution (dgg): Trent University
Abstract: <p>Environmental DNA (eDNA) is rapidly becoming an established method for the detection of species in aquatic systems and has been suggested as a promising tool to estimate species abundance. However, the strength of the relationship between eDNA concentrations and taxon abundance (density/biomass) can vary widely between species. I investigated the relationship between eDNA concentration… more

How Abiotic and Biotic Factors Can Alter the Competitive Landscape in an Aggressive Species Complex (Genus: Ambystoma)

Name(s): Creator (cre): Leavitt, Jasper Siemann, Thesis advisor (ths): Murray, Dennis, Degree committee member (dgc): Dorken, Marcel, Degree committee member (dgc): Fox, Michael, Degree granting institution (dgg): Trent University
Abstract: <p>Competition is known to impact population dynamics through both indirect and direct interactions, and direct interactions can often lead to injury in one or both parties. As such, response to injury through tissue regeneration can be important for surviving post-competitive interaction. However, the impacts of outside factors like temperature and genome size (e.g. polyploidy) are not… more
