Name(s): Creator (cre): Mondoux, Courtney C., Thesis advisor (ths): Wilson, Paul J, Thesis advisor (ths): Obbard, Martyn E, Degree committee member (dgc): Petersen, Stephen D, Degree granting institution (dgg): Trent University
Abstract: <p>Polar bears are generally described as solitary, but features of their life cycles and </p><p>habitats regularly necessitate interaction. Effective conspecific assessment, including accurate </p><p>recognition and discrimination, likely confers benefits, especially to females accompanied by </p><p>dependent young. Individuals in the Southern (SH) and… more

Name(s): Creator (cre): Watt, Cristen Margaret, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Wilson, Paul J, Degree committee member (dgc): Bowman, Jeff, Degree granting institution (dgg): Trent University
Abstract: <p>Mountain ranges are often thought to restrict movement of wildlife, yet previous studies evaluating the role of the Rocky Mountains as a dispersal barrier for Canada lynx (Lynx canadensis) have been contradictory. Our study uses neutral microsatellite loci to evaluate the role of the Rocky Mountains as a barrier to gene flow for lynx. Although lynx exhibited low genetic differentiation,… more

Name(s): Creator (cre): Morris, Kimberley Yana, Thesis advisor (ths): Wilson, Paul J, Thesis advisor (ths): Bowman, Jeff, Degree committee member (dgc): Shulte-Hostedde, Albrecht, Degree granting institution (dgg): Trent University
Abstract: <p>The release of domestic organisms to the wild is considered a threat to </p><p>biodiversity because the introduction of domestic genes through interbreeding can </p><p>negatively impact wild conspecifics via outbreeding and local extinction. In North </p><p>America, captive American mink (Neovison vison) are frequently escaping into the wild, </p… more
