Enduring Attack: Defensive Posture in Terrestrial Salamanders (Genus: Ambystoma) and Their Predator-Prey Interactions on Pelee Island, Canada

Year: 2018, 2018
Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): Myette, Alexander, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Bowman, Jeff, Degree committee member (dgc): Nol, Erica, Degree granting institution (dgg): Trent University
Abstract: <p>Numerous prey taxa employ defensive postures for protection against attack by predators. Defensive postures mitigate predation risk at various stages of the predator-prey sequence, including through crypsis, mimicry, thanatosis, aposematism, and deflection. In terrestrial salamanders, defensive postures may be aposematic, or deflect attacks away from vital body parts and towards the tail… more

Corticosterone Promotes Development of Cannibalistic Morphology and Inhibits Tissue Regeneration in Axolotls (Ambystoma mexicanum)

Name(s): Creator (cre): MacFarlane, Shawn Patric Harris, Thesis advisor (ths): Kerr, Leslie R, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Kapron, Carolyn M, Degree granting institution (dgg): Trent University
Abstract: <p>Salamanders are capable of tissue regeneration throughout all life-stages, which requires the dedifferentiation of mature cells to regrow lost tissues. Dedifferentiation is promoted by degradation of the extracellular matrix by matrix metalloproteases, as well as lysosomal degradation of intracellular and cell-surface proteins that mark cells as part of a mature lineage. Salamanders are… more

Time to adapt: Characterizing adaptive genetic variation of Canada lynx using coding trinucleotide repeats

22278-Thumbnail Image.png

Name(s): Creator (cre): Prentice, Melanie Brooke, Thesis advisor (ths): Wilson, Paul J, Thesis advisor (ths): Bowman, Jeff, Degree committee member (dgc): Murray, Dennis L, Degree granting institution (dgg): Trent University
Abstract: <p>To better understand species' resilience to climate change and implement solutions, we must conserve environments that maintain standing adaptive genetic variation and the potential generation of new beneficial alleles. Coding trinucleotide repeats (cTNRs) providing high-pace adaptive capabilities via high rates of mutation are ideal targets for mitigating the decline of species at… more

Stoichiometric food quality affects responses of Daphnia to predator-derived chemical cues

Name(s): Creator (cre): Bell, Alex T.C., Thesis advisor (ths): Frost, Paul C, Thesis advisor (ths): Murray, Dennis L, Degree committee member (dgc): Beresford, David V, Degree granting institution (dgg): Trent University
Abstract: <p>While both resource quality and predator-derived chemical cues can each have profound effects on zooplankton populations and their function in ecosystems, the strength and nature of their interactive effects remain unclear. We conducted laboratory experiments to evaluate how stoichiometric food quality (i.e., algal carbon (C):phosphorus (P) ratios) affects responses of the water flea,… more
