Sexual Selection, Sex Allocation and Stochasticity: A Study of Mating Patterns in Sagittaria latifolia

Kwok_trentu_0513D_11264-Thumbnail Image.png

Year: 2025, 2025

Member of: Trent University Graduate Thesis Collection

Name(s): Creator (cre): Kwok, Allison, Thesis advisor (ths): Dorken, Marcel E, Degree committee member (dgc): Freeland, Joanna R, Degree committee member (dgc): Nol, Erica, Degree granting institution (dgg): Trent University

Abstract: <p>Diversity of flowers in flowering plants is understood to facilitate mating success, and yet understanding the relationships between plant sexual diversity and mating patterns remains a challenge. In this thesis, I used Sagittaria latifolia, an aquatic plant with unique sexual systems, to investigate relationships between plant sexual diversity, mating patterns, and reproductive success… more

Factors Affecting Nest Survival and Nest Site Selection for the Lesser Yellowlegs (Tringa flavipes)

Year: 2025, 2025

Member of: Trent University Graduate Thesis Collection

Name(s): Creator (cre): Brown, Courtland Weston, Thesis advisor (ths): Nol, Erica, Thesis advisor (ths): Christie, Katie, Degree committee member (dgc): Smith, Paul A., Degree granting institution (dgg): Trent University

Abstract: <p>The Lesser Yellowlegs (Tringa flavipes) is a steeply declining shorebird that breeds across boreal North America. I studied nest survival in Anchorage, Alaska, USA and Churchill, Manitoba, Canada and nest site selection factors in Churchill. Nests were monitored at each site and daily nest survival rates (DSR) were calculated based on a maximum likelihood approach. Overall nest survival… more

Effects of a Topographical Gradient on Food Availability, Nest Site Selection, Nest Initiation, and Nest Success for Two Small, Low Arctic Breeding Bird Species

Member of: Trent University Graduate Thesis Collection

Name(s): Creator (cre): Bonnett, Sarah, Thesis advisor (ths): Nol, Erica, Thesis advisor (ths): Smith, Paul A, Degree committee member (dgc): Nol, Erica, Degree committee member (dgc): Smith, Paul A, Degree committee member (dgc): Brown, Glen, Degree granting institution (dgg): Trent University

Abstract: <p>Climate change affects birds' reproductive ecology by altering breeding timing, distribution, and habitat suitability. Snowmelt patterns complicate these changes affecting habitat availability and suitability for birds and their arthropod prey. Snow varies as a function of both large-scale climate patterns and local-scale topography. I used elevational gradients as a proxy for local… more

Phenology and Movement Ecology of Mid-Atlantic Breeding Shorebirds

MacLaurin_trentu_0513N_11307-Thumbnail Image.png

Year: 2025, 2025

Member of: Trent University Graduate Thesis Collection

Name(s): Creator (cre): MacLaurin, Trevor, Thesis advisor (ths): Nol, Erica, Degree committee member (dgc): Smith, Paul A., Degree committee member (dgc): Senner, Nathan R., Degree granting institution (dgg): Trent University

Abstract: <p>Migration, space use, and phenology play key roles in shaping avian populations and are therefore critical for conservation. My thesis examines the migration strategies and non-breeding spatial requirements of Virginia's beach-nesting American Oystercatchers (Haematopus palliatus), as well as the nesting phenology of mid-Atlantic American Oystercatchers and Piping Plovers (… more
