    The Effects of Local, Landscape, and Temporal Variables on Bobolink Nest Survival in Southern Ontario

    Year: 2020, 2020
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Fromberger, Monica Ann, Thesis advisor (ths): Nol, Erica, Thesis advisor (ths): Campomizzi, Andrew, Degree committee member (dgc): Schaefer, Jim, Degree committee member (dgc): Nocera, Joe, Degree granting institution (dgg): Trent University
    Abstract: <p>Populations of grassland birds, including the Bobolink (Dolichonyx oryzivorus), are experiencing steep declines due to losses of breeding habitat, land use changes, and agricultural practices. Understanding the variables affecting reproductive success can aid conservation of grassland species. I investigated 1) whether artificial nest experiments accurately estimate the impacts of cattle… more

    Detectability and its role in understanding upland sandpiper (Bartramia longicauda) occurence in the fragmented landscape of southern Ontario

    Year: 2019, 2019
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Chronowic, Daniel Adam, Thesis advisor (ths): Nol, Erica, Degree committee member (dgc): Bowman, Jeff, Degree committee member (dgc): Nocera, Joe, Degree granting institution (dgg): Trent University
    Abstract: <p>Upland Sandpipers (Bartramia longicauda), like many grassland birds, are undergoing population decline in parts of their range. Habitat fragmentation and change have been hypothesized as potential causes of decline. I used citizen-science occurrence data from Wildlife Preservation Canada's Adopt-A-Shrike Loggerhead Shrike (Lanius ludovicianus) program in conjunction with validation… more

    Regional differences in the whistles of Australasian humpback dolphins (genus Sousa)

    Year: 2015, 2015
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Hoffman, Jordan Michael, Thesis advisor (ths): White, Bradley N, Degree committee member (dgc): Nocera, Joe, Degree committee member (dgc): Schaefer, James, Degree granting institution (dgg): Trent University
    Abstract: <p>Most delphinids produce narrowband frequency-modulated whistles with a high level of plasticity to communicate with conspecifics. It is important to understand geographic variation in whistles as signal variation in other taxa has provided insight into the dispersal capabilities, genetic divergence and isolation among groups, and adaptation to ecological conditions. I investigated… more

    Factors affecting road mortality of reptiles and amphibians on the Bruce Peninsula

    Year: 2015, 2015
    Member of: Trent University Graduate Thesis Collection
    Name(s): Creator (cre): Stinnissen, Tricia, Thesis advisor (ths): Schaefer, James A, Degree committee member (dgc): Nocera, Joe, Degree committee member (dgc): Bowman, Jeff, Degree granting institution (dgg): Trent University
    Abstract: <p>Road mortality is one of the leading causes of global population declines in reptiles and amphibians. Stemming losses from reptile and amphibian road mortality is a conservation priority and mitigation is a key recovery measure. I developed a model of road mortalities relative to non-­‐mortalities, based on predictors varying across space (road surface type, traffic volume, speed limit,… more

    Human Activity and Habitat Characteristics Influence Shorebird Habitat Use and Behaviour at a Vancouver Island Migratory Stopover Site

    Year: 2015, 2015

    Name(s): Creator (cre): Murchison, Colleen Roxanne, Thesis advisor (ths): Nol, Erica, Degree committee member (dgc): Nocera, Joe, Degree committee member (dgc): Burness, Gary, Degree granting institution (dgg): Trent University
    Abstract: <p>Pacific Rim National Park Reserve's 16 km of coastal beaches attract many thousands of people and shorebirds every year. To identify locations where shorebirds concentrate and determine the impact of human activity and habitat characteristics on shorebirds, I conducted shorebird and visitor surveys at 20 beach sectors during fall migration in 2011 to 2013 and spring migration in… more
