    Habitat use within and among roosts of chimney swifts (Chaetura pelagica)

    Name(s): Creator (cre): Farquhar, Melanie Lisa, Thesis advisor (ths): Nocera, Joseph J, Degree committee member (dgc): Nol, Erica, Degree committee member (dgc): Burness, Gary, Degree granting institution (dgg): Trent University
    Abstract: <p>Chimney swifts are listed as Threatened nationally and in many provinces within Canada due to rapid population declines. I examined large-scale spatial variation in the maximum size of chimney swift roosts at the northern edge of their range to identify where larger roosts occur. I used multi-sourced data collected across Ontario and Quebec between 1998 and 2013. I found that larger… more

    Using DNA Barcoding to Investigate the Diet and Food Supply of a Declining Aerial Insectivote, the Barn Swallow (Hirundo rustica)

    Name(s): Creator (cre): McClenaghan, Beverly, Thesis advisor (ths): Nol, Erica, Degree committee member (dgc): Nocera, Joseph J, Degree committee member (dgc): Beresford, David V, Degree committee member (dgc): Kerr, K, Degree granting institution (dgg): Trent University
    Abstract: <p>Barn Swallow (Hirundo rustica) populations have declined in North America over the past 40 years and they are listed as Threatened in Ontario, Canada. Changes in the food supply have been hypothesized as a potential cause of this population decline. I used DNA barcoding to investigate the diet and food supply of Barn Swallows and to determine if the food supply affects their reproductive… more

    Using automated radio-telemetry to link food availability, reproductive success, and habitat use of Barn Swallows (Hirundo rustica erythrogaster)

    Year: 2018, 2018

    Name(s): Creator (cre): Lenske, Ariel, Thesis advisor (ths): Nocera, Joseph J, Degree committee member (dgc): Schaefer, James A, Degree committee member (dgc): Nol, Erica, Degree granting institution (dgg): Trent University
    Abstract: <p>Drivers of North American Barn Swallow population declines are not well understood, but foraging habitat loss is thought to be a contributing factor. Determining patterns of habitat use is challenging for swallows because they move rapidly but are too small to carry GPS tags. We showed that automated radio-telemetry could be used to track the movements of swallows with enough accuracy (… more

    Intra-seasonal Variation in Black Tern Nest-site Selection and Survival

    Year: 2018, 2018

    Name(s): Creator (cre): von Zuben, Valerie, Thesis advisor (ths): Nocera, Joseph J, Thesis advisor (ths): Nol, Erica, Degree committee member (dgc): Beresford, David V, Degree granting institution (dgg): Trent University
    Abstract: <p>Resources and risk are in constant flux and an organism's ability to manage change may improve their likelihood of persistence. I examined intra-seasonal variation in nest-site selection and survival of a declining wetland bird, the Black Tern (Chlidonias niger surinamensis). I modelled nest site occupancy and survival of early and late-nesting birds as a function of static and… more
