Name(s): Creator (cre): Brown, Andrew, Thesis advisor (ths): Nol, Erica, Degree committee member (dgc): Davy, Christina, Degree committee member (dgc): Catlin, Daniel, Degree granting institution (dgg): Trent University
Abstract: <p>I used 31 years of Semipalmated Plover (Charadrius semipalmatus) population data to assess the effects of vital rates on a local breeding population of plovers in Churchill, Manitoba, Canada. I used three similar Bayesian Integrated Population Models (IPMs), with the last a coupled IPM population viability analysis (PVA) approach to predict the impact of changing spring temperatures on… more

Abstract: <p>Northern flying squirrels (NFS) are mycophagous specialists (fungi-dominated diet) thatmay be displaced with southern flying squirrel (SFS) range expansion, thereby limiting
fungal dispersal in forest communities. To understand the implications of squirrel
species turnover on mycophagy, we investigated the home ranges of both flying squirrel
species who are living in stable sympatry. We… more

Length of stay and habitat use of shorebirds at two migratory stopover sites in British Columbia, Canada

Name(s): Creator (cre): Blondin, Anne, Thesis advisor (ths): Nol, Erica, Degree committee member (dgc): Drever, Mark, Degree committee member (dgc): Flemming, Scott, Degree committee member (dgc): Burness, Gary, Degree granting institution (dgg): Trent University
Abstract: <p>Many species of shorebirds depend on stopover sites to rest and refuel during their long-distance migrations. To determine how shorebirds use migratory stopover sites, we tracked three species of shorebirds at two stopover sites in British Columbia, Canada from 2018-2021 during northward and southward migration using automated telemetry. Western Sandpipers (Calidris mauri) stayed longer… more

Bottom-up pathways for arthropods and forest breeding birds in a southern Ontario forest

Abstract: <p>Long-term avian population declines, particularly for the avian insectivore guild, are a conservation concern. With widespread and continuing population trends, climate change and its negative effects on avian food resources is a plausible cross-species driver. My goal was to evaluate whether bottom-up trophic effects of climate change could be influencing avian populations. I used a… more
