Effects of Invasive Wetland Macrophytes on Habitat Selection by Turtles

Year: 2019, 2019
Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): Angoh, Siow Yan Jennifer, Thesis advisor (ths): Davy, Christina, Thesis advisor (ths): Freeland, Joanna, Degree committee member (dgc): Bowman, Jeff, Degree granting institution (dgg): Trent University
Abstract: <p>Invasive species that alter habitats can have significant impacts on wildlife. The invasive graminoids Phragmites australis (Cav.) Trin. ex Steud, hereafter Phragmites, and Typha × glauca Godr. are rapidly spreading into North American wetlands, replacing native vegetation. Invasive Phragmites is considered a potential threat to several species-at-risk (SAR), including some turtle… more

Habitat selection by sympatric Canada lynx (Lynx canadensis) and bobcat (Lynx rufus)

Name(s): Creator (cre): Morin, Samantha, Thesis advisor (ths): Bowman, Jeff, Thesis advisor (ths): Fortin, Marie-Josee, Degree committee member (dgc): Schaefer, Jim, Degree granting institution (dgg): Trent University
Abstract: <p>Range expansion by the bobcat (Lynx rufus) may be contributing to range contraction by the Canada lynx (Lynx canadensis), but interactions between them are not well understood. To investigate the potential for competition, I conducted a literature review of hierarchical habitat selection by these two species. I determined that the lynx and the bobcat select different resources at the… more

Hybridization dynamics in cattails (Typha spp.,) in northeastern North America: niche segregation, pollen dispersal, mating patterns, and the importance of local-scale processes

Name(s): Creator (cre): Pieper, Sara Jean, Thesis advisor (ths): Dorken, Marcel, Thesis advisor (ths): Freeland, Joanna, Degree committee member (dgc): Bowman, Jeff, Degree committee member (dgc): Wilson, Chris, Degree granting institution (dgg): Trent University
Abstract: <p>Interspecific hybridization is an important evolutionary process which can contribute to the invasiveness of species complexes. In this dissertation I used the hybridizing species complex of cattails (Typha spp., Typhaceae) to explore some of the processes that could contribute to hybridization rates. Cattails in northeastern North America comprise the native T. latifolia, the non-native… more

Risk of Mortality for the Semipalmated Plover (Charadrius semipalmatus) Throughout Its Life Cycle

Name(s): Creator (cre): Williams, Simone Elise, Thesis advisor (ths): Nol, Erica, Degree committee member (dgc): Burness, Gary, Degree committee member (dgc): Bowman, Jeff, Degree granting institution (dgg): Trent University
Abstract: <p>Three long-term mark and recapture/resight data sets of individually marked</p><p>Semipalmated Plovers (Charadrius semipalmatus) were analyzed using Cormack-Jolly-</p><p>Seber models. Data came from two breeding populations (Churchill, Manitoba, Canada,</p><p>n=982, and Egg Island, Alaska, USA, n=84) and one overwintering population</p><p>(… more

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

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
