Sex-Specific Graphs: Implication of Partitioning Population-Based Landscape Genetic analysis into Sex Components

22152-Thumbnail Image.png
Year: 2015, 2015
Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): Bertrand, Philip, Thesis advisor (ths): Wilson, Paul J., Thesis advisor (ths): Manseau, Micheline, Degree committee member (dgc): Bowman, Jeff, Degree granting institution (dgg): Trent University
Abstract: <p>Sex-specific genetic structure is a commonly observed pattern among vertebrate species. Facing differential selective pressures, individuals may adopt sex-specific life historical traits that ultimately shape genetic variation among populations. Although differential dispersal dynamics are commonly detected in the literature, few studies have investigated the potential effect of sex-… more

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

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

SPATIAL AND TEMPORAL GENETIC STRUCTURE OF WOLVERINE POPULATIONS

22866-Thumbnail Image.png
Year: 2015, 2015
Member of: Trent University Graduate Thesis Collection
Name(s): Creator (cre): Zigouris, Joanna, Thesis advisor (ths): Schaefer, James A, Thesis advisor (ths): Kyle, Christopher J, Degree committee member (dgc): Wilson, Paul J, Degree committee member (dgc): Bowman, Jeff, Degree granting institution (dgg): Trent University
Abstract: <p>Habitat loss and fragmentation can disrupt population connectivity, resulting in small, isolated populations and low genetic variability. Understanding connectivity patterns in space and time is critical in conservation and management planning, especially for wide-ranging species in northern latitudes where habitats are becoming increasingly fragmented. Wolverines (Gulo gulo) share… more

Incidental Take and Population Dynamics of Nesting Birds in a Red Pine (Pinus resinosa) Plantation Under Single-Tree Selection Harvesting

Name(s): Creator (cre): Fife, Ian, Thesis advisor (ths): Nol, Erica, Degree committee member (dgc): Abraham, Kenneth, Degree committee member (dgc): Bowman, Jeff, Degree granting institution (dgg): Trent University
Abstract: <p>I determined the direct influence of single-tree selection harvesting on the daily nest survival rates and nest success of 5 focal bird species within a monotypic red pine (Pinus resinosa) plantation on the western edge of the Oak Ridges Moraine in southern Ontario, Canada. I located and monitored 290 nests during the 2012 and 2013 breeding season. I used the logistic-exposure method to… more
