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 Full Text: SPATIAL AND TEMPORAL GENETIC STRUCTURE OF WOLVERINE POPULATIONS A dissertation submitted to the Committee on Graduate Studies in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Faculty of Arts and Science TRENT …

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 Full Text: FACTORS AFFECTING ROAD MORTALITY OF REPTILES AND AMPHIBIANS ON THE BRUCE PENINSULA A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of …

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 Full Text: INCIDENTAL TAKE AND POPULATION DYNAMICS OF NESTING BIRDS IN A RED PINE (Pinus resinosa) PLANTATION IN SOUTHERN ONTARIO UNDER SINGLE-TREE SELECTION HARVESTING A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the …

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 Full Text: SEX-SPECIFIC GRAPHS : IMPLICATION OF PARTITIONING POPULATION-BASED LANDSCAPE GENETIC ANALYSIS INTO SEX COMPONENTS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the …
