Batten disease is caused by mutations in 1 of the 13 ceroid lipofuscinosis neuronal (CLN) genes (CLN1-CLN8, CLN10-CLN14), each of which causes an NCL subtype when mutated. One of the NCL subtypes, CLN5 disease, is… more

Molecular tools can also illustrate how historical processes affect contemporary genetic variation to predict how current population trends may… more

The ability to maintain or change genetic mosaics of populations becomes key to persistence, as species increasingly need to adapt to rapidly changing… more

Abstract: <p>Hybridization contributes to the genetic diversity and can impact speciation. This study investigates the genetic evidence of recent hybridization under climate change in sympatric populations of northern and southern flying squirrels in Ontario. Using low-coverage whole-genome sequences, my research examines the existing population structure and measures the genomic variation of the… more Full Text: 1 2 3 GENOMIC SIGNATURES OF SPECIATION IN SYMPATRIC FLYING SQUIRRELS 4 5 6 7 8 9 A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science 10 …

Abstract: <p>Wildlife translocation programs are widely employed as a strategy to reintroduce extirpated species into regions they once inhabited but no longer do. Reintroduction programs can be successful at re-establishing extirpated populations and also provide unique opportunities to study post-reintroduction population dynamics and behavioural ecology. The wild turkey (Meleagris gallopavo) is a… more

Abstract: <p>In endotherms, physiological functioning is optimized within a narrow range of tissue temperatures, meaning that the capacity to dissipate body heat is an important parameter for thermoregulation and organismal performance. Yet, experimental research has found mixed support for the importance of heat dissipation capacity as a constraint on reproductive performance. To investigate the… more Full Text: The effects of heat dissipation capacity on avian physiology and behaviour A Thesis 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>Warming climates have had various consequences on terrestrial and aquatic food webs that are expected to persist. There is evidence suggesting that certain organisms are better equipped to handle changing climates compared to others. Therefore, the purpose of my thesis was to study the adaptability of Daphnia under temperature stress and nutrient limitation. First, to examine the effects… more Full Text: DAPHNIA PULICARIA RESPONSES TO TEMPERATURE AND NUTRIENTS STRESS: WHAT HAPPENS WHEN THE HEAT IS ON?

Abstract: <p>I assessed how organisms having multiple biotic attributes may have conflicting niche determinants, and whether the realized niche reflects single or multiple attributes. All-female salamanders engage in two biotic states: hybridism and reproductive parasitism. Hybrids should occupy areas transitional to those used by parental species, whereas parasites that engage in competition with… more Full Text: Complex niche determinants in terrestrial salamanders: Does hybridism or reproductive parasitism explain large-scale patterns of distribution?
