DIATOM ASSEMBLAGES IN RELATION TO WATER-DEPTH GRADIENTS IN EIGHT BOREAL SHIELD LAKES FROM NORTHWESTERN ONTARIO, CANADA
The uncertainty surrounding the impact of future changes in climate and water resources has created renewed interest on how lakes have responded to drought in the past. There is a need to determine potential future ...
The behaviour of largemouth bass in Lake Opinicon, Ontario: A biological perspective for the evaluation of Murphy Bay fish sanctuary
This study provides a biological perspective on the potential of using year-round sanctuaries to protect largemouth bass (Micropterus salmoides). Although the Rideau Lakes bass sanctuaries have been present for more than ...
Developmental Regulation of Cell Fate And Disease Resistance in Plants
Plant-wide communication between tissues and cells is organized, in part, by a suite of compounds called hormones. I have chosen to focus on the effects of one plant hormone, ethylene; how its synthesis is controlled and ...
Cellular Mechanisms Involved in Stress-Induced Coma and CNS Spreading Depression in the Locust
Spreading depression (SD) is an interesting and important phenomenon due to its role in mammalian pathologies such as migraine, seizures, and stroke. Until recently investigations of the mechanisms involved in SD have ...
Experimental Evidence of Transitive Inference in Black-Capped Chickadees
Many recent discoveries in animal cognition have shown that species once thought to be relatively simple are in fact capable of complex problem-solving in accordance with their ecological needs. These findings have resulted ...
Evolution of Oxidative Metabolism in Fishes
My study investigated the evolution of oxidative metabolism in fishes. While intense selection for, or against, non-synonymous point mutations in coding sequence drives the evolution of mitochondrial OXPHOS genes, ...
Paleolimnological assessment of environmental changes occurring on Pim Island, Nunavut, High Arctic Canada
Despite the documented sensitivity of polar environments, long-term monitoring data are especially sparse in these regions. Diatom-based paleolimnology has contributed significantly to understanding the response of Arctic ...
GENETIC NONINVASIVE CAPTURE-RECAPTURE TECHNIQUES TO MANAGE POLAR BEARS: A PILOT STUDY
Global polar bear (Ursus maritimus) population numbers are expected to decline steadily over the next 50 years. A noninvasive genetic survey of polar bear numbers may be a useful addition to traditional aerial capture mark ...
A Duality in Mammalian Glucocorticoid Signaling
I tested a prevalent assumption in glucocorticoid research that states that each species has a dominant glucocorticoid, and cortisol and corticosterone are interchangeable steroids. A comprehensive analysis of historical ...
