Genetic population structure of walleye (Sander vitreus) in northern Alberta and application to species managementDownload
Walleye (Sander vitreus) is an economically valuable freshwater fish throughout North America. In Alberta, pressure from sport fishing and commercial fishing make effective management and protection of this species crucial to its sustainability. Walleye from 12 Alberta lakes were genetically...
An experiment was conducted to determine if spatial nutrient heterogeneity affects mean plant size or size hierarchies in experimental populations of the weedy annual Abutilon theophrasti Medic. (Malvaceae). Heterogeneity was imposed by alternating 8 X 8 X 10 cm blocks of low and high nutrient...
Polar bears (Ursus maritimus) were among the first large mammals to be assessed for genetic variation in the wild, and they remain a common subject of genetics studies. Although recent advances in genotyping technology have allowed for more accurate determination of population structure and the...
Population Structure and Gene Flow in the White Pine Weevil, Pissodes strobi (Coleoptera: Curculionidae)Download
Abstract: The white pine weevil, Pissodes strobi (Peck), is a major source of damage to young spruce and pine trees across North America. The species contains a substantial amount of genetic, morphological, and behavioral variation, and identification of patterns of genetic variation on a broad...
I investigated the population and landscape genetics of Arctic Grayling (Thymallus arcticus) distributed throughout several connected river systems in Alberta, Canada. Broad- and fine-scale population structure was examined by genotyping nine microsatellite loci in 1,116 Arctic Grayling captured...
Traditionally, population delineation has been determined using mark-recapture, band returns, and more recently, telemetry, geologgers and genetics. But telemetric and genetic population structure data have rarely been examined concurrently to explore differences and similarities. I define a...
Population-level Responses to Nutrient Heterogeneity and Density by Abutilon Theophrasti (Malvaceae): An Experimental Neigborhood ApproachDownload
An experimental approach was used to examine the effects of spatial nutrient heterogeneity and planting density on the sizes of plants within populations of Abutilon theophrasti. Planting locations were generated using random numbers and replicated among populations growing on two different...
Understanding how populations are structured and how they use natural and anthropogenic spaces is essential for effective wildlife management. A total of 510 barren-ground (Rangifer tarandus groenlandicus), 176 boreal (R. t. caribou), 11 mountain woodland (R. t. caribou), and 39 island (R. t....
