Freshwater aquatic systems in North America are being invaded by many different species, ranging from fish, mollusks, cladocerans to various bacteria and viruses. These invasions have serious ecological and economic impacts. Human activities such as recreational boating are an important pathway...

Sustaining the Recovery of Lake Sturgeon (Acipenser fulvescens) in the North Saskatchewan River of Alberta
DownloadSpring 2016
Nearly all Lake Sturgeon (Acipenser fulvescens) populations across North America have experienced losses to historic abundances estimated to be > 99%. This species is especially vulnerable to overharvest, habitat degradation, river fragmentation from dams, and is slow to recover due to life...

Climate change is currently a central problem in ecology, with far-reaching effects on species that may be diffcult to quantify. Ectothermic species which rely on environmental cues to complete successive stages of their life history are especially sensitive to temperature changes and so are good...

Testing for trade-offs between flight and reproduction in the mountain pine beetle (Coleoptera: Curculionidae) on two pine hosts
Download2019-01-01
Wijerathna, Asha, Whitehouse, Caroline, Proctor, Heather, Evenden, Maya
Mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae) adults fly to disperse before host colonization. The effect of flight on reproduction was tested by comparing the number and quality of offspring from beetles flown on flight mills to that of unflown...

Background: Defining what constitutes a resident care unit in nursing home research is both a conceptual and practical challenge. The aim of this paper is to provide evidence in support of a definition of care unit in nursing homes by demonstrating: (1) its feasibility for use in data collection,...

The genetic signature of rapid range expansions: How dispersal, growth and invasion speed impact heterozygosity and allele surfing
Download2014-01-01
Lewis, Mark A. , Coltman, David W. , Goodsman, Devin W., Cooke, Barry
As researchers collect spatiotemporal population and genetic data in tandem, models that connect demography and dispersal to genetics are increasingly relevant. The dominant spatiotemporal model of invasion genetics is the stepping-stone model which represents a gradual range expansion in which...

Dispersal can push population density below strong Allee thresholds ensuring the demise of small founding populations. As a result, for isolated populations of dispersing organisms, the minimum founding population size that enables establishment can be quite different from the Allee threshold. 2....

This thesis uses archaeological survey and historic documentary sources to reconstruct past mortality patterns and understand mortuary practices from the early 20th century Edson Cemetery in Edson, Alberta. Results show that the cemetery existed foremost as a place to enshrine the individual...

The relationship between body mass index, treatment, and mortality in patients with established coronary artery disease:a report from APPROACH.
Download2009
Padwal, R. A., Sharma, A., Kalanta-Zadeh, K., Oreopoulos, A., Norris, C.M., McAlister, F. A., Ezekowitz, J., Fonarow, G.C.
Our objective was to examine the association between body mass index (BMI) and survival according to the type of treatment in individuals with established coronary artery disease (CAD). Methods and results: Patients with CAD were identified in the Alberta Provincial Project for Outcome Assessment...

Tracing an Invasion : Phylogeography of Cactoblastis cactorum ( Lepidoptera : Pyralidae ) in the United States Based on Mitochondrial DNA
Download2008
Sperling, F. A. H., Simonsen, T. J., Brown, R. L.
Abstract: The adventive cactus moth Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), a widely used biological control agent for Opuntia Mill. cacti, was detected in Florida in 1989. Since then, it has spread along the Atlantic and Gulf Coasts of southeastern United States, threatening...
