A molecular assessment of range expansion of the northern or virile crayfish (Orconectes virilis), crayfish-based community co-structure, and phylogeny of crayfish-affiliated symbionts
DownloadFall 2012
Geographical limits of a species’ range are determined in part by the environmental tolerances of that species, and also by its past and current ability to colonize new areas. Range shifts are a common occurrence in the evolutionary history of almost all taxa; however, anthropogenically-mediated...

Spring 2012
Voltage-gated potassium (Kv) channels regulate the flow of potassium ions across the cell membrane of nerves and muscles. Proper functioning of these and other voltage-gated ion channels is critical for an animal to sense the environment and respond quickly to stimuli. Dysfunctional Kv channels,...

Fall 2012
Conservationists have long debated how best to measure and conserve biodiversity. While many scientists called for long-term, large-scale ecological monitoring in the 1990's, the concurrent increased appreciation of statistical power and detectability-related sampling error meant that many...

Active heterotrophic microbial communities from polar desert soils of the Canadian High Arctic
DownloadFall 2012
Polar warming will lead to increased labile organic carbon in Arctic soils, both from the release of organic carbon stored in permafrost and increased plant production. The impact of increasing organic carbon on Arctic soil microbial community composition and activity is of great interest...

The recognition of virus infected cells by cytotoxic T lymphocytes is dependent on antigen presentation by MHC class I on the cell surface. Antigen presentation is critically dependent on the transporter associated with antigen processing (TAP), which facilitates the transport of peptides across...

Benthic Responses to Nitrogen and Phosphorus Deposition on Alpine Ponds in Banff National Park: A Replicated Whole-Ecosystem Experiment
DownloadFall 2012
Nitrogen (N) and Phosphorous (P) deposition at high elevations has increased by 40% over the last fifteen years, causing concern for the 3000+ alpine ponds in Banff National Park. A novel whole-ecosystem experiment was used to test for the effects of elevated N and P deposition on benthic...

Fall 2012
Teleosts rely on innate immunity to protect themselves from pathogens. Colony stimulating factor-1 (CSF-1) and its cognate receptor CSF-1R control survival, proliferation, differentiation and function of macrophages. Recently, a novel soluble form of CSF-1R (sCSF-1R) was identified in goldfish....

Comparative Analysis of the Anatomy of the Myxinoidea and the Ancestry of Early Vertebrate Lineages
DownloadFall 2012
The question of whether a hagfish is a true vertebrate or not has profound implications about the ancestry of the clade. New anatomical evidence allows a test of their systematic position. With dissections and serial sections of original specimens, and with a literature review, a comparative...
