Axial patterning of the developing vertebrate eye is crucial for proper axon pathfinding, as well as critically important morphogenetic events such as closure of the ocular fissure. Perturbations in eye morphogenesis can lead to ocular coloboma (failed ocular fissure closure) and microphthalmia...

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,...

Microalgae are a diverse group of photosynthetic microorganisms that have complex relationships with their surrounding bacteria, which are often controlled by the exchange of bioactive molecules. Emiliania huxleyi is a ubiquitous marine microalga, forming massive blooms, driving the marine carbon...

A burning question: The spatial response of woodland caribou to wildfire in northeastern Alberta
DownloadSpring 2020
The Canadian Federal Recovery Strategy for woodland caribou classifies areas burned by wildfire in the last 40 years as disturbed habitat for woodland caribou. This delineation of fire disturbance has major economic and social implications across Canada. Caribou have been shown to avoid burned...

The origin and timing of characteristic eukaryotic organelles is one of the key questions in the evolution of life on Earth. For the most part, widespread eukaryotic organelles (e.g., Golgi, mitochondria) have been inferred to be present in the last eukaryotic common ancestor (LECA) by examining...

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...

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...
