Spatial predation risk for elk (Cervus elaphus) in a multi-predator community on the Rocky Mountain East Slopes, Alberta
DownloadSpring 2019
There is evidence that prey can perceive the risk of predation, and may alter habitat selection, increase vigilance, alter social grouping, and reduce migratory behaviour in response. Previous approaches that quantify predation risk have focused on measuring the different phases of predation such...

Speciation and hybridization in the Old World swallowtail butterfly (Papilio machaon) species complex
DownloadSpring 2016
Species delimitation is fundamental to evolutionary biology. However the process is far from straightforward in systems with complex evolutionary histories, and the concept of species as taxonomic hypotheses is often overlooked in many biological disciplines. Here I investigate species...

Species delimitation in the Choristoneura fumiferana species complex (Lepidoptera: Tortricidae)
DownloadFall 2010
Species identifications have been historically difficult in the economically important spruce budworm (Choristoneura fumiferana) pest complex. Morphological, ecological, behavioural, and genetic characters have been studied to try to understand the taxonomy of this group, but diagnostic character...

Benthic marine habitats in Canada have been well-sampled since the annual groundfish survey commenced in 1970. However, trawl surveys cover only non-rocky sediments and many species collected are not identified to lower taxa, leaving large gaps in our understanding of benthic diversity. Sponges...

Sponges (Porifera) are abundant in most marine and freshwater ecosystems, and as suspension feeders they play a crucial role in filtering the water column. Their active pumping enables them to filter up to 900 times their body volume of water per hour, recycling nutrients and coupling the benthic...

Stable knock-in of duck RIG-I into DF-1 chicken cells via CRISPR/Cas9 homology directed repair
DownloadFall 2020
Chickens and ducks differ in their susceptibility to avian influenza virus infection. Ducks are the primordial hosts and reservoir of avian influenza A viruses. Mallard ducks can asymptomatically harbour high-pathogenicity avian influenza (HPAI) and low-pathogenicity avian influenza (LPAI)....

Statistical and In-field Challenges Involved in Quantifying Crop Nitrogen Use Efficiency (NUE) and Spatial Soil Fertility in Central Alberta
DownloadSpring 2020
Modern agriculture faces the conundrum of a looming threat of food scarcity and heightened pressure on natural resources to address and sustain increasing food demand. Improving nutrient use efficiency is crucial to sustainable food production. It can be helpful in tackling this critical...
