DHR51 as a coordinator of heme biosynthesis and steroid hormone production to time metamorphosis in Drosophila melanogaster
DownloadFall 2019
Development from a juvenile to an adult animal is driven by pulses of steroid hormones released at precise developmental times. Inputs from the environment, timing cues, and nutritional factors are all coordinated to produce a steroid hormone pulse. Insects and in particular, the fruit fly...

Squamate reptiles comprise over 10,000 living species and hundreds of fossil species of lizards, snakes and amphisbaenians, with their origins dating back at least as far back as the Middle Jurassic. Despite this enormous diversity and a long evolutionary history, numerous fundamental questions...

Dematiaceous hyphomycetes are a taxonomically diverse artificial assemblage of conidial fungi that have dark pigments known as melanins in their walls. Select dematiaceous hyphomycetes from the Coniochaetales, Pleosporales, and Helotiales obtained from arctic and alpine bryophytes and vascular...

Diet composition and prey selectivity of gray wolves (Canis lupus) in Prince Albert National Park, Saskatchewan
DownloadSpring 2019
Plains bison (Bison bison bison) were nearly driven to extinction in the late 19th century due to overhunting and habitat loss, and populations occurring within their historic range and co-existing with natural predators are exceedingly rare. Studies examining gray wolf (Canis lupus) predation on...

Differential expression of nicotinic acetylcholine receptor subunits is critical for the embryonic development of zebrafish muscle and neuromuscular junction
DownloadSpring 2020
Nicotinic acetylcholine receptors (nAChRs) are ligand gated ion channels primarily expressed on muscle fibers and neurons. They are comprised of five subunits arranged in different stoichiometries. nAChRs expressed at the neurons are comprised of different combinations of α1-10 and β1-4 subunits,...

The DEAD-box cyanobacterial RNA helicase redox, or CrhR, in Synechocystis sp. PCC 6803 is capable of unwinding dsRNA and in annealing ssRNA in a bidirectional ATP-dependent manner. This is a feature shared by only four other DEAD-box RNA helicases. Two of which, the eukaryotic p68 and p72...

Disentangling a freshwater amphipod–acanthocephalan system from ecological and molecular perspectives
DownloadSpring 2019
One of the major goals in ecological research is to understand factors that influence distribution, diversity and prevalence of parasites and their hosts. How hosts are distributed geographically clearly restricts the spatial distribution of associated obligatory parasites. This restriction is...

Disentangling competitive processes to better understand their drivers and consequences in a native grassland community
DownloadSpring 2021
Competition is often highlighted as a major force influencing community structure. However, there are multiple facets of competition that may have independent and differential impacts, making the understanding of what drives competition and how it structures communities difficult. In this thesis,...
