Spring 2023
As of 2016, the global annual production of plastic was 330 million metric tonnes (Plastics Europe, 2017). This staggering number is expected to double over the next 20 years as consumption increases (Plastics Europe, 2017; Lebreton et al., 2019). Less than half of the plastic produced reaches a...

Development and Evolution of Complex Reproductive Traits in the Brassicaceae and Cleomaceae
DownloadSpring 2023
Flowering plants exhibit a bewildering diversity of forms, which raises fundamental questions on how that diversity arises. A cornerstone of evolutionary developmental biology is the expansion of comparative landscapes and establishment of focal clades that enable investigation of complex and...

Spring 2023
Artificial light is one of the fastest growing pollutants worldwide and conveys biological effects from molecular to ecosystem levels on many taxa, including birds. Birds flying at night sometimes collide with illuminated structures, but artificial light can have other effects that are less...

Spring 2023
Polar bear conservation faces significant challenges under Arctic warming, especially with respect to habitat loss and the resulting impacts on their seasonal energetic uptake and maintenance. Polar bears rely on sea ice for hunting, mating, denning, and rearing of offspring, and the availability...

Biological and environmental correlates of cougar (Puma concolor) survival in west central Alberta
DownloadSpring 2023
Large carnivores have a significant role in ecosystems and their role as apex predators can have cascading effects that influence ecosystem stability. Managing large carnivores requires an understanding of how they use the land and their vital rates, including survival. For cougars (Puma...

Investigating the Nuclear Roles of Iron Regulatory Protein-1A (IRP1A) in Drosophila melanogaster
DownloadFall 2023
Iron is an indispensable micronutrient for almost all organisms. Either the lack or excess of iron can result in various human diseases. Therefore, to maintain cellular iron homeostasis, the IRP/IRE (iron regulatory protein/iron responsive element) system tightly regulates iron concentrations....

In silico and empirical analyses of the evolution and activity of diverse AB5 toxins found within the Salmonella genus
DownloadFall 2023
Bacterial AB5 toxins are secreted protein complexes composed of an enzymatic A subunit that disrupts host cell functions and a pentameric B subunit that facilitates cellular entry of the toxin by binding to specific cell surface receptors. AB5 toxins are widely recognized for their roles in the...

Bridging the gap between pest control and conservation through effective management of Columbian ground squirrels Urocitellus columbianus in a national park
DownloadFall 2023
Infrastructure development can displace wildlife and lead to human-wildlife conflict, which typically requires non-lethal solutions when it occurs in protected areas. The Columbian ground squirrel (Urocitellus columbianus) is a small burrowing mammal that is prevalent in the mountain parks near...

Synthesis and degradation of polyhydroxybutyrate (PHB) under different nutrient combinations in the alphaproteobacterial methanotroph, Methylocystis sp. Rockwell
DownloadFall 2023
Methane emissions and plastic pollution are two distinct environmental issues that arise from human activities. The ongoing increases in methane emissions and its atmospheric concentration pose a major environmental threat as methane is a potent greenhouse gas, with a warming effect 28 times...

Guanine-Nucleotide Binding Proteins, Tyrosine Kinases, and Associated Regulators in the Integrated Control of Basal and GnRH-Dependent Goldfish Pituitary Hormone Secretion
DownloadFall 2023
In vertebrates, the pituitary gland is a major regulator of physiological processes through the production and release of chemical signal messengers called hormones. In turn, central control of pituitary cell functions is exerted through neurohormones secreted from hypothalamic neurons. The...
