• Unexpected Connections: Salicinoid Biosynthesis in Poplar 

  Gordon, Harley Oliver William (2022-12-22)

  Populus is a genus distributed across the northern hemisphere. Poplars (Salicaceae) are subject to stresses in their environment such as herbivory, drought, and fire. These perennial hardwoods produce abundant phenylpropanoid ...
• A deep dive into the sablefish (Anoplopoma fimbria) opsin repertoire: insight into melanopsin expression, localization and function in an unlikely demersal model. 

  Barnes, Hayley (2022-09-29)

  Light regulates many biological processes through light-sensitive proteins called opsins. Opsins are involved in vision, but they are also expressed in extraretinal tissue, where their roles are far less clear. Fish have ...
• Assessing the contribution of Red Alder (Alnus rubra) to forest stand nitrogen budgets 

  Nehring, Lise (2022-09-29)

  Red Alder (Alnus rubra) is a native coastal hardwood in British Columbia and has evolved a symbiotic relationship with the nitrogen-fixing actinomycete, Frankia. This research uses δ15N signatures in soils, wood and litter ...
• The mechanism underlying bipolar cell subtype specification 

  Ruiz de Chavez Ginzo, Alberto (2022-09-07)

  The mammalian central nervous system (CNS) has a high degree of complexity and cell type diversity that enables sophisticated processing of sensory information, circuit formation, and behaviour. While much is known about ...
• Nearshore habitat use, estuarine residency, and conservation priorities for Pacific salmon in the Fraser River, British Columbia 

  Chalifour, Lia (2022-05-02)

  Cumulative effects from multiple anthropogenic stressors over the past three centuries have severely impacted estuarine and coastal habitats, with cascading effects on the species that rely upon them. Pacific salmon ...
• CRISPR/Cas9 mutation of MYB134 and MYB115 to study regulation and functions of proanthocyanidins in poplar roots 

  Liu, Yalin (2022-05-02)

  Secondary metabolites play important roles in tree defense. Proanthocyanidins (PAs), one of the most common secondary metabolites, are widely distributed in trees and woody plants, and are abundant in poplar. In my research, ...
• Holocene fire frequency and links to climate and vegetation history on Pender Island, British Columbia, Canada 

  Giuliano, Camille (2022-04-28)

  Contiguous macroscopic charcoal analyses were performed on a 9.03 m long lake sediment core from Roe Lake on Pender Island in the Gulf Islands National Park Reserve of British Columbia, Canada to reconstruct the island’s ...
• Intertidal resource cultivation over millennia structures coastal biodiversity 

  Cox, Kieran D. (2021-12-22)

  Cultivation of marine ecosystems began in the early Holocene and has contributed vital resources to humans over millennia. Several more recent cultivation practices, however, erode biodiversity. Emerging lines of evidence ...
• Impacts of local and global stressors on coral biodiversity 

  Maucieri, Dominique (2021-08-31)

  Global biodiversity losses are being driven by human actions, and coral reef communities are not immune. Local anthropogenic stress and global climate change are rapidly changing coral reefs, through coral bleaching and ...
• Factors influencing the intriguing persistencce of a Wolbachia symbiont in spotted wing Drosophila 

  McPherson, Audrey E. (2021-05-31)

  Wolbachia is a maternally inherited, endosymbiotic bacterium that infects at least 40% of terrestrial arthropods. As a facultative symbiont in the majority of its hosts, Wolbachia commonly act as a reproductive parasite; ...
• Fitness and transmission of a selfish X chromosome in female Drosophila testacea 

  Powell, Candice (2021-05-26)

  Selfish genetic elements break the rules of Mendelian inheritance to bias their transmission to following generations, often with negative fitness consequences. A striking example involves selfish X chromosomes that ...
• Asymmetry in the lateral line of threespine stickleback, Gasterosteus aculeatus: ecology, evolution and behaviour 

  Planidin, Nicholas (2021-05-18)

  Behavioural asymmetry (laterality) is widespread among conspicuously bilaterally symmetrical organisms, playing a part in many aspects of life history from reproduction to feeding. Laterality is typically thought to occur ...
• Microplastics in coastal marine habitats and food webs 

  Covernton, Garth Aidan (2021-05-03)

  Microplastic particles (MPs) are widely distributed in aquatic environments and present a potential risk to marine life. This thesis considers several issues relating to methodologies for sampling and analyzing MPs and the ...
• Application of structure-from-motion photogrammetry to quantify coral reef structural complexity change following a mass mortality event 

  Bruce, Kevin (2021-05-03)

  Hermatypic, or reef-building, corals (Order Scleractinia) are the foundation of coral reefs, providing a diversity of structurally complex habitats for the myriad species in these biologically diverse ecosystems. However, ...
• Examining the influence of depth and tidal current on nearshore fish communities using scientific and citizen science data 

  Campbell, Jillian (2021-04-29)

  Learning about marine ecosystems is challenging; organisms move, abiotic conditions change, underwater environments are difficult to sample, and in BC, the coastline is lengthy and largely remote. This thesis explores two ...
• Differential distribution of co-transmitted cholinergic and GABAergic synaptic inputs onto substantia nigra dopaminergic neurons 

  Le Gratiet, Keyrian Louis (2021-04-28)

  Neuronal communication in the mammalian brain relies on the presynaptic release of neurotransmitters which bind to ligand-gated ion channels found on postsynaptic neurons to modulate neuronal excitability. One such ...
