Avian communication networks: how audible are mountain chickadee males during dawn signalling?
My thesis investigates how urban noise influences the relative audibility of songs to female Mountain Chickadees (Poecile gambeli), who assess male signalling at dawn while roosting within the nest cavity. Over two breeding seasons, I monitored…

Pacific marten (Martes caurina) as an apex predator : the habitat and diet ecology of an insular population of mesocarnivore on Haida Gwaii
Pacific marten (Martes caurina) may benefit from invasive or non-native species that occur across some coastal areas of the Pacific Northwest. I used remote-camera trapping and stable-isotopes of carbon and nitrogen to infer resource-use strategies…

Persistence of glyphosate, and associated influence on available nutrients, in native plant tissues following sublethal herbicide application in northern British Columbia forests
Glyphosate-based herbicides (GBH) are highly effective, nonselective herbicides that have been used in British Columbia’s forest industry since the early 1980s to remove deciduous vegetation competing with commercially important coniferous tree…
Homing, redd site characteristics and the effect of dissolved oxygen on development of larval coho salmon

Homing, redd site characteristics and the effect of dissolved oxygen on development of larval coho salmon
Life histories of Pacific salmon are remarkable in that they return to specific freshwater sites to spawn after multiple years of ocean residence. In Chapter 1, I investigated site fidelity at a reach scale for Interior Fraser Coho Salmon (…

Linking spatial stream network modeling and telemetry data to investigate thermal habitat use by adult arctic grayling
River networks have a high amount of thermal habitat heterogeneity which is a critical abiotic factor driving freshwater fish distribution. The fitness repercussions of residing outside a species’ optimal thermal limits, and the resulting…

Ground beetles (coleoptera: carabidae) of the Chun T'oh Whudujut Park in eastern British Columbia, Canada, and their use as bioindicators of disturbance
The Chun T’Oh Wudujut is a provincial park located in the Interior Cedar-Hemlock biogeoclimatic zone. My objective was to assess the use of carabid beetles as bioindicators of change in this unique interior temperate rain forest ecosystem. Using a…
Effects of changing environmental conditions on glyphosate degradation and melatonin production in wild strawberries

Effects of changing environmental conditions on glyphosate degradation and melatonin production in wild strawberries
Glyphosate is a broad-spectrum herbicide commonly used in Canadian forests to control competitive vegetation. The non target plant species are exposed to a sublethal dose of glyphosate-based herbicides (GBH) due to aerial applications that cause…

Piloting environmental DNA for fisheries monitoring in the upper Peace River watershed
Applications of environmental DNA (eDNA) represent one of the most significant recent advances in aquatic species monitoring. eDNA has the potential to dramatically increase the effectiveness and efficiency of fisheries monitoring across large…

Fate of hatchery-reared juvenile Nechako white sturgeon (Acipenser transmontanus): Assessment of predation by river otters (Lontra canadensis)
Predation of fish raised and released as part of conservation aquaculture programs can pose a threat to the recovery of endangered populations. Therefore, understanding the impact of specific predators is important to inform these programs. In…
