Evaluation of tilling and herbicide treatment for control of wild chervil (Anthriscus sylvestris (L.) Hoffm.) in metro Vancouver regional parks
Wild chervil (Anthriscus sylvestris) is an invasive plant and a member of the Carrot family (Apiaceae). This species concerns natural resource managers because it reduces hay forage quality and adversely alters terrestrial ... -
Case study analysis on the impacts of surface water allocations for hydraulic fracturing on surface water availability of the upper Athabasca River
The Duvernay Formation of the Western Canadian Sedimentary Basin underlies portions of the Upper Athabasca Watershed. To access unconventional shale resources in the Duvernay Formation, horizontal drilling and hydraulic ... -
Distribution and bioaccessibility of metals in peri-urban parks – metro Vancouver
Soil samples collected from 15 peri-urban parks in Metro Vancouver were analyzed for total metals, pH, carbon and bioaccessibility to determine the relationship between point source emission and deposition of metals in ... -
Sea surface temperatures as indicators of yearling California sea lion stranding numbers along the California coast
Marine mammal rescue centers around North America respond to calls from the public about animals that have stranded due to illness or injury. Each year financial planning must occur at these centers with little information ... -
Metal Concentrations and Bioaccessibility in Metro Vancouver Urban Parks Soils
Urbanization increases metal emissions through varying anthropogenic activities (fossil fuel combustion). With urban parks being sinks for emissions, this study attempts to determine metal concentrations and bioaccessibility ... -
An investigation into the influence of slope on trail erosion and the effects of trails on plant communities within Garry Oak and associated ecosystems in Mount Douglas Park, Vancouver Island
Urban parks provide refuge for species at risk, and maintain and preserve biodiversity in densely populated settings. Soil erosion on trails, which can have negative impacts on the surrounding plant communities, is a growing ... -
A comparison of microplastics in farmed and wild shellfish near Vancouver Island and potential implications for contaminant transfer to humans
This research compared numbers of microplastics in three species of farmed and wild shellfish collected near Vancouver Island, BC. Species included were blue mussel (Mytilus edulis), Manila clam (Venerupis philippinarum), ... -
Native and exotic tree leaves contributions to formation of different soil organic matter pools
Deforestation around the world contributes to climate change and soil quality loss. The Atlantic Forest in Brazil has been deforested by 93%. Leaf litter from 16 native trees to the Atlantic Forest and Eucalyptus was ... -
Do microplastic residuals in municipal compost bioaccumulate in plant tissue?
Conventional and biodegradable polymers present in residential and commercial organic waste have a propensity to fragment during the composting process. This research explores whether microplastic residuals present in ... -
Estimating pipeline oil spill volumes using environmental site assessment information
When a reportable oil spill occurs, stakeholders expect the responsible party to issue a release volume estimate as part of the mitigation accountability. One method of estimating a spill volume is to use environmental ... -
How does increased and reduced soil organic matter percentages influence the efficiency of controlled release fertilizers? a comparative case study near Turtleford, Saskatchewan.
Nutrient management is integral to profitable agrisystems and maximizing cropping yields, however, excess urea application results in inefficient plant uptake and losses through leaching or volatilization which threaten ... -
Using Carex aquatilis as a biological assessment tool in monitoring salt-impacted Boreal Peatlands
Saline water is produced as a result of extracting hydrocarbons from geological formations and is brought to the surface during the extraction process. Understanding salinity impacts in the Boreal peatlands in Northern ... -
Land use rifts and landscape multifunctionality in Richmond, BC
Interfaces of agricultural land reserve (ALR) and adjacent land uses in Richmond, BC were mapped in Google Earth and characterized based on their structural and multifunctional attributes using multi-criteria approach, ... -
An evaluation of wastewater treatment technologies for the purpose of recirculation in aquaculture facilities with a focus on an unsubmerged bioreactor
As aquaculture continues to grow worldwide, land-based aquaculture facilities can be ideal because a large volume of fish can be produced in a small area. With growth comes the concern of water usage and wastewater management. ... -
Unmanned Aerial System (UAS) and Structure From Motion (SfM) 3-dimensional modeling of intertidal archaeological features in Fulford Harbour, Saltspring Island, British Columbia, Canada.
Clam garden intertidal features were constructed and maintained by First Nations peoples over thousands of years and are identified throughout coastal British Columbia and Alaska. The thesis study site is the Gulf Islands ... -
The quantification of microplastics in intertidal sediments in the Bay of Fundy, Canada
The Bay of Fundy in Atlantic Canada is noted for the world’s highest tides, heights of which reach 15 meters (Percy, 1996; Thurston, 2011). We characterized microplastic concentrations and distribution in this region. ... -
Groundwater treatment technologies used to remove or contain radioactive contaminants found in the leachate plumes from waste storage sites at Chalk River Laboratories : a case study
(2017-05-04)At Chalk River Laboratories (CRL) two remediation technologies are used on one shallow sand trench waste storage area and one abandoned and buried processing plant each containing contaminated groundwater plumes. The ... -
Effects of fertilizer and plant-growth promoting Rhizobacteria on chlorophyll levels and petroleum hydrocarbon degradation during phytoremediation
The objective of this research was to investigate the efficiency of phytoremediation of petroleum hydrocarbon (PHC) contaminated soils in field remediation sites. Two previously isolated strains of plant-growth promoting ... -
Monitoring permafrost degradation rates due to climate change : developing a practical GIS-based method
Peatlands in the Alberta boreal forest are predicted to experience early and severe climate change impacts through permafrost degradation (melting). Permafrost loss and the subsequent release of greenhouse gases are ... -
Investigating a mitigation strategy for acidic sediment conditions in support of First Nation Bivalve restoration initiatives : the effect of shell hash on porewater pH and carbonate saturation states in Burrard Inlet, British Columbia, Canada
Climate change related impacts threaten calcium carbonate dependent species, such as bivalve shellfish. Coastal sediment acidification may have disproportionate effects on bivalves. Shellfish are ecologically, economically, ...
