Fall 2021
The warm vaporized solvent injection process has been proposed as a more environmentally friendly alternative to steam-based technologies for bitumen recovery. The process typically involves injecting heated solvent vapor into a horizontal injector; the solvent condenses and dissolves into...

Fall 2016
The increasing anthropogenic pressure on biodiversity in the tropics is resulting in changes to ecosystem structure and increasing species extinction rates (Collen et al. 2013). These issues are heightened in the tropics where 50% of the world’s biodiversity is held in 7% of the world’s...

Fall 2012
In this study, growth of seven hybrid poplar clones and one pure poplar clone was investigated in relation to leaf, shoot, and root physiology under field conditions. Clones included: Walker (24 - P. deltoides x P. xpetrowskyana), Assiniboine (25 - open pollinated Walker cv. Assiniboine),...

Fall 2023
The calving transition is a challenging period for dairy cows characterized by negative energy balance, metabolic dysfunction, and inflammation, each of which may compromise milk production. Despite extensive research in this area, much is still unknown on how to best manage this period. The...

Respiration, Acid/Base, Ammonia and Ionoregulatory Strategies in the Pacific hagfish (Eptatretus stoutii)
DownloadFall 2016
Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...

Responses to lowered salinity in the Pacific spiny dogfish, Squalus suckleyi, a marginally euryhaline shark
DownloadFall 2018
Euryhalinity is the ability to survive in multiple environmental salinities. Full euryhalinity is rare within the elasmobranchs (rays, skates, and sharks), however, marginal euryhalinity is comparatively more common. The physiology underlying these adaptations is relatively understudied in...

Spring 2011
This study examines the effects of Pseudomonas aeruginosa (PAO1) biofilm, with a concentration of cells similar to that reported for saturated aquifers, on the transport of poly(acrylic acid) stabilized nanoscale zero valent iron (pnZVI) in 14 cm long, saturated, laboratory packed columns, with...

Toxicological Characterization of Hydraulic Fracturing Flowback and Produced Water Exposures to Aquatic Organisms
DownloadFall 2021
Hydraulic fracturing is an unconventional oil and gas extraction method used to liberate oil and gas reserves from low permeability geological formations by injecting large quantities of fracturing fluid into the well-bore under high pressures. A by-product of this process is flowback and...

Tree population responses to extreme climate events to guide reforestation under climate change
DownloadSpring 2018
As climates warm and extreme climatic events occur with more frequency and severity, maintaining forest health and productivity may involve planting seed sources from warmer, drier areas. To guide such reforestation strategies, this work analyzes the risks of both climate change and assisted...
