Clearcut logging and acid deposition affect lichens and slugs (lichen consumers). The main research goal of this project is to improve our understanding of clearcutting and acidification impacts on lichens in Nova Scotia. The effects of forest logging on ecological communities may extend beyond the edge of the clearcut into the forest. We will: (i) […]

Many industrial hydroponic growers supplement their greenhouses with additional CO2 to improve crop yields. Elevated levels of CO2 can increase rates of photosynthesis and dry-matter accumulation. Greenhouse operators, therefore, often inject extra CO2 (up to 700-1500 ppm) into the aerial environment to improve their crop yields. However, enhancing CO2 levels in commercial greenhouses can incur […]

This study will investigate the ability of an injectable vaccine to reduce illness and death due to pneumonia in lambs born and raised in a feedlot setting. If the vaccine is effective, it will improve the welfare of the lambs on the farm where the study is conducted, reduce antibiotic usage and costs, and improve […]

Farmland covers 6.8% of the surface area of Canada and hosts 313 species of birds, or 69% of all breeding bird species, and Canadian farmland overlaps with the range of 90% of our species at risk. Aerial insectivores including birds and bats are common in these areas and are declining at an alarming rate. Simplification […]

This project is a cooperative arrangement with Siksika economic development. University of Lethbridge researchers are evaluating a range of economic development options for consideration by Siksika. These options are focussed on renewable energy, sustainability, and food security for the nation, and for economic development to further Nation participating in the Alberta and Canadian economies. Siksika […]

Le bois léger et souple du peuplier faux-tremble lui confère une place de choix dans l’industrie des produits forestiers. Son bois est utilisé pour la fabrication de panneau de grandes particules orientées, de lamibois de haute qualité, et de pâte à papier. C’est aussi le feuillu le plus répandu au Canada et aux États-Unis. Sa […]

Ce projet vise à augmenter les performances environnementales de la production acéricole moderne via deux objectifs, soit dans un premier temps par la conception et l’optimisation d’un système d’évaporation à faible empreinte de GES, puis par l’implantation d’une nouvelle technologie de purification des effluents industriels aqueux issus de la production acéricole. Dans la première portion […]

Rocky reef fish play an important role in marine ecosystems and socially as First Nation Food, Social, and Ceremonial, commercial and recreational food fish. Many species of rocky reef fish are vulnerable to fishing pressure and other human impacts like vessel noise. Multiple species are currently listed as Threatened or Species of Special Concern in […]

The proposed research will evaluate changes to ecosystem composition and configuration from the recent unprecedented outbreak of mountain pine beetle (MPB) in JNP, and use new extended time-series data and innovative spatial assessments to consider how altered and novel disturbances have impacted the historical range of variability (HRV) in the park. The outcomes of this […]

Dr. Potter has recently begun exploring the impact that probiotics (beneficial bacteria found in some food sources such as probiotic yogurt and kefir) have on anxiety and depression. Other researchers have shown that probiotic bacteria exert a significant effect on anxiety and depression-like behaviours in animals. A few studies have extended these findings to humans. […]

Notre projet de recherche consiste à fabriquer des panneaux rigides et transparents pour concevoir un nouveau modèle de serre ”verte” et intelligente adaptée au climat froid du Québec. En collaboration de partenaires industriels, nous recyclerons les plastiques comme le polyéthylène et le poly(métacrylate de méthyle), plus communément appellé plexiglas, à partir de sources fiables et […]
