Irrigated agriculture is an important source of global food supply due to its high production intensity; however, it is also a large user of water and nitrogen fertilizer, and therefore, a potential large contributor of N2O emissions. This study explores the viability of fertigation, a method of...

Ostermann, Deborah K.

The long-term (11 to 12 years) impact of grazing and pipeline right-of-way (ROW) zone on plant community development was assessed in Dry Mixed Grass, Mixed Grass (Milo) and Fescue Grassland (Porcupine Hills) Ecoregions. Native and non-native seed mix influences on plant community development were...

The boreal forest is an ecologically dynamic region with a long history of natural disturbances. These dynamics now run at a different and more rapid pace in Alberta because of land-use change, forestry, and developments in the energy industry. Although boreal owls Aegolius funereus and northern...

Many northern Alberta soils have a thick forest floor that houses the majority of soil biogeochemical processes and biological interactions. Microarthropods dominate the faunal communities in these soils, and oribatid mites are the key detritivores that initiate litter decomposition and maintain...

Peatlands in Canada’s western boreal forest are a major source of dissolved organic carbon (DOC) to downstream ecosystems, where DOC regulates carbon cycling, and can affect ecosystem productivity and habitat quality. Subarctic ecosystems are becoming increasingly vulnerable to the effects of...

Klutsch, Jennifer G.

Tree-infesting organisms have recently expanded their ranges into many novel habitats where they will not only interact with new host tree species, but also with a myriad of other organisms that also share these hosts. Understanding the major factors and mechanisms that mediate...

Changing fire dynamics and increasing global temperatures are causing changes to the fire regime and permafrost stability in the Arctic. Models have separately predicted the widespread thawing of permafrost and increasing magnitude and intensity of wildfires over the next century. However, while...

Research Problem Since the introduction of open pit mining of the Athabasca Bituminous Sands (ABS) in 1967, this industry has generated considerable quantities of mineral dust that when released is injected into the atmosphere and settles in the surrounding environment. Despite this, a full...

The development and application of quantitative soil quality assessment (SQA) concepts involve calibrating soil quality indicators (SQI), such as soil organic carbon (SOC), to soil management goals such as yield or biomass productivity to create soil quality-scoring functions (SQF). Currently,...

The occurrence of pharmaceutical and personal care products (PPCPs) in municipal wastewater treatment plants (WWTP) is an emerging environmental issue. Among other concerns, aquatic invertebrates sampled from WWTP have measurable concentrations of PPCPs, which have been found to cause adverse...
