Enhanced prediction of extreme fire weather conditions in spring using the Hot-Dry-Windy Index in Alberta, Canada
DownloadSpring 2023
Fire weather indices used to forecast fire behaviour provide valuable information for wildland fire prevention, preparedness, and suppression. The primary index used in Canada, the Fire Weather Index System, provides qualitative fuel moisture and fire behaviour indices. However, the indices used...

The seasonality of non-structural carbohydrates in mature boreal Betula papyrifera and potential constraints in their remobilization
DownloadSpring 2023
Assimilated non-structural carbohydrates (NSC) can be stored as reserves in plants and remobilized during periods of asynchrony between carbon acquisition and carbon demand to fuel essential metabolic functions and growth. However, the framework of NSC allocation to reserves and their...

Political Governance, Socioeconomics, and Weather Influence Greenhouse Gas Emissions across Subnational Jurisdictions in Canada
DownloadSpring 2023
The drastic and immediate reduction of global greenhouse gases (GHG) is vital if humanity is to avoid the moderate to severe effects of a changing climate. To successfully lower these emissions, it is necessary to integrate and harmonize GHG reduction policies across horizontal and vertical...

Exploring how soil fungi can be used to restore native trees on reclaimed substrates containing petroleum hydrocarbons
DownloadSpring 2023
As part of reclaiming landscapes mined for bitumen, ecosystems must be revegetated to restore self-sustaining ecosystems in the boreal forest of western Canada. Current reclamation practices can involve the construction of large landforms, sometimes from overburden containing up to 8%...

Bottom-up controls of flammability in the Canadian boreal forest at multiple temporal and spatial scales
DownloadFall 2023
Wildfires are the most common disturbances occurring in the Canadian boreal forests. Their incidence and characteristics are controlled by different factors at different temporal and spatial scales. At every scale, vegetation is an essential factor fueling fires. Despite its importance, some...

Patterns of stream temperature and the influence of groundwater in northern Rocky Mountain watersheds
DownloadFall 2023
Stream temperature is an important water quality parameter linked to biotic and abiotic processes that influence the abundance and distribution of aquatic organisms. Stream temperatures can be highly variable through space and time and are determined by energy flux processes. Key energy flux...

Understanding the Role of Secondary Metabolites and Endophytic Fungi in White Spruce Defenses Against Eastern Spruce Budworm
DownloadFall 2023
As a boreal tree species, white spruce (Picea glauca Moench Voss) is under a constant threat by outbreaks of defoliators (foliar feeders) including eastern spruce budworm (Choristoneura fumiferana). Historically, applications of biological insecticides and silvicultural treatments have been used...

Window of opportunity: examining gray wolf (Canis lupus) diets and seasonal patterns of predation on wood bison (Bison bison athabascae)
DownloadFall 2023
Prey selection by predators is a complex process, with acquisition strategies varying between generalists and specialists. However, generalist predators like wolves (Canis lupus Linnaeus, 1758), can select prey in response to increases in abundance or vulnerability of the prey, often influenced...

Consequences of peatland disturbance for dissolved organic matter and nutrient transport and fate in northern catchments
DownloadFall 2023
Northern peatlands contain ~415 Pg of carbon (C) in soil organic matter and are significant sources of dissolved organic matter (DOM) in inland waters. DOM includes a range of molecules that are C-rich and may also contain nitrogen (N) and phosphorus (P). The escalating disturbance of peatlands...
