Assessing operational silviculture and modeling juvenile growth in Saskatchewan white spruce (Picea glauca (Moench) Voss) plantations
DownloadFall 2015
White spruce (Picea glauca (Moench) Voss) plantations are often established with mechanical site preparation and tending. These silvicultural treatments encourage plantation survival and can influence growth, composition, and yield. To assess operational silviculture and model managed stand...

Assessing the effects of non-native salmonids on Bull Trout (Salvelinus confluentus) in Alberta’s Rocky Mountain Foothills
DownloadFall 2022
The rapid decline in global biodiversity threatens the natural resources, food security, health, and livelihoods of current and future generations. Anthropogenic activities, including the introduction of non-native species, habitat fragmentation and alteration, and resource extraction, have...

Assessing the impacts of multiple ecological stressors on an endangered native salmonid, the Athabasca Rainbow Trout, in the foothills of the Canadian Rocky Mountains
DownloadFall 2018
Freshwater fish face a multitude of ecological stressors, which has resulted in substantial declines in aquatic biodiversity. The loss of aquatic biodiversity can lead to changes in ecosystem function, productivity and food web dynamics. One such imperiled freshwater fish is the Athabasca Rainbow...

Assessing the long-term impact of acid deposition and the risk of soil acidification in boreal forests in the Athabasca oil sands region in Alberta, Canada
DownloadFall 2012
Significant amounts of SO2 and NOx have been emitted from the Athabasca oil sands region (AOSR) in Alberta, Canada, in the past several decades. The impact of acid deposition on forest ecosystems and the risk of soil acidification were assessed in jack pine (Pinus banksiana) and trembling aspen...

Assessing the Potential for Hybrid Vigour Within a Species: Disparate Population Breeding of Balsam Poplar
DownloadFall 2021
When two or more species are crossed to produce hybrid progeny, some of them can be expected to yield a growth performance far superior to that of either parent (i.e., hybrid vigour/heterosis). To date, there have been few attempts to examine whether hybrid vigour can be achieved by crossing...

Assessing the relationships between weather, food limitation and breeding ecology in an Arctic top predator
DownloadSpring 2016
A long term project being conducted on a population of Peregrine Falcons (Falco peregrinus) breeding near Rankin Inlet, Nunavut, Canada, has chronicled a steady decline in annual productivity over 30 years. By documenting the direct effects of summer rainfall on nestling mortality, a recent study...

Assessing the Short-term Impacts on Sediment Production following Rapid Harvest and Stream Crossing Decommissioning in Rocky Mountain Headwaters
DownloadFall 2017
While rapid road and road-stream crossing decommissioning after forestry operations may serve to limit broader impacts of sedimentation in high value headwater streams, few studies have evaluated the combined effects of accelerated harvest operations and rapid retirement of roads on stream...

Assessing the station holding ability of three benthic fishes exposed to flow augmentation: Implications for a species at risk
DownloadFall 2023
Flow augmentation forces Plains Sucker in the Milk River to adopt more efficient station holding mechanisms, which must be energetically costly as they are not maintained year-round. The station holding ability of Milk River Plains Sucker was measured using a Brett-style swim tunnel respirometer,...

Assessing the vulnerability of rare plants using climate change velocity, habitat connectivity and dispersal ability
DownloadFall 2015
Climate change generally requires species to migrate northward or to higher elevation to maintain constant climate conditions, but migration requirement and migration capacity of individual species can vary greatly. Individual populations of species occupy different positions in the landscape...
