Identifying understory diversity and resilience patterns with the depth-to-water index in boreal mixedwood forests
DownloadFall 2017
For the purpose of informing biodiversity conservation efforts in managed landscapes, we explored whether and how understory plant communities (abundance, diversity, composition) were related to a topographic moisture index, called depth-to-water, in the boreal mixedwood forests of northwestern...

Impact of Farming Practices on Soil Bacterial Community Composition, Diversity, and Interactions in the Main Agricultural Regions of Alberta
DownloadSpring 2022
Soil health refers to “the capacity of soil to function as a vital living system”, implying not only the capacity of soil to providing services of human interest, but also its capacity to provide ecological services, which makes ecosystems sustainable for the long term. The assessment of soil...

Impact of Mountain Pine Beetle Attack on Water Balance of Lodgepole Pine Forests in Alberta
DownloadSpring 2013
In recent decades mountain pine beetle (MPB) has become an important natural disturbance agent in western Canada, thus the impact of this disturbance will likely be an important component affecting water resources in this region. Despite the widespread recognition of the potential changes, there...

Impact of seedling characteristics, outplanting time, and container size on early establishment of aspen (Populus tremuloides) on reclamation sites
DownloadFall 2011
Aspen seedlings often suffer from transplant shock after outplanting. The influence of seedling characteristics and time of outplanting (spring, summer and fall) on field performance was examined on mining reclamation sites. Seedling characteristics were modified by inducing premature bud set...

Impacts of a novel predator on aquatic invertebrates in fishless lakes: Implications for conservation translocations
DownloadFall 2018
Fishless mountain lakes hold important ecological and conservation value. As such, managers are establishing conservation goals (e.g., non-native fish removal) to restore the naturalness to many of these lakes. Managers who are recovering native coldwater fish populations threatened by climate...

Impacts of a six year old pipeline right of way on Halimolobos virgata (Nutt.) O.E. Schulz (slender mouse ear cress), native dry mixedgrass prairie uplands, and wetlands
DownloadSpring 2016
Reclamation of native prairie ecosystems is of growing importance as they continue to be impacted by anthropogenic disturbances. Since European settlement, Alberta grasslands have declined by 61 %. Grasslands are agriculturally important, act as a carbon sink, and many species depend upon them....

Impacts of aggregated retention harvesting on the diversity patterns of nocturnal moth species assemblages in the mixedwood boreal forest of northwestern Alberta
DownloadFall 2012
The loss of mature forest habitat from forest harvesting represents a substantial threat to the diversity of nocturnal boreal forest moth assemblages. In this study, I used spatial patterns of species diversity to quantify the effects of aggregated green tree retention harvesting on the diversity...

Impacts of clear-cut harvesting on carabid beetle (Coleoptera: Carabidae) assemblages of aspen dominated forests in central Alberta
DownloadFall 2016
Disturbances, both natural and those related to human activity, reset succession in boreal ecosystems, and affect forest biodiversity. The link between forest harvesting and biodiversity is of considerable conservation concern. In this thesis, I investigate the impacts of clear-cut harvesting on...

IMPACTS OF DISTANCE TO PIPELINE DISTURBANCE ON MIXED GRASS PRAIRIE AND HALIMOLOBOS VIRGATA (NUTT.) O.E. SCHULZ (SLENDER MOUSE EAR CRESS)
DownloadSpring 2014
Halimolobos virgata (slender mouse ear cress) is an at risk plant species in the Dry Mixed Grass Subregion of Southern Alberta. Little is known about effects of disturbances such as pipelines on Halimolobos virgata and its habitat. Environment Canada recommends a non species specific set back of...

Lejoly, Justine Daniele Marthe
Exotic species of earthworms are invading North American forests, where native earthworms were extirpated by the last glaciation. The invasion of these ecosystem engineers can alter soil organic matter (SOM) dynamics, carbon (C) persistence, and ecosystem functioning. While the topic has been...
