Community ecology of ants (Hymenoptera: Formicidae) in the central sand hills of Alberta, and a key to the ants of Alberta.
DownloadFall 2012
In this study I examined ant biodiversity in Alberta. Over a two-year period, 41,791 ants were captured in pitfall traps on five sand hills in central Alberta and one adjacent aspen parkland community. Using additional collections, I produced a key to the 92 species of ants known from Alberta,...

Composition and structure of spider assemblages in layers of the mixedwood boreal forest after variable retention harvest
DownloadFall 2011
Natural disturbances are important drivers of ecosystem change in the boreal forest and new approaches to sustainable forest management draw on natural disturbance patterns as a template for harvesting. The main premise for such approach is that species have evolved and adapted to stand-replacing...

Whitebark pine (Pinus albicaulis Engelmann), a tree species of high elevation forests in western North America, is listed as an endangered species in Canada. Prescribed burns have been employed by conservation agencies as a recovery strategy to create open habitats free of competition and to...

Identifying and analyzing spatial and temporal patterns of lightning-ignited wildfires in Western Canada from 1981-2018.
DownloadSpring 2021
This study looked at the spatial and temporal patterns of lightning-ignited wildfires in Western Canada from 1981 to 2018. Studying patterns of lightning fires over space and time can provide great insight into understanding, highlighting, and quantifying these sequences. This is of great...

Increasing wildfire growth modelling decision support using ensemble weather forecasts over the province of Alberta, Canada
DownloadFall 2015
Across Alberta, wildfires ignite each fire season and a small number achieve a size greater than 100 hectares, which account for the vast majority of the area burned. These fires often require large suppression efforts that include wildfire growth simulation modelling in order to understand their...

Investigating Fire as a Silvicultural Tool for Regeneration of Mountain Pine Beetle-killed Serotinous Pine of Northern Alberta
DownloadSpring 2016
Serotinous pine forests in Western Canada are threatened by a record-breaking mountain pine beetle (Dendroctonus ponderosae; MPB) outbreak - the largest recorded in Western North America. Forest managers are concerned with whether these closed-cone MPB-killed forests will successfully regenerate....

Lightning is widely acknowledged as a major cause of wildland fires in Canada. On average, 250,000 cloud-to-ground lightning strikes occur in Alberta every year. Lightning-caused wildland fires in remote areas have considerably larger suppression costs and a much greater chance of escaping...

Modeling the Impacts of Global Change on Tree Growth and Stand Density of Boreal Forests in Canada
DownloadFall 2022
Abstract Global change of environment and human activity has profoundly impacted boreal forests in structure, dynamics and function, imposing serious challenges for maintaining forest growth and yield in Canada. In this thesis, I address three questions important for understanding and predicting...

In many regions of the world, fires are the primary environmental disturbance producing a mosaic of burned and unburned patches varying at temporal and spatial scales and providing a variety of ecosystem services. Fire perimeters mark the separation between the burned and unburned matrix of a...

The recent open pit mining for oil sands in the Athabasca Oil Sands Region (AOSR), northern Alberta has created an unprecedented industrial scale disturbance whose ecological consequences is not well understood, and requires intensive investigation. This study focused on the temporal dynamics of...
