Fall 2017
Species extinctions are inevitable, irreversible and a time-delayed process that is accelerating due to the warming climate and the loss of habitats worldwide. The most threatened vertebrate group in terrestrial ecosystems is amphibians. In this thesis, I assess potential range shifts and...

Analytical developments in the use of resemblance measures in community ecology and applications to boreal forest Carabidae
DownloadFall 2012
Understanding the factors influencing the distribution of species is one of the main goals of ecology. This thesis presents three contributions to better and more efficiently understand the factors defining the composition of ecological communities. First, I studied the impact of anthropogenic...

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...

Spatial and Temporal Variations in Tree Growth, Mortality, and Biodiversity in Alberta Forests
DownloadSpring 2014
Understanding the spatial and temporal variation of tree demographic rates and biodiversity is essential for predicting the dynamics of forest ecosystems and their responses to changing environments. This thesis contributes to that understanding through modeling the long-term change in tree...
