Spatial patterns of vegetation and soil fertility along a grazing gradient in a desert steppe in Inner Mongolia, China
DownloadSpring 2010
Spatial heterogeneities of vegetation and soil can strongly affect ecological processes in arid and semi-arid ecosystems. However, little is known about how those spatial patterns respond to grazing intensity in such systems. I studied how grazing intensity affect the spatial patterns of...

Spatial variability and controls on surface water chemistry and quality in a heterogeneous landscape: the Western Boreal Forest
DownloadFall 2018
Alexander Jonathan Frederick Mertens
Shallow lakes are highly abundant in the Canadian Western Boreal Forest (WBF) and provide essential ecosystem functions, water resources, sources of biodiversity and anthropogenic values. Increasing exposure to resource development and climate change are putting these lakes at risk, raising the...

Fall 2015
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...

Spatiotemporal Patterns and Population Characteristics of Harvested Wolverine (Gulo gulo) in Yukon
DownloadSpring 2017
Wolverines (Gulo gulo) are harvested for fur in Yukon, Canada, but little is known about the sustainability of their harvest. In the absence of population data, harvest management relies on harvest data to assess the efficacy of regulations and harvest sustainability. I examined the...

Spring 2020
Human activities are increasingly fragmenting the natural world. A unifying theme in this thesis is understanding the expected diversity within artificially or naturally discrete habitat networks. I start by testing a common expectation regarding the species composition of small habitat patches,...

Spring flowering trends in Alberta, Canada: response to climate change, urban heat island effects, and an evaluation of a citizen science network
DownloadSpring 2013
In documenting biological response to climate change, the Intergovernmental Panel on Climate Change used phenology studies from many parts of the world, but data from high latitudes of North America are scarce. This thesis reports climate trends and corresponding changes in sequential bloom times...
