Stream Crossings in the Western Boreal Forest: Assessing Impacts and Prioritizing Restoration for Native Freshwater Fishes
DownloadFall 2015
Growing anthropogenic development in response to rising demands for natural resources is a major concern for freshwater fish, particularly in resource rich regions such as Canada’s boreal forest. Expanding networks of industrial resource roads has led to the installation of hundreds of thousands...

Effects of Root Zone pH, Calcium and Phosphorus Supply on Selected Boreal Forest Plant Species
DownloadSpring 2015
Soil pH is among the major environmental factors affecting plant growth. In the reclaimed areas following open-pit oil sands mining in northeastern Alberta, Canada, the pH of reclaimed soil is commonly higher than 8.0. The optimum range of soil pH for growth and the tolerance of pH extremes...

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...

Natural Recovery of Upland Boreal Forest Vegetation on a Hummocky Peat-Mineral Mix Substrate in the Athabasca Oil Sands Region, Alberta
DownloadSpring 2010
This research investigated the natural recovery of upland boreal forest vegetation on a peat-mineral mix substrate in the Athabasca Oil Sands Region, Alberta. Three sites, aged 26 to 34 years, were assessed to determine effects of substrate (pH, electrical conductivity, texture), topography,...

Accurate assessment of how animals distribute themselves across the landscape is an essential component of ecological research. Ecologists often conduct surveys to subsample a representative portion of an area of interest and extrapolate their findings to a larger region. Acoustic surveys are...

Information contained within a simple acoustic signal: The fee-bee song of the black-capped chickadee (Poecile atricapillus)
DownloadFall 2015
Black-capped chickadees (Poecile atricapillus) are a common North American songbird that produce numerous types of vocalizations with various functions. The vocal repertoire of black-capped chickadees have been the focus of numerous vocal production and perception studies. Black-capped chickadees...

Predictive Mapping of Yellow Rail (Coturnicops noveboracensis) Density and Abundance in the Western Boreal Forest via Ground and Satellite Remote Sensors
DownloadFall 2019
The Yellow Rail (Coturnicops noveboracensis) is a small, secretive, wetland bird, which is apparently rare throughout most of its range. Almost nothing is known about its abundance and density in the wetlands of the western boreal forest. Emerging technologies have enabled us to effectively...

An investigation of sex differences in acoustic features of the chick-a-dee call of black-capped chickadees (Poecile atricapillus)
DownloadFall 2015
The chick-a-dee call of the black-capped chickadee (Poecile atricapillus) is composed of four main note types (A, B, C, and D) that occur in a fixed order. Sex differences have been identified in a number of black-capped chickadee vocalizations (including tseet calls and fee-bee songs) and in the...

Fall 2018
For male breeding songbirds, song rate varies throughout the breeding season and tends to be correlated with breeding-cycle stages. Although these patterns have been well documented, to our knowledge, this relationship has not been used to predict a bird’s breeding status through acoustic...

The Neural Encoding of Heterospecific Vocalizations in the Avian Pallium: An Ethological Approach
DownloadFall 2011
Songbirds (order Passeriformes, suborder Oscines) have captured the attention of scientists and non-scientists alike with their vocal signals. The black-capped chickadee (genus Poecile) uses its namesake call, chick-a-dee, to convey a variety of information. In Chapter 2 and 3, I examine the...
