Assessing the relationships between weather, food limitation and breeding ecology in an Arctic top predatorDownload
A long term project being conducted on a population of Peregrine Falcons (Falco peregrinus) breeding near Rankin Inlet, Nunavut, Canada, has chronicled a steady decline in annual productivity over 30 years. By documenting the direct effects of summer rainfall on nestling mortality, a recent study...
Black-tailed prairie dog declines in northwestern Mexico: species-habitat relationships in a changing landscapeDownload
One of the three largest systems of black-tailed prairie dog (BTPD) colonies is located in northwestern Chihuahua, Mexico. During the last two decades, the area occupied by these colonies has been highly reduced and fragmented. Previous studies suggested that agriculture, poisoning, cattle...
Question: Can a wet meadow plant community be established on abandoned peatlands through broadcast plant diaspore spreading in western Canada? Does fertilization impact the development and establishment of the wet meadow? Location: Evansburg, Alberta, Canada Methods: Wet meadow vascular and...
The western toad (Anaxyrus boreas, formerly Bufo boreas) is one of many amphibian species considered to be at risk of extinction (COSEWIC status is Special Concern). I examined habitat use patterns of the western toad using several methods to gain a better understanding of its habitat...
Acorus calamus is an important medicinal plant in many cultures around the world. This plant’s recorded history reaches as far back as 287 BCE, where its main uses were water purification and as a medicinal “cure-all”. In part one, I examined the history of A. calamus, its applications in the...
Species interactions are thought to underlie the stability of ecosystems, and nowhere is studying such interactions more important than the rapidly changing Arctic. The foraging behaviour of generalist consumers is influenced by the abundance of multiple resources, and generalists are thought to...
Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlandsDownload
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...
Sustaining the Recovery of Lake Sturgeon (Acipenser fulvescens) in the North Saskatchewan River of AlbertaDownload
Nearly all Lake Sturgeon (Acipenser fulvescens) populations across North America have experienced losses to historic abundances estimated to be > 99%. This species is especially vulnerable to overharvest, habitat degradation, river fragmentation from dams, and is slow to recover due to life...
The Increasing Prevalence of Smaller Fish in Highly Exploited Fisheries: Concerns, Diagnosis and Management Solutions.Download
A decline in the size of fish within a population is concerning. Large-sized fish are ecologically important and valued for social and economic reasons. Following widespread collapses from angling overharvest, the densities of Walleyes Sander vitreus in Alberta’s lakes increased rapidly with...
In the Rocky Mountain foothills of Alberta, Canada, activities of the forestry and energy sectors have resulted in the installation of tens of thousands of stream-crossing structures. In fifteen Athabasca River basins I found that culverts impeded upstream movements of non-sportfish species...
