Fall 2017
Multiple novel and rapidly changing environmental factors (i.e. anthropogenic stressors) are increasingly affecting ecological communities, and their functional roles in ecosystems. Consequently, freshwater biodiversity has declined worldwide; however, the functional impacts of this loss should...

Rangelands, a natural ecosystem widespread in Canada, are an important source of land for animal production. Around 26 million ha of rangelands are utilized for beef production and in Alberta, this ecosystem accounts for 6.6 million ha which provides up to 50% of total forage for livestock. To...

Sustaining the Recovery of Lake Sturgeon (Acipenser fulvescens) in the North Saskatchewan River of Alberta
DownloadSpring 2016
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...

Temperature Extremes Exposure and Children’s Health: Extreme Heat- and Cold-Related Impacts in Edmonton, Alberta
DownloadSpring 2024
In the current context of escalating climate change effects on public health, Canada's distinctive geographic position causes it to warm at double the global average rate. This phenomenon leads to potentially heightened health risks for its residents through direct and indirect mechanisms....

Temperature-dependent Allee effects in a stage-structured model for Bythotrephes establishment
Download2011-01-01
Young, J. D., Yan, N. D., Lewis, Mark A., Wittmann, M. J.
Whether the invasive freshwater cladoceran Bythotrephes longimanus can establish after introduction into a water body depends on several biotic and abiotic factors. Among these, water temperature is important because both development rates and mode of reproduction (parthenogenetic or sexual) in...

Climate change is currently a central problem in ecology, with far-reaching effects on species that may be diffcult to quantify. Ectothermic species which rely on environmental cues to complete successive stages of their life history are especially sensitive to temperature changes and so are good...
