Variations in jack pine (Pinus banksiana) monoterpene composition and subsequent effects on pheromone production by mountain pine beetle (Dendroctonus ponderosae)
DownloadSpring 2015
The secondary compounds of pines (Pinus) can strongly affect the physiology, ecology and behaviour of bark beetles (Coleoptera: Curculionidae, Scolytinae) that feed on host sub-cortical tissues. Jack pine (Pinus banksiana) has a wide distribution range in North America and thus variations in its...

Variations in Size and Optical Properties of Dissolved Organic Matter During Mixing at Large River Confluences: Implications for Source Discrimination in the Boreal Zone
DownloadSpring 2021
The functionality of dissolved organic matter (DOM) in natural waters depends on its size and composition. Identifying the sources and associated properties of DOM is vital to understand its effects on downstream ecosystems. River mixing has great potential to alter DOM quality, but its role in...

Vascular Adaptations to Pregnancy in a Rat Model of Advanced Maternal Age: Endoplasmic Reticulum Stress as a Potential Target for Therapeutic Intervention
DownloadSpring 2023
Advanced maternal age (≥35 years) increases the risk of pregnancy-specific complications such as reduced fetal growth and preeclampsia. The Davidge laboratory previously showed poor pregnancy outcomes and vascular dysfunction in a rat model of advanced maternal age. However, vascular adaptations,...

Background: During exercise, there is an increase in sympathetic activity, causing vasoconstriction and reduced blood flow. However, to maintain blood flow and oxygen delivery to the exercising skeletal muscle, a phenomenon known as sympatholysis occurs, which is the reduction in sympathetic...
