Drought and defoliation-induced alterations to the structure and function of the vascular tissue in trees
DownloadSpring 2019
Observations of tree dieback and mortality from climate change-induced drought has been documented across the world, however the mechanisms of tree mortality are not fully understood. Infestations of insect pests may also contribute to the process of drought-induced dieback. Tree physiological...

Ecosystem sensitivity to variation in precipitation and defoliation across grasslands of Alberta
DownloadSpring 2022
Climate models project a greater likelihood of increases in precipitation variability and droughts over the Great Plains of North America. Drought’s interactions with other co-occurring factors, such as grazing, can lead to substantial and long-lasting changes to ecosystem goods and services. In...

Effect of drought and defoliation on plant growth, symbiotic nitrogen fixation, soil nitrogen availability and soil microbial dynamics in forage legumes
DownloadSpring 2024
Forage legumes play a crucial role in agriculture due to their symbiotic nitrogen fixation (SNF) ability by forming a symbiotic relationship with soil rhizobia, providing high-quality forage to livestock and improving soil health. The changing global climate is predicted to increase the frequency...

Fall 2021
The long-term survival of trees is highly dependent on their ability to acquire, utilize and store resources to endure local environmental conditions and stresses. Although external uptake and internal cycling of essential resources in deciduous trees is largely regulated by seasonal phenology,...
