My dissertation focused on water transport in trees located in the boreal forest of northern Manitoba. This area is an important component in global climate change scenarios because of its large land area and ability to sequester and store carbon from the atmosphere. Water fluxes of these ecosystems control carbon budgets and other biogeochemical cycles and are therefore integral to understanding the interaction of physiological processes and their impacts on global change. Development of a wildfire chronosequence in the northern Canadian boreal forest provides an opportunity to study the effects of fire and stand age on water cycles and their implications on global change scenarios. Quantifying the interaction between spatial and temporal variability is important in understanding the variations that occur at a particular study site in order to accurately scale transpiration rates.
My research focuses on quantifying the interactions between spatial and temporal patterns of transpiration, determining the mechanisms driving this variability, and utilizing this information to accurately scale from individual-level measurements to canopy and ecosystem resolutions.
