Research Interests:

My research project focuses on water transport in trees and is 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 holistic canopy resolutions.  My research has five main objectives:

Objective 1.  Determine spatial variability and the effects of community structure and composition on transpiration rates of four stands of a fire chronosequence between well- and poorly drained sites.

Objective 2.  Examine root xylem anatomy and vulnerability in well- and poorly-drained sites and determine the effects of peat soil characteristics on root hydraulic properties.

Objective 3.  Conduct isotope analysis to determine past effects of plant stress and to understand the impacts of stomatal conductance on carbon uptake.

Objective 4. Conduct remote sensing analysis to distinguish between well- and poorly-drained areas in each stand age and relate image spatial autocorrelation to ground-based measurements.

Objective 5.  Compare spatial and temporal variability of water flux to determine if diurnal and seasonal fluctuations of water budgets change the spatial autocorrelation within a site.
