Characterization of Soil Spatial Heterogeneity and Improvement of Capping Materials for Oil Sands Mine Reclamation
DownloadFall 2018
Surface mining in the Athabasca Oil Sands Region (AOSR), Alberta, Canada creates a large-scale ecosystem disturbance requiring ‘land reclamation’. Mining approvals require that land reclamation returns the sites to an equivalent land capability class, but this goal has proven challenging to...

Fall 2021
The world’s forests are highly fragmented by linear disturbances, many of which have failed to recover decades after abandonment. Lack of recovery is common, most notably in xeric and hydric forests. Possible mechanisms for this lack of recovery are: life history traits of local species, lack of...

Genetic adaptation of aspen populations to spring risk environments: a novel remote sensing approach
DownloadSpring 2010
This study investigates geographic patterns of genetic variation in aspen spring phenology to understanding how tree population adapts to climatically risk environments. These finding suggest rules to guide seed transfer between regions. I use a classical common garden experiment to reveal...
