A comparison of the quality of farm and forest soils in the Emo-Rainy River District of Northwestern Ontario
(2020)
This thesis explores different aspects of the qualities of soils found in a farmer’s hayfield and nearby forested areas on the West side of Emo, Ontario. Soil qualities of a forest and hayfield sites with multiple plots ...
A review of the biological significance of coarse woody debris in forest ecosystems and its positive impact on forest characteristics
(2020)
Coarse Woody Debris (CWD) is considered any woody decay that has fallen on the forest floor. This important piece of forest ecology has a large influence on a variety of forest characteristics. This thesis first evaluates ...
Optimal black spruce seed sources for anticipated future climates
(2020)
Climate change is occurring at an increasingly rapid pace. Many tree species,
even those with wide seed dispersal and high genetic variability, are long-lived
and unable to “keep pace” with these shifting climates. The ...
