I examined trends of fine root biomass and necromass in different mixed- and single-species stands within the central and eastern regions of the North American boreal forest to determine how annual fine root production, ...

Despite the importance of wildlife habitat protection in meeting land use management objectives, criteria for habitat identification are surprisingly amorphous. For example, while much current habitat modeling has tended ...

Epiphytes are important components of the forest ecosystem, but the mechanisms that control epiphyte diversity are not clear. Epiphytes are sensitive to disturbance, but their responses to stand-replacing fire are poorly ...

The Alberta oil sands have caused an economic boom in the Canadian economy in recent years. Identifying the best strategy for vegetation recovery after oil sands extraction is critical to restoring the biodiversity and ...

Tree mortality influences forest structure, composition and ecosystem functions. To assess how recent climate changes affected tree mortality, observational studies conducted in old-growth forests have shown that tree ...

Nutrient resorption (NuR) prior to developmental senescence allows for nutrient conservation in plants, driven primarily by genetics, development stage, climate and soil fertility, and litterfall is the vector for the ...

Changes in atmospheric CO2 concentration ([CO2]) and temperature may influence nutrient resources and how boreal species respond to their environment. The effects of increased [CO2] on plants are generally positive but can ...

In the boreal forest, understory vegetation accounts for the majority of floristic diversity and affects overstory succession and productivity, nutrient cycling, and wildlife habitat. In riparian forests, understory ...

This thesis addresses aspects of indigenous knowledge held by members of the community of Pickerel Narrows, located on Granville Lake, Manitoba as part of a larger community-based heritage research project led by Kevin ...

Woodland caribou (Rangifer tarandus caribou) populations throughout much of the boreal forest have decreased as a result of changes to forest composition, including an increase in moose (Alces alces) and wolf (Canis lupus) ...
