Odell, Rosanise

As forested ecosystems are put under compounding stresses due to the effects of climate change and demand for resources, forest managers must develop innovative ways to utilize natural resources in less-impactful ways. In the boreal forests of Alberta, Ecosystem Based Forest Management (EBFM) is...

Wildfire is the dominant stand-renewing disturbance in the northwestern Canadian boreal forest. Fires burn extensive areas in Canada, disturbing an average of 1.96 Mha yr−1, primarily in the boreal zone. Fires generally occur every ~30 – > 200 years in this region, due in part to a lack of fuel...

Natural disturbance emulation is being used in forest management in an attempt to mitigate the negative effects of harvesting on biodiversity. In the western Canadian boreal forest where the predominant large-scale natural disturbance is wildfire, harvests that leave live mature trees behind at...

Local climates have been increasingly recognized in ecological and climatological studies, particularly because anthropogenic climate change poses threats to biodiversity and ecosystems. Local climates exist at scales of meters to up to a few kilometers and are defined by the set of properties...

Plant identification is a fundamental ecological tool. While identifying flowers and leaves is relatively straightforward, identifying roots can be difficult. Here, I expand the use of fluorescent amplified fragment length polymorphisms (FAFLPs) as a tool to identify roots. Using this molecular...

Northern hemisphere evergreen forests assimilate a significant fraction of global atmospheric CO2. Conifers undergo winter-downregulated photosynthetic activity and spring-onset photosynthetic activation. Currently, increased temperatures are leading to shifts in photosynthetic phenology (early...

Soil is an essential component supporting the growth and maintenance of terrestrial ecosystems such as forests, providing anchorage, water, and nutrients. In Canada’s boreal forest landscape, surface soils can differ widely in their chemical and physical conditions, ranging from coarse to fine...

Wildland fires burn millions of hectares annually, releasing a significant amount of carbon into the atmosphere. Wildland fires also produce pyrogenic carbon – thermally-altered biomass that is highly resistant to decay – which accumulates in fire-affected ecosystems over time. Large wildfires,...

Surface mining is an anthropogenic disturbance which significantly alters natural ecosystems, involving the removal of vegetation, top and subsoils, and several metres of overburden material before accessing valuable resources. Forest reclamation efforts following surface mining face several...

Assimilated non-structural carbohydrates (NSC) can be stored as reserves in plants and remobilized during periods of asynchrony between carbon acquisition and carbon demand to fuel essential metabolic functions and growth. However, the framework of NSC allocation to reserves and their...
