Using portfolio theory to evaluate the regional deployment of transferring tree seeds under uncertain future climates
(2012-11-10)
In this study, the problem of deploying seed from multiple tree improvement orchards to multiple sites in an environment of uncertain climate change is addressed. A modeling approach is designed and applied with the objective ...
The Fine root dynamics after stand-replacing fire and clearcutting in the boreal forest of central Canada
(2012-11-10)
In boreal forest ecosystems, stand age is a key driver of forest ecosystem productivity, carbon storage/sequestration, and other ecosystem functions. The age-related decline of aboveground productivity is well known in ...
Bottom-up and top-down forces shaping caribou forage availability on the Lake Superior coast
(2013-02-03)
Woodland caribou (Rangifer tarandus) occupying the Lake Superior Coastal distribution, Ontario, exist in three subpopulations with distinct ranges and demographics. In this study, three ranges are analyzed in terms of ...
Physiological and morphological responses of mountain maple (acer spicatum l.) seedlings to light under different carbon dioxide concentrations, soil temperature and soil moisture regimes
(2013-02-01)
Determining the response of mountain maple (Acer spicatum L.) to increases in light is confounded by interaction with other environmental factors. Rising atmospheric carbon dioxide concentrations ([CO2]) and the accompanying ...
Characteristics of connectivity between harvested landscapes and fixed-width riparian buffers
(2013-02-03)
Fixed-width riparian buffers are a common best management policy enforced in forested landscapes on first and higher order streams. These buffer areas are delineated along stream banks in the field, based on the presence ...
Natural resource management and Indigenous food systems in Northern Ontario
(2014-12-16)
The forests and freshwaters of Northern Ontario are complex
socio-ecological systems that have provided opportunities to
sustain local lives, economies, and cultures since time
immemorial. Through nation-to-nation ...
The Influence of site type and harvest intensity on understory composition in boreal Picea mariana (Mill.) B.S.P. forest communities in Northwestern Ontario
(2015-08-05)
Plant diversity and composition in boreal black spruce understory communities was assessed 15 years after the application of three harvest disturbance treatments on loam, sand and peat site types. The study was carried out ...
Charcoal in North American boreal forests: implications for carbon storage and management
(2014-01-22)
Charcoal plays an important role in boreal soil function and carbon storage, and is present in most boreal forest soils as a result of naturally recurring wildfires. Charcoal management has been proposed as a potentially ...
Terrestrial lichen abundance in relation to stand structure and silvicultural history
(2014-01-22)
Terrestrial lichen has been identified as an important factor contributing to suitable woodland caribou (Rangifer tarandus caribou) winter habitat. Conservation efforts to maintain viable populations of woodland caribou ...
Habitat use by woodland caribou in a managed boreal forest landscape
(2012-11-10)
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) ...
