Heritage Breeds of Livestock in Protected Forest Landscapes: an approach to conserving natural and agricultural diversity
(2012-11-10)
In landscapes with a long history of traditional agricultural activity, some protected areas
are using heritage breeds of livestock to conserve disturbance-dependent habitats and
combat the loss of natural and agricultural ...
Using a novel methodology to test whether group size affects foraging behaviour in elk
(2012-11-10)
Group formation is one of the most striking patterns in the natural world.
Elk (Cervus elaphus and C. canadensis) are well known for their social and gregarious nature, but motivations for this behaviour are not fully ...
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 ...
Investigating productivity and foliar nutrient status in second growth white spruce (Picea glauca) and trembling aspen (Populus tremuloides)
(2012-11-10)
This thesis synthesizes two related papers investigating competitive interactions of second growth white spruce (Picea glauca [Moench] Voss) and trembling aspen (Populus tremuloides Michx.) at the Fallingsnow Ecosystem ...
Bio based phenolic resins and adhesives derived from forestry residues wastes and lignin
(2012-11-10)
The work presented here aims to produce bio-phenolic compounds from forestry biomass (residues, wastes and lignin), and substitute petroleum-based phenol with the bio-phenolic compounds to produce high quality bio-based ...
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 ...
Growth and photosynthetic responses of white spruce seedlings to levels of trembling aspen and red raspberry cover
(2012-11-10)
The effect of competitve species upon crop tree regeneration and growth continues to receive attention from researchers due to the importance of the outcomes. This study stakes a new approach, by examining the combined ...
Predator mediated indirect effects of livestock on native prey
(2012-11-10)
Livestock are common in many protected areas and due to their negative effects pose a considerable challenge to protected area managers attempting to conserve native ecosystems. Negative effects include resource competition ...
A Comparison of beaver foraging behaviour in two national parks
(2012-11-10)
Strategies adopted by foraging herbivores are influenced by the availability of resources. Beavers (Castor canadensis) are important ecosystem engineers, having the ability to modify the landscape through the consumption ...
Characterization of rooting patterns in mixedwood forests of white spruce and trembling aspen: Is competition reduced belowground?
(2012-11-10)
This study examined the rooting patterns of white spruce (Sw, Picea glauca (Moench) Voss) and trembling aspen (Pt, Populus tremuloides Michx.), and the effect of stand type upon such patterns. Specifically, contrasts were ...
