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 ...
Climate change-associated temporal increase of tree mortality and its consequences in central and western Canadian boreal forests
(2014-01-22)
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 ...
The antifeedant action of climacodon septentrionalis and two species of sphaerobolus to hyphal grazing by the fungus-feeding nematode aphelenchoides sp.
(2012-11-10)
Fungi are ubiquitous in forest ecosystems and are, collectively, a major force in driving nutrient and organic matter availability and cycling. Some saprotrophic and mycorrhizal fungi are characterized by a perennial ...
Effects of KNO3 and NaH2PO4 on lipid synthesis and CaCO3 accumulation in pleurochrysis carterae and newly identified algal shell coccolith structure
(2019)
Due to the limited energy reserves and the increasing demand for energy, a large number of greenhouse gases such as CO2 have been released to the air. Therefore, there is an urgent need to find new sources of energy and ...
Foliar nutrient resorption and litterfall production with stand age, overstory composition, and disturbance origin in boreal forests
(2015-01-13)
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 ...
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 ...
The Root dynamics of mixed and single species stands in the boreal forest of central and eastern Canada
(2010)
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, ...
Using coarse-scale physical lake characteristics to model lake sturgeon (acipenser fulvescens) feeding habitat and their prey
(2012)
Coarse-scale, physical lake characteristics (lake fetch, shoreline exposure, and littoral-zone slope) were investigated as to their ability to predict benthic macroinvertebrate communities and lake sturgeon feeding along ...
