Adaptive variation of trembling aspen in Northwestern Ontario
(2015-08-05)To demonstrate the pattern of adaptive variation of Populus tremuloides (Michx.) to northwestern Ontario climate conditions, a statistical analysis was completed of growth and phenology variables from 26 provenances. ... -
Anatomical and physical wood property variation and juvenile wood distribution in a single stem of trembling aspen
(2003)The variation of fiber length, vessel element length, relative density, ring width and the distribution o f juvenile wood within the stem of a 62-year-old trembling aspen (Populus tremuloides Michx.) were studied. Samples ... -
Biodiversity of ground beetles in young and old poplar stands
(2019)Ground beetles (Coleoptera: Carabidae) are a useful bioindicator group in forests in almost every part of the world. This thesis studied the biodiversity of carabid beetles in old and young age trembling aspen (Populus ... -
Ecologically-based taper equations for major tree species in Manitoba
(2004)Kozak's variable exponent taper equation was fitted for balsam poplar (Populus balsamifera L.), trembling aspen (Populus tremuloides Michx.), white spruce (Picea glauca (Moench) Voss), black spruce (Picea mariana (Mill.) ... -
Genetic variation in physiology and growth under ambient and elevated CO2 concentrations in four provenances of Populus tremuloides from Northwestern Ontario
(2003)Trembling aspen (Populus tremuloides Michx.) is the most widely distributed and probably most genetically varied woody species in North America. Four provenances of trembling aspen seedlings from northwestern Ontario ... -
Glyphosate herbicide for the control of aspen in a white spruce plantation in Manitoba / by F. Wayne Bell
(1989)Three experimental herbicide trials were established within a white spruce plantation located in the Porcupine Provincial Forest of the Mixedwood Section (B.18a) (Rowe 1972) of western Manitoba. The trials were as ... -
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 ... -
Investigation of an epidemic of balsam poplar leaf blotch miner, Phyllonoricter Nipigon, (Leptidoptera: Gracilleriidae) in Thunder Bay, Ontario
(2019)In the summer of 2018, an outbreak of Phylonorycter nipigon, commonly known as the balsam poplar leaf blotch miner, was identified on the Lakehead University campus in Thunder Bay, Ontario. All balsam poplar and trembling ... -
Quantitative metrics of deadwood decay classes as a function of moisture regime and tree species
(2017)The patterns and rates of decomposition of dead woody debris (DWD) in the boreal ecosystem throughout the wood decay process have been hypothesized to vary across moisture regimes and between species. A fundamental aspect ... -
Small-scale disturbance and vegetation dynamics in trembling aspen dominated forests in northeastern Ontario
(2004)The scientific understanding of boreal forest stand development and vegetation dynamics has been well documented with respect to stand-initiating disturbances; however, the role of subtler disturbance events has received ...
