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 ...
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. ...
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 ...
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 ...
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 ...
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.) ...
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 ...
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 ...
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 ...
The impact of a fungus-feeding nematode (Aphelenchoides sp.) on decomposition of trembling aspen wood by various wood-decay fungi
(2018)
Grazing by fungus feeding invertebrates on fungal mycelium can potentially impact many important ecological processes such as the formation of mycorrhizas and the decomposition of wood and litter. A study was initiated to ...
