Assessing above- and belowground competitive effects in pure and mixed stands of jack pine (Pinus banksiana) and black spruce (Picea mariana)
(2009)Ecological principles of niche, competition and competitive reduction suggest that competition in mixed stands composed of pine and spruce may experience positive interactions through (1) vertical stratification of canopy ... -
Assessment of black spruce portfolio trial survival and growth and implications for reforestation under climate change
(2018)The purpose of this study is to assess the performance of black spruce seedlings at a genetic trial designed to select seed sources adapted to several climate change scenarios. Height variability among trees is attributed ... -
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.) ... -
Effects of soil temperature on a coupled photosynthesis-stomatal conductance model for four boreal tree species
(2000)In order to examine the effects of soil temperature on a coupled photosynthesis-stomatal conductance model, seedlings of trembling aspen (Populus tremuloides Michx), jack pine (Pinsu banksiana Lamb. ), black spruce (Picea ... -
Establishment and early growth of black spruce (Picea mariana [Mill.] B.S.P.) in relation to selected nursery lifting and storage practices / by Roger G. Butson
(1989)Problems associated with the establishment and early growth of overwinter frozen stored black spruce {Picea mariana [Mill.] B.S.P.) seedlings led to research on the effects of selected nursery lifting and storage practices ... -
Mechanical properties (MOE and MOR) of glulam
(2017)Glue-laminated (glulam) timber has strong mechanical properties and is a great building material. It is composed of small diameter wood. There has been a shortage of large dimensional lumber for construction projects. ... -
Modelling the radial and longitudinal variation in wood density and its sensitivity to climate in black spruce (Picea mariana (Mill.) B.S.P.)
(2014-01-22)Wood density variation affects structural timber performance and is correlated with different sources (genetic diversity, stand dynamics and climatic effects) which, to date, have not been comprehensively quantified in ... -
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 ... -
Understory ingrowth mortality model for black spruce (Picea mariana (Mill.) B.S.P.) in mixed species stands of boreal Ontario
(2006)Study area : Longlac area (Northwestern Ontario) -
Varying food quality and its influence on spruce budworm growth, development, and fecundity
(1995)These studies assess how changing food quality influences spruce budworm, Choristoneura fumiferana (Clem.), in terms of the performance characteristics of survival, development, growth, and fecundity. The components of ...
