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 ...

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 ...

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 ...

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 ...

Study area : Longlac area (Northwestern Ontario)

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.) ...

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. ...

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 ...

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 ...

Multi-locus enzyme systems were studied in a black spruce {Picea maniana (Mill.) B.S.P.) clonal seed orchard in northwestern Ontario. The embryonic and megagametophytic tissues of each clone were sampled and ...
