Preliminary investigation of bald eagle distribution, productivity and nest site requirements in Northern Ontario
(1995)
Bald eagles {Haliaeetus leucocephalus alascanus) have been declared an endangered
species in Ontario. For protection of bald eagles from behavioural and habitat
disturbance, their nests are defined as Areas of Concerns ...
The effects of spacing and genetic factors on growth and tree form quality traits of plantation-grown jack pine
(2000)
Overall tree form ofjack pine (Pinus banksiana Lamb.) growing in natural stands
varies from straight slender trees with compact crowns to broad, limby and even multi-stemed
trees. Jack pine grown in plantations at ...
Effects of elevated carbon dioxide concentration and light on biomass morphology and physiology of black spruce and white spruce seedlings
(2008)
Carbon dioxide concentration and light interactions influence competition among boreal tree species, though little is known about the exact effects. The interactive effects of [CO 2 ] and light on growth, biomass production, ...
Adaptive variation in cold hardiness among aspen (Populus tremuloides) provenances
(2002)
The relative efficiencies of using different methods to detect genetic variation in
cold hardiness were evaluated, and the adaptive variation among aspen provenances was
further studied. This thesis is organized as three ...
Black spruce (Picea mariana [Mill.] B.S.P.) boreal ecosystems : how tree-length and full-tree harvesting affects soil microbial populations
(2000)
To evaluate the hypothesis that microbial populations are affected by
organic biomass removals, a study was designed to complement ongoing work in a
black spruce {Picea mariana [Mill.] B.S.P.) Boreal ecosystem. The ...
Photosynthetic efficiency of frozen-stored Picea glauca seedlings in relation to root pruning, root growth, and shoot moisture stress / by S. J. Colombo. --
(1981)
This study examines the influence of duration of frozen
storage (-2 C) and root pruning on photosynthetic efficiency,
shoot moisture stress and root growth of white spruce (Picea
glauca (Moench) Voss) seedlings planted ...
Phenotypic variation in Larix lyallii and relations in the larch genus
(1988)
Larix Iyallii Parl, (alpine larch) is a small to medium tree
restricted to the timberline zone of the mountainous regions
of the Pacific Northwest of the United States and the adjacent
southwest of Canada. To examine ...
Indices of branch contribution to bole growth in Pinus resinosa Ait.
(1982)
The contribution of individual branches to the
current annual xylem increment of the main stem of six
young red pine (Pinus resinosa Ait.) was investigated.
Logical estimates of branch productivity including:
branch ...
Mating system and population structure in a black spruce (Picea mariana (Mill.) B.S.P.) clonal seed orchard in Northwestern Ontario
(1985)
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 ...
Glyphosate herbicide for the control of aspen in a white spruce plantation in Manitoba
(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 ...
