Genetic variation in height and diameter of tamarack (Larix Laricina) and their correlation with syllepsis
(1997)
The broad sense heritability of total height, annual height increment, diameter, volume index
and syllepsis of II provenances of tamarack in northwestern Ontario were examined. Genetic and
Pearson Product Moment correlations ...
Spruce budworm (Choristoneura fumiferana Clem.) late-instar dispersal and impact on host-species natural regeneration in a boreal mixedwood forest of Ontario
(1996)
Understory feeding by the spruce budworm ( Choristoneura fumiferana
Clem.) has potential to alter the species composition of established regeneration
and therefore the value of the future forest. This study sets out to ...
Assessment of land cover changes and hydrologic response of Tamne River Basin
(1996)
Northeastern Ghana, West Africa, is characterised by a high population growth rate and adverse
climatic conditions, e.g., a long dry season followed by a short-duration but intense rainfall
pattern. Land degradation in ...
Participatory action research as a tool for community development : experiences from Northwestern Ghana
(1998)
This study reports on a community development project conducted in Charia, a small village
in northwestern Ghana. The primary intent of the study was to field-test the participatory action
research approach of actively ...
Effects of harvest treatments on spruce budworm, Choristoneura fumiferana (Clem.) (lepidoptera: Tortricidae), dispersal within forest stands
(1996)
Dispersal is a critical trait during the life history of
the spruce budworm, Choristoneura fumiferana (Clem.), which
leads to its widespread infestation and damage. Budworm
dispersal study is of importance for protecting ...
Genetic variation of wood properties in tamarack (Larix laricina (Du Roi) K. Koch)
(1996)
Genetic variation of tracheid length, specific gravity, latewood percentage,
height growth, and ring width among and within four provenances of tamarack (Larix
laricina (Du Roi) K. Koch) was investigated in a ten-year-old ...
Stem wood structure of four Ghanaian Khaya species
(1997)
Four closely related Ghanaian Khaya woods were studied for differences in
anatomical, chemical and physical properties to enable clear identification o f the species. The species were Khaya cmthotheca (Ka), Khaya ivorensis ...
Analysis of hierarchical characteristics of landscapes in Ontario : detecting emergent levels of organizaton
(1998)
Hierarchy theory suggests that complex systems such as ecosystems will develop
hierarchical structure that can be reflected in multiple emergent levels of organization in
landscape patterning. Emergent levels of organization ...
Impact of alternative harvesting practices on the small mammal community in an Ontario boreal mixedwood forest
(1997)
During the current project four studies were conducted to determine the effect of alternative
silvicultural systems, and harvesting methods on the small mammal community of a boreal
mixedwood forest in northern Ontario. ...
Relating genecological variation in white spruce to ecological land classification in Central Canada
(2009)
Genetic diversity can be seen as a fundamental element in forest sustainability. Information about the genetics of trees can be obtained from provenance studies. Previous research has demonstrated that white spruce exhibits ...
