Water and crop biomass dynamics in a Cassia siamea Lam. and Zea mays L. alley cropping system
(1994)
Alley cropping is a crop production system in which food crops are grown in
the alleys created by hedgerows of selected tree species, preferably legumes.
The objective of this study was to model a Cassia /maize alley ...
Indicators of competition in a Northwestern Ontario jack pine plantation
(1995)
Competition in forestry is discussed as a prelude to the hypothesis that tree seedling
growth is strongly related to that of other vegetation close to it. The hypothesis states that:
a) the relationship is species-dependent; ...
Impacts of storage, season, duration and steaming on physical properties and extractive content of aspen chips
(1995)
An investigation was made into the rates of moisture content, extractives and
basic wood density losses that occur when trembling aspen (Populus tremuloides Michx.) wood
chips are stored during different seasons ...
Effects of forest management, weather, and landscape pattern on furbearer harvests at large-scales
(2003)
Over the past 50 years, Ontario’s forest landscape has changed due to ever increasing
natural resource management. The natural vegetation pattern, forest composition, and the
fire regime have been altered. Maintaining ...
Study of bushbuck (Tragelaphus scriptus) in Mole National Park, Ghana
(2000)
The bushbuck (Tragelaphus scriptus), one of the ungulates occurring in Ghana, has not
been the subject of extensive study. For the species and its habitat to be managed
effectively to meet the needs of the people of Ghana ...
Genetic variation in traits affecting the water relations of balsam poplar along a latitudinal transect in Northwestern Ontario
(1992)
Genetic variation In traits potentially affecting the waterrelations
of balsam poplar (PopuIus balsamifera L.) clones from
four provenances along a transect from northern Wisconsin to
Pickle Lake in northwestern Ontario ...
Site quality evaluation of jack pine in Northern Ontario using site-index curves
(1994)
Jack pine stem analysis data from 383 fully stocked, mature, undisturbed
plots were collected from studies located in four Ontario Ministry of Natural
Resources regions (Northeast, Northern, North Central, Northwestern) ...
Developing and testing the applicability of a decision support system for the planning of juvenile jack pine thinning
(1994)
An investigation was made into the applicability of a model used to assist in
planning the allocation of pre-commercial thinning to juvenile jack pine stands. The
hypothesis of this study was that planning pre-commercial ...
Ground speed : its influence on the direct seeding of jack pine (Pinus banksiana Lamb.) with the Bracke scarifier
(1993)
The effects that ground speed and obstacle height have
upon microsite creation by the Bracke scarifier and upon the
seeding characteristics of the integral seeder were studied.
The study was conducted in a former gravel ...
