Understanding the process of innovation through the theories of learning and communication
Literature on learning, communication, psychology, sociology and related disciplines was reviewed. It was found that innovation is often incorrectly described in the literature as two separate processes. These are the ...
Spruce budworm (Choristoneura fumiferana Clem.) late-instar dispersal and impact on host-species natural regeneration in a boreal mixedwood forest of Ontario
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
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 ...
Effects of harvest treatments on spruce budworm, Choristoneura fumiferana (Clem.) (lepidoptera: Tortricidae), dispersal within forest stands
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)
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 ...
Plantation establishment following chemical site preparation with triclopyr and plantation release with triclopyr-glyphosate herbicide mixtures
Two field studies were conducted to evaluate the use of Release™ (triclopyr ester) for chemical site preparation and its use in mixture with glyphosate for jack pine (Pinus banksiana Lamb.) plantation release.
Natural decay resistance of some Ghanaian timbers and wood decay hazard potential for Ghana
The natural decay resistance of 30 Ghanaian wood species, the decay capacity of four wood decay fungi, the effect of test method on fungal decay ability, and the wood decay hazard potential in Ghana were determined. Five ...
Silviculture, growth and yield of neem (Azadirachta indica A. Juss.) plantations in northern Ghana
The silviculture and growth and yield of neem (Azadirachta indica A. Juss.) grown in individual and community plantations in the Tamale Forest District of Northern Ghana was investigated in 1995. Owing to rising populations ...
