Effects of environmental factors on seed germination
(2019)Detailed understanding of the environmental conditions required for the germination and growth of tree seeds is an important prerequisite for the formulation of comprehensive and sustainable forest development strategies, ... -
Effects of forest fire on watershed ecosystem
(2019)Global warming has increased the frequency of forest fires and droughts, which have had a number of effects on the hydrologic ecosystems of watersheds`. Therefore, the influence of forest fires on forest watersheds and ... -
Effects of Lalrise Vita. Bacillus velezensis on Pinus banksiana and Picea mariana
(2022)Jack pine, Pinus banksisana, and black spruce, Picea mariana, are the top two species harvested and planted in the boreal forest of Canada. Sustainable forest management incorporates greenhouses and artificial fertilizers ... -
Effects of mechanical site preparation on the growth of Jack Pine (Pinus banksiana)
(2018)The boreal forest in Canada provides a large volume of timber for Canadians and other countries year after year and effective silviculture is the key to sustainable harvesting. Site preparation can be a critical step in ... -
The effects of mechanical site preparation, unscarified and refill land types on the growth and establishment of planted seedlings
(2023)This study examines the effects of different site types of tree planting blocks on the growth and establishment of planted seedlings within the Black Spruce Forest, north of Thunder Bay, Ontario. Measurements of planted ... -
The effects of nanosilver on northern pike
(2018)Nanosilver (nAg) is an effective anti-microbial agent that is being increasingly used in consumer products. With such an expansive list of products incorporating nAg, the risk of environmental release is high. Studies ... -
The effects of nitrogen Rate On seedlings growth in Picea Mariana
(2017)Nitrogen (N) is critically important for plant growth and development. The objective of this thesis is to examine how different rates of Nitrogen affect the seedling growth in black spruce (Picea mariana Mill.). This ... -
Effects of past grazing and trampling on soil nutrients at Stanley Hill Bison, Kakabeka Falls, Ontario
(2020)Global studies indicate that ungulates can have negative influences on soil quality and directly affect soil nutrient availability. This thesis examines the effects of past cattle grazing and current bison grazing on ... -
The effects of plantation spacing on Pinus resinosa wood density variation and managing for increased carbon sequestration
(2020)Pinus resinosa is found throughout a large portion of eastern North America. Dating back to the early settlement era, wood utilization has varied from solely infrastructure to bioenergy and carbon sequestration. Although ... -
Effects of road construction cost in determining whether a block should be harvested in the summer or winter on the Romeo Malette Forest
(2022)Permanent and temporary forest roads are key infrastructures for the removal of raw forest products. Ensuring an efficient road network is laid out and proper construction methods are chosen will aid in reducing the total ... -
Effects of soil microorganisms on bamboo (Phyllostachys praecon C. D. Chu et C. S. Chao 'Prevernalis) growth
(2021)Soil microorganisms and plants together form a stable dynamic system in which they interact and influence each other. The growth and development of plants provide nutrients to the soil microorganisms, which in turn promote ... -
Effects of species composition and season change on fine root length increase with stand development in Northwest Ontario
(2018)The root length is an important indicator to reflect the growth characteristics of the tree, but the root length is difficult to obtain through direct measurement, and the root as a sensitive organ of plants can indirectly ... -
Effects of species mixtures on fine root production in a young boreal forest
(2019)1. Fine roots (< 2 mm) play a key role in terrestrial ecosystem processes. Species diversity loss has been recognized as one of the primary global change drivers that can have profound negative effects on ecosystem ... -
The effects of stratification methods on paper birch and yellow birch seed germination
(2022)This study examines the use of both a typical cold moist stratification method, and an alternative in their ability to affect germination rates in paper birch (Betula papyrifera) and yellow birch (Betula alleghaniensis). ... -
Effects of the nitrogen deposition on the forest ecosystems: an overview
(2023)Human activities exacerbate the production and emission of reactive nitrogen and lead to the increase and globalization of nitrogen deposition. At present, the interference of human activities in the global nitrogen cycle ... -
The effects of the Red 003 Fire on woodland caribou (Rangifer tarandus caribou) habitat in the Sydney Range
Disturbances, including forest fires, are considered a primary driver of population decline in boreal woodland caribou populations across Canada. The Sydney Range in northwestern Ontario has been assessed as not self-sustaining ... -
Efficacy of MYKE® on in vitro growth of American elm (Ulmus americana)
(2017)This thesis is an examination of the commercial product MYKE which is a perlite-peat mixture containing 7 spores/g of Glomus intraradices N.C Schenk & G.S. Sm., a vesicular-arbuscular mycorrhiza-forming fungus. Seeds of ... -
eFRI and Growth & Yield in Ontario: A Literature Review
(2018)The forests of Ontario are a vast resource owned by the Crown that has been subjected to many methods of forest management since the beginning of Ontario as a province. The forest resource was thought of as inexhaustible ... -
Estimating change of amphibian wetland habitat for Painted Rock Island, Lake of the Woods, from 1952-2015 using historical aerial photography and modern satellite imagery
(2020)Amphibians are suffering from global decline due to a synergy of factors – many of which are primarily the result of anthropogenic impacts including climate change, yet they are a crucial component of a functioning ecosystem. ... -
Estimating tanager densities in chakra agroforests in relation to plant species diversity and area of chakra
(2019)Chakra agroforests in the community of Verde Sumaco, Ecuador were surveyed to estimate tanager densities. Distance sampling using transects was the methodology used to record presence of tanager species. Using the data ...
