Effects of manual, mechanical, and aerial herbicide conifer release on songbird numbers in regenerating spruce plantations in Northwestern Ontario
(1997)This study examined the effects of conifer release with herbicides [Vision® (glyphosate) ], [Release® (triclopyr) ] , and proposed alternatives to herbicides with manual brush saws and mechanical brushsaws, on breeding ... -
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 ... -

(1988)The purpose of this study was to examine the effects of mental imagery in practice and in competition on the free throw shooting performance of basketball players. The subjects were 3 male university caliber basketball ... -
Effects of misinformation on children's recall : the potential for a "buffering" effect in drawing
(2003)Kindergarten children participated in a magic show and then responded to direct questioning about the details. The children were then asked to draw (N = 52) or tell (N = 56) about their favorite part of the show. Two ... -
The effects of moderate exercise on cognitive, cervical, and vestibulo-ocular functioning in healthy individuals: a pilot study
(2018)While cognitive and physical rest have long been the protocol that most physicians have recommended for concussions, there has been an increase in interest with regards to the prescription of low intensity symptom-limited ... -
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 naturally-derived plant compounds on pseudomonas aeruginosa pathogenicity
(2014-12-12)Pseudomonas aeruginosa has risen as one of the most resistant bacterial pathogens affecting people worldwide. Inefficacy of current antimicrobial treatments to relieve P. aeruginosa infections demands the need for novel ... -

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 nitrogen supply on the physiological and morphological responses to elevated [CO2] in yellow birch (Betula alleghaniensis Britt.)
(2023)Ongoing climate changes can substantially impact soil nitrogen availability through its effects on other environmental conditions such as temperature, precipitation, and the frequency and intensity of extreme whether ... -
Effects of nutrient supply, soil temperature and root interactions on morphology, growth, biomass and physiological responses of black spruce and white spruce seedlings to CO2 elevation
(2012-11-10)Changes in atmospheric CO2 concentration ([CO2]) and temperature may influence nutrient resources and how boreal species respond to their environment. The effects of increased [CO2] on plants are generally positive but can ... -
