The ecological effects of the cleared boundaries of Bruce Peninsula National Park
(University of Waterloo, 2009-11-19)Bruce Peninsula National Park (BPNP) clears a 2 m swath of trees on the boundary in order to make it clear when one is entering the park from any neighbouring land; this in particular aims to protect the park and its ... -
Edge of Field Phosphorus Export via Tile Drainage and Overland Flow from Reduced Tillage Systems in Ontario
(University of Waterloo, 2015-02-17)This study examined the role of tile drainage and overland flow in field-scale phosphorus (P) export from reduced tillage systems, as well as the influence of event type and antecedent conditions on P export during major ... -
The effect of biochar amendment on the health, greenhouse gas emission, and climate change resilience of soil in a temperate agroecosystem
(University of Waterloo, 2019-09-26)Biochar has been a successful soil amendment in tropical agriculture for thousands of years. Biochar’s intrinsic chemical and physical properties benefit agriculture in terms of soil health, environmental pollution, and ... -
The effect of biochar on soil health and greenhouse gas emissions in a conventional temperate agricultural system
(University of Waterloo, 2018-09-10)Biochar has been present in tropical agriculture as a soil amendment for millennia. Its ability to alter soil physical and chemical characteristics has been utilized to improve soil health and crop productivity. The use ... -
Effect of climate change and mining on hydrological connectivity of surficial layers in the Athabasca Oil Sands Region
(Wiley, 2018-09-28)This research analyses the impact of climate change and surface mining activities on the hydrologic connectivity of surficial (soil and geological) layers located in a watershed in the Athabasca Oil Sands Region. Surface ... -
The Effect of Coarse Gravel on Cohesive Sediment Entrapment in an Annular Flume
(University of Waterloo, 2014-03-07)The amount and type of cohesive sediment found in gravel river beds can have important implications for the health of aquatic biota, surface/groundwater interactions and water quality. Due to landscape disturbances in the ... -
Effect of Hydrological Regimes on Groundwater Phosphorus Transfer in a Riparian Wetland
(University of Waterloo, 2007-09-14)Riparian wetlands are important areas for regulating phosphorus (P) transfer in shallow groundwater. Limited knowledge is currently available regarding the effects of hydrological regimes on the transfer process of various ... -
The effect of peat structure on the spatial distribution of biogenic gases within bogs: EFFECT OF PEAT STRUCTURE ON BIOGENIC GAS
(Wiley, 2014-10-30)Northern peatlands are a large source of atmospheric methane (CH4) and both a source and a sink of atmospheric carbon dioxide (CO2). The rate and temporal variability in gas exchanges with peat soils is directly related ... -
Effect of Plant Functional Type on Methane Dynamics in a Restored Minerotrophic Peatland
(Springer, 2017-01)Background and Aims: Peatland methane (CH4) fluxes may vary between plant types; however, in mixed communities, the specific role of each species is difficult to distinguish. The goal of this study was to determine the ... -
Effect of water table drawdown on northern peatland methane dynamics: Implications for climate change
(Wiley, 2004-10-07)As natural sources of methane (CH4), peatlands play an important role in the global carbon cycle. Climate models predict that evapotranspiration will increase under a 2 x CO2 scenario due to increased temperatures leading ... -
The Effectiveness of the Internet as a Marketing Tool in Tourism
(University of Waterloo, 2004)With the ever-increasing number of people accessing the Internet and the recent explosion of e-commerce world wide, there are considerable implications for the tourism industry. Tourism suppliers are investing in the ... -
The effects of Eriophorum vaginatum on N2O fluxes at a restored, extracted peatland
(Elsevier, 2017-09)Restoration of extracted horticultural peatlands commonly includes distribution of vegetation and propagules from 10 nearby undisturbed sites over the recently-exposed surface. The resulting growth includes both mosses and ... -
Effects of Hydroclimatic Drivers and Tillage Practices on Runoff Generation and Phosphorus Losses Through Drainage Tiles from Agricultural Fields with Sandy Loam Soils
(University of Waterloo, 2016-03-21)Effluent from agricultural tile drains has been identified a source of phosphorus (P) to water bodies, contributing to algal blooms and water quality degradation. Reduced till (RT) or no-till are Best Management Practices ... -
Effects of Land Use and Hydrophysical Drivers on Temporal and Spatial Variability of Phosphorus and Nitrate Export in an Agricultural Subwatershed in Southern Ontario, Canada
(University of Waterloo, 2018-01-18)The eutrophication of streams and lakes has been a long recognized problem in North America, particularly in Lake Erie where harmful and nuisance algal blooms have had many deleterious effects on aquatic ecosystems. Non-point ... -
Effects of restoring peatland seismic lines on soil properties in boreal Alberta, Canada
(University of Waterloo, 2021-10-04)Long, linear disturbances called seismic lines have been and continue to be created through the boreal forest in Alberta for petroleum exploration. Restoration of these seismic lines has shown some success but is often ... -
Effects of Tillage and Fertilizer Placement on Subsurface Phosphorus Loss Following Fall Manure Application over the Non-Growing Season
(University of Waterloo, 2020-09-25)Increased phosphorus (P) loadings from agricultural runoff into the Great Lakes can lead to eutrophication, resulting in harmful algal blooms and hypoxic conditions. Many studies have demonstrated that subsurface tile ... -
The effects of water table draw-down on the hydrology of a patterned fen peatland near Quebec City, Quebec, Canada
(University of Waterloo, 2005)Hydrological response to climate change may alter the biogeochemical role that peatlands play in the global climate system, so an understanding of the nature and magnitude of this response is important. Simple hydrological ... -
