Abiotic Stresses to Vegetation Re-establishment in a Cutover Bog Contaminated with Seawater
(University of Waterloo, 2006)Part of a cutover bog in Pokesudie Island, New Brunswick, Canada was contaminated with seawater and was still largely devoid of vegetation 5 years after the event and was consequently chosen for study. The study area ... -
Analyzing the impacts of road construction on the development of a poor fen in Northeastern Alberta, Canada
(University of Waterloo, 2015-05-25)Linear disturbances such as powerline rights of way, seismic lines and roads are common in areas of intensive resource development. Roads that bisect wetlands can alter their hydrologic connectivity on a local or landscape ... -
A changing North: The implications of high-volume groundwater extraction and reduced water availability on sub-arctic peatland hydrology, connectivity, and geochemistry
(University of Waterloo, 2022-07-05)Patterned bog and fen peatlands of the Hudson Bay Lowlands (HBL) currently make up 90% of land cover in this region and form one of the largest continuous peatland complexes in the world. A globally significant storage of ... -
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 ... -
Effects of seismic lines on peatland carbon cycling in boreal Alberta, Canada
(University of Waterloo, 2023-04-21)Peatlands serve as long-term carbon (C) sinks as well as a significant source of methane (CH4) to the atmosphere. Over 134,000 km2 of peatlands are in northern Alberta, a part of the boreal region of Canada where extensive ... -
An evaluation of moisture dynamics and productivity of Sphagnum and Tomenthypnum mosses in western boreal peatlands, Canada
(University of Waterloo, 2014-05-22)Western boreal peatlands have diverse ground covers of Sphagnum and brown mosses that have important hydrological controls on peatland-atmosphere interactions. Since peatland mosses are non-vascular, their shoot structural ... -
The Hydrochemical Fate and Transport of Treated Domestic Wastewater Contaminants During a Wastewater Polishing Experiment in a Sub-Arctic Ladder Fen Peatland
(University of Waterloo, 2016-09-27)Protecting northern aquatic ecosystems is critical to ensuring the sustained use of these environments; however, with increasing industrial and residential development pressures in this region the safe and effective treatment ... -
Hydrologic function of a moderate-rich fen watershed in the Athabasca Oil Sands Region of the Western Boreal Plain, northern Alberta
(Elsevier, 2019-03)Peatlands are a dominant land feature in the Athabasca Oil Sands Region (AOSR) of the Western Boreal Plain (WBP), comprising >50% of the total land area, many of which are moderate-rich fens. The carbon stocks of moderate-rich ... -
The hydrological interactions within a mine impacted peatland, James Bay Lowland, Canada
(University of Waterloo, 2015-08-05)The development of a large open-pit diamond mine in the James Bay Lowland, one of the world’s largest wetland complexes, provides insight into hydrological processes that sustain wetlands in the region. The bog and fen ... -
Impacts of seismic line restoration on CO2, CH4, and biomass
(University of Waterloo, 2021-10-21)Oil and gas exploration has resulted in over 300,000 km of linear disturbances, known as seismic lines, throughout boreal peatlands across Canada. Sites are left with altered hydrologic and topographic conditions that ... -
Saturated and vadose zone fate and transport of a continuously released tracer in a sub-arctic bog peatland
(University of Waterloo, 2017-02-22)In Ontario’s James Bay Lowland, sub-arctic bog and fen peatlands make up 90% of the landscape. Increasing resource extraction operations in this area pose a risk of contaminant release into these systems, both intentional ... -
Understanding the Ecohydrological Role of Seasonal Ground Ice in a Boreal Peatland
(University of Waterloo, 2022-07-13)Seasonal Ground Ice (SGI) in peatlands forms in late fall when air temperatures begin to cool, and water in peat pores freeze. It differs from permafrost peatlands in that the SGI freezes and completely melts away every ...
