Aquatic macroinvertebrate communities and diversity patterns in the Northern Prairie Pothole Region
(University of Waterloo, 2017-04-26)The Northern Prairie Pothole Region (NPPR) of Alberta, Canada contains numerous shallow marshes that serve as important habitat for wildlife and provide many essential ecosystem services. Many of these pothole wetlands ... -
Avian species richness elevational patterns in mountain peatlands
(University of Waterloo, 2020-08-17)Avian research and elevation gradients have been studied extensively in the last century but there is a lack of understanding of the patterns and underlying mechanisms that drive avian species richness in mountain peatlands. ... -
Best Management Practices for Invasive Phragmites Control
(University of Waterloo, 2017-05-18)The invasion of European Phragmites australis in North America has altered resident species plant assemblages in wetlands and created large monotypic patches. As a response, North American land managers control this invasive ... -
Detecting the effects of biological invasion and subsequent control efforts on wetland ecological processes
(University of Waterloo, 2018-09-21)Meadow and emergent cattail wetland communities in eastern North America are being replaced by an invasive lineage of <i>Phragmites australis</i>. This invasion has consequences for wetland ecosystem functions; including ... -
The effect of glyphosate on bacteria and archaea community composition in freshwater biofilms
(University of Waterloo, 2022-04-04)Glyphosate-based herbicides are some of the most widely used herbicides in the world today, however, there is still much to learn about how glyphosate affects non-target ecosystems. Specifically, freshwater aquatic biofilms ... -
Eleocharis geniculata (Bent Spike-rush) Great Lakes Plains population: conservation in the face of invasion
(University of Waterloo, 2020-05-28)Eleocharis geniculata is listed as endangered under the Canadian Species at Risk Act, S.C. 2002 and the Ontario Endangered Species Act, S.O. 2007. Despite these listings, the current Ontario government recovery strategy ... -
Evaluating the development and use of a rapid wetland assessment tool (ABWRET-A) in policy implementation in Alberta, Canada
(University of Waterloo, 2020-06-03)As wetlands around the world are being lost, policies are implemented to help protect further destruction and loss of valuable services that wetlands provide. In Alberta, wetland policy has been put in place with the goals ... -
Land Use and Climate Influence Marshes in the Northern Prairie and Parkland Region
(University of Waterloo, 2016-01-21)I evaluated the association between waterbird communities and agricultural activity at 48 non-permanent wetlands, and waterbird response to inter-annual climate variation at 24 non-permanent wetlands. I found six distinct ... -
Local and landscape drivers of aquatic biodiversity in urban stormwater management facilities
(University of Waterloo, 2022-05-20)Stormwater management facilities (SWMFs) are often constructed in urban areas to provide flood mitigation and runoff control, and thus replace some wetland functions. Yet, their suitability as habitat for wetland biota is ... -
Long-term Effects of a Phragmites australis Invasion on Birds in a Lake Erie Coastal Marsh
(University of Waterloo, 2016-12-23)Invasive Phragmites australis threatens the integrity of essential bird habitat in coastal marshes. Located on the north shore of Lake Erie, Long Point, Ontario provides habitat to thousands of breeding and migrating birds, ... -
Monitoring Wetland Integrity and Restoration Success with Avifauna in the Prairie Pothole Region of Alberta, Canada
(University of Waterloo, 2017-01-19)In response to high wetland losses, and in recognition of the ecological functions and services provided by wetland ecosystems, updated wetland policy in Alberta focuses on protecting these important system and mitigating ... -
Movement of mature and early life stages of the Grand River walleye (Sander vitreus) population in Lake Erie's eastern basin
(University of Waterloo, 2020-09-04)Lake Erie’s commercial and recreational walleye fishery is the largest of the Great Lakes, requiring effective management to maintain a sustainable and complex fishery. Lake Erie’s walleye fishery is composed of multiple ... -
Multi-trophic effects of invasive species suppression in a coastal wetland
(University of Waterloo, 2021-05-25)Wetlands provide essential habitat for hundreds of species, including many that are of conservation concern in Canada. In southern Ontario, two wetland complexes, Long Point Peninsula and Rondeau Provincial Park, represent ... -
Native Wetland Plant Recovery Following Phragmites australis Invasion
(University of Waterloo, 2022-05-20)Invasive common reed (Phragmites australis ssp. australis) has negatively affected 25% of all Species at Risk in Ontario since its arrival in the twentieth century. This is of particular concern at Long Point and Rondeau, ... -
Physicochemical and Vegetative Responses of Prairie Wetlands to Local Land Covers
(University of Waterloo, 2016-09-28)Effective environmental monitoring and biological assessment initiatives require knowledge of the spatial and temporal scales at which human activities most strongly influence ecosystem conditions. I compared the environmental ... -
The Role of Wetland Pond Permanence in the Assembly of Biological Communities in the Prairie Potholes of Alberta
(University of Waterloo, 2020-05-06)Wetlands in the Prairie Pothole Region (PPR) support numerous biological communities, and the composition of these communities depends on the length of time ponded water is present (i.e., hydroperiod or permanence class). ... -
Use of Water Isotope Tracers to Characterize the Hydrology of Prairie Wetlands in Alberta
(University of Waterloo, 2018-01-22)Our understanding of prairie wetland hydrology comes primarily from a handful of long-term research stations, but generalizing from a few intensively monitored areas to the entire prairie pothole region requires assumptions ... -
Vegetation Based Assessment of Wetland Condition in the Prairie Pothole Region
(University of Waterloo, 2018-01-22)The northern prairie pothole region (NPPR) in central and southern Alberta contains numerous shallow, open-water pothole wetlands that provide important ecosystem services to the region, such as flood mitigation. To address ... -
