Research focus and activities

Our research group investigates water quality in runoff from agricultural fields and watersheds. We emphasize phosphorus losses in tile drainage and overland flow, year round. We are particularly interested in winter and snowmelt. We also investigate if and how best management practices (BMP) can be used to improve water quality and reduce nutrient losses in runoff.

We process and analyze soil, plant and water samples. We analyze for nutrients (nitrogen, phosphorus) and also major ions. Sometimes we do experiments in the lab using soil and plant collected from the field.

We are making a lot of progress on understanding the role of tile drainage in phosphorus losses from farm fields, and also understanding how important the non-growing season (October – April) is for annual phosphorus losses.

Fun facts

As a lab, we drink over 37 litres of coffee in a work week (I did the math, there are 10 of us), enough caffeine to stay productive.

The only clock in the lab doesn't work, instead we have sharpied: "it's always time for science" on it.

Research focus and activities

We focus is on conservation ecology, especially in parks and protected areas. We take an inclusive approach as projects include population and community ecology studies on different habitats (e.g., prairies, forests, wetlands, shorelines, rivers) and taxa (e.g., plants, fungi, herptiles, arthropods, annelids). We work on the larger socioecological issues involved in management and governance needed to provide a desirable and resilient ecosystem – we have worked with municipalities, NGOs, private sector partners, federal and provincial agencies, and world organizations such as the United Nations (UN).

Restoration ecology/resilient ecosystems frame our other major focus. Stephen Murphy has chaired the Society for Ecological Restoration of Ontario, organized several of the International Meetings of the Society for Ecological Restoration, and is Editor-in-Chief of the journal Restoration Ecology. Steve and his team have led or participated in over 1,500 restoration projects. We’ve restored functional aspects of novel and more historical ecosystems and restored prairies, forests, wetlands, shorelines, rivers, and meadows in rural and urban areas.

Research focus and activities

The Cryospheric Remote Sensing Research Facility (CRSRF) was established in 2009 by Professors Claude Duguay and Richard Kelly with funding obtained from the Canadian Foundation for Innovation and the Ontario Ministry of Research and Innovation.

Polarimetric ground-based scatterometer systems operating at Ku and X-band frequencies have been acquired to deepen our understanding of active microwave interactions with snow and ice properties. Our group is using the scatterometer systems and complementary field instruments to develop a rich understanding of radiative transfer and backscattering processes from snow and ice, and in the principles of snow and ice energy and mass balance processes. Graduate students are also being trained in the operation of automated weather stations with a suite of radiation and energy balance instruments, automatic ice profiler and snow depth systems as well as more traditional snow and ice field instruments such as snow tubes, ice corers and augers, density profilers and other standard snow survey techniques.

CRSRF provides the only Ku-/X-band scatterometer facility of its kind in North America.The infrastructure has previously been used in support of the CoReH2O satellite mission proposed to the European Space Agency.To date, the full suite of instruments has been deployed at several locations and sites (land, lake ice, sea ice) in Canada: Churchill, Manitoba; Resolute, Nunavut; and the Waterloo region.

Interesting fact

UW-Scat is well-travelled.  It has been deployed in arctic and subarctic environments such as Resolute, Nunavut and Churchill, Manitoba.  Within Ontario, it has been deployed in Maryhill, Tobermory, and Englehart.  It is scheduled for deployment near Grand Mesa, Colorado and Inuvik, Northwest Territories in early 2017.

Research focus and activities

Much of the research done in the lab is currently focusing on understanding the integrated ecohydrological behaviour of wetland and forest ecosystems, especially in the Western Boreal, Subarctic and Alpine regions, in the context of climate and landuse change.

Significant progress has been made in improving our understanding of the cumulative effects of landuse change and climate variability on hydrologic linkages in forest-wetland-pond systems in the plains region of the Western Boreal Forest. In particular: establishing the relative contributions of vegetation communities and landscape units to catchment scale evapotranspiration and greenhouse gas exchange; quantifying the effects of disturbance on evapotranspiration and greenhouse gas exchange, soil moisture distribution and lateral water movement between landscape units; and determining linkages/feedbacks between surface hydrological processes and carbon storage.

Over the past 5 years, significant research has been done applying what we have learned in these areas to large large-scale reclamation efforts, especially pertaining to oils sands development and mining, and conventional oil and gas exploration. Much of this research has contributed not only to the design of constructed systems (especially wetlands) but also to learning how best to evaluate the efficacy of reclamation strategies and success of landscapes post construction.

Recently, with collaborators at Western University, McGill University, Laurentian University and the Ontario Ministry of Natural Resources, the lab was awarded an NSERC Strategic Grant for an innovative program on peatlands and climate change.

Research focus and activities

Signature research areas include sustainable agriculture and agroforestry, soil health, biochar, greenhouse gas emissions, soil carbon sequestration, climate change impact on plants and soil, restoration/rehabilitation.

The goal at Soil Ecosystem Dynamics Lab (SED) is to enhance our knowledge on the transformations and processes that take place in the soil, and to examine the relationship between plants, soil and the atmosphere. By doing so, we hope to further understand how to use natural and managed ecosystems help mitigate climate change through carbon sequestration, by minimizing greenhouse gas emissions, and ensuring the long-term security of food and soil.

A new research interest in SED is a focus on biochar and its use as an agricultural soil amendment. We have launched the largest replicated biochar field trials in Ontario in 2016.

The SED research group frequently collaborates with international, national and local scholars that come to use our lab facilities. Infrastructure in the SED laboratory also supports other researchers within the Faculty of Environment. For further information on individual research projects, graduate students, publications and graduate student opportunities see the SED Lab website.

Mike Stone

Research focus and activities

Professor Stone’s research program is directed towards the study of land use change and its impact on surface water quality in natural and built environments. A particular focus of his research is to quantify and model the source, transport and fate of sediment associated contaminants in aquatic environments. He has conducted research in regions such as the Great Lakes Basin, Alberta, the Northwest Territories and China. Over the past 10 years his research has specifically examined the effects of wildfire on the mobility and downstream propagation of sediment-associated contaminants.

The Sediment and Water Quality lab has the capacity to analyze a range of nutrients and contaminants typically in the aqueous and solid phase. An Empix Image Analysis System is used to characterize the particle size distribution and fractal properties of cohesive sediment.

Professor Stone is the Downstream Propagation Node Leader of the award winning Southern Rockies Watershed Project.

Research focus and activities

Research in the Wildlife and Molecular Ecology Lab examines the factors that influence the fitness of animal populations at multiple scales – from genes to landscapes. The impetus for most of our research emerges from important conservation issues; however, we also endeavour to answer general ecological questions to improve concepts and theory in ecology and evolution. We focus on wildlife questions examining habitat selection, landscape genetics, population trends and social behaviour.

We integrate across disciplines in Ecology which often requires the use multiple tools to investigate priority research questions. In addition to our lab-based genetics research, we use the tried and true techniques of field-based research in wildlife capture, marking, and tracking. We also use multiple modelling approaches to understand the data we have collected and generated including Bayesian statistics, mixed-models, circuit theory, and machine-learning approaches. Much of the research in the lab focuses on a diverse array of avian species including grouse, waterfowl, raptors, and passerines. However, we do not limit our research to only birds and have also conducted research on herptiles, fish, insects, and mammals. Finally, we work closely with our management partners to ensure the relevance of our research to conservation and management actions.

Interesting fact

Our funding and research partners include the U.S. Bureau of Land Management, U.S. Fish and Wildlife Service, U.S. Department of Agriculture, Wyoming Game and Fish Department, The National Audubon Society, The Nature Conservancy, Ducks Unlimited Canada, Wildlife Habitat Canada, Ontario Ministry of Natural Resources and Forestry, and Parks Canada.

Chris Fletcher
Department of Geography and Environmental Management

Research focus and activities

Our research group conducts experiments on the global climate system, to discover what future climate change might look like in Canada and the Arctic. We run our experiments using computer models, which are numerical laboratories that provide a safe and controlled means of investigating how the climate system responds to increasing greenhouse gases, all from the comfort of our desks.  We are one of only a handful of University-based research teams using global climate models, and our team of postdocs, graduate and undergraduate students gain hands-on experience with using and perturbing these models.  The main modelling system we use is the Community Earth System Model built by the National Center for Atmospheric Research in Boulder, Colorado, but we also have expertise with a global land surface model developed by Environment and Climate Change Canada called the Canadian Land Surface Scheme (CLASS).

The group is engaged in diverse projects investigating global climate variability in change, with a focus on improving our fundamental understanding of dynamics and processes.  Through funding from the CanSISE network, supported by the NSERC Climate Change and Atmospheric Research program, we have recently provided new insight into the important role played by surface snow cover in climate change, particularly over forested regions of the northern hemisphere, such as those in northern Canada.  Supported by Prof Fletcher's NSERC Discovery Grant, we also focus on the dynamics of atmospheric teleconnections, climate phenomena that link variations in North American weather and climate to far-away regions of the Earth in the tropical oceans.  A third strand of our research involves translating future projections from global climate models to specific geographic regions (such as recent work producing future climate projections for Waterloo Region), or to specific socio-economic applications (such as our recent work quantifying the potential impact of climate change on highway pavement maintenance costs).

Interesting facts

Climate models are incredibly complex pieces of computer software, typically totalling more than one million lines of code, and occupying some of the fastest supercomputers in the world. Our group runs its simulations on the Compute Canada SciNet systems, located in west Toronto.  Climate models evolved from numerical weather forecasting models, and the first simulations of global climate change were completed in the late 1960s.  Amazingly, these first simulations projected about the same amount of future climate change as our most sophisticated models do today, demonstrating the science of climate change has been known and understood for a very long time.
