Disentangling Effects of Multiple Stressors on Nuisance Benthic Algae (Cladophora) in Nearshore Regions of the Great Lakes

We will analyze long-term monitoring data that were sampled over ten years from nearshore regions of the Great Lakes to find out key factors that cause the proliferation of nuisance benthic algae and fouling of shorelines of Lake Ontario in the Toronto–Durham region and throughout the Great Lakes. Additionally, we will test whether environmental DNA in water and sediment samples can be used to track the dispersal of nuisance benthic algae. Our project will contribute directly to the ongoing monitoring programs in the Great Lakes and will be relevant for management of nuisance benthic algae.

Sustainability Analysis of the VOCs Abatement Solution Proposed by SunHub Inc. for Small and Medium Enterprises in the Furniture Industry in China

Volatile Organic Compounds (VOCs) are major contributors to smog, causing harm to both the environment and human health. However, VOCs control faces tremendous challenges. The aggregation of low VOCs concentration emitted by small and medium-sized enterprises (SMEs) have significant environmental and social impacts. However, SMEs find the current “on the market” technologies impractical and too expensive in initial investments and operational maintenance costs. To help alleviate the problem, SunHub Inc.

Development of a novel IPM strategy for brown marmorated stink bugs (Halyomorpha halys) using RNA interference (RNAi) technology - Year two

Brown marmorated stink bug (BMSB) (Halyomorpha halys (Stål)) is an invasive pest with a large host range that includes many economically important fruits, vegetables, and row crops. Native to Asia, BMSB was first detected in North America in 1998 and since has become established in British Columbia, Quebec, and Ontario; and 44 American states. In order to develop efficient BMSB focused integrated pest management program (IPM), it is critical that novel alternative control tactics are investigated primarily because there are no effective insecticides available.

Effectiveness of vegetation and habitat characteristics as predictors of insect parasitoid populations - Year two

Climate change, land development, invasive species, and other disturbances can alter the composition, structure, and functions of native vegetation across landscapes. These disturbances also impact insect parasitoids, which are a key, and often overlooked, component of biodiversity. By their ability to control other insect populations, they are integral for fostering resilient and functional forests.

Geosynthetic drainage for improved stability of fine-grained materials in slopes & embankments

Innovative geosynthetic drainage products have been developed that have the potential to significantly benefit the stability of constructed embankments or reconstructed slopes especially where these are constructed from soil (or soil-like materials such as tailings) that are finer and less permeable (and thus weaker) then free-draining coarse-grained granular fills. Applications include reconstruction and stabilisation of natural slopes, embankments or dams constructed of (or at least partly from) mine tailings or other finer-grained materials.

Investigation of the relationship between firefighting water additive formulation and environmental fate and toxicity

Firefighting water additives are a mixture of chemicals that are mixed with water to more effectively extinguish fires (i.e., residential, industrial, forest fires). The use of these additives is likely to increase in fighting forest fires due to the projected increase in forest fire occurrence and intensity due to climate change. Ingredients of firefighting water additives used in the past were found to be persistent and detrimental to the environment.

Municipal Energy Futures Project: A Case Study of Regina, Saskatchewan

Meeting Canada’s commitment to the Paris Agreement will require a fundamental shift in the energy systems of
Canadian cities. Regina, Saskatchewan is located in the sun-belt of Canada and also lies within the Great Plains wind corridor. Recognizing this potential for renewable energy, the City of Regina has committed to a target of meeting 100% of its energy needs using renewable energy by 2050.

Root associated microbiome of trees growing in a fractured bedrock toluene phytoremediation site

Phytoremediation is a promising in-situ technology that uses plants and its associated microorganisms (particularly bacteria and fungi) to clean up contaminated soils. The efficacy of these processes however, requires an in-depth knowledge on the diversity of microbial communities closely interacting with plant roots. Several studies have demonstrated that plants growing in contaminated soils select for competent microorganisms able to degrade these contaminants.

Do existing lending products of credit unions meet the financing needs of co-operatives - The case of Libro Credit Union and Ontario’s Co-operative Sector

Credit unions and co-operatives share a common identity and foundational values as organizations that meet the economic, social, and cultural needs of their member-owners. A perennial concern for the credit union and co-operative sectors has been the need to identify opportunities for collaboration to advance the prominence of member-owned models. This research surveys and interviews co-operatives in Southwestern Ontario to understand their financing needs, and to identify why existing financial products do not meet these needs.

Long-term effects of tillage, crop rotation, cover crop, and fertilizer nitrogen on soil organic carbon and total nitrogen storage

Soil organic matter and soil organic carbon (SOC) are the important drivers of soil health. Although winter wheat and red clover have improved the soil health and system resiliency in Ontario (Gaudin et al., 2013), little is known on how quickly changes to soil health can be made and under which management systems. With Federal and Provincial government policies on carbon trading, a better understanding of the impact of management on carbon sequestration would be valuable. However, meaningful Ontario data are needed.
