Sustainable development of the Canadian economy requires wise stewardship of our environment and natural resources; this is particularly true given the anticipated impacts of climate change. Biomonitoring seeks to describe and understand biological diversity at multiple ecological levels, both as a means to learn the typical mix of species that can be found in different habitats, and to establish “biological early-warning systems” that can tell us when environmental stresses are reaching a critical point. Canada is recognised as a world leader in biomonitoring, however, current practices have limitations. They are personnel-intensive, which limit the frequency and intensity of sampling, particularly in remote areas. Also, present biomonitoring methodologies focus on a very limited subset of all species that can be found at a given location.

Our project introduces ‘Biomonitoring 2.0′, a system based on cutting-edge DNA-sequencing technologies and state-of-the-art computational analysis, which will simultaneously reduce sample costs while dramatically increasing the knowledge gained from biological samples. The first test bed for this new system is Wood Buffalo National Park, a globally unique region spanning Alberta and the North West Territories that is under considerable threat from oil sands activities and other human impacts, in spite of its remoteness and protected status. Following testing, the protocol will be applied at other global locations. By integrating our new genomics tools and technologies into a well-established Canadian biomonitoring framework, the Canadian Aquatic Biomonitoring Network (CABIN), we will greatly increase our potential to manage our cherished national resources. The project team has been working closely with stakeholders including industry, government departments, First Nations and Metis, and environmental organizations. By developing a sophisticated, yet user-friendly Web-based portal, with client-based customized tools, we will be able to communicate much richer summaries of environmental health and impacts to society, through direct interactions with local stakeholders.

The Biomonitoring 2.0 project is divided into four, separate, but interdependent, spheres:





Sustainable development of the Canadian economy requires wise, responsible stewardship of our environment and natural resources: this is particularly true given the anticipated impacts of human activities from urbanization to agriculture to the mining and energy sectors. Biomonitoring provides an “early warning system” for environmental degradation by using the differential sensitivity of certain groups of organisms (a.k.a. bioindicators) to environmental stressors. Canada is recognised as a world leader in biomonitoring, however, conventional biomonitoring approaches are personnel-intensive as they involve sampling organisms and identifying them from their physical appearance. Given the difficulties in accurate identification of bioindicator organisms, such as the larvae of aquatic insects, biomonitoring is performed with a limited frequency and intensity and has become a major bottleneck in environmental assessment programs. Working in close collaboration with Environment Canada, we have developed Biomonitoring 2.0, which uses DNA sequence information for identifying all organisms in an environment. Our approach can circumvent the identification bottleneck through bulk sampling and directly identifying organisms from mixtures. We obtain species-specific DNA fragments (DNA barcodes) from any environmental sample (soil, water, sediment, air) using cutting-edge, high-throughput next generation sequencing technologies rapidly and cost-effectively. By targeting multiple habitats in an environmental setting, we can provide a comprehensive (all taxonomic groups from mammals to microbes) and high-resolution (species-level) view of environmental change (Figure 1). Hence, the Biomonitoring 2.0 approach can simultaneously lower biological sampling costs while dramatically increasing the knowledge gained from those samples.


Biomonitoring 2.0 in Practice

We have successfully tested Biomonitoring 2.0 in a number of proof-of-concept studies (References 1-3). Since 2011, we have been conducting the first large-scale pilot project for this approach at Wood Buffalo National Park (WBNP), a globally unique region spanning Alberta and the Northwest Territories that is under considerable influence from oil sands activities. This project gained first ranking in a national Genome Canada Large Scale Applied Genomics competition and involves seven research groups at five universities as well as researchers and officers of Environment Canada and Parks Canada. Our project has now been included in the recently announced Integrated Monitoring Plan for the Oil Sands. Hence, our sampling will dramatically increase beyond WBNP boundaries and into the oil sands region of Alberta. The information gained in this project will significantly aid the implementation of an objective, comprehensive, scientifically credible environmental assessment program for the oil sands industry.


Fig 1: High-throughput, next generation sequencing ecological heat maps were generated to differentiate biodiversity in specimens obtained from two sampling sites (blue and green bars) in Wood Buffalo National Park. The six different genetic markers were chosen so as to capture the greatest diversity of taxonomic groups from the various samples. Environmental samples typically include soil, water, benthos and terrestrial arthropods.

The Future of Biomonitoring 2.0

In addition to continuing our biomonitoring program in WBNP and the oil sands, we are embarking on a number of international collaborations to promote the dissemination and adoption of the methodologies that we have pioneered, and to link ongoing projects currently underway in Canada, the USA, the UK, France and Australia. Our expanding network includes academia, industry, government and NGOs. In this way, Biomonitoring 2.0 is poised to play a significant role in informing crucial decisions on management and conservation in Canada and the world.
