As northern lakes heat up, Canada’s lake trout are losing their individuality — and with it, a key source of ecological resilience. A new study in Ecology led by Cassandra Kotsopoulos at the University of Guelph examined lake trout across 52 boreal lakes in Ontario.
Read MoreA new study co-authored by the Centre for Ecosystem Management’s Dr. Kevin McCann reveals that agricultural land use—especially nutrient runoff and the loss of streamside vegetation—is reshaping how energy flows through stream food webs.
Read MoreWhen we talk about climate change, we often think in extremes—heat waves, vanishing glaciers, and species on the brink. But nature’s responses to these shifts are far more nuanced, and according to a new paper co-authored by the Centre for Ecosystem Management’s Dr. Joey Bernhardt, understanding when ecosystems respond may be just as important as understanding how they respond.
Read MoreYou don’t always need massive datasets to learn something important about nature. While modern ecology often focuses on large-scale “big data,” a recent study carried out, in part, by one of our collaborators Dr. Robert Hanner shows that smaller, less-than-perfect datasets can still reveal important patterns—if analyzed carefully.
Read MoreImagine walking through a forest, surrounded by towering trees, rustling leaves, and the distant hum of insects. Now, imagine trying to trace every single interaction happening in that ecosystem—from the tiniest ant nibbling on a leaf to a hawk soaring above, searching for its next meal.
Read MoreIn the dynamic landscape of ecology and evolution, embracing open science is no longer just an option—it's a necessity. As the movement towards transparency and data accessibility gains momentum, the skills associated with open science are becoming invaluable for budding ecologists and evolutionary biologists.
Read MoreIn a study led by Mx. Jade Dawson (and co-authored in part by our own Dr. Kevin McCann), we delve into the intricate world of freshwater food webs to uncover the resilience of Canadian fisheries in the face of environmental challenges.
Read MoreWe’re not the only ones excited about this recent study published in the Canadian Journal of Fisheries and Aquatic Sciences (carried out with the assistance of the CEM’s Director, Dr. Kevin McCann)….!
Read MoreExciting discoveries emerge from an investigation into the impact of climate change on five key freshwater fish species! A new study published in the Canadian Journal of Fisheries and Aquatic Sciences and carried out with the assistance of the CEM’s Director, Dr. Kevin McCann, looks at how freshwater fish body sizes respond to warming.
Read MoreBy measuring the variables of population growth rate and competitive ability (i.e. how well a species can use limited resources), the authors - including the CEM’s Dr. Joey Bernhardt - investigated the effects of climate warming on the competition amongst four species of phytoplankton under limiting nitrate.
Read MoreA study co-authored by the CEM’s Kevin McCann analyzed data from 133 economic crisis events in 98 countries over 40 years and found that countries that used a variety of electricity sources took longer to recover from crises.
