New research led by ecologists at the Centre for Ecosystem Management (University of Guelph) is arguing that ecosystems are far more fluid than we once believed. In a changing world, ecological networks are constantly “rewiring” themselves as species alter who they interact with, where they feed, and how strongly they depend on one another.
Read MoreA new study led by one of our postdoctoral fellows, Dr. Jason Laurich, looks at a framework that may help predict how species can—and cannot—adapt to increasingly complex conditions in a world facing rapid environmental change.
Read MoreHarmful algal blooms (HABs) are becoming an increasingly serious problem in lakes worldwide, driven largely by nutrient runoff from agriculture and urban development. A new study co-authored by our director, Dr. Kevin McCann, delves into how one particular neurotoxin and its related compounds move through the food web in Lake Erie.
Read MoreThe NSERC Food Web Alliance is a recently-funded project designed to tackle a major challenge in Canada and beyond: understanding and mitigating the combined impacts of multiple stressors—such as nutrient loading, harvesting, climate change, and invasive species—on the sustainability of Great Lakes fisheries and their food webs.
Read MoreA recent informal postdoc symposium brought together our ten researchers for a fast-paced, idea-rich day built around short, focused presentations that sparked questions and discussion.
Read MoreA new Ecology Letters article authored in part by our own Dr. Joey Bernhardt tackles a challenge that is becoming central to how we understand the effects of climate change on ecosystems: the disconnect between environmental conditions and the biological communities that live in them.
Read MoreWe are delighted to congratulate one of our postdoctoral fellows - theoretical/computational ecologist Dr. Kayla Hale - on securing a new position at the Santa Fe Institute.
Read MoreEvery week at the Centre for Ecosystem Management (CEM), our postdoctoral fellows (PDFs) gather for a standing meeting that’s part think tank, part sounding board, and part creative laboratory.
Read MoreWe are delighted to announce that our own Dr. Joey Bernhardt has been selected as this year’s recipient of the Stevenson Lectureship Award in recognition of her exceptional scientific leadership and achievement in the aquatic sciences.
Read MoreA day of outdoor exploration, wildlife sightings, and freshwater science came to life as some of our postdoctoral fellows led a hands-on outreach event for local youth on the Saugeen Peninsula.
Read MoreInvasive mussels are still making headlines, as their impacts continue to threaten Great Lakes whitefish on both sides of the U.S.–Canada border.
Read MoreEcosystems around the world are speeding up — but what does that mean for their stability and the resources we depend on? A new international working group led by Dr. Kayla Hale at CEM explores how the pace of primary producers sets the rhythm for entire food webs.
Read MoreThe 40th annual Neyaashiinigmiing Traditional Pow Wow brought together community and culture in early August in Cape Croker, attracting several hundred attendees from multiple states and provinces.
Read MoreAt the Centre for Ecosystem Management (CEM), we believe that science grows stronger when knowledge is shared. That’s why we advocate for open data practices across ecological research and environmental management.
Read MoreAs 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 MoreWe are excited to welcome Dr. Carling Bieg to the Centre for Ecosystem Management! Dr. Bieg is a theoretical ecologist who studies how ecological systems respond to global change across scales of space, time, and the ecological hierarchy.
Read MoreStaff from the Quantitative Fisheries Center and Centre for Ecosystem Management recently came together for their annual meeting set against the lush green backdrop of the Arboretum Centre (University of Guelph).
Read MoreWe’re excited to welcome our newest postdoctoral fellow, Dr. Megan Szojka, to the Centre for Ecosystem Management (CEM)!
Read MoreFreshwater ecosystems are under growing pressure from human activities like development, climate change, and pollution. But how do we know when fish are most at risk—and how can we use that knowledge to better protect them?
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.
