Staff 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).

When 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.

You 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.

In 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.

Under what conditions can trophic diversity relationships be eroded? Our Scale Invariance in Aquatic Ecosystems working group seeks to answer that very question as we study patterns in trophic diversity relationships within aquatic ecosystems where species turnover is often significant.

Our Structural Early Warning Signals in Aquatic Ecosystems working group is investigating how the basic connections between the organization and operation of ecosystems (such as the arrangement of different life stages and the structure of food webs) can be disrupted by global changes.

By 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.

Our planet faces a growing need for watershed restoration. Human activities like wastewater production, fossil fuel emissions, deforestation, and intensive agriculture have disrupted the delicate balance of nutrient flows between land and water.
