Congratulations to Dr. Timothy Fernandes on his new position as Northern Fisheries Research Scientist with the Ontario Ministry of Natural Resources Cooperative Freshwater Ecology Unit in Sudbury, Ontario!

Dr. Kevin S. McCann has been invited to a special Santa Fe Institute Colloquium Series in October 2027 in Santa Fe, New Mexico, where he will provide a talk entitled, "On the Noisy Balance of Nature in a Changing World." Read the below excerpt from Dr. McCann where he summarizes key arguments he will be covering in his upcoming presentation. In this talk I examine the dynamics and stability (broadly defined) of ecological systems from both a theoretical and empirical perspec

After completing his PhD in January of 2026, Dr. Reilly O'Connor has accepted a new position as a Post-Doctoral Researcher at the German Centre for Integrative Biodiversity Research (iDiv) - Halle - Jenna - Leipzig with Dr. Susanne Fritz & Dr. Ulrich Brose. Here he will be investigating the relationships between biodiversity, species traits, food web structure and island biogeography.

In a May 2026 CBC News feature, food web ecologist Dr. Kevin McCann breaks down how released pet goldfish act as a highly reproductive, competitive invasive species that undergoes runaway population growth. This surge degrades local freshwater ecosystems by driving up water turbidity, outcompeting native biodiversity, and threatening local fish stocks with foreign pathogens. The McCann Lab's contribution to the article underscores the vital importance of public ecological awa

Led by Dr. Kayla R. S. Hale and co-authored by Dr. Kevin McCann alongside an interdisciplinary team, this paper tackles how human-driven global change is eroding the natural stabilizing structures of the Laurentian Great Lakes Basin. The authors highlight "portfolio effects"—where diverse biological components and variable habitats fluctuate asynchronously to stabilize the aggregate ecosystem—as a critical target for conservation. By tracking how mobile consumers adaptively s

In a recent Nature Ecology & Evolution (2026) article, the McCann Lab at the University of Guelph, introduces "trophic hotspots" as a dynamic framework for understanding ecosystem function, driven by spatiotemporal heterogeneity and consumer movements. This study argues that these localized, energetic hubs are crucial for managing ecosystem resilience against perturbations. Read more about this work, including key concepts like biodiversity hotspots and foraging theory, in th
