50 years of data reveals true extent of climate change impacts on kelp forests

Originally published on UVic News

New research from the University of Victoria (UVic) has found that some kelp forests around Vancouver Island were disappearing far earlier than scientists previously thought, highlighting that climate change has been altering our ecosystems long before most people were aware anything was wrong.

“Most research has focused on recent kelp forest losses resulting from well-known marine heatwaves, like the record-breaking ‘Blob’ heatwave that hit our coast a decade ago,” says Brian Timmer, a UVic PhD student, National Geographic Explorer and lead author of the study, recently published in Ecological Applications.

“These recent changes to our kelp forests have been intense. But our research shows that some areas of the BC coast have been warming much faster than the global average, and associated kelp declines began decades ago. We’ve been underestimating the magnitude of ocean-warming impacts for years.” Chris Neufeld, co-author and senior aquatic ecology at LGL Limited

Soil – The Quadra Project

When algae first emerged from the oceans some 480 million years ago to become plants, they had no roots, so they established a symbiotic relationship with fungi, which were essentially nothing but roots. The fungi had the capability of extracting critical moisture and minerals from the ground, while the algae could photosynthesize sugars from sunlight, so the two organisms established a mutually beneficial partnership. This is a subject that has been explored by Dr. Suzanne Simard in her seminal book, Finding the Mother Tree: Discovering the Wisdom of the Forest. Rupert Sheldrake has explored the mysterious world of fungi even further in his remarkable book, Entangled Life: How Fungi Make Our Worlds. And George Monbiot has added further dimensions to this fascinating subject in Regenesis, in which he examines the complexity of life systems in soils. Chapter 1, “What Lies Beneath”, is particularly illuminating.
