The fate of North America's most valuable freshwater system rests in the hands of dedicated scientists working across political boundaries. Greg McClinchey from the Great Lakes Fishery Commission returns to Under the Canopy to reveal the fascinating story of how this binational organization has battled invasive sea lamprey for nearly 70 years while coordinating fisheries management across multiple jurisdictions.
Greg reveals the remarkable impact these parasitic invaders have had on Great Lakes ecosystems. Each sea lamprey consumes approximately 40 pounds of fish during its lifetime, while females produce around 100,000 eggs. Left unchecked for just 3-5 years, these invaders would collapse fish stocks throughout the basin. Through dedicated control efforts using targeted lampricides in tributary streams, the Commission has reduced lamprey populations by about 90% from their peak.
The conversation takes unexpected turns, including the surprising story of how lamprey from the Great Lakes became part of a royal pie for Queen Elizabeth II's Golden Jubilee when lamprey couldn't be harvested from their native English waters due to conservation concerns. While European lamprey are considered delicacies, Greg explains why Great Lakes lamprey are unsafe for human consumption due to accumulated heavy metals.
We explore cutting-edge science initiatives like the Great Lakes Acoustic Telemetry Observation System (GLATOS), which tracks fish movements throughout the lakes, and the potential for mass-marking hatchery fish. Most impressively, Greg shares news that lake trout populations in Lake Superior have been fully restored – a landmark conservation achievement after decades of work.
What stands out most is how this international organization maintains unanimous, science-based decision-making even during periods of political tension between the U.S. and Canada. The Great Lakes Fishery Commission stands as a model for how shared commitment to natural resources can transcend politics to achieve remarkable conservation outcomes. -
Professor James A. Scott takes us on a mind-expanding journey through the invisible world of microorganisms that profoundly shape our health from birth through adulthood. As an expert from the University of Toronto's Dalla Lana School of Public Health specializing in biological hazards, Scott reveals how the first 100 days of a baby's life represent a critical window when their gut microbiome—the complex community of bacteria living in our digestive systems—establishes itself and essentially "trains" their immune system.
The conversation challenges much of what we thought we knew about cleanliness and health. Scott explains how our modern obsession with sterilizing environments may actually contribute to rising rates of allergies and asthma. Surprisingly, exposures to certain microbes early in life appear protective rather than harmful.
This fascinating episode also delves into Scott's work preserving one of the world's most important fungal biobanks—a collection of approximately 15,000 living fungal strains, some dating back to the 1880s, including historically significant specimens like Alexander Fleming's original penicillin-producing mold. Despite its irreplaceable scientific value, this biological treasure trove faces an uncertain future due to funding challenges, highlighting the precarious nature of preserving biodiversity for future medical discoveries.
Whether you're a parent curious about giving your child the healthiest start in life, someone struggling with allergies or immune issues, or simply fascinated by how our microscopic companions influence our wellbeing, this episode will transform how you think about the relationship between humans and microorganisms.

The forest canopy above us holds secrets most people never notice—miniature ecosystems thriving on tree trunks that tell profound stories about our changing world. In this eye-opening conversation with Dr. Yolanda Wiersma, professor of biology at Memorial University in Newfoundland, we venture into the fascinating realm of landscape ecology and lichen biodiversity.
Dr. Wiersma introduces us to landscape ecology—a discipline studying interactions between living things and their environments at scales visible from airplane windows. From the rolling hills and forests to human developments cutting across them, these patterns shape everything living beneath the canopy. Her work bridges traditional scientific approaches with Indigenous knowledge, leading to remarkable discoveries in unexpected places.
The heart of our discussion revolves around lichens—organisms far more complex than most realize. These aren't single lifeforms but miniaturized ecosystems combining fungi, algae, and sometimes bacteria from three different kingdoms. Dr. Wiersma's passion shines as she describes how these slow-growing organisms "eat the air" through photosynthesis while producing hundreds of unique chemical compounds, some with antimicrobial properties so effective that birds line their nests with them to protect vulnerable chicks.
Perhaps most surprising is Dr. Wiersma's discovery of a lichen biodiversity hotspot in central Newfoundland—an area previously overlooked by scientists until a member of the Qalipu First Nation reached out with photographs of rare specimens. This collaboration led to documenting 175 species in a region not previously known for lichen diversity, highlighting how traditional knowledge enriches scientific understanding.
Whether you're a nature enthusiast, someone curious about the hidden workings of our forest ecosystems, or simply appreciate learning about overlooked wonders in our natural world, this conversation will transform how you see the trees around you. Listen now to discover the miniature worlds thriving silently above our heads and what they can teach us about our changing planet. -
Dr. Matthias Bierenstiel shares how ancient Mi'kmaq knowledge about birch bark medicine combined with modern chemistry is transforming skin care and challenging Western approaches to medicine.
• Dr. Bierenstiel, a chemistry professor at Cape Breton University, partnered with Mi'kmaq Studies professor Tuma Young to research traditional birch bark extract
• The collaboration uses "two-eyed seeing" methodology, combining indigenous knowledge with scientific analysis
• The knowledge was nearly lost - rescued from just two Mi'kmaq elders who remembered a story about a nursing mother healed in the 1920s
• Chemical analysis reveals over 200 compounds working together as a "symphony" rather than single active ingredients
• The extract shows remarkable effectiveness for skin conditions like eczema, psoriasis, and even poison ivy
• Traditional extraction methods involving fire were critical - lab replications initially failed until they mimicked the earth's thermal protection
• Only outer layers of paper birch bark are harvested sustainably without harming trees
• The research led to founding Masqueomi, a small company selling creams and soaps with the community's blessing
• Current products are sold under cosmetic licensing while research continues toward natural health product certification

Jerry Ouellette, former Ontario Minister of Natural Resources, and Mike Holland, who held the same position in New Brunswick, reveal how they navigated government systems to achieve meaningful conservation victories.
Jerry's innovative classroom hatchery program stands as a testament to creative problem-solving—targeting schools along waterways to transform potential polluters into stream stewards. By involving students in raising and releasing rainbow trout, he created both environmental improvements and a generation of conservation-minded citizens. Today, tens of thousands of rainbow trout return to these streams annually, a testament to how small, strategic interventions can yield remarkable results.
Mike Holland approached his ministerial role with similar pragmatism. After founding the Canadian Wild Turkey Federation, he leveraged his position to establish New Brunswick's first-ever turkey hunt—defying bureaucrats who had repeatedly deemed it impossible. His department became the only financially self-sustaining branch of government by recognizing conservation's economic potential alongside its biological importance.
The conversation shifts to the Canadian Wild Turkey Federation's remarkable journey from "two guys in a half-ton truck" to a national organization with chapters across the country. What makes this story particularly fascinating is how chapters thrive even in provinces without turkey hunting seasons, demonstrating a commitment to conservation that transcends specific species or activities. Their youth "hoot and shoot" programs teach comprehensive outdoor education, producing conservationists who now work professionally in natural resources.
Whether through classroom hatcheries, turkey habitat restoration, or youth mentorship, both leaders demonstrate that effective conservation requires connecting people with nature in meaningful ways. Their shared experiences offer a masterclass in turning passion into policy and obstacles into opportunities.
