Are Grizzly Bears Apex Predators & Keystone Species? || Project Grizzly Balance || Ep. 9

What if the real keystone players are invisible, microscopic, and often overlooked? In this eye-opening episode, Mark deconstructs the narrative of large predators as the primary regulators of ecosystems. Using an ecological perspective, Mark reveals the species that hold the true power over habitat health, biodiversity, and resilience. You’ll discover that ecosystems are complex networks, not simple pyramid hierarchies, and that prioritizing charismatic megafauna might obscure the real drivers of ecological stability. In this episode Mark breaks down: the origins of the apex predator and keystone species concepts, why Yellowstone’s ecosystem hasn’t been the dramatic wilderness transformation it’s often made out to be and how scientific narratives are skewed by a mammal-centric bias.
