The Puma Guy, Chris Wilmers, on the Science of Coexisting with Local Mountain Lions

Mountain lions are slipping through our neighborhoods under the cover of darkness, radically altering their behavior just to avoid us. In this episode, Chris Wilmers, UC Santa Cruz professor of wildlife ecology, pulls back the curtain on the cryptic world of our region's apex predators. From a toothless "old man" puma targeting local livestock to the hidden ways backyard rat poison disrupts local food webs, Wilmers breaks down the true cost of human coexistence. As concrete barriers slice ancient habitats into fragments, local conservationists are fighting back with innovative wildlife crossings. Can these modern solutions truly mend a fractured landscape, or will a dominant male's desperate attempt to cross Highway 17 end in disaster?

Mayor Fred Keeley on How Santa Cruz Reshaped California’s Ocean Protection Laws

How does science actually become law? In this episode current Santa Cruz Mayor, Fred Keeley, reflects on his legendary career rewriting California’s ocean protection rules. From body surfing through literal oil slicks as a nine-year-old to passing the historic Marine Life Management Act at the final midnight hour of a governor's term, Keeley shares what it really takes to build a "Blue Wall" for the coast. But with old political battles over offshore drilling and seabed mining rearing their heads once again right here in the Monterey Bay, the stakes have never been higher. As one of our region’s most iconic policymakers prepares for retirement, he passes the baton to a new wave of local coastal leaders who must now defend these waters.

FIELD DIARY: Patrolling Peregrines on Site with Zeka Glucs

The California coast is witnessing a silent crash in peregrine falcons that threatens to outpace the devastating legacy of DDT. In this guest-hosted episode, Zeka Glucs, Director of the UC Santa Cruz Predatory Bird Research Group leads us into the field to track the invisible killer: bird flu. From the studio to the windswept bluffs of Devil's Slide, we witness the frontlines of an ecological battle against a virus these apex predators simply can't outfly. As Zeka's team monitors this unfolding crisis, we’re forced to confront the fragility of a recovery we once thought was permanent. We’re left to wonder: can these icons survive a second near-extinction, or are we witnessing the final flight of the peregrine on the Santa Cruz coast?

The April 2nd Wake-Up Shake: Santa Cruz’s Seismic Secrets with Emily Brodsky

The morning of April 2nd gave Santa Cruz a sharp reminder that the ground beneath our feet is never truly still. In this episode, we use that recent shake to uncover the seismic secrets lurking under our feet with Emily Brodsky, an earthquake scientist and UC Santa Cruz professor. From the legacy of the 1906 disaster to modern earthquakes triggered by geothermal energy and fracking, we explore the chain reactions that link tremors across the globe. As human activity shifts the stress on these deep-seated faults, we investigate if we are unknowingly triggering a cycle we can't stop. Is it possible to predict the next big shake, or will the next shift in the California coast, like the one on April 2nd, catch us all by surprise?
