Dark Skies with Kayla Browne and Dan Duriscoe

In 1999, the once-healthy population of Catalina foxes plummeted suddenly and without explanation. Over the next few years, scientists worked to find out what was wrong and to bring this tiny fox, found nowhere else on earth, back from the brink. Join me and Lauren Dennhardt as we discuss Catalina fox's story, and then come with me into the field with Katie Elder to trap foxes for their annual population count and vaccinations.

Humans have been fascinated by islands since the writing of the earliest works of literature, but the outsized role they play in our imaginations isn't limited to fiction. Islands make up only a tiny percentage of the land on earth, but they represent about a fifth of the planet's total biodiversity. And things stranger than fiction happen on islands, from the evolution of miniature mammoths and enormous flightless birds with no fear of humans to the illumination of the theory of evolution itself. Join me and two experts, Kevin Alison and John Knapp, as we trundle along island roads deep into the unique ecology of Santa Catalina Island and discuss giant buckwheats, tiny foxes, and what islands have to teach us about the living world back on the mainland.

The pod is going stronger than ever, but it's also part of a larger picture than ever, which means a little shuffle is in order. Have a listen to find out the specifics. I'll see you on the next full episode soon!

The golden hills of California are hiding things. At first glance, grasslands like these ones appear to be simple systems. And to some degree, they are simplified versions of their precolonial selves, but they’re also home to thousands of species of native plants that support an intricate ecology. Look a little closer, peer between the swishing blades, know what to look for, and you’ll see not only a mesmerizing web of life but also California’s history written in the grass. Come with me and Dr. Justin Luong of UC Berkeley as we explore a California grassland and discuss the past, present, and future of an ecosystem vital to both biodiversity and human wellbeing.

Seeds are far more present in our lives than most of us realize. They compose everything from our morning coffee to our favorite chocolates and have helped shape the world as we know it. California native seeds are just as vital, and protecting them is a way of safeguarding our very future. Join me and Cheryl Birker at the California Botanic Garden as we explore the hidden world of seeds. In this episode, we take a deeper look into the difference between spores and seeds, seeds that require fire to germinate, seeds that survived for 2,000 years in the Judean Desert, and how safeguarding seeds is a way of safeguarding life as we know it.
