Seastar Wasting Disease

KZYX The Ecology Hour ·

2025/08/13

Eleven years ago, a mysterious disease killed most of the adult starfish off California and Oregon. The most severely affected, Sunflower Seastar, was the main predator limiting the spread of Purple Urchins. The sudden disappearance of a key predator triggered a "trophic cascade" that led to an ongoing ecological crisis, including the collapse of the kelp forests. After a decade of painstaking research, the pathogen responsible for Seastar Wasting Disease has finally been identified.

Gray Whale mortality

KZYX The Ecology Hour ·

2025/07/09

Gray Whales were once nearly wiped out by commercial whaling. Once that ceased in the late 20th century, they staged a remarkable comeback, reaching a population of around 26,000 by 2016. But since then many have died on migration, and a new estimate indicates their population has been cut in half. We talk with Dr. Aimee Lang of the NOAA Southwest Fisheries Science Center about that estimate, and what might be causing the decline of these iconic marine mammals.

Intraterrestrials - Alien Life on Earth

KZYX The Ecology Hour ·

2025/06/11

Just when you think you've got life all figured out... scientists find something that redefines the whole concept. Ecology Hour hosts Bob Spies and Tim Bray talk with Dr. Karen Lloyd, Professor of Earth Sciences at the University of Southern California, about her research into alien life forms right here on Earth - what she calls "Intraterrestrials" in her new book. Some of these organisms challenge our basic understanding of life: their metabolic processes function so slowly that

Midway Island Albatrosses

KZYX The Ecology Hour ·

2025/05/14

Have you ever seen an Albatross? They are an awe-inspiring sight and there are hundreds of them off the Mendocino coast right now. Many of them are coming here to get food for their chicks, which are more than two thousand miles away, on remote islands in the Hawaiian chain. Ecology Hour hosts Bob Spies and Tim Bray get the whole story from Dr. Jonathan Plissner, Supervising Wildlife Biologist at the Midway Island National Wildlife Refuge, where millions of Albatrosses nest.

Oil Spills: Long-term Biochemical effects

KZYX The Ecology Hour ·

2025/04/09

We hear a lot about the immediate effects of a major oil spill, but what happens later? Our guest Dr. Jeffrey Short is a biochemist who has investigated ecosystem effects of major spills. Working with our host Dr. Robert Spies after the 1989 Exxon Valdez disaster, he discovered that large quantities of oil persisted in the subsurface long after the spill - a finding that was quite controversial at the time. More recently he came out of retirement to work on assessing the damage from the

2025/03/12

Tim Bray and Bob Spies talk with Erin Zulliger of the Institute for Wildlife Studies, who has been studying Elk in northern California. Always an impressive sight, these fascinating animals have a long history here and are currently adapting to changing conditions. Listen to find out more about their lives, their predators, and their populations.

SONAR at Mendocino HS

KZYX The Ecology Hour ·

2025/02/13

Robert Jamgochian and Doug Nunn talk about the SONAR program (School of Natural Resources) they created and ran at Mendocino High School for several years. Students learned how to follow scientific protocols, collect field data, analyze it and write up their findings in scientific reports. Many have gone on to pursue education and careers in environmental law, engineering, or biology. Some were active in getting the Big River estuary included as a Marine Protected Area.

Mantises

KZYX The Ecology Hour ·

2024/11/13

We see them in cartoons as well as in our gardens, but how much do we really know about Praying Mantises? We learn a lot about them from doctoral candidate Lohit Garikipati at the American Museum of Natural History. Originally from California, Lohit became fascinated by these bizarre insects at an early age and has been studying them ever since. They display many amazing adaptations and Lohit relishes telling us all about them.

Domoic Acid

KZYX The Ecology Hour ·

2024/09/20

In the last few weeks, many sick and dying California Sea Lions began showing up on central California beaches, even hauling out at Pier 39 in San Francisco. They were victims of Amnesic Shellfish Poisoning, aka Domoic Acid Toxicosis. What is domoic acid, where does it come from, and why is it affecting so many marine mammals? For answers we turn to Dr. Pádraig Duignan, Director of Pathology at the Marine Mammal Center in Sausalito. He is at the front lines in the response to this outbreak,

2024/09/20

We spoke with Dr. Eric Bjorkstedt of the NOAA Fisheries Ecosystem Science Center. He talked about some of the work being done at the Telonicher Marine Laboratory in Trinidad, Humboldt County,monitoring the offshore marine ecosystem in this little-studied region. Dr. Bjorkstedt gives us an update on current research and some recent findings, including how some key elements of the food web have responded to marine heat waves, as well as the large-scale oscillations of marine weather in the

Cowbirds and Brood parasitism

KZYX The Ecology Hour ·

2024/09/20

Birds invest considerable effort in the reproductive processes and have evolved myriad ways to improve their chances of success. The entire process of mating, nest-building, brooding, and rearing young consumes enormous amounts of energy, often leaving the parent birds nearly worn-out by the time their young reach independence. It is perhaps no wonder, then, that a few birds have developed a way to avoid most of that expense by getting other birds to do most of the work. Brood parasites lay

On the April 2024 episode, we delve into how best to support the environment through charitable giving. We hear from Tom Wheeler, Executive Director of EPIC in Arcata, CA, and from Lawyer Paula Goodwin of Perkins Coie, as well as take a closer look at a number of nonprofits. Check out our Primer for Giving! The show also features music from artist and activists Diane Patterson and Alice Dimicele, featured here with their express permission.

Elephant Seals

We learn about Elephant Seals from Dr. Heather Liwanag, Associate Professor in the Biological Sciences at Cal Poly San Luis Obispo. She studies the physiological adaptations of animals to their environment, and Elephant Seals provide her with many remarkable features to study. The largest and deepest-diving pinnipeds in the world, Elephant Seals can be found on certain California beaches during their breeding season, when the males put on spectacular battle displays. At other times they are

Jet-propelled and able to change color at the speed of thought, they are both predator and prey in every ocean, and the subject of the world's largest fishery. Surprisingly complex, with an evolutionary history going back hundreds of millions of years, they are endlessly fascinating creatures.
