#12 – A Salmon Habitat Mosaic: Why Glaciers and Volcanoes Matter to Fish

Grab all the foul-weather gear you can find—in this transmission, you’ll trek across a tumultuous landscape in search of resilience strategies for wild Alaska salmon. Sponsored by Acme Smoked Fish. Ice-age glaciers, volcanoes, tectonic motion, windstorms, and flooding are all part of the package when it comes to salmon’s biggest defense against climate change: genetic diversity. While Alaska is home to five species of Pacific salmon, its genetically-distinct stocks number in the hundreds of perhaps even thousands. With subtle differences in appearance and behavior, these robust populations embody what scientists call the “portfolio effect.” What does this mean and how can it help salmon remain climate resilient? Find out as you enjoy a soundtrack of immersive sounds and musical interludes that take you from the placid lakes of Alaska’s Bristol Bay region to the rushing rivers of Southeast. Then, read Sockeye 101 at www.acmesmokedfish.com. The SeaBank Chronicles is a natural sound theater transporting you through the living science of Southeast Alaska.
