    Season 5 | Audio Footprints
    Oct 28 2026
    Bats of all kinds in northern North America have been struggling with white-nose syndrome for two decades, now. Researchers in Acadia National Park and Katahdin Woods and Waters National Monument are doing their best to track the situation, and they’re using nets and microphones to do it. In this episode we get up close and personal with bats and the sounds they make, including their unique echolocation calls—their ‘audio footprints’, if you will. Never heard a bat echolocate before? You’re in for a treat.

    Season five of Sea to Trees is just around the corner, and we have an excellent cast of characters. We have appearances from no less than three Acadia Science Fellows, Schoodic Institute’s own Nick Fisichelli, and… my mother’s coworker? She’s actually a great help. Tune in this winter for episodes covering endangered bats, spruce trees, and the history hidden under Acadia’s shorelines.

    Place-based Science | The Coastal Spruce Fir Forest
    Feb 18 2026
    Along the coast of Maine a special cold-adapted forest ecosystem thrives: the coastal spruce fir forest. The cool air that blows off the ocean provides an ideal environment for these colder species, but their future, like many, is uncertain. In this episode, we’re traveling through time to understand how coastal spruce fir forests in Acadia have changed over the past sixty-six years.

    Past, Present, and Future | Ferrying Frogs and Measuring Mice
    Dec 17 2024
    During warm, wet nights in early spring, thousands of amphibians shake off their winter grogginess and take to the roads. Hardy small mammals scamper along the forest floor and make extensive homes within the cracks of Acadia’s mountains. Some of the park’s smallest creatures, that play outsized roles in nature’s food web, are also some of its most mysterious. Learn about two survey projects asking what it’s like to take the pulse of Acadia National Park on Season 3 Episode 3 of Sea to Trees.

    Past, Present, and Future | How Fame Changed MacArthur’s Warblers
    Nov 20 2024
    In 1956, Robert MacArthur sat in a spruce-fir forest of Acadia National Park and tried to understand the truth behind warbler diversity. How could there be so many different species coexisting, when theory seeks to crown “one warbler to rule them all?” Learn about MacArthur’s study, how it changed the field of ecology, and the scientists revisiting his work over half a century later on Season 3 Episode 2 of Sea to Trees.
