Welcome back to part 2 of our thermophiles in Yellowstone conversation! If you haven’t tuned in to part 1 first, I recommend pausing this episode and hopping into the previous one to learn the basics about the terrific thermophiles.

I’m excited to continue our conversation with Dr. Eric Boyd and dive deeper into the world of thermophiles. Did you know that a thermophile species discovered in Yellowstone has been used in important scientific discoveries related to crime scene investigation? If you’re an avid true crime podcast listener, you’ll definitely want to stick around to learn about that discovery and application. We’ll also cover how thermophiles played a role during the Covid-19 pandemic, what could still be waiting to be discovered in Yellowstone’s thermal features, and get into some great listener questions submitted by our podcast insiders.

Alright, let’s continue this burning conversation about thermophiles.

The Greater Yellowstone Ecosystem is the land of 49+ Indigenous Tribes who maintain current and ancestral connections to the lands, waters, wildlife, plants, and more.

Voices of Greater Yellowstone was created by the Greater Yellowstone Coalition, a conservation nonprofit dedicated to working with people to protect the lands, waters, and wildlife of the Greater Yellowstone Ecosystem, now and for future generations.

The Greater Yellowstone Ecosystem is known for a lot of big things. Charismatic megafauna like bears and bison, expansive forests as far as the eye can see, and mountain ranges that seem to touch the sky are all found in this unique region. However, did you know that the Greater Yellowstone Ecosystem is also home to some of the most fascinating microbes found on the planet?

Enter thermophiles: microscopic creatures found in Yellowstone’s geothermal regions that thrive in scalding hot temperatures. The name thermophile comes from the Greek word thermē meaning heat and the Greek word philos meaning love or an affinity for something. They’re not often the stars of the show when it comes to visiting the park, but these thermophiles are at the center of some of the most interesting stories and scientific discoveries in a national park. After listening to this conversation, we hope that even the greatest Yellowstone experts can head into the park armed with a new subject to explore.

Joining us on the podcast is Dr. Eric Boyd, a professor of environmental microbiology at Montana State University. For the past 20 years, Dr. Boyd has studied the microbiology and geochemistry of the thermal features in Yellowstone National Park to better understand the processes that support diverse microbial ecosystems in high temperature environments. He’s also authored over 190 scientific articles on extremophilic microorganisms, which live in environments with conditions approaching or stretching the limits of what known life can adapt to such as temperature, pressure, salinity, and pH level. If you want to learn about the incredible thermophiles found in Yellowstone, Dr. Boyd is your guy.

We chatted for quite a while so we’ve split this episode into two parts. In this episode, part 1, we’ll take a deep dive into what exactly a thermophile is, how thermophiles are able to thrive in these crazy hot conditions, how Dr. Boyd collects thermophiles in the park—including some interesting methods for Old Faithful—and much more.

I can’t wait for you to learn more about this “hot” topic!

Is there any fish species in the Greater Yellowstone Ecosystem more iconic than the Yellowstone cutthroat trout? While the name conjures imagery of a ruthless nature, these fish are called cutthroats due to the distinct red markings found along their jawline and gills. Yellowstone cutthroat trout are a keystone species in the region, providing food to numerous species including bears, otters, ospreys, and others.

Yellowstone cutthroat trout are also at the epicenter of one of the most interesting species recovery stories from the Greater Yellowstone Ecosystem. Decades ago, when an unexpected threat appeared in Yellowstone Lake, the population of Yellowstone cutthroat trout in the park was decimated. This important link in the Greater Yellowstone food web was in big trouble and something needed to be done.

We’re pleased to welcome Andi Puchany, a fisheries biologist at Yellowstone National Park, to the podcast. She joined the park’s Native Fish Conservation Program in 2014 and her work focuses on native fish conservation, population recovery assessments, and lake trout reproductive ecology. Andi received her Bachelor’s in Zoology at North Dakota State University and her Master’s in Fish and Wildlife Management at Montana State University.

Join us on the episode to learn how to identify a Yellowstone cutthroat trout, what happened all those years ago to cause a decline in Lake Yellowstone, how these remarkable fish rebounded, and what makes her hopeful about her work today.
