The Wandering Naturalist

Our final episode this month goes fully into the vernal pool weeds! Brandon and Ellen bring out their favorite stars of this ecosystem. We talk fairy shrimp, fishing spiders, caddisflies, water boatmen, and backswimmers. For creatures so small, this episode is PACKED with interesting information!

In our second episode we sit down with Dr. Mark Hanson to hear about his research on vernal pools during his career with the Minnesota DNR. We zoom out a bit from vernal pools themselves and learn about their impact on what's around them. From bears to ducklings, these innocuous pools play an important role in the lives of many woodland organisms. This leads us to discuss how forest management impacts the pools and what people can do to keep them safe and healthy.

Time to get your feet wet in the world of vernal pools! This month's topic zooms in on these often overlooked, but crucially important ecosystems. In our first episode we meet with Dr. Darold Batzer, a professor of entomology at the University of Georgia. Dr. Batzer studies the ecology and environmental biology of wetland invertebrates, and gives us an introduction to vernal pools: Who lives in them, what they are, and why they matter.

Jade Ryerson, historian with the Mississippi National River and Recreation Area, wanders with us through time and she shares stories of women who have connected to the Mississippi River in the past and how that impacts us today. From Dakota women involved with diplomacy, to a court case about slavery that helped escalate tensions leading to the Civil War, to a lamplighter who helped Minneapolis and St. Paul commerce develop, women have had deep connections and impacts on the Mississippi River near us.

Wander with us down the Mississippi River as Devin Brown joins us to discuss how her connection to the Mississippi River changed her life. Her first meeting with the Mississippi River happened in Minneapolis as an adult and inspired her to change her career. Since then she has become an avid paddler. More recently she is the first Black woman to attempt to kayak the entire Mississippi River. From its narrow stretch near Itasca to massive cottonwoods breaching like whales during record flooding, her trip was full of amazing stories.

Dr. Peter Kennedy from the University of Minnesota joins us to discuss the latest research on the relationships between plants and fungi. From tree socks to research exchange markets, the interaction between plants and fungi is complicated. What does research really say about this research and what has reporting on this research sensationalized?

Do plants really talk? Not like we do, but Dr. Simon Gilroy, Professor of Botany at the University of Wisconsin Madison, shares the research he and others have done that has shed light on how plants communicate. From leaves hearing and the plant responding, to the smell of fresh cut grass alerting other plants of distress, wander with us as we explore plant communication.

Wander with Brandon and Ellen as they explore how animals communicate. From communication that is obvious to us like sound, to communication we may not have considered such as electricity, animals have complicated ways of sharing information.

Dr. John Anfinson, one of the leading experts on the Mississippi River in our area joins us to talk about the past, present, and future of the Mississippi. He tells us stories of the Mississippi as people tried to navigate the gorge, how its unique geology created the Twin Cities, and why the Mississippi between the Twin Cities was changed into a series of lakes. He also discusses the potential future of the Mississippi River and how you can learn about it and join in the conversation about what the Mississippi should be.

In July, 2025 we had a special Wandering Naturalist rafting trip on the Mississippi River with Brandon. Several participants wore microphones and we recorded the whole experience. Raft with us as we talk to Paula Suchy from Mississippi Gateway Regional Park about how the rafting programs work and why they are so important to her as we listen to audio from our rafting trip.

We start a new season with a new co-host, Ellen, and a new Big Year to celebrate- Big Year of Rivers! Ashley Levoir, joins us to discuss how a big anniversary for the Mississippi River inspired this year's Big Year, plays trivia with Brandon and Angela about the three rivers our park district are named after, and how you can protect our rivers even if you don't live near one.

Every season must come to an end so a new season may begin. A warm and engaging nature expert whose voice we've enjoyed for seven seasons is signing off, ushering in a new era of The Wandering Naturalist. Wander with us as we talk about this big change and what's in store for the podcast for season eight. New and exciting journeys are ahead!

Grace Milanowski, Coordinator, Offal Wildlife Watching Project (with UMN Extension) and Dr. Ellen Candler from the University of Alaska, Fairbanks, talk to us about the project they are doing in partnership with Minnesota hunters to see what visits gut piles from deer. Hunters are participating in citizen science by putting trail cams by their deer gut piles and sending the photos to the Offal project. Grace Milanowski and Dr. Candler discuss some of their findings, including some surprising scavengers of deer guts.

Michael Kurtz, enrolled member from the Lower Brule Sioux Tribe in South Dakota, shares how he taught himself to read animal signs and photograph them. He talks about the experiences with animals he has had following animal signs and how it connects him to the Traditional Ecological Knowledge of his ancestors.

Adrian Iacovino, Education Program Coordinator at Mississippi Gateway Regional Park and professional animal tracker, wanders with us as he recounts how he learned to read the stories left by animal tracks and signs. He shares some of his favorite stories, the community behind tracking, and how listeners can learn to read animal stories. He also discusses how reading animal signs helps him spot preconceived notions in other parts of his life.

Before Basset Creek was named Basset Creek it was named by the Dakota and called Ȟaȟá Wakpádaŋ. Tawnya Stewart, an Ojibwe woman who grew up within a few miles of the creek talks about what it was like growing up in Hennepin County suburbs as a Native person. She explores why the original names of the landscapes are important, why she likes dual naming, and the importance of education when it comes to bringing back something's original name.

Dr. Kasey Keeler wanders with us to discuss her personal experience and her professional research on life in the suburbs as a Native American in Hennepin County. We discuss what it is like growing up as a Native person in the suburbs, how access to nature can be improved, and why suburbs are often overlooked as Native places.

Paul Bunyan and Babe the Big Blue Ox are classic stories in Minnesota culture. Where did these stories originate from? How are they connected to Ojibwe culture and history? How have these stories shaped our views of history? Dr. Deondre Smiles discusses his research on the origin of Paul Bunyon stories and the impacts it has had on Ojibwe life.

OK, slime molds don't write. But amazing things have been written about them, allowing us to appreciate their wonder, explore societal ideas, and inspire future scientists. Dr. Lacy Johnson, from Rice University in Texas joins us to discuss why she chose to write a creative writing essay on slime molds and why she views creative writing as essential to science communication.

How is intelligence defined? If you define it as learning and applying knowledge, then slime molds are intelligent. How did scientists determine this? How is a single celled organism with no brain or sensory organs able to experience its world and learn from it? Dr. Nirosha Murugan from Wilfrid Laurier University in Ontario Canada wanders with us to discuss research about slime mold intelligence, and maybe even a cyborg future. This may be Brandon's favorite episode ever!
