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!

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.

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.

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.

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.

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.

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.

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.

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.

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.

What is a slime mold? It is an inconceivable single celled organism that can weigh up to 40 pounds, think and learn, and crawl around the forest floor searching for food. How can a single celled organism be 44 pounds, learn, and move? Matt the Regular Slime Guy joins us to help introduce us to what a slime mold is and how such an inconceivable creature lives its life.

How do you restore wild rice to an area? Steven Hogg, Senior Manager of Wildlife at Three Rivers Park District, talks about the work done to bring back wild rice. From sourcing seeds, to distributing them, and making sure it grows Steven talks about the challenges, what he's learned, and how the restoration is going at Three Rivers.

Dr. Adam Berland from Ball State University joins us to talk about research on why trees are important for people in an urban environment. He also talks to us about the surprising conclusions from his research in Minneapolis on how urban foresters can plant trees to prevent future large die offs from climate change and invasive species such as we've seen from Ash trees with Emerald Ash Borer, and Elm trees with Dutch Elm disease. He gives some advice on how you can choose trees that will help increase the resilience of trees to stress in the area.
