  • Introduced is back for Season 3! In this episode, we explore the names we use for invasive species. How do species get their names? And what real-life consequences can these names bring?

    Transcript available here.

  • SPECIAL ANNOUNCEMENT: Introduced will be returning for a new season in 2024!

    But in the meantime, we're sharing a fascinating, fishy episode from our friends at Points North, an award-winning podcast about the land, water and inhabitants of the Great Lakes.

    In October 1960, Prince Akihito of Japan visited Chicago for 21 hours. Chicago’s mayor presented the prince with a diplomatic gift: 18 bluegill. What happened next would change the underwater world of Japan forever.

  • Today, we’re introducing a new podcast from Wisconsin Sea Grant called The Water We Swim In, which features stories about the Great Lakes and the people working toward equity.

    On “Hidden Currents,” Bonnie Willison and Hali Jama dive beneath the water to explore why Black children are drowning more than any other race, why marginalized communities often lack access to swimming pools, and how to stay safe in the water. We hear about the alarming trend facing swimming pools in cities across the nation, relive a fight to save one Milwaukee pool, and walk the shores of Lake Michigan with the Beach Ambassador program. Join us as Brenda Coley, Jumana Tanner, Cheryl Bledsoe, Sally Callan, and Deidre Peroff discuss how racism, segregation and redlining has taken away Black people’s access to water and, essentially, the right to swim.

  • Today, on the last episode of season two, we’re talking about climate change, which threatens to upend everything western science understands about native and invasive species. First, we join the Great Lakes Indian Fish & Wildlife Commission climate change team as they carefully observe the seasonal relationships between all the beings in the forest. Then we talk to the Tribal Climate Adaptation Menu team, who are helping tribal nations find ways to assert their knowledge and adapt to climate change. Finally, we step back 20,000 years to see what paleoecology can teach us about how species move as the climate changes.

  • This week, we dive deep into two news stories that flew under the public’s radar. In the summer of 2020, individuals all over the country started receiving random packages of unsolicited and unidentified seeds. In the spring of 2021, pet stores around the country found that the moss balls on their shelves carried a notorious aquatic hitchhiker. On this episode, we talk to some of the people who devoted months of their lives to dealing with these first-of-their-kind international crises.  

    Special thanks to our guests Christopher Deegan, Wesley Daniels, Amy Kretlow and Amy McGovern.

  • The miniscule Spiny waterflea was introduced into Madison’s Lake Mendota and lurked undetected for years. This hour, Bonnie and Sydney take a new look at a well-studied lake and try to figure out how an introduced species can float below science’s radar for so long.

  • Who gets to decide where a species belongs? What does it mean for something to be “invasive?”

    The term “invasive species” is commonly used by researchers and academics. But as the authors of the Dibaginjigaadeg Anishinaabe Ezhitwaad – A Tribal Climate Adaptation Menu developed the indigenous resilience guide, they spent long hours reckoning with the term “invasive,” along with a slew of other Western terms like “climate change” and “management.” Next, we speak to scholar Paul Robbins, whose personal journey with invasive species started with a flat tire in Rajestan, India. Since then, he’s studied human interactions with nature and the politics of natural resource management. Lastly, we join a group of reptile and amphibian experts who are debating if a popular pet turtle species, the red-eared slider, should be listed as prohibited or restricted in Wisconsin’s invasive species law.

  • We’re excited to share an episode of Teach Me About the Great Lakes featuring the Introduced team! This episode is all about invasive species generally, and invasive crayfish specifically. TMAGL speaks again with Dr. Brian Roth about his work on invasive crayfish and with IISG’s own Greg Hitzroth about the Invasive Crayfish Collaborative. Plus, in a special bonus, we speak with the hosts of Introduced, a highly produced, episodic podcast about invasive species from our colleagues at Wisconsin Sea Grant.

    Today’s guests are Dr. Brian Roth of Michigan State University, Greg Hitzroth of Illinois-Indiana Sea Grant, and the producers of the Introduced podcast: Bonnie Willison, Sydney Widell, and special guest Tim Campbell.

  • Wisconsin Sea Grant takes a trip to the world’s largest electric fish dispersal barriers, just south of Chicago. These barriers are sending electricity into the canal for one purpose- to keep Asian Carp from swimming into the Great Lakes.

    EDIT: In this episode, we state that the dense and reproducing carp population is 20 miles downstream of the electric carp barriers. This is incorrect – the dense and reproducing Asian Carp population is located 100 miles downstream of the barriers in the Peoria and La Grange pools of the Illinois River.

    Special thanks to our guests Duane Chapman, Tim Campbell, Kevin Irons, Elena Blevins and Titus Seilheimer. Thank you to the US Army Corps of Engineers and Chuck Shea for a tour of the electric barriers.
