Introduced – Details, episodes & analysis

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?

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.

Pacific salmon were introduced into the Great Lakes to control nuisance alewives. Now, alewives and salmon are both being challenged by a new wave of introduced species.

Even the smallest snails can mean big changes for the region’s lakes and streams. We visit the Fond du Lac Band of Lake Superior Chippewa, where mystery snails encroach on wild rice, and track the spread of New Zealand mudsnail across Wisconsin trout streams.

Smelting became a beloved tradition after rainbow smelt were introduced into the Great Lakes. How did smelt get introduced, how do they fit into the food web and what happens when humans fall in love with a non-native species?

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.

On August 25, 2009, the Wisconsin Department of Natural Resources gets a call about small lobsters crawling around a neighborhood pond in Germantown. The extent of the problem is more than anyone bargained for. Here’s the story of the first red swamp crayfish introduced into Wisconsin.
