Introduced University of Wisconsin Sea Grant Institute

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. 
Thank you to our guests Rob Croll, Hannah Panci, Sara Smith, Jerry Jondreau and Jack Williams.

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.

On August 27, 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.

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.
