We know that climate change is dramatically and adversely affecting habitats of many endangered species, but it is also skewing the male-to-female ratio of certain animals. Today on River to River, we talk with two Iowa State researchers who study how climate change may halt the sexual reproduction of turtles, lizards and fish due to a lack of males.

Also, we sit down with Chris Brochu, an Associate Professor of Geology at University of Iowa to discuss recent research on the death of the dinosaurs that is making waves in paleontology.

A replica of a rare, 67,000,000-year-old dinosaur fossil is in Iowa for a little while. “Sue" the T-Rex was discovered in South Dakota in 1990.

The Science Center of Iowa is hosting a traveling exhibit about the dinosaur Feb. 2 to May 12. Workers have been busy this week setting up the replica of the towering fossil.

That’s where IPR's Sarah McCammon caught up with the Science Center’s exhibit director, Allison Shwanebeck, and Michael Paha of the Field Museum in Chicago.

This weekend the annual alternative music festival Eighty Thirty Five marks it’s fifth consecutive year of bringing national acts like Avett Brothers and Death Cab for Cutie to Des Moines.  For some these are new and unusual bands and festival organizers say this is one of the key reasons they put together this music event.
