Under the Microscope: Asian carp, monarch migration

Water experts in the Midwest are worried about Asian carp. They say the invasive fish are taking over U.S. waterways -- the Mississippi River and its tributaries like the Illinois and Missouri Rivers, where they out compete native fish.

But as Jacob McCleland reports for Harvest Public Media, river watchers at their wits end have found new hope. And it lies on dinner tables in China.

Monarch butterflies are in trouble. The latest estimates show their numbers have dropped dramatically at their wintering grounds in Mexico.

Ecologist Lincoln Brower has been studying these large black-and-orange insects for close to 60 years.

He was recently in St. Louis to accept the Harris Center Conservation Action Prize from the University of Missouri-St. Louis and spoke to Véronique LaCapra about monarch butterflies and their remarkable international migration.
