More than 20 years ago, an accidental ecological experiment began when the infamous drug lord, Pablo Escobar, died and his private collection of exotic wildlife wandered off his compound in Antioquia, Colombia. The hippos that were part of that collection have now reproduced and their population has grown and appears to be thriving in the water-rich Colombian rainforest. Listen in to an interview with WBEZ's Worldview where Dr. Rebecca Lewison shares her knowledge of hippos and discusses what to make of the hippos of Colombia.

Research in the lab has long been focused on understanding landscape and seascape connectivity - how animals move, or don't move, across the landscape. From desert tortoises and bobcats, to sea turtles and sharks, a number of projects are working to improve tools and approaches to understand how animal movement patterns over time are shaping the populations we observe.
