When <a href="https://www.sciencefriday.com/segments/lewis-clark-wildlife-survey-animal-tracking?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri?" target="_blank" rel="noopener noreferrer">Lewis and Clark</a> crossed the United States in the early 1800s, they recorded their wildlife observations along the way. Now, more than 200 years later, an expedition is following the same route and partnering with scientists across the U.S. to catalog animals and track the changes. Expedition leader Roland Kays joins Host Flora Lichtman to share some highlights.
Plus, using cell phone data and GPS collars, ecologists were able to see how animals moved (or not) when people were around. Ecologist Ruth Oliver tells us about her findings.
Guests:
Dr. Roland Kays is research professor at NC State University and director of the Biodiversity & Earth Observation Lab at the North Carolina Museum of Natural Sciences.
Dr. Ruth Oliver is an ecologist and assistant professor at UC Santa Barbara.
