A. Technology Helps Researchers Track the Elusive Mountain Lion

Narrator: This is Science Today. Wildlife experts at the University of California, Davis have been studying the inter-relationships between mountain lions and people and the other wildlife that mountain lions share their habitat with. Walter Boyce, director of the university's Wildlife Health Center, leads this long-term research project.

Boyce: All of us that have hiked and played in mountain lion habitat have undoubtedly been watched by mountain lions. But they're typically hiding under a bush during the daytime when we're out there, so we don't really know what they're doing.

Narrator: The researchers now track mountain lions using satellite GPS collars.

Boyce: The satellite collar will determine the animal's locations and we program these to collect locations early morning, midday, late afternoon, during the night. The collar stores that data and then sends it to us. We get the data once a month, then we plot that on a map and from that, we're able to determine where the animals had been on a day-to-day basis where they're spending more time and less time, their most frequent travel routes and the clusters of locations.
