From tracking tigers in Nepal to mountainside surgery on Montana’s wolverines, Deborah McCauley (VIEW) is on a mission to save disappearing wildlife around the world.

And: Rowan Lockwood (William & Mary) is taking a closer look at the fossils of giant oysters to learn how to rebuild oyster reefs today.

Later in the show: Crystal blue lakes might make for a popular tourist spot, but they’re starting to disappear. Dina Leech (Longwood University) is studying what gives lakes their color and why they’re changing.

Plus: While forests are a deep green right now, in just a few months leaves will be changing colors--thanks, in part, to caterpillars. Rebecca Forkner (George Mason University) shares how these tiny insects change their environments and what we can learn from them.
