You are probably familiar with the "Keep Tahoe Blue" stickers, which have brought public awareness to the decline in clarity of Lake Tahoe's signature blue waters.
But here's a bumper sticker you haven't seen, yet: 'Save Tahoe's Smallest Critters.' Those invertebrates, some only native to Tahoe, are undergoing a massive extinction at the lake's bottom. A group of divers recently completed a first-of-its-kind tour of the entire lake in order to assess the ecological changes there.
Sudeep Chandra is a limnologist at the University of Nevada, Reno, and his team will be studying what those divers found. He spoke with KUNR's Will Stone on Morning Edition.
