Blind shrimp and stoneflies.
Researchers from the University of Nevada, Reno and UC Davis have recently found that substantial change has occurred at the bottom of Lake Tahoe over the past four decades. What is happening on the lake bottom and what changes are being found in the plant and animal communities that inhabit deep areas of the lake?
What is causing this change and how will it impact the overall health of the lake?
The team of scientists and volunteers initiated a comprehensive investigation of the lake bottom (the first since the 1960s). They used dredges to collect 400 samples from deep areas of the lake to detect changes since the 1960s survey. Looking for elusive native species, they found critters that live only in Lake Tahoe.
These species include a blind shrimp that normally lives in dark caves and a stonefly that, unlike other stoneflies, lives its entire life in the lake. Meet these interesting species and learn why they might be the “canaries in the coal mine” for the health of Lake Tahoe.
