Grass Valley, CA, September 4, 2018 – Find out how climate change has effected butterflies living in our area in this fascinating, free presentation given by Professor, Dr. Art Shapiro. The presentation will be held on Tuesday evening, September 11th from 6:30 – 7:30 pm, in the Multipurpose Center, building, N-12 Room 103, at the Nevada County Campus. Come early and enjoy a meet-and-greet and refreshments at 6:00 pm.

Dr. Shapiro describes his presentation this way; “We have monitored entire butterfly faunas at 10 sites along the I-80 corridor anywhere from 30 to 45 years—a total of 163 species–which has provided one of the most detailed data bases in the world for inferring biological impacts of climate change. Looking at different time scales, we can separate short-term fluctuations (“noise”) from long-term trends (“signal”). Here’s a short summary of what we’ve learned so far. There are a lot of surprises.”

Dr. Art Shapiro is currently a Distinguished Professor of Evolution and Ecology and Zoologist in the Agricultural Experiment Station at UC Davis, where he has been teaching since 1971. His accolades include: Fellow, AAAS. Fellow, CA Academy of Sciences. Fellow, Royal Entomological Society (UK). Fellow, The Explorers Club. Author of over 300 scientific papers and book: “Field Guide to Butterflies of the San Francisco Bay and Sacramento Valley Regions,” UC Press, 2007. Dr. Shapiro graduated with a BA from the University of Pennsylvania, (Biology) and a Ph.D., from Cornell University in Entomology.
