Naturally Speaking – “Should I Stay or Should I Go: Range Shifts in the Tidepools”

Many species are shifting their ranges as a response to climate change. The dark unicorn whelk (Mexicanthina lugubris) is native to the tidepool communities of Baja California, Mexico, but their range has shifted northward over 60 miles into Southern California since the 1980s. While dark unicorn whelk shells have been found in San Diego County dating back to the 1930s and 1950s, it is unknown whether their abundance is increasing, decreasing, or stable over time. Join ecologist Anthony Truong as he discusses his research on unicorn whelks at Cabrillo National Monument and how man-made stressors like climate change affect ecological communities as a whole.

Thursday, December 15, 6:00 PM – 7:00 PM


Please RSVP if you plan on attending.
