Tiburon Laboratory: Invasions and Community Ecology on the US West Coast
Our core mission is to track the pulse of biotic change in the estuaries and coastlines along the Pacific Coast of North America. We identify non-native species in San Francisco Bay and surrounding coastlines, from Alaska to Panama, learn how their life cycles work in these new environs, and determine what effects they might be having on resident communities. We seek, in short, to make the consequences of moving species to strange new oceans both known and predictable, including how these species will interact with changing climate regimes.
Since 2000, our researchers have maintained a laboratory on San Francisco Bay, at San Francisco State University’s marine research and teaching facility, the Estuary & Ocean Science Center (EOS). A 2013 Memorandum of Understanding between the Smithsonian and San Francisco State University expanded our relationship and signified our joint commitment to understand and protect the marine environment. With our colleagues at RTC and the San Francisco Bay National Estuarine Research Reserve, we are excited to be part of a community of researchers engaged in working out the effects of global change, invasions, and many other pressing issues in truly complementary fashion.
We have undertaken intensive, long-term studies of marine and estuarine communities across several habitats in California and especially San Francisco Bay, including hard substrates (fouling), soft sediment benthos, and plankton. We have used settlement panels to study fouling community development and invasion impacts since 2000 as part of an international effort to understand and document patterns of the species distributions and invasion in marine coastal waters. Recent studies have paired traditional morphological approaches to species identification with genetic approaches (with our collaborator, Dr. Jonathan Geller) to get a more complete picture of the species in California bays and near-shore environments.
Vessels of all kinds move species within and between bays. Our scientific divers conduct in-water hull surveys of boats and ships in West Coast ports and beyond to assess the role of vessel biofouling in moving organisms from port to port. Read more about our work on cargo and cruise ships in the Smithsonian Magazine.
We have studied ways to make eradication of targeted non-native pest species more efficient and effective, and have undertaken numerous eradication efforts, including the Japanese Mudsnail (Batillaria attramentaria) and the colonial tunicate Didemnum vexillum. Most recently, we worked with UC Davis and NOAA to monitor and eradicate a local population of non-native European Green Crabs (Carcinus maenas) near Stinson Beach, CA, and have investigated the possibility of functional eradication of the Atlantic oyster drill (Urosalpinx cinerea) as part of native Olympia oyster restoration efforts.
Native Olympia Oysters
We collaborate with a number of agencies and research facilities to investigate native Olympia oyster (Ostrea lurida) demographics along California’s shorelines. Using a rigorous combination of field surveys, laboratory experiments, and population modeling, we examine the influence of environmental factors, climate change, and non-native species on the distribution and abundance of native oysters. We are also investigating oyster enhancement and restoration methods in San Francisco Bay and Elkhorn Slough.
Citizen scientists form an essential and dedicated component of our research efforts. We run a citizen science network (PlateWatch and Green Crab Watch) to monitor for target non-native species along the Pacific Coast from Alaska to California. Participants include scientists from local state and federal agencies, concerned citizens, school groups and native groups. Within San Francisco Bay, we run citizen science programs to track Olympia oyster recruitment and the movement and predatory effects of the introduced snail Urosalpinx cinerea. If you wish to participate in any SI Citizen Science program, please contact Allison Cawood for more information at email@example.com.
We mentor interns and students in a wide range of capacities, and we usually host several undergraduate interns each summer. Our interns come from STAR and REU programs at San Francisco State University as well as the Smithsonian Internship program, which includes an REU program and numerous other opportunities. Each student participates in major lab projects as well as designs and executes an individual research project. Please see each program for their requirements and how to apply.
