Fellows' Science Day 1997
           Saturday, February 22, 1997, 9:00 A.M. to 4:30 P.M.

            "Alien Species of the San Francisco Bay-Estuary:
                 History, Consequences, and Prospects"

 On Saturday, February 22, 1997, the California Academy of Sciences
 will hold its annual Fellows' Science Day. This year's program
 concerns alien species of the San Francisco Bay-Estuary. Nine
 principal speakers will present technical and timely summaries of
 their work on the history and ecological consequences of the
 inadvertent, and the purposeful, introduction of non-native plant and
 animal species to the bay-estuary system. These presentations will be
 followed by a roundtable discussion concerning management of the alien
 species, and the role of science in guiding that management. The
 program will include the following speakers and topics:

    * Dr. James Carlton, Williams College, Mystic, Connecticut
      "Biological invasions in the sea: the global and historical context"
    * Dr. Andrew Cohen, University of California, Berkeley
      "San Francisco Bay: the invaded Estuary"
    * Dr. Michael Barbour, University of California, Davis
      "Non-indigenous plant species of the San Francisco Bay-Estuary System"
    * Dr. Fred Nichols, United States Geological Survey
      "The impact of the introduced Asian Clam, Potamocorbula
      amurensis, on the food web of northern San Francisco Bay"
    * Dr. Donald Strong, Bodega Marine Laboratory, Bodega Bay
      "Spartina and its impact on the ecology of the San
      Francisco Bay-Estuary System"
    * Dr. Bruce Herbold, U.S. Environmental Protection Agency, Dixon
      Title to be announced
    * Dr. Jonathan Geller, University of North Carolina
      "Molecular genetic analysis as a means of tracing the
      geographical origins of introduced species"
    * Dr. Armand Kuris, University of California, Santa Barbara
      "Biological control of introduced marine pests"
