Condition indices of three species of bivalves
at their original "reference" locations, prior to
deployment (T-0), and at the end of their exposure
to San Francisco Estuary waters (various locations)
during the wet and dry seasons of 1997. Bivalves
deployed at the Dumbarton Bridge (BA30), Redwood
Creek (BA40), and Red Rock (BC61) stations during
the wet season did not survive (indicated by ).
Bivalves were not deployed at the Davis Point (BD50)
station in the wet season (indicated by ).
Surviving bivalves retrieved from the Napa River
(BD50) and Yerba Buena Island (BC10) stations during
the wet season and the Davis Point (BD40) station
during the dry season were allocated to trace elements
and organics analyses (indicated by ).
Bars indicate the range of values. |
