Table 2. Comparison of filtering rates of individual mussels exposed to Sylvan Slough porewaters as determined 

 with the change in yeast control concentration (eqn. 1) and without the change in the yeast controls (eqn. 2). 

 Filtering rates have units of mg yeast ■ g dry wt" 1 - musselh'. The negative filtering rates were considered not to be 

 "'realistic" of "'true" filtering rates. Positive filtering rates resulted after eliminating the change in yeast 

 concentration from the yeast controls from the equation.
