Daphnia salinity report

WebDaphnids were exposed for 2 to 21 days to salinity in a variety of water-only tests, in tests with freshwater sediment overlain by salt water, and in tests with estuarine sediments overlain by freshwater. Daphnid age, test length, and temperature seemed to have little effect upon the range of LC50, NOAEL, and LOAEL values. WebOnce the surviving Daphnia were counted, the group made a chartcomparing the survivors to the salinity concentrations. Results and DiscussionFigure 1: Number of survived Daphnia in different salinitiesThe data above shows how many of the Daphnia survived in each of the different saltconcentrations.
