What are the effects of salinity/acidity levels on Daphnia magna feeding response? NOTE: We do not have to do both of these. I just wanted to give us a little leeway to change our minds about the direction of the proposal. Intro: Many aquatic organisms can be sensitive to even subtle changes in their environment especially in terms of changes in pH and salinity. Daphnia has a tendency to be a fairly hardy (Mart ´nez-Jero´ nimo ı ). Most species of Daphnia are found in mostly freshwater, moderately acidic, large bodies of water such as lakes or swamps. There are some species of Daphnia that are more tolerant of higher concentration of acids and salts in their environment (HEINE-FUSTER I), while other species have been known to develop saline tolerance after exposure. With changing climate conditions and environmental pollutants it is very likely that many aquatic species will at some point become exposed to variances in their habitats. Daphnia are considered by some to be an indicator species for their
