Describe the experiments performed by Luc De Meester (1996)to demonstrate phenotypic plasticity in the response of several Daphnia genotypes across a wide range of environments.Be sure to include (1)the experimental method used to measure the change in phototactic behavior and the use of reaction norms,(2)the types of treatments performed based on water that had been previously occupied by fish,and (3)the reaction norms observed from Daphnia eggs harvested from sediments from differing environments.
