In a bid to reverse this disturbing trend and conserve this clearly vulnerable

Abstract The population dynamics of Daphnia magna are observed under three different conditions; low‚ medium‚ and high density. The effects of different population densities on the survivorship and reproduction of Daphnia are observed over a two-week period within a lab environment. Over the two week period‚ the numbers of parent Daphnia alive and dead are recorded daily‚ along with the amount of offspring produced each day. From the main parameter investigated‚ the net reproductive rate‚ the
