WebDaphnia magna, the largest Daphnia species, is often used as model organism in ecological, evolutionary or ecotoxicological studies (Miner et al., 2012). Daphnia females … WebAlso, Daphnia magna is both ectothermic and poikilothermic, which means that its body temperature and therefore its metabolic rate are affected directly by the temperature of the environment. The change in metabolic rate is reflected in the rate at which the heart beats. For most endothermic and ectothermic biological systems involving enzyme ... optics1 slamd
