Growth of Daphnia magna in the laboratory in relation to the nutritional state of its food species, Chlamydomonas reinhardtii

Growth rates and fecundities of Daphnia magna in the laboratory were higher, and mortalities were lower, when the animals were fed on log-phase cells of Chlamydomonas reinhardtii than on nitrogen- or phosphorus-limited cells. The effect appears to be related to the nutritional adequacy of the algae,...

Description
Summary:Growth rates and fecundities of Daphnia magna in the laboratory were higher, and mortalities were lower, when the animals were fed on log-phase cells of Chlamydomonas reinhardtii than on nitrogen- or phosphorus-limited cells. The effect appears to be related to the nutritional adequacy of the algae, rather than to their production of toxic or inhibitory substances, but it was not related directly to their nitrogen content or growth rates.
