Abstract
1. Under certain conditions carbon dioxide may be employed to suppress completely the production of male young by crowded Cladoceran mothers. 2. Under conditions presumably associated with depression periods carbon dioxide is wholly ineffectual in the suppression of male production. 3. Lack of food, accumulation of waste products and alterations of the hydrogen-ion concentration of the medium have been advanced as possible causes of depression periods in Cladocera, but it is probable that many other factors are also associated with the phenomenon.Keywords
