摘要：

Age and size at maturity are among the key traits of life-history evolution in Daphnia. Growth data from one clone of Daphnia magna show that there is a threshold size above which maturation is initiated. This threshold mechanism regulates body length at maturity at the cost of age at maturity. A model explains how the threshold accounts for large variation in age and size at maturity.
