Three features of the clone were essentially invariant with respect to food level: the length-mass regression, the durations of instars, and the size-specific fractions of net energy intake invested in reproduction. The main response to food limitation was a reduction in size-specific net energy intake and in egg size. The energy cost of molting is a major constraint on the evolution of body size in Daphnia. -from Author
