Extended quiescence significantly reduced female adult dry body mass at time of emergence by 21% (one tailed t test, p<0.0001, t=11.83 df=95). Larval metal stress reduced adult body size 17.3% in short quiescence females while only 11.4% in extended quiescence females representing a significant difference in metal physiology response between short quiescence and extended quiescence females (one tailed t test, p<0.05, t=7.083 df=117)(Fig. 1). (short-q=short quiescence, ext-q=extended quiescence) (white columns – reared in clean water; black columns-reared with metal stress) (n~50-60).
