Cumulative numbers of viable offspring produced by uninfected and P. ramosa -infected D. magna . a) Animals raised on different food sources directly. b) Animals raised exclusively on S. obliquus, but mothers raised on different food sources. Shaded areas indicate the proportion of total offspring produced after the sterile phase (castration relief). Error bars indicate s.d. Bars labelled with the same letters are not significantly different (general linear hypothesis testing, p < 0.05 following GLM).
