Results of the chronic exposure of D. magna to sparteine on endpoints related to the neonates: a) Cumulative reproduction of neonates from each treatment group over the 21-day exposure period. Data is the cumulative mean number of neonates per mother for each treatment on each day; b) Mean number of days to production of first brood,  ± standard error; c) Mean cumulative number of neonates per mother by 21 days,  ± standard error; d) Mean length of neonates (mm),  ± standard error. Small letters signify significant differences between treatments (For figure 3b Kruskal-Wallis one-way ANOVA on ranks followed by an unadjusted Dunn’s test; 3c and 3d one-way ANOVA followed by a Tukey HSD test)
