Data from the meta-analysis

Data collected from 6 studies and our 5 maternal effects experiments. study = study identity (see figure 4, mean text), species = species of Daphnia, clone = identity of clone line, tox.prop = toxicity as the proportion of cyanobacteria in the food (measured as the fraction of total organic carbon weight per liter medium), tox.conC = toxicity as the concentration of cyanobacteria (measured as mg of organic carbon per liter of medium), tox.conM = toxicity as the concentration of microcystin (ug/L), trait = description of trait, tr.cat = trait category (see figure 4 in main text), stat.type = type of statistic (t = t-test, z = z-test, OD = odd ratio), stat = value of statistic, df = degrees of freedom, direction = direction of effect (C = offspring from control mothers have higher mean, M = offspring from exposed mothers have higher mean), mnC = mean offspring control mothers, sdC = standard deviation offspring control mothers, seC = standard error offspring control mothers, nC = sample size offspring from control mothers, mnM = mean offspring exposed mothers, sdM = standard deviation offspring exposed mothers, seM = standard error offspring exposed mothers, nM = sample size offspring from exposed mothers, pooled.sd = pooled standard deviation, cohens.d = Cohen’s d, var.cd = variance for Cohen’s d, hedges.g = Hedges’ g, var.hg = variance for Hedges’ g, effect = effect size (Hedges’ g corrected for the direction of the effect), sid = study identity number, cid = clone identity number, tid = trait class identity number
