Water content of individual adult Drosophila melanogaster following LT50 exposures at each of six temperatures compared with desiccated and hydrated control flies. Percentage of water (mean ± s.e.m.) was measured by subtracting dry mass from wet mass, dividing by wet mass and multiplying by 100. Bars labeled A were not significantly different from hydrated flies (Tukey's post hoc test, P>0.05). Bars labeled B were not significantly different from desiccated flies (Tukey's post hoc test, P>0.05). Bars labeled A,B were not significantly different from hydrated or desiccated flies (Tukey's post hoc test, P>0.05). Unlabeled bars were significantly different from both hydrated and desiccated flies (Tukey's post hoc test, P<0.05).
