Correlated phenotypic responses to selection. All scores are pooled across three successive generations. Lines with the same letter are not significantly different from one another at P < 0.05. H lines are red, C lines are yellow, L lines are blue. Solid lines and bars represent replicate 1, and dashed bars and lines denote replicate 2. The red asterisk denotes each line is significantly (P < 0.05) different from each other, and the black asterisk denotes H lines and C lines are not significantly different from each other, but are significantly different than L lines. (a) Starvation resistance, (b) chill coma recovery, (c) ethanol tolerance, (d) copulation latency, (e) behavioral locomotor senescence.
