FIG. 4 in Predators Induce Morphological Changes in Tadpoles of Hyla andersonii

FIG. 4. Box and whisker plots showing range of tadpole tail mean gray values (a measure of tail darkness). Lower mean gray values indicate darker tail coloration. (A) Day 32 (þpredator treatment mean gray value6SD ¼ 92612.82; –predator control ¼ 103.8868.54), (B) Day 39 (þpredator ¼ 93.11615.22; –predator ¼ 106.54612.95), and (C) Day 46 (þpredator ¼ 88.97614.46; –predator ¼ 100.68612.63). Individuals were pooled across ponds within treatments on each sampling date. Variance was significantly greater in predator treatments compared to non-predator controls (LMM: v2 ¼ 5.7, df ¼ 1, P ¼ 0.017).
