FIG. 2 in Predators Induce Morphological Changes in Tadpoles of Hyla andersonii

FIG. 2. Representative photos of tadpoles of H. andersonii reared without predators (top) and with predators (bottom) and their corresponding ImageJ pixel color histograms. Lower values indicate darker pixels, and higher values indicate lighter pixels in the image. The y-axis of the histograms indicates the frequency of pixels for each darkness score.
