The figure described interspecific and intraspecific variability in two co-existing stream fishes (Poecilia reticulata and Rivulus hartii). The fish are sampled from two types of communities: with predators (High Predation) and without predators (Low Predation). The figure show that interspecific differences in organismal stoichiometry vary significantly between streams, and are therefore sensitive to background environmental conditions. Differences between the predation communities are subtle, but interspecific differences in OS are slightly noisier in high predation compared to low predation communities.
