      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.

      In this study, we applied a step-wise modeling procedure to test the relative effects of taxonomic diversity, functional identity, and functional diversity on macrophytes community productivity along water depth gradient. Macrophyte community productivity was strongly determined by functional trait composition within community, but not significantly affected by taxonomic diversity. Our results suggested both mechanisms of mass ratio and niche complementarity can operate simultaneously on variations in community productivity, and considering both CWM and FD would lead to a more profound understanding of traits–productivity relationships.
