The Evolution of Functionally Redundant Species; Evidence from Beetles
Fig 2
Size distributions of diving beetles in the different zoogeographical regions indicated in the central panel (e) and for the Northern (b) and Southern hemisphere (h) combined.
The solid curve represents a kernel smoothed estimator of species density (see methods). Dashed curves represent the fitted constituent distributions computed by means of latent class analysis as in Fig 1. See S2 File for mode analysis.
