Appendix B. Visual representation of the nestedness analysis.
Fig. B1. Illustration of the nestedness analysis of plant communities along the stream-size gradient (catchment area). Directions of the arrows represent decreasing stream size (horizontal arrow), decreasing species incidence respectively (vertical arrow). Plant communities were found to be significantly nested along the stream-size gradient increasing downwards in the river network (see main text).
