Appendix A. A table and a figure describing the biological community of our study.
Table A1. Species used, their taxonomic affiliations, maximum size, relative size class, and dietary needs: B = bacterivore, O = omnivory on small flagellates and/or ciliates, S = scavenger of decaying organisms, P = photosynthetic, and R = direct resource utilization. (Data from personal observations, Peterson [1992] for protozoans, and Smith [2001] for rotifers.)
