Figure 4.

(a) The abundance of taxa in general taxonomic classes. The assignment to one of the classes is based on the phylogenetic analysis obtained in Arb (see Electronic Appendix). Gas, Gastrotricha; Tur, Turbellaria; Tar, Tardigrada; Ins, Insecta without chironomids; Ost, Ostracoda; Ano, Anomopoda; Aca, Acari; Rot, Rotifera; Har, Harpacticoida; Cyc, Cyclopoda; Chi, Chironomida; Pro, Protozoa; Nem, Nematoda. (b) Reoccurrence of taxa in different lakes. The dark grey parts refer to the fraction of sequences that were found in more than one lake in each taxon class. The numbers refer to the actual numbers.
