Variations of parasitic groups along the water column. (a) Taxonomic alpha diversity (TDAlpha) and phylogenetic alpha diversity (PDAlpha) of each layer; blue boxes represent Oligohymenophorea, yellow ones represent Colpodea. (b) The number of ASVs and sequences of Oligohymenophorea and Colpodea. The frequence of occurrence indicates the ratio between the stations at which the taxa were detected and the total number of stations. (c) Dispersal ability of the main ciliate groups. (d) Taxonomic composition of Colpodea at the order level. (e) Taxonomic composition of Oligohymenophorea at the order level
