Distribution of Ciliophora, stramenopiles, fungi and Rhizaria among the 5 analyzed samples (oxic surface-0, -8 worms; anoxic subsurface-0, -8 worms and lugworm burrow) as obtained by 454 sequencing. Numbers within each class refer to phylotypes obtained after clustering sequences at 97% similarity threshold, without taking single singletons into account. Numbers in brackets display the number of sequences for each taxon, as obtained after application of the quality procedure (for details see ‘Materials and methods’ section) Ciliophora All samples Oxic Oxic Anoxic Anoxic Lugworm surface surface subsurface subsurface burrow 0 worms 8 worms 0 worms 8 worms Colpodea Bryometopus 1 (4) 1 (4) Litostomatea Paraspathidiidae 9 (156) 6 (22) 7 (134) Trachelotractus 4 (142) 4 (131) 1 (11) Epiphyllum 3 (34) 3 (33) 1 (1) Litonotus 1 (4) 1 (3) 1 (1) Nassophorea Zosterodasys 2 (16) 1 (13) 1 (2) 1 (1)
