Sessile community attached to invasive and native snail shells in the Swan River Estuary. a–c Taxonomic richness and density of solitary and modular sessile organisms found on shells in the Swan River Estuary in seagrass beds (black circles) versus sand-flats (grey circles). d Shell densities. e–f Total abundances of solitary and modular sessile organisms associated with dominant shell types in the middle and lower Swan River Estuary, shallower than 3 m. Different letters indicate a significant difference (p < 0.05) with error bars 95 % confidence limits (see online S2-3 for statistical results)
