ESM 1 the Fauna Inhabiting Burrows of S

ESM 1 The fauna inhabiting burrows of S. quoianum within marsh banks (M), wood (W), and sandstone (S). The invasion status is classified as native, non-native (a.k.a. introduced, non-indigenous, exotic, invasive), both (if the taxon includes both native and non-native species), or unknown. The trophic group includes mesograzers (Me, herbivores < 2.5 cm in length), detritivores (D), predators (P), suspension feeders (Su), and scavengers (Sc). The mobility group includes motile (Mo), sedentary (Sd, e.g. tube building epifauna), or sessile species (Se).

a. Assignment of the trophic and mobility group was based on congeneric species

b. Although cited as a facultative deposit feeder, we categorized M. balthica as a suspension feeder since it was not found inhabiting sediment

c. These organisms were found inhabiting burrows during initial surveys but were not found in samples
