“…In spite of differences in species assemblages and different invasion histories (10–30 years), S. alterniflora was a major organic carbon source for all benthic macrofauna within a short time following the invasion in all three sampling regions. Similar results have been reported for marshes in Yangtze River estuary where both crabs and detritus‐feeding snails consume a large proportion of S. alterniflora detritus (Qin et al., ; Wang, Chu, Huang, Li, & Wu, ). The fast‐growing S. alterniflora exhibited high productivity and a well‐developed underground root system (Li et al., ), which could inhibit the import and availability of allothogenic food sources by reducing tidal flow and producing more detritus (Neira, Grosholz, Levin, & Blake, ; Neira, Levin, & Grosholz, ; Neira, Levin, Grosholz, & Mendoza, ).…”
