Short summary
Amphistegina lobifera (Foraminifera) has colonized the Mediterranean through the Suez Canal, often forming thick sediments altering the invaded environments. Little is known about postmortem fate of its shells, so I investigated their turnover in the rhizosphere of the dominant Mediterranean seagrass. Most were bioeroded, likely by cyanobacteria and algae but not fungi occurring in the seagrass roots. Bioerosion may counterbalance accumulation of A. lobifera shells in the seabed substrate.
