Spartina anglica (hereafter Spartina) is an invasive perennial marsh grass shifting hydrodynamic regime and sediment characteristics in invaded area, thereby reducing macrobenthic diversity. There have been only a few studies focusing on the patch structure of according to size its effects macrofauna. A field experiment was conducted identify patches where they introduced no later than 5 years ...

A polychaete-assisted sand filter (PASF) can aid water recirculation systems for shrimp culture ponds by removing large amounts of nutrients and suspended solids chemically treating wastewater. By ingesting degrading organic matter, Perinereis helleri polychaetes reared in a PASF accumulate potentially remove infectious hypodermal hematopoietic necrosis virus (IHHNV) present wastewater from rea...

The ability of the common brackish water polychaete worm Nereis diversicolor O. F. Miiller to regulate osmotically and ionically has been well established (Schlieper, 1929; Beadle, 1937; Smith, 1955; Hohendorf, 1963; Oglesby, 1970; and others). Jergensen & Dales (1957) demonstrated an uptake of chloride against the concentration gradient at low salinities, with a maximum rate of exchange under ...
