Report: Long-term studies of Macrozoobenthos in intertidal and shallow subtidal habitats Norderney (1986)
Description
» Near the East Frisian island of Norderney two sites
permanently investigated in order to study longterm fluctuations of Macrozoobenthos: one transect (since)
1977) at the northern side in shallow subtidal waters and another one (since 1976) at the sheltered southern side
in the intertidal area of the Wadden Sea. Since 1980 the investigations have been continued in the frame of COST—
47, sedimentary intertidal programs (including the shallow subtidal habitats colonised by the Macoma
Balthica community). The results up to 1984, respectively to 1985, are presented and the changes of abundance of
the dominant species are discussed. The influences of water temperatures and sediment disturbances caused by wave action. There is evidence
that the intertidal variety of the Macoma balthca
community shows a greater stability than the subtidal
variety.
