Large variations of salinity and dissolved oxygen and their effects onmacrobenthic communities inLake Sihwa,
the west coast of Korea

S
ince the dyke construction the lake Sihwa has undergone unstable environments such as large fluctuation of salinity and oxygen
due to irregular exchanges of water between the outer saline zone and the inner brackish one, inflow of a good deal of pollutants
from non-point and point sources and water stagnancy. It indicates that the lake ecosystem has a variability of species composition
and species density. Especially, benthic organisms lack the ability to cope up with changes in the environment because most of them
are sedentary and have limited mobility, thus the variation gives rise to change in the community structure. The Sihwa macrobenthos
have responded to the severe environment, which was reported in some previous studies. However, these studies referred to the
succession of macro fauna for only three years of the initial stage after the dyke construction. In the present paper, I report on the
long-term responses of the macrobenthos to the large variation in salinity and dissolved oxygen for fifteen years after the birth of the
lake.
