The stress response of net phytoplankton biomass size structure in Liaodong Bay
Based on net collection of phytoplankton samples in Liaodong Bay in all four seasons during 2012~2014, the distribution pattern of size structure of phytoplankton and its response to environmental stress were analyzed in the northern and southern areas of the bay. The stability of the phytoplankton community was estimated and was found to be dominated by small species in spring, summer and autumn, and by medium-sized species in winter. Phytoplankton biomass was controlled by medium-sized species in spring, summer and autumn, and by large species in winter. In general, phytoplankton sizes in the southern area were greater than those in the northern area. Large phytoplankton species were much more adaptive to oligotrophic water and a colder environment. The phytoplankton community in spring, autumn and winter was relatively stable; however, it deviated from equilibrium in summer. Phytoplankton community stability in the southern area was slightly better than in the northern area. TheW statistical value of the group of large species can be used as an evaluation index of phytoplankton community stability.
