Correlation analysis between physical environmental factors and abundance of benthic and pelagic diatom assemblages in both the surface sediment and the water column was performed on these data. Correlations between benthic diatom assemblages in the sediment BDSed and in the water column BDWC and depth and salinity were not significant Table 3. All gut contents showed a higher ratio of benthic diatoms than that of pelagic species.
Acta Ecologica Sinica, 26 Abstract: Advances in ecological studies on estuarine zooplankton are reviewed on the domestic and abroad published papers.
This paper includes estuarine zooplankton species compositionspatial and temporal distributionbiomass and the reviews of the effects of the environmental factors. Estuaries are tidally-influenced ecological systems.
Fluctuations of environmental factors are more significant and complex in the systems due to the combination of fresh water and salt waterland and ocean influences. As a resultthe study of the spatial and temporal variability of estuarine zooplankton communities is very important for a better understanding of the functioning of coastal ecosystems.
Estuaries comprise extreme environments for zooplankton development. Typicallythe most abundant groups of zooplankton are protozoansrotiferscopepodsmysids and medusas. Environmental parameters and anthropogenic impacts play major roles in determining spatial and temporal patterns of zooplankton distribution and species composition.
Variability is mainly caused by foodtemperaturesalinityherbivory and riverflow. The fluctuation in salinity is tightly correlated with distribution of zooplankton. The influx of freshwater into the estuary has a dramatic impact on the community structure.
The microzooplankton -protozoansrotifers and copepod nauplii -plays a significant role in estuarine ecosystem. Microzooplankton represents a key link in the microbial food web and the traditional food web. Any attempt to determine the relative abundance of zooplankton groupsmust be based on collections obtained using a plankton net with an appropriate mesh size.
This was lead to serious underestimates of the smaller components of the zooplankton e. Additionally some ideas for further studies on estuarine zooplankton in China are proposed.
