Annual variation of phytoplankton communities and environment factors were studied by investigation in the 20 sections(30°~32°N,121°27′~122°30′E)near the Deepwater Channel in the Yangtze estuary.
This paper deals with the species composition,abundance distribution,diversity index,the relationships with the concentration of nutrients and phytoplankton of zooplankton in Nanji MPA.
The effects of an organic compound, quickening-supporting curative(QS) on growth of Penaeus monodon, the phytoplankton fluctuations in QS experimental box, growth of Chlorella sp. and phosphorus utilization of Chlorella by monospecific culture in laboratory were investigated under different QS concentrations.
The given paper intends to report the authors' survey on the phytoplankton of Guanting Reservoir which has been done during the period of 2004—2005.In doing so,we have done some testing and measurements on the microcystins mass concentration and its change during the three months,that is,in June,July and August,2005,by using enzyme-linked immunosorbnent assay in hoping to investigate the correlation of microcystins mass concentration with the cell density of microcystis aeruginosa.
The main results from the simulations together with discussion about phytoplankton dynamics and primary production in Jiaozhou Bay are presented in the next paper (part II).
The effects of an organic compound, quickening-supporting curative(QS) on growth of Penaeus monodon, the phytoplankton fluctuations in QS experimental box, growth of Chlorella sp. and phosphorus utilization of Chlorella by monospecific culture in laboratory were investigated under different QS concentrations. Alkaline phosphatase activities(ALPA) of Chlorella and medium were determined, and effecting mechanisms by QS were discussed in the paper. Results showed that, mean weight and length increasing rates o...
Wavelet Analysis is a new technique which developing quickly in time-frequency analysis.Because of its characteristics of multiple timescales,multiple layers and multiple resolutions,wavelet analysis has been applied widely in signal analysis,information analysis and earth sciences,etc.In this paper,wavelet technique was used to analyze phytoplankton variation for the first time on the basis of two 30-day in situ observations which carried out in spring and autumn 2002,at the fish-farming area of Dapang'Ao ...
This paper deals with the species composition,abundance distribution,diversity index,the relationships with the concentration of nutrients and phytoplankton of zooplankton in Nanji MPA.98 species were identified including two ecological patterns named warm temperate species and warm water species.The dominant species of warm temperate species are Calanus sinicus、Pseudeuphausia sinicas、Muggiaea atlantica、Sagitta bedoti、S.nagae,and so on.That of warm water species includes S.enflata、Euchaeta concinna,etc.The ...
