摘要: The phytoplankton community structure of a hypertrophic lake was quantitatively determined with the aid flow cytometry. cytometry signals were calibrated to obtain cell-specific information, such as chl content and biovolume per cell. reliability this method tested laboratory cultures. results in respect distribution different algal groups obtained by compared from HPLC pigment fingerprinting. Both methods yield percentage contribution total a. specific absorption coefficient (a* Phy ) via visible (VIS) spectroscopy samples taken (Auensee) 2003. indicated that a* cell suspension is dependent on well environmental factors. linear relationship between at 675 nm product offered possibility normalize spectra acquire taxon-specific . estimated (675 nm) values used single wavelength 400 750 for representatives major groups. Our measurements show whole varies within season. Finally, we calculate light each group lake.
