Zb. Tokarskaya et al., PHYTOPLANKTON IN THE COOLING POND OF A NUCLEAR-FUEL PLANT .1. SPECTRAL-ANALYSIS, Russian journal of ecology, 26(4), 1995, pp. 263-267
Dynamics of average monthly indices for 3 classes of phytoplankton and
for 24 hydrochemical, 7 meteorological, and 3 radiative factors were
investigated over a period of 26 years in the cooling pond of the Maya
k Production Association in Kyzyl-Tash Lake. The parameters were stati
stically treated by procedures of time series analysis. A seasonal suc
cession of examined features is described. It is established that deve
lopment of the diatoms peaks in February, and that of the green and th
e blue-green algae peaks in June and August, respectively. Seasonal gr
owth of the blue-green algae is substantially influenced by water temp
erature, Mn2+, O-2, CO2, and solar radiation; that of the green algae
is effected by water temperature, solar radiation, CO2, Mn2+, and clou
diness; that of the diatoms is controlled by SiO32-, Mn2+, K+ + Na+, C
O2, and water temperature.
