ABSTRACT: Several ecological key factors were indicated in the
Lake Kinneret ecosystem during 1969-2000:
Elevation of the biomass of non-pyrrhophyte-phytoplankton, chlorophyta,
cyanobacteria, and diatoms; decline of Peridinium maximal from 215 - 240 to 175 - 200 ranges (g/m2); decline of
zooplankton (herbivore and predator) relative to phytoplankton biomass (g/m2);
lower loads of Nitrogen and slightly also phosphorus in the river Jordan
discharge; decline of precipitations and lake water level; significant decline
of epilimnetic nitrogen and minor changes of phosphorus concentrations
initiated decline of N/P mass ratio to the establishment of a significant
change of the ecosystem to be modified from P to N limitation. What could be
other than essential outcome of future prediction that results of 20 years
(1969-2000) of routine and comprehensive monitor carried out in Lake Kinneret
initiated? The Lake Kinneret ecosystem dynamics after 2000 justified retroactive
post-factum earlier conclusion of appropriate predictability.
