Annual cycle of Planktothrix agardhii nature population.
Original language description
Changes in abundance, biovolume and morphology of Planktothrix agardhii in a natural population were followed over one year period in shallow fishpond Bílá Lhota (Central Moravia, Czech Republic). The selected environmental parameters (pH, oxygen, temperature, conductivity, nutrients, light) were measured at the surface and at the bottom of the fishpond, together with the Planktothrix abundances and filament morphology - filament length, width, shape, aerotopes (gas vacuoles) formation. The annual cycleof P. agardhii in this hypertrophic fishpond starts in March with the germination of hormogonia and the growth of overwintered filaments. The filament length quickly increases to a maximum length in April. The following summer period can be characterized by filament shortening and by changes in the aerotopes shape. On the other hand the abundance and biomass of P. agardhii is increasing until the maximum in August. Further shortening of filaments, loss of aerotopes and hormogoniae forma

Czech description
Roční cyklus planktonní sinice P. agardhii ve vztahu k ekologickým faktorům byl studován na modelové lokalitě, rybníku v arboretu Bílá Lhota. Je dokumentována morfologická variabilita a strategie přezimování této sinice, všeobecně rozšířené v mělkých stojatých vodách.
