Description:
Because we found previously that Chlamydomonas reinhardtii produces allelochemicals to which the rotifer Brachionus calyciflorus is sensitive, we explored its effects on other freshwater plankton. We used Chlamydomona s under light-, nitrogen- and phosphorus-limitation to test its allelopathic effect on Microcystis aeruginosa , Cryptomonas ozolinii , Ochromonas danica , Tetrahymena thermophila and Paramecium aurelia . Allelopathy depended strongly on the target organism. Only Cryptomonas suffered a marked negative effect. Among the resource limiting regimes, light limitation exerted the greatest effect.
