TL;DR: The presence and composition of DOM in the water proved important for both CYN degradation rates in preconditioned sediments and for the lag phase, and retention of CYN proved negligible under the investigated conditions.

TL;DR: This case emphasizes the need for further investigation of potentially toxic, non-bloom forming cyanobacteria in less eutrophic water bodies and underlines the novel challenge of developing appropriate surveillance schemes for respective bathing sites.

TL;DR: In 1993 12 eutrophic waterbodies and four laboratory strains were examined for their content of microcystins and toxicity was assessed with bioassays: primary rat hepatocytes for testing hepatotoxicity and a CHO-K1 cell line for determining more unspecific cytotoxicity.

TL;DR: In both lakes, maxima of the dissolved CYN fraction occurred later in the season than those of the particulate fraction, and it reached higher concentrations, indicating that CYN is poorly decomposed and accumulates in the water.

TL;DR: In this article, the authors review the current understanding of limitation through N and P and of co-limitation and conclude that Reynolds is still correct: (i) Liebig's law of the minimum holds and reducing P is sufficient, provided concentrations achieved are low enough; (ii) analyses of nutrient limitation need to exclude evidently non-limiting situations.
