TL;DR: It is suggested that CYN may be an important cyanobacterial toxin in German water bodies and that further data are needed to assess this, and analyses of phytoplankton data suggest Aphanizomenon sp.

TL;DR: It is hypothesized that reduced external nutrient loading leads to an intermediate recovery state with clear spring and turbid summer conditions similar to the pattern described for eutrophication, whereas internal lake restoration measures often resulted in clear-water conditions in spring and summer with returns to turbid conditions after some years.

TL;DR: Potential mechanisms that may have resulted in a positive effect of plants on transparency such as P uptake and immobilization by the dominant rootless macrophyte species Nitellopsis obtusa and Ceratophyllum demersum and other macrophytes-related mechanisms such as increased zooplankton grazing and allelopathy are discussed.

TL;DR: A one-dimensional, vertically resolved macrophyte model was developed based on PCLake and coupled to SALMO-1D and GOTM hydrophysics and validated against field data and suggests significant effects of submerged macrophytes on deep lake water quality.

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.
