TL;DR: Direct and indirect effects of temperature were the main drivers of the spatial distribution in the toxins produced by the cyanobacterial community, the toxin concentrations and toxin quota, and a Toxin Diversity Index (TDI) increased with latitude, while it decreased with water stability.

TL;DR: In this article, Verspagen, van Herk and van Wijk present a collection of essays with the same authors, including a discussion of the role of gender in the relationship between women and women's empowerment.

TL;DR: In this article, the origin of dissolved organic matter (DOM) in Lake Vortsjarv in Estonia was traced, and it was shown that the proportion of Al-DOM decreased with increasing water temperature, chlorophyll a, and pH and increased with an increasing water level and concentration of yellow substances and DIC.

TL;DR: It is shown, globally, that the frequency of plant species with this trait increases with bicarbonate concentration, and regionally, the frequency is reduced at sites where the CO2 concentration is substantially above the air equilibrium, consistent with this traits being an adaptation to carbon limitation.

TL;DR: In this paper, the dependence of macrophyte parameters (distribution depth, width of the reed belt, density and length of shoots) on a number of abiotic factors (wind patterns, nutrient loading, slope of the littoral, granulometric sediment composition) in a large, shallow, and eutrophic Lake Vortsjarv (270 km 2, average depth 2.8 m) in Estonia in 1997 was investigated.
