TL;DR: In this paper, the authors found a hierarchical structure in the community assemblage using distinct scales of lake clustering (number of k-means groups) based on species composition similarity (Hellinger distance).

TL;DR: In this article, the main sources of chemical variability in mountain lakes, defining a chemical classification of lakes, and developing tools to extrapolate their results to regional lake populations through an empirical regionalisation or upscaling of chemical properties.

TL;DR: In this article, the authors surveyed the distribution of trace elements in contemporary and pre-industrial sediment s in 275 lakes in alpine and arctic lake districts across Europe including the Pyrenees, Alps, the Rila Mountains, Retezat, Julian Alps, Tatras, Scottish mountains, Central Norway and Greenland.

TL;DR: In this paper, a static critical loads model, the First-order Acidity Balance (FAB) model, was used to assess (1) the extent of critical load exceedance in 300 lakes in nine European lake districts and (2) the relative importance of sulphur and nitrogen deposition in contributing to acidification.

TL;DR: Multivariate analysis (RDA) revealed that the nutrient concentrations in the lakes were significantly influenced by the soil percentage coverage of the catchment area and a nutrient decrease accompanied by an increase in size of zooplankton organisms in the period 1995-2001 led to a considerable increase of water transparency in the Lakes.
