TL;DR: Examination of stream and river systems across Europe highlights the large spatial variability in THg and MeHg concentrations at the European scale, and underscores the importance of DOM composition on mercury cycling in fluvial systems.

TL;DR: In this article, a 44-year time series of water temperature from nine depths in a small mountain lake was analyzed using dynamic linear models and temporal trend decomposition, and the results showed a significant autumn/winter warming effect of lake water together with an increasing intensity of temperature fluctuations in this seasonally ice-covered mountain lake.

TL;DR: Pesticide levels are generally monitored within agricultural areas, but are commonly not assessed at public places as mentioned in this paper, thus, the impact of environmental site characteristics on the number and concentration of pesticides was assessed.

TL;DR: The goal is to promote ways to understand the ecological function of alpine stream invertebrates and the potential effects of alteration of their trophic relationships by ongoing environmental changes like glacier retreat, water exploitation, or immigration of invasive species.

TL;DR: In exploring the occurrence of 59 taxa within the dipteran family Chironomidae in relation to key-environmental variables in alpine and sub-alpine streams, it was showed that sediment load, water temperature, periphyton density, and fine particulate organic matter mostly explain assemblage structures.
