Environmental harshness mediates the quality of periphyton and chironomid body mass in alpine streams
Our results indicate that harsh environmental conditions, such as low temperatures and high turbidity, lead to lower taxon numbers and food quality and that food quality influences invertebrate occurrence and body mass in alpine and subalpine headwater streams. Closely related species respond differently to specific environmental conditions and may perform differing functions. This result widens our general understanding of climatechange effects on alpine streamecosystems and provides additional explanations for species abilities and performance.

The interplay between total mercury, methylmercury and dissolved organic matter in fluvial systems: A latitudinal study across Europe
Stream total-Hg and MeHg concentrations across European latitudinal gradient are highly variable. Soil derived organic matter inputs control total-Hg in European streams. Autochthonous organic matter controls MeHg formation in European streams

When the going gets tough, the tough get going: The enigma of survival strategies in harsh glacial stream environments
Here we show that Diamesinae - in contrast to Orthocladiinae - (both subfamilies of Chironomidae) have extremely flexible feeding strategies that explain their abundance, high body-mass, and predominance in glacier-fed streams.
