Benthic (streambed) biofilms metabolize a substantial fraction of particulate organic matter and nutrient inputs to streams. These microbial communities comprise a significant proportion of overall biomass in headwater streams, and they present a primary c ...
Scaling aquatic ecosystem processes like nutrient removal is critical for assessing the importance of streams and rivers to watershed nutrient export. We used pulse NH4+ enrichment experiments and measured net NH4+ uptake in 7 streams throughout a mountain ...
Lakes are an inherent component of the global carbon cycle. They receive dissolved organic matter (DOM) from the catchment, which is stored, transformed and respired, or delivered downstream. In this study, we show that a subalpine lake shifts its role fro ...

Stream ecosystem metabolism integrates production and respiration of organic matter and plays a fundamental role in the global carbon (C) cycle. Several studies have identified distal and proximal physical controls, for example, land use and transient s ...
Boreal and alpine streams are highly sensitive to climate change. Previous studies have shown the relevance of streams for carbon cycling in boreal landscapes. Less work has been done on alpine streams, and we do not understand the contributions from these ...
Local climates in the Northern and Southern Hemisphere are influenced by Arctic Amplification and by interactions of the Antarctic ozone hole with climate change, respectively. Polar changes may affect hydroclimatic conditions in temperate regions, for exa ...
Adsorption onto solid water interfaces is a key process governing the fate and transport of waterborne viruses. Although negatively charged viruses are known to extensively adsorb onto positively charged adsorbent surfaces, virus adsorption in such systems ...
Tropical reef-building corals live in symbiosis with a wide range of micro-organisms, including unicellular Symbiodinium dinoflagellates also called zooxanthellae. These photosynthetic endosymbionts live inside the coral gastroderm cells. Although corals c ...
Universalmultifractal (UM) analysiswas used to investigate the scaling properties of snowfall at high temporal and spatial resolutions. Snowfall datawere recorded using a 2Dvideo disdrometer (2DVD) in the SwissAlps. Six 1-h-long periods of snowfall, half i ...
Studying biological processes on the level of live cells with the help of biocompatible reac-tions has tremendously advanced our understanding of basic biology. However, the great complexity of many human pathologies such as cancer, diabetes and neurodegen ...
