"Climate-related changes of soil characteristics affect bacterial community composition and function of high altitude and latitude lakes". In a recent publication in Global Change Biology, Rofner et al. show that the origin of soil source (from above or below the treeline) is a major factor structuring bacterial community composition of oligotrophic lakes at high altitude and latitude.

Climate change affects lake catchment characteristics including soil runoff composition. In a recent publication in Global Change Biology, Rofner et al.  show that the origin of soil source (i.e., from above or below the treeline) is a major factor structuring bacterial community composition of oligotrophic lakes at high altitude and latitude regions.

Further, they show that changes in soil-derived organic matter can alleviate bacterial phosphorus-limitation and potentially have major effects on the carbon and phosphorus cycling in lakes. The study was done in lake Saanajärvi in Finland (a) and the alpine lake Gossenköllesee in Austria and was funded by a FWF project.
