Summary Snow overlays the majority of the G reenland I ce S heet ( GrIS ). However, there is very little information available on the microbiological assemblages that are associated with this vast and climate‐sensitive landscape. In this study, the structure and diversity of snow microbial assemblages from two regions of the western GrIS ice margin were investigated through the sequencing of small subunit ribosomal RNA genes....

Will warming lead to an increased use of older soil organic carbon ( SOC ) by microbial communities, thereby inducing C losses from C ‐rich alpine soils? We studied soil microbial community composition, activity, and substrate use after 3 and 4 years of soil warming (+4 °C, 2007–2010) at the alpine treeline in S witzerland. The warming experiment was nested in a free air CO 2 enrichment experiment using depleted 13 CO 2 (δ 13...
