abstract = {In alpine zones, soil microbial biomass and activity are
strongly dependent on the seasonal snow cover. Current
models assume that microbial biomass reaches an annual peak
in winter under the insulating snowpack with a subsequent
sharp decline during snowmelt. In this study, we
investigated the seasonal dynamics of the soil microbial
biomass in the Central Alps, where usually early snowfall
buffers winter soil temperatures. We conducted a large-scale
survey in three mountains around Davos (Switzerland) along
altitudinal gradients from approximately 1900 to 2800 m
above sea level. Using a space-for-time approach during
snowmelt, soil samples were taken (1) under, (2) at the edge
of, and (3) one meter away from remaining snow patches. One
additional sample per site was taken in summer to further
evaluate the seasonal dynamics. In total, 184 soil samples
from 46 different sites were analyzed. We measured microbial
biomass C and N, enzymatic activity and dissolved C and N.
We observed an increase of microbial biomass and dissolved C
during and immediately after snowmelt, as well as an
increase from spring to summer. We suggest that the absence
of soil freezing in winter and the growing amounts of
dissolved C supported a continued growth, without a sudden
collapse of the microbial biomass. Our results underline the
importance of the insulating effect of the seasonal snow
cover for the microbial dynamics. Global warming is
modifying the timing and abundance of the seasonal snow
cover, and our results will help to refine models for the
dynamics of soil microbes in alpine ecosystems.},
