abstract = {Winter snow cover is a major driver of soil microbial
processes in high-latitude and high-altitude ecosystems.
Warming-induced reduction in snow cover as predicted under
future climate scenarios may shift soil bacterial
communities with consequences for soil carbon and nutrient
cycling. The underlying mechanisms, however, remain elusive.
In the present study, we conducted a snow manipulation
experiment in a Tibetan spruce forest to explore the
immediate and intra-annual legacy effects of snow exclusion
on soil bacterial communities. We analyzed bacterial
diversity and community composition in the winter (i.e., the
deep snow season), in the transitional thawing period, and
in the middle of the growing season. Proteobacteria,
Acidobacteria, and Actinobacteria were dominant phyla across
the seasons and snow regimes. Bacterial diversity was
generally not particularly sensitive to the absence of snow
cover. However, snow exclusion positively affected Simpson
diversity in the winter but not in the thawing period and
the growing season. Bacterial diversity further tended to be
higher in winter than in the growing season. In the winter,
the taxonomic composition shifted in response to snow
exclusion, while composition did not differ between
exclusion and control plots in the thawing period and the
growing season. Soil bacterial communities strongly varied
across seasons, and the variations differed in specific
groups. Both soil climatic factors (i.e., temperature and
moisture) and soil biochemical variables partly accounted
for the seasonal dynamics of bacterial communities. Taken
together, our study indicates that soil bacterial
communities in Tibetan forests are rather resilient to
change in snow cover, at least at an intra-annual scale.},
