                      could have immediate and carry-over effects on biological
                      processes in high-altitude forest soils, but the nature of
                      these processes remain poorly understood. We conducted a
                      snow-exclusion experiment to investigate the immediate and
                      cross-seasonal effects of increased soil frost on soil CO2
                      efflux and biological activity in a subalpine spruce forest
                      on the eastern Tibetan Plateau, China. The increased frost
                      reduced soil CO2 efflux by ∼15 and $∼19\%$ in the
                      winters of 2015/2016 and 2016/2017, respectively. Increased
                      frost also tended to decrease soil basal respiration, the
                      amount of microbial phospholipid fatty acids and the
                      activities of enzymes involved in soil carbon cycling during
                      the winters. Winter soil nitrogen availabilities were higher
                      in the snow-exclusion treatment than in the control plots.
                      However, these effects did not carry over to the following
                      growing season. Our results suggest that increased frost
                      reduces winter soil respiration by direct environmental
                      effects (e.g. soil temperature) and indirect biological
                      processes (e.g. microbial biomass and activity), whereas
                      increased frost did not induce any cross-seasonal effects.
                      These findings underscore the ecological importance of
                      seasonal snowpack and microbe-associated carbon processes in
                      subalpine forests where winter snowfall is decreasing
                      substantially.},
