Short summary

In mountain grasslands drought has distinct transient effects on soil nitrogen cycling and bacterial and archaeal ammonia-oxidizers (AOB and AOA), which could have been related to a niche differentiation of these two groups at increasing NH4+ levels. However, the effective strength of drought was modulated by the level of grassland management.
