Two potential equilibrium states in long-term soil respiration activity of dry grasslands are maintained by local topographic features.

ABSTRACT: Soil respiration of grasslands is spatio-temporally variable reflecting the changing biological activities of the soil. In our study we analysed how the long-term soil respiration activities of dry grasslands would perform in terms of resistance and resilience. We also investigated how terrain features are responsible for response stability. We conducted a 7-year-long spatial study in a Hungarian dry grassland, measuring soil respiration (R_s), soil temperature (T_s) and soil water content (SWC) along 15 measuring campaigns in 80 × 60 m grids and soil organic carbon content in 6 of the occasions. Two proxy variables were introduced to grasp the overall R_s activity, as well as its temporal stability: average rankR_s, the temporal average R_s
