Raw dataset from Yang (2023) Ecosystem-level decoupling in response to reduced precipitation frequency and degradation in steppe grassland.xlsx

In this study, we assessed the effects of decreased precipitation frequency and grassland degradation on ecosystem coupling, quantified based on the mean strength of pairwise correlations among multispecies communities and their physicochemical environment, individual functions, and ecosystem multifunctionality, and reported their relationships within a mechanistic plant-nematode-microorganism-soil interactions framework. Ecosystem coupling, individual functions, multifunctionality and their relationships were analysed and calculated based on this dataset.
