Aims Dryland biotic communities (plants and biocrusts) are known to maintain multiple functions (multifunctionality) and services (multiservices) that decline with overgrazing by domestic livestock. Here, we evaluate the role of biotic communities in controlling the responses of multiple functions and services to grazing in an arid shrubland.
