title: Data from: A trait-based approach elucidates the synergies and vulnerabilities of ecosystem services in drylands, as well as their decoupling from biodiversity

description: Several studies have explored the linkages among biodiversity, ecosystem
 functions, and services; however, how biodiversity affects bundles of
 ecosystem services through collaboration and antagonism remains unknown,
 especially in ecologically fragile drylands. In this study,
 species-specific plant traits were extended to ecosystem services at the
 community level through transect sampling of shrublands in Northwest China
 using a trait-based approach.
 It revealed biodiversity-ecosystem service (ES)
 relationships in drylands and how environmental pressures (sites with high
 aridity, precipitation seasonality, and soil total salt) and human
 activities affect them. We found synergistic relationships among ESs at
 both the species and community levels, and environmental
 pressures and anthropogenic activities such as cotton cultivation
 and grazing are important drivers of ES decline at community
 level. However, environmental pressure did not reduce the alpha
 diversity such as species richness, Simpson, Shannon-Wiener,
 Margalef, and Pielou index of the shrublands, and the species richness of
 shrublands was decoupled from the ESs. Our findings highlight the
 vulnerability and sensitivity of drylands and show that rational human
 production activities are important for maintaining ESs in drylands.
