Berdugo et al. show that increasing aridity promotes thresholds on the structure and functioning of drylands (see the Perspective by Hirota and Oliveira). Their database includes 20 variables summarizing multiple aspects and levels of ecological organization. They found evidence for a series of abrupt ecological events occurring sequentially in three phases, culminating with a shift to low-cover ecosystems that are nutrient- and species-poor at high aridity values. They estimate that more than 20% of land surface will cross at least one of the thresholds by 2100, which can potentially lead to widespread land degradation and desertification worldwide. </p> <p> Science , this issue p. 787 ; see also p. 739 </p [SDE] Environmental Sciences 0301 basic medicine 570 Increasing aridity [SDE.MCG]Environmental Sciences/Global Changes Climate Change availability Promotes sequential vegetation cover Systemic thresholds soil forest Soil 03 medical and health sciences https://purl.org/becyt/ford/1.6 XXXXXX - Unknown Climate change functional traits https://purl.org/becyt/ford/1 climate Climatical change Ecosystem Dryland ecosystems Aridity 2.
