The interplay between facilitation and habitat type drives spatial vegetation patterns in global drylands
International audience The spatial configuration of vascular vegetation has been linked to variations in land degradation and ecosystem functioning in drylands. However, most studies on spatial patterns conducted to date have focused on a single or a few study sites within a particular region, speci...

International audience The spatial configuration of vascular vegetation has been linked to variations in land degradation and ecosystem functioning in drylands.
