The structure of plant spatial association networks is linked to plant diversity in global drylands.

1. Despite commonly used to unveil the complex structure of interactions within ecological communities and their value to assess their resilience against external disturbances, network analyses have seldom been applied in plant communities. We evaluated how plant-plant spatial association networks vary in global drylands, and assessed whether network structure was related to plant diversity in these ecosystems.

[The Construction of a Mental Health Component for the National Survey: NMHS 2015, Colombia].
