John L. Maron, Auteur ; John Klironomos, Auteur ; Lauren Waller, Auteur ; Ragan M. Callaway, AuteurA prominent hypothesis for plant invasions is escape from the inhibitory effects of soil biota. Although the strength of these inhibitory effects, measured as soil feedbacks, has been assessed between natives and exotics in non-native ranges, fe[...]
