DOIAbstract
Changes in soil biota following fire and its successive influence on their interactions with plants may have direct implications on the invasion successof woody alien species in fire-prone ecosystems. In this work, we experimentally addressed if soil biota from burned and unburned areas differentially affectgrowth and nutrition of two dominant woody natives (Lithraea molleoides and Vachellia caven) and three woody invaders (Gleditsia triacanthos, Ligustrumlucidum and Pyracantha angustifolia) that occur on fire-prone ecosystems of central Argentina. Our results indicate that growth and P content in tissuesof both woody natives Lithraea and Vachellia were generally benefited by arbuscular mycorrhizal fungi (AMF) and that these effects did not...
