Cambios provocados en el suelo por la invasión de acacias australianas

摘要: Lorenzo, P., Rodriguez-Echeverria, S. 2015. Soil changes mediated by invasive Australian acacias. Ecosistemas 24(1): 59-66. Doi.: 10.7818/ECOS.2015.24-1.10 Invasive acacias can have a great impact on abiotic soil properties and the structure of microbial communities, altering processes services in invaded ecosystems. In general, cause significant increase litter, carbon nitrogen contents, alter biogeochemical cycles reduce water availability also modify functional genetic diversity bacterial fungal communities. Interestingly, there is co-invasion exotic N-fixing bacteria associated with invasion some These microsymbionts associate native legumes, therefore disrupting legume-rhizobia symbiosis. All these biotic due to be detrimental for plant species, decreasing their growth or impairing performance. addition, boost because they positive effect germination, competitive ability plant-soil feedbacks are maintained over time jeopardize natural recovery
