Plant-Soil Feedback Effects on Germination and Growth of Native and Non-Native Species Common across Southern California

摘要: Changes in plant assemblages can influence biotic and abiotic soil conditions. These changes cause plant–soil feedbacks that inhibit or facilitate germination growth. Here, we contribute to a growing literature examining the endangered sage scrub ecosystem by growth of Artemisia californica, dominant native shrub species ecosystem, conditioned two widespread invaders (Brassica nigra, Bromus madritensis ssp. rubens), these invasive conspecific heterospecific soils. Our findings suggest that: (i) A. californica soils limit establishment some (B. nigra) but not others madritensis), (ii) conditions reduce all species, (iii) non-natives are negatively impacted microbes, contexts do better soil. As our were often incongruent with other studies examined interactions among similar at sites, infancy understanding complex interactions, developing predictive framework for involves how various respond different within ecosystem.
