The proliferation of invasive plants into native ecosystems is a major threat to biodiversity and ecosystem functioning on a global scale; a disturbance predicted to become more severe in the 21st century. To offset the adverse effects of invasive plants on ecosystem function and overall health, a fundamental understanding of the mechanisms by which plant invaders alter ecological communities and networks is essential. This research examined the effects of invasive plants on soil communities in urban woodlands. Here, I adopted a multidisciplinary framework, which included a combination of meta-analyses, field experimentation, and Next-Generation DNA sequencing to profile soil microbial communities. In short, my research findings show that invasive plants can severely alter the function and structure of woodland soil communities, with the effect being stronger for soil microflora (i.e. fungi) than higher trophic levels (i.e. predators).
