Impact of nitrogen availability and soil communities on biomass accumulation of an invasive species

---

Abstract.
Exotic plant species impact belowground processes by influencing resource availability through enhanced
microbial activity as a consequence of litter inputs.We have little understanding of the impact of microbe-driven nutrient fluctuations on the biomass accumulation of invasive species. Here we attempt to answer the question on whether soil community-driven nitrogen availability influences invader biomass.We discovered that soil communities cultured by Ageratina adenophora, a neotropical invader in Asia, retain available nitrogen that influences the biomass of the invader. Through soil manipulation experiments we found that A. adenophora grows better in soil with a higher available nitrogen content. Ageratina adenophora-invaded soil had higher microbial activity and available nitrogen due to higher inputs of terpene-rich litter compared with soil not yet invaded by it. Our results provide evidence that microbe-linked nitrogen availability exerts a positive impact on A. adenophora biomass accumulation. Our workemphasizes the importance of soil community-driven nitrogen availability in invasion success.

Keywords: Ageratina adenophora; available nitrogen; exotic plant invasion; soil communities.
