Biological invasions have major economic and environmental impacts on agriculture, epidemiology and conservation, yet our current understanding of the processes involved is hampered by studying causal drivers in isolation and largely ignoring rapid evolution. Here, we aim to use experimental populations of microbes, combined with a related theoretical and modeling agenda, to study: 1) the effect of independent, and combined, manipulation of disturbance and diversity on invasion success; and 2) the role of pre-adaptation to disturbance regimes in mediating invasion resistance. This integrated theoretical-empirical approach will greatly improve our conceptual understanding of the role disturbance and diversity play in mediating invasion.

生物入侵对农业，流行病学和保护产生了重大的经济和环境影响，但是我们目前对所涉及过程的理解受到了孤立研究因果驱动因素的影响，并且在很大程度上忽略了快速进化。在这里，我们旨在使用微生物的实验人群，并结合相关的理论和建模议程，以研究：1）独立和合并的操纵和多样性对入侵成功的影响； 2）预先适应对干扰制度的作用在介导侵袭性中的作用。这种综合的理论经验方法将大大提高我们对介导入侵中的作用和多样性的概念理解。
