The development of novel communities has become an inevitable outcome of global change. Despite this, we have a poor understanding of the mechanisms driving their assembly. Here, experimental and modelling approaches will be used to identify how competition among native and exotic plant species change across key environmental gradients, leading to: resilient native communities; stable novel communities - mixes of native and exotic species; or, degraded communities dominated by exotic species. The annual plant communities of Western Australia's (WA) York Gum woodlands will be used as a model system. Outcomes will improve management of WA wildflower communities and provide a framework for predicting novel community formation worldwide.

小说社区的发展是全球变化的必然结果。尽管如此，我们对驱动其组装的机制了解甚少。在这里，实验和建模方法将被用来确定本地和外来植物物种之间的竞争如何在关键的环境梯度变化，导致：弹性本地社区;稳定的新社区-本地和外来物种的混合;或，退化的社区占主导地位的外来物种。西澳大利亚（WA）的约克树胶林地的一年生植物群落将被用作一个模型系统。研究结果将改善西澳野花群落的管理，并为预测全球新群落的形成提供一个框架。
