Though common in nature, the importance of plant-plant facilitation to coexistence and the maintenance of plant diversity at community scales is poorly understood. This project aims to advance understanding of how positive interactions (facilitation) impact on coexistence among plant species as well as local patterns of diversity. To achieve these aims the project will use a combination of field experiments and a comparative analysis of competition and facilitation in Australian, Californian and Spanish annual plant communities with a novel modelling approach for predicting coexistence across variable environments. Outcomes are expected to include an innovative predictive framework of use for plant conservation in Australia and beyond.

虽然在自然界中很常见，但植物-植物促进在群落尺度上共存和维持植物多样性的重要性却知之甚少。该项目旨在促进对植物物种之间的积极相互作用（促进）如何影响共存以及当地多样性模式的理解。为了实现这些目标，该项目将结合现场实验和对澳大利亚、加利福尼亚和西班牙一年生植物群落的竞争和促进进行比较分析，并采用一种新的建模方法来预测不同环境下的共存。预计结果将包括一个创新的预测框架，用于澳大利亚和其他地区的植物保护。
