Interactions among invading species: transient hybridisation and rates of replacement

栖息地经常被多个物种相继入侵。这些入侵者之间的相互作用可能会改变它们的传播速度和最终分布。这个项目将结合实验研究和模型来测试特定的假设，当一个物种到达一个已经有近亲的地区并开始取代它时，发生的过程。它将使用两枚海上火箭(Cakile sp.)目前入侵澳大利亚海岸线是其重点。通过确定这种物种相互作用的重要性，这项研究将有助于更好地估计入侵物种的影响，从而改进对它们的管理决策。

Habitats are often invaded sequentially by multiple species. Interactions between these invaders can potentially alter their rates of spread and eventual distributions. This project will combine experimental research and modelling to test specific hypotheses about the processes occurring as one species arrives in a region already containing a close relative and proceeds to replace it. It will use two sea rockets (Cakile sp.) currently invading Australia’s coastline is its focus. By determining the importance of such species interactions, the research will contribute to the development of better estimates of invasive species impacts, thereby improving decisions on their management.
