The key aim of NichePac is to improve our understanding of the mechanisms driving niche dynamics and spread of alien plants. We will use the Pacific region as a model system as it hosts exceptionally high numbers of alien plants, many of which have also naturalized in other parts of the world. In the project, we will (i) quantify observed niche shifts between native ranges and invaded mainland vs. invaded island systems, (ii) assess the naturalization potential of alien plants in the Pacific region as well as the predictors explaining their establishment success, and (iii) predict spatiotemporal spread dynamics and spatiotemporal hotspots of potential plant invasions. Overall, this will allow an improved predictive capacity of potential future naturalization and spread of alien species, contributing to the scientific basis of conservation and management of invasive species.

NichePac的主要目的是提高我们对驱动外来植物生态位动态和传播的机制的理解。我们将把太平洋地区作为一个模式系统，因为那里有非常多的外来植物，其中许多也已经在世界其他地方归化。在这个项目中，我们将(I)量化观察到的原生范围和入侵大陆与入侵岛屿系统之间的生态位变化，(Ii)评估太平洋地区外来植物的归化潜力以及解释它们建立成功的预测因素，以及(Iii)预测潜在植物入侵的时空传播动态和时空热点。总体而言，这将提高对外来物种未来可能归化和传播的预测能力，有助于为外来物种的养护和管理提供科学依据。
