Advancing the understanding of global plant invasions: building the bridge from data to drivers and biodiversity changes

人类故意和无意地将许多物种从他们的原生地区引入到以前没有出现过的地区。这些物种中的一些已经归化，一些已经成为入侵物种。然而，仅在最近几年，这种生物入侵的全球范围模式和过程才开始出现。这是通过全球归化外来植物群数据库等大规模合作举措得以实现的，该数据库由全球归化外来植物群数据库和全球归化外来植物群数据库资助。GloNAF数据库目前包括1388个地区的16,564种外来维管植物物种的条目。在这份新的后续提案中，我们希望继续更新和扩展GloNAF。我们将使用数据库来测试本地范围内的威胁状态和共性如何与其他地方的归化相关。这将通过将GloNAF与ThreatSearch数据库以及关于欧洲不同地区本土物种分布变化的多个数据集相结合来实现。此外，通过使用最近建立的ResurveyEurope倡议的重新调查的植被释放数据，我们将评估欧洲植物群落中外来和本地植物物种丰富度和组成变化的小规模模式和驱动因素。利用新的全球外来病原真菌数据库，我们将分析植物入侵和外来病原真菌之间的相互作用。最后，我们将使用物种分布模型对所有在GBIF中有足够出现记录的归化物种进行量化，以量化归化债务和外来物种的潜在全球范围。这些研究将进一步促进我们对当地和全球植物入侵及其对生物多样性的影响的理解。

Humans have deliberately and undeliberately introduced many species from their native regions into regions where they did not previously occur. Some of these species have become naturalized, and some of those have become invasive. However, only in the last couple of years, the global extent patterns and processes of such biological invasions have started to emerge. This has been possible through large-scale collaborative initiatives such as the Global Naturalized Alien Flora (GloNAF) database, funded by the DFG and FWF. The GloNAF database currently includes entries of 16,564 alien vascular plant species in 1388 regions. In this new follow-up proposal, we want to continue updating and expanding GloNAF. We will use the database to test how threat status and commonness in the native range relate to naturalization elsewhere. This will be done by combining GloNAF with the ThreatSearch database and with multiple datasets on changes in distributions of native species in different parts of Europe. Furthermore, by using resurveyed vegetation relevé data from the recently established ResurveyEurope initiative, we will assess small scale patterns and drivers of changes in alien and native plant species richness and composition in plant communities of Europe. By using the novel Global Alien Pathogenic Fungi database, we will analyze the interactions of plant invasions and alien pathogenic fungi. Finally, we will use species distribution modelling on all naturalized species with sufficient occurrence records in GBIF to quantify naturalization debts and the potential global ranges of alien species. These studies will further advance our understanding of local and global plant invasions and their impacts on biodiversity.
