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

人类有意或无意地将许多物种从它们的原产地引入到它们以前没有出现的地区。其中一些物种已经归化，其中一些已经成为入侵者。然而，只是在最近几年，这种生物入侵的全球范围模式和过程才开始出现。这是通过大规模的合作举措实现的，如由DFG和FWF资助的全球归化外来植物群（GloNAF）数据库。GloNAF数据库目前包括1388个地区的16，564种外来维管植物物种。在这个新的后续提案中，我们希望继续更新和扩展GloNAF。我们将使用该数据库来测试如何威胁的地位和共性在本地范围内涉及到其他地方的归化。这将通过将GloNAF与ThreatSearch数据库以及关于欧洲不同地区本地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倡议的重新调查植被相关数据，我们将评估欧洲植物群落中外来和本土植物物种丰富度和组成变化的小尺度模式和驱动因素。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的相互作用。最后，我们将使用物种分布模型对所有归化物种在GBIF中有足够的发生记录，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影响的了解。

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.
