Abstract

Abstract. Global climate change may enable invasive plant species (IPS) to invade protected areas (PAs), but plant invasion on a global scale has not yet been explicitly addressed. Here, we mapped the potential invasion pathways for IPS in PAs across the globe and explored potential factors determining the pathways of plant invasion under climate change. We used species distribution modelling to estimate the suitable habitats of 386 IPS and applied a corridor analysis to compute the potential pathways of IPS in PAs under climate change. Subsequently, we analysed the potential factors affecting the pathways in PAs. According to our results, the main potential pathways of IPS in PAs are in Europe, eastern Australia, New Zealand, southern Africa, and eastern regions of South America and are strongly influenced by changes in temperature and precipitation. Protected areas can play an important role in preventing and controlling the spread of IPS under climate change. This is due to the fact that measures are taken to monitor climate change in detail, to provide effective management near or inside PAs, and to control the introduction of IPS with a high capacity for natural dispersal. A review of conservation policies in PAs is urgently needed.
气候变化下保护区植物入侵路径建模:对入侵管理的启示
摘要全球气候变化可能使入侵植物物种(IPS)入侵保护区(PAs),但全球范围内的植物入侵尚未得到明确解决。在此基础上,我们绘制了全球植物入侵路径,并探讨了气候变化下植物入侵路径的潜在影响因素。利用物种分布模型估计了386种IPS的适宜生境,并利用廊道分析计算了气候变化下PAs中IPS的潜在路径。随后,我们分析了影响PAs通路的潜在因素。根据我们的研究结果,IPS在PAs中的主要潜在途径是在欧洲、澳大利亚东部、新西兰、非洲南部和南美洲东部地区,并且受温度和降水变化的强烈影响。在气候变化的背景下,保护区可以在预防和控制IPS的传播方面发挥重要作用。这是由于采取了详细监测气候变化的措施,在保护区附近或内部提供有效的管理,并控制引进具有高自然扩散能力的IPS。迫切需要对保护区的保护政策进行审查。

期刊介绍: Web Ecology (WE) is an open-access journal issued by the European Ecological Federation (EEF) representing the ecological societies within Europe and associated members. Its special value is to serve as a publication forum for national ecological societies that do not maintain their own society journal. Web Ecology publishes papers from all fields of ecology without any geographic restriction. It is a forum to communicate results of experimental, theoretical, and descriptive studies of general interest to an international audience. Original contributions, short communications, and reviews on ecological research on all kinds of organisms and ecosystems are welcome as well as papers that express emerging ideas and concepts with a sound scientific background.
