摘要

全球贸易、旅游业和人口流动的迅速发展增加了外来植物进入新地区的数量。在这里,我们评估了植物特性和气候适宜性在南部非洲1407种栽培外来植物归化成功中的作用。我们使用以气候适宜性为中介的中介分析来量化植物特征对归化成功的直接和间接影响,包括系统发育亲缘性、种子质量、株高、原生来源、原生范围大小和生长形式。结果表明,归化物种比非归化物种具有更高的气候适宜性。此外,种子质量、植株高度、短生草本生长形式和原生范围大小与归化成功呈正相关。相比之下,系统发育亲缘性和欧洲本土血统与入籍成功呈负相关。这些关联是由气候适宜性间接介导的,在所有情况下间接效应占总效应的30%以上。我们的研究强调了考虑气候适宜性对全面了解植物特征如何影响外来植物归化成功的重要性。补充资料:在线版本包含补充资料,下载地址:10.1007/s10530-025-03677-3。

Indirect role of climatic suitability in mediating the effects of plant characteristics on naturalization success of cultivated alien plants in Southern Africa.

The rapid expansion of global trade, tourism, and human mobility has increased the introduction of alien plants into new regions. Here, we assessed the role of plant characteristics and climatic suitability in the naturalization success of 1,407 cultivated alien plants in Southern Africa. We used mediation analysis with climate suitability as a mediator to quantify the direct and indirect effects of plant characteristics, including phylogenetic relatedness, seed mass, plant height, native origins, native range size, and growth forms on naturalization success. We found that naturalized species have higher climatic suitability compared to non-naturalized ones. Additionally, seed mass, plant height, short-lived herbaceous growth form, and native range size are positively associated with naturalization success. In contrast, phylogenetic relatedness and a native origin in Europe were negatively associated with naturalization success. These associations were indirectly mediated by climatic suitability, with indirect effects accounting for more than 30% of the total effect in all cases. Our study underscores the significance of considering the role of climatic suitability for a comprehensive understanding of how plant characteristics impact the naturalization success of alien plants.

期刊介绍: Biological Invasions publishes research and synthesis papers on patterns and processes of biological invasions in terrestrial, freshwater, and marine (including brackish) ecosystems. Also of interest are scholarly papers on management and policy issues as they relate to conservation programs and the global amelioration or control of invasions. The journal will consider proposals for special issues resulting from conferences or workshops on invasions.There are no page charges to publish in this journal.
