Abstract

Advances in ecological research during the last decades have led to an improved understanding of the impacts of alien species. Despite that, the effects of alien macrofungi have often received little attention and are still poorly understood. With the aim of reducing this knowledge gap, we compiled a database of the recorded socio-economic and environmental impacts of alien macrofungi. This database was compiled from all relevant sources we could identify, through an exhaustive literature review, considering the identity of known alien taxa and explicit indications of impacts of any kind. In total, 1440 records of both negative and positive impacts were collected for 374 distinct species in different regions of all continents, except Antarctica. The most frequently recorded impacts are related to the mutualistic interactions that these fungi can form with their host plants. In total 47.8% of all records refer to the indirect negative effect of these interactions, by facilitating the colonization of invasive plants, while 38.5% refer to their positive contribution to the growth of forestry species. Less frequently recorded negative impacts included ectomycorrhizal interactions with native plants, plant pathogenicity and human poisoning after ingestion. Additional positive impacts include the use as a food source by native species and human populations and commercial exploitation. Alien macrofungi are an increasingly prevalent component of human-dominated ecosystems, having a diverse array of negative and positive impacts on native biota and human population. Our database provided a first step towards the quantification and mapping of these impacts.
外来大型真菌的负面和正面影响:一个全球范围的数据库
在过去的几十年里,生态学研究的进展使人们对外来物种的影响有了更好的了解。尽管如此,外来大型真菌的影响通常很少受到关注,人们对其了解也很少。为了缩小这种知识差距,我们编制了一个记录在案的外来大型真菌的社会经济和环境影响的数据库。该数据库是根据我们可以通过详尽的文献综述确定的所有相关来源编制的,考虑到已知外来分类群的身份和任何类型影响的明确迹象。除南极洲外,各大洲不同地区共收集了374个不同物种的1440份负面和正面影响记录。最频繁记录的影响与这些真菌与其宿主植物形成的互惠相互作用有关。总的来说,47.8%的记录提到了这些相互作用的间接负面影响,通过促进入侵植物的定植,而38.5%的记录提到它们对林业物种生长的积极贡献。较少记录的负面影响包括外生菌根与本地植物的相互作用、植物致病性和摄入后的人类中毒。其他积极影响包括本地物种和人口将其用作食物来源以及商业开发。外来大型真菌是人类主导的生态系统中越来越普遍的组成部分,对本地生物群和人类种群产生了各种各样的负面和积极影响。我们的数据库为量化和绘制这些影响的地图迈出了第一步。
