Invasive alien species (IAS) have negative as well as positive effects on human well-being. They can alter ecosystem properties, functions and associated ecosystem services (ES). However, many IAS have negative effects (resulting from reducing ES or by increasing or creating ecosystem disservices (EDS), the latter termed genuine negative effects) on, e.g. biodiversity, crop and timber production and/or human health. We present a novel framework, linking traits of IAS via ES and EDS to affected environmental and socioeconomic sectors. By applying the framework, we were able to identify whether a plant trait affects different sectors (positively and/or negatively) and whether the same trait impacts one but benefits another sector. Positive effects correspond to an increase in ES/a reduction in EDS whereas impact represents a reduction in ES/an increase in EDS. The framework is applicable across traits and species, including the direction (positive/negative) and strength of effects. Furthermore, we classified six socioeconomic and environmental sectors frequently affected (positively or negatively) by invasive plants, along with the list of ES and EDS relevant in these sectors. The framework can be used as a tool for assessing multiple ES and EDS and for prioritizing the management of affected sectors.

将入侵植物的特性与生态系统服务和损害联系起来

外来入侵物种(IAS)对人类福祉既有正面影响,也有正面影响。它们可以改变生态系统的特性,功能和相关的生态系统服务(ES)。但是,许多国际会计准则对例如生物多样性,作物和木材生产和/或人类健康产生负面影响(由于减少生态系统服务或增加或造成生态系统损害(EDS),后者被称为真正的负面影响)。我们提供了一个新颖的框架,将通过ES和EDS将IAS的特征链接到受影响的环境和社会经济部门。通过应用该框架,我们能够确定一种植物性状是否影响不同部门(正面和/或负面),以及同一性状是否影响一个部门但有益于另一部门。积极影响对应于ES的增加/ EDS的减少,而影响代表ES的减少/ EDS的增加。该框架适用于所有性状和物种,包括效应的方向(正/负)和强度。此外,我们对入侵性植物经常受到(正面或负面)影响的六个社会经济和环境部门进行了分类,并列出了与这些部门相关的ES和EDS清单。该框架可以用作评估多个ES和EDS以及确定受影响部门管理优先级的工具。以及与这些部门相关的ES和EDS列表。该框架可以用作评估多个ES和EDS以及确定受影响部门管理优先级的工具。以及与这些部门相关的ES和EDS列表。该框架可以用作评估多个ES和EDS以及确定受影响部门管理优先级的工具。
