在全球变化的背景下，全球沿海生态系统正受到入侵植物的威胁。然而，入侵植物如何影响本地动物群落，以及在全球沿海生态系统中入侵者清除/控制后本地动物群落是否可以恢复，仍然知之甚少。在这里，我们提出了第一个全球性的Meta分析，以量化米草属物种入侵对沿海动物群落的影响，并进一步评估米草属物种清除对动物群落恢复的结果，基于74项独立研究。我们发现入侵的米草属物种普遍降低了生物多样性（例如，物种丰富度），但沿海动物丰富度增加（例如，个体数）和适合度（例如，生物量），但对丰度的影响是微不足道的。的影响模式是强烈依赖于栖息地类型，动物类群，营养水平，和喂养类型。具体而言，米草物种入侵泥滩造成的影响比入侵植被生境。昆虫和鸟类在较高的营养水平受到入侵米草的强烈影响，表明入侵植物的影响可以级联向上沿着食物链。此外，米草入侵对食草动物和食肉动物等食物专家的影响更为明显。此外，我们的分析表明，入侵者的清除总体上有利于本地动物群落从米草入侵造成的流离失所中恢复过来，但这种恢复过程取决于具体的清除措施和时间。例如，长期的水涝对动物群的恢复产生了强烈的负面影响，因此不应鼓励。我们的研究结果表明，入侵植物可能会对本地动物群落的功能反应产生相反的影响。虽然入侵植物的清除可以恢复本地动物群落，入侵生态系统的未来功能重建应考虑到入侵物种对本地社区的遗留影响。这些研究结果为未来在全球变化加剧的情况下科学控制入侵物种和恢复生态系统提供了有意义的启示。
Coastal ecosystems worldwide are being threatened by invasive plants in the context of global changes. However, how invasive plants influence native faunal communities and whether native faunal communities can recover following the invader removals/controls across global coastal ecosystems are still poorly understood. Here, we present the first global meta‐analysis to quantify the impacts of Spartina species invasions on coastal faunal communities and further to evaluate the outcomes of Spartina species removals on faunal community recovery based on 74 independent studies. We found that invasive Spartina species generally decreased the biodiversity (e.g., species richness), but increased coastal faunal abundance (e.g., individual number) and fitness (e.g., biomass), though the effect on abundance was insignificant. The pattern of influence was strongly dependent on habitat types, faunal taxa, trophic levels, and feeding types. Specifically, Spartina species invasion of mudflats caused greater impacts than invasion of vegetated habitats. Insects and birds at higher trophic levels were strongly affected by invasive Spartina, indicating that invasive plant effects can cascade upward along the food chain. Additionally, impacts of Spartina invasions were more obvious on food specialists such as herbivores and carnivores. Furthermore, our analyses revealed that invader removals were overall beneficial for native faunal communities to recover from the displacement caused by Spartina invasions, but this recovery process depended on specific removal measure and time. For example, the long‐term waterlogging had strong negative impacts on faunal recovery, so it should not be encouraged. Our findings suggest that invasive plants could have contrasting effects on functional responses of native faunal communities. Although invasive plant removals could restore native faunal communities, future functional restorations of invaded ecosystems should take the legacy effects of invasive species on native communities into account. These findings provide insightful implications for future scientific controls of invasive species and ecosystem restoration under intensifying global changes.
