Wetlands are unique, highly biodiverse ecosystems of high conservation value that provide multiple ecosystem services to human society. However, the dynamic nature of wetlands creates abundant opportunities for the establishment and spread of invasive species, especially those well adapted to the current global prevalence of environmental change. Wetland invasibility is influenced by ongoing changes in climate and human land use (e.g., hydrologic modifications and eutrophication). Invasive species, in turn, can change the community composition and structure of the colonized wetlands through direct competition, predation, habitat alterations, hybridization, and pathogen transmission. Invaders can also alter ecosystem functioning, including hydrology, sedimentation, fire regimes, food webs, nutrient cycling, and succession. These changes in the biotic community and ecosystem functioning can affect human derived wetland services such as navigation, water distribution, and resource provision, as well as exaggerate problems related to human health. Although we currently possess diverse tools for managing individual species invasions, the current rate of global change may require creative approaches to achieve management success in the near future. Single-species or single-parameter approaches are unlikely to provide sustained biodiversity protection in this time of unprecedented environmental change, and hierarchical or multi-stressor approaches may become the new norm for managing wetland invasion.

湿地入侵:全球快速变化时期的多方面挑战

湿地是独特的、高度生物多样性的生态系统,具有很高的保护价值,可为人类社会提供多种生态系统服务。然而,湿地的动态特性为入侵物种的建立和传播创造了大量机会,尤其是那些很好地适应了当前全球普遍存在的环境变化的物种。湿地的侵袭性受到气候和人类土地利用(例如,水文变化和富营养化)的持续变化的影响。反过来,入侵物种可以通过直接竞争、捕食、栖息地改变、杂交和病原体传播来改变殖民湿地的群落组成和结构。入侵者还可以改变生态系统的功能,包括水文、沉积、火势、食物网、养分循环和演替。生物群落和生态系统功能的这些变化会影响人类衍生的湿地服务,例如导航、配水和资源供应,以及夸大与人类健康相关的问题。尽管我们目前拥有管理单个物种入侵的多种工具,但当前全球变化的速度可能需要创造性的方法来在不久的将来实现管理成功。在这个前所未有的环境变化时期,单一物种或单一参数的方法不太可能提供持续的生物多样性保护,分级或多压力源方法可能成为管理湿地入侵的新规范。以及夸大与人类健康有关的问题。尽管我们目前拥有管理单个物种入侵的多种工具,但当前全球变化的速度可能需要创造性的方法来在不久的将来实现管理成功。在这个前所未有的环境变化时期,单一物种或单一参数的方法不太可能提供持续的生物多样性保护,分级或多压力源方法可能成为管理湿地入侵的新规范。以及夸大与人类健康有关的问题。尽管我们目前拥有管理单个物种入侵的多种工具,但当前全球变化的速度可能需要创造性的方法来在不久的将来实现管理成功。在这个前所未有的环境变化时期,单一物种或单一参数的方法不太可能提供持续的生物多样性保护,分级或多压力源方法可能成为管理湿地入侵的新规范。
