Mapping and Modeling Land-Sea Nutrient Feedbacks to Enhance Island Ecosystem Resilience

沿海海景是动态过渡区，易受各种人为干扰的影响，这些干扰在陆地-海洋界面上起作用并相互作用。在陆地上的局部压力源（例如，土地使用变化、城市化）和海洋（例如，污染，过度捕捞）环境现在与全球压力源（例如，海洋变暖、酸化），从而极大地改变了海景的形式和功能，沿着改变了海景提供沿海社区所依赖的基本生态系统货物和服务的能力。虽然人类活动对沿海海景的影响已经在物种范围的变化和生物入侵，食物网重新布线和生物多样性丧失方面进行了评估，但关于人类活动对支撑沿海生态系统功能的复杂，多尺度陆海养分交换途径的后果的研究仍然很少。迫切需要开展阐明陆海养分动态时空尺度和模式的研究，以遏制生态系统健康、生物多样性和复原力的持续快速下降，特别是在缺乏离散边界的“开放”沿海海景中。

Coastal seascapes are dynamic transitional zones susceptible to various anthropogenic disturbances operating and interacting across the land-sea interface. Local stressors in both terrestrial (e.g., land-use change, urbanization) and marine (e.g., pollution, overfishing) environments now coalesce with global stressors (e.g., ocean warming, acidification) to dramatically alter the form and function of seascapes, along with their ability to provide essential ecosystem goods and services on which coastal communities rely. Although human impacts on coastal seascapes have been evaluated with respect to species range shifts and biological invasions, food web rewiring, and biodiversity loss, there remain few published studies on the consequences of anthropogenic activities on the complex, multi-scale land-sea nutrient exchange pathways that underpin coastal ecosystem functioning. Studies illuminating the spatiotemporal scales and patterns of land-sea nutrient dynamics are urgently required to curb ongoing, rapid declines in ecosystem health, biodiversity, and resilience, particularly in 'open' coastal seascapes lacking discrete boundaries.
