  1. Coastal ecosystems provide important services to human population, such as nurseries for fish, carbon storage and coastal protection. However, the pressure faced by these systems due to global changes will strongly challenge the capacity of coastal ecosystems to persist. Therefore, it is crucial to understand the resilience of coastal ecosystems.
  2. Here, I propose that combining a resilience framework based on ecosystem properties with the functional trait response–effect framework would allow researchers and managers to quantify the resilience of coastal ecosystems. I place emphasis on salt marsh and sand dunes because of the higher availability of studies for these systems.
  3. First, I introduce the resilience framework based on ecosystem properties and, second, I show how adopting a functional trait perspective in this framework would allow researchers to link how environmental changes influence ecosystem properties. In turn, measuring the changes in ecosystem properties would allow researchers to measure the resilience of the system.
  4. Synthesis. I reviewed several types of disturbances (e.g. storms and sea-level rise) that are threatening the persistence of coastal ecosystems, with an emphasis on salt marshes and sand dunes. Applying this resilience framework reveals, for instance, that the same suite of traits (e.g. plant density and stiffness) increase marsh resistance to multiple threats (e.g. storms and sea-level rise); yet, these traits vary along environmental gradients (e.g. along estuaries) and, therefore, the resilience of marshes vary accordingly. Overall, this framework would allow researchers to gather crucial insights on the resilience of coastal ecosystems and to set reference marks for measuring their resilience under environmental changes.

沿海生态系统的恢复力:基于功能特征的观点

  1. 沿海生态系统为人类提供重要服务,例如鱼类苗圃、碳储存和沿海保护。然而,这些系统因全球变化而面临的压力将强烈挑战沿海生态系统的持续能力。因此,了解沿海生态系统的恢复能力至关重要。
  2. 在这里,我建议将基于生态系统特性的弹性框架与功能性状响应-效应框架相结合,将使研究人员和管理人员能够量化沿海生态系统的弹性。我将重点放在盐沼和沙丘上,因为对这些系统的研究具有更高的可用性。
  3. 首先,我介绍了基于生态系统特性的弹性框架,其次,我展示了如何在该框架中采用功能特征的观点,使研究人员能够将环境变化如何影响生态系统特性联系起来。反过来,测量生态系统特性的变化将使研究人员能够测量系统的弹性。
  4. 合成。我回顾了威胁沿海生态系统持久性的几种干扰类型(例如风暴和海平面上升),重点是盐沼和沙丘。例如,应用该复原力框架表明,同一组特征(例如植物密度和刚度)可提高沼泽对多种威胁(例如风暴和海平面上升)的抵抗力;然而,这些特征随环境梯度(例如沿河口)而变化,因此,沼泽的恢复力也相应地变化。总体而言,该框架将使研究人员能够收集有关沿海生态系统恢复力的重要见解,并为衡量其在环境变化下的恢复力设置参考标记。
