  1. Globally, momentum to restore damaged habitats has been increasing. For example, the number of European shellfish restoration projects has quadrupled in the past 3 years. In line with the increasing focus on both restoration and climate change mitigation efforts, this study highlights how these two practices can complement each other.
  2. This experimental study quantifies the active and passive sediment deposition associated with the European flat oyster (Ostrea edulis) and the organic and inorganic carbon fractions of the deposits. Treatments included ‘dead’, ‘live’, and control to account for (i) passive deposition, (ii) biodeposition and passive deposition, and (iii) background deposition respectively. By utilizing these data, the expected carbon deposition associated with a restored flat oyster bed was investigated.
  3. The experiment was conducted ex situ, with natural seawater input. Covariate data on temperature, suspended particulate influx, salinity, and oxygen availability were recorded. Enhanced sedimentation (2.9 times) and organic carbon deposition (three times) were observed in the presence of living oysters, compared with the control. The shell structure of the oysters had no influence on passive sedimentation in this study.
  4. By developing a full understanding of the ecosystem services (functioning, supporting, regulating, and cultural) provided by a habitat, it becomes possible to quantify overall ecosystem function. This evidence is key in advising policymakers, restoration funders, and marine spatial planners on the connection between keystone species restoration, ecosystem service restoration, and conservation management.
  5. The enhancement of benthopelagic coupling by the European flat oyster, evidenced here for the first time, is contextualized from the perspective of quantification of ecosystem service provision for both restoration practices and blue carbon store management. The data produced in this study are discussed comparatively with work that has focused on other species from both Europe and the USA.

遗漏了全部内容:欧洲扁平牡蛎可食牡蛎的碳沉积率的初步估计

  1. 在全球范围内,恢复受损生境的势头一直在增加。例如,在过去三年中,欧洲贝类恢复项目的数量增加了三倍。随着人们对恢复和减缓气候变化工作的关注日益增加,本研究着重介绍了这两种做法如何相辅相成。
  2. 这项实验研究量化了与欧洲牡蛎(Osrea edulis)以及沉积物中有机碳和无机碳组分相关的主动和被动沉积物沉积。处理包括“死”,“活”和控制,以分别考虑(i)被动沉积,(ii)生物沉积和被动沉积以及(iii)背景沉积。通过利用这些数据,研究了与恢复的平坦牡蛎床相关的预期碳沉积。
  3. 该实验是在天然条件下进行的,使用了天然海水。记录有关温度,悬浮颗粒涌入,盐度和氧气可用性的协变量数据。与对照组相比,在有活生蚝的情况下观察到沉淀作用增强(2.9倍)和有机碳沉积(3倍)。本研究中牡蛎的壳结构对被动沉积没有影响。
  4. 通过全面了解栖息地提供的生态系统服务(功能,支持,调节和文化),可以量化整个生态系统的功能。该证据对于为决策者,恢复资助​​者和海洋空间规划者提供咨询,帮助他们了解关键物种恢复,生态系统服务恢复和保护管理之间的联系。
  5. 这是欧洲扁牡蛎增强底栖鱼类耦合作用的首次证明,是从为恢复实践和蓝碳储存管理提供生态系统服务的量化角度出发的。这项研究产生的数据与针对欧洲和美国其他物种的研究进行了比较讨论。
