Effects of plant traits and ecosystem properties on wave attenuation and soil carbon content

Understanding the relationships among the environment, species traits and ecosystem properties is important for developing management measures that optimize the delivery of ecosystem services (ESs). Here, we identify the most important relationships responsible for the delivery of two key ESs provided by tidal marshes: (1) nature-based shoreline protection through wave attenuation and (2) mitigation of climate change through soil carbon storage. In two tidal zones below and above the mean high water (MHW, Elbe Estuary, Germany) level, we measured environmental parameters, such as soil salinity and inundation, as well as plant traits representing adaptations to hydrodynamic stress and strongly influencing decomposition rates.
Multiple linear regression results showed that wave attenuation rates were positively related to aboveground community biomass and stem bending resistance, and soil organic carbon was positively related to stem-specific density (below the MHW level). In the tidal zo..., , Microsoft Excel

明晰环境、物种性状与生态系统属性之间的内在关联，可为制定优化生态系统服务（ecosystem services, ESs）供给的管理策略提供科学支撑。本研究聚焦潮汐湿地提供的两项关键生态系统服务，明确了支撑其供给的核心关联：其一为通过波能衰减实现的自然型岸线防护，其二为依托土壤碳封存缓解气候变化。
我们在德国易北河口平均高潮位（mean high water, MHW）上下的两个潮汐带中，测定了土壤盐度、潮汐淹没等环境参数，以及表征植物对水动力胁迫适应性且显著影响分解速率的植物性状。
多元线性回归分析结果显示，波能衰减速率与地上群落生物量及茎秆抗弯折性呈显著正相关；土壤有机碳含量则与平均高潮位以下区域的茎秆比密度呈显著正相关。在潮汐[原文内容未完整呈现]，Microsoft Excel
