Structure and function of restored and natural salt marshes: Implications for ecosystem resilience and adaptive potential

Salt marshes have ecological and economic value, but shoreline development, the increasing rate of sea-level rise, and other human impacts have caused significant loss of salt marshes. As a result, restoration of these ecosystems is widespread. For restoration and management to be effective, it is imperative to improve our understanding of marsh-building plants that serve as the ecological foundation of these habitats. Given the observed differences in characteristics between populations of smooth cordgrass, Spartina alterniflora, restoration plantings may impact the biodiversity and resilience of restored ecosystems. Understanding differences in the structural and functional outcomes of active planting of restoration sites will enable the long-term success of restoration efforts to be improved. Natural and restored salt marshes in Long Island Sound were studied in 2021–2022 for S. alterniflora genetics, biomass, stem morphology, and faunal community composition. The average genotypic d..., Please see publication for full methodology: \"Structure and function of restored and natural salt marshes: implications for ecosystem resilience and adaptive potential\" (Estuaries and Coasts)., , # Data from: Structure and function of restored and natural salt marshes: Implications for ecosystem resilience and adaptive potential [https://doi.org/10.5061/dryad.rjdfn2zmd](https://doi.org/10.5061/dryad.rjdfn2zmd) These data were collected in 2021-2022 field research in 12 salt marsh sites (plus 1 common garden site) in Connecticut, USA. The full methods and results can be found in a publication in the journal \"Estuaries and Coasts\" (Crosby et al. 2024). ## Description of the data and file structure All raw data have been aggregated into individual csv files corresponding to different datasets and/or data types. The included data are: (1) Spartina alterniflora plant metrics (density, height, diameter, flowers), (2) water quality data from the field sites, (3) details about the common garden planting experiment, (4) S. alterniflora plant metrics from the transplanted plants in the common garden (density, height, diameter, flowers), (5) S. alterniflora biomass (above and belowgr...盐沼（salt marshes）兼具生态与经济价值，但岸线开发、海平面上升速率加快以及其他人类活动干扰已导致盐沼出现大规模丧失。因此，此类滨海生态系统的修复工作已在全球广泛开展。为确保修复与管理工作取得实效，亟需深化对作为这类栖息地生态基础的造沼植物的认知。鉴于互花米草（Spartina alterniflora）不同种群间存在性状差异，修复种植活动可能会对修复后生态系统的生物多样性与恢复力产生影响。明晰修复场地主动种植所带来的结构与功能响应差异，有助于提升修复工程的长期成效。 2021–2022年，研究团队对长岛湾（Long Island Sound）的天然与修复盐沼开展了调查，针对互花米草（S. alterniflora）的遗传学特征、生物量、茎秆形态以及动物群落组成进行了分析。平均基因型数据……完整研究方法详见论文"Structure and function of restored and natural salt marshes: implications for ecosystem resilience and adaptive potential"（发表于期刊Estuaries and Coasts），数据集来源：https://doi.org/10.5061/dryad.rjdfn2zmd 本数据集采集自2021–2022年美国康涅狄格州12个盐沼点位（外加1个同质种植园（common garden）点位）的野外调查工作。完整方法与结果可参阅期刊Estuaries and Coasts刊载的论文（Crosby et al. 2024）。 ## 数据与文件结构说明 所有原始数据已整合为对应不同数据集与数据类型的独立CSV文件。本次公开的数据包括：(1) 互花米草植株性状指标（密度、株高、茎径、开花状况）；(2) 野外点位的水质监测数据；(3) 同质种植园种植实验的详细信息；(4) 同质种植园内移栽互花米草的植株性状指标（密度、株高、茎径、开花状况）；(5) 互花米草生物量（地上与地下……）
