Data presented in the publication: ‘The onset of secondary seed dispersal is controlled by germination-features: A neglected process in sudden saltmarsh establishment’

The objectives of this study were to elucidate how changes in seed morphological characteristics during germination affect the potential of secondary hydrophily transport and the successful establishment of saltmarsh species. We conducted two rounds of flume experiments with different scenarios and a series of field investigations, focus on two pioneer saltmarsh species: <i>Scripus mariqueter</i> and <i>Spartina alterniflora</i>. These files include the data used to create each figure in the manuscript, organized as follows: 1. Flume study a. Seed characteristics b. Secondary dispersal onset of superficial seeds c. Secondary dispersal onset of sedimentary seeds 2. Field investigation a. Tidal current conditions b. Bed elevation changes c. Water level d. Monthly temperature For a complete description, see 'Data description.docx'

本研究旨在阐明萌发阶段种子形态特征的变化，如何影响次生亲水传播潜力，以及盐沼物种的成功定植。我们开展了两轮不同场景的水槽实验与一系列野外调查，聚焦两种先锋盐沼物种：海三棱藨草（Scripus mariqueter）与互花米草（Spartina alterniflora）。本数据集包含论文中所有图表对应的原始数据，整理结构如下：1. 水槽实验数据 a. 种子特征 b. 表层种子的次生扩散起始情况 c. 沉积种子的次生扩散起始情况 2. 野外调查数据 a. 潮流条件 b. 底床高程变化 c. 水位 d. 月均温度。完整的数据说明请参阅"Data description.docx"
