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: Scripus mariqueter and Spartina alterniflora. 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'

本研究旨在阐明种子萌发过程中的形态特征变化对次生水媒传播潜力及盐沼物种成功定植的影响机制。我们针对两种盐沼先锋物种——海三棱藨草（Scripus mariqueter）与互花米草（Spartina alterniflora），开展了两轮不同场景的水槽实验与一系列野外调查。本数据集包含论文中每张图表所使用的原始数据，具体组织形式如下：
1. 水槽实验数据
a. 种子形态特征
b. 表层种子的次生扩散起始时间
c. 沉积种子的次生扩散起始时间
2. 野外调查数据
a. 潮流条件
b. 床面高程变化
