Dataset for "Plant traits determining biogeomorphic landscape dynamics: a study on clonal expansion strategies driving cliff formation at marsh edges"

This dataset contains i) the clonal expansion traits of three marsh species (<i>Spartina anglica</i>, <i>Scirpus maritimus</i>, and <i>Phragmites australis</i>) at marsh edges in a series of mesocosm experiments; and ii) cliff formation at mimicked marsh edges (<i>S. anglica</i> and <i>S. maritimus</i>, that with contrasting clonal expansion traits) in a flume experiment. This study examined how species-specific differences in expansion strategy, i.e. clonal step-length of laterally expanding tillers, both respond to sediment type and drive cliff formation and persistence.

本数据集包含两部分实验数据：
i) 一系列中宇宙实验（mesocosm experiments）中，3种盐沼物种——大米草（*Spartina anglica*）、藨草（*Scirpus maritimus*）与芦苇（*Phragmites australis*）——在盐沼边缘的克隆扩张性状（clonal expansion traits）；
ii) 流水槽实验（flume experiment）中，模拟盐沼边缘的陡坎形成过程，受试物种为克隆扩张性状存在显著差异的大米草（*S. anglica*）与藨草（*S. maritimus*）。
本研究探讨了物种特异性扩张策略的差异——即横向扩张分株的克隆步距（clonal step-length）——如何同时响应沉积物类型，并驱动陡坎的形成与持续存在。
