Infauna shift trait-productivity relationships in submerged aquatic vegetation communities

This data and code (RStudio) are associated with the peer-reviewed research article, titled 'Root puppet masters: Infauna shift trait-productivity relationships in submerged aquatic vegetation communities'. The data is a product of a 15-week in situ transplant experiment in the northern Baltic Sea. It involved experimental submerged aquatic plant communities with, and without, experimental additions of Macoma balthica, a sedentary bivalve. Experimental plant communities were tricultures with varying species composition, compiled from a pool of 6 different species, to create an experimental gradient of trait community weighted means (CWMs) that allowed us to detect changes more clearly in plant trait-biomass production relationships in response to the M. balthica treatment. The plant species used in the experiment were Zostera marina, Potamogeton perfoliatus, Zannichellia major, Ruppia cirrhosa, Stuckenia pectinata and Myriophyllum spicatum., For a full description of data collection and processing, please see the Methods section in the article, 'Root puppet masters: Infauna shift trait-productivity relationships in submerged aquatic vegetation communities'. The text file is an accessible format of RStudio script, which explicitly shows how data was handled., , # Infauna shift trait-productivity relationships in submerged aquatic vegetation communities [https://doi.org/10.5061/dryad.6t1g1jx7g](https://doi.org/10.5061/dryad.6t1g1jx7g) ## Description of the data and file structure Data was collected during a 15-week transplant experiment conducted *in situ* in the northern Baltic Sea. Artificial triculture communities of submerged aquatic vegetation species were constructed (30 x 30 cm), using mixtures of 6 different plant species. Their species assemblage was designed to create a gradient in measureable plant functional trait values. The artificial plant communities were replicated, so that every artifical plant community came in pairs. One of the pairs was treated with an experimental addition of ten adult *Macoma balthica* additions and the other served as a control treatment. The *M. balthica* treatment was administered using a mark-recapture approach. At the end of the experiment, the experimental communities were harvested and measured ...本数据集与配套代码（基于RStudio）均与已通过同行评审的研究论文《根际操控者：底内动物改变沉水植物群落的性状-生产力关系》相关联。该数据集源自波罗的海北部开展的一项为期15周的原位移植实验。实验构建了添加与不添加实验用底内双壳类（Macoma balthica）的沉水植物实验群落。实验植物群落为三元混培群落，由6个物种的组合库中选取物种配置而成，通过调整物种组成构建了性状群落加权均值（community weighted means, CWM）的实验梯度，以便更清晰地检测植物性状-生物量生产关系对该双壳类添加处理的响应变化。本实验所用植物物种分别为：大叶藻（Zostera marina）、穿叶眼子菜（Potamogeton perfoliatus）、大角果藻（Zannichellia major）、卷叶川蔓藻（Ruppia cirrhosa）、篦齿眼子菜（Stuckenia pectinata）与穗状狐尾藻（Myriophyllum spicatum）。 有关数据收集与处理的完整说明，请参阅该研究论文的方法部分：《根际操控者：底内动物改变沉水植物群落的性状-生产力关系》。配套的文本文件为RStudio脚本的可访问格式，清晰展示了数据的处理流程。 # 底内动物改变沉水植物群落的性状-生产力关系 https://doi.org/10.5061/dryad.6t1g1jx7g ## 数据与文件结构说明 本数据集采集自波罗的海北部开展的一项为期15周的原位移植实验。研究人员构建了规格为30×30 cm的人工沉水植物三元混培群落，所用植物涵盖6个不同物种，并通过调整物种组成构建了可量化的植物功能性状值梯度。该人工植物群落设置重复组，每两个群落为一组配对：其中一组施加添加10只成熟Macoma balthica的实验处理，另一组作为对照组。Macoma balthica的添加处理采用标记-重捕法实施。实验结束后，对实验群落进行收获并开展测量……
