Diversity in the deep sea

Supporting data for the paper: Mindel, B.L., Neat, F.C., Trueman, C.T., Webb, T.J. &amp; Blanchard, J.L. (2016) Functional, size and taxonomic diversity of fish along a depth gradient in the deep sea. PeerJ, 4:e2387; DOI 10.7717/peerj.2387<br><br>Datasets have been summarised to enable replication of figures and analyses from this paper. Data are provided by Marine Scotland Science from their ongoing deepwater trawl survey. <br><br>Calculate size diversity:<br>Input needed in order to calculate size diversity for each station using the Leinster-Cobbold measure of diversity. 'Class number' and 'Class midpoint' are based on length of individuals. 'Proportional abundance' is the proportion of biomass (based on the previous column 'Kg per hr') that that class accounts for within the station. The method of calculating size diversity (final column) can be found in the main manuscript.<br><br>Diversity and trait values:<br>Data needed to produce Figures 4, 5 and 6 from the paper. Includes values of all measures of diversity examined, plus means and standard deviations of continuous morphological traits as described in the manuscript.<br><br>Guild biomass: <br>Data needed to produce Figure 7 from the paper. Percentage of biomass accounted for in each depth band by each feeding guild.<br><br>Species codes: <br>Translation of species codes to Latin names.<br><br>Species site matrix:<br>One input into the calculation of functional diversity - biomass of each species in each station. The column names are species codes, and their translation to Latin names can be found in 'Species codes'.<br><br><br>

本数据集为以下论文的配套数据：Mindel, B.L.、Neat, F.C.、Trueman, C.T.、Webb, T.J. 与 Blanchard, J.L.（2016）发表于《PeerJ》的《深海沿深度梯度分布鱼类的功能多样性、体型多样性与分类多样性》，卷4，文章编号e2387；DOI：10.7717/peerj.2387

本数据集已完成汇总处理，可用于复现该论文中的图表与分析流程。数据由苏格兰海洋科学协会（Marine Scotland Science）基于其持续开展的深水拖网调查项目提供。

体型多样性计算：用于基于莱因斯特-科博尔德（Leinster-Cobbold）多样性测度，计算各采样站位的体型多样性。所需输入参数如下：'类别编号'与'类别中点值'基于个体体长确定；'比例丰度'为该类别在站位内的生物量占比（生物量参考前一列'千克每小时'计算）。体型多样性的计算方法（最终列）详见论文正文。

多样性与性状值：用于复现论文中图4、图5与图6的数据集。包含论文中所考察的全部多样性测度值，以及连续形态性状的均值与标准差，具体说明详见论文正文。

功能群生物量：用于复现论文中图7的数据集。包含各摄食功能群在各深度区间内的生物量占比。

物种代码对照表：用于将物种代码转换为拉丁学名。

物种-站位矩阵：用于功能多样性计算的输入数据之一，包含各物种在各站位的生物量。列名为物种代码，其对应的拉丁学名可参见'物种代码对照表'模块。
