Sexual dimorphism in subterranean amphipod crustaceans covaries with subterranean habitat type: data and R code

The data and R code used for data analyses in the manuscript titled "Sexual dimorphism in Niphargus amphipods is predicted by surface-subterranean environmental gradient". The collection contains: A zipped folder "videos", where raw videos used in the study are stored. A zipped folder "tracking_results", where video-tracking results obtained from the raw videos are stored, along with supporting files and R code (Rscript_extract_behavior.Rmd) with custom functions (Behavior_custom_functions.Rmd) needed to analyze tracking results and retrieve final behavioral data. A README file with details on how the data and code is organized. Supplementary Material file including all raw data used in the main data analysis (SupplementaryMaterial.xlsx) A supporting file with data from another study used in the main data analysis (sex_ratio.xlsx, results from https://onlinelibrary.wiley.com/doi/full/10.1111/jeb.13917; https://zenodo.org/records/5175861) Two files containing phylogenetic trees: one complete phylogenetic tree of Niphargus (consensus_tree) and 100 randomly drawn phylogenetic trees from the stationary phase of the Bayesian analysis, pruned to focal species (100_pruned_trees), which were used in the main data analysis. The Rcode containing the code of the main data analysis to reproduce the reported results (RScript_data_analysis.Rmd), as well as some additional analyses not included in the manuscript.本数据集包含题为《泥钩虾属（Niphargus）端足类的性二态性由地表-地下环境梯度预测》的手稿中数据分析所用的数据与R代码。本数据集具体内容如下： 1. 名为“videos”的压缩文件夹，存储本研究使用的原始视频素材。 2. 名为“tracking_results”的压缩文件夹，存储从原始视频中提取的视频追踪结果，同时包含配套文件、用于分析追踪结果并获取最终行为数据的自定义函数文件（Behavior_custom_functions.Rmd）及对应R脚本（Rscript_extract_behavior.Rmd）。 3. 一份README文件，详细说明数据集与代码的组织架构。 4. 补充材料文件（SupplementaryMaterial.xlsx），包含主数据分析所用的全部原始数据。 5. 辅助数据文件（sex_ratio.xlsx），包含本研究主分析中引用的另一项研究的数据，该研究结果来自https://onlinelibrary.wiley.com/doi/full/10.1111/jeb.13917 与 https://zenodo.org/records/5175861。 6. 两份系统发育树文件：其一为泥钩虾属的完整系统发育树（consensus_tree）；其二为从贝叶斯分析平稳期随机抽取的100棵系统发育树（经修剪以适配目标物种，命名为100_pruned_trees），二者均用于本研究的主数据分析。 7. R脚本文件（RScript_data_analysis.Rmd），包含可复现论文报告结果的主数据分析代码，以及部分未纳入手稿的额外分析代码。
