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:

1. A zipped folder "videos", where raw videos used in the study are stored.
2. 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.
3. A README file with details on how the data and code is organized.
4. Supplementary Material file including all raw data used in the main data analysis (SupplementaryMaterial.xlsx)
5. 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)
6. 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.
7. 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.
