Abstract
In this paper, we investigated the relationship between body size, phylogeny and spatial patterns of distribution in three aquatic frog genera (Nyctibatrachus, Micrixalus, Hylarana) that have undergone extensive diversification in the Western Ghats of India. We used a comprehensive sampling protocol designed to uncover fine-scale divergence between allopatric and parapatric lineages. The dataset comprises (a) distribution data for three aquatic genera at an assemblage level, which was used to carry out the community assembly analyses, and (b) the time-calibrated phylogenetic trees, body size, distribution and microhabitat data (trait_data), and species co-occurrence data required to reproduce the evolutionary analyses described in the manuscript.

Description of the data and file structure
The dataset comprises (a) distribution data for three aquatic genera at an assemblage level, which was used to carry out the community assembly analyses, and (b) the time-calibrated phylogenetic trees, body size, distribution, microhabitat data (trait_data), and species co-occurrence data required to reproduce the evolutionary analyses described in the manuscript.
Files and variables
File: WG_frog_bodysize_evolution_data.RData
Description: This file contains all the time-calibrated phylogenetic trees (nycti, micri, indo), body size, distribution and microhabitat data (trait_data), and species co-occurrence data (nycti_comm_data, micri_comm_data, indo_comm_data) for the three frog groups (Nyctibatrachus, Micrixalus, and Hylarana (Indosylvirana)) required to reproduce the analyses described in the manuscript.
File: WG_frog_bodysize_Hylarana_data.csv
Description: This file contains the data on cooccurring species for this genus across sites/assemblages.
Variables
- Genus: Genus to which the species belongs
- Site: Assemblage to which each species belongs; the name refers to the hill range (if there were multiple assemblages within a hill range, they are numbered accordingly)
- Lat: Latitude of the site
- Long: Longitude of the site
- Locality: Place name for each sampled site (assemblage)
- Species found in syntopy: Current scientific name (genus and species) of species found at the site
- Average SVL (mm): Snout-vent length (distance from the tip of the snout to the posterior edge of the cloaca)
- Size class: Size category as assigned by the cluster analysis
File: WG_frog_bodysize_Micrixalus_data.csv
Description: This file contains the data on cooccurring species for this genus across sites/assemblages.
Variables: Same as above
File: WG_frog_bodysize_Nyctibatrachus_data.csv
Description: This file contains the data on cooccurring species for this genus across sites/assemblages.
Variables: Same as above
Code/software
File: WG_frog_bodysize_community_analyses.R
Description: This script file contains analyses for comparing the body size distribution of local communities with null distributions of randomly assembled communities, and plots Figure 2.
File: WG_frog_bodysize_evolution_analyses.Rmd
Description: This R script performs body size clustering, phylogenetic community structure analyses, and body size evolution analyses for the three selected stream-dwelling frog clades described in the paper.
File: WG_frog_bodysize_evolution_simulations.Rmd
Description: This R script performs posterior predictive simulations to evaluate the statistical strength of the competition models (Matching Competition and Diversity-Dependent models) for small tree sizes. This script simulates trait data and phylogenetic trees with a specified number of taxa under different levels of competition and evaluates the fit of the competition models relative to Brownian motion, Ornstein-Uhlenbeck, and Early Burst models.
