Diversifying in the mountains: spatio-temporal diversification of frogs in the Western Ghats biodiversity hotspot

Mountain ranges are hotspots of biodiversity. However, the mechanisms that generate biodiversity patterns in different mountainous regions and taxa are not apparent. The Western Ghats (WG) escarpment in India is a globally recognised biodiversity hotspot with high species richness and endemism. Most studies have either invoked paleoclimatic conditions or climatic stability in the southern WG refugium to explain this high diversity and endemism. However, the factors driving macroevolutionary change remain unexplored for most taxa. Here, we generated the most comprehensive dated phylogeny to date for ranoid frogs in the WG and tested the role of paleoclimatic events or climatic stability in influencing frog diversification. We found that the diversity of different ranoid frog clades in the WG either accumulated at a constant rate through time or underwent a decrease in speciation rates around 3–2.5 Ma during the Pleistocene glaciation cycles. We also find no significant difference in dive..., , , # Diversifying in the mountains: spatio-temporal diversification of frogs in the Western Ghats biodiversity hotspot

This repository contains two folders that contain all the data and scripts used to perform the analyses in the article.\
Details of the two folders are provided below.

## 1. WG\_frog\_trees folder

This folder contains the dated tree of Ranoidea generated during this study and the pruned trees of the six Western Ghats clades (Nyctibatrachus, Micrixalidae, Ranixalidae, Raorchestes, WG-Ranidae and Uperodon) analysed individually in the paper.

## 2. Data\_and \_Rscript folder

This folder contains all the data and R scripts used to run all the analyses.
