Abstract
Predator-prey interactions have been suggested as drivers of diversity in different lineages, and the presence of anti-predator defences in some clades is linked to higher rates of diversification. Warning signals are some of the most widespread defenses in the animal world, and there is evidence of higher diversification rates in aposematic lineages. The mechanisms behind such species richness, however, are still unclear. Here, we test whether lineages that use aposematism as anti-predator defense exhibit higher levels of genetic differentiation between populations, leading to increased opportunities for divergence. We collated from the literature > 3,000 pairwise genetic differentiation values across more than 700 populations from over 60 amphibian species. We find evidence that, given the same geographic distance, populations of species of aposematic lineages exhibit greater genetic divergence relative to species that are not aposematic. Our results support a scenario where the use of warning signals could restrict gene flow, and suggest that anti-predator defences could impact divergence between populations and potentially have effects at a macro-evolutionary scale.

Dataset from literature collection of genetic divergence values (Fst) and geographic distances. Geographic distances were calculated from location coordinates using the topodist package, meaning they are topographic distances.
Description of the data and file structure
Each row in the dataset corresponds to a comparison between two populations of the same species. Each row has information of the species used for comparisons, the geographic distance between populations, the marker used to estimate genetic differentiations and the genetic differentiation calculated as an Fst value. We also include information on the average sample size for each study.
Sharing/Access information
Data was derived from the sources listed in Ref-species file.
Methods
Data was collected from publications as described in the manuscript. It was processed using R but raw values can be found in the original publications used.
