Discussion:
Comparing the results of three genome scans we found few similarities in genomic patterns among species. Only the tubesnout and threespine had similar genome-wide average FST and\({\overset{\overline{}}{H}}_{E}\)scores, but these similarities did not extend to gene-level patterns, while comparison to the ninespine found no similarities at the genome-wide or gene levels.. Additionally, we found contrasting genome scan patterns for each species and no strong evidence to support convergent evolution. This study highlights how the complexities of evolutionary histories, such as genetic bottlenecks or gene flow from unsampled habitats, can complicate the comparisons of genome scans.
