Behavioral and genomic footprints of strong reproductive isolation via acoustic communication in two sympatric hybridizing frog species

The supplementary data files submitted herein contain the following detailed research data on the Pelophylax nigromaculatus and P. plancyi: field ecological observations, acoustic characteristic analyses, morphological measurements, and whole-genome resequencing results. The complete experimental procedures for obtaining and processing these data have been described in detail in the "Materials and Methods" section of the manuscript.
