Supplementary material from "Marine barriers and seascape features shape diversification in Neotropical cryptobenthic reef fishes"

Because ocean environments often lack clear barriers to dispersal, cryptobenthic reef fishes, with their limited mobility, are ideal for uncovering spatial patterns of evolutionary divergence. We conducted a comparative phylogeographic study of 23 of the 25 known species in the cryptobenthic genus M...

We conducted a comparative phylogeographic study of 23 of the 25 known species in the cryptobenthic genus Malacoctenus, integrating genome-wide SNPs (>500 individuals), geometric morphometrics, and seascape data to evaluate historical and contemporary barriers in the Tropical Eastern Pacific (TEP) and Greater Caribbean (GC).

In the TEP, linear coastlines and broad sandy gaps, such as the Sinaloan, Central American, and Galápagos breaks, consistently restricted gene flow. In contrast, the GC showed more variable structure shaped by currents and its semi-enclosed geography, with pronounced breaks across the Eastern Caribbean, Bahamas, and Gulf of Mexico. Seascape genomic analyses identified depth, temperature, and chlorophyll-α as key environmental drivers, with depth particularly important in separating tide pool- and reef-associated clades.
