Background: The impressive adaptive radiation of notothenioid fishes in Antarctic waters is generally thought to have been facilitated by an evolutionary key innovation, antifreeze glycoproteins, permitting the rapid evolution of more than 120 species subsequent to the Antarctic glaciation. By way of contrast, the second-most species-rich notothenioid genus, Patagonotothen, which is nested within the Antarctic clade of Notothenioidei, is almost exclusively found in the non-Antarctic waters of Patagonia. While the drivers of the diversification of Patagonotothen are currently unknown, they are unlikely to be related to antifreeze glycoproteins, given that water temperatures in Patagonia are well above freezing point. Here we performed a phylogenetic analysis based on genome-wide single nucleotide polymorphisms (SNPs) derived from restriction site-associated DNA sequencing (RADseq) in a total of twelve Patagonotothen species. Results: We present a well-supported, time-calibrated phylogenetic hypothesis ... : SNPs_Figure1_MLSNPs used to generate the ML tree shown in Figure 1.SNPs_Figure2_MLSNPs used to generate the ML tree shown in Figure 2.P. guntheri - P. brevicauda_Figure3a.structureSNPs used in STRUCTURE to generate Figure 3 aguntheri-brevicauda_Figure3a.structure.tsvP. ramsayi - P. wiltoni_Figure3b.structureSNPs used in STRUCTURE to generate Figure 3 bramsayi-wiltoni_Figure3b.structure.tsvL. squamifrons - L. kempi_Figure3c.structureSNPs used in STRUCTURE to generate Figure 3 csquamifrons-kempi_Figure3c.structure.tsvSNPs_Figure4_SNAPPSNPs used in SNAPP to generate tree shown in Figure 4Additional_file4_PoMoInput file used in the software IQtree to generate the tree shown in the additional file4. ...
