Genlight table of ddRADseq-DArTseq Baikal sculpins adaptive radiation

Lake Baikal ranks among the most species-rich freshwater environments on the planet; however, the evolutionary histories of endemic taxa remain poorly understood. The unique abiotic environments of Lake Baikal include the only bathybenthic, bathypelagic, and deep hydrothermal vent communities in freshwater, each of which supports species with derived morphological and physiological traits. As the only vertebrate radiation endemic to a non-tropical ancient lake, the Baikal sculpins represent an underappreciated resource for investigating evolutionary processes that underlie adaptive radiation. We examined morphological and ecological diversity among Baikal sculpins and present the first interspecific phylogeny inferred from unlinked nuclear genomic markers. The new phylogeny supports a holarctic lotic common ancestor to a limnetic radiation, and reveals convergent adaptations to bathyal and pelagic habitats. Ecomorphological shifts involved dramatic modification of skeletal elements, sen...,

## Description of the data and file structure

Folder: Report-DCot20-5454.zip contains a reduced-representation nuclear genotype data set generated for 347 BCR specimens and multiple outgroups using a double digest restriction-site associated DNA sequencing (ddRADseq) protocol developed by Diversity Arrays Technology (DArT). The DArTseq approach uses the methylation-sensitive *Pst*I paired with *Sph*I, a combination designed to enrich the assay with genes that are actively transcribed. Library preparation and DNA fragment enrichment steps were performed by DArT starting from 1 μg of genomic DNA in 50 μL aliquots. Sequencing-by-synthesis technology and proprietary DArTseq algorithms were used to generate fragment consensus sequences (sequence tags) containing binary single-nucleotide polymorphisms (SNPs). Per convention, non-binary S...,
