Low-coverage genome sequencing for selected species of Baikal Region amphipods
Lake Baikal in Eastern Siberia is a well-known biodiversity hotspot. Amphipods (Pancrustacea: Malacostraca: Amphipoda) are the most species-rich group of invertebrates in the lake. In this work, we performed relatively low-coverage (~3x to 13x) sequencing of genomic DNA with DNBSeq for 14 samples of amphipods dwelling in and around Lake Baikal. Among them, there are cryptic species complex Eulimnogammarus verrucosus consisting of three biological species; three other Eulimnogammarus species, E. cyaneus, E. messerschmidtii, and E. vittatus (cryptic species W); Baikalogammarus pullus; and three deep-water scavenger species (Ommatogammarus albinus, Ommatogammarus flavus = Abludogammarus flavus, and Ommatogammarus carneolus melanophthalmus = Pretiositus melanophthalmus) from Lake Baikal. In addition, there are two lineages of Eulimnogammarus oligacanthus, a species inhabiting shallow bays and rivers around Baikal. Finally, there are several species inhabiting water bodies around Baikal, namely a widely distributed palearctic species Gammarus lacustris, and Gammarus dabanus endemic to mountain streams of the Khamar-Daban Ridge. This project includes raw sequencing reads and will be updated with marker sequences extracted from these datasets.
