ddRADseq of Keteleeria davidiana var. formosana and K. davidiana

Double digest restriction site-associated DNA sequencing (ddRADseq) to investigate adaptive divergence in response to environmental heterogeneityoffive populations Keteleeria davidiana var. formosana, disjunctly distributed in northern and southern Taiwan. Species delimitation between K. davidiana var. formosana and its ancestor, K. davidiana, was also examined.
