A Recent Lineage Split in <i>Cladium mariscus</i> Preceding the Disjunction of Two Biodiversity Hotspots: Evidence From Plastid Genomes. [PDF]

open access: yesEcol Evol
Our complete plastome analysis of Cladium mariscus reveals a Late Pleistocene divergence (~68.5 kya) between disjunct Tibetan (Bomi) and Yunnanese (Ninglang) populations—predating the tectonic disjunction of the Hengduan and Yarlung Tsangpo biodiversity hotspots.
