Abstract

One of the most common plants in the northern hemisphere is the genus Artemisia L. In this article, an analysis of the biodiversity of this genus and its distribution throughout the territory of the Baikal area of Siberia is given. At present, there is no consolidated list of wormwoods for the specified region, much less any analytical publications dedicated to them. Our consolidated list of 55 species of wormwoods is based on our own collection materials, published sources, and electronic databases that are freely available. The current distribution of wormwoods on the territory of the Baikal area of Siberia shows that their concentration occurs according to four biodiversity nodes: Selenginsk–Dauriya, Pribaikalskii, Sayan–Prikhubsugul’skii, and Dauriya–Khenteiskii. The greatest species diversity for Artemisia at 43 was noted in the Baikal node, and the least was noted in the Sayan–Prikhubsugul’skii node at 26, while in the Selenginsk–Dauriya and Dauriya–Khenteiskii nodes, there were 38 each. The Selenginsk–Dauriya node plays a special role in the spread of wormwoods through the migration process. The processes of recent speciation and the endemism associated with these phenomena are more characteristic of the Baikal node; the phenomena of neoendemism and subsequent complex geo- and biochemical processes are caused by Baikal rifting.
