Background Pinus koraiensis Siebold & Zucc. (Korean pine) is a key species of the mixed cold temperate forests of Northeast Asia. Current climate change can significantly worsen the quality of P. koraiensis habitats and therefore lead to a large-scale structural and functional transformation of the East Asian mixed forests. We built a species distr...

The first complete and updated checklist of vascular plants of Asian Russia is compiled. It is based on “Checklist of Flora of Asian Russia: Vascular Plants” (Baikov 2012) but incorporates numerous floristic, taxonomic and nomenclatural novelties. The territorial scope of the checklist is constituted by three federal districts of Russia (Ural, Sibe...

Questions: South Manchurian mixed forests (SMMFs) are among the most species-rich forest ecosystems in the world's temperate zone. These forests are experiencing significant degradation and have largely been replaced by secondary forests or agricultural lands and anthropogenic non-forest vegetation. A precise quantitative assessment of the remainin...

The boreal biome surrounds the Northern Hemisphere as a broad belt, between temperate and arctic biomes. The boreal landscape is covered mostly by forests and extensive peatlands, often underlain by permafrost. It is characterized by a cold climate with relatively short summers and long winters. Boreal forests are dominated by relatively few conife...

The vegetation of the Kuril Islands remains insufficiently explored due to their remote location and harsh environment. Understanding the factors that influence vegetation distribution in this extensive volcanic chain of islands, spanning over a thousand kilometers, is important for global biogeography. Our paper presents the first vegetation map o...

It has been controversial whether Betula tatewakiana, a dwarf birch distributed in Hokkaido of northern Japan, is an endemic species or a synonym of B. ovalifolia broadly distributed in northeast Asia. The endemic hypothesis is based on the idea that B. tatewakiana is diploid while B. ovalifolia is tetraploid and that they are separated based on th...

In northeast Asia, substantial portion of the floras, including endangered species, are shared among its component countries in the continental, peninsula, and island parts largely through Quaternary migration. To effectively conserve nationally endangered plants in Northeast Asia, transnational conservation studies are vitally needed. Lychnis wilf...

I invite you to the 63rd IAVS annual symposium in Vladivostok, Russia, the last pristine temperate region in the northern hemisphere.
