Peculiarities of contemporary surface spore-pollen spectra from southern Siberia (Tyva and Khakassia republics)
In mountains and in intermountain depressions in the south of Western Siberia 31 contemporary (subrecent) spore-pollen spectra were collected with aim to reveal how adequate the composition of spore-pollen spectra reflects vegetation types in study area. It was found that pollen spectra from dry ste...

In mountains and in intermountain depressions in the south of Western Siberia 31 contemporary (subrecent) spore-pollen spectra were collected with aim to reveal how adequate the composition of spore-pollen spectra reflects vegetation types in study area. It was found that pollen spectra from dry steppe of Tyva are characterized by dominance of Artemisia and Chenopodiaceae pollen, but more north located steppe of Khakassia – by abundance of Poaceae pollen among herbs and by considerable amount of tree pollen, mostly Betula and Pinus sylvestris.
