Transpiration and stomatal conductance in deciduous needleleaf boreal forests of northern Siberia can be highly sensitive to water stress, permafrost thaw, and atmospheric dryness. Additionally, north-eastern Siberian boreal forests are fire-driven, and larch (Larix spp.) are the sole tree species. ...

Female organs of Umaltolepis are recorded from the Middle Jurassic of East Siberia for the first time. A new species, Umaltolepis irkutensis, sp. nov., is described from the Aalenian-Bajocian Prisayan Formation of the Irkutsk Coal Basin. It is notable for having papillae on some subsidiary cells of ...

Relict species play an important role in understanding the biogeography of intercontinental disjunctions. Pterocarya (a relict genus) is the valuable model taxon for studying the biogeography of East Asian versus southern European/West Asian disjunct patterns. This disjunction has not been as well...

On the basis of paleobotanical data obtained from lake and bog deposits in the Lake Golodnaya Guba area, the stages of waterlogging of the paleo water body and the successions of vegetation of Malozemelskaya tundra during the Holocene were characterized. It was established that, in the Early...

The confusing nomenclature of the distinctive conifer Cathaya is outlined and summarized. Cathaya was validated on fossil material by Karavaev in 1961 before its validation on the basis of extant plants in 1962 by Chun & Kuang. Fossil C. jacutica, based on cones from the Miocene sediments of...

In the north-taiga larch forests of Siberia, on permafrost, there is a widespread phenomenon of crown dieback. To reveal the factors causing crown dieback, we have studied the structure of water-conducting system in the stems of stag-headed and healthy trees of Gmelin larch (Larix gmelinii (Rupr.)...

Phaeolus schweinitzii (Fr.) Pat. was originally described in Europe and is considered a common forest pathogen on conifers in the Northern Hemisphere. Our molecular phylogeny based on samples from China, Europe, and North America confirms that P. schweinitzii is a species complex, including six...

Ectomycorrhizal (EM) fungal communities have been studied worldwide; however, those in the very cold and dry continental climate zone of northern Eurasia remain understudied. We investigated EM fungal community structure on plant roots and its determinants in eastern Siberia. We identified 291 EM...

Article analyzes the scientific achievements and heritage of Mikhail Antonovich Shemberg, a well-known dendrologist, who made a great contribution to the study of Siberian forests. He carried out a critical taxonomic treatment of birch Betula L. genus, developed new methodological approaches based...

In this paper, we study the morphological and epidermal features of leaves of Podozamites distans (type species) from two localities near that of the lectotype in Bavaria, Germany whose morphology is identical with the leaves of the lectotype, designated here. Emended diagnoses are provided for the ...
