The volatile secondary metabolites emitted from the buds of 22 different species and two varieties of birch were analyzed using headspace solid-phase microextraction and gas chromatography-mass spectrometry (HS-SPME/GC-MS) methods. The volatile compositions of 21 birch buds are reported for the...

The taxonomy and phylogeny of the Betula L. genus remain unresolved and are very difficult to assess due to several factors, especially because of frequent hybridization among different species. In the current study, we used nucleotide sequences of two internal transcribed spacer regions (ITS1 and...

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...

Daily dynamics of leaf (K_L) and soil-to-branch hydraulic conductance (K_S-B) was investigated in silver birch (Betula pendula Roth.) using evaporative flux method in situ: water potential drop was measured with a pressure chamber and evaporative flux was estimated as sap flux density measured with...

Numerous plant genera have a history including frequent hybridisation and polyploidisation (allopolyploidisation), which means that their phylogeny is a network of reticulate evolution that cannot be accurately depicted as a bifurcating tree with a single tip per species. The genus Betula, which...

Samples of detrital lignite have been collected for detailed organic geochemical and carbon isotope analyses from the First Lusatian lignite seam at the Adamów, Jóźwin IIB and Tomisławice opencast mines, deposited after the last peak of the Mid-Miocene Climatic Optimum. Carbon isotopic compositions ...

Cortinarius is one of the most species-rich genera of mushroom-forming fungi. Based on phylogenetic and morphological evidence, Cortinarius, sect. Riederi, is introduced at sectional level (=subsect. Riederi sensu Brandrud & Melot). The taxonomy, phylogeny, ecology and distribution of not only...

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...

Birches (Betula) are ecologically important plants in the Indian Himalayan Region, but they are still not fully understood from the taxonomic point of view. To provide a basis for taxonomic research, we present a taxonomic synopsis of Betula in India and an account of the material on which the...

During our survey into the diversity of woody litter fungi across the Greater Mekong Subregion, three rhytidhysteron-like taxa were collected from dead woody twigs in China and Thailand. These were further investigated based on morphological observations and multi-gene phylogenetic analyses of a...
