Analysis of the Transdanubian region of Hungary according to plant species diversity and floristic geoelement categories

Abstract

The aim of this study was to describe the proportion of floristic geoelements and plant biodiversity in the macroregions of Transdanubia. The core data source used for the analysis was the database of the Hungarian Flora Mapping Programme. The analysed data were summarized in tables and distribution maps. The percentage of continental elements was higher in dry areas, whereas the proportion of circumboreal elements was higher in humid and rainy parts of Transdanubia. According to the climatic zones, the highest value of continental geoelement group occurred in the forest-steppe zone. The plant species diversity and geoelements were analysed also on a lower scale, with Transdanubia specified into five macroregions. The highest diversity values were found in the Transdanubian Mountain and West-Transdanubian regions because of the climatic, topographic, and habitat diversity.

Checklist Of Fungi Of The Genus Russula From Belarusian-Valdai Lake District

Abstract

The species diversity of the genus Russula Pers. was studied at the northern part of Belarus and the southern part of Pskov region of Russia. The region of the study is characterized by numerous lakes and rugged terrain. The checklist of fungi of the genus Russula is based on the material collected by the author in 1999–2013 as well as the herbarium collections and published data of the other authors. The checklist encompasses 60 species, 28 of these were found to be rare in the area. R. azurea and R. favrei were reported for the first time in Belarus. Nineteen species – R. alutacea, R. atropurpurea, R. aurantiaca, R. brunneoviolacea, R. consobrina, R. fellea, R. grisea, R. heterophylla, R. laeta, R. mustelina, R. nitida, R. pectinatoides, R. pseudodelica, R. pseudointegra, R. rhodopoda, R. rosea, R. sanguinea, R. seperina and R. versicolor were reported for the first time in Pskov region. Most of the listed Russula species are widely distributed in Europe. Most species that are rare in the study region are uncommon in the whole Europe as well.
