Reflection of climatic changes during interpleniglacial in the geoecosystems of South-Eastern Poland

-Eastern Europe is located in a transitional zone from oceanic to continental climate, where during the cold stages of the Quaternary the expansion of continentality was westward. During the last cold stage this part of Europe was invaded twice by the Scandinavian ice sheet that made the boreal forest recede towards the South-East in relation to continental permafrost expansion to the West. The simultaneous expansion of steppes from the Pontian area to the Carpatho-Dinaric region (with intramountain basins) resulted in the formation of vertical zonality, characteristic also for

First record of Hydrogonium gregarium (Pottiaceae, Bryophyta) in Russia: an interesting extension of the species’ distribution to the heart of the permafrost zone


Hydrogonium gregarium (Mitt.) Jan Kučera, previously known from Southeast Asia, Japan, and scattered occurrences in Pacific North America south to Mexico, is reported for the first time in Russia from the central part of Yakutia at the western foothills of the Verkhoyansk Range. Both morphology and nuclear ITS sequence data confirm its identity with H. gregarium var. gregarium. The species is described and illustrated, and its habitat is briefly discussed.
