The taxonomic status of Thamnurgus rossicus was evaluated with respect to the morphologically similar T. petzi using genetic markers. Nucleotide data from the mitochondrial COI gene revealed 2.4% variation between the European Alps and Russian steppe populations. The two nuclear DNA markers CAD and EF1á were identical across populations. In view of their similar morphology, genetic composition,...

A new species Bolanthusturcicus Koç & Hamzaoğlu, sp. nov. was discovered on Hasan Mountain (Turkey, Aksaray province) where it grows on volcanic stony slopes and alpine steppe. its description, images, chorology and ecology, and threat category are provided in this article. It was compared with a closely related species, Bolanthusminuartioides (Jaub. & Spach) Hub.-Mor., Bolanthushuber-morathii ...

Abstract The Kungur forest-steppe is the northernmost outpost of European forest-steppe, located in western pre-Urals within boreal climatic zone. co-existence boreal, nemoral and steppe species with relicts endemics results a high plant diversity, making it an important biodiversity hotspot. Under current climate change strong agricultural impacts, rapidly degrading. In order to develop sustai...

We present a record of pollen and spores coprophilous fungi from sediment core Auel infilled maar, Eifel, Germany, covering the period 42,000 to 36,000 yr b2k. can show that vegetation cover was dominated by boreal forest with components steppe cold-temperate wood taxa. The proportion taxa higher during interstadials, whereas steppe-vegetation became more prominent stadials. During Heinrich sta...
