We present a comprehensive review of the characteristics and structure Eurasian steppe its evolutionary history in space time. During last decades, tremendous advances research methods earth palaeontological sciences have greatly increased knowledge on palaeoclimates palaeoenvironments Cenozoic era. discuss well-known facts against background recent progress made these fields others related to our topics, address open questions. In Part I (Status quo), we deal with classification systems,...
In the last few years, biogeography of many European plant species has been analyzed using molecular markers, and some consistent patterns Pleistocenic differentiation range fluctuations have established. These studies mostly focused on perennial herbs or woody species, rarely considering annual taxa. This study Microthlaspi perfoliatum, which is distributed all over Europe comprises three cytotypes. Morphologically, these cytotypes are hard to distinguish, although, based they should be...
Abstract Constituting one of Earth’s major biomes, steppes are characterised by naturally treeless extra-tropical vegetation. The formation the Eurasian steppe belt, largest region in world, began Central Asia during Neogene. In glacial stages Pleistocene, displaced forest vegetation, which turn recolonised area warmer interglacial periods, thus affecting distribution plants adapted to these habitats. Krascheninnikovia ceratoides (Chenopodiaceae) is a plant characteristic dry and semi-desert...
Krascheninnikovia ceratoides (Chenopodiaceae) is a steppe and semi-desert plant with two subspecies, K. subsp. ceratoides, which widespread in Eurasia, lanata, grows western central North America. A few disjunct populations of are found Anatolia, Europe Africa to the west its otherwise continuous Eurasian distribution. To understand evolutionary history this characteristic plant, we analysed phylogeny biogeography. We sequenced several loci including ITS, ETS chloroplast intergenic spacer...
Abstract The Euro-Siberian steppe flora consists of warm- and cold-adapted species, which may have responded differently to Pleistocene glacials interglacials. Genotyping-by-sequencing individuals from across the distribution range pheasant’s eye ( Adonis vernalis ), we aimed gain insight into florogenesis based on species’ evolutionary history. Although primary area origin species group comprising A. , villosa volgensis is in Asia, our results indicate that recent populations are not Asian...
By dint of historical herbarium specimens, we show how changes in species and habitat diversity can be reviewed correlated with events. Our work is based on a digital database specimens the BOKU (WHB), which assigned to Pannonian region eastern Lower Austria. The complete dataset (n = 6655 specimens) was analyzed aid statistical methods allowing computational elimination collectors' effects (i.e. unbalanced collecting interests collectors over time; multiple regression analysis, general...
The Euro-Siberian steppes have experienced large-scale range fluctuations due to the climatic changes of Pleistocene that may also fuelled reshuffling past steppe vegetation. These species-rich grasslands were much more widespread during glacials and contracted interglacials, a dynamic which should be reflected by evolutionary history their biota. Astragalus austriacus is species with European-western Siberian distribution an ideal model study florogenesis steppes. Here, we inferred...
Abstract Diet is important for understanding the ecology and evolution of populations. When examining animals’ diets, lowest taxonomic rank (i.e., species level) generally used. However, it questionable whether dietary description varies with respect to plant taxonomy or extent diversity in landscapes. We studied diet Alpine mountain hare ( Lepus timidus varronis ) by analyzing botanical composition fecal pellets comparing results availability food plants. Overall, hares selected ligneous...
Bernhardt, K.‐G. 1995. Seed burial by soil burrowing beetles. — Nord J. Bot. 15: 257–260. Copenhagen. ISSN 0107–055X. This investigation shows the role of digging beetles (Carabidae, Heteroceridae) in myxospermous seeds. Field experiments with containers filled sterilized sand, seeds different plant species and beetles, are used. After six months plots insects were found deeper depths (up to 10 cm depth) than control plots. The study was done belonging newly created sandy land. that can be...
Cyperus fuscus is a representative of threatened ephemeral wetland plant communities in summer-dry shoreline habitats. We compared variation and plasticity traits related to fitness growth plants germinating from the soil seed bank established river secondary anthropogenic Plants sites at rivers, fishponds fish storage ponds were cultivated selfed get homogenous material for germination an environmental manipulation experiment involving three different water regimes. Differences their...
River restoration activities are challenging for the native vegetation and colonization process. The development of invasive alien plant species (IAS) as well pioneer cover seed bank were observed in one year prior to construction a new river bed within first two years after construction, along downstream section Traisen Austria. One completion channel, occurrence IAS above ground decreased while target increased. Furthermore, no seeds detected result proper management soil movement. Despite...
Microsatellite markers were characterized in the extremely specialized ephemeral wetland plant species Cyperus fuscus (Cyperaceae). The will be used for studying population genetics natural vs. anthropogenic habitats, on a European scale, and role of soil seed bank life cycle this species.Twenty-one microsatellite loci established scored two populations, with mean number alleles 2.6 2.9 expected heterozygosity 0.405 0.470, respectively.
