Central European Vegetation
Plant Formations in the Central European BioProvince Peter Martin Rhind Central European Beech Woodlands Beech (Fagus sylvatica) woods form the natural climax over much of Central Europe where the soils are relatively dry and can extend well into the uplands in the more southern zones. In the north, however, around Sweden it is confined to the lowlands. Beech woodlands are often open with a poorly developed shrub layer, Characteristic ground layer species may include various helleborines such as Cephalanthera damasonium, C. longifolia and C. rubra and sedges such as Carex alba, whilst in others, grasses like Sesleria caerlea or Melica uniflora may predominate, but in some of the more acidic examples, Luzula luzuloides is likely to dominate. There are also a number of endemic ground layer species. For example, in Carpathian beech woods endemics such as Dentaria glandulosa (Brassicaceae), Symphytum cordata (Boraginaceae) and the fern Polystichum braunii (Dryopteridaceae) may be encountered. Fine examples of primeaval beech woods can be found in the limestone Alps of lower Austria including the famous ‘Rothwald’ on the southeastern slopes of Dürrentein near Lunz. These range in altitude from about 940-1480 m. Here the canopy is dominated by Fagus sylvatica together with Acer pseudoplatanus, Picea abies, Ulmus glabra, and on the more acidic soils by Abies alba. Typical shrubs include Daphne mezereum, Lonicera alpigena and Rubus hirtus. At ground level the herb layer is very rich supporting possibly up to a 100 species of vascular plants. Examples include Adenostyles alliariae, Asplenium viridis, Campanula scheuchzeri, Cardamine trifolia, Cicerbita alpina, Denteria enneaphyllos, Euphorbia amygdaloides, Galium austriacum, Homogyne alpina, Lycopodium annotinum, Mycelis muralis, Paris quadrifolia, Phyteuma spicata, Prenanthes purpurea, Senecio fuchsii, Valeriana tripteris, Veratrum album and the central European endemic Helliborus niger (Ranunculaceae). -

Red List of Vascular Plants of the Czech Republic: 3Rd Edition
Preslia 84: 631–645, 2012 631 Red List of vascular plants of the Czech Republic: 3rd edition Červený seznam cévnatých rostlin České republiky: třetí vydání Dedicated to the centenary of the Czech Botanical Society (1912–2012) VítGrulich Department of Botany and Zoology, Masaryk University, Kotlářská 2, CZ-611 37 Brno, Czech Republic, e-mail: [email protected] Grulich V. (2012): Red List of vascular plants of the Czech Republic: 3rd edition. – Preslia 84: 631–645. The knowledge of the flora of the Czech Republic has substantially improved since the second ver- sion of the national Red List was published, mainly due to large-scale field recording during the last decade and the resulting large national databases. In this paper, an updated Red List is presented and compared with the previous editions of 1979 and 2000. The complete updated Red List consists of 1720 taxa (listed in Electronic Appendix 1), accounting for more then a half (59.2%) of the native flora of the Czech Republic. Of the Red-Listed taxa, 156 (9.1% of the total number on the list) are in the A categories, which include taxa that have vanished from the flora or are not known to occur at present, 471 (27.4%) are classified as critically threatened, 357 (20.8%) as threatened and 356 (20.7%) as endangered. From 1979 to 2000 to 2012, there has been an increase in the total number of taxa included in the Red List (from 1190 to 1627 to 1720) and in most categories, mainly for the following reasons: (i) The continuing human pressure on many natural and semi-natural habitats is reflected in the increased vulnerability or level of threat to many vascular plants; some vulnerable species therefore became endangered, those endangered critically threatened, while species until recently not classified may be included in the Red List as vulnerable or even endangered. -

Traditional Ecological Knowledge Among Sami Reindeer Herders in Northern Sweden About Vascular Plants Grazed by Reindeer Berit Inga1 & Öje Danell2
Traditional ecological knowledge among Sami reindeer herders in northern Sweden about vascular plants grazed by reindeer Berit Inga1 & Öje Danell2 1 Department of Wildlife, Fish, and Environmental Studies, Swedish University of Agricultural Sciences, SE-901 83 Umeå, Sweden; Ájtte, Swedish Mountain and Sami Museum, Box 116, SE-962 23 Jokkmokk, Sweden ([email protected]). 2 Reindeer Husbandry Division, Department of Animal Nutrition and Management, Swedish University of Agricul- tural Sciences, Box 724, SE-750 07 Uppsala, Sweden ([email protected]). Abstract: Traditional knowledge about how reindeer utilize forage resources was expected to be crucial to reindeer herders. Seventeen Sami reindeer herders in four reindeer herding communities in Sweden (“samebyar” in Swedish) were interviewed about plants species considered to be important reindeer food plants in scientific literature. Among 40 plant species, which the informants were asked to identify and indicate whether and when they were grazed by reindeer, they identified a total of 21 plant taxa and five plant groups. They especially recognised species that were used as human food by the Sami themselves, but certain specific forage plants were also identified. Detailed knowledge of vascular plants at the species level was surprisingly general, which may indicate that knowledge of pasture resources in a detailed species level is not of vital importance. This fact is in sharp contradiction to the detailed knowledge that Sami people express for example about reindeer (as an animal) or snow (as physical element). The plausible explanation is that observations of individual plant species are unnecessarily detailed information in large-scale reindeer pastoralism, because the animals graze freely under loose herding and border surveillance. -
Part 3. the Daisy Family
Who’s in your family tree? Part 3. the Daisy family All of you will be familiar with the common daisy but did you know it belongs to the largest plant family? Not only that, it is also one of the most advanced flower families in evolutionary terms as well. The Daisy family (also called Asteraceae or Compositae) is composed of an estimated 23,000 species mostly herbs but some shrubs and tree exist too. Several of the species have become important food crops such as lettuce, artichoke and chicory with others being significant ornamental plants such as marigold and chrysanthemum. Sunflowers are commercially significant for their oil and seeds whilst chamomile is made into a soothing herbal tea and echinacea is grown for its medicinal properties. The earliest records are pollen grains found in sediments in Antarctica that date from the Late Cretaceous era about 70 million years ago. The family is regarded as one of the most influential in that many animals, such as bees, wasps and hummingbirds, heavily depend on their flowers to survive. The name of the family - Asteraceae – comes from Greek meaning star and refers to the star-like shape of the flower. A common phenomenon amongst the many species is that their flowers are ‘heliotropic’ meaning they move to track the sun’s path, maximising absorption of the sun’s energy. Flowers From what first seems at first to be a single large flower with enlarged outer petals is actually a dense head of tiny flowers forming a central disc with outer sunray flowers of many smaller flowers. -

An Ecological Database of the British Flora
An Ecological Database of the British Flora submitted by Helen Jacqueline Peat for examination for the degree Doctor of Philosophy Department of Biology University of York October 1992 Abstract The design and compilation of a database containing ecological information on the British Flora is described. All native and naturalised species of the Gymnospermae and Angiospermae are included. Data on c.130 characteristics concerning habitat, distribution, morphology, physiology, life history and associated organisms, were collected by both literature searching and correspondence with plant ecologists. The evolutionary history of 25 of the characteristics was investigated by looking at the amount of variance at each taxonomic level. The variation in pollination mechanisms was found at high taxonomic levels suggesting these evolved, and became fixed, early on in the evolution of flowering plants. Chromosome number, annualness, dichogamy and self-fertilization showed most variance at low taxonomic levels, suggesting these characteristics have evolved more recently and may still be subject to change. Most of the characteristics, however, eg. presence of compound leaves, height and propagule length showed variance spread over several taxonomic levels suggesting evolution has occurred at different times in different lineages. The necessity of accounting for phylogeny when conducting comparative analyses is discussed, and two methods allowing this are outlined. Using these, the questions: 'Why does stomatal distribution differ between species?' and 'Why do different species have different degrees of mycorrhizal infection?' were investigated. Amphistomaty was found to be associated with species of unshaded habitats, those with small leaves and those with hairy leaves, and hypostomaty with woody species, larger leaves and glabrous leaves. -
