Aims : To develop a consistent ecological indicator value system for Europe five of the main plant niche dimensions: soil moisture (M), nitrogen (N), reaction (R), light (L) and temperature (T). Study area (and closely adjacent regions). Methods We identified 31 systems vascular plants in that contained assessments on at least one aforementioned dimensions. rescaled values each dimension to continuous scale, which 0 represents minimum 10 maximum present Europe. Taxon names were harmonised...
Abstract The Convention on Biological Diversity ( CBD ) aims at the conservation of all three levels biodiversity, that is, ecosystems, species and genes. Genetic diversity represents evolutionary potential is important for ecosystem functioning. Unfortunately, genetic in natural populations hardly considered strategies because it difficult to measure has been hypothesised co‐vary with richness. This means richness taken as a surrogate planning, though their relationship not properly...
ABSTRACT Aim To evaluate the effect of post‐glacial migration lags on current distribution Alpine plants and factors responsible for possible range‐filling differences among species. Location Austrian Alps. Methods We used species models to predict environmentally suitable sites 183 at a fine spatial resolution (100 × 100 m 2 ). overlaid these predictions with independent mapping data (3′× 5′) calculated extent which fill their potential ranges this coarser grain based several different...
Abstract Aim To test predictions of different large‐scale biodiversity hypotheses by analysing species richness patterns vascular plants in the Austrian Alps. Location The part Alps ( c. 53,500 km 2 ). Methods Within floristic inventory Central Europe were systematically mapped for plants. Data collection was based on a rectangular grid 5 × 3 arc minutes (34–35 Emerging correlated with several environmental factors using generalized linear models. Primary variables like temperature,...
Aim We test for the congruence between allele-based range boundaries (break zones) in silicicolous alpine plants and species-based break zones flora of European Alps. also ask whether such coincide with areas large elevational variation. Location The Methods On a regular grid laid across entire Alps, we determined allele- using respective clustering algorithms, identifying discontinuities cluster distributions (breaks), quantifying integrated densities zones). Discontinuities were identified...
ABSTRACT Aim To test the influence of various species traits, elevation and phylogeographical history on genetic diversity high‐mountain plants in Alps Carpathians. Location The regular sampling grid comprised whole range European Methods Twenty‐two plant were exhaustively sampled their was assessed with amplified fragment length polymorphisms (AFLPs). ANOVAs used to check for relationships between traits diversity, whether influenced by altitude (i.e. versus Carpathians). Results In both...
Summary Plant–plant interactions are increasingly considered as complex phenomena involving both negative and positive components. Within a community, the relative importance of these components is probably species‐specific may also vary among life‐history stages along environmental gradients. We used tree line north‐eastern Calcareous Alps Austria, composed shrubby Pinus mugo upright Picea abies Larix decidua , simple system in which to investigate interactions. focused on largely unknown...
Background: Ecological indicator values (EIVs) have a long tradition in vegetation ecological research Europe. EIVs characterise the optimum of species along major environmental gradients using ordinal scales. Calculating mean per plot is an effective way bioindication. Following first systems Russia and Central Europe, about two dozen EIV been published for various parts Europe. Aims: As there was no system available at European scale that could be used broad- analyses, e.g. context...
New floristic records from the eastern Karavanke/Karawanken and Kamniške Alpe/Steiner Alpen (Slovenia Austria) are reported. Allium kermesinum is new for Austria; Arabis soyeri subsp. subcoriacea, Carex rupestris Draba dubia Alpen; Androsace hausmannii, stellulata, ornithopodoides, Pedicularis rosea, Salix serpillifolia Veronica fruticulosa localities presented. Furthermore, taxonomic problems in Oxytropis sect. pumila sensu lato discussed.
