The syntaxonomic analysis of pine forests with Acer negundo occurring on fluvio-glacial sandy deposits Altai Krai (South-East Siberia) was made based 93 releves. It established that takes a different phytocenotic part in 2 associations, variants, and 6 no-ranked communities 4 classes orders according to the Braun-Blanquet approach. method detrended correspondence (DCA coordination) implemented ...

The syntaxonomic diversity of mountain tundra vegetation within the axial part Polar Urals is described. We distinguished 5 associations and 3 subassociations assigned to classes phytosociological classification. 4 are described for first time: Pediculari lapponicae–Betuletum nanae ass. nov., Dactylino arcticae–Empetretum subholarctici nov. Br yocaulo diverg entis–Vaccinietum uliginosi solorine...

In this paper a survey on the garrigue vegetation dominated by Satureja montana subsp. occurring in Alta Murgia National Park is presented. These communities were compared with those of Ionian Arc ravines. Syntaxonomic, structural, chorological and ecological analyses performed order to achieve proper classification vegetation. A new association here described, Rhamno saxatilis-Saturejetum mont...

Aims : The Vinschgau is the driest inner-alpine valley in Eastern Alps and harbours a unique steppe vegetation. We studied these dry grassland communities aimed to answer following questions: Which plant can be found currently? Do syntaxa described by Braun-Blanquet 1960s still prevail area? Has there been any change species composition over last 40–50 years? Study area Along an approximately 4...

A classification system of the Colchic spruce-fir forests (the Western Caucasus) was developed using Brawn-Blanquet method. Two new associations Dryopterido caucasicae–Abietetum nordmannianae ass. nov., Pruno laucerasi–Abietetum nov. and alliance caucasicae–Abietion all. were proposed after comparative syntaxonomic analysis dark coniferous from Euxine province. Diagnostic species are Acer pseud...

The alliance name Agrostion castellanae has been widely used for nearly sixty years to indicate a type of acidophilic perennial grasslands occurring in the Iberian Peninsula. At present, is classified order Agrostietalia , and class Stipo giganteae-Agrostietea . However, nomenclatural (lectotype) therophytic grassland, namely association Holco setiglumis-Anthoxanthetum aristati that was consist...
