<abstract xmlns="http://www.w3.org/1999/xhtml">The Central Anatolian vegetation has diverse site conditions and small-scale plant diversity. For this reason, identification of plant communities is important for understanding their ecology and nature conservation. This study aims to contribute the syntaxonomical classification of the Central Anatolian vegetation. The study area is situated among Güzelyurt, Narköy, and Bozköy (Niğde) in the east of Aksaray province of Central Anatolia in Turkey. The vegetation data were collected using the phytosociological method of Braun-Blanquet and classified using TWINSPAN. The ecological characteristics of the units were investigated with Detrended Correspondence Analysis. Three new plant associations were described in the study. The steppe association was included in <italic>Onobrychido armenae-Thymetalia leucostomi</italic> and <italic>Astragalo microcephali-Brometea tomentelli</italic>. The forest-steppe association was classified under <italic>Quercion anatolicae</italic> in <italic>Quercetea pubescentis</italic>. The riparian association is the first poplar-dominated one described in Turkey and, classified under <italic>Alno glutinosae-Populetea albae</italic> and its alliance <italic>Populion albae.</italic></abstract>

The phytosociology, ecology, and plant diversity of new plant communities in Central Anatolia (Turkey)

<abstract xmlns="http://www.w3.org/1999/xhtml">Based on hierarchical classification of more than 300 phytosociological relevés of basophilic black and (or) Scots pine communities in the Southern, Eastern and Southeastern Alps we described a new association <italic>Rhodothamno chamaecisti-Pinetum sylvestris</italic>, into which we classify stands that have until now been discussed in the framework of subassociations <italic>Fraxino orni-Pinetum nigrae pinetosum sylvestris, laricetosum deciduae</italic> and (partly) <italic>caricetosum humilis</italic>, and are floristically slightly similar also to certain forms of the association <italic>Erico-Pinetum sylvestris</italic>. The stands of the new association are for now classified into Natura 2000 habitat type Southeastern-European <italic>Pinus sylvestris</italic> forests (91R0), within it we propose a special habitat subtype Southeastern-Alpine Scots pine forests, and into a new forest site type Southeastern-Alpine Scots pine forest. At the contact of the Julian and Dinaric Alps we described a new subassociation <italic>Genisto januensis-Pinetum sylvestris campanuletosum cespitosae,</italic> which comprises also a Natura 2000 species <italic>Primula carniolica.</italic></abstract>

Phytosociological analysis of basophilic Scots pine forests in the Southeastern Alps

<abstract xmlns="http://www.w3.org/1999/xhtml">Mantle vegetation includes plant communities dominated mostly by shrubs and occurs in habitats where the typical tree layers meet difficulties to evolve. This study was conducted in three areas of Bulgaria – Western Balkan Range, Western Sredna Gora Mt. and the Fore-Balkan. Numerical classification and ordination were performed by PC-ORD and JUICE software packages. Diagnostic species were determined by calculating the Phi-coefficient. Two associations and one plant community of the <italic>Berberidion</italic> alliance were recognized – <italic>Corno-Ligustretum</italic> Horvat ex Trinajstić ---amp--- Z. Pavletić 1991, <italic>Pruno spinosae-Ligustretum vulgaris</italic> Tüxen 1952 and <italic>Elytrigia repens-Crataegus monogyna</italic> community. The latter considered as a successional stage of shrub encroachment into the grasslands. Its species composition is very close to that of the ass. <italic>Corno-Ligustretum</italic>. The species composition of ass. <italic>Pruno-Ligustretum</italic> represents a mixture of species characteristic for dry and mesic grasslands, fringe and forest vegetation. The <italic>Crataego-Prunetea</italic> class is still poorly studied in Bulgaria and much more data from all regions in the country have to be collected.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The study presents a floristic-sociological classification of the forest vegetation of Kyiv urban area. We identified 18 syntaxa within 7 classes, 7 orders, 8 alliances, and 3 new associations were allocated (<italic>Aristolochio clematitis-Populetum nigrae</italic>, <italic>Galio aparines-Aceretum negundi</italic>, <italic>Dryopterido carthusianae-Pinetum sylvestris</italic>). We analyzed vegetation data using quantitative approaches of ordination and phytoindication. Considering many relevés of transitional nature in the collected data on urban forests, the clustering algorithm of DRSA (Distance-Ranked Sorting Algorithm) was applied to classify vegetation matrix. Large-scale comparative floristic analysis of syntaxa from different regions and countries have been conducted and summarized in differentiating tables.</abstract>

Phytosociological study of the forest vegetation of Kyiv urban area (Ukraine)

<abstract xmlns="http://www.w3.org/1999/xhtml">Extensive tall-trunk orchards, an important element of the central European landscape since the Middle Ages, conserve potential for the future regarding their biodiversity, land use policy and agricultural value. For these reasons, extensive tall-trunk orchards are interesting with regard to nature conservation. Once the management of these low-productivity vegetation sites ceases, the habitat is threatened by successive overgrowth by shrub vegetation. Taking abandoned tall-trunk cherry orchards with dry/mesophilous grassland undergrowth in the locality of Kaňk as an example, the degree of colonization of orchards by woody species and differences in the structure of vegetation cover in different periods after abandonment were monitored. The results showed that the cover of cherry trees in orchards abandoned before 1990 was approximately 30% lower than in orchards abandoned after 2000. The cover of the herb layer in orchards abandoned before 1990 was approximately 60% lower than in orchards abandoned after 2000. The species diversity of orchards abandoned before 1990 was statistically significantly lower than that of orchards abandoned after 2000. The total cover of all species in habitat in areas of medieval ore extraction was approximately 50% lower than that in land originally used for farming.</abstract>
