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 steppe and forest-steppe vegetation.<strong> </strong>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. The steppe association was included under <em>Onobrychido armenae-Thymetalia leucostomi</em> and<strong><em> </em></strong><em>Astragalo microcephali-Brometea tomentelli</em>. The forest-steppe association was classified under <em>Quercion anatolicae </em>and <em>Quercetea pubescentis</em>. The riparian association is the first poplar-dominated one described in Turkey, was also classified in <em>Alno glutinosae-Populetea albae</em> and in the alliance <em>Populion albae.</em></p> Nihal Kenar Fatoş Şekercil̇er Süleyman Çoban Copyright (c) 2020-01-27 2020-01-27 19 1 1 22 Phytosociological analysis of basophilic scots pine forests in the Southeastern Alps https://ojs.zrc-sazu.si/hacquetia/article/view/7403 <p>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 <em>Rhodothamno chamaecisti-Pinetum sylvestris</em>, into which we classify stands that have until now been discussed in the framework of subassociations <em>Fraxino orni-Pinetum nigrae pinetosum sylvestris, laricetosum deciduae</em> and (partly) <em>caricetosum humilis</em>, and are floristically slightly similar also to certain forms of the association <em>Erico-Pinetum sylvestris</em>. The stands of the new association are classified into a new habitat type Southeastern-Alpine Scots pine forests and a new forest site type Southeastern-Alpine Scots pine forest. At the contact of the Julian and Dinaric Alps we described a new subassociation <em>Genistio januensis-Pinetum sylvestris campanuletosum cespitosae,</em> which comprises also a Natura 2000 species <em>Primula carniolica</em>.</p> Andrej Rozman Igor Dakskobler Urban Šilc Copyright (c) 2020-01-28 2020-01-28 19 1 23–80 23–80 Contribution to the knowledge of Crataego-Prunetea Tüxen 1962 class in Bulgaria https://ojs.zrc-sazu.si/hacquetia/article/view/7267 <p>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 <em>Berberidion</em> alliance were recognized – <em>Corno-Ligustretum</em> Horvat ex Trinajstić &amp; Z. Pavletić 1991, <em>Pruno spinosae-Ligustretum vulgaris </em>Tüxen 1952 and <em>Elytrigia repens-Crataegus monogyna</em> 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. <em>Corno-Ligustretum</em>. The species composition of ass. <em>Pruno-Ligustretum</em> represents a mixture of species characteristic for dry and mesic grasslands, fringe and forest vegetation.</p><p>The <em>Crataego-Prunetea</em> class is still poorly studied in Bulgaria and much more data from all regions in the country have to be collected.</p> Kiril Vassilev Nikolay Velev Momchil Nazarov Copyright (c) 2020-01-28 2020-01-28 19 1 81 97 Classification of the forest vegetation of Kyiv urban area (Ukraine) https://ojs.zrc-sazu.si/hacquetia/article/view/7126 <p>The current study presents the floristic-sociological classification of the forest vegetation of the Kyiv urban area. We identified 21 associations and variants belonging to 7 classes, 8 orders and 10 alliances of the forest vegetation. Some of them were described with new names, particularly, in the classes of <em>Alno glutinosae-Populetea albae</em> (<em>Aristolochio clematitis-Populetum nigrae</em> ass. nov. hoc loco), <em>Robinietea </em>(<em>Galio aparines-Aceretum negundi </em>ass. nov. hoc loco), <em>Galio-Urticetea</em> (<em>Lapsano communis-Urticetum dioicae</em> ass. nov. hoc loco), <em>Quercetea robori-petraeae</em> (<em>Poo nemoralis-Quercetum roboris</em> ass. nov. hoc loco), <em>Vaccinio-Piceetea</em> (<em>Luzulo pilosae-Pinetum sylvestris</em> ass. nov. hoc loco, <em>Calamagrostio epigeii-Pinetum sylvestris</em> ass. nov. hoc loco). Vegetation classification was conducted using the original DRSA algorithm (Distance-Ranked Sorting Algorithm) based on the k-nearest neighbors clustering approach. The phytocoenons were analyzed using ordination, phytoindication, and by inter-cluster similarity evaluation and described by traits of synmorphology, ecological specificity, distribution data, phytosociological spectrum, and syntaxonomical relations.</p> Igor Goncharenko Halyna Yatsenko Copyright (c) 2020-01-27 2020-01-27 19 1 99–126 99–126 Vegetation succession in extensive abandoned tall-trunk cherry orchards: a case study on Kaňk Mountain near Kutná Hora (Czech Republic) https://ojs.zrc-sazu.si/hacquetia/article/view/7440 <p>Extensive tall-trunk orchards, a component of the central European landscape since the Middle Ages, form a biotope to which a number of plant and animal species are bound that are rare in other habitats. 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 composition of vegetation cover in different time periods after abandonment were monitored. The results showed that the cover of cherry trees in orchards abandoned before 1990 was approximately 30% lower than that in orchards abandoned after 2000, and the cover of the herb layer was approximately 60% lower. 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.</p> Markéta Šantrůčková Jiří Dostálek Tomáš Frantík Copyright (c) 2020-01-27 2020-01-27 19 1 127 136 Echinophora spinosa L.
