The paper provides data on the fl oristic composition of vegetation in anthropogenic habitats suitable for Erigeron × huelsenii, a spontaneous hybrid between the alien E. canadensis and native E. acris s. str. The study is based on 21 phytosociological relevés (vegetation plots) of 5×5 m size made in 2013–2014 in the Polish part of the Lithuanian Lakeland (north-eastern Poland) using the Braun-...
A phytosociological approach to dry forest and cactus communities on the occidental slopes of the Peruvian Andes is presented in base of 164 plots carried out following the Braun-Blanquet method. From them, 52 have been made recently, and the other 112 were taken from the literature. After a multivariate analysis, using a hierarchical clustering and a detendred correspondence analysis, the Acac...
Detailed plant diversity information is lacking for Africa, as for many other regions in the tropics, therefore we have used our collection and observation databases to search for possible indicator groups. Digitization of specimen label data for Burkina Faso from the Herbarium Senckenbergianum (FR) and the Ouagadougou University Herbarium (OUA) led to a database containing 18 000 specimens. Fi...
Species diversity is one of the most important indices used for evaluating the sustainability of forest communities. This study aims to characterize the forest communities and to identify and compare the plant species diversity in the study area. For this purpose, 152 relevés were sampled by a randomized-systematic method, using the Braun-Blanquet scale. Classification of the vegetation was con...
Bu çalışmada Aralık (Iğdır, Türkiye) karasal hareketli kumul vejetasyonunun üst sintaksonomik birimlerinin analizi yapılmıştır. kapsamda, Braun-Blanquet floristik metoduna uygun olarak kaydedilmiş olan 47 relevé yeniden değerlendirilmiştir. Sinoptik tabloda relevélere kaydedilen taksonların geçerli ve güncel isimleri kullanılmıştır. Değerlendirme sonucu, ilçesinde vejetasyonundan tanımlanan Eup...

Study area The (European part Russian Federation). Methods A total 91 relevés were processed. Most them (73.6%) sampled in during 2016 and 2017, remaining ones (26.4%) historical published data. They classified by means mo...
abstract this paper presents a quantitative account of vegetation–environmental factor relationships in arid rangelands. vegetation cover was recorded using braun-blanquet combined abundance-cover scale in each quadrat. within each quadrat, one profile was dug and soil samples being taken at 0-20cm and 20-100cm depths. under study physical-chemical characteristics included texture, lime, organi...
Vegetation diversity and ecology of grassland communities with Salvia officinalis were assessed in the natural range species Western Balkans, using Braun-Blanquet approach. With aim defining differences among identifying main environmental gradients, cluster analysis (Flexible Beta method) non-metric multidimensional scaling ordination applied. From a total 346 phytosociological relevés (259 us...
Abstract Housing plays a central role in everyday life and the fulfillment of human needs. Temporary housing demand can occur due to migration, extreme environmental events or personal decisions, is expected increase upcoming years. This study aims create general understanding temporary housing. We conducted an integrated comparison 66 international examples via tabulation (table work), interdi...
