Phytosociological survey of juniper wood vegetation in Tajikistan (Middle Asia)
2022
The paper presents the first syntaxonomic classification for juniper wood communities in Tajikistan with some remarks on their environmental gradients. A total of 119 relevés were sampled between 2015 and 2021 using the seven-degree Braun-Blanquet cover-abundance scale. They were classified by a modified TWINSPAN method. Diagnostic species were identified using phi coefficient as a fidelity measure. Detrended Correspondence Analysis (DCA) was used to determine relationships between samples, vegetation units and major gradients in species composition. Plant communities have been divided into two main groups. The first one is a west Irano-Turanian wood of Juniperus polycarpos var. seravschani…
The orophilous communities of the Pino-Juniperetea class in the Central and Eastern Mediterranean area
2001
Orophilous plant communities of the Pino-Juniperetea class, occurring in the Central and Eastern Mediterranean area, are examined. This vegetation is characterized by the dominance of trees and shrubs, mostly represented by conifers belonging to the genera Juniperus, Abies and Pinus. These communities are nowadays relegated to the supra- and oromediterranean belt, and show a fragmentary distribution, which is an evident proof of their relict connotation. The comparison among these communities, based on original and literature data, has highlighted a remarkable floristic and structural homogeneity, together with a series of geographical vicariances. From the phytosociological point of view, …
Biodiversity of the orophilous communities of Pino-Juniperetea class in the Central and Eastern Mediterranean area.
2000
The authors examine the orophilous communities, occuring in the Central and Eastern Mediterranean area, characterized by the dominance of trees and shrubs belonging to the genera Juniperus, Abies and Pinus. These communities are localized in the supra- and oromediterranean belt and show a relict role. From the structural point of view, this kind of vegetation is usually bistratified, with a low dense shrubby layer and spaced tree layer; sometime the latter one is absent. This vegetation is floristically poor and characterized by prevalence of Coniferous, such as Juniperus sabina, J. foetidissima, J. excelsa, J. oxycedrus. J. hemisphaerica, J. communis, J. nana, Abies nebrodensis, A. alba, A…
