Sampling plots were determined via minimal area method, while the vegetation was classified using Braun-Blanquet method. In grouping of sampling plots, cluster analysis in PC-ORD programm was used and three plant groups were found to be present. In determinaion of indicator species within plant groups, indicator species analysis was applied. The vegetation of the study area was grouped into three as degraded forest, shrub and steppe. Degraded shrub and forest vegetation can be discerned by lacking of indicator species. Contarily, the steppe vegetation in which the anthropogenic effect is minimal can be identified by presence of the steppe vegetation indicator...

What is their syntaxonomical position? Can we integrate them into the European vegetation classification system? Which environmental factors are the main drivers of the floristic differentiation of vegetation types?LocationSouthern and western Turkey.MethodsWe collected 4,717 vegetation plots of forest and shrubland vegetation in Mediterranean Turkey and performed an unsupervised classification of this data set. We described vegetation types based on the classification results, expert knowledge and information from the literature. We defined diagnostic species and prepared distribution maps for each vegetation type. To support the interpretation of the vegetation types, we determined the most important environmental variables using canonical correspondence analysis.ResultsThe studied vegetation was divided into 21 types related to three vegetation belts: (a) ...

As journal has only on-line version according to ICPN descriptions are not valid. We described syntaxa: Eryngio falcati-Securigerion securidacae all. nova, Ajugo chiae-Lactucetum serriolae ass. nova, Phlomido grandiflorae-Cistetum salvifolii ass. nova, and Arbuto andrachnes- Quercetum cocciferae ass. nova and selected nomenclatural type for Querco- Phillyreetum mediae Barbero & Quézel 1976.

The essential oils were obtained by the hydrodistillation of the aerial parts of plant samples. The chemical compositions of the essential oils were analyzed with GC-FID and GC/MS techniques. The main chemical compositions were evaluated with the Principal Component Analysis. The relationship between the oil yields, main chemical constituents, and site factors were determined by correlation analysis. A total of 188 compounds and 6 main constituents were detected in the essential oils of S. pisidica. In general, the oils were mostly constituted by monoterpene hydrocarbons, oxygenated sesquiterpene, sesquiterpene hydrocarbons and diterpenes. β - Caryophyllene (0–40.3%), α - pinene (0–27.8%), sabinene (0–17.6%), α...

Tree growth is a process controlled by genetic, environmental and climatic factors. Trees record these signals, which provide valuable scientific data for dendrochronological research. We used raw annual tree-ring width (taken from trees under the age of 100 years) as one of the dendrochronological parameters to compare Juniperus foetidissima and J. excelsa in terms of affecting factors. We compared the annual tree-ring width of both species considering species, locations and research sites of the altitude range of 677–1 400 m a.s.l.. Environmental signals (longitude and latitude, altitude, slope, exposure, human impact and nearest settlement distance), as well as climatic factors (precipitation, temperature, moisture) affecting growth were examined. Results indicate that there is an obvious difference in raw annual tree-ring widths depending on species. J...

The fatty acids fraction was isolated with liquid-liquid extraction from the herb with Folch method and then methylated with BF3 reagent. Linolenic, linoleic, oleic and hexadecanoic acids were found to be the main fatty acids. The unsaturated fatty acids (66.0%) prevailed upon saturated (33.6%) ones. The essential oil was characterized with high percentage of the fatty acids (34.7 %), alkanes (14.0 %) and aliphatic aldehydes (8.3 %). The present study is the first report on chemical composition of C. hamzaoglui lipids and essential oil.
