Sclerophylly in Quercus cerris L. var. cerris and Phillyrea latifolia L. and edaphic relations of these species

In this study foliar sclerophyll indexes, N %, P % and K % concentrations and correlations between sclerophyll index and these parameters were investigated in Quercus cerris L. var. cerris and Phillyrea latifolia L. In addition to this soil samples were collected and some physical and chemical analysis were carried out in these samples. Finally it has been determined that sclerophyll index was correlated with leaf N % concentrations in Q. cerris var. cerris and P. latifolia and leaf K % concentration in Q. cerris var. cerris.

Effects of selected groundwater chemical traits on a salt marsh community

Effects of selected groundwater chemical traits on a salt marsh community Electrical conductivity, exchangeable sodium ratio and water depth have negative impacts, whereas soil organic matter concentration has a positive impact on Black Sea salt marsh vegetation. The most saline soils were characterized by Salicornia prostrata vegetation and associated with exchangeable sodium ratio. Alhagi pseudalhagi and Tamarix smrynensis populations were associated with water depth, while Juncus littoralis, Ammophila arenaria and E. paralias were associated with soil organic matter. Euphorbia paralias, Ammophila arenaria and Iris orientalis were associated with acidity.

Mountainous Vegetation of Central Black Sea Region

Central Black Sea Region includes many different vegetation types. At high elevations, forest vegetation is dominant. Some forest types have closed canopies, while some of them can be disturbed mainly due to anthropogenic factors (grazing, clear-cutting, etc.). Oceanic climate is seen in northern slopes, while continental climate is also seen especially in inner parts of the region. Continental climate is also seen in inner parts of stream valley (e.g., Kizilirmak valley). Mediterranean climate is also penetrated in inner parts of the region. As a result of this, it is impossible to draw a demarcation line among different vegetation types. For example, some forest communities include Euxine, steppe, and Mediterranean-type communities and phytosociological classification is too difficult.
