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.

Contribution to the knowledge of the syntaxonomy and ecology of macchie and forest vegetation in Paphlagonia, North Anatolia, Turkey

Abstract In this study, the vegetation of Boztepe Forest Protection Area (Unye/Ordu, Turkey), which is located at the middle part of Black Sea region, has been investigated from the phytosociological point of view. The vegetation of the study area was analyzed according to Braun- Blanquets method and ordinated by TWINSPAN and CA. We described five associatons belonging to different vegetation types in the study area. These are as follows: Calluno vulgaris—Arbutetum unedonis ass. nov., Hedero helicis—Castaneetum sativae Yurdakulol et al., Rubo caucasici—Quercetum hartwissianae ass. nov., Carpino betuli—Populetum tremulae ass. nov. and Diospyro loti—Alnetum barbatae ass. nov. The diversity index of associations is calculated by Shannon- Wievers diversity formula.
