Samsun İlinde İz Element Konsantrasyonlarının Likenler Kullanılarak Biyolojik Olarak Belirlenmesi

Lichens have been widely used in biomonitoring studies. In this study, Cd, Cu, Pb and Zn concentrations in some foliose and fruticose lichens which are found in Samsun were investigated and the differences among the species in terms of trace element concentrations and possible interactions among heavy metals were also examined. The results of the present study show that the study area is polluted by Pb and Cd. The cadmium contamination levels were also higher than those of the other elements. The highest Pb (101.39 ppm), Cu (43 ppm) and Zn (67.60 ppm) levels were found in Physcia adscendes. In addition to this, Hypogymnia physodes is one of the foliose species and the best accumulator of Cd (245.73 ppm) as compared to the other species.Likenler biyomonitör çalışmalarında yaygın olarak kullanılırlar. Bu çalışmada, Samsun ilinde yaygın gösteren bazı yapraksı (foliose) ve dalsı (fruticose) likenlerde Cd, Cu, Pb ve Zn konsantrasyonları ve iz element konsantrasyonları açısından türler arasındaki farklılıklar ve ağır metaller arası muhtemel etkileşimler incelendi. Mevcut çalışmanın sonuçları çalışma alanınınn Pb ve Cd tarafından kirlendiğini gösterdi. Kadmiyum kirliliği seviyeleri diğer elemetlerinkinden yüksektir. En yüksek Pb (101.39 ppm), Cu (43 ppm) ve Zn (67.60 ppm) seviyeleri Physcia adscendes'de bulundu. Buna ilave olarak, yapraksı türlerden birisi olan Hypogymnia physodes diğer türler ile karşılaştırıldığında en iyi Cd (245.73 ppm) biriktiren türdür

The classification of some plants subjected to disturbance factors (grazing and cutting) based on ecological strategies in Turkey

WOS: 000427112700010The effect of disturbance factors such as grazing and cutting were investigated in some plants in central Black Sea Region of Turkey using Grime's CSR strategies and Ellenberg's indicator values (EIVs). Grime's CSR strategies were also determined by Pierce et al.'s (Funct Ecol 27:1002-1010, 2013) scheme because there were some inconsistencies between Grime's and Pierce et al.'s schemes. Secondary strategies in the study area found to be dominant and the dominance of secondary strategies are consistent with "intermediate disturbance hypothesis". All the EIVs were found to be significantly different in grazed vs non-ungrazed and cutted vs uncutted areas. PCA diagram showed that ungrazed and cutted areas are associated with EIVR, while grazed and uncutted plots are associated with EIVL, EIVM, EIVN and EIVT.Amasya UniversityAmasya University [FMB-BAP-14-067]; Amasya University Research FundAmasya UniversityThis study is supported by Amasya University Project number (FMB-BAP-14-067).
