Giresun dağları Eğribel geçidi alpin çayırlarının florası (Türkiye)

Bu çalışmada Türkiye'nin kuzey-doğu bölgesinde yer alan Giresun Dağları Eğribel Geçidi alpin çayırların florasının tespit edilmesi amaçlanmıştır. Araştırma alanı Avrupa-Sibirya fitocoğrafik bölgesinin Kolşik kısmında yer almaktadır. Sonuçlara göre araştırma alanında; 44 familya ve 138 cinse ait toplam 230 takson tespit edilmiştir. Araştırma alanında en fazla takson sayısına sahip üç familya sırasıyla Asteraceae 39 takson (% 17), Poaceae 28 takson (%12.2) ve Fabaceae 18 takson (%7.9)'dir. En zengin cinsler Trifolium L. ve Ranunculus L. (6 takson), üçüncüsü ise Poa L. (5 takson)' dır. Fitocoğrafik bölgelere göre dağılımlara bakılırsa, taksonların %32.6' sı Avrupa-Sibirya, %18.3'ü İran-Turan, %3.5'i Akdeniz bölgelerine ait olup, %45.6 'sı ise coğrafi bölgesi bilinmeyen veya birden fazla bölgede yayılış gösterenlerdir. Taksonların hayat formlarına göre oranları sırasıyla şöyledir: hemikriptofit %54.4, kriptofit %21.3, kamefit %13.5, terofit %10.4 ve fanerofit %0.4. Endemizm oranı %12.2 (28 takson)'durIn this study it was aimed to determine floristic composition of alpine grasslands of Eğribel Pass in the Giresun Mountains in North-Eastern part of Turkey. The study area belongs to the Colchic Province of the Euro-Siberian phytogeographical region. The vascular flora of Eğribel Pass was studied between 2014 and 2016. According to the results, in the study area 230 taxa belonging to 138 genera and 44 families were identified. The richest 3 families are Asteraceae with 39 taxa (17%), Poaceae with 28 taxa (12.2%) and Fabaceae with 18 taxa (7.9%). The richest genera are Trifolium L. and Ranunculus L. (6 taxa), followed by Poa L. (5 taxa). With 32.6% of the plants belonging to the EuroSiberian Region, 18.3% are of the Irano-Turanian, 3.5% are of the Mediterranean and with 45.6% of the pluriregional or unknown. The life-form ratio of the taxa was as follows: hemicryptophytes 54.4%, cryptophytes 21.3%, chamaephytes 13.5%, therophytes 10.4% and phanerophytes 0.4%. The endemism ratio is 12.2% (28 taxa

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).
