Article Citation - WoS: 3Ecophysiological Properties of Turkish Endemic Centaurea Consanguinea Dc.(Parlar Scientific Publications, 2019) Eskin, Bülent; Özyiğit, İbrahim İlker; Doğan, İlhan; Demir, Göksel; Yarcı, Celal; Serin, MemduhThis physiological and ecological study was performed on Centaurea consanguinea DC. to acquire information about certain characteristics (bioclimatic, edaphic, topographic, biotic etc.) of its habitat and distribution in Turkey, determine the requirements for germination, explore the soil-plant relations and obtain data on certain aspects of its population biology. Plant and co-located soil samples were collected from Amasya and Havza District (Samsun) in Turkey using standard methods. Various analyzes were employed for determining of physical, chemical and biological properties of the plant species and its co-located soils including pH, total protein and electrical conductivity (EC), soil texture, contents of mineral nutrition and other physical and chemical parameters and the results were presented. Nutrient amounts (in %) were found to be in the ranges of 0.01-0.007 for N, 0.0008-0.001 for P, 0.01-0.09 for K, 0.0002-0.0003 for Na in the soils and 2.25 for N, 0.0068 for P, 0.07 for K and 0.02 for Na in the plant, respectively. Also, it was observed that germination ratios of the seeds were depended on various factors.Article Citation - WoS: 4Citation - Scopus: 4Selection of Alternative Landfill Location by Using a Geographical Information System. European Side of Istanbul. Case Study(Technical University of Wroclaw, 2016) Demir, Göksel; Kolay, Umut E.; Ökten, Hatice Eser; Alyüz, Ümmügülsüm; Bayat, CumaOne of the most difficult tasks encountered when implementing waste management practices in Turkey involves the selection of the most suitable area for a landfill. The Geographic Information System (GIS) which possesses the ability to imitate and process economic and environmental constraints, presents itself as a useful and effective decision support tool. This study will utilize the GIS to determine feasible alternative landfill areas on the European side of Istanbul, which has a high density population, showing that accurate selection results can be achieved at lower cost.Article Citation - WoS: 6Citation - Scopus: 8Mineral Element Uptake Status of Endemic Isoetes Anatolica Prada & Rolleri Populations From Bolu-Turkey(Pakistan Botanical Society, 2013) Özyiğit, İbrahim İlker; Doğan, İlhan; Eskin, Bülent; Keskin, Mustafa; Demir, Göksel; Yalçın, İbrahim ErtuğrulIsoetes genus is commonly known as the "quillworts" and considered to be "fern allies". There are about 200-250 species, with a cosmopolitan distribution but often scarce to rare. Isoetes genus members often grow in extremely sensitive aquatic environments such as temporary ponds, streams and lakes. They are therefore good indicators of environmental quality. Isoetes anatolica Prada & Rolleri is an endemic plant grows on calcareous sediment/soil on the edges of seasonal ponds located in a mountainous area near the southern coast of the Black Sea at 1400 m above sea level at Bolu, Turkey. In this study, mineral element uptake statuses of I. anatolica populations were studied on the background of plant-sediment/soil-water interactions. The study materials were collected from the place where this narrow endemic species only lives in the world (Abant Region, Bolu/Turkey) by using standard methods and plant and sediment/soil mineral element measurements (Al, B, Ca, Cu, Fe, K, Mg, Mn, Na, Ni and Zn) were done. ICP-OES was employed for the measurements during the study. Interrelations between mineral element contents in the sediment/soil, water and plant were discussed. The data revealed that I. anatolica is capable of accumulating considerable amounts of certain mineral elements (B, Ca, Mn and Na).
