The soils in the study area are loamy textured with generally slightly acidic (pH(H2O) between 4.29 -6.02) soil reaction. The vegetation types studied were pasture in abandoned agricultural lands, Cystus and Rubus sp. dominated shrubs at shrub land, and mixture of Quercus petrea, Q. cerris, Q. frainetto and Q. robur in the oak forest which was clear-cut. Thirteen sample plots were used to measure net mineralization and nitrification amounts during a month consisting from 3 recently abandoned agricultural lands (RAAL) (no application for 5 years), 3 old abandoned agricultural lands (OAAL) (no application for 20 years), 3 shrub lands (SL) and 4 oak forest lands (OFL). Sampling took place on April 24th and May 22nd in 2009. The 29 d net nitrogen mineralization amounts showed no differences among RAAL, OAAL and SL (0.223, 2.398 and 3.951 mg NH4+-N kg(-1) for RAAL, OAAL and SL respectively), while OFL site produced more amount of net-nitrogen mineralization (10.976 mg NH4+-N kg(-1)) than the others (Tukey, p<0.05). The nitrification amounts also showed similar results with mineralization such as 0.604, 0.434, 0.499 and 2.602 mg NO3--N kg(-1) for RAAL, OAAL, SL and OFL respectively (Tukey, p<0.05). The initial ammonium-N and nitrate-N concentration in the soils showed that for all land use types nitrate was mobile whereas ammonium was more stable mineral nitrogen form. In this study, the initial ammonium and nitrate amounts had a minor effect on the mineralization and nitrification. Amounts of organic carbon amounts were more important than total carbon and mineral nitrogen concentrations in affecting rates of N transformations. In conclusion, microclimatic conditions and differences in organic carbon are likely related to the differences in nitrogen transformation rates we measured.Publication Metadata only A Comporative Study on the Morphology, Anatomy and Ecology of Dactylorhiza romana (Seb.) Soo subsp. romana and Dactylorhiza romana (Seb.) Soo subsp. georgica (Klinge) Soo ex Renz & Taub.

Soo subsp. romana and Dactylorhiza romana (Seb.) Soo subsp. georgica (Klinge) Soo ex Renz & Taub. (Orchidaceae) in Turkey(2012-10-01) ALTUNDAG, ERNAZ; SEVGİ, ECE; KARA, OMER; SEVGI, ORHAN; TECIMEN, HUSEYIN BARIS; BOLAT, ILYAS; SEVGİ, ECEIn this study, 2 subspecies; Dactylorhiza romana (Seb.) Soo subsp. romana and Dactylorhiza romana (Seb.) Soo subsp. georgica (Klinge) Soo ex Renz & Taub. mainly distributed in Turkey were investigated in terms of morphological, anatomical characters and habitat properties. Plant and soil samples of D. romana subsp. romana were taken from 9 localities and D. romana subsp. georgica from 7 localities in Turkey. We observed that some of morphological characters such as; underground part length, tuber length, the longest leaf width, and bract length had different properties between both subspecies. Cross sections of the leaves, stems, tubers and roots were taken by free-hand and stained with Sartur solution and Safranin. The same procedure was performed for the surface sections of leaves and stern. Stomatal and epidermal cells, starch granules dimensions, lengths of raphides, stomata index, and cuticular thickness were measured. Anatomical characters of leaves such as cuticle thickness and stomata index displayed between two subspecies. Although D. romana subsp. georgica grows in high altitudes, D. romana subsp. romana prefers lower altitudes. The most common habitat of D. romana is meadow, macchie and forest lands. We obtained that both of them had similar soil properties, while the differencies came out by habitat properties. Morphological and habitat characters were compared with independent-T test.Publication Metadata only Ethnobotanical uses of genus Pinus L. (Pinaceae) in Turkey(2013-04-01) KIZILARSLAN, Cagla; Sevg, ECE; SEVGİ, ECEPinus brutia Ten., Pinus halepensis Mill., Pinus nigra Arnold, Pinus pinea L. and Pinus sylvestris L. forests cover approximately 10.91 million hectares area in Turkey. Since there are a lot of settlements inside or near these wide Pinus forest lands, the usages of Pinus species are very common among local people. Within this paper, 130 ethnobotanical and traditional medicinal studies published up to 2011 which were dealed different areas of Turkey are examined and the usages of Pinus species are compiled from 54 of them. It has 269 records that are to be proof of the wide range of ethnobotanical usages of pines. Due P. halepensis has a narrow distribution, the records about ethnobotanical usage of it does not exist in the investigated literature.Publication Metadata only SMALL-SCALE SPATIAL PATTERNS OF TWO TERRICOLOUS LICHENS IN A CONIFER PLANTATION(2020-01-01T00:00:00Z) Sevgi, E.; Yilmaz, O. Y.; Sevgi, O.; SEVGİ, ECEVarious studies have been conducted on the factors affecting the spatial distribution of terricolous lichen species at regional and landscape scales, yet not on small-scales. In our study, the distribution of lichens was obtained by objective classification and spatial analysis of RGB camera images taken from two different heights by an unmanned aerial vehicle at a reforested area of 1575 m(2). Black pine and cypress are species that have been introduced, while the, native species are oak and mock privet. The total area covered by Cladonia rangiformis Hoffm., (26.17 m(2)) in the study area was 5 times higher than that covered by the Cladonia foliacea (Huds.) Willd. (5.01 m(2)). These species were found to be located mostly to the north and sometimes at the east of the tree species. C. rangiformis was found under the crown projection area of cypress; however, no such result has been found for black pine, mock privet, and oak. Therefore, tree species affect the distribution of terricolous lichen species. The patch sizes of both of these lichen species fit the power law distribution and demonstrate inhomogeneous spatial distribution in the area. C. rangiformis and C. foliacea patch size classes generally clustered at short distance (2-2.5 meters) and demonstrated regular distribution beyond this distance.
