Description
Karasal Yaşam Karasal ekosistemleri korumak, iyileştirmek ve sürdürülebilir kullanımını desteklemek; sürdürülebilir orman yönetimini sağlamak; çölleşme ile mücadele etmek; arazi bozunumunu durdurmak ve tersine çevirmek; biyolojik çeşitlilik kaybını engellemek. İnsan yaşamı gıda ve geçim kaynakları bakımından okyanuslara olduğu kadar karaya da bağımlıdır. Bitkiler, insanların besin kaynaklarının %80’ini sağlar, önemli bir ekonomik kaynak ve kalkınma vasıtası olarak tarıma dayanırız. Ormanlar, Yerküre’nin yüzeyinin %30’nu kaplıyor; milyonlarca tür için hayati önem taşıyan yaşam alanları ve önemli temiz hava ve su kaynakları sağlıyor; ve aynı zamanda iklim değişikliği ile mücadele açısından kritik önem taşıyor.

    (2013-04-01) TECIMEN, HUSEYIN BARIS; SEVGI, ORHAN; Yurtseven, Hüseyin; SEVGİ, ECE; SEVGİ, ECE
    This study aimed to compare in situ net nitrogen mineralization and nitrification amounts in different land use types in northern Turkey (Karacakoy-Catalca-Istanbul). 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.

    Comparative Morphological, Anatomical and Habitat Studies on Dactylorhiza romana (Seb.) Soo subsp. romana and Dactylorhiza romana (Seb.) Soo subsp. georgica (Klinge) Soo ex Renz & Taub. (Orchidaceae) in Turkey

    In 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.

    Studies on the Morphology, Anatomy and Ecology of Anacamptis pyramidalis (L.) L.C.M. Richard (Orchidaceae) in Turkey
    (2012-10-01) SEVGİ, ECE; ALTUNDAĞ, ERNAZ; KARA, OMER; SEVGI, ORHAN; TECIMEN, HUSEYIN BARIS; BOLAT, ILYAS; SEVGİ, ECE
    Morphological, anatomical and ecological characteristics of Anacamptis pyramidalis (L.) L. C. M. Richard in Turkey were investigated in this study. Plant materials of A. pyramidalis were provided from 21 native populations between 2007 and 2009 in Turkey, and their localities were recorded. A. pyramidalis samples were evaluated within 19 morphological, 20 anatomical, and 18 soil characters & habitat properties. The findings of this study are as follows: The plant length was minimum 248 mm and maximum 655 Iran, underground part length minimum 23 mm and maximum 140 mm, and number of leaves change between 2 and 14. The leaves were tetrastic, had no trichomes. In surface section of the leaves, the cuticle thickness (abaxial and adaxial), epidermis cell size (abaxial and adaxial) stomata dimensions and stomata index were measured. The epidermal cells- rows were parellel to the midrib. In cross sections of the leaves, upper epidermis was larger than lower epidermis. Vascular bundles were collateral and consist of xylem, phloem and sclerenchyma cells. Raphide bundles were observed in the mesophyll tissue and leaf midrib had lacunas. Chlorenchyma had scattered homogeneously. According to habitat definition of A. pyramidalis it grows from sea level to 1600 m whereas the most common habitat of A. pyramidalis are meadow, macchie and gaps in the forest lands. A. pyramidalis are grown in stony soils and also are rich in clay, and medium in organic carbon. pH of the soils differ from 6.77 to 7.54.

    Effect of Forest Habitat on the Distribution of Lichen Species in Şerif Yüksel Research Forest (Bolu, Turkey)
    (2016-03-01) SEVGI, ORHAN; COBANOGLU, GULSAH; SEVGİ, ECE; SEVGİ, ECE
    The paper presents the results of a study evaluating impact of habitat factors on distribution of lichen species in a forest ecosystem, in Serif Yuksel Research (Bolu-Turkey), by applying -binary logistic regression- as the main analysis tool. The variables used for logistic regression were tree species, forest purity, altitude, slope, aspect, tree diameter and number of lichen species. Since it may only be possible to be installed within the model when the number of surveillance of the species is more than 20 in the study area. Distribution of 42 of the 82 epiphytic lichen species were modeled by logistic regression. It is concluded that among these variables, -number of lichen species- and -to be a mixed forest- were the most appropriate variables used in the models. In conclusion, binary logistic regression model can be successfully used in lichen species distribution in forest habitat.
