Publication Metadata only Epiphytic Lichens of Alacam Mountains Blackpine Forest (Balikesir - Kutahya)(2011-01-01T00:00:00Z) ÖZYİĞİTOĞLU, GÜLŞAH; SEVGİ, ECE; Sevgi, Orhan; TECİMEN, Hüseyin Barış; YILMAZ, Osman Yalçın; Acikgoz, Birkan; SEVGİ, ECEThis study was conducted at pure Anatolian black pine (Pinus nigra Arnold subsp. pallasiana (Lamb.) Holmboe) forests of Alacam Mountains (Balikesir-Kutahya) in order to investigate the lichen species on black pine. 471 trees from 95 sample plots were sampled and a total of 37 epiphytic lichen taxa were recorded on barks. 15 taxa are new records for the province of Balikesir and 19 taxa for the province of Kutahya.Publication Metadata only Investigation of lichen populations and their similarity analysis in Serif Yuksel Forest, Turkey(2010-01-01T00:00:00Z) Sevgi, Orhan; Cobanoglu, Gulsah; Sevgi, ECE; SEVGİ, ECESorensen similarity indices of lichen species in Serif Yuksal forest ranged between 0.29 and 0.84. A linear relation was found between species number sum of two lichen populations and their similarity indices, The linear equation is Y=0.0076x + 0.1467 and the R(2) of the equation is 0.2476 which is significant at p<0.001, There has been identified a linear relation between the average similarity index of the sites and fir participation percentage. The obtained equation is Y=0,0009x+0,5271 and the R(2) of the equation is 0,2853 which is significant at p<0.002. In the pure fir stands there has been found a linear relation between the altitude difference and similarity index, The obtained equation is Y=-0.0011x + 0.6962 and the R(2) of the equation is 0.1755 which as significant at p<0.001.Publication Metadata only Morphological, anatomical and ecological studies on some Orchis (Orchidaceae) taxa of Mediterranean region, Turkey(2012-04-01) Sevgi, ECE; Altundag, Ernaz; Kara, Omer; Sevgi, Orhan; Tecimen, Huseyin Baris; Bolat, Ilyas; SEVGİ, ECEIn this study, nine species mainly distributed in Mediterranean (+ Aegean region) region of Turkey were investigated in terms of 15 morphological, 16 anatomical and 5 ecological characteristics. Those species are Orchis anatolica Boiss., Orchis italica Poiret, Orchis laxiflora Lam., Orchis mono L. subsp. mono, Orchis provincialis Balbis ex DC., Orchis purpurea Hudson, Orchis sancta L., Orchis simia Lam., Orchis tridentata Scop. In conclusion, we found that O. laxiflora was characterized by the longest plant height and O. purpurea had the biggest tuber; whereas O. italica was identified by the highest number of leafs and O. purpurea had the longest leaf length and widest leaf width. Additionally, the other species which were characterized by different morphological and anatomical parameters are as follow: O. sancta with the longest bract length, O. italica and O. simia with the longest sepal lengths, O. laxiflora with the shortest and widest labellum, O. simia with the longest petal length, O. sancta with longest caudiculum length, O. anatolica with the longest spur length and O. provincialis with the longest ovary length. Particularly, O. laxiflora and a purpurea species present essential divergence from the aspect of anatomical features of leaf surface in comparison with the other species. Morphological and anatomical traits of the species were attributed to the habitat selections of the species since that character differs along with each species.Publication Metadata only Effects of growing site parameters on vessel elements of Quercus ilex through Turkey and evaluating in respect of forestry(2021-10-01T00:00:00Z) Akkemik, Ünal; Genç, Sena; Yılmaz, Osman Yalçın; Selvi, Erşan; Yılmaz, Hatice; Sevgi, Ece; Sevgi, Orhan; Akarsu, Ferdi; SEVGİ, ECEPublication Metadata only Some soil physical and chemical properties of natural stands and plantations at different ages of stone pine in Biga (Çanakkale-Turkey)(2018-06-01) Tecimen, Barış; Sevgi, Orhan; Akkaya, Muhammet; SEVGİ, ECE; KIZILARSLAN HANÇER, ÇAĞLA; ALTUNDAĞ ÇAKIR, ERNAZ; SEVGİ, ECE; KIZILARSLAN HANÇER, ÇAĞLAPublication Metadata only Studies on the chorology, ecology, morphology and conservation strategies of Orchis anatolica Boiss (Orchidaceae)(2012-04-01) Altundag, Ernaz; Sevgi, ECE; Kara, Omer; Sevgi, Orhan; Tecimen, Huseyin Baris; Bolat, Ilyas; SEVGİ, ECEOrchis anatolica Boiss. is one of the Mediterranean species, which has wide distribution in Turkey. In this study, plant and soil samples of O. anatolica were taken from 26 natural populations in Turkey. There were one hundred ninety locality records in the Mediterranean region of Turkey, but we recorded two hundred sixteen localities thus adding twenty six new localities to the list. Twenty morphological parameters of O. anatolica were evaluated. The correlation coefficients between generative characters and vegetative characters were lower than the character groups of correlation coefficients between themselves. It is found from sea level upto 1700 m. Most common habitats of O. anatolica are macchie, forest lands and stony soils. The soils are loamy, clayey- loam and sandy-clayey- loam and rich in organic matter. The pH of the soils varies from 5.87 to 7.92. Although O. anatolica has wide distribution in Turkey, different types of land uses are posing a threat for it and restricting its distributional area. Lacking the legal regulations about conservation of the O. anatolica populations is one of the most striking requirement.
