Diversity and gradients of vegetation of Sivrihisar Mountains (Eskişehir-Turkey)

This study was carried out to determine the plant communities and understand the main topographical driving factors of floristic differentiation in the Sivrihisar Mountains (Eskişehir Province). Vegetation samplings were carried out according to the Braun-Blanquet approach. The relevés were stored in the TURBOVEG database management program. Hierarchical classification was carried out in PC ORD program with Ward’s method and Euclidean distance as a resemblance measure. The diagnostic species were identified by a fidelity measure in the JUICE program. The results of the classification were visualized by ordination techniques in the CANOCO package by using principal component analysis. In conclusion, except for the degraded forest community, all the 7 steppe and 1 scrub plant communities studied were identified and described as new associations. Also, a syntaxonomical scheme for the vegetation of Sivrihisar Mountains was suggested

Classification of forest and shrubland vegetation in Mediterranean Turkey

Questions What are the main vegetation types of forest and shrubland vegetation at the alliance level in Mediterranean Turkey? What is their syntaxonomical position? Can we integrate them into the European vegetation classification system? Which environmental factors are the main drivers of the floristic differentiation of vegetation types? Location Southern and western Turkey. Methods We collected 4,717 vegetation plots of forest and shrubland vegetation in Mediterranean Turkey and performed an unsupervised classification of this data set. We described vegetation types based on the classification results, expert knowledge and information from the literature. We defined diagnostic species and prepared distribution maps for each vegetation type. To support the interpretation of the vegetation types, we determined the most important environmental variables using canonical correspondence analysis. Results The studied vegetation was divided into 21 types related to three vegetation belts: (a) thermo- and meso-mediterranean, comprising coniferous (Pinus brutia, Pinus pinea) and sclerophyllous forests, as well as macchia, garrigue and phrygana; (b) supra-mediterranean, comprising Pinus nigra subsp. pallasiana forests, thermophilous deciduous forests dominated by various oak species and Ostrya carpinifolia, and forests dominated by temperate species such as Fagus orientalis; and (c) oro-mediterranean, comprising forests and shrublands dominated by Abies cilicica, Cedrus libani, Juniperus excelsa and Juniperus communis subsp. nana. Elevation was identified as the main environmental driver of the vegetation pattern. Among climatic variables, the most important are the mean temperatures (annual and of driest, coldest, and warmest quarters), minimum temperature of winter, precipitation of warmest and driest quarters and precipitation seasonality. These factors indicate the decreasing effect of the Mediterranean climate with increasing elevation. Conclusions The vegetation of Mediterranean Turkey is arranged along climatic gradients depending on elevation and the distance from the Mediterranean Sea. Most vegetation types in this area correspond to the syntaxa accepted in EuroVegChecklist, while others were described as new

AKDENİZ TİPİ EKOSİSTEMLERDE YANGIN SONRASI VEJETASYON DİNAMİĞİ

Günümüzde gerçekleşen orman yangınlarının büyük bir bölümünün insan kaynaklı nedenlere dayanıyor olmasına karşın, Akdeniz tipi ekosistemler için yangınlar, tarihsel gelişim ve ekolojik bakış açısı ile ele alındığında, ekosistem döngüsünün doğal bir bileşenidir. Yüzbinlerce yıllık gelişim süreci içinde bu ekosistemler, yangınlara karşı uyum yetenekleri geliştirmişler ve varlıklarına devam etmişlerdir. Yangın sonrası vejetasyon dinamiğiyle ilgili olarak çok sayıda model ve hipotez üretilmiştir. Genel olarak kabul edilen modele göre; Akdeniz tipi ekosistemler, yangın sonrası otosüksesyon (doğrudan yapılanma) süreciyle hızlı bir şekilde yeniden yapılanmakta ve bu doğrultuda zaman içinde yeniden şekillenebilmektedir. Bu bağlamda gerçekleştirilmiş olan bu derleme çalışmada, dünyada beş farklı bölgede yayılış gösteren Akdeniz tipi ekosistemlerde yangın sonrası vejetasyonun gelişim süreci, Akdeniz havzası özelinde ele alınmış ve sahip olduğu özellikler itibariyle değerlendirilmiştir. Anahtar Kelimeler: Otosüksesyon, Ekosistem, Yangın, Akdeniz, Vejetasyo

BİTKİ SOSYOLOJİSİ ÇALIŞMALARINDA KULLANILAN SAYISAL METOTLAR VE BAZI BİLGİSAYAR PROGRAMLARI

Türkiye’deki bitki sosyolojisi çalışmaları, bitki toplumlarını belirleme üzerine yoğunlaşmıştır. Bitki toplumlarının ekolojik, biyolojik ve yapısal özellikleri konularında ise pek çalışma bulunmamaktadır. Bu kapsamda, geliştirilmiş olan sayısal metotlar (ordinasyon-sınıflandırma) ve bu metotların kullanımını olanaklı kılan bilgisayar programları önemli yardımcı araçlardır. Bu metotlar ve programlar sayesinde, bitki toplumlarının sınıflandırılması ve onların ekolojik, biyolojik ve yapısal özelliklerinin ortaya konması çok kolaylaşmıştır. Bu çalışmada, tüm dünyada ve özellikle Avrupa’daki bitki sosyolojisi ve vejetasyon ekolojisi araştırmalarında yoğun olarak kullanılan ordinasyon ve sınıflandırma teknikleriyle, kapsamlı bir veri yönetim sistemi olan TURBOVEG ve bitki sosyolojisi verilerini analiz etmek ve düzenlemek amacıyla kullanılan JUICE programları tanıtılarak, uygulamaları konusunda bilgi verilmeye çalışılmıştır.

This paper contains the original diagnoses of new syntaxa and typifcations ofexisting names of syntaxa from paper “Classification of plant communities alongpost-fire succession in Pinus brutia stands in southern Antalya (Turkey)” thatwas published in Turkish Journal of Botany. As journal has only on-line versionaccording to ICPN descriptions are not valid. We described syntaxa: Eryngiofalcati-Securigerion securidacae all. nova, Ajugo chiae-Lactucetum serriolae ass.nova, Phlomido grandiflorae-Cistetum salvifolii ass. nova, and Arbuto andrachnes-Quercetum cocciferae ass. nova and selected nomenclatural type for Querco-Phillyreetum mediae Barbero & Quézel 1976

An Unusual Case of Carcinoma Erysipelatoides Originating from Gastric Adenocarcinoma

Carcinoma erysipelatoides, also known as inflammatory metastatic carcinoma, is a rare form of cutaneous metastasis. It is most commonly caused by breast carcinoma, but rarely associated with gastric adenocarcinoma. Herein, we report an unusual case of carcinoma erysipelatoides in a 55 year-old female who had been diagnosed with signet ring cell carcinoma of the stomach metastasizing to ovaries
