Taxonomic revision of the tribe Triticeae Dumortier (Poaceae) in Turkey

Cabi, Evren
The Triticeae is one of the most important tribes of the family Poaceae. It contains wheat (Triticum L.), barley (Hordeum L.) and rye (Secale L.) which are economically the most important cereals. Although the tribe has been the focus of several systematic studies there has not been a universally accepted taxonomic treatment for the tribe. This research study aiming to revise the tribe Triticeae Dumort. (Poaceae) in Turkey has been carried out by means of collecting specimens from all the localities in Turkey as well as examining the material collected over the years by the other researchers either from Turkey or abroad for a 4 year period starting from June 1th, 2006. All the specimens belonging the tribe were analysed by means of using standart taxonomic methods. This thesis is divided into four main chapters. In the first and second chapters, an introduction and general information about the tribe Triticeae and the material and methods used in the study are given. In the introduction part different taxonomic treatments on the tribe are explained briefly and the recent studies on the genera included in the tribe such as taxonomical, morphological and cytological are explained breifly. In the third chapter of the thesis, the significance of the morphological, micromorphological and ecological data which were used as diagnostic features in the taxonomy of the tribe are explained. Especially, SEM surveys of the glumes and lemma parts found to have great taxonomic values for the systematics of tribe. Distribution and habitat preferences of the tribe are discussed and IUCN threat categories of the taxa are reevaluated along with the types of threats so as to guarantee their sustainability of the rare taxa in Turkey. The fourth chapter covers the revision of the Tribe Triticeae in Turkey. A key for the genera is given. Synonymy, updated descriptions, flowering time, habitat, type citation, general distribution in Turkey, phytogeographical elements, specimen citations on a grid basis and general distribution outside Turkey, are given for each species. Along with general descriptions, keys to species and infraspecific categories are where necessary. In Tribe Triticeae, 18 genera, 79 species, 27 subspecies and 37 varieties have been recognized including 1 new species (Psathyrostachys narmanica Cabi & Doğan sp. nov.), 3 new subspecies (Psathyrostachys fragilis (Boiss.) Nevski subsp. artvinense Cabi & Doğan subsp. nov.; P. daghestanica (Alex.) Nevski subsp erzurumica Cabi&Dogan subsp. nov.; Aegilops triuncialis L. subsp bozdagensis Cabi&Dogan subsp nov.) and 4 new varieties (Agropyron cristatum (L.) subsp. pectinatum (Bieb.) Tzvelev var. mucranatum var. nov.; Eremopyrum bonaepartis (Sprengel) Nevski. var. aristatum Cabi & Doğan; Thinopyrum pycnanthum (Godr.) Barkworth var. aristatum Cabi & Dogan var. nov.; Hordeum spontaneum C. Koch var. anatolicum Cabi & Dogan var. nov. In addition to the taxa new for science, Aegilops juvenalis (Thell.) Eig. and Hordeum spontaneum var. proskowetzii Nábĕlek are recorded for the first time for the Flora of Turkey.


Comparison of 2D and 3D models in application to long wave motion and its interaction with a vertical wall
Çınar, Gizem Ezgi; Yalçıner, Ahmet Cevdet; Baykal, Cüneyt; Department of Civil Engineering (2018)
Tsunami-structure interaction is an important issue in the design of coastal structures. Numerical modeling of the tsunami-structure interaction has a vital importance in this manner to understand the behavior of the long wave motion around structures in a more detailed way. In this study, physical model experiments on solitary wave-vertical wall interaction performed by Arikawa (2015) are numerically studied using two-dimensional depth-averaged non-linear shallow water equations model, NAMI DANCE and three...
Novel insights on demographic history of tribal and caste groups from West Maharashtra (India) using genome-wide data

The South Asian subcontinent is characterized by a complex history of human migrations and population interactions. In this study, we used genome-wide data to provide novel insights on the demographic history and population relationships of six Indo-European populations from the Indian State of West Maharashtra. The samples correspond to two castes (Deshastha Brahmins and Kunbi Marathas) and four tribal groups (Kokana, Warli, Bhil and Pawara). We show that tribal groups have had much smaller effective popul...
A Discussion on Rural Transformation in Turkey
Kurtuluş, Vacide Betül; Şahin Güçhan, Neriman (null; 2019-10-17)
Rural areas represent an indigenous culture and richness of a native society. The environment made by this society is a product of local culture, built by the use of available local materials, considering local production and lifestyle of the villages. Continuity of rural areas is necessary for safeguarding a specific landscape – which has specific features – on earth with its components. A specific landscape can sustain only with a continuous rural life. For a sustainable rural life, the income source of t...
The persistence of a sacred patrilineage in contemporary Turkey: an ethnographic account on the Ulusoy family, the descendants of Hacı Bektaş Veli
Salman, Meral; Şen, Mustafa; Department of Sociology (2012)
This ethnographic study is on a sacred patrilineage, on the Ulusoy family members who are widely accepted by the Alevi Bektaşi communities as the descendants of the eponymous founder of the Bektaşi Order, Hacı Bektaş Veli. In line with the Shi’ite tradition, it is claimed that Hacı Bektaş Veli inherited the batin, the esoteric aspect of the knowledge and the type of spirituality of this knowledge - walaya, by genealogical chain traced back to Ahl-al Bayt, and therefore undertook an initiating and supervisor...
Taxonomic Importance of Seed Morphology in Allium (Amaryllidaceae)
CELEP, FERHAT; KOYUNCU, MEHMET; Fritsch, Reinhard M.; KAHRAMAN, AHMET; Doğan, Musa (2012-10-01)
Allium is one of the largest monocotyledonous genera. Southwest to Central Asia is the major center of diversity for the genus. In the present study, seeds of 62 Allium taxa from Turkey classified in subg. Allium (sect. Allium, sect. Brevispatha, sect. Codonoprasum and sect. Multicaule), subg. Amerallium (sect. Molium), subg. Melanocommyum (sect. Acanthoprason and sect. Melanocrommyum), and subg. Polyprason (sect. Falcatifolio and sect. Scorodon) were examined using light and scanning electron microscopy to...
