Seabirds are located at the top of the food web of coastal ecosystems. Therefore, the distribution and abundance of seabird populations is an important indicator of wellbeing of the marine ecosystems and the anthropogenic impacts on them. Audouin’s gull (Larus audouinii) has experienced a sharp population decline in 1960's. Although its Western Mediterranean population size has recently recovered; Audouin’s gull population is still not stable and there is not enough information on dispersal and status of its breeding populations in the Eastern Mediterranean coasts. The aim of our study is to survey breeding Audouin’s gull colonies along the coasts of Turkey and to elucidate the genetic structure of these populations, gene flow among each other and relationship with Western Mediterranean populations by using microsatellite loci and mitochondrial D-Loop region. We surveyed all 21 islands and islets along the South East coastline of Turkey from Taşucu, İçel to Gazipaşa, Antalya in late May 2016 and recorded their habitat characteristics and breeding bird colonies. One colony of Audouin's Gull and seven colonies of Yellow-legged gull (Larus michahellis) has been recorded and feather samples were taken from the chicks for genetic analyses. The relationship between habitat characteristics and abundance and distribution of breeding gull colonies will be discussed. Heterozygosity levels, phylogeny and gene flow among populations will be elucidated by using fragment analysis data of microsatellite markers and sequence data of D-Loop region. Moreover, signatures of genetic botlleneck and also phylogeography of Audouin’s gull in the whole Mediterranean will be analyzed.

Ada martısı (larus audouinii) Doğu Akdeniz popülasyonlarının yakın dönemli değişikliklerinin genetik yöntemler kullanılarak anlaşılması Yapan, Batuhan Çağrı; Perktaş, Utku; Karahan, Arzu; Oro, Daniel; Özkan, Korhan (2016-06-03) "Besin zincirinin üst basamaklarında bulunan deniz kuşlarının varlığı ve yayılışı, kıyı ekosistemlerinin sağlığının ve insan faaliyetlerinin deniz ekosistemi üzerindeki etkilerinin izlenmesinde büyük öneme sahiptir. Geçtiğimiz yüzyılda birçok deniz kuşu türü insan faaliyetlerinin doğrudan veya dolaylı etkileriyle üreme alanlarını kaybetmiş ve tükenme tehlikesiyle karşı karşıya kalmıştır. 1960larda birey sayısı 600 çifte kadar gerileyen Ada Martısı (Larus audouinii) da bu türlerden biridir. Her ne kadar günü...
Evaluation of salt tolerance in sto transformed Arabidopsis thaliana and Nicotiana tabacum plants Selçuk, Feyza; Yücel, Ayşe Meral; Department of Biology (2004) Salinity is one of the limiting factors of crop development. Together with causing water loss from plant tissues, salinity also leads to ion toxicity. Under salt stress, increase in Ca+2 concentration in cytosol can decrease the deleterious effects of stress. The binding of Ca+2 to calmodulin initiates a signaling cascade involving the activation of certain transcription factors like STO and STZ. This signal transduction pathway regulates transport of proteins that control net Na+ influx across the plasma m...
Subfossil cladocerans as quantitative indicators of past ecological conditions in Yangtze River Basin lakes, China Dong, Xuhui; Kattel, Giri; Jeppesen, Erik (Elsevier BV, 2020-08-01) Cladocerans (Crustacea: Branchiopoda) are an essential component of the food webs of shallow lakes. However, their potential significance as sentinels of environmental change in subtropical regions of South-East Asia, is not well elucidated. In this study, we examined the distribution pattern of cladoceran subfossils in the surface sediments of 64 shallow lakes located in the middle and lower reaches of the Yangtze River Basin (MLYB). Using constrained ordination and multivariate regression trees (MRT), we ...
Genetic characterization of pear cultivars (Pyrus communis) in Çoruh river basin Çoban, Abdulbaki; Kaya, Zeki; Department of Molecular Biology and Genetics (2019) The genus Pyrus contains more than 20 different pear species which are used as food source, horticultural, and ornamental purposes. Overall, pear is the second most consumed pome fruit after apple. P. communis is the most cultivated pear species in Europe and Asia Minor. However, more than 10 species of genus Pyrus can be found naturally in Europe and Asia Minor. In this study, 8 P. communis populations (one wild and 7 cultivated) and 1 P. eleagnifolia population was used to reveal genetic structure of thos...
Comparison Of Recent Past And Present States Of Turkish Shallow Lakes By Using Cladocera Sub Fossil Remainings Sual, Saygın; Çakıroğlu, İdil; Levi, Eti; Bezirci, Gizem; Beklioğlu, Meryem (2016-01-31) Order Cladocera (small crustaceans) has an important place in lake ecosystems as they are both consumers of primary producers and prey for larger predator species. As a result, their abundance is a strong indicator of ecological conditions in a lake at a certain time. Cladocera body parts, such as headshields, shells, etc.) are largely silica based and can be preserved inside the lake sediment for long periods of time. Sedimentary sub-fossil records of Cladocera remains allow us to understand past and more ...
