Article Mitotyping of Random Bred Cats and Pure Breed Cats (turkish Angora and Turkish Van) Using Non-Repetitive Mitochondrial Dna Control Region(Elsevier, 2024) Bilgen, Nuket; Guvendi, Mervenur; Sezgin, Efe; Can, Huseyin; Koseoglu, Ahmet Efe; Alak, Sedef Erkunt; Un, CemalThe Fertile Crescent appears to be the most plausible region where the domestication of cats commenced through a mutually beneficial relationship between wild cats and early agrarian societies. These domesticated cats then journeyed across the globe mirroring the paths of human migration. An examination of mitochondrial DNA (mtDNA) control region-based mitotyping suggested that a significant majority, exceeding 80%, of globally sampled random-bred and pure-bred cats could be categorized into 12 predominant mitotypes. However, the extent of mitotype diversity within random-bred cats from regions proximate to the Fertile Crescent remains inadequately explored. In light of this we aimed to investigate the mitotype diversity in random bred cats sampled from various regions across Turkey. Additionally, we sought to establish a comparison with the mito-type profiles of locally recognized pure breeds, namely the Turkish Angora and Turkish Van. To unravel their evolutionary narratives, we engaged in comprehensive population genetics analyses at both the individual and mitotype-based levels. Our study encompassed a sample size of 240 specimens, forming the basis for both mitotyping and population genetics scrutiny. Our analysis yielded the identification of nine 'universal' mitotypes (A-J), alongside an 'outlier' mitotype group I. Notably mitotypes A and D emerged as particularly prevalent in contrast to the lesser occurrence mitotypes C, G, and H. With the realm of random bred cats the structure of haplotypes exhibited remarkable diversity presenting distinctions from Turkish Angora and Van breeds. Nucleotide diversity was higher compared to previous reports from Turkey and was one of the highest among reported world cat population estimates. Intriguingly, our investigations did not unveil any pronounced instances of strong selection, population expansions or contractions within any specific population or mitotype. To conclude, our study represents a pioneering effort in uncovering the mitotype profiles and haplotype structures inherent to both random-bred and pure breed cats in Turkey. This endeavor not only broadens our understanding of the feline genetic landscape within the region but also lays the foundation for future inquiries into the evolutionary trajectories and genetic legacies of these feline populations.Article Citation - WoS: 1Citation - Scopus: 1The Current Status of Thrips Parasitoids Ceranisus (hymenoptera: Eulophidae) Species in Turkey Based on Morphology and 28s D2 Rdna(Türkiye Entomoloji Derneği, 2010) Doğanlar, Oğuzhan; Doğanlar, Mikdat; Frary, AnneThe aim of this study was to investigate genetic analysis of the species within genus Ceranisus (Hymenoptera: Eulophidae) that are interesting groups found in South Eastern Anatolia and Eastern parts of Mediterranean Region of Turkey and to compare with the other thrips-parasitoids between May 2006 and May 2007. Totally, 143 specimens (30 male: 113 female) belonging to Ceranisus genus were collected from 20 locations of 38 different localities in Hatay, Gaziantep, Adiyaman and Sanliurfa provinces. The population was divided into 13 groups based on morphologic characters. Phylogenetic relationships amongst Ceranisus species (Chalcidoidea: Eulophidae) were gathered from DNA sequence data. Fifteen species of thrips chalcid parasitoids were analyzed using one gene, D2 domain of the 28S ribosomal DNA. Among morphologically distinct 13 species/taxonomic groups, 3 of them identified as new species according to the genetical analysis. Four of the other species occurred in C. nr. lepidotus group while 5 of C. nr. bozovaensis consisted of two groups. To conclude 3 new species of Ceranisus and 3 different groups that may yield new species were determined in Turkish Ceranisus population.Article Citation - WoS: 73Citation - Scopus: 84Groundwater Contamination and Its Effect on Health in Turkey(Springer Verlag, 2011) Baba, Alper; Tayfur, GökmenThe sources of groundwater pollution in Turkey are identified, and pathways of contaminants to groundwater are first described. Then, the effects of groundwater quality on health in Turkey are evaluated. In general, sources of groundwater contamination fall into two main categories: natural and anthropogenic sources. Important sources of natural groundwater pollution in Turkey include geological formations, seawater intrusion, and geothermal fluid(s). The major sources of anthropogenic groundwater contamination are agricultural activities, mining waste, industrial waste, on-site septic tank systems, and pollution from imperfect well constructions. The analysis results revealed that natural contamination due to salt and gypsum are mostly found in Central and Mediterranean regions and arsenic in Aegean region. Geothermal fluids which contain fluoride poses a danger for skeleton, dental, and bone problems, especially in the areas of Denizli, Isparta, and AydIn. Discharges from surface water bodies contaminate groundwater by infiltration. Evidence of such contamination is found in Upper KIzIlIrmak basin, Gediz basin, and Büyük Melen river basin and some drinking water reservoirs in Istanbul. Additionally, seawater intrusion causes groundwater quality problems in coastal regions, especially in the Aegean coast. Industrial wastes are also polluting surface and groundwater in industrialized regions of Turkey. Deterioration of water quality as a result of fertilizers and pesticides is another major problem especially in the regions of Mediterranean, Aegean, Central Anatolia, and Marmara. Abandoned mercury mines in the western regions of Turkey, especially in Çanakkale, Izmir, Muǧla, Kütahya, and BalIkesir, cause serious groundwater quality problems. © 2011 Springer Science+Business Media B.V.
