The role of environmental factors and genetic diversity on colonization success of a non-native fish,Lepomis gibbosus from western part of Turkey

Non-native freshwater fishes may become one of the dominant species in still and slow running waters and may impact whole ecosystem. One such species is the pumpkinseed Lepomis gibbosus, which has become widely distributed throughout Western Europe occurring primarily lakes and reservoirs. Although the species is known to have existed at least for four decades and expanded its distribution range in Turkish waters widely, virtually there is no study on the factors behind the species' establishment success. We hypothesized high environmental tolerance as well as high population structuring result in more successful establishment of pumpkinseed in new environments. We sampled three reservoirs, one canal and one stream located longitudinally along western part of Turkey to test this hypothesis. Optima (uk) and tolerance (tk) levels of the species were calculated with weighted averaging values for several measured environmental factors. Invasiveness of pumpkinseed populations was determined with the model proposed earlier examining the relationship between juvenile growth and age at maturity. The phylogenetic network of mitochondrial haplotypes was constructed for Turkish populations and other populations of pumpkinseed from native (North America) and introduced range (Europe). Potential invasiveness of pumpkinseed populations in Turkey was categorized as invasive in one location (Sarıçay stream) and transitional in other locations. Environmental tolerance values were higher in southern populations. Likewise phylogenetic network showed that the Turkish populations have unique haplotypes, which were originated from native North American populations suggesting a high differentiation in haplotypes. Results clearly demonstrate the effect of environmental factors on genetic structure and the establishment success of pumpkinseed.     

Qurliqnoria (Bovidae,Mammalia) from the Upper Miocene of Çorakyerler (Central Anatolia,Turkey) and its biogeographic implications

New bovid material from the Upper Miocene site of Çorakyerler (Çankırı basin, Anatolia, Turkey) is described and compared here. The described taxon is identified as a representative of the stem caprine genus Qurliqnoria, previously known from the peri-Tibetan area exclusively. The stronger horn-core divergence, weaker anterior keel, smoother horn-core surface, stronger lateral horn-core curvature, stronger and thicker interfrontal suture, less flexed and less pneumatized frontals, and smaller supraorbital foramina differentiate the Çorakyerler Qurliqnoria from the type and only known species of the genus, Q. cheni from China, and demand the erection of a new species, Qurliqnoria chorakensis n. sp. A review of other late Miocene bovid records allows the recognition of Qurliqnoria in Sinap Tepe (Turkey) and Platania (Greece), suggesting a westward propagation of the genus during the Vallesian.     

Trans-Kemalism: the politics of the Turkish state in the diaspora

Abstract

In contrast to the huge amount of research on Turkish migration and migrants, the diasporic politics of the Turkish Kemalist state constitutes a neglected research subject in the scholarship on Turkish diaspora. How does the Turkish state reach out to its nationals and expatriates abroad? In what ways does the Turkish Republic seek to make Islam (as it does in Turkey) into an instrument legitimizing its politicizing and mobilizing enterprises? To explore these questions, this article investigates the long-distance Kemalism engaged in by the Turkish state to Turkify and secularize its nationals in the diaspora, using its activities in Australia as its case study. In sketching out trans-Kemalism's dimensions, the analysis directs attention to the intimate relationship between the political and religious fields of transnationalism manufactured by the state. The paper concludes that the intense political polarization in Turkey in the present makes the future of trans-Kemalism abroad somewhat uncertain.

Prion protein gene (PrP) polymorphisms in healthy sheep in Turkey

Scrapie, a transmissible spongiform encephalopathy (TSE) or prion disease, is a fatal, neurodegenerative disease in sheep and goats. This disease has been known in Europe for more than 250 years. Susceptibility to scrapie is associated with polymorphisms in the sheep prion protein gene (PrP) gene. In sheep, polymorphism in the PrP gene has been identified at a number of codons, and polymorphisms at codons 136, 154 and 171 have reported linkage with susceptibility to scrapie. Polymorphisms at the PrP locus were studied in 413 animals representing three native sheep breeds (Imroz, Chios and Kıvırcık) in Turkey. Genomic DNA was obtained from blood, and genotypes were screened using PCR and direct DNA sequencing. We report 17 genotypes derived from seven different alleles. The most frequent genotype in the Kıvırcık sheep is ARQ/ARQ, whereas the ARR/ARQ genotype is predominant in the Chios and Imroz breeds. In general, the ARQ haplotype was the predominant haplotype. ARQ haplotype was also predominant in the Kıvırcık and Chios sheep breeds, whereas the Imroz sheep predominantly had the ARR haplotype. The susceptibility-associated VRQ haplotype was found in 2.38%, 0.35% and 0.81% of the Imroz, Kıvırcık and Chios sheep, respectively. Moreover, seven additional polymorphisms have been detected at codons G127S, G127V, H143R, G145S, Y172D, N174Y and Q189L. Among these polymorphisms, the N174Y allele is a novel polymorphism, and the G145S allele is a novel allele for a known polymorphic locus.     

Development of biotechnology education in Turkey

For sometime Turkish scientists have been actively involved in biotechnology related research. However, biotechnology educa-tion in Turkey is a relatively recent phenomenon. The subject has not been addressed at the undergraduate level in a serious way until recently. This is evident from the lack of undergraduate degree programmes in biotechnology at Turkish Universities. The Turkish scientific establishment is very much aware of the importance of biotechnology and has identified this subject as one of the priority areas. The Universities are taking positive steps towards enhancing Biotechnology education. This article focuses on the emergence, as well as the problems and prospects of Biotechnology education in Turkey.     

Records and palaeoenvironmental conditions of Early Miocene scleractinian corals from the Fırat formation (Diyarbakır,Turkey)

Miocene scleractinian corals were documented for the first time in the Fırat Formation of Sarıca village, Eğil district of Diyarbakır, SE Turkey. The fauna consists of four hermatypic species belonging to three families: Diploastrea taurinensis (d’Achiardi, 1868), Tarbellastraea reussiana (Milne-Edwards and Haime, 1850), Echinopora gemmacea (Lamarck, 1816) and Montastraea pelouaensis (Chevalier, 1954). The morphospecies described here are typical of the early Miocene (Aquitanian-Burdigalian) and show that the Fırat Formation coral community was composed of shallow and subtropical reefs of Mediterranean Tethys palaeobiogeographical affinity. The examined species are reef components found in tropical and subtropical oceans, as are the majority of zooxanthellae. The species were upper photic zone related, had massive colonial growth morphology, and lived in a shallow tropical-subtropical marine palaeoenvironment at a depth of up to 50 m. They grew on hard ground, clean water, and normal salinity and required a minimum seawater temperature of 18 ̊C; however, they were most abundant at water temperatures ranging from 22 to 26 ̊C in high-moderate water energy. Consequently, this fossil assemblage will not only improve our knowledge of scleractinian coral diversity and morphological variation in SE Turkey but will also provide an important background for future studies of coral taxonomy, diversity and biogeography of the region.     

Nationalism,displacement, and ethnoreligious differentiation in Turkey’s southern borderlands

Drawing on ethnographic fieldwork in Turkey’s southern province of Hatay, near the Syrian border, this paper examines the shifts in the positioning of ethnoreligious differences vis-à-vis Turkish nationalism over the past decade. Hatay was annexed to Turkey from French Mandate Syria in 1939, 16 years after the foundation of the Turkish nation-state, and did not experience the national homogenization that characterized the transition from the Ottoman Empire to the Turkish Republic in the post-WWI era. Its ensuing ethnoreligious diversity with a population composed of bilingual (Turkish-Arabic) Jewish, Christian, Alawi, and Sunni communities characterized the region’s peripheral border status until the new millennium. In this paper, I focus on two major shifts in Turkish politics which reoriented the ethnoreligious identities of these communities. First, I interrogate the short-lived turn to pluralism in mid-2000s to late-2000s when Hatay’s religious diversity gained prominence as an exemplar of Turkish Muslim tolerance. Built on the nostalgia for Ottoman cosmopolitanism against Turkey’s Republican model of nationalism, this regime celebrated the ethnoreligious difference of Hatay’s residents as long as they were identified as representable elements of the nation. I then turn my attention to the emergent ruptures in this discourse of multireligious nationalism with the outbreak of the Syrian War, Turkey’s foreign policy, and the arrival of Syrian refugees in Hatay. In showing how both polities operated within and through rather than replaced the formerly hegemonic understandings of national unity, this paper reveals the constant reworking of national and ethnoreligious identities at the Middle Eastern borderlands.     

The ethnic question in an environment of insecurity: the Kurds in Turkey

This article examines the effect that a poor structural context, what we term an "environment of insecurity", has on the Kurdish ethnic nationalist mobilization in Turkey. The empirical evidence for this analysis is based on data from the 1993 Turkish Demographic and Health Survey [TDHS]. The data provide, to the best of our knowledge, the first reliable and representative figures on the situation of Kurds in Turkey. Our key claim is that the Kurdish population in Turkey is relatively much worse off than the Turkish population in the country. This claim is strongly supported by the data. Many other factors also account for the ethnic nationalist mobilization, but we argue that the Turkish Kurds' environment of insecurity, materially and non-materially, stands out as a key package of both causal and intermediate variables behind the ethnic revival.     

Mitochondrial DNA variation in the western house mouse (Mus musculus domesticus) close to its site of origin: studies in Turkey

In contrast to a substantial inventory of mitochondrial d -loop sequences from the West European part of the range of the western house mouse Mus musculus domesticus , there are few such data from close to the Middle Eastern origin of the subspecies. This paper attempts to rectify this situation, with details of d -loop sequences of 92 mice from 45 localities in Turkey, adding to the six mice from three localities previously studied from that country. The molecular data were found to be consistent with Turkey being close to the site of origin of M. m. domesticus . The 54 Turkish haplotypes were distributed throughout a phylogenetic tree incorporating representative sequences described previously, and there was high nucleotide diversity among the Turkish mice. There was weak genetic structure in Turkey, although haplotypes of the 'Main Turkish Clade', while common over much of Turkey, were absent from Southern Anatolia. Haplotypes of the Main Turkish Clade were also found in western Europe and it is believed that they derived from Turkey, which thus represents one of the source areas for the westwards expansion of M. m. domesticus .  © 2005 The Linnean Society of London, Biological Journal of the Linnean Society , 2005, 84 , 473–485.     

Content Analysis of Printed News Media Related to Drowning Incidents in Turkey

Drowning is a major public health problem in Turkey as it is for other countries. According to the latest statistics, the annual average number of people who drowned in the rivers, lakes, or seas of Turkey is 642. An examination of the language and the presentation style that the media use while covering the news about drowning cases may help us to determine the risk factors of the drowning cases and reduce the number. This study aims to show the awareness level of the Turkish print media on preventing drowning incidents and to discuss the steps to be taken in the Turkish media in order to prevent drowning. To this end, attitudes and presentations of three best-selling newspapers in Turkey—Zaman, Posta, and Hürriyet—and a less-selling one, Cumhuriyet, were studied in accordance with the content analysis method. The results show that the awareness of the Turkish media to prevent drowning incidents is inadequate. The number of drowning cases covered by these newspapers are very few, and they emphasis the forensic aspect of the incidents by using dramatic language without background information.     

Genetic analysis of Turkish martens: Do two species of the genus Martes occur in Anatolia?

Stone marten (Martes foina) and European pine marten (M. martes) occur in western Eurasia. Current distributions of martens within Turkey and phylogenetic relationships among the Turkish and other populations of the two species within Eurasia remain relatively unknown. In this study, we aimed to determine genetic diversity within Martes populations inhabiting Turkey and to reveal the phylogenetic relationships among the Turkish and conspecific populations of the two marten species, using mitochondrial cytochrome b (CytB) sequences. Twenty‐four (24) haplotypes were identified among 86 marten samples collected across Turkey, including 23 novel haplotypes. Genetic distances among the Turkish haplotypes ranged from 0.1% to 0.8%, with an average of 0.3%. The 24 Turkish haplotypes were analysed together with those of conspecific populations deposited in GenBank. Phylogenetic (Bayesian Inference, maximum likelihood, neighbor‐joining) and network analyses revealed that all of the Turkish samples belonged to M. foina and that samples of M. martes were not encountered. Haplotypes of M. foina were divided into five haplogroups. The haplogroup including the two Chinese samples differed markedly from other the haplogroups. The remaining haplogroups contained samples from both the Turkish and European populations. We found that there was a genetically close relationship between the Turkish and the European stone marten populations. As a result of this study, M. martes may not be distributed in the Anatolian part of Turkey, possibly due to a barrier effect of two straits (Dardanelles and Bosporus) and the Caucasus Mountains. On the other hand, M. foina is distributed in both the Anatolian and Thracian parts of Turkey. Our results suggest that Turkey was likely one of the refuges for M. foina during Pleistocene glacial periods and is one of the centres of distribution of stone marten for Europe and the surrounding regions.     

Visual arts education provisions for primary schools in Turkey

This article examines the history of art education in Turkey. Since the beginning, the purposes of the arts and art education have been a point of discussion by various authorities. Whether art education should be taught, and how it needs to be taught, have been at the forefront of educationalists' minds. As a result, introducing certain models of art education has been a challenge. The objective of this article is to present the changes in art education since the 19th century in Turkey. The main focus is on art education practices and policies and an overview of key events in Turkey's history of art education. The article also presents issues related to the importance of visual arts education in Turkish primary school settings. In so doing, this research aims to show readers how past developments helped to create the current visual art education policy in Turkey.     

A review of Turkish saproxylic beetles from the European Red List

The conservation of beetles that depend on dying or dead wood (i.e. saproxylic), has received a great deal of attention in many parts of the world in recent years. Human activities such as urbanization and logging, and their results, e.g. global warming, destroy natural ecosystems and threaten unusual species such as Lucanus cervus (L. 1758), Rosalia alpina (L. 1758), Limoniscus violaceus (Müller 1821) and Osmoderma eremita (Scopoli 1763). Attempts have been made to conserve the habitats upon which these species depend. Although represented by a large number of species, saproxylic beetles in Turkey have not received much attention. Although some Turkish studies have acknowledged their value, comprehensive investigations of these species are very limited. The aim of this study is to make a list, from the literature, of the species that are endangered in Europe and found in Turkey, to highlight the importance of these species. The research includes 151 saproxylic beetle species belonging to the families Bostrichidae, Cerambycidae, Elateridae, Eucnemidae, Scarabaeidae, Euchiridae, Lucanidae and Mycetophagidae. The list of Turkish saproxylic beetles was prepared using the European Red List of Saproxylic Beetles. Information is provided about the IUCN Red List category in Europe, the locations of the species in Turkey, and their global geographic range. We gathered all data about these species from the international literature. Furthermore, we also include in the list certain species whose locations are not specified, but which inhabit Turkey. We obtained their records from some catalogs in Turkey. In addition to the list, we prepared three distribution maps for Turkey. The maps show distribution in Turkey of some species in the Endangered, Vulnerable and Near Threatened categories in the European Red List. It is expected that this study will lead to comprehensive studies on saproxylic beetles from Turkey.     

A critical note on ‘exclusive recognition’

Cenk Saracoglu conceptualizes the antipathy towards Kurdish migrants manifesting in certain cities of Turkey since the early 2000s as ‘exclusive recognition’ in his article ‘“Exclusive recognition”: the new dimensions of the question of ethnicity and nationalism in Turkey’ published in Ethnic and Racial Studies 32(4). According to the author, these recent developments represent ‘a historically specific ethnicization process’ and its sources cannot be found directly and only in historical discourses and policy of mainstream Turkish nationalism. In this note, I contradict the author's claims by asserting that the recent manifestations of anti-Kurdish sentiments are an extension of the ongoing policies of Turkish national identity based on Turkish nationalism.     

Linguistic capital: Language as a socio-economic resource among Kurdish and Arabic women in Turkey

Data from the 1998 Turkish Demographic and Health Survey are used to gain insight into the characteristics of the non-Turkish speaking individuals in Turkey and in the socio-economic consequences of not speaking Turkish for them. The very large majority of non-Turkish speaking individuals turn out to be Kurdish and Arabic women, living in East Turkey and in the countryside. The data indicate that of the married women aged 15–49 in Turkey, about 4 per cent, or one in 25, is not able to speak Turkish. More than 90 per cent of these women has not finished primary education. Regarding their social background, our results suggest that they were more under the influence of traditional cultural values, that their access to the public domain was limited, and that they were more heavily controlled by their family. Regarding the consequences of not speaking Turkish, we found the non-Turkish speaking women to be less employed in the formal economy, to have husbands with lower educational levels and occupations and to have lower family incomes. This result is in line with the predictions of linguistic capital theory.     

Cardiolinka bohemica (Barrande, 1881) – A first representative of the Late Silurian Bohemian type Bivalvia fauna from the northern Arabian Plate,Southeast Turkey

The Rheic Ocean was a major oceanic domain between Baltica, Laurentia, Perunica and Gondwana in Ordovician-Silurian times. The cosmopolitan nepiomorphian bivalves Praecardioidei Newell, 1965 and Antipleuroidei Kříž, 2007 are characteristic of the Silurian of Perunica, peri-Gondwana, and Baltica, and occur also in Laurentia and Siberia. The Bohemian-type bivalve Cardiolinka Kříž, 1981 (Nepiomorphia Kříž, 2007, Cardiolidae Hoernes, 1884), from the Late Silurian of the Bahar-1 well core, has been found for the first time in southeastern Turkey. The strata containing the species Cardiolinka bohemica (Barrande, 1881) occur in the middle part of the Dadaş Formation in the interior Petroleum District X-Siirt of the northern parts of the Arabian Plate. The cosmopolitan species C. bohemica was until now known from the Latest Ludlow to Pridoli of the Prague Basin, France, Carnic Alps, Sardinia, East European Platform (Poland), eastern Serbia, Moesian Platform, and Arctic Canada. The new surprising subsurface data on C. bohemica in Diyarbakır-Bismil area (southeastern Turkey) therefore represent another piece of evidence in favour of strong faunistic affinity between Perunica, peri-Gondwanan Europe and the northern Gondwana margin.     

Comorbidity and continuity of attention deficit hyperactivity disorder (ADHD) from childhood to adolescence in Turkey

The aim of this study was to examine clinical outcomes, psychiatric comorbidity and neuropsychological characteristics in Turkish adolescents with an attention deficit hyperactivity disorder (ADHD) diagnosis in childhood. A total of 45 children with ADHD diagnosis and 28 children with a psychiatric diagnosis other than ADHD in a 1-year cohort of 7–10-year-olds were reevaluated 6 years later using Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime version and Wechsler Intelligence Scale for Children-Revised and Stroop Test TBAG version. This study shows that the clinical outcomes and the comorbidity patterns for ADHD from childhood to adolescence in Turkey are similar to reported rates in the Western countries. In the ADHD group, 75.6 % still has impairing ADHD symptoms and 46.6 % has comorbid psychiatric disorders. The main difference is anxiety disorders being the most common comorbid disorders (37.8 %) in Turkish ADHD youth. These findings stress the high comorbidity associated with ADHD and support the importance of assessment and treatment for ADHD and comorbidities during adolescence.
