Ege denizi ve Marmara denizi’ndeki adalardan Türkiye kemirici faunasının karyolojisine ve yayılışına katkılar
No full textA chromosomal study on five different rodent species (Mus domesticus, Mus macedonicus, Apodemus sylvaticus, Apodemus witherbyi and Rattus rattus) from Gökçeada and Bozcaada in Aegean Sea and Marmara Island in Marmara Sea was performed to fill the deficiency of karyological information about island populations of these species. Diploid chromosome sets (2n) and fundamental numbers of chromosomal arms (NF) were determined to be 2n = 40, 40, 48, 48 and 38, NF = 40, 40, 48, 48 and 60 for M. domesticus, M. macedonicus, A. sylvaticus, A. witherbyi and R. rattus respectively. Results showed that there was no difference between karyological values in island and continental populations of those rodents, although Aegean and Marmara seas have served as geographic barriers for a long time between islands and mainland. In addition to the karyotypes of M. domesticus, M. macedonicus, A. sylvaticus and R. rattus, their presence in Marmara Islands were firstly determined by current studyBeş farklı kemirici türünün (Mus domesticus, Mus macedonicus, Apodemus sylvaticus, Apodemus witherbyi ve Rattus rattus) Türkiye’deki ada populasyonlarına ilişkin karyolojik bilgi eksikliğini gidermek amacıyla, bu türlerin Ege Denizi’nde yer alan Gökçeada ve Bozcaada ile Marmara Denizi’nde yer alan Marmara Adası’nda yayılış gösteren populasyonları üzerine kromozomal bir çalışma gerçekleştirilmiştir. M. domesticus, M. macedonicus, A. sylvaticus, A. witherbyi ve R. rattus için diploit kromozom sayıları ve temel kromozom kol sayıları sırasıyla 2n = 40, 40, 48, 48 ve 38, NF = 40, 40, 48, 48 ve 60 olarak belirlenmiştir. Ege Denizi ve Marmara Denizi bu türlerin adalarda ve anakarada yayılış gösteren populasyonları arasında gen akışının kesilmesine neden olan coğrafik bariyerler olarak uzun süredir görev yapmaktadır, buna rağmen, bu çalışma ile bu kemirici türlerinin adalarda ve anakarada yayılış gösteren populasyonları arasında karyolojik bakımdan herhangi bir farklılaşma olmadığı tespit edilmiştir. Ayrıca, M. domesticus, M. macedonicus, A. sylvaticus ve R. rattus’un Marmara Adası’nda yayılış gösterdiği ilk kez bu çalışma ile belirlenmişti
Georeferenced vascular plant collections in south Tuscany (Italy)
No full textThe dataset refers to 4535 selected floristic collections mainly done by the first author in southern Tuscany (Maremma, Italy) during the last 35 years (1989-2024, Herbarium F. Selvi). The collections are largely unpublished and currently kept in the Herbarium Centrale Italicum at the Natural History Museum of Florence University (FI, H.C.I.). The collections belong to 1766 specific and subspecific taxa with updated names according to the Portal to the Flora of Italy, in 122 families of vascular plants. Each record is associated with textual information on the collection locality, date, collector(s), number and geographical coordinates in the WGS84 system. Many collections were made in floristically poorly known parts of the region and mostly in the province of Grosseto, documenting new sites of several uncommon or phytogeographically relevant taxa. The information dataset allows to deepen the botanical knowedge of Tuscany and central Italy
Determination of genetic variations in the genus Dryomys Thomas, 1906 (Rodentia: Gliridae) distributed in Turkey using NADH dehydrogenase 1 (ND1) gene
No full textWOS: 000439832300013PubMed: 29072519Genetic diversity and phylogeny of Dryomys nitedula and Dryomys laniger from Turkey was described in the present study by using mitochondrial DNA NADH dehydrogenase 1 gene (ND1). Genetic variation in ND1 gene was determined by two model-based phylogenetic analyses and a network analysis revealed 27 haplotypes of D. nitedula constructing four main lineages (Thrace, Anatolia, North-eastern Anatolia and Savsat) that have non-overlapping geographic distributions and no shared haplotypes, but on the other hand, three haplotypes were detected in four samples of D. laniger from Turkey. It was determined that nucleotide diversity was low but haplotype diversity was high in D. laniger, whereas, D. nitedula has both high level of haplotype and nucleotide diversity. Characterization of Thrace lineage of D. nitedula with low nucleotide diversity and determination of the total nucleotide diversity of Anatolian lineages (Anatolia + North-eastern Anatolia + Savsat) to be approximately four times higher than that of Thrace lineage indicated that Anatolia may have served as a refuge for D. nitedula. Divergence times and high level of nucleotide differences between D. nitedula lineages showed that diversification of the lineages may have occurred before and during ice ages in Turkey, thought to be a refuge for post-glacial colonization and biodiversity resource of Europe. Additionally, estimated divergence times and calculated genetic distances yielded compatible results with the previous paleontological and genomic data for the diversification time of two species in the genus.Scientific Research Projects Coordination Unit of Nigde Omer Halisdemir University [YULTEP FEB 2015/06]; Scientific and Technological Research Council of Turkey (TUBITAK) [113Z822]This study was supported by Scientific Research Projects Coordination Unit of Nigde Omer Halisdemir University [grant number: YULTEP FEB 2015/06] and The Scientific and Technological Research Council of Turkey (TUBITAK) [grant number: 113Z822]
Garrigue plant communities of ultramafic outcrops of Tuscany (central Italy)
No full textGarrigue plant communities of the ultramafic outcrops in Tuscany are here analyzed from a phytosociological point of view on the basis of original and published data. All the investigated vegetation types belong to the association Armerio-Alyssetum bertolonii, already described from Monte Ferrato. Two subassociations, typicum and Euphorbietosum spinosae subass. nova, are recognized, their distribution evidenced and their structural and chorological differences pointed out. The syntaxonomical problems of the Tuscan ultramafic communities are discussed. -Author
Thirty-five years of floristic collections in southern Tuscany (Italy)
No full textFloristic knowledge and georeferenced information about vascular plant species distribution in southern Tuscany (Italy) are still poor for supporting effective biodiversity conservation efforts.A dataset of georeferenced floristic collections from Southern Tuscany, which was developed by the first author between 1989 and 2024, is provided and briefly commented on. The dataset includes data for 4535 herbarium specimens, mostly unpublished, currently preserved in the Herbarium Centrale Italicum at the Natural History Museum of Florence (FI). The specimens belong to 1766 species and subspecies in 122 families of vascular plants. Each record is associated with a Unique Identifier (UID) and information on the collection locality, date, collector(s), and geographical coordinates (WGS84 geodetic datum). Many specimens were collected in areas that were poorly investigated, documenting new sites for several uncommon or phytogeographically relevant taxa. The dataset includes two specimens of Euphorbia meuselii Geltman, a forest herb endemic to Southern Italy and new to the flora of Tuscany. Overall, this dataset allows a relevant advancement in the floristic knowledge of central Italy
Mitochondrial DNA (Cytochrome b and control region) analysis of Apodemus species Kaup, 1829 (Mammalia:Rodentia) in North Anatolia and Thrace
No full textBu tez çalışmasında Türkiye'nin kuzeyinde, Trakya'da ve yüz ölçümü bakımından sırasıyla Türkiye'nin üç büyük adası olan Gökçeada, Marmara Adası ile Bozcaada'da yayılış gösteren Apodemus cinsine dahil örneklerin mitokondriyal DNA'sının sitokrom b ve kontrol bölgesindeki varyasyonlar araştırıldı. DNA dizi analizi sonucunda elde edilen bulgular bu tezin kapsamındaki çalışma alanında Apodemus cinsinin 6 türünün (Apodemus flavicollis, Apodemus mystacinus, Apodemus witherbyi, Apodemus uralensis, Apodemus sylvaticus ve Apodemus agrarius) yayılış gösterdiğini ortaya çıkardı. A. flavicollis'in Trakya ve Anadolu populasyonlarının iki farklı genetik soy hattı oluşturduğu belirlendi. A. mystacinus populasyonları Batı Karadeniz ve Orta/Doğu Karadeniz olmak üzere iki farklı genetik gruba ayrıldı. Bu güne kadar Türkiye'de sadece Anadolu'nun büyük bölümünde yayılış gösterdiği bilinen A. witherbyi populasyonlarının Trakya'da yayılışının olduğu ilk kez bu çalışma ile tespit edildi. A. uralensis populasyonları arasında gen akışının devam ettiği, dolayısıyla genetik farklılaşmanın az olduğu sonucuna varıldı. Parçalı yayılışa sahip olan A. sylvaticus'un Anadolu'dan tek bir lokalitedeki Kurupelit (Samsun) populasyonu ile Gökçeada, Marmara adası ve Trakya populasyonları arasında yüksek genetik farklılıkların bulunduğu açığa çıkarıldı. Trakya'da yayılışı olan A. agrarius'un sadece bir lokaliteden incelenen populasyonunda haplotip çeşitliliğinin yüksek, nükleotid çeşitliliğinin düşük seviyede olduğu bulundu. Miyosen, Pliyosen ve Pleyistosen dönemlerinde meydana gelen jeolojik, tektonik olaylarla beraber iklim değişikliklerinin Apodemus cinsi türlerinin genetik farkılılaşması üzerinde etkili olduğu ortaya kondu.In this thesis, variations in cytochrome b and control region of mitochondrial DNA in the samples of the genus Apodemus distributed in northern Turkey, Thrace and three islands in Turkey (Imbros, Marmara Island and Tenedos, which are the biggest islands of Turkey according to the their surface areas, respectively) were investigated. The findings provided by DNA sequence analysis revealed that 6 species of Apodemus (Apodemus flavicollis, Apodemus mystacinus, Apodemus witherbyi, Apodemus uralensis, Apodemus sylvaticus and Apodemus agrarius) live in the study area of this thesis. It was determined that Thrace and Anatolia populations of Apodemus flavicollis formed two different genetic lineages. Apodemus mystacinus populations were divided into two different genetic groups (Western Black Sea and Central/Eastern Black Sea). So far, A. witherbyi populations, which has been known to be lived in the most parts of Anatolia, were recorded from Thrace for the first time by this thesis. A continuing gene flow and therefore little genetic differentiation between A. uralensis populations were determined. It was deduced that there was high genetic differentiation between Kurupelit (Samsun) population and populations from Imbros, Marmara Island and Tenedos of A. sylvaticus distributed in fragmented habitats. It was found that one population of A. agrarius from only one locality in Thrace had high haplotype diversity, but, low nucleotide diversity. It was determined that geologic, tectonic events as well as climatic oscillations occurred during Miocene, Pliocene and Pleistocene had an impact on the genetic differentiation of Apodemus species
THE EFFECTS OF KITSCH CONCEPT ON THE AESTHETIC PERCEPTION AND TASTE OF HIGH SCHOOL STUDENTS
No full textBu araştırmada, Ankara ili merkezinde yaşayan ve farklı liselerde okuyan
öğrencilerin estetik algı ve beğenilerinin, kitsch olgusundan etkilenme düzeyleri ve
öğrencilerin kitsch ürünleri benimsemelerinin altında yatan faktörler
belirlenmektedir.
Her geçen gün kültürün yozlaşması ve popüler kültürün hızla yayılması ile
ortaya çıkan kitsch olgusu ve ürünleri toplumun her kesiminden insanları ve
dolayısıyla eğitim sistemimizdeki öğrencilerimizi olumsuz yönde etkilemektedir.
Araştırmada; öğrencilerin estetik algı ve beğeni gelişimlerinin, kültür endüstrisinin
ideolojisi doğrultusunda ticari amaçlarla üretilen, kitsch ürünler tarafından
etkilenmesindeki nedenlerin ortaya konulması ve öğrencilerin bu olumsuz etkilerden
kendilerini nasıl koruyabilecekleri sorusuna yanıtlar bulunması amaçlanmıştır.
Çünkü öğrencilerimizin, hiçbir sanatsal değeri olmayan ve tamamen ticari kaygılarla
sisteminin işleyişine ve devamlılığına hizmet etmesi için üretilen aldatıcı ve ikiyüzlü
yoz sanatı benimseyip etkilenmeleri, geleceğimizi oluşturacak olan toplumun
yapısını ve sağlığını olumsuz yönde etkileyecektir.
Elde edilen bulgulara göre, öğrenimlerine devam eden lise öğrencilerinin
ailelerinin eğitim düzeylerinin; öğrencilerin kitap okuma alışkanlıklarını, televizyon
izleme alışkanlıklarını, sanata olan ilgilerini ve kitsch ürünleri benimsemelerini
etkilediği görülmüştür.
Araştırma sonunda, ortaya çıkan sorunlara dayalı olarak araştırmacı
tarafından ortaya konulan önerilere yer verilmektedir.

This study aims to find out the degree of the influence of kitsch concept on the
taste and aesthetic perception of students who live and study in different high schools
in the centre of Ankara and the reasons why students adopt the products of kitsch.
Day by day, because of the development of cultural degeneration and the high
spread of popular culture, the concept of kitsch and its products affect not only
people from different classes of society but also our students in the education
system.This study aims to explain the students' aesthetic perception and taste
development, kitch products which are produced by the ideology of culture industry
and also aims to find out the answers of the questions why students are influenced
by the kitch products and how they can protect themselves from these negative
effects. Because; if our students adopt or if they are influenced by the degenerated,
deceiving work of art which has no artistic value and which has been produced with
financial worries to serve the continuation of the system, the development and
structure of our future society and new generation will be influenced negatively.
After the analysis of the results, it is seen that the education level of the
families of the students who are studying in high schools effects students habits of
reading books, watching TV, interest in arts and adoption of kitsch products.
In the conclusion part of the study, suggestions of the researcher take place
which are based on the problems mentioned
