Öğe A contribution to the knowledge of hottentotta saulcyi (simon, 1880) (scorpiones: Buthidae)(2006) Karataş A.; Gharkheloo M.M.13 specimens (6 females and 7 males) of the rare and little-known scorpion Hottentotta saulcyi (Simon, 1880) were collected from Turkey, Iraq and Iran. Its morphological characteristics such as carinal and setal features are given, and these taxonomic properties were compared between the samples from western (Turkey and Iraq) and eastern (Iran) populations of H. saulcyi. Some morphological differences (e.g. trichobothrial features, morphometric measurements, carination of carapace, mesosoma, femur and patella, setation of pedipalp segments and tergites and colouration) were established between these two populations. © 2006 Taylor & Francis Group, LLC.Öğe A new record for Turkish lice fauna: Dennyus hirundinis (Linnaeus, 1761) (Mallophaga: Menoponidae).(2008) Karataş A.; Göçmen B.; Karataş A.In this study, a bird louse Dennyus hirundinis was recorded for the first time from the swift, Apus apus living in Turkey. Since so little information is available on this rare species, the new record is briefly presented here.Öğe Contribution to karyology, distribution and taxonomic status of the long-winged bat, miniopterus schreibersii (Chiroptera: Vespertilionidae), in Turkey(2004) Karataş A.; Sözen M.The distribution of the Long-winged Bat, Miniopterus schreibersii, in Turkey is described with the help of literature records and our own new records. The range extends all over the country, with populations in Thrace, the Marmara region and the western Black Sea region belonging to the nominate form, and those in the eastern Black Sea region, in Central, eastern, southern and south-eastern Anatolia to M. s. pallidus. The transition between the two subspecies occurs in a wide area extending from the Aegean region to the central Black Sea region, where intermediate forms exist. The karyotype was analysed from the western Black Sea region, and was found to be 2n= 46, FN= 52, FNa= 48, which is in conformity with the karyotype described from other parts of the distribution area of this species. © 2004 Taylor & Francis Group, LLC.Öğe Contribution to Rousettus aegyptiacus (Mammalia: Chiroptera) from Turkey(2003) Karataş A.; Yigit N.; Çolak E.; Kankiliç T.Rousettus aegyptiacus is active throughout the year in Turkey, where its morphology was studied collected from three localities in the south-west. The characteristics of the Turkish population were similar to those of the nominative subspecies. Moderate differences between the sexes were found in tibia length and total body length. The karyotype is 2n= 36, FN= 70, FNa= 66. The X chromosome is a large metacentric/submetacentric, and the Y chromosome is a dot-like acrocentric.Öğe First record of pipistrellus pygmaeus (chiroptera: Vespertilionidae) in anatolia(2005) Dietz C.; Schunger I.; Keşapli Didrickson Ö.; Karataş A.; Mayer F.According to morphological characters and mitochondrial DNA sequences, eight very small bats of the Pipistrellus pipistrellus complex captured at the Kuş Cenneti National Park in the Marmara Region of Turkey could be assigned to the recently discovered species Pipistrellus pygmaeus. This finding represents the first record of Pipistrellus pygmaeus in Anatolia and the second in Turkey. The species may be distributed much further along the Aegean coast of Anatolia. © Kasparek Verlag, Heidelberg.Öğe Identifying key biodiversity areas in Turkey: a multi-taxon approach(Taylor and Francis Ltd., 2016) Eken G.; Isfendiyaroğlu S.; Yeniyurt C.; Erkol I.L.; Karataş A.; Ataol M.Key biodiversity areas (KBAs) are sites of global importance for biodiversity conservation. Their selection is based on standard criteria applied through a bottom-up, iterative process involving local stakeholders. This article presents the results of a study that applied the KBA methodology in Turkey. The KBA method uses four criteria: (1) globally threatened species; (2) restricted-range species; (3) congregations of species that concentrate at particular sites during some stage in their life cycle; and (4) biome-restricted species assemblages. In Turkey, we applied these criteria to 10,214 species of eight taxonomic groups: plants, dragonflies, butterflies, freshwater fish, amphibians, reptiles, birds and mammals. We identified 313 KBAs in Turkey, 303 of which trigger the KBA criteria for one or more taxonomic groups at the global scale. The remaining 10 sites trigger the KBA criteria at the regional scale only. These 303 globally important KBAs in Turkey cover 20,456,884 hectares, 26% of the country. Turkey’s natural landscapes, holding globally important biodiversity, are under immense threat and declining rapidly, both in quality and quantity. The nationwide threat assessment of KBAs revealed that dams, irrigation and drainage projects (i.e. water policies) form the main threat to Turkey’s biodiversity. Irrigation and drainage projects affect 225 KBAs and dams have an effect on at least 185 sites. KBAs raise attractive possibilities as being core areas where ecologically responsible governance models can be demonstrated, building on scientific and indigenous knowledge. © 2016 Informa UK Limited, trading as Taylor & Francis Group.Öğe Karyological comparison of populations of the spalax leucodon nordmann, 1840 superspecies (rodentia: spalacidae) in turkey(2007) Kankılıç T.; Çolak R.; Çolak E.; Karataş A.; Kankılıç T.One hundred and seventy-seven specimens of Spalax leucodon Nordmann, 1840 from 41 localities in Turkey were examined for their karyologicalfeatures. Nine karyotypic forms were recorded. 2n= 50, NF= 72, NFa= 68 was recorded from Bayburt, Erzincan, Giresun, and Rize, 2n= 54, NF= 74, NFa= 70 from Kırıkkale, 2n= 52, NF= 70, NFa= 66 from Bolu, and 2n= 56, NF= 72, NFa= 68 and 2n= 60, NF= 78, NFa= 74 from Isparta. Based on an extensive literature review, it was shown that the karyotypic form 2n= 60 has the widest distribution in the subspecies cilicicus, while the form 2n= 50 has the widest distribution in the subspecies nehringi. The subspecies nehringi was also found in the area of Kırıkkale in Inner Anatolia for the first time. A map of all the karyotypes is given, based on literature data and our own results. © 2007 Taylor & Francis Group, LLC.Öğe Karyology of three bat species of the genus myotis (m. myotis, m. bechsteinii, m. brandtii) (chiroptera: vespertilionidae) from Turkey(2007) Karataş A.; Sözen M.; Matur F.; Özkurt Ş.The karyotypes of three vespertilionid bat species from Turkey were examined. The karyotypes of these species were found as 2n=44, NF=54 and NFa=50 for Myotis myotis; 2n=42, NF=50, and NFa=46 for Myotis bechsteinii; 2n=44, NF=54, and NFa=50 for Myotis brand-tii. The M. brandtii karyotype of was studied for the first time for Turkey. Further details on the karyotype of M. bechsteinii, which had been described previously, are given. © 2007 Taylor & Francis Group, LLC.Öğe Karyology of three vespertilionid bats (Chiroptera: Vespertilionidae) from Turkey(2007) Karataş A.; Sözen M.The karyotypes of three vespertilionid bat species from Turkey were examined. The karyotypes of Eptesicus serotinus and Eptesicus bottae were found to be identical in diploid number (2n) and fundamental number of chromosomal arms (NF) with 2n = 50, NF = 52 and NFa = 48. The karyotypes were found as 2n = 42, NF = 54, and NFa = 50 for Nyctalus noctula. The karyological characteristics of E. bottae anatolicus and N. noctula were studied for the first time from Turkey.Öğe Karyotypes of seven rodents from jordan (mammalia: rodentia)(2008) Sözen M.; Karataş A.; Shehab A.; Fawzi A.; Amr Z.We present here data on the karyotypes of seven species of rodents from Jordan. The karyotype of Acomys dimidiatus was found to be 2n= 38, NF= 70; Acomys russatus russatus and A. r. lewisi 2n= 66, NF= 94; Apodemus flavicollis 2n= 48, NF= 48; Apodemus mystacinus 2n= 48, NF= 52; Meriones tristrami 2n= 72, NF= 76; Skeetamys calurus 2n= 38, NF= 70; Allactaga euphratica 2n= 48, NF= 96. Of these species, the karyotypes of A. flavicollis, A. mystacinus, S. calurus, and A. euphratica are here reported for the first time from Jordan. © 2008 Taylor & Francis Group, LLC.Öğe Karyotypes of two Iranian bat species, myotis blythii and miniopterus schreibersii (Chiroptera: Vespertilionidae, Miniopteridae)(2008) Karataş A.; Gharakheloo M.M.; Kankiliç T.The karyotypes of 2 bat species from Iran were examined. The diploid number of chromosomes (2n) and the fundamental numbers of chromosomal arms (NFa) were determined to be 2n = 44 and NFa = 54 for Myotis blythii and 2n = 46 and NFa = 50 for Miniopterus schreibersii, respectively. The karyotypes of Iranian bats show similarity within populations in other countries with respect to the diploid chromosome numbers: however, they are quite different in the fundamental chromosome numbers and the numbers of autosomal arms. © Tübi·tak.Öğe Note: Karyotype of Taphozous nudiventris cretzschmar, 1830 (Mammalia: Chiroptera) from Turkey(2002) Karataş A.; Sözen M.[No abstract available]Öğe Notes on the mammals found in Kazdagi National Park and its environs(2006) Yigit N.; Karataş A.; Demirsoy A.; Özkurt Ş.; Çolak E.The present study is based on species collected and observed in Kazdagi National Park and its surroundings. Field collections yielded 40 mammal species from 6 orders: Insectivora (4), Chiroptera (14), Lagomorpha (1), Rodentia (11), Carnivora (8), and Artiodactyla (2). Of the species recorded in this study, 6 were new records from north-west Anatolia: Sorex volnuchini, Rhinolophus hipposideros, Myotis emarginatus, Eptesicus serotinus, Hypsugo savii, and Microtus subterraneus. © TÜBİTAK.Öğe On the occurrence of geoffroy’s bat, myotis emarginatus (geoffroy, 1806), in turkey (chiroptera: vespertilionidae)(2003) Karataş A.; Özgül S.A.Myotis emarginatus was collected at eleven new localities in southern Turkey and Turkish Thrace, and specimens were examined from morphological and biometric points of view. Comparison of these characteristics with literature data revealed that the Turkish population belongs to the nominate subspecies. The distribution area extends mainly along the coastal zones of Turkey. © 2003 Taylor & Francis Group, LLC.Öğe Phylogeography of the Mediterranean horseshoe bat, Rhinolophus euryale (Chiroptera: Rhinolophidae), in southeastern Europe and Anatolia(2008) Bilgin R.; Furman A.; Çoraman E.; Karataş A.The mitochondrial genetic differentiation of the Mediterranean horseshoe bat, Rhinolophus euryale Blasius, 1853, was investigated in southeastern Europe and Anatolia. Mitochondrial DNA tRNA-proline and control region sequences were used for the analyses. As a result of the phylogenetic analyses, two reciprocally monophyletic clades were found with very high support. The results suggested that secondary contact after allopatric differentiation in separate glacial refugia, and subsequent range expansion was the best explanation regarding the evolutionary history of this species in the region. The geographical distribution of the haplotypes also suggested that the Balkans and the Black Sea could be representing refugia from which the region was populated. There also was evidence for population expansion following a pattern of isolation by distance, with geographically more distant samples also being genetically more differentiated. © Museum and Institute of Zoology PAS.Öğe Some karyological records and a new chromosomal form for Spalax (Mammalia: Rodentia) in Turkey(2006) Sözen M.; Matur F.; Çolak E.; Özkurt Ş.; Karataş A.The karyotypes of 73 specimens of subterranean mole rats of the superspecies Spalax leucodon Nordmann, 1840 from 21 localities, and six specimens of the superspecies Spalax ehrenbergi Nehring, 1898 from three localities in Turkey were analysed. S. leucodon has 2n = 56, NF = 78 in the populations from Thrace; and 2n = 48, NF = 71; 2n = 50, NF = 70; 2n = 50, NF = 72; 2n = 54, NF = 75; 2n = 56, NF = 72; 2n = 58, NF = 72; 2n = 60, NF = 74; 2n = 60, NF = 76; 2n =60, NF = 77 in the populations from Anatolia. S. ehrenbergi has 2n = 56, NF = 72 in the Adana population, and 2n =52, NF = 74 in the Elbeyli population. According to these karyological findings based on chromosome morphology, the diploid chromosome number of 2n = 48, NF = 71 reported here is new for Spalax leucodon in Turkey. The karyological peculiarities and distributional area of mole rats in the European part of Turkey have been determined in detail, and shown that only the 2n = 56 form is distributed in Thrace.Öğe Spinturnix acuminata (C. L. Koch, 1836), a species new to the fauna of Turkey (Acari, Mesostigmata)(2004) Karataş A.; Çakır M.[No abstract available]Öğe The bat fauna of the caves near havran in western turkey and their importance for bat conservation(2005) Rudolph B.-U.; Liegl A.; Karataş A.This paper describes the bat fauna of a cave system with three caves in a karst area near Havran in Western Turkey. One of these caves harbours approximately 15–20,000 adult bats of eight species, all of them forming nursery colonies. This represents the second largest summer colony of bats in Turkey. The species richness and the colony sizes qualify the site as an Important Mammal Area and would qualify it as a Special Area for Conservation, according to the Habitats Directive of the European Union. The area including the most important bat cave will be partly flooded by a dam which is currently being constructed by the State Water Authority. © 2005 Taylor & Francis Group, LLC.Öğe The karyotypic characterisation of the large horseshoe bat, rhinolophus ferrumequinum (schreber, 1774) (chiroptera: Rhinolophidae) from iran(2006) Karataş A.; Gharkheloo M.M.; Gharkheloo M.R.The diploid number of chromosomes of the karyotype of the Large Horseshoe Bat, Rhinolophus ferrumequinum from West Azerbaijan, Iran, is 2n=58, the fundamental number of chromosomes NF=62, and the number of chromosomal arms NFa=58. The Iranian karyotype thus shows similarity to different populations in neighbouring countries as regards the diploid chromosome number, but it is quite different in the fundamental chromosome number and the number of autosomal arms. © 2006 Taylor & Francis Group, LLC.
