Öğe An extremely low genetic divergence across the range of Euscorpius italicus (Scorpiones, Euscorphdae)(AMER ARACHNOLOGICAL SOC, 2006) Fet, Victor; Gantenbein, Benjamin; Karatas, Aysegul; Karatas, AhmetLittle or no genetic divergence is detected using mitochondrial 16S rDNA sequence comparisons across the entire geographic range of the scorpion Euscorpius italicus (Herbst 1800) from Switzerland, Italy, Slovenia, Greece and Turkey. This is consistent with known absence of patterns of allozymes and morphological variation. Euscorpius italicus is found almost exclusively in human habitations. Its sister species, E. naupliensis, exhibits much higher genetic diversity within southern Greece. We suggest that the natural populations of the thermophilic E. italicus underwent a bottleneck during the glaciations, and that its modem range could be a result of dispersal with humans.Öğe Camera trap records confirm the survival of the Leopard (Panthera pardus L., 1758) in eastern Turkey (Mammalia: Felidae)(Taylor & Francis Ltd, 2021) Karatas, Ahmet; Bulut, Safak; Akbaba, BurakThe Leopard, Panthera pardus, was thought to be extinct or on the verge of extinction in Turkey towards the end of the 20(th) century. However, as leopards killed by local people were reported from the Turkish-Iraqi border area in the last two decades, we carried out field surveys in these regions in order to find out whether the species has survived. We set camera traps at more than 150 locations in Mardin, Siirt and Sirnak provinces in south-eastern Turkey in 2018 and 2019 and succeeded in obtaining altogether three pictures of leopards, probably of the same individual. The photographs, taken in July and December 2018, and in November 2019, are from two different sites on the northern slopes of Mount Cudi. Together with previous records, these observations indicate that a small population of the leopard has survived in the Turkish-Iraqi border area. Cudi Mountain may serve as a corridor for leopards moving between Turkey, Iraq and Iran. Our records comprise the first photographic evidence of living leopards in Turkey in the wild.Öğe Census and spatial distribution of White Stork (Ciconia ciconia) population in Kosovo in 2017 and 2018(Walter De Gruyter Gmbh, 2023) Maxhuni, Qenan; Karatas, Ahmet; Fiedler, WolfgangIn this study, during 2017-2018, for the first time in Kosovo, research on the census, distribution and population dynamics of the White Stork was made. 61 new nests were found in the whole country territory and together with 22 known nests, the total population is recorded to 83 nests and 72 breeding pairs. In total, 461 chicks were raised in the successful nests. Breeding success for the country territory during the observation period of all breeding pairs was 3.18, and 3.19 of all breeding pairs that raised chicks. The mean breeding density for the entire country was 0.67 breeding pairs/100 km(2) in 2017 and 0.70 in 2018. For the potential feeding habitats, it was 2.19 (2017) and 2.28 (2018). The densest area, the river basin of Lepenci held 2.48 pairs for 100 km(2). 48.61% of all recorded White Stork nests were located on various poles.Öğe Characterization of Bartonella taylorii Strains in Small Mammals of the Turkish Thrace(Springer, 2020) Polat, Ceylan; Celebi, Bekir; Irmak, Sercan; Karatas, Ahmet; Colak, Faruk; Matur, Ferhat; Sozen, MustafaRodents play role as a reservoir for some Bartonella species which cause different clinical manifestations in humans. Bartonella spp. existence in rodents of Turkish Thrace has been detected for the first time, and the risky habitat types were evaluated for the infection. Ninety individuals belonging to three small rodent species were screened by PCR, and the overall prevalence of Bartonella infection was 22.2%. The strains were characterized molecularly based on the phylogenetic analyses of two housekeeping genes, rpoB and gltA. They clustered with B. taylorii. The significant effects of habitat types and rodent species on Bartonella infections were observed. It was detected that B. taylorii prevalence was the highest in the swamp forest habitat and A. flavicollis species. The present study demonstrates that A. flavicollis is the reservoir of B. taylorii in the European part of Turkey.Öğe Circum-Mediterranean phylogeography of a bat coupled with past environmental niche modeling: A new paradigm for the recolonization of Europe?(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2016) Bilgin, Rasit; Gurun, Kanat; Rebelo, Hugo; Puechmaille, Sebastien J.; Maraci, Oncu; Presetnik, Primoz; Karatas, AhmetThe isolation of populations in the Iberian, Italian and Balkan peninsulas during the ice ages define four main paradigms that explain much of the known distribution of intraspecific genetic diversity in Europe. In this study we investigated the phylogeography of a wide-spread bat species, the bent-winged bat, Miniopterus schreibersii around the Mediterranean basin and in the Caucasus. Environmental Niche Modeling (ENM) analysis was applied to predict both the current distribution of the species and its distribution during the last glacial maximum (LGM). The combination of genetics and ENM results suggest that the populations of M. schreibersii in Europe, the Caucasus and Anatolia went extinct during the LGM, and the refugium for the species was a relatively small area to the east of the Levantine Sea, corresponding to the Mediterranean coasts of present-day Syria, Lebanon, Israel, and northeastern and northwestern Egypt. Subsequently the species first repopulated Anatolia, diversified there, and afterwards expanded into the Caucasus, continental Europe and North Africa after the end of the LGM. The fossil record in Iberia and the ENM results indicate continuous presence of Miniopterus in this peninsula that most probably was related to the Maghrebian lineage during the LGM, which did not persist afterwards. Using our results combined with similar findings in previous studies, we propose a new paradigm explaining the general distribution of genetic diversity in Europe involving the recolonization of the continent, with the main contribution from refugial populations in Anatolia and the Middle East. The study shows how genetics and ENM approaches can complement each other in providing a more detailed picture of intraspecific evolution. (C) 2016 Elsevier Inc.

The dorsal fur of the Greater Noctule, which also covers the underpart of the wing membrane, along with the forearm and propatagium, is uniformly dark brown. The cranium shows typical characteristics of the noctule bats. In addition to these, the exoccipital is convex and is markedly visible in the planar view of the skull. There is a small depression mid braincase. The dental formula is i: 2, c: 1, pm: 1, m: 3/i: 3, c: 1, pm: 2, m: 3 = 32. The diploid number of chromosomes and the number of chromosomal arms are 2n = 42 and FN = 54, respectively.Öğe Contributions on the southern distribution of Vespertilio murinus Linnaeus, 1758 (Chiroptera: Vespertilionidae) from Turkiye(Tubitak Scientific & Technological Research Council Turkey, 2022) Karatas, Ahmet; Bulut, Safak; Sefali, Abdurrahman; Toprak, Ferhat; Sahin, Mehmet Kursat; Ozkurt, Sakir OnderVespertilio murinus Linnaeus, 1758, has a wide distribution from France to Japan, and from Iran in the south to Scandinavia and Russia in the north. The only records of the parti-coloured bat, Vespertilio murinus known from Turkey so far were based on subfossils, remains from owl pellets, and ultrasound recordings. We present the first records of live individuals from two Turkish provinces, Ardahan and Bayburt. Additionally, based on echolocation call records, its known distribution in the Anatolian Peninsula was proved to be wider. The global distribution of the species has been mapped by using ecological niche modelling. The results revealed that its distribution is highly influenced by precipitation dynamics. Although no cases of domestic cat predation on bats have previously been documented in Turkey, this paper also provides the first case study of V. murinus predated by a domestic cat in Ardahan, in November 2003.Öğe Description of the male of Gluviopsis paphlagoniae Turk, 1960 (Solifugae: Daesiidae) from Turkey(Magnolia Press, 2021) Karatas, Aysegul; Ucak, Munir; Karatas, Ahmet; Ozbay, Mustafa Kemal[Abstract Not Available]Öğe Distribution and activity period of the invasive Orosanga japonica (Melichar, 1898) (Hemiptera: Ricaniidae) in Turkey(Taylor & Francis Ltd, 2020) Karatas, Ahmet; Karatas, Aysegul; Yavuz, Nizamettin; Genc, MuratThe invasive speciesOrosanga japonicawas found at 38 sites in Black Sea coastal zone of Turkey. It was recorded for the first time from the Central Black Sea Region, and for the second time from Western Black Sea Region and in the European part of Turkey. Most localities were close to the Black Sea (<3 km) and situated at altitudes lower than 150 m a.s.l. with the highest records up to 500 m a.s.l. Maximum distance from the sea was in Alemdag, with c. 15 km, and Erenkoy, with c. 10 km. This species is confined in Turkey to the high-rainy and humid coastal zones. Additionally considering cultivated plants,O. japonicawas found on 18 host plant species, of which 15 were previously not known to be used by the species. Nymphs of this univoltine pest were found between May and July, depending on the weather conditions such as rainfall and temperature. Adults emerged between early June and mid-September, with the highest density in the second half of August. Eggs were observed from late August to mid-June.Öğe Dobrava hantavirus variants found in Apodemus flavicollis mice in Krklareli Province, Turkey(Wiley, 2018) Polat, Ceylan; Sironen, Tarja; Plyusnina, Angelina; Karatas, Ahmet; Sozen, Mustafa; Matur, Ferhat; Vapalahti, OlliHantaviruses infect humans via inhalation of viral particles within secretions of infected rodents or rarely through direct contact with infected rodents. Determining the prevalence of hantavirus infections among rodent populations is of vital importance to obtain information on hantavirus-related cases and to predict possible outbreaks. We hypothesized that DOBV strains circulating in the Thrace Region in Turkey would be related to other Balkan DOBV strains. In this study, hantavirus infections in the rodent population of the Krklareli-neada Region (north-western Turkey, near the Bulgarian border) were investigated. This region is of particular importance, as it is located in the south-eastern margin of the European continent and was used as an entrance point of Asian faunal elements into Europe. DOBV infection was detected in eight of 73 rodents; all were of the Apodemus flavicollis species. Partial sequences of the viral S-, M-, and L-genome segments were recovered and compared with previously reported DOBV sequences. The newly characterized Turkish strains were similar to other DOBV variants. Silent nucleotide mutations were dominant. The hantavirus prevalence in the neada region was similar to what has been reported in Greece and Bulgaria. For the first time, the M-segment sequences of DOBV from Turkey were recovered and genetic data of hantaviruses from Thrace region of Turkey were obtained.Öğe Does Argya altirostris (Hartert, 1909) (Passeriformes: Leiothrichidae) extend its distribution to northern Anatolia?(Univ Oradea Publ House, 2023) Karatas, Ahmet; Unal, Meltem; Cicek, KerimThe Iraq Babbler, Argya altirostris (Hartert, 1909), previously known only along the Euphrates and Tigris rivers in Iraq, Syria, and western Iran, was discovered in Turkiye at the end of the 1990s. It was observed only along the Euphrates Valley between Nizip (Gaziantep) and Birecik (Sanliurfa) for more than 15 years. Recently, it was seen in some other parts of Gaziantep and Sanliurfa provinces as well as Adiyaman, Hatay, Kahramanmaras, Mersin, and Osmaniye in south Turkiye. The species was found in a few localities of Adiyaman (Golbasi), Hatay (Kirikhan, Hassa, Samandag), and Mersin (Silifke) provinces between 2020-2022 in the western and northern direction of its distribution. The six new district records are reported here for the first time. Thus, its distribution has extended to the Mediterranean and the western Turkiye (Anatolia) in the northernmost area of the species' range. Similarly, its distribution in Karbala Province expanded westwards concerning our new locality record from Iraq. To test its expansion in northern and southern Anatolia, we performed species distribution modeling for four time periods, as simulated in five General Circulation Models (GCMs), to evaluate the distributional shifts of the Iraq Babbler over the decades and to forecast its future projections. The results show that the Iraq Babbler could expand its distribution in the Mediterranean and western Turkiye and confirm our field observations. The currently unsuitable areas could become suitable by 2100, most likely expanding its potential habitat in Turkiye.Öğe Food and feeding habits of some bats from Turkey(MUSEUM & INST ZOOLOGY PAS-POLISH ACAD SCIENCES, 2009) Whitaker, John O., Jr.; Karatas, AhmetFood habits data were obtained from 26 species of bats from Turkey. Barbastella barbastellus, Myotis capaccinu, M mystacinus Plecotus auritus, P austriacus, P kolombatovici, P macrobullaris, and Rhinolophus euryale were primarily moth feeders. Epstesicus bottae, E serotinus, Myotis myotis, and Taphozous nudiventris fed heavily on beetles. Myotis aurascens and, M brandtu fed heavily on Diptera Myotis blythu and Tadarida teniotis were tentatively classified as cricket feeders at least in Turkey Hypsugo savu, Minitopterus schreibersu, Myotis emarginatus, M nattereri, Pipistrellus kuhlu, P pipistrellus, P pygmaeus, Rhinolophus ferrumequinum R hipposideros, and R mehelyi preyed on a variety of insects and may be treated as generalists. In 17 species, the foods found paralleled those previously reported in the literature, but in nine (some with notably small samples) they did not. These are apparently the first data on the food of Plecotus macrobullaris, P kolombatovict, M schreibersii, and M aurascens.Öğe Hard pellets from bats of Turkey(MUSEUM & INST ZOOLOGY PAS-POLISH ACAD SCIENCES, 2010) Whitaker, John O., Jr.; Karatas, Ahmet[Abstract Not Available]Öğe Insecta non gratae: New Distribution Records of Eight Alien Bug (Hemiptera) Species in Turkey with Contributions of Citizen Science(Magnolia Press, 2021) Cerci, Baris; Karatas, Ahmet; Karatas, AysegulThis study is prepared to provide an example for the utility of citizen science in faunistic research, which is becoming popular as a data source, especially for invasive alien species. With the globalization tendency of many living species by human impact, alien species rapidly spread far from their natural distribution range and become invasive in their newly settled ecosystems. Some of these invasive alien species become one of the most important problems for nature. This study focuses on distribution of following eight alien Hemiptera species that have previously been recorded from Turkey: Zelus renardii (Reduviidae), Corythucha arcuata and Corythucha ciliata (Tingidae), Leptoglossus occidentalis (Coreidae), Perillus bioculatus and Halyomorpha halys (Pentatomidae), Stictocephala bisonia (Membracidae) and Metcalfa pruinosa (Flatidae). New distributional and seasonality data for all these species are presented based on observations shared by citizen scientists in the websites Dogalhayat and iNaturalist. New provincial records for each species are given. As a result, it is apparent that citizen science is an important data source, supplies remarkable contribution for increasing the understanding on expansion of invasive alien species as well as providing clear picture on their distribution.Öğe Insectum non grata: the harlequin ladybird, Harmonia axyridis (Pallas, 1773) (Coleoptera, Coccinellidae) in Turkey(Tubitak Scientific & Technological Research Council Turkey, 2021) Karatas, Ahmet; Karatas, Aysegul; Yavuz, Nizamettin; Ulker, Elif Deniz; Kocak, Ozgur; Akbaba, BurakThe Harlequin Ladybird, Harmonia axyridis (Pallas, 1773), is native to Eastern Asia but it has been introduced to many countries in Africa, America, and Eurasia. In Turkey, H. axyridis is one of the most fast-spreading invasive alien species. Since the collection of the first specimens in 2010, H. axyridis spread almost all over the country. The species spreads fast in Turkey according to the new records, obtained originally from the field studies and the citizen science data. It was recorded for the first time from 19 of 81 Turkish provinces (Ankara, Antalya, Balikesir, Bolu, Bursa, Istanbul, Izmir, Karaman, Kastamonu, Kirklareli, Kocaeli, Mugla, Rize, Samsun, Sinop, Tokat, Trabzon, Yalova, and Zonguldak) from Aegean, Central and Eastern Black Sea regions. We used the MaxEnt program to predict the current and future potential geographical distribution of this species in Turkey and its surrounding areas. Based on MaxEnt predictions, the majority of this region seems highly suitable for the species.Öğe Karyotypes of Bats (Chiroptera: Rhinolophidae, Vespertilionidae) from Jordan(ARABIAN GULF UNIV, 2008) Karatas, Ahmet; Wedyan, Mohammed; Sozen, Mustafa; Shehab, Adwan; Amr, ZuhairThe karyotypes of four bat species of two families (Rhinolophidae and Vespertilionidae) were examined from Jordan. Bat specimens were captured by use of mist-nets and hand-nets from three localities in Jordan in June 2006. Chromosomes were obtained from femoral bone marrow cells and about 20-30 metaphase cells of each animal were examined. The diploid number of chromosomes (2n) and the fundamental numbers of chromosomal arms (NFa) were determined to be 2n=58 and NFa=60 for Rhinolophus ferrumequinum, Rh. euryale and Rh. blasii, and 2n=44, NFa=50 for Pipistrellus kuhlii. Karyology of Rh. euryale and P. kuhlii is investigated from Jordan for the first time. The karyotypes of Jordanian bats show similarity to other populations in other countries with respect to the diploid chromosome number, however, the fundamental chromosome number and the number of autosomal arms are quite different.Öğe Karyotypes of seven rodents from Jordan (Mammalia : Rodentia)(MAX KASPAREK VERLAG, 2008) Soezen, Mustafa; Karatas, Ahmet; Alsheyab, Fawzi; Shehab, Adwan; Amr, ZuhairWe 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= 56, 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.Öğe Karyotypes of two Iranian bat species, Myotis blythii and Miniopterus schreibersii (Chiroptera : Vespertilionidae, Miniopteridae)(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2008) Karatas, Ahmet; Charakheloo, Muhammed Mouradi; Kankilic, TeomanThe 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.Öğe Molecular ecology and phylogeography of the bent-wing bat complex (Miniopterus schreibersii) (Chiroptera: Vespertilionidae) in Asia Minor and adjacent regions(WILEY, 2009) Furman, Andrzej; Coraman, Emrah; Bilgin, Rasit; Karatas, AhmetIn this study we investigate population genetic structure and phylogeography of the bent-wing bat complex (Miniopterus schreibersii) in Asia Minor and adjacent regions. PCR amplification and sequencing of the first hypervariable domain of the mitochondrial control region were used to obtain the genetic data. Morphometric differentiation between lineages was analysed by comparing forearm lengths. We found two reciprocally monophyletic lineages within the M. schreibersii complex, identified as M. s. schreibersii and M. s. pallidus. Distributions of the lineages were allopatric with a U-shaped suture zone passing through Central Anatolia. The suture zone separated coastal regions occupied by M. s. schreibersii from inland, higher altitude regions occupied by M. s. pallidus. The lineages showed a considerable sequence divergence of c. 9%, accompanied by a corresponding difference in forearm length. The presence of the genetically distinct lineages, with allopatric distribution and corresponding morphometric differences, probably reflects their long isolation during the ice-age in the Balkans and the Caspian/Caucasus refugia, followed subsequently by expansion into different habitats. Based on the present data, the lineages can be recognized as evolutionary significant units.Öğe On the distribution, taxonomy and karyology of the genus Plecotus (Chiroptera: Vespertilionidae) in Turkey(2003) Karatas, Ahmet; Yi?it, Nuri; Çolak, Ercüment; Kankiliç, TolgaPlecotus auritus and Plecotus austriacus were recorded from 8 and 3 localities in the Asiatic part of Turkey, respectively. It was determined that the length of the first premolar, the shape of the zygomatic arches and baculum distinguish these taxa from each other. Apart from these morphological characteristics, the tibia length of P. austriacus was found to be significantly greater than that of P. austriacus (P < 0.05). The diploid chromosome numbers were identical in both taxa (2n = 32). The number of chromosomal arms (FN = 54) and the number of autosomal chromosomal arms (FNa = 50) were the same as in previously published papers on P. austriacus.
