Öğe Avrasya Su Samuru, Lutra lutra (Linnaeus, 1758)'nın Türkiye'deki Yayılış Kayıtları(2016) Toyran, Kubilay; Albayrak, İrfanMemeli sınıfının Carnivora takımına ait Lutra cinsi dünyada 13 türle temsil edilmektedir. Bu türlerden Avrasya su samuru (Lutra lutra) Palearktik bölgede geniş bir yayılış alanına sahiptir. Avrasya su samurunun Türkiye'deki durumu ile ilgili yapılan ilk üç sempozyumun sonucuna göre Lutra lutra'nın Türkiye'nin her yerinde yayılış gösterdiği belirlenmiştir. Lutra lutra dere, çay, nehir, göl ve akarsuların denize döküldüğü yerlerde kaydedilmiştir. Yapılan dışkı analizlerine göre Avrasya su samurunun yayılış gösterdiği bölgelerde besin tercih oranlarının değişmesine karşın, genel olarak başta balık olmak üzere midye, tatlı su yengeci ve kerevit gibi omurgasız hayvanlar ile iki yaşamlı, sürüngen, küçük yapılı kuş ve memeli gibi omurgalı türlerini besin olarak tercih etmektedir. Su samurunu tehdit eden başlıca faktörler arasında yaşam alanının tahrip edilmesi, araç çarpması, çevre kirliliği, pestisit, çiftlik sahipleri tarafından balık havuzlarını koruma amaçlı öldürme ve kısmen avcılık gelmektedir. Lutra lutra'nın uluslararası koruma statüsü 2000'li yılların başında IUCN kriterlerine göre "Vulnerable" iken, 2004'den bu yana "Near Threatened" olarak değişmiştir. Türkiye'de de bu tür "Near Threatened" kategorisinde yer almaktadır. Türkiye'nin değişik bölgelerinde rastlanan su samuruna yönelik tehditlerin boyutlarına göre koruma önlemleri alınabilir. Bunun için su samurunun yaşam alanlarının ve ekolojik tercihlerinin tam olarak bilinmesi gerekmektedirÖğe Bats in Southeastern Turkey (Mammalia: Chiroptera)(2020) Yorulmaz, Tarkan; Toyran, Kubilay; Albayrak, İrfanSoutheastern Turkey is an important geographical region where the bat species spreading especially in Arabian Peninsula, North Africa and the Middle East enter in Turkey and have an intense population. The aim of this study was to identify the bat species in this region, which has glacial mountains, arid steppes, river valleys and vast plains.

The species had a karyotype of 2n=48, NF= 95 in males and 96 in females, NFa=92. C-heterochromatin was observed in 18 biarmed pairs and in the Y chromosome. The nucleolus organizer regions (NORs) were located at the telomeric region of 3 autosomes.Öğe C-banded karyotype and NORs of the long-eared hedgehog, Hemiechinus auritus from Turkey(Inst Vertebrate Biology As Cr, 2009) Arslan, Atilla; Albayrak, İrfan; Pamukoğlu, Nahit; Yorulmaz, Tarkan; Toyran, KubilayThe karyotype, C-banding, and nucleolar organizer regions (NORs) of six specimens of Hemiechinus auritus from Turkey were examined. The diploid number of chromosomes was 2n = 48, the fundamental number of chromosome arms FN = 96, and the number of autosomal arms FNa = 92. Most of the chromosomes possessed centromeric constitutive heterochromatin, except of the pairs nos. 4, 6, 7, 8, 9, 12. and 17. The X and Y chromosomes appeared to be euchromatic. and possible geographic variation in their morphology was indicated in comparison with Previously published data. The NORs were located in the terminal regions of the long arms of four metacentric or submetacentric chromosomes. The localization of the NORs was not associated with C-positive autosomal regions as in hedgehogs of the genus Erinaceus.Öğe C-Banded Karyotype of Myocastor coypus (Molina, 1782) from Turkey (Mammalia: Rodentia)(Polish Acad Sciences, 2009) İlker, Ayşegül; Arslan, Atilla; Pamukoğlu, Nahit; Albayrak, İrfanThe present study reports the C-band patterns of chromosomes of Myocastor coypus fromTurkey. The karyotype of M. coypus is comprised of (2n) 42 chromosomes. the number of chromosomal arms (FN) was 83 and the number of autosomal arms (FNa) was 80. The X chromosome was a medium-sized metacentric and the Y chromosome was acrocentric and the smallest in the set. Two metacentric chromosomes have secondary constrictions. Most autosomes in this species were centromeric C-positive and some autosomes had telomeric C-bands. The X chromosome has centromeric heterochromatin, while the Y chromosome appeared to be entirely heterochromatic.Öğe A comparative study of the reproductive activities of European hare (Lep us europaeus) populations in Turkey(2015) Demirbaş, Yasin; Albayrak, İrfanTo explore whether the reproductive cycle of Lepus europaeus differs within Turkey, a total of 182 hares from Turkish Thrace (transition climate), Central Anatolia (continental climate), the Black Sea (oceanic climate), and the Turkish Mediterranean (Mediterranean climate) were collected between June 2006 and September 2014. We present the length of breeding season, sex ratio, mean litter size, and testicle position of European hares distributed in Turkey for the first time. Among these features, length of breeding season and mean litter size of European hares showed moderate variation in Turkey.Öğe Comparison of the Morphometric Characteristics of Some Species of the Genus Microtus Schrank, 1798 (Mammalia: Rodentia) in the Central Anatolia Region of Turkey(2020) Gözütok, Serdar; Albayrak, İrfanThe aim of this study was to determine and compare some morphometric characteristics of Microtus species occurring in the central Anatolia, Turkey. This study is based on 209 specimens of Microtus spp. collected the central Anatolia between 2003 and 2010. Some features concerning pelage coloration, cranial characters, tooth morphotype, and baculum morphology of the species were recorded to determine and evaluate their taxonomic characteristics. It was determined that four species of the genus Microtus occur in the study area, including Microtus dogramacii, Microtus guentheri, Microtus hartingi, and Microtus mystacinus. Microtus hartingi has been found to be widespread throughout central Anatolia. Microtus guentheri is located in the type locality and nearby provinces. M. guentheri and M. hartingi were not found to be sympatric. Among species, M. hartingi has the longest hind foot and M. mystacinus has the longest tail. The UPGMA trees were constructed for each sex, using skull and external measurements of Microtus specimens. As a result, M. dogramacii and M. guentheri being the most similar, and M. mystacinus is the sister species to these. But, it was determined that M. hartingi is distinctively from the these species.Öğe Contribution to the taxonomica and biological characteristics of Sciurus anomalus in Turkey (Mammalia: Rodentia)(2006) Albayrak, İrfan; Arslan, AtillaBu araştırma 1997 ve 2002 yılları arasında Konya, Karaman, Kütahya ve Çorum'dan toplanan 62 Sciurus anomalus örneğine dayanmaktadır. Türün bazı ekolojik ve biyolojik özellikleri ile ilgili olarak habitat, yuva yeri, kürk rengi, baculum ve phallus'u incelendi. Bu türde kromozom sayısı (2n) 40 olarak bulundu. Sciurus anomalus'un taksonomik değerlendirmesi için örneklerin morfometrik verileri kullanıldı. Örnekler, ilgili literatürle karşılaştırılarak alttür seviyesinde tartışıldı ve örneklerimizin nominatif alttürü temsil ettiği sonucuna varıldı.Öğe Contribution to the taxonomical and biological characteristics Sciurus anomalus in Turkey (Mammalia: Rodentia)(2006) Albayrak, İrfan; Arslan, AtillaThis study is based on 62 Sciurus anomalus specimens obtained from Konya, Karaman, Kütahya and Çorum provinces between 1997 and 2002. Some ecological and biological features of the species, including habitat, nest-sites, fur colour, baculum and phallus were investigated. In this species, the chromosome number (2n) is 40. For the taxonomical evaluation of Sciurus anomalus, morphometric data of the specimens were used. The specimens were discussed at the subspecies level, comparing to the relevant literature, and it was concluded that our specimens represent the nominate form. © TÜBİTAK.Öğe Distribution And Ecology Of Lutra Lutra (Linnaeus, 1758) In Kizilirmak River (Turkey)(Pakistan Agricultural Scientists Forum, 2019) Toyran, Kubilay; Albayrak, İrfanThis study was conducted in an about 130-km section of Kizilirmak River located between Hirfanli Dam and border of Kalecik district between February 2005 and August 2009. Footprints and feces of otter were identified and direct observations were made in order to determine its activity areas (including 7 localities). As a result of analysis of 233 fecal samples of otter, preys in its diet were divided into 5 categories as invertebrates, fish, bird, mammal, and unidentified pieces. It was determined that 69.91% of the diet were fish, 18.80% were invertebrate, 4.39% were bird, 4.39% were mammal, and 2.51% were unidentified remains. Habitat characteristics were recorded and habitat quality was calculated for Lutra lutra. Behaviors of Eurasian otter individuals determined as a result of the direct observation were recorded and photos were taken.Öğe The effect of disturbances to habitat quality on Otter (Lutra lutra) activity in the River Kızılırmak (Turkey): A case study(2005) Tüzün, İlhami; Albayrak, İrfanHabitat restriction for otters living in a small part of the K?z?l?rmak River occurred due Mainly to 3 causes: dam construction at the upper end, heavy pollution by oil refinery effluent at the lower end and man-made activities such as housing and angling in-between. Sprainting activity was measured to assess habitat use by otters within the area and differences were shown between the sites. Compared to site II, higher sprainting activity was found at the site below the dam (site 1), where habitat quality was poorer, as indicated by the water quality index (BMWP), diversity indices (Simpson's and Shannon-Wiever) and riparian quality index (QBR). This was due to the relatively more stable standing water formed at the foot of the dam, offering sufficient food availability at this site throughout the year. A site further downstream (site II) had higher river water and riparian habitat quality but flow variations caused by dam operations led to the occurrence of less suitable food conditions for otters at various times of the year. The food items found in spraints from the 2 sites revealed that otters fed on more fish at site 1. No spraints were found in the lowest part of the study area (site III). where heavy pollution occurred due to oil refinery discharge. Incorporation of the previously developed habitat quality indices into otter activity for habitat use was attempted in this study and these indices appeared to be promising tools for the establishment of management strategies for otters. © TÜBİTAK.Öğe Karyotype of Miniopterus schreibersii (Kuhl, 1819) in Turkey (Chiroptera)(Walter De Gruyter & Co, 2006) Albayrak, İrfan…Öğe Kızılırmak Vadisinde Kuşları Etkileyen Olumsuz Faktörler(2015) İliker, Ayşegül; Albayrak, İrfan; Tabur, Mehmet Ali2010-2012 yılları arasında Kızılırmak vadisinde toplam 263 kuş türü gözlenmiştir.
