Goitered gazelle is one of the threatened species of Turkey living in only ġanlıurfa region. In this study, goitered gazelles have been released to their previous habitat in Şanlıurfa-Suruç region and seven of females were collared with GPS collars. These individuals were monitored for a year and their seasonal habitat selection and home range sizes are determined by using location data recorded on the collars. In addition to 4 seasons of the year, home range and habitat selection are estimated for mating and calving periods. Also, summer period is divided to two as summer1 and summer 2 because of changing availability of water resources in study area. Seasonal home range sizes of GPS collared gazelles are estimated as average 3.61 ± 0.47 km2 for winter, 3.96 ± 0.44 km2 for spring, 4.55 ± 1.35 km2 for summer1, 2.26 ± 0.20 km2 for summer2, 3.38 ± 0.44 km2 for autumn, 1.37 ± 0.50 km2 for mating season, and 1.66 ± 0.50 km2 for calving season.Seven habitat variable layers were prepared for the evaluation of seasonal habitat selection of GPS collared female gazelles. Gazelles were selected east aspects in summer and west aspects in winter seasons and, north and flat aspects were avoided in all seasons for a year. Water can be considered the key habitat variable for the goitered gazelles. The results show that some home ranges are outside of the protected area and gazelles do not use large areas in the protected area. In order to improve conservation of gazelles, protected area should be re-arranged and shifted to more intensely used areas by gazelles.

Identification of demographic structure and population viability analysis of Gazella subgutturosa in Şanliurfa Çobanoğlu, Aziz Emre; Kence, Meral; Department of Biology (2010) Goitered gazelle (Gazella subgutturosa) is an Asian antelope species and it is classified as Vulnerable by IUCN. They have an economic, esthetic and cultural value; therefore, they had been hunted and domesticated for a long time. Additional human disturbance over years nearly led goitered gazelle populations in Turkey to extinction. Today in Turkey, only natural population of goitered gazelle lives in Şanlurfa. In this theses, demographic structure and population parameters of natural population goitered g...
Characterization of taxonomically related some Turkish oak (quercus l.) species in an isolated stand : a morphometric analysis approach Aktaş, Caner; Kaya, Zeki; Department of Biology (2010) The genus Quercus L. is represented with more than 400 species in the world and 18 of these species are found naturally in Turkey. Although its taxonomical, phytogeographical and dendrological importance, the genus Quercus is still taxonomically one of the most problematical woody genus in Turkish flora. In this study, multivariate morphometric approach was used to analyze oak specimens collected from an isolated forest (Beynam Forest, Ankara) where Quercus pubescens Willd., Q. infectoria Olivier subsp. boi...
An inventory of medium and large mammal fauna in pine forests of beypazari through camera trapping Mengüllüoğlu, Deniz; Bilgin, Cemal Can; Department of Biology (2010) Information about large mammals in Turkey usually does not go further than species lists or annual counts of particular species such as the wild goat. Camera trapping is a very useful technique to overcome this deficiency by gathering information about species presence, numbers, habitat use and behavior. Hence, a one year long camera trap study was conducted to demonstrate the diversity, activity, distribution patterns, habitat preferences and interspecific interactions of medium and large mammals in a 148 ...
Founder effect in reintroduced Anatolian Mouflon ovis gmelinii anatolica valenciennes 1856 populations Kayım, Mehmet; Kence, Aykut; Department of Biology (2008) Reintroduction of Anatolian mouflon population at Bozdağ Protection & Breeding Station to its former habitats(Emremsultan Wildlife Development Area in Ankara-Nallıhan, and Karadağ in Karaman) started in 2004. The magnitude of genetic change among Bozdağ and reintroduced populations was evaluated by 11 microsatellite loci. Study populations revealed close results (±st.dev.) Bozdağ population: nk = 2.9091 (±1.1362), AE = 2.0250 (±0.9537), Ho = 0.3830 (±0.2717), He = 0.3956 (±0.2746); Nallıhan population: nk ...
Evaluation of the adaptation process of a reintroduced anatolian mouflon (ovis gmelinii anatolica) population through studying its demography and spatial ecology Özüt, Deniz; Kence, Aykut; Department of Biology (2010) In this thesis the demography, home range and habitat selection of a reintroduced population of Anatolian mouflon (Ovis gmelinii anatolica), which had a single remaining population, was studied to evaluate the reintroduction success and determine the conservation management interventions. For this purpose among 104 individuals reintroduced in Sarıyar Wildlife Protection Area (Ankara, Turkey), 40 adults were radio-collared and 28 juvenile were ear-tagged and monitored from 2005 to 2009. The survival of the p...
