The Fallow Deer (Dama dama) population in Turkey is presumed to be one of the few autochthonous populations globally. Although the species has been under protection since the 1960s, it had become restricted to a single site in Düzlerçamı, Antalya. Within the context of a reintroduction project, 21 deer were translocated into Dilek Peninsula National Park (Aydın, Turkey) in 2011 and 2012. Fifteen individuals were GPS-collared and monitored between 2011 and 2013 to understand their movements, habitat choice and social interactions. Annual average home range size is estimated to be 587±321 ha for males and 564 ±297 ha for females. Habitat selection analyses revealed that males and females differ in habitat use, except during mating seasons. Habitat selection is stronger in females, and the abundance and quality of resources shape space use pattern in females. On the other hand, predation potential of the habitats likely determines habitat selection of males. Significant sexual segregation occurs, except during mating seasons. Two hypotheses are tested to find out the underlying reason for sexual segregation. Forage selection hypothesis better explains observed spatial utilization differences between sexes. Males use both non-territorial and single territory strategies during mating. Demographic variables were estimated using closed population mark-resight models and camera trap records. Population size has increased over the study period with an average growth rate of 0.24 ±0.10, and reached an estimated 48.17±3.29 in 2016. Our results indicate that the reintroduced individuals have successfully adapted to the new environment and expanded their range into favourable habitats.

Conflicts between humans and wolf : a study Bozdağ, Konya province, Turkey Tuğ, Senem; Bilgin, Cemal Can; Department of Biology (2005) Canis lupus is one of the most important but least studied species of Turkish fauna, however, livestock depredation and recently increased number of publications on attacks on humans intensifies human-wildlife conflict. In this study, wolf depredation is studied in Bozdağ in the province of Konya where conflicts between wolves and livestock holders are well known. The study site holds >50,000 sheep and covers 9 villages and a small town. A total of 13 shepherds are interviewed in 2004 and 2005 to reveal hus...
Breeding success and reproductive behavior in a white stork (ciconia ciconia) colony in Ankara Göcek, Çağrı; Bilgin, Cemal Can; Department of Biology (2006) White Stork ( Ciconia ciconia, Linnaeus, 1758) is a summer visitor and passage migrant in Turkey. Although being widespread in summer near wetlands of Turkey, except for the eastern and western parts of the Black Sea Region, there has been no research on this species involving regular monitoring of nests. In this study, breeding success and survival of nestlings in a population in Kızılcahamam-Ankara as well as behavioral differences among nests and their probable consequences on breeding success were studi...
Genetic diversity of gazelles (gazella marica and gazella gazella) in Southeast Turkey: with a special emphasis on ongoing conservation studies of gazella marica in Turkey Saatoğlu, Dilan; Togan, İnci Zehra; Department of Biology (2015) The present study was conducted to confirm the recently suggested taxonomic status of gazelles in Turkey and also to investigate genetic diversity that exists between and within populations of Gazella marica (One from Kızılkuyu State Farm, Şanlıurfa, n=48; one from Erikçe State Farm, Gaziantep, n=25) and Gazella gazella (population from Kırıkhan County, Hatay, n=4). In the frame of the study, partial mtDNA cyt-b sequence (amplified by the primers: L14724, H15149), 17 microsatellite loci (RT1, ETH10, OARFCB3...
Determination of home range size and habitat selection of Gazelles (Gazella subgutturosa) by GPS telemetry in Şanliurfa Durmuş, Mustafa; Kence, Meral; Department of Biology (2010) 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 a...
Polymorphism of Prolactin (PRL), Diacylglycerol Acyltransferase (DGAT-1) and Bovine Solute Carrier Family 35 Member 3 (SLC35A3) genes in native cattle breeds and its implication for Turkish cattle breeding Kepenek, Eda Şeyma; Togan, İnci Zehra; Department of Biology (2007) In the present study samples from four native Turkish Cattle Breeds; South Anatolian Red (n= 48), East Anatolian Red (n= 34), Anatolian Black (n= 42) and Turkish Grey (n=46) and elite bulls of Holstein (n=21) were genotyped with respect to two milk production enhancer genes, Prolactin (PRL) and Diacylglycerol acyltransferase (DGAT1), and one disease (Complex Vertebral Malformation) causing gene (SLC35A3). A allele frequency for PRL gene, believed to be positively associated with the milk yield in cattle, ra...
