Increasing levels of conflict between brown bears and rural people have been reported for Yusufeli (Artvin, Turkey). This study aimed to document the conflict, understand human attitudes and responses, determine local habitat use and daily activity patterns of bears, and evaluate available damage prevention techniques. The study was conducted within landscapes at different scales, ranging from a core area defined by a large valley system to the whole of Artvin Province. Data on close encounters, injuries and damages caused were collected through government records, published literature and open-ended interviews with the locals. Bear presence and activity were monitored through various techniques, including the capture and radio-collaring of one individual. Population density was found to range between 11-27 adult bears/100 km2. Bear activity increased during hyperphagia, with many daytime observations. Interviews (n=67) showed that almost all (95%) locals believed that bears have become more of a problem lately. Only 6% supported full protection while 38% conditionally accepted it. On more than two-thirds of close encounters, the bear and person(s) involved departed without any harm. Rare bear attacks on humans, usually provoked, sometimes caused non-fatal injuries. Several bears were found to be shot and killed within the study area in 2002-2005. Damages were mostly in late summer on field crops and orchards, and in spring on beehives. Precautions taken by villagers differed in effectiveness against bears. Bears caused a minimum of US$21,500 worth damages annually at Yusufeli County. Implementation of modern techniques of exclusion and scaring would reduce human-bear conflict in the region.

Brown bear is the largest mammal in Turkey and its main distribution lies in the Black Sea and Eastern Anatolia Regions. Its basic ecology is almost unknown in Turkey, except for a limited number of studies. This study aims to determine the spatio-temporal ecology and habitat use of brown bears in the Ka&ccedil / kar Mountains, and to estimate their population size in the &Ouml / zg&uuml / ven Valley and Yusufeli, both firsts for Turkey. The study area is primarily covered with conifer and oak stands, but sparse mixed shrubland occurs in the Mediterranean climate influenced lower parts. GPS-GSM telemetry on seven captured bears (5 males and 2 females) was the main field technique used in this study. Other methods include monitoring via camera trapping, visual direct observations, and counting cubs of the year. Bears were fitted with GPS-GSM collars and tracked for 3 to 603 days. Mean home range size (HRS) was calculated by 95% kernel and MCP estimators for three different samples sizes.95% MCP for all positions produced a home range size of 19.91 &plusmn / 8.89 sq. km. for females, and 130.68 &plusmn / 102.95 sq.km. for males. On average, males and females move at rates of 199 m/h and 129 m/h, respectively. Males hibernate around 140 days whereas females around 150 days and at lower elevations than males. According to camera trapping results, bears are generally active at twilight whereas activity data loggers produced disparate results for tracked bears. Resting patterns showed that bears may also rest at midnight. Estimated population density per 100 km2. is 24.50 &plusmn / 1.74 individual using the Fcub method and 23.85 &plusmn / 2.51 using the mark&ndash / resight method. Captured bears indicated nonrandom distribution on habitat use and selected productive croplands and shrublands than other types of vegetation. Brown bear HRS in the Ka&ccedil / kars is smaller than reported from most countries. The large female-male HRS difference is probably due to polygamous mating system, sexual dimorphism, hard mast availability, high population density, and female&rsquo / s habitat exclusivity as a result of high tolerance by the local people in contrast with most northern countries. Although primary productivity is used to explain high population density and small HRS in other countries, the low productivity in the study area cannot explain the observed density and HRS difference. These findings will construct a scientific basis for brown bear management and conservation in Turkey.

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 Sanlurfa. In this theses, demographic structure and population parameters of natural population goitered gazelle in Sanliurfa is studied. Line transect and regular surveys are performed to collect data about demographic structure of the population such as sex ratio and group composition. Line transect sampling, which is a distance sampling technique, is used to estimate population size and density of the population. GPS collared goitered gazelles are monitored for fecundity and survival rate. Data is collected for 18 from July 2008 to December 2009 during 32 field surveys. Four main transect samplings have been performed and including transect samplings that are done during regular surveys, 90 line transects are walked. Population sizes and densities were estimated to be (average &plusmn / standard error) 242 &plusmn / 184 and 2.302 &plusmn / 1.590 individual per km2 for July 2008 / 365 &plusmn / 179 and 3.476 &plusmn / 1.707 individual per km2 for January 2009 / 319 &plusmn / 111 and 3.039 &plusmn / 1.059 individual per km2 for June 2009 and lastly, 317 &plusmn / 243 and 3.019 &plusmn / 2.315 for November 2009. Survival rate is estimated to be 0.276, 0.540 and 0.585 for calves, 1 year old and 2+ years olds respectivelty, and fecundity is estimated to be 0.4. This preliminary study shows that according to Population Viability Analysis results, natural goitered gazelle population in Turkey will be extinct in next 10 years if more effective conservation is not performed.

Goitered gazelle is one of the threatened species of Turkey living in only &amp / #289 / anliurfa region. In this study, goitered gazelles have been released to their previous habitat in Sanliurfa-Suru&ccedil / 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 &plusmn / 0.47 km2 for winter, 3.96 &plusmn / 0.44 km2 for spring, 4.55 &plusmn / 1.35 km2 for summer1, 2.26 &plusmn / 0.20 km2 for summer2, 3.38 &plusmn / 0.44 km2 for autumn, 1.37 &plusmn / 0.50 km2 for mating season, and 1.66 &plusmn / 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.

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 Sariyar 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 population according to the age groups (females, 0: 0.5423, 1: 0.60, 2: 0.5316, 3: 0.6637, 3+: 0.6728) and the fecundity of adult females (2: 0.2260, 3: 0.2034, 3+: 0.2034) are estimated. A population viability analysis was performed and the persistence of the population within the next 20 years was estimated. Increasing the survival rate of adult female through conservation or restocking the population with at least six adult females every year decreased the risk of extinction in the near future considerably. The year-round home ranges of the individuals ranged between 805 &ndash / 3435 ha. (Mean &plusmn / SE: 1934 &plusmn / 140 ha). The movements of the tracked individuals followed seasonal patterns: centers of activities changed according to seasons in 80% of the adult mouflon. Reintroduced mouflon selected southern aspects (p=0.001), increasing slopes &ndash / especially medium to high slope terrain &ndash / (slope &gt / 30&deg / , p=0.002), and distant locations to villages and roads. Results indicate that appropriate protective measures should be implemented immediately to mitigate the causes of juvenile mortality. Restocking the population for the next 10 years with adult females would have a stabilizing effect on the declining population and will act as a buffering mechanism during the adaptation period to the new area.

The Anatolian mouflon (Ovis gmelinii anatolica) is an endemic ungulate subspecies and of IUCN Vulnerable status that inhabits Konya-Bozdag region located in Central Anatolia. In this thesis, the demography and habitat use of the only natural population of Anatolian mouflon at Konya-Bozdag Provice is studied. Throughout the study, distance sampling techniques, specifically line transect sampling, are used to estimate density, size and growth rate of this population. Sex, age and count data are used to estimate relevant parameters. Changes in population structure and seasonal area use are monitored for two years. Data is collected during repeated random line transects from May 2007 to July 2009. Line transect method is preferred since it requires less effort and is less expensive when compared to the complicated techniques that need animal marking or radio tagging. In total, 78 transect lines were surveyed during the time which covers 3 lambing periods. In spite of the paratuberculosis epidemics in the fenced area which has affected the population adversely in the previous years, a rather stable population trend is observed. The post-breeding population size in 2007, 2008 and 2009 were estimated to be 883+-241, 939+-136, 972+-243 (average+-satndard error) and densities as 27.227, and 28.186 individuals per sq km, respectively. Growth rate of population is found using the ratio of the population size estimates of consecutive years from 2007 to 2009, average 1.0495+-0.0203. Habitat use patterns of the Anatolian mouflon throughout the study period are investigated according to seasons and sex groups. There is sexual segregation in the Anatolian mouflon population in Konya Bozdag Province, with the females using the western part and males using the eastern part of Bagderesi. Seasonal patterns affect on the area use of animals, group formation and compositions and the relationship between them are searched throughout the study. The movements of the individuals and groups followed seasonal patterns as centers of activities changed according to seasons.

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 km2 large pine woodland near Ankara. Brown bear (Ursus arctos), wolf (Canis lupus), Eurasian lynx (Lynx lynx), golden jackal (Canis aureus), jungle cat (Felis chaus), red fox (Vulpes vulpes), Eurasian badger (Meles meles), stone marten (Martes foina), red deer (Cervus elaphus), wild boar (Sus scrofa), brown hare (Lepus europaeus), Caucasian squirrel (Sciurus anomalus) and southern white-breasted hedgehog (Erinaceus concolor) were the 13 mammal species captured during the study. Spatial segregation was observed among canid species indicating intraguild competition and competitive exclusion. Prey-predator interactions were documented at both spatial and temporal scales between wolves, deer and wild boars. Red deer showed seasonal and sex differences in activity patterns that appeared to be influenced by wolf predation risk. The presence of two felids unknown to the local people were revealed by camera trapping, showing the utility of this technique for such secretive and rare species. However, the low encounter rates for particular species such as lynx, brown bear and jungle cat indicated the importance of the length of study. Based on various evidence, resident adult population sizes were estimated for wolf (2-5), Eurasian lynx (2-4), brown bear (0-2) and jungle cat (2-3). The study showed that lynx can exist in high densities in a relatively small area when prey species are abundant. This study area hosted a rich mammal fauna in spite of human activities such as livestock grazing, logging and hunting. A relatively intact ecosystem, high altitudinal and habitat diversity, and a positive attitude of local people are believed to be the reasons of this observed high diversity.
