Evaluation of the adaptation process of a reintroduced anatolian mouflon (ovis gmelinii anatolica) population through studying its demography and spatial ecology

Özüt, Deniz
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 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 – 3435 ha. (Mean ± SE: 1934 ± 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 – especially medium to high slope terrain – (slope > 30°, 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.


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 ...
Camera trapping large mammals in yenice forest habitats : a feasibility study for camera trapping large mammals in Yenice Forests, Turkey
Can, Özgün Emre; Togan, İnci Zehra; Department of Biology (2008)
Widely applicable, quantitative field methods are needed to gather wildlife data for conservation and management initiatives in Turkey. In order to evaluate the use of camera traps in forest habitats of Turkey, we conducted a 5 phase camera trap survey by using 16 passive infrared-triggered cameras with a total sampling effort of 1200 camera trap days in Yaylacık Research Forest, a 50 km2 forest patch of Yenice Forest in Karabük during January-May 2006. The camera trap survey confirmed the presence of grey ...
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...
Discovering functional interaction patterns in protein-protein interaction networks
Turanalp, Mehmet E.; Can, Tolga (Springer Science and Business Media LLC, 2008-06-11)
Background: In recent years, a considerable amount of research effort has been directed to the analysis of biological networks with the availability of genome-scale networks of genes and/or proteins of an increasing number of organisms. A protein-protein interaction (PPI) network is a particular biological network which represents physical interactions between pairs of proteins of an organism. Major research on PPI networks has focused on understanding the topological organization of PPI networks, evolution...
Determination of polymorphism of pgm, hk, pgi, and g6pd in different developmental stages of honey bee (apis mellifera l.) and its relation with pgm activity and glycogen content
Yeni, Filiz; Kence, Meral; Department of Biology (2010)
In this study, three subspecies of Apis mellifera L. (A. m. caucasica, A. m. carnica, and A. m. syriaca) from different climatic regions were evaluated electrophoretically at ontogenetic level by means of four enzymes, namely Phosphoglucomutase (PGM), Hexokinase (HK), Phosphoglucose isomerase (PGI) and Glukose-6-phosphate dehydrogenase (G6PD). It is determined that only Pgm and Hk loci were polymorphic. Allele and genotype frequencies at Pgm locus changes seasonally whereas Hk locus does not exhibit seasona...
