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 seasonal variation. Within the scope of this study we investigated at which developmental stage shifting to heterozygotes prior to winter occurs. It is found that there is a seasonal fluctuation throughout the year in Pgm genotype frequencies at each developmental stage studied and correlated with enzyme activity and glycogen content. As the studied enzymes have crucial v roles in insect energy metabolism, results of this study provided further information about the relationship between carbohydrate metabolism and enzyme polymorphism of honey bees.

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...
Mitochondrial dna (mtdna) haplogroup composition in Turkish sheep breeds
Yüncü, Eren; Togan, İnci Zehra; Department of Biology (2009)
In the present study, haplogroup composition of five native Turkish sheep breeds, (Karayaka, Akkaraman, Gökçeada, Dağlıç, Morkaraman) and two sheep breeds from neighboring countries (Herik from Iran, samples from Azerbaijan) were determined by single strand length polymorphism (SSCP) analysis of mitochondrial DNA (mtDNA) NADH dehydrogenase subunit 4 (ND4) region and restriction fragment length polymorphism (RFLP) analysis of mtDNA control (CR) region. Results of the SSCP and RFLP approaches were found to be...
Detection of species boundaries in the Rana Ridibunda complex of Southwestern Turkey using mitochondrial ND3 marker
Akın, Çiğdem; Bilgin, Cemal Can; Department of Biology (2007)
Water frogs are one of the most interesting vertebrate groups, showing great diversity and complexity in their reproductive modes, ecology and evolutionary relationships, and with many cryptic species due to high morphological similarity. For many decades, a single species, Rana ridibunda, has been suggested to exist in Turkey. However, the application of new morphometric, molecular and bioacoustic techniques has recently revealed the occurrence of several distinct water frog taxa in Turkey. In this study, ...
Avian community patterns in the lesser caucasus (northeastern turkey)
Atkın Gençoğlu, Gülden; Bilgin, Cemal Can; Department of Biology (2007)
Species composition, diversity and species-habitat relations are widely used to describe communities. This study aimed to document diversity, composition and habitat relations of avian communities of the Turkish Lesser Caucasus by using point counts and multivariate analyses. 2845 individuals of 101 bird species were observed at 215 stations located in the study area. Point counts were revealed to be a useful method for terrestrial birds, especially passerines. Species richness and diversity changed signifi...
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...
