    Cataloging the genetic diversity of bats (order : chiroptera) in Turkey
    (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2012., 2012.) Yiğit, Zirve.; Bilgin, Raşit.
    In this study, 26 bat species from Turkey and surroundings were investigated with the cytochrome-oxidase subunit I (CO1) barcoding method. Twelve CO1 sequences from Barcode of Life Database (BOLD) and Genbank and 134 specimens from Turkey and surroundings were analyzed. Neighbor-joining (NJ) and maximum-likelihood (ML) trees were generated and haplotype networks were prepared. For each species sequences were identified in BOLD, and a BOLD tree of each species was obtained for intraspecific and interspecific comparisons. Previous studies regarding Turkish bat fauna were reviewed to make species classifications based on morphological taxonomy. We found that at least six species have high intraspecific divergence and are good candidates for discovery of cryptic species or subspecies for the Turkish population. We found two species show high intraspecific divergence between the Turkish population and other populations. We conclude that, at least for bats, CO1 barcoding is a promising method for discovery of new taxa, as well as being a quick and efficient identification method.

    Determination of the population genetic structure of Miniopterus schreibersii in the Anatolian transition zone
    (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2008., 2008.) Çoraman, Emrah.; Furman, Andrzej.
    Populations and species boundaries of Miniopterus schreibersii were investigated in Thrace and central Anatolia, using the sequenced segments of a mitochondrial DNA control region. Analyses confirmed the presence of two distinct forms of M. schreibersii, namely M. s. schreibersii and M. s. pallidus. The results showed that the forms separated approximately 750,000 years before present and underwent the subsequent expansions of their populations. The percent of genetic variance among clades was very high compared to variances within the clades, indicating a significant mitochondrial separation between forms. Analysis indicated that the range of M. s. schreibersii in Turkey included Thrace and all coastal regions, whereas M. s. pallidus occupied the inland regions of central Anatolia. The results also pointed out to a significant difference in forearm lengths between M. s. schreibersii and M. s. pallidus. These forms might be distinct species, rather than subspecies, as they are recognized now.

    The summer populations of cave-dwelling bat species of Çatalca-Kocaeli region and environmental region and environmental factors that influence their distribution
    (Thesis (M.S.)- Bogazici University. Institute of Environmental Sciences, 2000., 2000.) Bilgin, İbrahim Raşit.; Furman, Andrzej.
    The summer population of cave dwelling-bat species in Catalca-Kocaeli Region was surveyed between May-August 1999. The effects of geographical location, habitat, and temperature were studied as possible factors in determining the distribution patterns of the bat species in these caves. Nine out of the 11 caves were studied for the first time with regard to the assessment of bat populations inside. Three maternity colonies were identified for Rhinolophus ferrumequinum, R euryale and Minioptems schreiberszi in three different caves. The statistical analysis based on geographical coordinates, and species distribution hinted that Bosphorus might be acting as a natural barrier limiting migration and gene flow between Catalca and Kocadi regions. Hence it may be more correct to treat Catalca and Kocaeli regions separately in terms of species occupancy. The critical habitat types influencing species distribution were traditional arable land, pond, heathland, and maquis. River, riparian treeline, pasture, broadleaved woodland md broadleaved woodmd/pasture edge were the common habitat types recorded for all of the bat species. Habitat surveys around the caves indicated that M. schreibersii might be able to utilize a greater number, and Large Myotis a lesser number of different habitat types, compared to the other species studied. Average temperature in the caves was the weakest contributing factor far explaining the distribution patterns of the species.|Keywords: Chiroptera, Cave, Habitat, Temperature, Turkey
