    Allozyme Variations in the Genus Meriones (Gerbilinae: Rodentia) from Turkey
    (INST ZOOLOGY, BAS, 2013) Yigit, Nuri; Colak, Ercument; Saygili, Fulya; Yuce, Duygu
    Allozymic variability of 24 loci was compared in the genus Meriones representing 5 species in Turkey. The phylogenetic relationship of these Meriones species was established according to the variations of twelve polymorphic loci (Aid, Ldh, alpha-Gpdh, Ca-1, Ca-2, Gpi, Me, Mpi, G6pdh, Ldh-1, Sod, Ak). According to the patterns of allozyme variation, the percentage of polymorphic loci was found to be 12.5 in Meriones crassus, 16.7 in Meriones persicus, 12.5 in Meriones tristrami, 18.7 in Meriones vinogradovi and 8.3 in Meriones dahli. Interspecific genetic distances were found to be high, ranging from 0.032 to 0.332. Neighbor-joining and UPGMA dendrograms showed that M tristrami and M crassus have a high genetic similarity. The most diverged one was appeared to be M vinogradovi. It was also concluded that the genus Meriones is not monophyletic since M persicus, which belongs to a different subgenus, was placed between the clades of M tristrami, M crassus and M vinogradovi.

    Morphometric and allozymic differences between Bearded Tit Panurus biarmicus (Ayes: Passeriformes) subpopulations in a large wetland and a small pond in central Anatolia, Turkey
    (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2013) Saygili, Fulya; Yigit, Nuri; Cam, Pinar; Yuce, Duygu
    The Bearded Tit (Panurus biarmicus) is a small passerine bird occurring only in wetland habitats. Three subspecies of the Bearded Tit are known from Turkey. The endemic subspecies Panurus biarmicus kosswigi has only been recorded from Amik Lake in Turkey. This subspecies is now considered extinct; the apparent cause of this extinction was the drought affecting the lake. Other subpopulations might be similarly threatened by habitat loss. Therefore, it is important to investigate the morphometric characteristics and genetic variation of these local subpopulations. In this study, body weights and 12 morphometric characters were measured for Bearded Tit individuals in the Eber Lake and Behicbey reedbed subpopulations. Statistically significant differences were found in extended wing length, maximum wing chord, and weight between the 2 subpopulations. Allozymic variation was also studied in the 2 subpopulations. Genetic variation was assessed using isozyme systems, and 8 of 21 loci (Pgm, Me-I, Me-II, Fum, Est, Mpi, Pgd, and Acon-M) were found to be polymorphic. The percentage of polymorphic loci was higher at Eber Lake (P-95% = 38.1%) than in the Behicbey reedbed (P-95% = 33.3%). The mean F-ST (0.048) and Nm (5.0) values showed high levels of gene flow between these subpopulations.
