WOS: 000393615100007, Allozyme variations of Tristram's jird Meriones tristrami, which is distributed in the steppe and semiarid areas of Turkey, were studied using 24 loci of 83 specimens from ten locations in Turkey. Seven loci were found to be polymorphic. According to the patterns of allozyme variation, the percentage of polymorphic loci was 12.5. F-ST was found to be 0.44, indicating high genetic variations among M. tristrami; accordingly the Nm value (0.3157) appeared quite low. The UPGMA dendrogram, based on genetic distance, showed that the populations established two very close subclusters, and supported the idea that the westernmost population connected to the northern part of the central Anatolian population. As expected, the eastern population appeared to be more divergent due to geographic distance. Our findings supported that genetic isolation among these subpopulations might be caused by geographic isolation., Ankara University-BAP (TUBITAK, Turkey) [09H4240003, TBAG-107T324], This research was financially support by Ankara University-BAP 09H4240003 and TBAG-107T324 (TUBITAK, Turkey).

WOS: 000323423000012, Fatty acid profiles of total, neutral, and polar lipids in the liver, muscle, and intestine of female individuals of Vimba vimba (L., 1758) were determined by gas chromatography. C16:0, C16: 1 n-7, C18:1 n-7, and C18:1 n-9 were the most abundant fatty acids in total and neutral lipids in all tissues investigated. In addition to these acids, C20:4 n-6 (arachidonic acid) and C22:6 n-3 (docosahexaenoic acid) were the other fatty acids having high percentages in the polar lipid fraction of the tissues. The highest and lowest n-3 to n-6 ratios, which are a good indicator of the quality of fish oils, were determined in the muscle (1.68) and liver (0.68) in the polar lipid fraction, respectively. It was determined that the species had low levels of the n-3 forms of polyunsaturated fatty acids in the investigated tissues. For a better understanding of fatty acid metabolism of V. vimba, more detailed studies are required in terms of feeding experiments.

WOS: 000325268300014, In this study, Spanish Sparrows were recorded in numerous locations and specimens were collected from Samsun, Corum, and Denizli provinces in Turkey. The breeding subpopulations preferred various nesting sites, including wooded areas and White Stork nests. These sparrows were primarily observed in flocks of variable size and were rarely solitary. The largest flock recorded was found in juniper and pine woods in Denizli. We collected data on 23 allozyme loci to compare the genetic variation among the 3 Spanish Sparrow subpopulations. The low F-ST (0.1363) and high Nm (1.5842) values calculated from these data indicated that gene flow among the 3 subpopulations was high and that these subpopulations did not show substantial genetic isolation. The genetic distance (D) between Corum and Denizli was particularly low (0.001), and these subpopulations showed the highest level of genetic similarity found in the study. Conversely, a high genetic distance (0.028) was found between Denizli and Samsun. The genetic structure of these subpopulations also demonstrated a low level of heterozygosity in the total population.

WOS: 000365097200016, The biodiversity of microorganisms is still not understood exactly because they are very small and diverse and it requires an intensive effort to examine them. In this study, we tested whether there were differences in species richness and species composition among six sampled habitats to understand the biodiversity pattern of bdelloid rotifers. To test habitat preferences of bdelloid rotifers, 90 samples were collected from six different habitats (soil, tree bark, one species of lichen (Lecanora muralis), and three species of moss (Grimmia pulvinata, Homalothecium lutescens, and Tortula ruralis)) in the village of Tasci in December 2008. We performed an analysis of variance (ANOVA) followed by a Tukey honestly significant difference (HSD) test to understand whether species richness was significantly different among the six habitats. Analysis of similarity (ANOSIM) was used to test whether differences in species composition between habitats were higher than those between samples within each habitat. The results showed that species richness in each sample was significantly different among habitats (ANOVA: F-5,F-84 = 19.3, P < 0.0001) according to the Tukey HSD test. Differences in species composition between samples between habitats were significantly higher than differences in species composition between samples within each habitat (ANOSIM: R = 0.40, P = 0.001).

WOS: 000309796500013, Seasonal variations in the liver and muscle fatty acid composition of Alburnus chalcoides (Guldenstadt, 1772) from Todurge Lake (Sivas, Turkey) were determined. The most abundant fatty acids in the investigated seasons and tissues were C16:0, C18:0, C18:1 n-9, C18:1 n-7, C20:4 n-6, C20:5 n-3, and C22:6 n-3. The total saturated fatty acids (SFAs) of the liver and muscle were at the highest in the spring (38.59%) and summer (41.65%), respectively. The total monounsaturated fatty acids (MUFAs) were at the highest in the autumn (51.79%) for liver and in the winter (40.04%) for muscle. The total polyunsaturated fatty acids (PUFAs) were determined to be at the lowest levels in the autumn for the both liver and muscle. The lowest total n-6 PUFA levels were determined as 2.60% and 4.19% in the autumn for the liver and muscle, respectively, while the lowest total n-3 PUFA levels were 14.84% for the liver (autumn) and 22.60% for muscle (spring)., Scientific Research Foundation of Cumhuriyet University (CUBAP) [F-243], This work was supported by the Scientific Research Foundation of Cumhuriyet University (CUBAP) with the project number F-243 and derived from the fatty acid composition of Chalcalburnus chalcoides, which is a part of a PhD thesis. For this reason, we want to convey our special thanks to CUBAP. We also thank Professor Abdurrahman AKTUMSEK for his kind guidance during the fatty acid analyses.
