Mole rats have adapted to living underground and have a wide range chromosomal variation in Turkey, ranging between 2n = 36 and 2n = 60. This study was performed on the subterranean mole rats of the Nannospalax nehringi (Nehring, 1898), sampled around Çanki{dotless}ri{dotless} and Çorum provinces in central Anatolia, and the karyotypes of 91 specimens across 38 localities were analyzed. Different chromosomal forms that have the same 2n values were assigned letters according to their geographic locations in Turkey: C for central forms, N for northern forms, S for southern forms, E for eastern forms, and W for western forms. It was de . . .termined that N.nehring has 2n = 54C, NF = 74; 2n = 56N, NF = 72; 2n = 58N, NF = 74, and 2 different forms of 2n = 60 (NF = 78, NF = 82) in these areas. This study filled the gaps in distribution of blind mole rat chromosomal forms around Çanki{dotless}ri{dotless} and Çorum provinces. The distribution areas of 2n = 54C, 56N, 58N, and 60 forms in the area were brought to light. © TÜBİTAK Daha fazlası Daha az

Makale | 2013 | Turkish Journal of Zoology37 ( 4 ) , pp.470 - 487

We used 33 blind mole rats belonging to 10 different chromosomal races from 10 localities in western Turkey. We applied G-and C-banding techniques to compare chromosomal races as well as clarifying relationships between them. We discussed cytogenetic similarities and differences between chromosomal races. We concluded that 2n = 60C is the ancestor of the other chromosomal races. However, as a result of ongoing evolution processes 2n = 38 and 2n = 60K have become ancestors to chromosomal races on their peripherals. We discovered which rearrangements contribute to the evolution of such a complex chromosomal race system in a genus. Wit . . .h this study we provide a comprehensive comparison of the 10 chromosomal races and perform a cladistic analysis using chromosomal rearrangement character states. According to our tree, chromosomal races with a low diploid number formed a monophyletic group. © TÜBİTAK Daha fazlası Daha az

Multivariate Morphometric and Spatial Autocorrelation Analyses were performed to determine the morphometric variation in Apis florea colonies representing 13 localities from 4 states on the coastal north-south diagonal in Iran. New morphometric characters (hind wing length, hind wing width, and hind wing angles) were also measured to determine the usefulness of these characters for Apis florea. Analysis of variance of new morphometric characters showed that 7 out of the 8 hind wing variables displayed statistically significant differences among populations (P < 0.05). The scatter plot from Canonical Variate Analysis revealed that th . . .e colonies from north (Ilam, Khuzestan, and Bushehr states) showed an overlapping distribution. The colonies from south (Hormuzgan state) formed a non-overlapping distant cluster. Based on the spatial autocorrelation analysis, 14 correlograms were significant for morphometric characters (According to the Bonferroni criterion). Six characters (CuB, C.Ind, HWW, B4, D7, and I13) showed clinal type correlogram. © TÜBİTAK Daha fazlası Daha az

There are twelve Microtus species in Turkey and two of them are endemic to the steppic central Anatolian plateau. In this study, previously collected specimens that were recorded as Microtus irani from southeastern Turkey were reevaluated by karyologically comparing different species distributed throughout southeastern Turkey. The taxonomic status of this species was raised to a new species, Microtus elbeyli sp. nov., which has dark ochreous dorsal color, agrestis morphotype in M2, and 2n = 46, NF = 50, NFa = 46 karyotype. The new species described here raises the total number of Microtus species in Turkey to 13 and endemic vole spe . . .cies in Anatolia to three.

Morphological, biometrical, karyological, bacular and phallic aspects of Apodemus mystacinus populations in Turkey were studied based on 117 specimens. The biometrical and phallic comparisons confirmed the distinctness of A. m. mystacinus and A. m. epimelas. The UPGMA tree divided populations in Turkey into 2 groups. The distance (D) between A. m. mystacinus and A. m. euxinus was 0.469. A. mystacinus had karyotypic values of 2n = 48, NFa = 50, and NF = 52. Being different from A. m. epimelas, there was a short groove in the dorsal view of the phallus in populations of A. m. mystacinus in Turkey. © TÜBİTAK.

Field and laboratory investigations on the ecology, reproduction and behavior of Spermophilus citellus and Spermophilus xantophrymnus were performed over a period of 4 years. Both S. citellus and S. xanthophrymnus are diurnal species and occupy semiarid steppe areas in Turkish Thrace and Anatolia, respectively. Distribution of the former species is confined to restricted steppe areas in Turkish Thrace whilethe, latter lives on the Anatolian steppe, and is sympatric with Meriones tristami, Mesocricetus brandthi, Allactaga williamsi and Microtus spp. The burrows of both species have one entrance, and are built separately in the field. . . . They constitute small social colonies and communicate with each other by emitting hoarse, sharp and shrill sounds. S. xantophrymnus enterrs hibernation in August and emerges in February. It was observed that they were tolerant of each other. Based on field and laboratory studies S. citellus and S. xantophrymnus give birth once a year. The litter size was at 3 for the former species, and 1-4 for the latter. Average weight at birth was 5 g for both species. Newborns of both species became hairy at 15-17 days, their eyes opened at 22-25 days, and their ears at 30 days and offspring were weaned at the end of the second month after birth. The external characters of 2 babies from Edirne attaned those of adults 4 months after birth. © TÜBİTAK Daha fazlası Daha az

Talpa davidiana is the least known species of the genus Talpa, and the karyotype of this species is still unknown. Its distribution records are also very scattered. The karyological, cranial, and pelvic characteristics of 2 samples from Kızıldağ in Adana Province were analyzed for the first time. It was determined that T. davidiana has 2n = 34, NF = 66, and NFa = 62. The X chromosome was large and metacentric and the Y chromosome was dot-like acrocentric. The 2 samples are different from each other, and from previous T. davidiana records, in terms of their lower incisor and premolar numbers. Unique among the T. davidiana samples exa . . .mined to date, 1 of the samples studied here had 2 premolars on the lower jaw half instead of 3. In contrast to the literature, 1 sample has a europeoidal pelvis, and the other has an intermediate form. T. davidiana has been recorded from 6 localities from the area between Hakkari and Gaziantep provinces in Turkey. The Kızıldağ high plateau of Adana was a new distribution locality and the most western for T. davidiana. The nearest known locality is Meydanakbes village, and it is almost 160 km away, as the bird flies, from Kızıldağ high plateau. The new distribution record from Kızıldağ high plateau implies that the mountain range between Tatvan and Adana may include some undiscovered samples.

Makale | 2017 | Turkish Journal of Zoology41 ( 6 ) , pp.1059 - 1068

Acomys cilicicus is endemic to Turkey and known from a very restricted area. The exact distribution of the species was not known up to now and the IUCN status of the species was Data Deficient (DD). To determine the exact distribution area of the species, 39 localities within the historical distribution were surveyed by using 3243 Sherman traps between 2013 and 2016. Turkish spiny mouse samples were obtained from 14 of these 39 localities and the current distribution of the species was determined. We found that the Turkish spiny mouse has two isolated populations in the area between Silifke and Erdemli with a total distribution area . . . of about 104.5 km2, extending from sea level up to 510 m a.s.l. Population trend estimates showed a steep decline in the last 20 years from 21.42 to 2.75 as trap night index value. These data, along with the decline in habitat quality and continuing threats to the species, merit an IUCN status of Critically Endangered (CR). The main threats for this species are habitat loss due to urbanization, new motorway construction, stone quarry development, conversion of Mediterranean shrublands into agricultural fields, and afforestation. For conservation purposes, a species protection action plan is necessary immediately. © TÜBİTAK Daha fazlası Daha az

Endoparazitoid zarkanatlı türü, Pimpla turionellae L., kimyasal yapısı bilinen sentetik besin ortamlarında aseptik şartlarda beslenerek, farklı yapı ve etkiye sahip onüç antimikrobiyal ajanın böceğin yaşama ve gelişmesine etkileri incelendi. Bu etkiler denenen antimikrobiyal ajanın çeşidine ve miktarına göre değişmektedir. Denenen ajanların etkileri çoğunlukla larva sonrası evrelerde ortaya çıkmış olup bu evrelerdeki yaşama ve gelişme olumsuz yönde etkilenmiştir. Antimikrobiyal ajanlar aynı zamanda larval evredeki gelişmeyi de etkilemiş ancak bu evredeki yaıama üzerinde önemli bir etki yapmamıştır. Larvalar antimikrobiyal ajanların . . .hem çeşidine hem de besinsel miktarına karşı geniş bir tolerans göstermiştir. Denenen ajanların hiçbiri larvalar üzerinde toksik etki yapmam ıştır. Sodyum benzoat ve nistatinin düüşk miktarları larvaların besin tüketimine olumlu etkide bulunmuştur. The effects of 13 antimicrobial agents that have different structures and modes of action, on the survival and development of the hymenopterous endoparasitoid, Pimpla turionellae L., were investigated by rearing the larvae aseptically on chemically defined synthetic diets. These effects varied according to their kind and dietary levels. The agents tested exerted their effects generally during the post-larval development of the insect. The post-larval survival and development were negatively affected by most of the agents tested at certain levels. The antimicrobial agents tested also affected the larval development but had no significant effects on the larval survival of the insect. The larvae showed a wide tolerance against both the kind and dietary levels of the agents. None of the agents tested were toxic to the larvae. Sodium benzoate and nystatin at low levels had positive effects on the food consumption of the larv Daha fazlası Daha az
