Öğe Contribution to Rousettus aegyptiacus (Mammalia : chiroptera) from Turkey(INST VERTEBRATE BIOLOGY AS CR, 2003) Karatas, A; Yigit, N; Colak, E; Kankilic, TRousettus aegyptiacus is active throughout the year in Turkey, where its morphology was studied collected from three localities in the south-west. The characteristics of the Turkish population were similar to those of the nominative subspecies. Moderate differences between the sexes were found in tibia length and total body length. The karyotype is 2n=36, FN=70, FNa=66. The X chromosome is a large metacentric/submetacentric, and the Y chromosome is a dot-like acrocentric.Öğe Histo-anatomical studies on the accessory reproductive glands of the Anatolian souslik (Spermophilus xanthoprymnus) (Mammalia : Sciuridae)(WILEY, 2004) Cakir, M; Karatas, AIn this study, the histo-anatomy of the accessory reproductive glands of the Anatolian souslik (Spermophilus xanthoprymnus) is investigated, using 102 males of the vouchers which were captured from central Anatolia and eastern Mediterranean regions. Averages of measurements taken from each part of the accessory reproductive glands were as follows: length of vesicular gland [right: 3.96 (+/-0.48) mm; left: 3.70 (+/-0.55) mm]; prostate gland [length: 2.55 (+/-0.38) mm; width: 2.63 (+/-0.45) mm]; length of bulbourethral gland [right: 2.32 (+/-0.33) mm; left: 2.37 (+/-0.39) mm], and the length of the pars pelvina of the urethra was 12.31 (+/-0.76) mm. Histological sections showed that vesicular gland was composed of typically branched tubulo-alveolar glands. As the fibrous connective tissue that was found among alveoles in the prostate was dense and relatively common, only few tubulo-alveolar glands occurred. The bulbourethral gland (Cowper's gland) was a tubulo-alveolar gland with a large and serrated lumen and septa between the alveoles consisted of dense fibro-muscular fibres.Öğe Karyotogy of some bat species (Chiroptera : Rhinotophidae, Molossidae) from Turkey(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2006) Karatas, A; Sozen, M; Matur, F[Abstract Not Available]Öğe Mitochondrial phylogeography of the long-eared bats (Plecotus) in the Mediterranean Palaearctic and Atlantic Islands(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004) Juste, J; Ibanez, C; Munoz, J; Trujillo, D; Benda, P; Karatas, A; Ruedi, MLong-eared bats of the genus Plecotus are widespread and common over most of the western Palaearctic. Based on recent molecular evidence, they proved to represent a complex of several cryptic species, with three new species being described from Europe in 2002. Evolutionary relationships among the different lineages are still fragmentary because of the limited geographic coverage of previous studies. Here we analyze Plecotus mitochondrial DNA sequences from the entire Mediterranean region and Atlantic Islands. Phylogenetic reconstructions group these western Palaearctic Plecotus into two major clades which split at least 5 Myr ago and that are each subdivided into further subgroups. An 'auritus group' includes the traditional P. auritus species and its sister taxon P. macrobullaris (= P. alpinus) plus related specimens from the Middle East. P. auritus and P. macrobullaris have broadly overlapping distributions in Europe, although the latter is apparently more restricted to mountain ranges. The other major clade, the 'austriacus group' includes the European species P. austriacus and at least two other related taxa from North Africa (including P. teneriffae from the Canary Islands), the Balkans and Anatolia (P. kolombatovici). The sister species of this 'austriacus group' is P. balensis, an Ethiopian endemic. Phylogenetic reconstructions further suggest that P. austriacus reached Madeira during its relatively recent westwards expansion through Europe, while the Canary Islands were colonized by a North African ancestor. Although colonization of the two groups of Atlantic Islands by Plecotus bats followed very distinct routes, neither involved lineages from the 'auritus group.' Furthermore, the Strait of Gibraltar perfectly segregates the distinct lineages, which confirms its key role as a geographic barrier. This study also stresses the biogeographical importance of the Mediterranean region, and particularly of North Africa, in understanding the evolution of the western Palaearctic biotas.

We studied the genetic differentiation and taxonomy of this species in the transition zone between south-eastern Europe and Anatolia (in Asia), where two subspecies have been described. The results indicated a sharp genetic break between the samples from western Anatolia and south-eastern Europe and those of eastern Anatolia. In addition, the samples from western Anatolia and south-eastern Europe were seen to be reciprocally monophyletic, although the differentiation was less drastic. These patterns of genetic differentiation suggest the presence of two distinct groups within the M. schreibersii complex in the region, concordant with previous subspecific recognition. The cause of this genetic break is most likely differentiation in separate glacial refugia followed by secondary contact. However, more samples are needed to assess whether these represent different species, as well as to understand more clearly the causes of this differentiation.

The phylogenetic analysis performed showed their affinities to the European species E. gamma and E. germanus, but not to the E. carpathicus complex.
