Turkish Journal of Zoology

The material of 31 specimens of Nannospalax ehrenbergi was collected from 11 different localities in the Hatay region in south Anatolia. The specimens were studied in respect to their morphological and karyological characteristics in detail. Some taxonomic characteristics and measurements of the body and skull were investigated. The data obtained from the specimens were compared with the results of previously published accounts and with samples collected from more than 16 other localities in Turkey, Israel, Jordan and Egypt. The karyotypes of the Yayladağ populations have 2n = 48, NF = 74 and NFa = 70, whereas the karyotypes of the …


Faunistic And Morphological Studies On Ciliates (Protozoa, Ciliophora) From A Small Pond, With Responses Of Ciliate Populations To Changing Environmental Conditions, Naci̇ye Gülkiz Şenler, İsmai̇l Yildiz Jan 2004

Faunistic And Morphological Studies On Ciliates (Protozoa, Ciliophora) From A Small Pond, With Responses Of Ciliate Populations To Changing Environmental Conditions, Naci̇ye Gülkiz Şenler, İsmai̇l Yildiz

Turkish Journal of Zoology

Sixty-nine ciliate species were identified in 19 samples from a small pond covered by Lemna minor in Van, Turkey. Statistical analysis was employed to examine the relationships between ciliates and the physical and biological parameters. Total ciliate abundance appears to be related mainly with physical and biological factors such as the dissolved oxygen in the bottom layer and the volume of Lemna and temperature in the surface layer. Some species were investigated in detail using live observation, silver impregnation, and morphometry.

Turkish Journal of Zoology

Thirty adult (16 males 14 females) Rana bedriagae caralitana specimens were investigated morphologically. According to results of the morphological analysis, the Kırkgöz (Antalya), Taşkesiği (Korkuteli/Antalya) and Girdev Plateau (Elmalı/Antalya) populations were included in Rana bedriagae caralitana. Furthermore, the distribution range of R. b. caralitana was extended to the northern part of the west Mediterranean Region.

A Morphological Study On The Venom Apparatus Of The Spider Agelena Labyrinthica (Araneae, Agelenidae), Nazi̇fe Yi̇ği̇t, Turan Güven, Abdullah Bayram, Külti̇ği̇n Çavuşoğlu

Turkish Journal of Zoology

The morphology of the venom apparatus of the spider Agelena labyrinthica was studied using scanning electron microscopy. The venom apparatus, situated in the anterior of the prosoma, is composed of a pair of chelicerae and venom glands. Each chelicera consists of two parts, a stout basal segment covered by hair, and a movable articulated fang. There are regular, parallel fine grooves on the surface of the cheliceral fang. The venom pore is situated on the subterminal portion of the fang. All of the venom glands are the same size and are shaped like long tubes. Each gland is surrounded by …

A Morphological And Taxonomical Study On The Subspecies Of The Lycian Salamander, Mertensiella Luschani, (Steindachner, 1891) (Urodela: Salamandridae), Mehmet Öz, Serdar Düşen, Mehmet Rizvan Tunç, Yusuf Kumlutaş, Hakan Durmuş, Yakup Kaska

Turkish Journal of Zoology

The morphometric measurements of 10 taxonomically important characters, and the coloration features of the 8 subspecies of Mertensiella luschani were investigated and statistical analyses were carried out. The importance of these characters in distinguishing the subspecies is discussed and some of them were found to be very reliable, although some did not show any statistical differences among the subspecies of M. luschani. The mean total body length, and the ratio of the width of the parotid to its length were the most important; the ratio of head length to head and body length, the ratio of head width to head …

Use Of Spermac® Staining Technique In The Determination Of Acrosomal Defects In Cat Semen, Alper Baran, Başak Evri̇m Şahi̇n, Mi̇that Evecen, Kamber Demi̇r, İ. Kamuran İleri̇

Turkish Journal of Veterinary & Animal Sciences

The types and rates of acrosome and other (head, mid-piece and tail) abnormal spermatozoon types were determined by the Spermac® staining technique. Semen from 5 stray tom cats under the same management conditions was used. Semen collection was performed under general anesthesia by electro-ejaculator once a week for 5 weeks. After ejaculation the semen was diluted by 100 µl of 0.9% NaCl solution and stained with Spermac® stain for morphological evaluation. The morphological criteria were acrosome, other (head, mid-piece and tail) and total morphological defect rates, and were 9.20 ± 2.55%, 9.20 ± 3.49% and 18.40 ± 4.79%, respectively. It …


Morphological And Anatomical Investigations On The Saponaria Kotschyi Boiss. (Caryophyllaceae), Ebru Ataşlar Jan 2004

Morphological And Anatomical Investigations On The Saponaria Kotschyi Boiss. (Caryophyllaceae), Ebru Ataşlar

Turkish Journal of Botany

The morphological, anatomical and micromorphological features of Saponaria kotschyi Boiss. have been studied on plants collected from Osmangazi University-Meşelik Campus, Eskişehir. S. kotschyi is an endemic species and a new record from Eskişehir. In general, the results obtained from morphological studies were consistent with the description given in the Flora of Turkey, except for the calyx, as the calyx of S. kotschyi flowers not only had glandular hairs but also eglandular hairs. The anatomical studies on cross-sections of the root, stem, leaves and surface sections of leaves were presented and compared with previous findings. Furthermore, the micromorphological properties of the …
