Isolation Of Sperm Storage Tubules From The Uterovaginal Junction Mucosa Of The Turkey, L. M. King, J. P. Brillard, M. R. Bakst, A. M. Donoghue
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
This study was performed to determine whether intact sperm storage tubules (SST) could be successfully isolated from the uterovaginal junction (UVJ) mucosa of the turkey. Large White BUTA hens were inseminated and euthanatized 24 to 48 h later. Oviducts were excised, UVJ tissue removed, and SST were procured by enzymatic digestion. Recovered SST were intact and contained motile sperm. The sperm were oriented with their acrosomes pointed towards the distal end of the SST, and their long axes in parallel with the long axis of the tubule’s lumen. This method for the isolation of intact SST can be readily applied …

The Distribution Problem Of Crocidura Russula (Hermann, 1780) (Mammalia: Insectivora) In Turkey, Haluk Kefeli̇oğlu, Coşkun Tez
Turkish Journal of Zoology
In this study, to elucidate distribution problem of Crocidura russula (Hermann, 1780) species, 298 samples were taken from different geographical areas, type localities and record areas of Turkey, which were morphologically similar to C. russula were studied. The karyotypical and morphological characteristics of collected samples have been examined in detail. Those examined characteristics have been compared among themselves and compared to literature data. According to the comparative results, C. russula species is not distributed in Turkey and the Populations of C. russula reported previously in Turkey were belong to Crocidura suaveolens (Pallas, 1811).
A Study Of The Taxonomy And Karyology Of Meriones Persicus (Blanford, 1875) (Mammalia: Rodentia) In Turkey, Nuri̇ Yi̇ği̇t, Ercüment Çolak
A Study Of The Taxonomy And Karyology Of Meriones Persicus (Blanford, 1875) (Mammalia: Rodentia) In Turkey, Nuri̇ Yi̇ği̇t, Ercüment Çolak
Turkish Journal of Zoology
In this study, three live specimens captured around Oltu ( Erzurum ) were examined in terms of their morphological and karyological features. The diploid number of the chromosomes was 2n= 42, the fundamental number FN= 78 and the number of autosomal arms was FNa= 74. The X and Y chromosomes were both submetacentric in M. persicus. It was determined that the small white supraorbital spot found between the eyes and ears of the pelage, as well as karyological traits, distinguish Meriones persicus from Meriones tristrami. On the basis of morphological similarity, it was concluded that these taxa were sibling species.

Morphological And Taxonomical Investigations On The Genus Of Epidinium Crawley, 1923 (Protozoa: Ciliophora: Entodiniomorphida), Bayram Göçmen
Morphological And Taxonomical Investigations On The Genus Of Epidinium Crawley, 1923 (Protozoa: Ciliophora: Entodiniomorphida), Bayram Göçmen
Turkish Journal of Zoology
Rumen contents obtained from 30 domesticated cattle (Bos taurus L.), slaughtered at abattoirs in the vicinity of Izmir, were surveyed for ciliates belonging to the genus of Epidinium. Results of this survey suggested that the ciliates in the genus should not be classified to the species level on the basis of caudal spination characteristics, as previously proposed (1). Populations intermediate in these characteristics were detected in Turkish cattle and analysis of the morphometrical data for all criteria did not indicate significant differences for establishing separate species. It appears that these features, which show continuous variation, are more appropriate for classification …

Morphological And Taxonomical Investigations On The Genus Of Ophryoscolex Stein, 1858 (Protozoa: Ciliophora: Entodiniomorphida), Bayram Göçmen
Turkish Journal of Zoology
Rumen contents obtained from 30 domesticated cattle (Bos taurus L.), slaughtered at abattoirs in the vicinity of Izmir, were surveyed for ciliates belonging to the genus of Ophryoscolex. Results of this survey suggested that the ciliates in this two genus should not be classified to the species level on the basis of caudal spination characteristics or the number of the rings of secondary caudal spines, as previously proposed (1, 2). Populations intermediate in these characteristics were detected in Turkish cattle and analysis of the morphometrical data for all criteria did not indicate significant differences for establishing separate species. It appears …

Turkish Journal of Veterinary & Animal Sciences
This study was carried out to determine the prevalence of liver fluke infections in cattle and sheep in Trakya (The European Part of Turkey). For this purpose the slaughterhouses of different localities (Tekirdağ, Hadimköy, Lüleburgaz, Çorlu, Kırklareli and Keşan) were visited between 03.03.1997 and 22.10.1997, and a total of 476 sheep and 415 cattle livers were examined. The prevalence rates of fasciolosis hepatica and dicrocoeliosis dendriticum were 3.99% and 23.55% in sheep, and 0.48% and 2.65% in cattle respectively. No changes in livers, which led to the partial or total condemnation, were observed.

Turkish Journal of Zoology
In this research, , A total of 64 MM and 37 VV adult specimens from Turkish Thrace and 158 MM and 188 VV adult specimens from Anatolia were investigated comparatively as two separate populations groups to determine the subspecific status of the species in Turkey. No significant differences are discernible between the two population groups from the viewpoints of pholidosis, morphometrical measurements and rations and pattern and coloration characteıistics. So the Turkish L. viridis populations belong to a single subspecies L. v. meridionalis.

The Taurus mountains area is one of the most interesting areas of Turkey as regards flora and vegetation. The region is situated on a transition zone between the Mediterranean and continental climate and contains many microclimate areas because of its topographic character. Therefore, studies on the flora and vegetation of the Taurus mountains give quite different results. The studies on the catchment area of Göksu valley and environs which exhibit Mediterranean climate and is a part of the central Tauruses were ccarried out in 1995-1996. In this study, Braun-Blanquet's floristic system principle was used and six associations (five of them …
