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 Jan 1999

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 Jan 1999

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 …

Taxsonomical States Of Lacerta Viridis (Lacertidae) Populations From Turkey, İ. Ethem Çevi̇k, Yusuf Kumlutaş

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.

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.

Live weights of Bronze turkeys reared in intensive and semi-intensive conditions (male+female) were found as; 4273.8±95.5 g and 4185.0±107 g at the end of 16. weeks, respectively. Difference between the mean weights was not significant (P>0.05). Turkeys reared on floor were consumed more feed than the other group. Cumulative feed consumptions of turkeys reared in intensive and semi-intensive conditions were determined as 13562.0±50.0 g and 12415.0±100.0 g at the end of 16. weeks, respectively. Difference between these values …
