چکیده
Karyotype, C-banding and nucleolar organizer regions (NORs) characteristics of nine Rana ridibunda samples collected from Konya (Meram, Beyşehir, Hadim) province were examined. The diploid number of chromosomes (2n) and the fundamental number of chromosome arms (FN) were determined as 26 and 52, respectively. All of the chromosomes of this species have centromeric constitutive heterochromatin (C-band). Nucleolar organizer regions (secondary constriction) were determined on the long arm of the no. 8 submetacentric chromosome by using silver-nitrate staining technique.

Fourteen adult frogs including six banded frog, Rana camerani and eight marsh frog, Rana ridibunda ridibunda were collected from two sites of Chahar Mahal-o-Bakhtiari province at the southwest of Iran and then were examined for helminth parasites. Only Dolichosaccus rastellus (50%) was found in R. camerani, Skrjabinoeces similis (50%) and metacercarian cysts of Codonocephalus urniger (12....

A field trials were conducted to assess the helminth parasites of 12 marsh frogs (Rana ridibunda ridibunda) in the Anzali, Astara and Aghbaba regions in the north of Iran in May 1994. Experimental results showed that 83.8% of the Anzali marsh frogs were infected by one or two kinds of metacercarian cysts of digenetic trematodes. The helminth parasites were included Skrjabinoeces breviansa, S. s...

متن کاملC-Banded Karyotype and Nucleolar Organizer Regions (NORs) of Wild Boar, Sus scrofa (Artiodactyla: Suidae) from Anatolia
The present study reports the karyotype, C-banding, and nucleolar organizer regions (NORs) of 6 Sus scrofa (Linnaeus, 1758) males from Anatolia. The karyotype of S. scrofa comprised (2n) 38 chromosomes, the number of chromosomal arms (FN) was 64, and the number of autosomal arms (FNa) was 60. C-positive regions appeared to be restricted to the centromeric regions of autosomes 1, and 13-18, and ...
