    The Ciliate Fauna in the Digestive System of Rana Ridibunda (Amphibia: Anura) I: Balantidium (Balantidiidae, Trichostomatida)
    (2000) Şenler, N.G.; Yildiz, I.
    Balantidium spp. living in the digestive system of Rana ridibunda in Van were determined. Five species belonging to the genus Balantidium were distinguished. Of these, one new species was recognized, described as Balantidium vanensis n. sp. This study reports for the first time the presence of B. helenae, B. claperedei and B. giganteum in the digestive system of R. ridibunda. These species are also new records for the protozoan fauna of Turkey. There was only B. duodeni in the duodenum and B. elongatum in the intestinal part next to the duodenum. The species of the genus Balantidium in the rectum constituted 50.21% of B. helenae, 28.41% of B. claperedei, 9.06% of B. vanensis, 7.16% B. elongatum and 4.98% of B. giganteum. The species determined in the study were compared with the available information in the original descriptions and the previous reports and the similarities and differences were discussed. It was determined that the digestive system microfauna of the genus Balantidium from R. ridibunda in Van is similar to the fauna of Asiatic frogs in terms of diversity.

    Faunistic and Morphological Studies on Ciliates (Protozoa, Ciliophora) From a Small Pond, With Responses of Ciliate Populations To Changing Environmental Conditions
    (2004) Şenler, N.G.; Yildiz, I.
    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. © TÜBITAK.
