Abstract

Two species of dileptid ciliates (Rimaleptus mucronatus and Rurikoplites armatus) and resting cysts in soil samples taken from natural and unnatural areas of Tekirdağ (TURKEY) were examined in terms of morphology and morphometry using standard methods. R. mucronatus is (i) a size of about 261-466 × 38–83 µm; (ii) the ratio of proboscis length to body length is 35%; (iii) dorsally located about 15 small contractile vacuoles; (iv) two types of extrusomes different in size but identical in shape; (v) about 16-22 ciliary rows; and (vi) multi-row, irregular and staggered dorsal brush, R. armatus is: (i) about 133-202 × 17-29 µm; (ii) proboscis length to body length ratio is 30% (iii) 2 contractile vacuoles dorsally; (iv) 2 types of extrusome; (v) ciliary rows, 9-12; and (vi) staggered and 2 rowed dorsal brush characterized by. R. armatus is a new record for the Turkish ciliate fauna. Resting cyst is first described in this study. The morphological features and morphometric features of R. mucronatus and R. armatus and the resting cyst morphology of R. mucronatus are similar to previously studied populations. However, the differences here may be caused by geographical region and habitat differences.

Tekirdağ Topraklarından İzole Edilen İki Dileptid Siliyat Türünün (Ciliophora, Litostomatea, Rhynchostomatia) Morfolojik Karakterizasyonu

Abstract

Tekirdağ’ın (TÜRKİYE) doğal ve doğal olmayan alanlarından alınan toprak örneklerindeki iki dileptid siliyat türü (Rimaleptus mucronatus ve Rurikoplites armatus) ve dinlenme kistleri standart yöntemler kullanılarak morfoloji ve morfometri bakımdan incelenmiştir. R. mucronatus (i) yaklaşık 261-466 × 38–83 µm büyüklüğünde; (ii) hortum uzunluğunun vücut uzunluğuna oranı %35’tir; (iii) dorsalde konumlanmış, yaklaşık 15 adet küçük kontraktil vakuol; (iv) büyüklük bakımından farklı, biçim bakımından aynı iki tip ekstruzom; (v) 16-22 sil sırası; (vi) çok sıralı, düzensiz ve atlamalı dorsal fırça, R. armatus (i) yaklaşık 133-202 × 17-29 µm büyüklüğünde; (ii) hortum uzunluğu ile vücut uzunluğu oranı %30; (iii) dorsalde 2 kontraktil vakuol; (iv) iki tip ekstruzom; (v) 9-12 sil sırası; (vi) iki sıralı ve atlamalı dorsal fırça ile karakterize edildi. R. armatus Türkiye siliyat faunası için yeni kayıttır. Dinlenme kisti ilk kez bu çalışmada tanımlanmıştır. R. mucronatus ve R. armatus’un morfolojik ve morfometrik özellikleri ile R. mucronatus’un kist morfolojisi daha önce çalışılmış popülasyonlara benzerdir. Farklılıkların coğrafik bölge ve habitat farklılığından kaynaklanabileceği düşünülmektedir.
