Çubuk Çayında Ankara Bentik Makro Omurgasızların Yapısı

Öz

Bu çal ışmada Çubuk Çayı 'ndaki Ankara organik kirlenmeye ba ğ l ı olarak bentik makro omurgas ı zlar ı n organizma çeşitliliği ve bolluk durumu incelenmi ştir. Araşt ı rmada Tubificidae Annelidae , Chironomidae Diptera , Erpobdellidae Hirudinea , Planorbidae Mollusca ve Lymnaeidae Mollusca familyalar ı na ait bireyler bulunmu ştur. Bu organizmaları n çeşitliliğ i ve bolluğ u örnekleme noktalar ı na ve mevsimlere bağ l ı değ i şim göstermi ştir. Organik kirlenmeye karşı toleransl ı olan ve indikatör olarak değ erlendirilen Annelidae ve Diptera gibi organizma gruplar ı n ı n bollukları n ı n artmas ı ve genel olarak organizma çeşitliliğ inin azalmas ı gibi durumlar kirlilik düzeyine ba ğl ı bir reaksiyon olarak gelişmiştir. Bu durum özellikle mezbaha ç ı kışı n ı n olduğ u bölgede Tubificidae bollu ğu: %100 gözlenmi ştir.

The Structure of Benthic Macro Invertebrate in Çubuk River Ankara

Abstract

The diversity and abundance of benthic macro invertebrates in relation to organic pollution in Çubuk river Ankara were investigated The individuals of families Tubificidae Annelidae , Chironomidae Diptera , Erpobdellidae Hirudinea , Planorbidae Mollusca and Lymnaeidae Mollusca were identified in the study. The diversity and abundance of these organisms were changed throughout the seasons and the sampling locations. An increase in the abundance of the tolerant organisms against organic pollution and evaluated as an indicator such as Tubificidae and Chironomidae and in general, the decrease of organisms diversity occured as a response to pollution level. This situation, particularly was observed in the discharge of slaughter houses region The abundance of Tubificidae: 100%
