The oligochaeta (Annelida) fauna of Topçam Dam-Lake (Aydin, Turkey)

With the aim of identifying the oligochaeta fauna of Topçam Dam-Lake, located on the north-western slopes of the East Menteşe Mountains (Aegean region, Turkey), a number of samples were collected monthly between June 1999 and June 2000. Having no previous faunistic studies, some physico-chemical features and oligochaeta fauna of the dam-lake were determined for the first time in this research. Consequently, 11 species were determined, 9 species from Tubificidae, and 2 species from Naididae. Tubificid Limnodrilus hoffmeisteri was the dominant Oligochaeta species and represented 64.64% of the total Oligochaeta community in the dam-lake. There are almost no data on the Oligochaeta fauna of this region so far. Hence, all the determined taxa from the localities are recorded for the first time. © TÜBİTAK
