A study on morphological characters, spatial and seasonal densities, and co-existence of two predatory Cladocera, Cercopagis pengoi (Ostroumov, 1891) and Cornigerius meaticus (Pengo, 1879) in Lake Terkos, Turkey

Abstract

Plankton samples were collected at monthly intervals from Lake Terkos, Turkey, between April 2000 and March 2001. The numerical density of the Cladocera, Cercopagis pengoi and Cornigerius meaticus was studied according to month, season, and stations in this lake, which is a coastal lake of the Black Sea. Average densities were determined as 3789 ind/m 3 for Cercopagis pengoi and 8771 ind/m 3 for Cornigerius meaticus. The maximum level of C. pengoi was in May at 20 • C and for C. meaticus this occurred in September (18 • C). The densities of these two species vary greatly, depending on temperature. ZUSAMMENFASSUNG Von April 2000 bis März 2001 wurden monatlich Planktonproben im Terkos See (Türkei) genommen. Die Abundanzen von Cercopagis pengoi und Cornigerius meaticus wurden monatlich, jahreszeitlich und für jede Station am See gesondert bestimmt, der ein Küstensee des Schwarzen Meeres ist. Die durchschnittliche Abundanz betrug für Cercopagis pengoi 3789 ind/m 3 und für Cornigerius meaticus 8771 ind/m 3 , wobei das Maximum bei C. pengoi im Mai bei 20 • C und bei C. meaticus im September bei 18 • C erreicht wurde. Die Abundanzen beider Arten variierten beträchtlich in Abhängigkeit von der Temperatur.

“…Ancak daha sonra yapılan çalışmalarda bu türe rastlanmamıştır. Bunun dışında Alper (2004) Uluabat gölü, Aygen vd., (2012) Kaçkar dağlarındaki Büyük Kapılı Gölü, Büyükçeniz, Adalıgöl, Büyük göllerinde türle ilgili kayıt verirken, Güher, (2004) Terkos gölünde bu türün morfolojik ve ekolojik özelliklerini de incelemiştir.…”
