Göller bölgesi Emys orbicularis (Testudinata: Cryptodira: Emydidae) populasyonunda biyolojik ve ekolojik gözlemler

Bu çalışmada, Nisan 2001 ve Temmuz 2002 tarihleri arasında Göller Bölgesi ve civarında sekiz lokalitede Emys orbicularis’in biyolojisi ve ekolojisi üzerine bazı gözlemler ve yaşadıkları biotoplara ait bazı fiziksel parametreler verilmiş ve elde edilen veriler literatür bilgisi ile karşılaştırılmıştır. Beş örnekte sindirim sistemi içeriği incelenmiş, toplam 35 omurgasız av teşhis edilmiş ve bunun yanında çok sayıda bitkisel materyal de gözlemlenmiştir. Çalışma alanlarında türün çiftleşme davranışları Mayıs-Haziran ayları arasında gözlenmiş, ayrıca temmuz ayında yuvaya bırakılmış yumurtalara ve yumurtadan yeni çıkmış örneklere de rastlanmıştır. Temiz su indikatörü olarak bilinen türün, yapılan çalışmalarla antropojen kaynaklı atık sularda da yaşadığı tespit edilmiştir.

Biological and ecological observations on Emys orbicularis (Testudinata: Cryptodira: Emydidae) population from the Lakes District

Biological and ecological observations on Emys orbicularis (Testudinata: Cryptodira: Emydidae) population from the Lakes District. In this study, conducted between April 2001 and July 2002, some observations were made on Emys orbicularis from eight different localities at and in the vicinity of the Lakes District, also some physical parameters on their habitats were given. The obtained data were compared with those given in relevant literature. Gut contents in five specimens were analysed and a total of 35 invertebrate preys were determined, also a lot of plant material was observed. The breeding behavior of the species was observed within the study area in May and June, in July eggs were observed in nests, also some newly hatched nestlings. The presence of the species, which is known as a clear water indicator, also in antropogenous waste waters was established.
