Abstract

We investigated breeding biology of Common coot (Fulica atraL. 1758) in the Lake Kovada between April 2012 and July 2013. The minimum clutch size was determined in station III and the maximum in station I. and II. Clutch size of the species in 32 nests changed between 1-9 eggs and total 179 eggs were counted in the study 89 were observed in station I, 83 in the station II and 7 in the station III. Nest preference of the species was determined as 53.1% for the station I. However, we determined clutch size and nest volume increased proportional to the distance from the main road (p<0,01). During the study, we did not observe any threat factors directly affecting the species in the area. However, we hope that population features will be optimized by conservative actions in the future

Kovada Gölü (Isparta) Sakar Meke (Fulica atra L. 1758) Populasyonunun Üreme Biyolojisi

Abstract

2012-2013 döneminde, Kovada Gölü'nde sakar mekenin (Fulica atra L. 1758) biyolojisi incelenmiştir. Kuluçka büyüklüğü III istasyonda en az, I ve II. istasyonlarda en fazladır. Kuluçka büyüklüğü 1-9 arasında değişmekte olup 32 yuvada; 89'u I. istasyonda, 83'ü II. istasyonda ve 7'si III. istasyonda toplam 179 yumurta sayılmıştır. Tür üreme alanı olarak I. istasyonu % 53,1 oranında tercih etmiştir. Ayrıca yumurta sayısı ve yuva hacminin karayolundan uzaklaştıkça arttığı tespit edilmiştir (p<0,01). Alanda çalışma boyunca türü doğrudan etkileyen tehdit belirlenememiştir. Ancak alınacak koruyucu tedbirlerle populasyon özelliklerinin iyileşeceği düşünülmektedir.
