Kırıkkale Kızılırmak’taki Su Samuru'nun Lutra lutra Biyoekolojisi

B u araştırma Eylül 2000 ile Haziran 2002 tarihleri arasında Kırıkkale ilinde Kızılırmak Nehri’ndeki iki lokalitedeki su samurlarının habitat ve beslenme özelliklerinin belirlenmesine dayanmaktadır. Su samurunun yaşam alanı içindeki yuvaları ve ayak izleri tespit edilmiş, bıraktıkları dışkılar toplanarak analiz edilmiş ve bölgenin hakim bitki örtüsünü oluşturan 64 tür bitki teşhis edilmiştir. Kızılırmak’ta su samurunun besinini oluşturan 9 balık türü saptanmıştır. İki yıldayapılan gözlemler su samurunun nispeten kirlenmemiş ırmak suyunda yaşadığını, rafineri atıklarının kirlettiği kısımlarda hiç yaşamadığını ortaya koymuştur

Bioecology of the Otter Lutra lutra in Kızılırmak River in Kırıkkale Province

This study was carried out between September 2000 and June 2002, and based on the assessment of feeding and habitat features of otter which lives in two localities with the borders of Kırıkkale provinces. The sheltering places and footprints of otter were determined and spraints collected from its territory were analyzed. Sixtyfour plant species were identified, representing the common vegetation cover in the area. Nine fish species, used as food by otter, were identified from Kızılırmak River. Observations for two years revealed that the otter live in respectively unpolluted stretches of the river whereas in the stretches from the point of refinery effluent onward.
