Prevalence of and Assessment of Some Risk Factors in (Valenciennes, 1833) Freshwater Turtles (Testudines: Geoemydidae).

Objective: The Balkan terrapin, , is a freshwater turtle. This reptile is exposed to many environmental pollutants and some infectious agents, including parasite. This study was conducted to determine the microscopic prevalence of haemogregarine infection in caught in three different localities (Bozcaada, Gökçeada, and Dardanos) in Çanakkale province of Turkey, and assessment of some risk factors.

Determination of the effects of environmental pollution on the Balkan terrapin, Mauremys rivulata (Valenciennes, 1833).

The effects of environmental pollution on three populations of the Balkan terrapin [Mauremys rivulata (Valenciennes, 1833)] from the Bozcaada, Gökçeada and Dardanos regions were evaluated. The morphological parameters of Balkan terrapins collected on each site were measured and blood samples were taken for haematological analysis and micronucleus detection. The physicochemical, microbiological and microelement analyses of the water samples from each region were conducted by standard methods.
