Food composition of the Near Eastern Fire Salamander, Salamandra infraimmaculata Martens, 1885 (Amphibia: Urodela: Salamandridae) from Eastern Anatolia

摘要

This study presents data on the food composition of the Near Eastern Fire Salamander, Salamandra infraimmaculata, from Bingol, eastern Turkey. A total of 139 prey items was determined in the food content of 28 individuals (14 juveniles, 7 males, and 7 females). Insecta (N%= 37.4), Gastropoda (27.3%), and Isopoda (25.9%) constitute together 91% of the food items. The most frequent prey groups in the diet are Coleoptera (F%=50.0%), Isopoda (57.1%), and Gastropoda (46.4%). Coleoptera (V%= 34.6%), Gastropoda (28.0%), and Isopoda (23.5%) had the highest prey volumes. No significant difference was found between the sexes in food composition. The species generally feeds upon poorly flying or slow-moving invertebrates, but is opportunistic in taking up more mobile prey species as well. Diptera, Odonata and Hemiptera were found in small numbers only.
