Apreliminary study of the food of the dwarf snake Eirenis modestus (Martin, 1838) (Serpentes: Colubridae), in Izmir and Manisa Provinces

Bu çalışmada, İzmir ve Manisa illerinde yapılan arazi çalışmaları esnasında yakalanan 14 (4 dd, 499 ve 6juv.) Eirenis modestus örneğinin sindirim sistemi içeriği incelenmiş, toplam 44 av tespit edilmiştir. Sindirim sistemi içeriğine göre, türün besinini insecta (% 75), Chilopoda (% 11) ve Reptilia (% 2) sınıflarına ait avlar oluşturmaktadır ve geriye kalan avlar tanımlanamamıştır. Bulunma oranı bakımından Coleoptera (% 32) ve Orthoptera (% 21); görülme sıklığı bakımından Coleoptera (% 36), Orthoptera (% 36) ve Scolopendromorpha (% 29); hacim bakımından Scolopendromorpha (% 72) takımları en yüksek orana sahip av gruplarıdır. Bu sonuçlara göre, Eirenis modestus büyük oranda taş altı eklembacaklı faunası (% 86) ile beslenmektedir.

Izmir ve Manisa ili uysal yılan, Eirenis modestus (Martin, 1838) (Serpentes: Colubridae), 'ın besini üzerine bir ön çalışma

Abstract: The stomach contents of 14 (4 do", 499 and 6 juveniles) Eirenis rnodestus specimens captured during various field studies in İzmir and Manisa provinces were examined, and a total of 44 prey items were found. An analysis of the stomach contents revealed that prey belonging to the classes Insecta (75%), Chilopoda (11%), and Reptilia (2%) constituted the diet of the species; the remaining prey could not be identified. The most frequently consumed prey were the orders Coleoptera (32%) and Orthoptera (21%) by number; Coleoptera (36%), Orthoptera (36%), and Scolopendromorpha (29%) by frequency; and Scolopendromorpha (72%) by volume. Based on these results, Eirenis modestus feeds predominantly on arthropods found under stones (86%).
