Sažetak
No previous field investigation on biology and ecology of a native population of golden jackals (Canis aureus L.) from Dalmatia has been conducted. The objective of this study was to detect the feeding habits of this poorly studied population. The diet composition of golden jackals from Dalmatia was examined by scat analysis. From winter 1995 to spring 1997, field visits were made every season to the golden jackal habitat on the Pelješac Peninsula in Dalmatia, Croatia and scats of golden jackals were collected (n=130). Scats were washed out, dried and sorted. Classification of components was made under appropriate magnification. Both animal and plant components were found. Scat included from one to four components. The highest frequency was found for mammals (50.3%) followed by fruit seeds and vegetables (34.1%), insects (29.5%), birds (including eggs) (24.8%), artificial materials (24%), branches, leaves and grass (24%). In scats containing mammal remains, the highest incidence was for large mammals (unidentified large mammals and mammals of the order Artiodactyla and Lagomorpha). Small mammals were found but in a negligible frequency. Most important fruits for jackals are Ficus carica L. (14%), Vitis vinifera L. (14%) and Juniperus oxicedrus L. (4.6%). The most important orders of insects are Orthoptera (16%), Coleoptera (12%) and Dyctioptera (3%), and for birds order Charadriiformes (6%). The negligible amount of small mammals found in scats differ from the most investigations made elsewhere. The results show the close relation of the population with human settlements and regional agricultural habits .
