Abstract

Zlatni čagalj (Canis aureus Linneaus, 1758) je najveća i prostorno najraširenija vrsta čaglja te jedina koja se može pronaći izvan Afrike. Srednje veliki je sisavac koji pripada porodici pasa (Canidae) i redu zvijeri (Carnivora). Posljednjih godina, čagalj se naglo proširio Europom te formirao stabilne populacije uz najveću gustoću na području istočnog i središnjeg Balkana. Hrvatsku nastanjuje podvrsta europsko-maloazijski čagalj (Canis aureus moreoticus I. Geofrry Saint-Hilaire, 1835) koji se u najvećoj brojnosti može pronaći na sjeveru i jugu Dalmacije te u istočnoj Hrvatskoj. Čagalj je karnivor, no prema načinu života smatra se oportunistom i omnivorom koji prednost mahom daje najlakše dostupnoj hrani. Primarno jede hranu životinjskog podrijetla, no važan dio prehrana mu čine i biljne vrste te strvine. Prilagođen je različitim tipovima staništa, pa i ona u blizini ljudskih naselja, no u pravilu izbjegava staništa koje naseljava vuk. Čagalj ponekad dijeli staništa s drugim karnivorima koji imaju potrebe za sličnim resursima. Najčešće su to lisica, ris i vuk s kojima onda ulazi u različite interspecijske interakcije kao što su kompeticija i koegzistencija.

Abstract (english)

The golden jackal (Canis aureus Linnaeus, 1758) is the largest and most widely distributed species of jackals and the only one that can be found outside Africa. It is a medium-sized mammal that belongs to the family of dogs (Canidae) and the order of beasts (Carnivora). In recent years, jackals have rapidly spread across Europe and formed stable populations with the highest density in the area of the eastern and central Balkans. Croatia is inhibited by the subspecies of the European jackal (Canis aureus moreoticus I. Geofrry Saint-Hilaire, 1835), which can be found in highest population density in the north and south of Dalmatia and in eastern Croatia. Jackal is a carnivore, but according to its lifestyle, it is considered an opportunist and an omnivore, which generally prefers the most readily available food. Its primarily food source is of animal origin, but an important part of its diet are also plant species and carrion. Jackals are adapted to different types of habitats, including those near human settlements, but it generally avoids habitats inhabited by wolves. Jackals can share habitats with other carnivores that have similar resource needs. Most often foxes, lynxes and wolves, with which various interspecies interactions take place such as competition and coexistence.
