英文摘要	Diet analysis is an essential part in understanding the biology of a species and functioning of ecosystems. Traditional morphological identification of undigested remains in the scats and molecular analyses of prey species' DNA have previously been used to assess diet. In the present study, caracal diet in the Abbasabad Wildlife Refuge, Central Iran, was investigated using both molecular and morphological methods. We collected 22 scat samples from caracal dens in the region. Feces were washed on sieves and their remaining components were morphologically identified. We also targeted a 307-base pair fragment of the cytochrome b gene to amplify and sequence the species' DNA. Morphological analyses revealed that 76% of the diet comprised rodent species. We identified a total of nine prey taxa using the molecular method, including six rodents, one hare, one hedgehog and one wild goat. There was a general agreement between the molecular and morphological results; however, molecular methods tended to allow a better identification of the prey species. Therefore, the DNA-based approach acts as a valuable complement to current morphological methods in the study of a rare felid's diet when no hair reference library exists.
