Abstract
<p>In this study, we focused on the prey animals of two top-predator, endangered, umbrella species of Iriomote-jimaIsland, the Iriomote cat and the crested serpent eagle. The effective conservation of their habitats is necessary tomaintain and conserve the entire ecosystem of this island. We carried out a detailed analysis of their diets using theDNA barcoding method, a popular method to analyze wild animal diets. The predator animal feces were collected inwinter and summer, and tried to identify their prey species based on the sequence similarity of extracted fecal DNA.We identified a higher number of prey species than those from a past study and showed the effectiveness of thismethod in analyzing wild-animal diets. Both species were found to prey on multifarious species, for example, frogs,skinks, rat, birds, Sesarmops intermedium, and Scolopendra subspinipes mutilans. Thus, we must maintain diversity,number of individuals, and biomass of these prey animals for conservation of these two predator species.</p>
