Abstract

<p>Raccoon dog Nyctereutes procyonoides is euryphagous animal, and could change their food-habits flexibly according to their surrounding environment. However, there were few studies which tested the flexibly focusing landscape gradients. In this study we tested the relationship between food habits of the raccoon dogs and surrounding landscape of their habitat using fecal analysis method in 7 urban parks at west region of Tokyo, Japan. We collected the droppings from each park for one year from September 2020 to October 2021 and analyzed them based on the land use of each park. Our results showed that there was positive correlation between urbanization of around the park and use of artificial resources by the raccoon dogs, and that the animals in heavily urbanized parks tended to use artificial resources through 4 seasons. These results suggested that the raccoon dogs could change their food habits according to their surrounding landscape of habitat regarding to urbanization.</p>
