摘要: We examined the raccoon dog’s Nyctereutes procyonoides (Gray, 1834) diet in two agricultural landscapes of Germany and compared these results with other studies from its native introduced ranges. The composition was influenced as well by landscape structures seasons: waterrich study area 2 amphibians (54.1%) fish (10.8%) occurred more frequently samples. In 1 (19.0%) invertebrates (69.4%) gained significance summer, whereas winter samples maize (32.8%) an important food item. shifted according to availability different items. Raccoon dogs, ability feed temporarily on one source may possibly cause a serious problem endangered small populations birds amphibians. review 81 data sets nine countries showed that seasons locality affected occurrence most However, comparable present study, mammals, insects plants were identified items both ranges dog. regard composition, gathering foraging strategy inactivity during winter, dog probably preys less often game animals than red fox Vulpes vulpes.
