“…Rodents, carrion (especially innards and the leftovers from game hunting), vegetable matter (e.g., fruits and maize from bait stations) are presumed to be abundant in most months. Furthermore, the red fox is a more active predator and consumes more vertebrates (mammals and birds) than the raccoon dog, which feeds frequently on shrews, invertebrates, carrion and plants (Goldyn et al 2003;Kauhala and Auniola 2001;Sidorovich et al 2000;Sutor et al 2010). Competition for resources between the species is eased by their omnivorous character (Viro and Mikkola 1981) as well as these dietary differences.…”

“…Diet analyses show that both red foxes and raccoon dogs are true opportunists and generalists (Ansorge 1991;Cavallini and Volpi 1996;Ansorge 1998;Drygala et al 2000;Goldyn et al 2003;Sutor et al 2010), and food niche overlap studies indicate that these canids can coexist (Jędrzejewska and Jędrzejewski 1998;Kauhala et al 1998). Our main objective, then, using very high frequency (VHF) radio telemetry, was to shed light on interference and/or exploitative competition between these two canids in the intensively used agricultural landscape of northeast Germany (Mecklenburg-Western Pomerania).…”

The main objective was to discover extent of interference and/or exploitative competition between the native red fox (Vulpes vulpes) and the introduced, invasive raccoon dog (Nyctereues proconoides) in the intensively used, agricultural landscape of northeast Germany (Mecklenburg-Western Pomerania) using very high frequency (VHF) radio telemetry. We recorded location data for 12 foxes and 16 raccoon dogs between July 2004 and December 2006. Species had similar average home range sizes estimated in each season (K95). Home ranges of adjacent raccoon dogs and foxes overlapped from 0.5 to 74.5 % with a mean of 26.4 %. We found a significantly different home range overlap index between the species showing that raccoon dog ranges shifted between seasons to a greater extent than red fox ranges. The raccoon dog differed significantly from the red fox in its use of habitat types, preferring dense vegetation cover and avoiding open areas. The red fox displayed less preference for or avoidance of specific habitat types. Moreover, an almost neutral inter-specific interaction index ranging from −0.12 to 0.12 indicates that raccoon dogs and red foxes ignored each other. It is concluded that widespread and available resources and differences in spatial use patterns prevent competition between red foxes and raccoon dogs in the agricultural landscape of northeast Germany.

“…Both host species are not specialized on any particular diet and are food generalists and opportunistic omnivores. In general, the fox is a more active predator and consumes more often vertebrate prey while the raccoon dog frequently eats invertebrates, carrion and plants [18][19][20][21][22].…”

“…Our raccoon dogs frequently visited farms, yards, gardens, composts, and waste heaps indicated by the occurrence of household waste (e.g., boiled meat and potatoes, imported fruits) and undigestible, man-made material in their gastrointestinal tracts. Also previous studies reported that raccoon dogs utilized compost piles and refuse dumps and that this behavior could be emphasized in winter [20,38,44-47]. In the use of anthropogenic food resources, the raccoon dog resembles several omnivorous canids and mustelids [48].…”

Application of change-point analysis to determine winter sleep patterns of the raccoon dog (Nyctereutes procyonoides) from body temperature recordings and a multi-faceted dietary and behavioral study of wintering

et al. 2012

BackgroundA multi-faceted approach was used to investigate the wintertime ecophysiology and behavioral patterns of the raccoon dog, Nyctereutes procyonoides, a suitable model for winter sleep studies. By utilizing GPS tracking, activity sensors, body temperature (Tb) recordings, change-point analysis (CPA), home range, habitat and dietary analyses, as well as fatty acid signatures (FAS), the impact of the species on wintertime food webs was assessed. The timing of passive bouts was determined with multiple methods and compared to Tb data analyzed by CPA.ResultsRaccoon dogs displayed wintertime mobility, and the home range sizes determined by GPS were similar or larger than previous estimates by radio tracking. The preferred habitats were gardens, shores, deciduous forests, and sparsely forested areas. Fields had close to neutral preference; roads and railroads were utilized as travel routes. Raccoon dogs participated actively in the food web and gained benefit from human activity. Mammals, plants, birds, and discarded fish comprised the most important dietary classes, and the consumption of fish could be detected in FAS. Ambient temperature was an important external factor influencing Tb and activity. The timing of passive periods approximated by behavioral data and by CPA shared 91% similarity.ConclusionsPassive periods can be determined with CPA from Tb recordings without the previously used time-consuming and expensive methods. It would be possible to recruit more animals by using the simple methods of data loggers and ear tags. Hunting could be used as a tool to return the ear-tagged individuals allowing the economical extension of follow-up studies. The Tb and CPA methods could be applied to other northern carnivores.
