“…The selective mobilization of FA confirmed our previous results with C12–17 SFA, C14–17 MUFA, and C18–20 n-3 PUFA as the most preferably utilized FA during negative energy balance [23]. Also the diversity index reduced in Jan−Feb as observed previously in different parts of Europe from summer to winter [20,38-42]. Earlier fasting experiments on pigs ( Sus scrofa domestica ) showed that food deprivation of the host decreases the fecundity of roundworms [43] and, thus, the prolonged negative energy balance could have contributed to the observed decrease of intestinal helminths.…”

“…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].…”

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.

“…The spectacular raccoon dog (Nyctereutes procyonoides (Gray, 1834)) invasion of Europe in the 20th Century has so far brought concern about its possible competitive interactions with native medium-sized carnivores such as Eurasian badgers (Meles meles (L., 1758)) and red foxes (Vulpes vulpes (L., 1758)) (Kauhala 1995(Kauhala , 1996 and its potentially detrimental predation on native fauna Kauhala 1996;Sidorovich et al 2008). Raccoon dogs were introduced to the European part of the former Soviet Union between 1928 and 1955, and successfully expanded into central and northern Europe (Nowak and Pielowski 1964).…”

Based on radio-tracking of Eurasian badgers (Meles meles (L., 1758)), red foxes (Vulpes vulpes (L., 1758)), and raccoon dogs (Nyctereutes procyonoides (Gray, 1834)) and observations at burrows conducted in Białowieża Primeval Forest (eastern Poland) in 1996-2002, we addressed the hypothesis that facilitative interactions between a native (badger) and an alien (raccoon dog) species contributed to the invasion success of the latter. In winter, 88% of badger setts were occupied by both badgers and raccoon dogs, 4% by badgers and red foxes, and 4% by all three species. In summer, only 20% of badger setts were cohabited by other carnivore species (10% by raccoon dogs and 10% by foxes). Duration of occupation of badger setts by raccoon dogs averaged 117 days (SE = 21 days). Seasonal variation in raccoon dog use of badger setts was explained by changes in ambient temperature: the lower was the temperature, the higher was the rate of sett occupation by raccoon dogs. When wintering in the same sett, badgers and raccoon dogs used different parts of the sett. We conclude that facilitation by badgers (through habitat amelioration and refuge from cold and predation) makes the realized niche of raccoon dogs larger than predicted from their fundamental niche. The facilitating role of badger is stronger in winter, which is a critical period for raccoon dog survival in the temperate and boreal zone.Résumé : À l'aide de données obtenues par pistage radioélectrique de blaireaux (Meles meles (L., 1758)), de renards roux (Vulpes vulpes (L., 1758)) et de chiens viverrins (Nyctereutes procyonoides (Gray, 1834)), et d'observations des terriers dans la forêt ancienne de Białowieża (Pologne orientale) en 1996-2002, nous avons testé l'hypothèse selon laquelle les interactions de facilitation entre une espèce indigène (blaireau) et une espèce étrangère (le chien viverrin) ont favorisé le succès de l'invasion par cette dernière. En hiver, 88 % des terriers de blaireaux sont occupés à la fois par des blaireaux et des chiens viverrins, 4 % par des blaireaux et des renards roux et 4 % par les trois espèces ensemble. En été, seulement 20 % des terriers de blaireaux sont utilisés aussi par d'autres espèces de carnivores (10 % par des chiens viverrins et 10 % par des renards). L'occupation des terriers de blaireaux par les chiens viverrins dure en moyenne 117 jours (ET = 21 jours). La variation saisonnière de l'utilisation des terriers de blaireaux par les chiens viverrins s'explique par les changements de température ambiante; plus la température est basse, plus de taux d'occupation des terriers par les chiens viverrins est éle-vée. Lorsqu'ils passent l'hiver dans un même terrier, les blaireaux et les chiens viverrins utilisent des sections différentes. Nous concluons que la facilitation par les blaireaux (par amélioration de l'habitat et fourniture d'un refuge contre le froid et la prédation) rend la niche réalisée des chiens viverrins plus large qu'on ne pourrait le prédire à partir de leur niche fondamentale.

“…They are characterized by high reproductive capacity (Helle and Kauhala 1995;Kowalczyk et al 2009) and high food habit plasticity (Kauhala 1996;Jędrzejewska and Jędrzejewski 1998). Raccoon dogs are omnivorous carnivores and their diet strongly varies between different locations Jędrzejewska and Jędrzejewski 1998;Drygala et al 2000;Sidorovich et al 2000Sidorovich et al , 2008.

Based on radio-tracking of raccoon dogs Nyctereutes procyonoides in Białowieża Primeval Forest (E Poland) in 1997-2002, we addressed the hypothesis that pattern of shelter use by this invasive carnivore is an adaptation to both climatic conditions and predation. Raccoon dogs used various types of shelters but were invariably concealed in dense vegetation or in the shelters created by trunks, branches, or roots of fallen trees (58% of days). Burrows (mainly badger setts) and hollow trees (mainly fallen limes) were selected on 27% and 14% of days, respectively. The pattern of shelter use varied throughout the year. In crucial periods (breeding period and winter), raccoon dogs used shelter offering better protection: burrows and hollow trees (use of which increased with decreasing ambient temperature) in winter, and hollow trees and dense vegetation during breeding and raising pups. The pattern of shelter use by raccoon dogs was also strongly modified by forest structure. Raccoon dogs living in the pristine old-growth stands (with large amounts of dead wood) utilized mainly natural shelters created by fallen trees (trunks, branches, and roots) and sedge tussocks (38% and 37%, respectively). Individuals inhabiting the managed part of the Forest used mainly burrows (43%) and thicket (23%). We recorded very strong monogamous relationships between pair mates, manifested by shared resting on 84% of days per year. We conclude that hiding behavior and plasticity in shelter use is a response to high mortality due to predation and to unfavorable climatic conditions. High adaptability to various environmental conditions may be one of the factors underlying successful range expansion of raccoon dogs in Europe.
