The alimentary canals of 9 species of domesticated or wild animals were examined for the presence of E. multilocularis. The tapeworm was found in 9 red foxes (Vulpes vulpes) out of 155 examined (5.8%) and in 2 raccoon dogs (Nyctereutes procyonoides) of 25 examined (8.0%). Our studies proved that in Poland the raccoon dog can also be infected with E. multilocularis.

Invasive alien species are considered to be one of the most important causes for the extinction and the reason for diminishing of the wild native species. Considering that nowadays the raccoon (Procyon lotor, Linnaeus 1758) is found in several European and Asian countries where it can amplification its ranges remarkably, but it is actually native to North and Central America. Here, we use the Maxent model to generate a preliminary map of the potential distribution of the raccoon around the world and enumerate its relative risk of invasion across all countries. In a study, MaxEnt predicted a significantly large area as the eco-climatically suitable habitat for the raccoon in the world. The predicted habitats are consistent with the wide-ranging habitat associations of the raccoon in its well-established sites. The results identified the hotspots of the raccoon invasion and indicated the possible dispersal pathways. Results also showed that both precipitation and temperature variables were strongly correlated with the raccoon distribution and the species would be absent in cold environments with average sub-zero temperatures.

The growth, size, and fat reserves of the raccoon dog Nyctereutes procyonoides (Gray, 1834) were studied in Finland in period 1986 - 1990. There was no sexual dimorphism in mean body size. Juveniles reached the mean adult body length at the age of 5 - 7 months. The weather in spring seemed to cause both annual and regional variation in the weight and fat reserves of juveniles in late autumn. Some of these differences could be seen as late as the following March, the breeding season of raccoon dogs. The adults had the least fat reserves in May and the most in October — November. The abundance of food, especially that of voles in early spring, seemed to affect the fat reserves of adult females in March.

Reproductive strategies of the raccoon dog Nyctereutes procyonaid.es (Gray, 1834) and the red fox Vulpes vulpes (Linnaeus, 1758) were studied in southern Finland in 1986-1995. Litter size and relative litter weight, body size, population status and ecology were compared. Although the body size is almost equal, diet rather similar and both raccoon dog and fox populations have been rather stable during the study period, the litter sizes and relative litter weights differ greatly. The mean litter size of the raccoon dog was 9.0 and that of the red fox 5.1. The mean relative litter weight was 18.3-24.0% for the raccoon dog and 10,4-12.5% for the red fox. Thus, raccoon dog females are able to invest relatively more in reproduction than the red fox. There are several features in the ecology and behaviour of these species which can explain the different strategies. First, vole cycles have a strong effect on red fox reproduction, but have only a week effect on the litter size of the raccoon dog. Second, the raccoon dog sleeps during harsh winters and females are in good condition in the breeding season regardless of the weather and food supply during the winter. The red fox is always active in winter when food availability may be low and moving in snow is energetically costly. Omnivory, the ability to accumulate large fat reserves and winter dormancy guarantee the good condition of raccoon dog females even in fluctuating environments by reducing the relative costs of reproduction. Third, raccoon dog pups are easy prey to other predators, and mortality during their first year is very high. If mortality rate before the reproductive age is high and independent of litter size, natural selection will favour large litters. Juvenile mortality among red foxes is lower, and it probably would increase in larger litters due to eg starvation.

The proportion of time that male and female raccoon dogs Nyctereutes procyonoides (Gray, 1834) spent at the den during pup rearing was studied in Finland using radio- tracking. Results were compared with the behaviour of some other canids. Male raccoon dogs spent even more time at the den than females, especially during the day when males remained almost 80% of the time at the den, but females only about 60%, The behaviour of males and females did not differ at night. Consequently, the behaviour of males differed at various times of day and night, but that of females did not. During the 1st month after birth pups were seldom left by themselves: during day both parents were often at the den, but at night only one of them was usually at the den. That males spend more time at the den with pups than females is common behaviour in the raccoon dog and the bat-eared fox Ofocyon megalotis. These canids feed on small food items that are difficult to carry to the den, especially if food is scarce and widely distributed. Instead, the female forages and nurses the pups, and the male guards the litter. In species with larger food items, the males usually carry food to the den. When food items are very large they cannot be carried to the den, but males and other pack members feed from the carcass and regurgitate food at the den.

Three pairs of raccoon dogsNyctereutes procyonoides (Gray, 1834) were observed by continuous radio-tracking (one 24-h session, once a week) during the first six weeks after parturition. Males spent noticeably more time (40.5% ±11.7 SD) alone with the pups than females (16.4% ±8.5 SD). Females had noticeably larger home ranges (95% kernel: 98.24 ha ±51.71 SD) than males (14.73 ha ±8.16 SD) and moved much longer daily distances (7368 m ±2015 SD) than males (4094 m ±2886 SD) in six weeks postpartum. The raccoon dogs left the breeding den in the 6th week after the birth of the pups.In situ video observation showed that the male carried prey to the den to provide the female and the litter with food. A clear division of labour took place among parents during the period in which the pups were nursed: males guarded the litter in the den or in close vicinity of it, while the females foraged to satisfy their increased energy requirements.

We compared the habitat preferences of the alien raccoon dog Nyctereutes procyonoides (Gray, 1834) and the native badger Meles meles (Linnaeus, 1758) in two areas (Ruissalo and Tuulos) in southern Finland by radio-tracking the animals during summer from 2005 to 2008. We assumed that the habitat preferences of these two medium-sized carnivores differ to some extent (ie they are able to share the resources), because they have been sympatric for more than 50 years in southern Finland and populations of both species have increased during that period. The results indicated that the habitat preferences of these species are indeed different: raccoon dogs favoured meadows, gardens and open woodlands with tall and abundant undergrowth, whereas badgers favoured both pine forests and deciduous and mixed forests with thick canopy but sparse undergrowth. However, fields were favoured by both species in one study area (Tuulos). The results show that although both species are flexible in their habitat use and share some habitat preferences, the most favoured habitats differ between the species.

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