“…Since data on raccoon dog's home range size collected in a previous study in the Federal State of Mecklenburg-Western Pomerania (Drygala et al 2008b), took place also in a landscape dominated by farmland use, we expected similar results for home range sizes.…”

“…As has been shown in previous studies, the monogamous relationship between pair mates results in similar home range sizes for male and female raccoon dogs (Kauhala et al 1993;Saeki 2001;Drygala et al 2008b;Kowalczyk and Zalewski 2011). We therefore included the data for M4 in our calculations for average home range sizes of adult raccoon dogs (Tables 1 and 2).…”

“…Finally, based on the mean annual home range size, average local population densities during summer and during winter were calculated Our study area with its agricultural landscape largely represents the Eastern German lowland. We supposed population densities and home range sizes of raccoon dogs living here to be comparable with those observed in Mecklenburg-Western Pomerania with similar farmland structure (Drygala et al 2008b). Based on differences in seasonal activity, we expected especially small home range sizes during winter.…”

The raccoon dog Nyctereutes procyonoides, a medium-sized canid, is a representative of the East Asian fauna and has been introduced to Europe during the years 1928-1953. Today, this alien carnivore is a widespread species in Eastern Europe, Finland and Germany. In our study, we determined home range sizes of raccoon dogs in an agricultural landscape in Northeast Germany between 2001 and 2004 by very high frequency radio tracking. Those data are useful for estimation of predator densities in respect to conservation of biodiversity and also to develop models for disease and parasite transmission. Yearly average home range sizes were calculated as 95% fixed kernel: 1.83 km 2 ±1.54 and as 50% fixed kernel (=core areas): 0.50 km 2 ±0.49. We documented seasonal differences in home range sizes as well as overlapping of home ranges from 0.65% up to 67%. Some individuals' home ranges recorded during the same season showed a clear shifting between different years. Abandoned badger dens, located in the core areas of raccoon dogs home ranges, were important during the whole year and particularly used in the winter period. Therefore, distribution of those dens had some influence on the spatial distribution of raccoon dogs in the study area. Based on mean annual home range size, we estimated the mean local population density during winter as 1.1 individuals per square kilometre and during summer as 4.90 individuals per square kilometre.

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.

Interactions between density, home range behaviors, and contact rates in the Channel Island fox (Urocyon littoralis)

Many of the mechanisms underlying density-dependent regulation of populations, including contest competition and disease spread, depend on contact among neighboring animals. Understanding how variation in population density influences the frequency of contact among neighboring animals is therefore an important aspect to understanding the mechanisms underlying, and ecological consequences of, density-dependent regulation. However, contact rates are difficult to measure in the field and may be influenced by density through multiple pathways. This study explored how local density affects contact rates among Channel Island foxes (Urocyon littoralis) through two pathways: changes in home range size and changes in home range overlap. We tracked 40 radio-collared foxes at four sites on San Clemente Island, California. Fox densities at the four sites ranged from 2.8 ± 1.28 to 42.8 ± 9.43 foxes/km2. Higher fox densities were correlated with smaller home ranges (R2 = 0.526, F1,38 = 42.19, P < 0.001). Thirty foxes wore collars that also contained proximity loggers, which recorded the time and duration of occasions when collared foxes were within 5 m of one another. Contact rates between neighboring fox dyads were positively correlated with home range overlap (R2 = 0.341, P = 0.008), but not fox density (R2 = 0.012, P = 0.976). Individuals at high densities had more collared neighbors with overlapping home ranges (R2 = 0.123, P = 0.026) but not an increase in the amount of contact between individual neighbors. This study was the first time contact rates were directly measured and compared to density and home range overlap. Results suggest that foxes exhibit a threshold in their degree of tolerance for neighbors, overlap is a reliable index of the amount of direct contact between island foxes, and disease transmission rates will likely scale with fox density.
