“…The importance of maize in the diet of the badger has also been pointed out in other studies, especially in other areas of Switzerland (Stocker & Lüps, 1984;Lüps et al, 1987Lüps et al, , 1991Roper & Lüps, 1995) or in areas lying in the same latitudes (Mouches, 1981;Canova & Rosa, 1994).…”

In our study three badger Meles meles populations separated by only a few km but subjected to different environmental conditions were compared. Differences are especially marked for climatic factors, the three areas being located at different altitudes, and for intensivity of soil use by people. The diet of the three populations was significantly different, with one or two dominant items in each area: mammals and cereals in the mountain, maize in the mid-mountain and in the lowland areas. In the most intensively cultivated area, maize was the most consumed item in autumn and spring, several months after harvesting. Earthworms had only a secondary importance in the diet in the mountainous area, but were negligible in the mid-mountain and lowland areas. Soil management seemed to play a preponderant role, mostly owing to soil quality and topography. Climate seemed to have a secondary effect only.

“…All animals killed before 2100 h had 'empty' stomachs (ie total contents were less than 20 ml). Conversely, stomachs containing more than 200 ml were found only in animals killed after 0200 h. Thus it seems reasonable to conclude that total volume of stomach contents is approximately related to time of death, though it is also known to vary with season (Stocker and Lüps 1984). Table 1 summarises the overall contents of the 85 stomachs in terms of (a) total volume of each prey category ; (b) frequency of occurrence of each prey category ; and (c) mean volume of each prey category per stomach, taking into account only those stomachs in which a given prey category was present.…”

“…Stomach contents were removed from 138 badgers collected by the Berne Natural History Museum from 1973 to 1982 (for further details see Stocker and Lüps 1984 ;Lüps 1984). The animals were collected from an area of 650 km 2 in the Swiss midlands, mostly consisting of a hilly region (500 to 950 m) to the south-east of Berne.…”

We report the contents of 138 badger stomachs collected in central Switzerland between 1973 and 1982. Fifty-three stomachs were classified as * empty' (ie containing less than 20 ml of material). The contents of the remaining 85 stomachs were analysed in terms of the volume of material in each of eight categories : voles, slugs, earthworms, wasps, cherries, plums, maize, and Other*. The main conclusions are :1) There were no sex differences either in the total volume of stomach contents, in the proportion of stomachs classified as * empty', or in the relative importance of different prey types.2) Earthworms (Lumbricus sp.) were the most important prey type overall, accounting for 25 % by volume of total stomach contents and occurring in 54 % of stomachs. Wasps, cherries, plums and maize each contributed between 10 and 20 % of total contents ; slugs and voles were less important prey.3) Earthworms were eaten frequently but were not usually present in large volumes in any one stomach. Wasps, cherries, plums and maize, by contrast, were eaten infrequently but in large volumes ; and sometimes they were the only prey eaten in a single night. 4) A variety of foods which were present in the environment and which are known to be eaten by badgers elsewhere (eg. acorns, apples, wheat) did not appear in the stomach contents.5) It is misleading to characterise badgers either as food specialists or as generalists. Consumption of any one food in any one night depends on a variety of factors, including availability of that food, availability of alternatives, intrinsic taste preferences and previous experience.Zusammenfassung. -Von 135 in den Jahren 1973-1982 gesammelten Dachsen wurde der Mageninhalt untersucht. Bei 53 fanden sich 20 ml oder weniger absiebbaren Inhalts ; sie wurden als « leer » nicht weiter analysiert.

“…Predominant vegetal species in the wooded pastures are spruce (Picea abies) and plane (Acer pseudo-platanus) trees, as well as bushes such as the dog rose, Rosa canina. Cereals are not commonly grown, and maize (Zea mais), which was frequently found in the diet of badgers living in the Swiss Midlands (Stocker and Lüps 1984), does not occur in the area (Fischer et al 2005). Small patches of forest dominated by spruce (Abieti-Fagetum) also occur over 20% of the area.…”

This study reports for the first time data on the spatio-temporal ecology of badgers living in a cold and wet mountain region (Swiss Jura Mountains). The home range, movements, activity patterns and habitat use of three badgers (two males, one female) were examined using radiotelemetry. Average home range size was 320 ha (MCP 100%), but the ranging behaviour of badgers varied at a seasonal scale. As in other regions, badgers were strictly nocturnal or crepuscular and showed a marked reduction of activity in the winter period. From spring to autumn, animals were active for an average (±SD) of 8.1±2.4 h and travelled up to 9,460 m each night (mean±SD, 5,160± 2,600 m). The nightly distance travelled by badgers was positively correlated with their travel speed, the duration of the activity period and the used area, but not with night length. Year-round, the radio-collared animals avoided pastures and the vicinity of houses during their night trips. In winter and spring, individual badgers used forests and wooded pastures more than expected according to their availability, whereas cereal fields were actively selected in summer and autumn. Den-watching, night-lighting and radio-tracking data suggest that badgers live in pairs in this wet and cold region. Population density estimates range from 0.4 to 1.5 individuals/100 ha. We discuss the importance of trophic resources and climate as factors influencing badger behavioural ecology.
