Ranging behaviour and activity of five [2 females, 3 males) red foxes Vulpes uulpes (Linnaeus, 1758) in the Mediterranean coastal area of Maremma Natural Park (central Italy; an area of great habitat diversity) are described. One female ranged over a very small area and had diurnal activity rhythms, For other foxes, home range size (100% minimum convex polygon) varied between 86 and 485 ha (larger than fox ranges in urban areas and smaller than in northern or homogeneous areas), and core areas (50% harmonic mean) between 4.0 and 13.7 ha. Habitat diversity within home ranges was significantly higher than that of the overall area. Within their home ranges, foxes selected scrubwood for resting. When active, they showed individual differences in habitat selection. Peak activity was between 20.00 h and 22.00 h, but foxes were active also during the day.

Food habits and trophic niche overlap of the red fox and the stone marten in a Mediterranean rural area

The food habits of the red fox Vulpes uulpes (Linnaeus, 1758) and the stone marten Martes foina (Erxleben, 1777) were studied in a rural hilly area in Siena county, central Italy, using faecal analysis. Both frequency of occurrence and volume of the different foods were quantified. Rodents, especially Apodemus sp., were an important prey for both species. Predation on poultry and game birds was nearly absent, whereas fruits and insects were seasonally taken by both species. Rosaceae fruits were the most eaten plant item. Within this category the fox fed mainly on Malus sp. and Pyrus sp., while the marten showed a preference for Rubus sp. and Sorbus domestica. Only fruits of Prunus spinosa were eaten in comparable quantities. Beetles were well represented in the diet of both carnivores, although they tended to concentrate on different species. Grasshoppers were preyed in small quantity. The overall diet overlap of foxes and stone martens was extensive: a surprising result, if the different body size, locomotor adaptations and living habits of these carnivores are considered.

Do male roe deer clump together during the rut?

Movement s an d habitat use of 7 male and 7 female roe deerCapreolus capreolus (Linnaeus, 1758) were studied by radioteleme try from March 1999 to February 2001. Annual and bimonthly home ranges of males were small (ca 10 ha, 95% kernel), with large overlap among individuals throughout the year. Exclusive core areas (ca 0.4 ha, 25% kernel) were concentrated in the forest, a limited and sought-after resource in the study area. The difference in overlap between male exclusive core areas and female home ranges in the pre-rut and rut periods suggested that females made excursions to search for territorial males during the rut Our results support the mating strategy hypothesis of territorial behaviour Different space use patterns occurred between the sexes, with females apparently playing an active role in mate choice by visiting males at clumps of core areas in the forest.

Grouping in roe deer: an effect of habitat openness or cover distribution?

nr 2

Counts of roe deer Capreolus capreolus (Linnaeus, 1758) were conducted in the open fields of two reserves in Siena county (central Italy). Area A and area B were characterized by different indices of wood dispersion (0.8 and 1.6 respectively). Solitary roe deer were seen significantly more often in area B (open fields: 80%) than in area A (open fields: 48%). Males were significantly more solitary than females in both areas. Group size varied throughout the year, showing similar tendencies in both sexes and areas. The differences in deer concentration between areas appeared to depend on the distribution pattern of woodland more than proportion of open habitat.
