Home range size and activity pattern were evaluated by radiotracking for seven red fox Vulpes vulpes (Linnaeus, 1758) breeding females, in the Doñana Biological Reserve, SW Spain. Mean home range size was 218 ha (SD = 76, n = 7). A home range for one of the seven females was 1129 ha for one nearly complete year and only 253 ha for the same female during the breeding season. We suggest that this size reduction could be a result of energetical and behavioral shifts due to the breeding condition. Activity was slightly increased during nights with long resting periods during light hours. Total mean travelling distances was 6686 m in 24-hour cycles. Daytime and nighttime mean distance covered were 2101 and 4585 m, respectively.

Seasonal feeding habits of the Patagonian hog-nosed skunk Conepatus humboldtii in Southern Patagonia

Diet of Patagonian hog-nosed skunk Conepatus humboldtii Gray, 1837 was studied in southeastern Argentinean Patagonia. Faeces from skunks were collected and analysed on a yearly basis. A wide variety of prey ranging from invertebrates (81.6% of occurrences), mammals, reptiles and plant material occurred in the faeces. Though Patagonian hog-nosed skunk was reported as primarily insectivorous regarding its feeding anatomy and behaviour, vertebrate prey predominated over invertebrates when results were expressed as consumed biomass. The consumption of invertebrate prey increased during summer, probably due to an increase in its abundance. The increase in the consumption of rodents and carrion by skunks during autumn-winter could be due to a shift from open grassy areas to other habitats to find alternative prey.
