Reproduction of the red fox Vulpes vulpes in Central Italy

چکیده
The reproduction of the red fox Vulpes vulpes has been widely studied (Hayssen et al. 1993). Most features are highly variable, and reproductive output appears dependent on food availability at high latitudes (Englund 1970), whereas at lower latitudes it seems limited by social constraints (Macdonald 1980, Lindström 1989). No data on the reproduction of the red fox are available for the Mediterranean region. Barren females are present in several populations, and their proportion is variable in time and space (e.g. Englund 1970). Those females may be subordinates that help the dominant female to raise cubs (Macdonald 1979). Clumped or otherwise abundant food resources may allow the presence of subordinates, and therefore the formation of groups (Macdonald 1981, Von Schantz 1984a), and Reproduction of the red fox Vulpes vulpes in Central Italy
