摘要: We reviewed 20 studies on wolf diet in Italy, to relate the changes composition increase of wild ungulate population Italy. Researches covered period from 1976 2004 and whole range wolves southern Apennines western Alps. used frequency occurrence seven food categories species occurring diet. Estimates populations were obtained literature we extrapolated their trend considered. Differences among geographic areas (south-central Apennines, northern Alps) tested by nonparametric multivariate analysis variance, while trends livestock use breadth analysed regression curve-fit analyses. same method support relationships between availability ungulates. Wolves preyed herbivores more Alps than Apenni...
