Predation on dormice in Italy
Abstract The authors analyse available data on the impact of predators on Dormouse populations in Italy. Dormice are found in the diet of 2 snakes ( Vipera berus and V. aspis ), 2 diurnal birds of prey ( Buteo bute o and Aquila chrysaetos ), 6 owls ( Tyto alba , Strix aluco , Asio otus , Athene noct...

| Summary: | Abstract The authors analyse available data on the impact of predators on Dormouse populations in Italy. Dormice are found in the diet of 2 snakes ( Vipera berus and V. aspis ), 2 diurnal birds of prey ( Buteo bute o and Aquila chrysaetos ), 6 owls ( Tyto alba , Strix aluco , Asio otus , Athene noctua , Bubo bubo and Glaucidium passerinum ) and 9 mammals ( Rattus rattus , Ursus arctos , Canis lupus , Vulpes vulpes , Martes martes , M. foina , Meles meles , Felis silvestris and Sus scrofa ) in a variable percentage of the prey taken. Only Dryomys nitedula was never encountered as a prey item. The most common prey is Muscardinus avellanarius . There are significative regional differences in predation between bioclimatic areas of the Italian peninsula. The contribution of studies on predation to knowledge of Myoxid distribution is discussed. Riassunto Predazione di Mioxidi in Italia - Sono analizzati i dati pubblicati sull'impatto dei predatori sulle popolazioni di Myoxidae in Italia. Myoxidae sono stati riscontrati nelle diete di 2 serpenti ( Vipera berus e V. aspis ), 2 rapaci diurni ( Buteo buteo e Aquila chrysaetos ), 6 notturni ( Tyto alba , Strix aluco , Asio otus , Athene noctua , Bubo bubo e Glaucidium passerinum ) e 9 mammiferi ( Rattus rattus , Ursus arctos , Canis lupus , Vulpes vulpes , Martes martes , M foina , Meles meles , Felis silvestris e Sus scrofa ) in percentuale variabile nella comunità di prede. Solo Dryomys nitedula non è mai stato incontrato come preda. La specie piu comunemente predata risulta Muscardinus avellanarius . Sono discusse le significative differenze di predazione per aree bioclimaticamente diverse e l'apporto dello studio delle predazioni alle conoscenze sulla distribuzione dei Myoxidae in Italia. |
