Diet variations across remote populations of a widely distributed snake species, the Asp viper (Vipera aspis aspis; Linnaeus 1758)
Résumé
Diet variations across remote populations of a widely distributed snake species, the Asp viper (Vipera aspis aspis)-1st Peer Review. Diet variations across remote populations of a widely distributed snake species, the Asp viper (Vipera aspis aspis; Linnaeus 1758) Vipera aspis is a common species extending from west France to Switzerland, south Italy and north Spain. This snake inhabits a great variability of habitats, including plains nearby the Atlantic Ocean, Mediterranean habitats or mountainous alpine meadows. Diet may vary across habitats (e.g., plains, scrublands, mountains). Conversely, Vipera aspis may select a narrow spectrum of prey. We addressed this issue in the subspecies Vipera aspis aspis. Combining fieldwork and Museum specimens, we examined 1,680 vipers and collected 605 prey' observations. We compared five areas encompassing contrasted habitats (map below).
