L'activité hivernale d'une petite population de Vipera aspis (4 mâles adultes et 3 femelles adultes) a été étudiée au cours de trois hivers à l'aide du radio-pistage. Presque tous les individus sont restés actifs, se cachant simplement sous les feuilles, se déplaçant d'un refuge à l'autre en effectuant des distances d'environ 150 m. Approximativement 50 % des serpents étaient actifs au soleil (29 % du total des journées d'observation). Les domaines vitaux et les zones de principale fréquentation sont statistiquement identiques entre les sexes, bien que légèrement supérieurs chez les mâles. Les tailles observées pour les domaines vitaux sont remarquablement grandes pour des périodes hivernales durant lesquelles l'activité est censée être trè...
