RANGE UTILIZATION AND ACTIVITY OF RADIO-COLLARED YELLOW-NECKED MICE APODEMUS-FLAVICOLLIS MELCHIOR, 1834

Investigated range utilisation and activity of yellow-necked mice Apodemus flavicollis in an agricultural area and in a montane forest, 7 individuals were radio-tracked over a period of 5 months, and 1737 locations recorded. Mean home range for adult A. flavicollis measured 15,500 m(2) for males and 7,400 m(2) for females during and 3,800 m(2) respectively 3,600 m(2) outside the mating season, and they overlapped considerably. Females monopolized core areas against other females. During the breeding season males moved faster and covered longer distances than females. Outside the hiding places, A. flavicollis' activity is crepuscular and nocturnal. In summer, only females visited their hides, occasionally, whereas in fall a male spent extended periods resting in his hides. Up to 7 different hides were used by the same individual.
