The relationship between the straight line distances (SLD), obtained from telemetry locations, and actual distances travelled by wolves Canis lupus (ADT), measured by snowtracking, was investigated in Bialowieza Primeval Forest, E Poland, in winter 1995/96. Radiolocations determined at 15-min time intervals approximated the ADT by wolves reasonably well. If wolves were relocated at 0.5- to 2-h intervals, SLD can be multiplied by a correction factor of 1.3 to obtain ADT. Within the range of SLD from 1 to 10 km, they could also be converted into ADT using a regression equation: ADT = 0134 + 1.19(SLD), with standard errors of prediction 0.13 to ± 0.3 km. The average travelling speed of wolves was 3.78 km/h (SD 1.23, range 1.6-6.1 km). Wolves walking the forest trails, roads and frozen rivers moved significantly faster than in the forest. Also, individuals travelling with other pack members moved faster than those walking singly.

Abstract
The relationship between the straight line distances (SLD), obtained from telemetry locations, and actual distances travelled by wolves Canis lupus (ADT), measured by snowtracking, was investigated in Bialowieza Primeval Forest, E Poland, in winter 1995/96. Radiolocations determined at 15-min time intervals approximated the ADT by wolves reasonably well. If wolves were relocated at 0.5- to 2-h intervals, SLD can be multiplied by a correction factor of 1.3 to obtain ADT. Within the range of SLD from 1 to 10 km, they could also be converted into ADT using a regression equation: ADT = 0134 + 1.19(SLD), with standard errors of prediction 0.13 to ± 0.3 km. The average travelling speed of wolves was 3.78 km/h (SD 1.23, range 1.6-6.1 km). Wolves walking the forest trails, roads and frozen rivers moved significantly faster than in the forest. Also, individuals travelling with other pack members moved faster than those walking singly.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
