Yearling natal dispersal frequencies and distances in roe deer Capreolus capreolus were compared ... more Yearling natal dispersal frequencies and distances in roe deer Capreolus capreolus were compared between two regions in Scandinavia, Västerbotten, on the northern edge of the expanding population, and Mälardalen, in the central continuous part. Data were collected using telemetry during 1987–1994. In Västerbotten 91% (n = 11) of the males and 100% (n = 9) of the females left their natal areas, and in Mälardalen 43% (n = 42) of the males and 48% (n = 50) of the females dispersed. No intra‐regional difference in distances dispersed was found between sexes. Average dispersal distance in Västerbotten was ca 120 km (n = 17), with only one disperser settling less than 39 km from its natal area. In Mälardalen, the average dispersal distance was around 4 km (n = 42), and only two animals moved further away than 15 km. One hypothesis accounting both for the almost complete dispersal of deer in Västerbotten, and for the existence of a few long‐distance dispersers in Mälardalen, is that two ge...

In this study, we examined various aspects of natal dispersal by Eurasian lynx in Scandinavia by comparing dispersal patterns of 120 radio‐marked lynx in two study areas in Sweden (Sarek and Bergslagen) and two study areas in Norway (Hedmark and Akershus). We found that male lynx dispersed farther than female lynx with mean dispersal distances of 148 and 47 km for male and female lynx that were followed to the age of 18 months or older (range = 32–428 and 3–215 km for each sex, respectively). In fact, female lynx often established home ranges that overlapped or partly overlapped that of their mothers. Similarly, the dispersal rate was greater among male lynx than among female lynx, with 100% of the males dispersing compared with 65% of the fem...
