| Zur Raumorganisation der in den Schweizer Alpen wiederangesiedelten Population des Luchses Lynx lynx | |
| 1986 Zeitschrift fr Sugetierkunde (51): 289-311 | |
Tracked 10 lynxes (_Lynx lynx_) which were captured and fitted with radio collars. The study was made between 1983 and 1985, 10+ years after the reintroduction. In the northern Alps, where the lynx population was first established, the home range sizes of four adults varied from 450 km2 to 275 km2 for males, and 135 km2 to 96 km2 for females. In the Valais (central Alps), near the present border of the expanding population, an adult female was tracked on 46 km2. Occasionally, lynxes roamed outside their home ranges (especially males during the mating season). Including all locations one male ranged over 1860 km2. The home range of one female was overlapped almost completely by that of a male. A young female dispersed and lived on only 5 km2 for more than three months in a valley not used by lynxes before. Probably, lynxes capture easy prey in new areas and can live on small home ranges. While the ungulates gradually adapt to the presence of lynxes, the space requirements increase. At present, the lynx occurs in the northern Alps mainly in large (over 500 km2) forest areas where we estimate the populations density at about 1 adult animal per 85 km2. |
