摘要: We conducted a radio-telemetry study of translocated brown hares Lepus europaeus during March 1992 - November 1994 in mid-elevation mountain site central Italy. Of 44 released the area, 38 died our field studies. Most (68.2%) within 10 days after release, 7.89% 11–20 days, 2.63% 21–30 and 21.05% later than 30 release. found no difference mortality rates between sexes. were preyed upon by red foxes Vulpes vulpes or beech marten Martes foina, but few coccidiosis various natural diseases. Some disappeared monitoring period. The average survival time was 52.7 for males (N = 20), 66.8 females 21). significant effect sex, season weight (g) on individual survival. Nearly all dispersed randomly from release radius 1,200 m. dispersal rates, nor did we find any intersexual maximum distances moved individuals. not observe this trend among females. Season, influence dispersal, whereas sex had effect, as tended to disperse farther
