Prey density, environmental productivity and home-range size in the Eurasian lynx (Lynx lynx)

摘要: Variation in size of home range is among the most important parameters required for effective conservation and management a species. However, fact that ranges can vary widely within species makes data transfer between study areas difficult. Home Eurasian lynx Lynx by factor 10 different Europe. This aims to try explain this variation terms readily available indices prey density environmental productivity. On an individual scale we related sizes 52 ranges, derived from 23 (9:14 male:female) resident obtained south-eastern Norway, with index roe deer Capreolus capreolus. was harvested municipalities covered ranges. We found significant negative relationship harvest homerange both sexes. European level 111 (48:63 male: female) sites estimates remote sensing productivity seasonality. A multiple linear regression model indicated site had clear home-range size. At scales, sex emerged as explanatory variable males having larger than females. In addition, male home-ranges increased faster decreasing These analyses support held predictions due density.
