摘要: Counts of reproductive units, i.e. family groups, constitute the main monitoring index for lynx Lynx populations in Scandinavia. However, some purposes it is necessary to extrapolate from number groups obtain an estimate total population size. Using data on survival and reproduction radio-marked three Scandinavian study areas, we simulated structure February. The average proportions out all independent individuals, adults yearlings, these simulations were 21% ± 2.1 (SD), 22% 3.6 27% ±3.1 sets northern Sweden (Sarek), southeastern Norway (Hedmark) south-central (Bergslagen), respectively, overall mean areas was 23% 3.8. This translated into extrapolation factors 6.14 0.44,6.24 0.73 5.48 0.40 leading 5.95 0.64. We conclude, that possible size with a statistical measure uncertainty.
