Distance rules for minimum counts of Eurasian lynx Lynx lynx family groups under different ecological conditions

摘要: Abstract Monitoring of lynx Lynx populations in Scandinavia is largely based around unreplicated minimum counts family groups, i.e. adult females with dependent kittens. When observations cannot be separated from each other on the basis back-tracking snow it desirable to use a distance rule separate groups that are so far apart they unlikely derived same group. We have analysed radio-telemetry movement data five study areas, corresponding three ecologically different regions, Scandinavia, and included Poland for comparison. derive examples two rules; one static home-range size length which suitable accumulated during whole winter, dynamic collected within 1-7 days other. Because inter-study area variation there need rules differe...
