Spatial organization of a lynx population
I examined the home-range relationships and spatial organization of an untrapped lynx (Lynx canadensis) population in the southern Northwest Territories, Canada. I determined annual home ranges and static and dynamic interactions among 30 radio-collared adult lynx from April 1989 to April 1993. Dens...

Most intrasexual dynamic interactions indicated neither attraction nor avoidance, suggesting that home-range boundaries were maintained by passive means.
