However, although cage-traps could not supply useful information range boundaries or swift acknowledgment boundary changes, centres activity calculated from trap data comparable with those data. Tracking rates individuals variable; it would be risky assume that they accurately reflected intensity use any short periods when may have been competing baits. had stable ranges; 3 females predominantly exclusive each other. progressive removal study eff...
