- Abstract
Results from four combined experiments using a capture-mark-recapture technique followed by Standard-Minimum removal were analysed. Trappability of non-reproductive subadults and post-reproductive adults was Lower than that of reproductive adults, and the removal of subadults was slower than the removal of adults, especially of reproductive adult males. Among subadult and reproductive C. glareolus (Schr.), 33% and 8% respectively were unmarked. In A. flavicollis (McLch.) 70% of the subadults and 28% of the reproductive adults were unmarked. A considerable edge-effect in Standard-Minimum removal was demonstrated for all groups except for subadult A. flavicollis. However, this effect could in all cases be ascribed to lower trappability of individuals with homesranges partly overlapping the study area. It is concluded that reproductive C. glareolus and A. flavicollis and subadult C. glareolus are generally resident; as to subadult A. flavicollis no final conclusion can be made.
