Mus musculus: Experimental Induction of Territory Formation

Abstract

In groups of house mice (Mus musculus) an experimentally imposed sequence of experience led to the establishment of male territories in suitably designed observation pens. This sequence consisted of familiarization with the area followed by combat with and social dominance over another male who was then removed, and a final step in which defeat on the home ground of a similarly experienced male was coupled with victory over the latter on familiar ground.
