Abstract
Miller (1967) has indicated that the coexistence of Apodemus sylvaticus and A. flavicollis may be possible if A. flavicollis, a species with a more restricted niche, is competitively superior in interspecific encounters. Intra- and interspecific behaviour of male and female A. sylvaticus and A. flavicollis was examined in dyadic encounters in a small arena. Interactions between conspecifics indicate that intraspecific behaviour in A. sylvaticus and A. flavicollis is similar but, in interspecific interactions there were more submissive and agonistic acts, and less introductory and amicable behaviour. A. flavicollis was dominant to A. sylvaticus in 63 out of 70 encounters and A. sylvaticus dominant in only one. This superiority may contribute to the persistence of small, localized populations of A. flavicollis despite the presence of A. sylvaticus.
