The relationships and ecology of Apodemus sylvaticus from the Small Isles of the Inner Hebrides, Scotland



Island “races” of the field mouse (Apodemus sylvaticus) have often been used to support particular theories of colonization or microevolution. Comparisons between Apodemus from a group of four islands in the Inner Hebrides (Rhum, Muck, Eigg and Canna) give support to the idea that the amimals were introduced onto these islands by man—mice first becoming established on Eigg and thence being transported to the other islands.
