Wood mice, Apodemus of two Turkish islands: Gokceada and Bozcaada

Taxonomic identity of 209 wood mice (Apodemus) from Turkish islands of Gokc eada and Bozcaada was evaluated on the basis of cranial characteristics, an d using comparative mainland material from European and Asiatic Turkey. Spe cimens from Gokceada belonged to A. flavicollis, but differed from the main land sample in having longer incisive foremen and shorter palatinum. Bozcaa da was populated by A. hermonenis, which is the first record of this specie s on any island. Wood mice were the most common small mammals on both islan ds; their dominance on Gokceada was 39.6% and on Bozcaada 92.3%. We discuss zoogeographic relations of the Aegean islands on the basis of four Apodemu s species recorded there so far.
