Karyotyping and several molecular methods have allowed successful
identification of two morphologically similar wide-ranging Western
Palearctic species, the yellow-necked field mouse Apodemus flavicollis
(Melchior, 1934) and the long-tailed wood mouse A. sylvaticus (Linnaeus,
1758), but reliable species diagnosis on the basis of morphometric
characters is particularly problematic. Although they are easily
morphologically distinguishable in Central and Northern Europe, this is
not the case in southern parts of their distribution areas. Despite
that, we have successfully discriminated A. flavicollis and A.
sylvaticus from Serbia (Southern Europe) using geometric and traditional
morphometric methods on a data set for ventral crania of specimens
previously genotyped by the Inter Simple Sequence Repeat-PCR (ISSR-PCR).
Discrimination power of applied approaches was more or less similar. The
majority of our results were consistent with those obtained for
specimens collected across the Czech Republic (Central Europe).
Morphological differences observed herein, as well as those already
reported between A. flavicollis and A. sylvaticus from the central and
northern parts of their distribution areas, could be the outcome of
their biology, i.e. ecological discrepancies, different assumed
evolutionary scenarios considering biogeography, phylogeny, history and
ontogeny. (C) 2014 Elsevier GmbH. All rights reserved.
