dc.description.abstract | We explored modularity and morphological integration of the
ventral cranium during postnatal ontogeny in Martino’s vole
(Dinaromys bogdanovi). Two closely related phylogenetic
groups, originating from the Central and Southeastern part of
the species range in the western Balkans, were considered. As
expected, both phylogroups had similar patterns of ontogenetic
changes in cranial size and shape variation, modularity and in-tegration. At the level of within individual variation, the hy-pothesis that the viscerocranial and neurocranial regions are
separate modules was rejected, indicating that the hypothesized
modules are not developmental, but rather functional. At the
level of among individual variation, the viscerocranium and the
neurocranium could not be recognized as separate modules at
the juvenile stage. The strength of association between the hy-pothesized modules becomes lower with age which finally re-sults in a clear 2-module organization of the ventral cranium at
the adult stage. On the other hand, patterns of morphological
integration for the cranium as a whole, the viscerocranium and
the neurocranium stay consistent across ontogenetic stages. The
developmental mechanism producing integration of the crani-um as a whole, as well as integration of the neurocranium, var-ies throughout postnatal ontogeny. In contrast, we detected the
ontogenetic stability of the mechanism responsible for covaria-tion of viscerocranial traits which could provide ongoing flexi-bility of the viscerocranial covariance structure for high func-tional demands during lifetime. Findings from our study most
likely support the idea of the ‘palimpsest-like’ model of covari-ance structure. Moreover, similarity or dissimilarity in the pat-terns of within and among individual variation in different sets
of analyzed traits and comparisons across ontogenetic stages
demonstrate how studies on small mammals other than mice
can give new insights into postnatal cranial development. | sr |
