Abstract:Results of morphometric analysis of the mound-building mouse (Mus spicilegus) evaluated in this study originate from field trapping in the eastern part of Slovakia during the years [2003][2004][2005][2006][2007][2008]. Twenty-four cranial and dental variables and the zygomatic index (A/B) of 80 skulls (43 males, 37 females) were measured and evaluated with respect to the sex of the mice. Despite the fact that the overlap of skull measurements in adult males and females was high, sexual dimorphism was confirmed for several skull and dental traits. On average, the values for adult females of M. spicilegus were higher than males, with the exception of dental traits and the zygomatic index. Significant differences between adult males and females were found for the mean values of ten skull and dental parameters (LB, LCb, FL, LD, LMd, LaZ, LM 1 , LM1, LaM 1 and LaM1). The values for the zygomatic index (A/B) overlapped between both sexes, but the higher average values in adult males were statistically significant. The results showed that the variability of the species confirmed in this paper was probably caused only at the regional level and did not differ from the findings reported by several authors for species from neighboring countries.

Just recently, with regard to the discriminatory bias of morphometric characters, differences in the distress call were proposed as the most reliable criterion for species identifi cation (Ancillotto et al 2016).…”

Abstract The extant species of the genus Apodemus represent the most common small mammals of Central Europe. Unfortunately, their phylogenetic past is only poorly known. With the aid of detailed biometric analyses we tried to identify the first appearance of the phenotypic patterns characterizing the extant populations. We examined dental material of Apodemus from 53 community samples from the territory of the Czech Republic and Slovakia dated from the early Villanyian (MN 16/17) to the late Middle Pleistocene (Q 3) with particular respect to their correspondence with the morphometric characteristics of the extant species. While the Toringian (Q 3) interglacial samples invariably include forms identical with the extant taxa A. flavicollis, A. sylvaticus and supposedly A. uralensis (including the items corresponding to A. maastrichtiensis), the samples of Early Pleistocene age (MN 17 – Q 2) exhibited clear differences in the variation pattern which results in questioning the possibility of their co-identification with the respective extant species. In most instances they varied within the limits in resembling A. sylvaticus but exceeded its variation ranges in some non-metric characters. Regarding serious doubts on real taxonomic status of other named fossil species we propose to denote these Plio-Pleistocene sylvaticus-like phenotypes provisionally with the prior name A. atavus Heller, 1936.
