“…A Euromax binocular microscope is used to examine all specimens at 10x – 50x magnification. Our taxonomic identification focused on isolated dental elements (maxillae, mandibles, incisors and molars) and select post-cranial elements via direct comparison with osteological collections at the University of Tübingen and published morphological and metric data including Adadjanian and von Koenigswald [35], van Kolfschoten [36] and Nadachowski [37] for Arvicolidae, Corbet [38] for Gliridae, Ziegler [39] for Talpidae, Popova [40,41] and Cubuk [42] for Sciuridae, Reumer [43] and Heinrich [44] for Soricidae, and Storch [12] and Sevilla [45] for Chiroptera. We identified arvicolid taxa by a combination of lower m1 occlusal morphology and occlusal measurements which follow van Kolfschoten [36].…”

The loss of Neanderthal groups across Western and Central Europe during Oxygen Isotope Stage (OIS) 3 has held the attention of archaeologists for decades. The role that climatic change, genetic interbreeding, and interspecies competition played in the extinction of Neanderthal groups is still debated. Hohle Fels is one of several important Middle and Upper Paleolithic sites from the Ach Valley in southwestern Germany which documents the presence of Neanderthals and modern humans in the region. Chronological and stratigraphic records indicate that these two groups occupied the site with little to no overlap or interaction. This provides the opportunity to examine the behavioural variability of Swabian Neanderthal populations without the complication of cross-cultural influence. In this study we contribute a terrestrial paleoenvironmental record derived from the small mammal material from Hohle Fels Cave to the ever-growing archaeological record of this period. By reconstructing the climate and landscape of the Ach Valley during this time we can identify the effect that the OIS 3 environment had on the presence of Neanderthals in the region. Based on indicator taxa and the habitat weighing method, the small mammal record, which includes rodents, insectivores, and bats, from Hohle Fels shows that the earliest Neanderthal occupation took place on a landscape characterized by substantial woodland and forest, rivers and ponds, as well as moist meadows and grasslands. A gradual increase in cold tundra and arctic environments is clear towards the end of the Middle Paleolithic, extending to the end of the early Aurignacian which may correlate with the onset of the Heinrich 4 event (~42,000 kya). Our taphonomic analysis indicates the material was accumulated primarily by opportunistic predators such as the great grey owl, snowy owl, and European eagle owl, and therefore reflects the diversity of landscapes present around the site in the past. Importantly, at the time Neanderthals abandoned the Ach Valley we find no indication for dramatic climatic deterioration. Rather, we find evidence of a gradual cooling of the Swabian landscape which may have pushed Neanderthal groups out of the Ach Valley prior to the arrival of modern human Aurignacian groups.

Range dynamics in sibling species: facts and reconstructions for the mammal fauna of Eastern Europe. -I. Zagorodniuk. -The specifics of distribution and status of local mammal species of sibling complexes demonstrating signs of significant either current or recent range dynamics are considered. These species complexes comprise pairs of sibling and morphologically close species, which until recently have not been unambiguously distinguished, thus it was impossible to analyse their range dynamics. However, range dynamics of this group of species is of great interest since it determines the emergence of high species diversity and realisation of mechanisms of compact organisation of communities that include close species. The amassed by today knowledge on distribution of species and the identification criteria developed for some of those species based on collection specimens allow to analyse changes in their distribution ranges. Such data in most cases allow to perform reconstructions and to develop respective hypotheses on dispersal routes of species in the region. In total, 9 species complexes were considered. Ranges of species that by direct or indirect evidence demonstrate changes in the area of their distribution and in the same time change the system of interspecific spatial relationships within each group are described. These spatial relationships can vary from allopatry to marginal or significant sympatry. Such complexes of "small" species were described in the composition of former "large" polytypic species with signs of invasions or expansions of their components among bats (Plecotus auritus + austriacus, Pipistrellus pipistrellus + pygmaeus, Eptesicus serotinus + lobatus) and rodents (Spermophilus suslicus + odessanus, Microtus arvalis + obscurus, Mus musculus + spicilegus). Similar but less expressed signs can be also traced in some other groups (Spalax zemni + arenarius, Sylvaemus sylvaticus + whiterbyi, Capreolus capreolus + pygargus). Distribution maps for all these species complexes are presented with reconstructions of possible directions of their dispersal through the territory of the region (Ukraine and adjacent countries). Zones of prochoresis, where these species most likely were absent in the recent past, are determined and analysed. The time and pace of expansion of "small" species in the region are estimated. The significance of morphological criteria of species and the possibilities of revision of old collection specimens to analyse temporal changes of biota are shown as well as the importance of cartographic data for such analysis. By using data from revisions, it is possible to estimate geographical tendencies and velocity of expansion for many species, including those that represent groups of morphologically close or sibling species. K e y w o r d s : sibling species, mammals, range dynamics, biological invasions, biogeography, Ukraine.

Close non-murid rodent species in the fauna of Ukraine: differences, biogeography, and ecomorphology. -I. Zagorodniuk. -Results of taxonomic revisions, analysis of identification criteria, spatial and ecomorphological differentiation of close pairs of species are summed up. Increased taxonomic heterogeneity is characteristic for 4 superspecies: Spermophilus suslicus s. l. (2 species), Sicista subtilis s. l. (2 species), Sicista betulina s. l. (2 species), and Spalax zemni s. l.(2 species). Unlike other groups of small mammals (in particular, bats and rodents of the superfamily Muridae s. lato, seu Muroidei), all these superspecies complexes are represented by allospecies. Accordingly, the differences between them by eco-morphological characters are minimal or absent. It was revealed that sympatry in each group is possible only with species from adjacent taxa of the same ecomorphological groups, in particular, susliks with marmots, forest birch-mice with steppe birchmice, and mole rats with mole voles. In all these allospecies complexes, all species are related to the foreststeppe or steppe faunal complexes (except for the northern forest birch-mice from the superspecies Sicista betulina s. l.), as well as their spatial differentiation is based on the principal inter-river spaces, and the boundaries of their ranges are large watercourses. One of the key factors of spatial segregation is the delimitation by large rivers, first of all the Dnipro, Dnister, Tyligul, Molochna, and Donets. Cases of sympathy, even marginal, have not been revealed, but the analysis of ancient literature and collections show signs of recent expansion of species. In particular, signs of the expansion of Spermophilus odessanus to the west were detected; probably the same applies to Sicista loriger and Spalax zemni. The key biogeographic coordinate of the whole complex of "small" species of non-Muroidei rodents is the Lower Dnipro, in particular the triangle between the Lower Dnipro, the Black Sea, and the Molochna river. Guilds in all these groups are as simple as possible (practically mono-species), and in addition, three of four of these groups are presented by hibernating animals (fourth group is underground rodents). Unlike other groups of mammalian siblings, all analyzed species do not show any tendency to synanthropy and are in need of special conservation measures. K e y w o r d s : rodents, non-Muroidei, taxonomy, distribution, differences, ecomorphology.
