The rediscovery of old collections and revision of the fossil material from more than 30 Sudeten caves and rock shelters allow reconstructing the faunal changes during the Late Pleistocene and the Holocene. We found that the composition of mammalian assemblages of Sudety Mts during MIS 3 differed significantly from the Holocene and modern one, and reflected the colder climate. Mammals belonging to the Mammuthus-Coelodonta faunal complex inhabited open flattened lowlands (Bohemia, Moravia and Silesia) surrounding Sudeten area. Several large carnivores (Canis lupus spelaeus, Ursus arctos priscus, Ursus ingressus, Gulo gulo, Mustela eversmanii, Panthera spelaea spelaea, Crocuta crocuta spelaea) as well as herbivores (Mammuthus primigenius, Coleodonta antiquitatis, Megaloceros giganteus, Rangifer tarandus, large form of Equus ferus, Bison priscus, and Ovibos moschatus) made up the core of this assemblage. Our studies showed that most of these faunal elements were also present in Sudety Mts, despite the previous opinion that these mountains formed an effective natural barrier during the Late Pleistocene. Besides, it seems that during cold phases they could be refugees for forest animals, which were also present in the Mammuthus-Coelodonta faunal complex, but lower quantities. They avoided flat treeless Silesian lowlands and concentrated in mountainous and hilly regions. In this context, during the Late Pleistocene Sudety Mts were a “forested island” confined to elevated areas or river valleys. Range extensions, contractions, and continuations on different scales resulted in mammalian paleoassemblages which differed in particular from the modern ones. The analysis of the mammal faunas from Sudeten sites revealed that there were three heterochronous mammalian faunal complexes replaced each other throughout the Late Pleistocene and the Holocene. Differences between these assemblages resulted from changes in morphology, areas and extinction of several species. The existence of different faunal elements was distinguished by the chronological and geographical change in the structure of mammalian assemblages. At the end of MIS 3 most of the cold-adapted species from the Mammuthus-Coelodonta faunal complex like Ursus ingressus, Panthera spelaea spelaea, Coelodonta antiquitatis, Bison priscus, and Megaloceros giganteus disappeared. During the second phase, at the latest Pleistocene and the Holocene boundary, all the species of the Mammuthus-Coelodonta faunal complex still not became extinct. Several species from this assemblage disappeared later in the Holocene. It should be noted that the role of the human in the changes of faunal complexes and species extinctions during the Late Pleistocene and the Holocene in the Sudety Mts cannot be so far demonstrated.

The study of past environments, their ecology, and detailed changes through time has become an important task of environmental science. Records of paleoenvironment usually vary between regions owing to different influences of local climate, vegetation, relief, and depositional processes. Therefore, studying local sequences thoroughly allows paleoenvironmental and paleoecological reconstructions for particular regions, but it also provides important data that complement the global record. The Żarska Cave is an exceptional site, which owing to its thick and undisturbed Holocene sediments with very rich paleobotanical and paleozoological materials has become the most complete example of the uppermost Upper Pleistocene and Holocene cave deposits in the Polish uplands. The aim of our study was to understand paleoenvironmental changes in southern Poland, from the late Glacial to the late Holocene, which has been targeted by use of a detailed geological analysis accompanied by analysis of a wide range of paleobotanical, paleozoological, and archeological assemblages. All the results obtained have permitted characterization of the paleoenvironmental changes occurring in the area of the Polish Jura during the last >15 ka years. A particularly well-represented sequence covers the Allerød interstadial, which revealed the presence of forests with associated shade-loving mollusks and rodents. The beginning of the Holocene was clearly identified with an increase of shaded forest habitats, which developed in a still relatively cold climate with continental features, and with the first appearance of mesophilous deciduous trees. During the middle Holocene, unusual evidence for maple forests is documented, which developed before the formation of beech forests, typical for the late Holocene. The obtained sequence has great significance not only for the Polish Jura region, but also has wider implications for southern Poland and the vast area of the northern Carpathian foreland.

The Micoquian is the broadest and longest enduring cultural facies of the Late Middle Palaeolithic that spread across the periglacial and boreal environments of Europe between Eastern France, Poland, and Northern Caucasus. Here, we present new data from the archaeological record of Stajnia Cave (Poland) and the paleogenetic analysis of a Neanderthal molar S5000, found in a Micoquian context. Our results demonstrate that the mtDNA genome of Stajnia S5000 dates to MIS 5a making the tooth the oldest Neanderthal specimen from Central-Eastern Europe. Furthermore, S5000 mtDNA has the fewest number of differences to mtDNA of Mezmaiskaya 1 Neanderthal from Northern Caucasus, and is more distant from almost contemporaneous Neanderthals of Scladina and Hohlenstein-Stadel. This observation and the technological affinity between Poland and the Northern Caucasus could be the result of increased mobility of Neanderthals that changed their subsistence strategy for coping with the new low biomass environments and the increased foraging radius of gregarious animals. The Prut and Dniester rivers were probably used as the main corridors of dispersal. The persistence of the Micoquian techno-complex in South-Eastern Europe infers that this axis of mobility was also used at the beginning of MIS 3 when a Neanderthal population turnover occurred in the Northern Caucasus.

The Middle Pleistocene was a period of dynamic changes in Europe. During MIS 11, a number of modern mammal taxa appeared and environmental conditions remained warm and favourable for a relatively long time. The Medzhybizh 1 locality of Ukraine dated to this very period comprises alluvial deposits with rich animal remains, which allow not only to reconstruct the fauna composition, but also to highlight the environmental conditions that dominated at this locality. A revision of the fauna of Medzhybizh 1 locality based on remains of all vertebrate groups revealed a taxonomically diverse fish community (16 species of 11 genera) dominated by cyprinids common for lacustrine or riverine assemblages. Amphibians are represented by 11 species, while the number of reptile and bird remains are less significant. Mammals are the most represented group at the locality, including small mammals (30 species), carnivorans (2 species), and ungulates (5 taxa), the latter dominated by C. elaphus. The taxonomic composition of terrestrial groups indicates temperate climate with boreal-type forests and meadows similar to cold steppe, as well as low wet areas and riparian habitats inhabited by amphibians, reptiles, insectivores, beavers, and various voles. The fish assemblage indicates a partially overgrown but well-aerated water body (lake or slow-flowing river) with sandy-silty bottom. Lithic artefacts found at the Medzhybizh 1 locality contribute to a better understanding of relationships between ancient hominins and faunas during the Middle Pleistocene of Eastern Europe., Archaeological field works at Medzhybizh were supported by the NASU state research projects 0105U001383 (2005–2009), 0109U008921 (2010–2014) and partly funded by the State Fund of Fundamental Research of Ukraine grant 0118U001457 (F77/50–2018). This research was also supported by the grant 0201/2048/18 ‘Life and death of extinct rhino (Stephanorhinus sp.) from Western Poland: a multi-proxy palaeoenvironmental approach’ financed from the funds of the National Science Centre, Poland. JvdM received support from the Spanish Ministerio de Ciencia, Inovación y Universidades (current grant numbers PGC2018-093925-B-C31 and PGC2018-095489-B-I00).

The steppe brown bear U. a. “priscus” is constant but not a common member of the Late Pleistocene paleocommunities. It is not distinct arctoid species, but a large brown bear ecomorph which lived in open environments. Instead to speleoid bears, which disappeared ca. 26-24 ka BP, arctoid bears, thanks to their ecological plasticity, were present in most of the European areas even during the cold phases. The size and diet of these bears were modified under the climate conditions and food availability. U. a. “priscus” cannot be distinguished genetically, but it differs metrically and morphologically. It was a big sized form with enlarged and broad cheek teeth. Late Pleistocene brown bears, especially those lived before the LGM were more carnivorous than the Holocene and recent brown bear. The steppe brown bear survived till the beginning of the Holocene, where the last relict populations lived around the Baltic and the North Sea decreasing in size and merging genetically with widely distributed Eurasian populations of U. a. arctos.

Coulet des Roches is a natural karst trap in Southern France. Its infilling dates back to the end of the Pleniglacial (Last Glacial Maximum, LGM) and the end of the Tardiglacial (Last Glacial, LG). Three mustelid species have been identified in this infilling: the common polecat (Mustela putorius, minimum number of individuals (MNI) = 4), the stoat (Mustela erminea, MNI = 14) and the weasel (Mustela nivalis, MNI = 48). The common polecat remains are metrically and morphologically indistinguishable from recent European specimens. The smallest mustelids are mainly represented by average-sized specimens, which are slightly smaller than extant species. A partial weasel skeleton of an extremely small pygmy weasel, regarded as a typical glacial element, was also discovered. Sexual dimorphism is strongly pronounced. Seventeen horses have been identified, corresponding to the chrono subspecies Equus ferus gallicus. The analysis of the muzzles and metapodials shows overall adaptation to cool and dry weather conditions. The ibexes are typical of Capra ibex (MNI = 15). The p3 morphology is similar to the LGM populations located on the southern side of the Durance River, with an important dilation of the metaconid, except for the oldest LGM specimen. This dilation is older on the southern side of the Durance River, as it occurs at the end of MIS 3. This difference could reflect the barrier role of the Durance River. Micromammals are abundant (mostly related to rodents and shrews; 18 genera/species; MNI = 470). The paleoecological study highlighted important and rapid climatic and environmental fluctuations throughout the sequence. As a result of climatic fluctuations, the plains constituted a corridor for the migration of temperate species to Provence during cold periods (“southern refuge zone”) and their re-immigration to Western Europe during temperate episodes. In a related and complementary way, the highland areas not only played a natural role as a geographical barrier, but also constituted a refuge zone during interglacial episodes for some micromammal species originating from northern and eastern parts of Europe (“cryptic southern refugia”).

This study analyzed size changes in the course of the time among European Middle and Late Pleistocene lions. The general decreasing size as a tendency in cave lion evolution is confirmed. The whole time span of lion presence in Europe was divided into four main periods. The first period covers Middle and late Middle Pleistocene (MIS 19-17 to MIS 7-6) and is characterized by the presence of very large individuals with somewhat primitive morphology. It might be cautiously said that lions in that time were comparatively large throughout the Middle and late Middle Pleistocene. The second period included the last part of the late Middle and the beginning of the Late Pleistocene (MIS 6-5). This period is documented by a mixed presence of large individuals with somewhat primitive features together with smaller, evolutionarily more advanced dentition lions. The third period covers the first part of the last glacial, from MIS 5 to the beginning of MIS 3. For this period, the occurrence of moderate sized specimens with evolutionarily advanced dentition is documented. The last period began with dramatic population decline and genetic variability reduction. It lasted from MIS 3 and 2, and within it size drops sharply. Among moderate sized specimens, very small lions with somewhat lesser posture also appeared. Asian or African affinities as a result of a new migration event for those dwarf lions could not be ruled out. Size decrease showed that Panthera spelaea was a dynamically evolved species. Thus, the size does not seem to be a reliable criterion in determining the age of cave lion findings. The general overview is complicated by the great sexual dimorphism, local evolution and extinction, climatic conditions, and migrations. Size changes in P. spelaea evolution cannot be used as a useful biochronological tool.

The deposits of Biśnik Cave yielded numerous bear remains from sediments dated to the MIS 8–MIS 3 interval. This situation allowed examination of the paleoecology of Ursus spelaeus over time, compared with two other species of bears: Ursus deningeri and Ursus arctos, also present in fossil material from Biśnik Cave. The stable isotope ratios (δ13C, δ18O) in tooth enamel were applied in combination with examination of seasonal deposition of dental cementum. The δ13C values showed the diet of each bear species stayed in the range of C3 plants. Results for U. spelaeus showed a wider range of δ13C values than for U. deningeri or U. arctos. The values are relatively negative in comparison to fossil bears from other European sites. Low δ13C values observed in bears from Biśnik Cave could be linked to a canopy effect and document a forested environment for these bears. No correlation between δ18O and δ13C values was noted. The cementum analysis revealed that season of death of all species was winter and all studied specimens died during hibernation. The highest mortality concerned mostly individuals below 4 years old and the highest individual aged was U. deningeri.

Climate changes that occurred during the Late Pleistocene have profound effects on the distribution of many plant and animal species and influenced the formation of contemporary faunas and floras of Europe. The course and mechanisms of responses of species to the past climate changes are now being intensively studied by the use of direct radiocarbon dating and genetic analyses of fossil remains. Here, we review the advances in understanding these processes by the example of four mammal species: woolly mammoth (Mammuthus primigenius), cave bear (Ursus spelaeus s. l.), saiga antelope (Saiga tatarica) and collared lemmings (Dicrostonyx ssp.). The cases discussed here as well as others show that the migrations, range shifts and local extinctions were the main responses to climate changes and that the dynamics of these climate driven processes were much more profound than it was previously thought. Each species reacted by its individual manner, which depended on its biology and adaptation abilities to the changing environment and climate conditions. The most severe changes in European ecosystems that affected the largest number of species took place around 33–31 ka BP, during the Last Glacial Maximum 22–19 ka BP and the Late Glacial warming 15–13 ka BP.

The Borsuka Cave is located in the southern part of Krakow-Czestochowa Up- land, about 20 km west of Krakow. During excavations conducted in 2008-2010 a very rare and interesting faunal assemblage from layer VI was found, dating to the Upper Pleniglacial. Among cold steppe-tundra or taiga species such as Rangifer tarandus, Vulpes alopex, Equus sp. or Coelodonta antiquitatis taxa adapted to forest environment were also found. Associated with them we found snails, such as Ena montana, Aegopi- nella pura and Perforatella incarnata; insectivores, like Sorex araneus, carnivores, such as Martes martes, Meles meles and Lynx cf. lynx; ungulates, like Alces alces and Bos primigenius and, among rodents, Clethrionomys glareolus, Apodemus sylvaticus/flavicol- lis and Castor fiber. This assemblage is the first from southern Poland during this time pe- riod to comprise such relatively rich material, and indicates the presence of forest adapted species at the end of the Upper Plenivistulian. No similar assemblages are known from other caves from the Krakow-Czestochowa Upland, and this suggests that during Late Pleistocene in a limited area of Poland, short episodes of forest formations could appear.

The cave bear (Ursus spelaeus sensu lato) is a typical representative of Pleistocene megafauna which became extinct at the end of the Last Glacial. Detailed knowledge of cave bear extinction could explain this spectacular ecological transformation. The paper provides a report on the youngest remains of the cave bear dated to 20,930 ± 140 14C years before present (BP). Ancient DNA analyses proved its affiliation to the Ursus ingressus haplotype. Using this record and 205 other dates, we determined, following eight approaches, the extinction time of this mammal at 26,100–24,300 cal. years BP. The time is only slightly earlier, i.e. 27,000–26,100 cal. years BP, when young dates without associated collagen data are excluded. The demise of cave bear falls within the coldest phase of the last glacial period, Greenland Stadial 3. This finding and the significant decrease in the cave bear records with cooling indicate that the drastic climatic changes were responsible for its extinction. Climate deterioration lowered vegetation productivity, on which the cave bear strongly depended as a strict herbivore. The distribution of the last cave bear records in Europe suggests that this animal was vanishing by fragmentation into subpopulations occupying small habitats. One of them was the Kraków-Częstochowa Upland in Poland, where we discovered the latest record of the cave bear and also two other, younger than 25,000 14C years BP. The relatively long survival of this bear in karst regions may result from suitable microclimate and continuous access to water provided by deep aquifers, indicating a refugial role of such regions in the Pleistocene for many species.

The fossil-bearing deposits of Żabia Cave (Czestochowa Upland, Poland) yielded a diverse vertebrate fauna (75 taxa in total) of middle Early Pleistocene age. The assemblage comprises 5 amphibian, 10 reptilian and 6 bird taxa. Small mammals are represented by13 insectivorous species, 6 taxa of bats, 2 lagomorphs and 18 rodents. Large mammals include 15 species of carnivores, an unidentified horse, and 3 even-toed ungulates. The assemblage contains few Pliocene relict forms (e.g. Mioproteus wezei, Asoriculus gibberodon, Beremendia fissidens, Mimomys pitymyoides, Pannonictis ardea) and numerous Early Pleistocene newcomers (e.g. Sorex runtonensis, Ochotona zabiensis, Prolagurus ternopolitanus, early Microtus, Gulo schlosseri, Lutra simplicidens, Cervalces carnutorum). The assemblage documents migration of species associated with cool climate into Central Europe in the middle Early Pleistocene.

The wolverine Gulo gulo LINNAEUS, 1758 from the Late Pleistocene site at Kaniv: a short review of the history of the species in the Ukraine. Acta zoologica cracoviensia, 54A(1-2): 47-53. Abstract. A right fragment of the maxilla of Gulo gulo was found in the Late Pleistocene locality of Kaniv in central Ukraine. The specimen is assigned to the Late Pleistocene form because of its large size and morphological characters of teeth. Fossil remains of Gulo gulo are known from 10 localities in Ukraine, but most of them are not well dated. Palaeontological and historical records of wolverine from Ukraine are discussed.

Investigations in four natural traps from southeastern France have provided new and extensive information on the palaeoenvironment from the Last Glacial Maximum (LGM; 21,000 to 15,075 cal BP), the Late-glacial period (15,075 to 11,490 cal BP) and the beginning of Holocene (11,490 to 2835 cal BP). Radiocarbon and U/Th dates provided precise chronological data. In the Coulet des Roches, an LGM and a near complete Late-glacial period sequence were identified. The infilling preserved skeletons of large mammals, revealing a new faunal assemblage for southeastern France. For the first time, two distinct southern expansions of Dicrostonyx torquatus have been identified, correlated firstly to the LGM and secondly to the Late-glacial period. Dicrostonyx torquatus was found to be associated with Microtus oeconemus during the Oldest Dryas (15,075 to 18,270 cal BP). Morphological adaptations to the cold climate were indicated by some mammals (Vulpes vulpes, Mustela nivalis, Mustela erminea, Equus caballus gallicus). Among the birds, Bubo scandiacus and Pyrrhocorax graculus were found to be abundant. Palynological data suggested a very open landscape as well as a cold and rather dry climate. Rangifer tarandus remains were recovered from the Oldest Dryas layers of Aven des Planes. During the Allerod, a wooded environment permitted the dispersal of Cervus elaphus, Sus scrofa, Tetrao urogallus as well as reptiles and amphibians. Holocene sequences existed in these two natural traps as in Aven Souche n° 1 and n° 2. At this time, a sparsely wooded landscape covered much of the area. Cervus elaphus and Tetrao urogallus were still present with Canis lupus, Lynx lynx and Felis silvestris. Areas of open landscape were occupied by Otis tarda. During the Bronze Age (2200 to 800 cal BC) and Iron Age (800 to 50 cal BC), Aven des Planes, Aven Souche n° 1 and n° 2 were used by humans and had a sepulchral destination.

Estimates of genetic diversity and phylogenetic affiliation represent an important resource for biodiversity assessment and a valuable guide to conservation and management. We have found a new population (Jawor—JW) of the common hamster Cricetus cricetus in western Poland that is remote from the nearest populations by 235–300 km. With the objective of genetically characterizing of this population, we compared it with other populations from Poland and Germany by taking into account sequences of four mitochondrial DNA genes and variation at 10 microsatellite loci. The JW population exhibited low levels of genetic diversity and allelic and haplotype richness, which likely reflects its extreme isolation. This factor, coupled with inbreeding and genetic drift, are major threats to JW. A neighbor-joining tree based on mtDNA haplotypes shows that JW clusters among samples representing the Central subgroup that is known from central Germany but that has not yet been identified in Poland. Findings presented here improve our understanding of the spread and diversification of the common hamster. We offer the following hypotheses to explain the observed pattern of mtDNA haplotype distribution: JW could be a byproduct of postglacial migrations or back-migrations from eastern refugia to the western part of Europe, or/and be a result of population and habitat fragmentation. We recommend translocation of individuals as an effective management strategy, both at the level of Central phylogeographic group and at the species level, to overcome the negative consequences of inbreeding and geographical isolation of the JW population.
