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 Pleistocene lion Panthera spelaea was not a homogenous taxon; it was represented by three chronoforms. The oldest one, from the Early and Middle Pleistocene, was P. s. fossilis, the youngest was the Late Pleistocene cave lion P. s. spelaea. The intermediate form between them was P. s. intermedia. The scarcity of stratigraphically old lion made it difficult to understand the evolution of this carnivore. Therefore, we revised the fossil material of the Pleistocene lion from Polish excavation sites. The analysis revealed the presence of P. s. fossilis in 7 sites: Tunel Wielki, Poludniowa, Wschodnia, Draby, Biśnik, Deszczowa and Wierzchowska Gorna caves. The remains from these localities significantly differed in their average size and teeth proportions from the nominate younger chronoform, i.e. the cave lion. Using this material and all other available data, we compared the lion remains grouped into four palaeoclimate periods: MIS 17-12, MIS 11-9, MIS 8-6 and MIS 5-2. We found significant time-related trends in many morphometric features of dentition and limb bones. Between the first two periods, the lion became larger but from MIS 8, it gradually decreased in size. The teeth showed a much greater rate of changes than the metapodial bones, which in turn were characterised by more heterogeneous and mosaic evolution. The changes observed in the fossil material can result from in situ evolution of lion populations occupying Europe or immigration and replacement of the native forms by those from other regions, for example Asia.

The Crimean Mountains are well known from the abundance of Middle and Late Palaeolithic sites and palaeontological remains recovered from cultural layers in caves and rockshelters. The fossil-bearing deposits of Emine-Bair-Khosar Cave, located at the elevation of 1000 m on the Chatyrdag Plateau, yielded a very diverse and numerous vertebrate remains that widen the knowledge of Late Pleistocene faunal diversity in the Crimea. The assemblage comprised in total almost 50 species of vertebrates. Studies included geomorphological, geological and stratigraphic analyses as well AMS 14C dating. Faunal remains were present in ten palaeontological sites. The main bone accumulation (section Ba2) was deposited during Middle Valdai or Vytachiv (MIS 3) interstadial, and including a long time gap, to the end of the Pleistocene and the Holocene. Comparison of the Emine-Bair-Khosar fauna with vertebrate faunas of other Crimean sites showed a remarkable stability in the faunal composition and frequency during the whole MIS 3 interstadial. Steppe and other open-country species dominated in the compared assemblages, while boreal-tundra species were far less numerous. Inhabitants of forests, including red deer and some rodents, were stable members of fossil assemblages.

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.

Received: 21 January 2011 Accepted: 15 June 2011 MARCISZAK A., KOVALCHUK O. 2011. 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.

The first leopard (Panthera pardus) from the Pleistocene of Poland was discovered in the sediments of Biœnik Cave. Bones show morphological and metric similarity to large specimens of the modern leopard. This finding provides evidence for the existence of the leopard in late Middle and early Late Pleistocene in Europe north of the Carpathian arch.

Two forms of cave lion Panthera spelaea GOLDFUSS, 1810: Middle Pleistocene Panthera spelaea fossilis REICHENAU, 1906 and Upper Pleistocene Panthera spelaea spelaea GOLDFUSS, 1810 are reported from the Bisnik Cave (Czþ estochowa Upland, Southern Poland). A detailed examination of tooth (particularly carnassials) and mandible morphology provides a basis to discuss the inferred size trend from the earlier, bigger P. s. fossilis to the smaller and more recent chronosubspecies P. s. spelaea. The original acquisition labels and detailed stratigraphy make it possible to place these finds within an updated stratigraphic and biochronological framework. The cave lion remains from the Bisnik Cave show that the large, primitive form fossilis was replaced by the more specialized form spelaea.

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.

Le Coulet des Roches et l'aven des Planes sont deux avens-pièges vauclusiens. Le premier a fourni des informations inédites sur la faune et le paléoenvironnement de la fin du Pléistocène supérieur et du début de l'Holocène, de 36 060 ± 620 Cal BP à 3 610 ± 40 cal BP. Les dépôts sédimentaires du Dernier Maximum Glaciaire et du Dernier Glaciaire sont majoritaires, livrant une faune froide, jusque-là inconnue en Provence, constituée de squelettes complets de grands et petits mammifères, et d'oiseaux. Un niveau argileux daté de 26 700-26 250 cal BP, résultant d'un lessivage de sédiments absents aujourd'hui à proximité immédiate de l'aven, fournit des fossiles d'invertébrés et de vertébrés marins du Cénozoïque et du Mésozoïque. L'aven des Planes fournit des compléments d'informations sur le Dernier Glaciaire. C'est à ce jour le seul site de Provence à avoir livré les squelettes complets de deux rennes.

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.
