Oxbow lake deposits of the Neris River at the Valakupiai site in Vilnius (Lithuania) have been studied by dif- ferent methods including radiocarbon dating. A timescale was attained for the development of the oxbow lake and climatic events recorded in the sediments. 14C dates obtained for 24 samples cover the range 990–6500 BP (AD 580 to 5600 BC). Medieval human activity was found in the upper part of the sediments. Mollusk fauna found in the basal part of the terrace indicate contact between people living in the Baltic and the Black Sea basins. Mean rates were calculated for erosion of the river and for accumulation during the formation of the first terrace. INTRODUCTION This work presents the results of radiocarbon dating of samples collected at the Valakupiai site, near Vilnius in eastern Lithuania (54°43′58″N, 25°18′33″E; 98.5 m asl) (Figure 1). Special attention was paid to the remnant oxbow lake in the Neris River valley and to the lake-bog deposits filling it. Detailed study of the deposits delivered specific information that enabled paleoecological recon- struction of the site, as well as a description of the geochronological evolution of the oxbow lake and accompanying climatic events.

  • Holocene Climate As Reflected by a Malacological Sequence at Verri&Res,France
    Holocene climate as reflected by a malacological sequence at Verri&res,France NICOLE LIMONDIN AND DENIS-DIDIER ROUSSEAU Limondin, N. & Rousseau, D.-D. 1991 (September): Holocene climate as reflected by a malacological Born sequence at Verrieres, France. Boreas, VOI. 20, pp. 207-229. OSIO. ISSN 03m-9483. Though numerous analyses have been made of Holocene pollen sequences, they come from similar environmental contexts, mainly peat deposits. Land snails can provide good palaeoecological and palaeoclimatical data in different drier environmental settings. The Verrieres deposits, located in the Seine Valley, southeast of Paris, provide rich and abundant malacofaunas. We compare the well-defined local biostratigraphy with other mollusc stratigraphies from Burgundy, the closest site to the studied region. Multivariate analysis of the malacofaunas indicates that temperature and moisture did not always vary in parallel during the Holocene. On the other hand, Verrieres malacofaunas reflect the main Holocene changes, as observed in the classical pollen series, confirming the reliability of the local biostratigraphy. The Younger Dryas in Verrieres was cold and dry. This was followed by the Preboreal phase, which is not well preserved at Verritres, but shows cool and humid conditions. The Boreal and Subboreal both show a cold and moist event bounded by two temperature phases. The Atlantic is also divided into two temperate phases by a cool and moist event. The Subatlantic shows temperature oscillations with cool peaks, but moisture shows a continuous trend to dryness.

Abstract: Vast amounts of fish bone lie preserved in Denmark’s soil as remains of prehistoric fishing. Fishing was particularly important during the Atlantic period (ca. 7,000-3,900 BC, i.e., part of the Mesolithic Stone Age). At this time, sea temperature and salinity were higher in waters around Denmark than today. Analyses of more than 100,000 fish bones from various settlements from this period document which fish species were common in coastal Danish waters at this time. This study provides a basis for comparing the fish fauna in the warm Stone Age sea with the tendencies seen and predicted today as a result of rising sea temperatures.

  • SECTION C 12 Timescales
    SECTION c 12 Timescales The timescales adopted in geomorphology fall well within the c.4.6 billion years of Earth history, with some being a mere season or even a single event. In addition to continuous timescales, discrete periods of Earth history have been utilized. Six hierarchical levels are formally defined geologically, and these embrace the external or allogenic drivers for the long-term intrinsic or autogenic processes that have fashioned the Earth’s surface, some parts of which still bear ancient traces, whereas others have been fashioned more recently or are currently active. Contemporary problems demand attention to be given to recent timescales, the Quaternary and the Holocene, although these are less formally partitioned. Geomorphology- focused classifications have also been attempted with short, medium and long timescales conceived in relation to system states. An outstanding chal- lenge is to reconcile research at one timescale with results from another.

  • The Ulmus Fall at the Transition Atlanticum-Subboreal in Pollen Diagrams 1
    Palaeogeography, Palaeoclimatology, Palaeoecology Elsevier Publishing Company, Amsterdam - Printed in The Netherlands THE ULMUS FALL AT THE TRANSITION ATLANTICUM-SUBBOREAL IN POLLEN DIAGRAMS 1 H. A. TEN HOVE g Division of Palaeobotany and Pollenmorphology, Botanical Museum and Herbarium, Utrecht (The Netherlands) (Received September 26, 1968) SUMMARY The views of previous authors on the elm fall, especially backgrounded by TAUBER'S (1965) theory on differential pollen dispersion, are discussed. Five possible explanations are given: climate, competition and edaphical factors, human influence, diseases, selective pollen filtering. For the time being the present author concludes that the most probable explanation for the elm fall is human influence, eventually in interaction with a change in climate. Depending on local, edaphic and ecological conditions, the various factors which may be held responsible for the elm fall, are probably of unequal importance for different regions. INTRODUCTION Following JESSEN (1934) and IVERSEN (1941) most pollenstratigraphers put a zone-boundary at the considerable fall of Ulmus at the end of the Atlantic (zone VIia/VIlb: MITCHELL, 1941; GODWIN, 1948; JESSEN, 1949; zone VII/VIII: JESSEN, 1938; FIRBAS, 1949). The Subboreal thus is defined solely in terms of vegetation development (compare also WATERBOLK, 1954). Many 14C dates indicate that the Ulmus fall occurred between 3,900 B.C. and 2,600 B.C.; 50~ of these dates comprise the period between 3,150 B.C. and 3,350 B.C. GODWIN (1960) and NILSSON (1964) summarized all available dates. The Ulmus fall In the following part five explanations of the elm fall, that were expounded in the past, are discussed.

Americo Vespuccio s/n, 41092, Sevilla, Spain A B S T R A C T Keywords: Iberomys The corological evolution of the species of the subgenus Iberomys and, specifically, of Microtus cabrerae, Microtus cabrerae are described. Iberomys appeared in the Iberian Peninsula during the Lower Pleistocene and then reached Pleistocene southern France and Italy during the Middle Pleistocene. M. cabrerae established itself as an Iberian Holocene endemic during the final glacial period and subsequently occupied South-Eastern France. This latter Biogeography population and those found along the Mediterranean coast survived until the Subatlantic period. Thus, it Conservation is concluded that Iberomys is endemic to the European sector of the western Mediterranean Basin, but once was found over much more of the Iberian Peninsula, Italy and France. The Iberian Peninsula is, nevertheless, fundamental in its life history as its evolutionary centre and the origin of expansions into other areas. On the other hand, it is possible to locate the centre of origin of the subgenus Iberomys at a regional scale (the Iberian Peninsula) and adapt its evolutionary cycle to a Symmetrical Model. The contraction of the range of M. cabrerae during the Holocene is not related to the Subboreal climatic crisis; rather, it took place during the Subatlantic and could be related to the expansion of agriculture, which probably destroyed many of its habitats.

  • Exploring the Early Anthropocene Burning Hypothesis and Climate-Fire Anomalies for the Eastern U.S
    Journal of Sustainable Forestry, 34:30–48, 2015 Copyright © Taylor & Francis Group, LLC ISSN: 1054-9811 print/1540-756X online DOI: 10.1080/10549811.2014.973605 Exploring the Early Anthropocene Burning Hypothesis and Climate-Fire Anomalies for the Eastern U.S. MARC D. ABRAMS1 and GREGORY J. NOWACKI2 1Department of Ecosystem Science and Management, Penn State University, University Park, Pennsylvania, USA 2USDA Forest Service, Eastern Regional Office, Milwaukee, Wisconsin, USA This review explores the long-term role of climate versus human activity on vegetation and fire dynamics in the eastern U.S. Early Holocene warming resulted in a conversion of Picea (boreal) to temperate Quercus and Pinus forests when indigenous populations were sparse but charcoal abundances were relatively high, under- scoring the importance of climate. Pyrogenic trees also dominated during the middle Holocene Thermal Maximum period, associated with increasing indigenous populations and high charcoal abun- dance on most sites. During Neoglacial Cooling (3300 to 150 BP) charcoal levels and pyrogenic trees remained high in the central and southern regions apparently due to Native American and early European burning trumping colder climate. In northern regions, oak-pine and charcoal abundance were distributed on intermit- tent dry and/or Native American sites. High levels of charcoal and pyrogenic species during the early Holocene and Neoglacial Cooling represent important anomalies in the ecological history of the eastern U.S. While the importance of warmer and drier climate is evident throughout, the Early Anthropocene burning hypothesis is plausible for the eastern U.S. where extensive lightning fires are rare, outside of the southeast coastal plain.

  • Paleoclimatic Implications of Pleistocene Stratigraphy in the Mediterranean Area*
    PALEOCLIMATIC IMPLICATIONS OF PLEISTOCENE STRATIGRAPHY IN THE MEDITERRANEAN AREA* Karl W. Butzer DepartmeTat of Geography, University of Wisconsin, Madison, Wis. Introduction Studies in climatic variation may consider both the causes of indicated climatic changes and the patterns of such changes. Often, however, the pat- terns are neglected, and far-reaching conclusions are drawn on the basis of dis- integrated and sporadic evidence. This is of course inevitable in a field of research embracing several distinct disciplines. It is nevertheless necessary to elaborate on the distribution of climatic anomalies both in time and space if a reliable perspective of general circulation mechanisms is to be obtained. Analyses of recent climatic fluctuations registered within the instrumental record have made considerable progress in this channel lately. In the Pleisto- cene, however, almost all interpretative study has made use of hopelessly in- adequate schemata of glacial, interglacial, pluvial, interpluvial. The major circulation changes of the Quaternary were anything but a simple expansion or contraction of climatic belts. The differential variation of the various cli- matic elements at any one locality has proved to be astoundingly complex whenever detailed evidence became available. Consequently the following materials will be devoted to a brief summary of the patterns of climatic evolution in the zone of overlap between the subtropi- cal cells of high pressure and the circumpolar westerlies in the general area of the Mediterranean Basin. Outlining the earth science evidence involved, several climatic patterns, related to specific types of “glacial” and “intergla- cial” circulation of the atmosphere, will be discussed. The provisional results presented here were obtained during various field sessions in the Near East and Mediterranean area since 1956, and much of the material has not yet received publication.
