THE IMPACT OF ANCIENT CIVILIZATION ON THE NORTHEASTERN CHINESE LANDSCAPE: PALAEOECOLOGICAL EVIDENCE FROM THE WESTERN LIAOHE RIVER BASIN, INNER MONGOLIA

Li Y.Y.; Willis K.J.; Zhou L.P.; Cui H.T. (2006)

The Western Liaohe River Basin in northeastern China is one of the cradles of ancient Chinese civilization. Archaeological records from this region indicate that human occupation began about 8000 years ago and that agriculture ...
DETECTING DIFFERENCES IN VEGETATION AMONG PAIRED SITES USING POLLEN RECORDS

Sugita Sh.; Parshall T.; Calcote R. (2006)

The ‘Qualitative Assessment of Difference’ method (QAD) is proposed to objectively detect differences in the relative abundance of vegetation between paired sites using pollen percentages. This method corrects for ...
LATE-HOLOCENE VEGETATION AND FIRE HISTORY FROM FERRY LAKE, NORTHWESTERN WISCONSIN, USA

Lynch E.A.; Calcote R.; Hotchkiss S. (2006)

We used charcoal and fossil pollen to investigate how fire, vegetation and climate have interacted over the past 2300 years at Ferry Lake, located on a sand plain in northwestern Wisconsin. Pollen analysis shows a rapid ...
HOLOCENE PALAEOENVIRONMENTS AND CHANGE AT THREE-QUARTER MILE LAKE, SILVER PLAINS STATION, CAPE YORK PENINSULA, AUSTRALIA

Luly J.G.; Grindrod J.F.; Penny D. (2006)

Pollen and diatom analyses of organic sediments from Three-Quarter Mile Lake, a perched lake on Cape York Peninsula, north Queensland, indicate that significant changes in vegetation and hydrology occurred during the ...
FIRE-FUEL-CLIMATE LINKAGES IN THE NORTHWESTERN USA DURING THE HOLOCENE

Marlon J.; Bartlein P.J.; Whitlock C. (2006)

Variations in fire regimes can be inferred from changes in the abundance of sedimentary charcoal found in lake and bog sediments. When analysed with pollen data, inferences can be made about past vegetation dynamics and ...
MIDDLE-TO LATE-HOLOCENE MOISTURE CHANGES IN THE DESERT OF NORTHWEST NAMIBIA DERIVED FROM FOSSIL HYRAX DUNG POLLEN

Gil-Romera G.; Scott L.; Marais E.; Brook G.A. (2006)

New pollen results and radiocarbon dating from fossil hyrax middens derived from the edge of the northern Namib Desert address the shortage of continental palaeobotanical evidence in arid Namibia by providing evidence for ...
AN EXPLORATORY METHOD TO DETECT TEPHRAS FROM QUANTITATIVE XRD SCANS: EXAMPLES FROM ICELAND AND EAST GREENLAND MARINE SEDIMENTS

Andrews J.T.; Eberl D.D.; Kristjansdottir G.B. (2006)

Tephras, mainly from Iceland, are becoming increasingly important in interpreting leads and lags in the Holocene climate system across NW Europe. Here we demonstrate that Quantitative Phase Analysis of x-ray diffractograms ...
CLIMATE CHANGE AND COASTAL HYDROGRAPHIC RESPONSE ALONG THE ATLANTIC IBERIAN MARGIN (TAGUS PRODELTA AND MUROS RIA) DURING THE LAST TWO MILLENNIA

Lebreiro S.M.; FrancEs G.; Abrantes F.F.G.; Diz P.; Bartels-JOnsdOttir H.B.; Stroynowski Z.N.; Gil I.M.; Pena L.D.; Rodrigues T.; Jones P.D.; Nombela M.A.; Alejo I.; Briffa K.R.; Harris I.; Grimalt J.O. (2006)

The Tagus Prodelta (W Portugal) and the Muros RIa (NW Spain) are areas of high deposition rates registering high-resolution palaeoclimatic records for western Iberia. We compare the climatic conditions of the two areas ...
POSTGLACIAL PALAEOCEANOGRAPHY IN THE SKAGERRAK

Gyllencreutz R.; Backman Ja.; Jakobsson M.; Kissel C.; Arnold E. (2006)

Crucial periods of change in the latest glacial to early-Holocene palaeogeographic and palaeoceanographic evolution in the Skagerrak region are portrayed in four time-slice maps on a calibrated age scale at 14.0 kyr, 11.2 ...
LATE HOLOCENE COASTAL HYDROGRAPHIC AND CLIMATE CHANGES IN THE EASTERN NORTH SEA

Hebbeln D.; Knudsen K.L.; Gyllencreutz R.; Kristensen P.; Klitgaard-Kristensen D.; Backman Ja.; Scheurle C.; Jiang H.; Gil I.; Smelror M.; Jones Ph.D.; Sejrup H.P. (2006)
FIRST CROSS-MATCHED FLOATING CHRONOLOGY FROM THE MARINE FOSSIL RECORD: DATA FROM GROWTH LINES OF THE LONG-LIVED BIVALVE MOLLUSC ARCTICA ISLANDICA

Scourse Ja.; Richardson Ch.; Forsythe G.; Harris Ia.; Heinemeier Ja.; Fraser N.; Briffa K.; Jones Ph. (2006)

Integrated understanding of phasings within the climate system over the last glacial cycle, and at higher frequencies, is inhibited because no absolute timescale for the marine environment currently exists. This precludes ...
MODELLING RIVER DISCHARGE AND PRECIPITATION FROM ESTUARINE SALINITY IN THE NORTHERN CHESAPEAKE BAY: APPLICATION TO HOLOCENE PALAEOCLIMATE

Saenger C.; Cronin T.; Thunell R.; Vann Ch. (2006)

Long-term chronologies of precipitation can provide a baseline against which twentieth-century trends in rainfall can be evaluated in terms of natural variability and anthropogenic influence. However, there are relatively ...
HOLOCENE BISON IN THE GREAT BASIN, WESTERN USA

Grayson D.K. (2006)

Bison (Bison bison) were widespread in the eastern and northern parts of the Great Basin (the area of internal drainage in the arid western USA) during the late Holocene, particularly after 1600 14Cyr BP. However, of the ...
LOCATING THE BOUNDARY BETWEEN THE PLEISTOCENE AND THE HOLOCENE IN CHINESE LOESS USING LUMINESCENCE

Lai Zh.P.; Wintle A.G. (2006)

A detailed chronology has been obtained for a loess section at Yuanbao, situated at the northwestern edge of the Chinese Loess Plateau. The ages were obtained by the measurement of the optically stimulated luminescence ...
CHRONOLOGICAL FRAMEWORK FOR THE LATEGLACIAL POLLEN AND MACROFOSSIL SEQUENCE IN THE PIRIN MOUNTAINS, BULGARIA: LAKE BESBOG AND LAKE KREMENSKO-5

Stefanova I.; Atanassova Ju.; Delcheva M.; Wright H.E. (2006)

The sediments of numerous cirque lakes in the Pirin Mountains have yielded several generalized pollen diagrams, but low stratigraphic and temporal resolution has hampered detailed reconstruction of the vegetational history, ...
SHORELINES IN THE SAHARA: GEOMORPHOLOGICAL EVIDENCE FOR AN ENHANCED MONSOON FROM PALAEOLAKE MEGACHAD

Drake N.; Bristow Ch. (2006)

The Sahara Desert is the most extensive desert on Earth but during the Holocene it was home to some of the largest freshwater lakes on Earth; of these, palaeolake Megachad was the biggest. Landsat TM images and Shuttle ...
HOLOCENE EVOLUTION OF THE HAIFA BAY AREA, ISRAEL, AND ITS INFLUENCE ON ANCIENT TELL SETTLEMENTS

Zviely D.; Sivan D.; Ecker A.; Bakler N.; Rohrlich V.; Galili E.; Boaretto E.; Klein M.; Kit E. (2006)

The geographical evolution of Haifa Bay and Zevulun Plain, Israel, from the late Pleistocene to the Holocene, is based on detailed analysis of drilled cores. At the beginning of the Holocene the Bay area was still under ...
HOLOCENE CHANGES IN SEA LEVEL AND COASTAL ENVIRONMENTS ON RAROTONGA, COOK ISLANDS, SOUTH PACIFIC OCEAN

Moriwaki H.; Chikamori M.; Okuno M.; Nakamura T. (2006)

The Holocene coastal plain of the island of Rarotonga, characterized by beach ridges and swamps, is the best developed of the Cook Islands group which lies in eastern Polynesia. Using geomorphic mapping, excavation and ...
STABLE-CARBON ISOTOPE COMPOSITION OF POACEAE POLLEN: AN ASSESSMENT FOR RECONSTRUCTING C3 AND C4 GRASS ABUNDANCE

Nelson D.M.; Hu F.Sh.; Michener R.H. (2006)

Plants using the C3 and C4 photosynthetic pathways differ in carbon-isotope composition, and this difference offers a means to estimate the relative abundance of these two functional groups in the palaeorecord. We report ...
