NORTH AMERICAN DROUGHTS OF THE MID TO LATE NINETEENTH CENTURY: A HISTORY, SIMULATION AND IMPLICATION FOR MEDIAEVAL DROUGHT

Herweijer C.; Seager R.; Cook E.R. (2006)

Unlike the major droughts of the twentieth century that are readily identified in the instrumental record, similar events in the nineteenth century have to be identified using a combination of proxy data, historical accounts ...
RAPID CLIMATE CHANGE DURING THE EARLY HOLOCENE IN WESTERN EUROPE AND GREENLAND

Prasad S.; Brauer A.; Rein B.; Negendank J.F.W. (2006)

Based on microfacies analyses of seasonally laminated varved sediments from lake Holzmaar, Germany, we report evidence of decadal-to century-scale climate variability during the early Holocene. The shifts in climate are ...

Cann J.H.; Murray-Wallace C.V.; Riggs N.J.; Belperio A.P. (2006)

Gulf St Vincent is one of a pair of elongate, triangular, shallow water embayments into the southern coast of continental Australia. From the southern floor of this embayment, within a shallow basin-like depression where ...
HOLOCENE FIRE IN THE SCOTTISH HIGHLANDS: EVIDENCE FROM MACROSCOPIC CHARCOAL RECORDS

Froyd C.A. (2006)

It has been hypothesized that the mid-Holocene decline of pine (Pinus sylvestris L.) woodland in the Scottish Highlands may have been the result of a change in the fire regime of the region. Little is known about the ...
RECONSTRUCTION OF HOLOCENE MONSOON HISTORY FROM THE PEARL RIVER ESTUARY, SOUTHERN CHINA, USING DIATOMS AND CARBON ISOTOPE RATIOS

Zong Y.; Lloyd J.M.; Leng M.J.; Yim W.W.S.; Huang G. (2006)

This study employs a multiproxy approach in the reconstruction of Holocene monsoon history from sedimentary sequences obtained from the Pearl River Estuary, southern China. A set of modern surface sediment samples were ...
A HIGH MOUNTAIN POLLEN-ALTITUDE CALIBRATION SET FOR PALAEOCLIMATIC USE IN THE TROPICAL ANDES

Rull V. (2006)

The numerical relationship between modem pollen assemblages and altitude in high mountain environments from the northern Andes is analysed, in order to found inference models that allow estimating palaeoaltitudes and ...
VARIABILITY IN NORTH ATLANTIC MARINE RADIOCARBON RESERVOIR EFFECTS AT C. AD 1000

Ascough P.L.; Cook G.T.; Church M.J.; Dugmore A.J.; Arge S.V.; McGovern T.H. (2006)

14C age measurements made on samples from three archaeological sites located on North Atlantic coasts were used to investigate the marine reservoir effect (MRE) at c. AD 1000. This is an important period within human ...
SURFACE EXPOSURE DATING OF MORAINES IN THE KROMER VALLEY (SILVRETTA MOUNTAINS, AUSTRIA)-EVIDENCE FOR GLACIAL RESPONSE TO THE 8.2 KA EVENT IN THE EASTERN ALPS?

Kerschner H.; Hertl A.; Gross G.; Ivy-Ochs S.; Kubik P.W. (2006)

10Be dating of a pronounced glacier advance (‘Kromer Stadial’) in the western part of the Silvretta Mountains (western Austria) yielded ages ranging from 8010±360 to 8690±410 years with a mean age for moraine stabilization ...
TERRESTRIAL MOLLUSC SUCCESSION AND STRATIGRAPHY OF A HOLOCENE CALCAREOUS TUFA DEPOSIT FROM THE FYLEDALEN VALLEY, SOUTHERN SWEDEN

Gedda B. (2006)

A Holocene calcareous tufa deposit in the Fyledalen Valley in southern Sweden was investigated with respect to molluscs, pollen, plant macrofossils and Coleoptera remains. The investigation recovered four mollusc species ...
A MILLENNIAL-SCALE RECONSTRUCTION OF SPRUCE BUDWORM ABUNDANCE IN SAGUENAY, QUEEBEC, CANADA

Simard I.; Morin H.; Lavoie C. (2006)

A high-resolution macrofossil analysis was conducted to reconstruct spruce budworm abundance in an 8600-year-old mire in Saguenay, QuEbec, Canada. Abundant spruce budworm (Choristoneura fumiferana [Clem.]) faeces recovered ...
ENVIRONMENTAL HISTORY OF THE DRY FOREST BIOME OF GUERRERO, MEXICO, AND HUMAN IMPACT DURING THE LAST C. 2700 YEARS

Berrio Ju.C.; Hooghiemstra H.; van Geel B.; Ludlow-Wiechers B. (2006)

Two lake sediment cores from Madre del Sur mountain range,Guerrero State, west-central Mexico were studied to examine the pastdynamics of the dry forest biome. Pollen, spores of coprophilousfungi, cyanobacteria and ...
ELASTIC BEHAVIOUR AND STRUCTURAL EVOLUTION OF TOPAZ AT HIGH PRESSURE

Gatta G.D.; Nestola F.; Ballaran T.B. (2006)

The elastic behaviour and the high-pressure structural evolution of a natural topaz, Al2.00Si1.05O4.00(OH0.26F1.75), have been investigated by means of in situ single-crystal X-ray diffraction up to 10.55(5) GPa. No phase ...
MODERN POLLEN ASSEMBLAGES FROM GRAZEDVEGETATION IN THE WESTERN PYRENEES, FRANCE: A NUMERICAL TOOL FOR MORE PRECISE RECONSTRUCTION OF PAST CULTURAL LANDSCAPES

Mazier F.; Galop D.; Brun C.; Buttler A. (2006)

Modern pollen assemblages from grazed vegetation in the Pyrenees Mountains (France) were studied with the aim of providing a calibrated model for reconstructing past pastoral activities. The modem analogues were selected ...
FOREST DYNAMICS IN THE PFYN FOREST IN RECENT CENTURIES (VALAIS, SWITZERLAND, CENTRAL ALPS): INTERACTION OF PINE (PINUS SYLVESTRIS) AND OAK (QUERCUS SP.) UNDER CHANGING LAND USE AND FIRE FREQUENCY

Bendel M.; Tinner W.; Ammann B. (2006)

Pinus sylvestris is co-dominant in many areas of eastern and northern Europe. In Switzerland, the Pfyn forest is considered to be the largest natural forest of Pinus sylvestris. Its development under changing land use ...
