Compositional turnover and variation in Eemian pollen sequences in Europe
Volcanic ash layers illuminate the resilience of Neanderthals and early modern humans to natural hazards
Marked changes in human dispersal and development during the Middle to Upper Paleolithic transition have been attributed to massive volcanic eruption and/or severe climatic deterioration. We test this concept using records of volcanic ash layers of the Campanian Ignimbrite eruption dated to ca. 40,000 y ago (40 ka B.P.). The distribution of the Campanian Ignimbrite has been enhanced by the discovery of cryptotephra deposits (volcanic ash layers t…

Lateglacial and Holocene vegetation history at Nisi Fen and the Boras mountains, northern Greece
New pollen data from three contrasting sites in northern Greece allow an analysis of spatial and temporal patterns of vegetation change during the Holocene and Lateglacial in northern Greece. At the principal site, Nisi Fen, six cores from the thickest surficial peat deposits have yielded a detailed, composite, AMS 14 C-dated pollen record covering the period from 20000 cal. BP almost to the present-day. Cores Kp-4 and Bor-3 were taken from small…
European vegetation during Marine Oxygen Isotope Stage-3
European vegetation during representative “warm” and “cold” intervals of stage-3 was inferred from pollen analytical data. The inferred vegetation differs in character and spatial pattern from that of both fully glacial and fully interglacial conditions and exhibits contrasts between warm and cold intervals, consistent with other evidence for stage-3 palaeoenvironmental fluctuations. European vegetation thus appears to have been an integral compo…
Last Interglacial Climates
The last interglacial, commonly understood as an interval with climate as warm or warmer than today, is represented by marine isotope stage (MIS) 5e, which is a proxy record of low global ice volume and high sea level. It is arbitrarily dated to begin at approximately 130,000 yr B.P. and end at 116,000 yr B.P. with the onset of the early glacial unit MIS 5d. The age of the stage is determined by correlation to uranium–thorium dates of raised cora…
Duration of Last Interglacial Conditions in Northwestern Greece
A new astronomical calibration method for long pollen records from southern Europe is applied to the last interglacial interval of the Ioannina sequence, northwestern Greece. This shows that the last interglacial in this region, as defined by the presence of forest communities, lasted ca. 15,500 yr, from 127,300 to 111,800 yr B.P. Interglacial conditions developed within marine isotope substage (MIS) 5e and persisted into MIS 5d, lagging changes …
Combined Marine Proxy and Pollen Analyses Reveal Rapid Iberian Vegetation Response to North Atlantic Millennial-Scale Climate Oscillations
A deep-sea sediment core from the western Portuguese margin has provided a continuous, high-resolution record of millennial-scale climatic oscillations during the interval 9000–65,000 yr B.P. Pollen analysis of the same sequence allows direct, in situ assessment of the phase relationship between the North Atlantic climate system and vegetation changes on the adjacent landmass. This demonstrates for the first time that variability in NW Iberian tr…
New AMS dates from Upper Palaeolithic Kastritsa
Thirty-four years ago there appeared in the Proceedings of the Prehistoric Society the third and final paper in a series reporting the research of Eric Higgs and his colleagues into the climate, environment, and Stone Age record of north-west Greece (Higgs et al. 1967). This paper discussed two limestone rockshelters, Kastritsa and Asprochaliko, comparatively in what is now a classic example of site catchment analysis. Kastritsa, in the Pamvotis …
A revised chronological and palaeoenvironmental framework for the Kastritsa rockshelter, northwest Greece
Archaeological, palynological and palaeolimnological evidence is combined with new AMS radiocarbon dates to shed new light on a long-known, yet only partially understood, Upper Palaeolithic occupation in southeast Europe
Quaternary Refugia of North European Trees
An attempt is made to investigate the nature of cold-stage distributions for those forest trees which today extend to northern Europe. Evidence is taken from the pollen record of the present and earlier interglacials, a model of past climate, modern tree distributions, and physiography of southern Europe. The trees occupied mid-altitude sites in the mountains of southern Europe, especially in the western Balkans and Italy during the last cold sta…
