Journal ArticleDOI
Quaternary refugia of north european trees
TL;DR: The survival of these trees in southern Europe through a warm stage may be at least as important for long-term Qua- ternary survival in Europe as survival during a cold stage.
Journal ArticleDOI
Buffered tree population changes in a quaternary refugium: evolutionary implications.
TL;DR: A high-resolution pollen record from western Greece shows that the amplitude of millennial-scale oscillations in tree abundance during the last glacial period was subdued, with temperate tree populations surviving throughout the interval, providing evidence for the existence of an area of relative ecological stability.
Journal ArticleDOI
The last 1.35 million years at Tenaghi Philippon: revised chronostratigraphy and long-term vegetation trends
TL;DR: In this paper, a new marine-terrestrial correlation is proposed to examine the long-term behavior of individual taxa and vegetation trends within the context of global climate changes, in terms of orbital and suborbital variability.

TL;DR: In this article, the authors identify eleven interglacials in the last 800,000 years, a result that is robust to alternative definitions, such as the onset of an interglacial (glacial termination) seems to require a reducing precession parameter (increasing Northern Hemisphere summer insolation), but this condition alone is insufficient.

TL;DR: The most detailed proxy record of interglacial climate is found in the Vostok ice core where the temperature reached current levels 132,000 yr ago and continued rising for another two millennia as discussed by the authors.
