The lower part of one of these sequences, corresponding to the late- glacial period, has been published previously. The first third of the Post-glacial is characterized by very particular forest dynamics, namely the absence of a role for deciduous Quercus and Corylus, the presence of mesophilous vegetation types dominated by Taxus, and the major forest role of Erica arborea at lower and mean altitude. At about 7440 cal BP, the occurrence of a major anthropogenic action brought about significant changes in the vegetation, notably an increase of deciduous Quercus and the expansion of Quercus ilex. Later, three major human-induced events are identified: the first, at about 2290 cal BP, is the cause of a short local expansion of Abies; the second, at about 1150 cal BP, is the degradation of deciduous forests to the benefit of Fagus; the third, at about 310 cal BP, corresponds to the disappearance of Fagus and its replacement by Pinus. Pollen data indicate that Q. ilex, Abies and Fagus are not indigenous in Corsica but spread there during the Postglacial ; this probably took place at about 6980 cal BP for Q. ilex.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">REILLE, M</style></author><author><style face="normal" font="default" size="100%">Gamisans, J</style></author><author><style face="normal" font="default" size="100%">De Beaulieu, J.-L.</style></author><author><style face="normal" font="default" size="100%">ANDRIEU, V</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The late-glacial at Lac de Creno (Corsica, France): a key site in the western Mediterranean basin</style></title><secondary-title><style face="normal" font="default" size="100%">New Phytologist</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Lac de Creno (Corsica)</style></keyword><keyword><style  face="normal" font="default" size="100%">Late-glacial</style></keyword><keyword><style  face="normal" font="default" size="100%">pollen spectra</style></keyword><keyword><style  face="normal" font="default" size="100%">western Mediterranean basin</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year></dates><publisher><style face="normal" font="default" size="100%">Blackwell Publishing Ltd</style></publisher><volume><style face="normal" font="default" size="100%">135</style></volume><pages><style face="normal" font="default" size="100%">547-559</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The lower part (460–650 cm) of a lacustrine sequence from Lac de Creno, Corsica (1310 m) is analysed on the basis of 68 pollen spectra and with the support of 10 14C dates (including nine A.M.S. dates). This sequence, which extends from the end of the Würm to the beginning of the Postglacial, reveals a complete late-glacial. The absence of forest dynamics during the late glacial Interstadial in Corsica is a real mystery. Pollen data clearly suggest that Pinus laricio (=Pinus nigra Arnold ssp. laricio Maire) and perhaps other tree species did not exist in Corsica at that time.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pons, A</style></author><author><style face="normal" font="default" size="100%">REILLE, M</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The holocene- and upper pleistocene pollen record from Padul (Granada, Spain): A new study</style></title><secondary-title><style face="normal" font="default" size="100%">Palaeogeography, Palaeoclimatology, Palaeoecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">climatic fluctuations</style></keyword><keyword><style  face="normal" font="default" size="100%">Holocene</style></keyword><keyword><style  face="normal" font="default" size="100%">Padul</style></keyword><keyword><style  face="normal" font="default" size="100%">Pollen analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetation history (PG)</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1988</style></year></dates><volume><style face="normal" font="default" size="100%">66</style></volume><pages><style face="normal" font="default" size="100%">243-263</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Two borings were made at the site of Padul (Granada). Pollen analysis of 200 spectra from two successive sequences, 14.8 and 8 m deep, enables a description of the vegetational and climatic history of this region, the most southern one in Europe, from Early Würmian times. The chronology is supported by twenty-one 14C dates. Original equivalents are found for the great European Prewürm interstadials. A markedly arid though thermically not extreme episode, exactly equivalent to stage 4 of the marine isotopic stratigraphy, closes this relatively temperate period. The middle part of the Last Glacial shows climatic fluctuations that are poorly characterized, as is often the case in Europe for this period. A long section, very probably corresponding to the complete Last Pleniglacial, does not show any climatic amelioration. Towards 15,000 yr B.P. a change in the diagram is noted that can only be interpreted as reflecting a larger expansion of a regional steppe cover. This event, also reported on three occasions in southeast France, marks the beginning of the Oldest Dryas. The climatic amelioration of ca. 13,000 yr B.P. is far more pronounced here than anywhere else in Europe, whereas that at 10,000 yr B.P. is not so clearly marked. This unexpected result may be accounted for by the fact that Padul is the first continental site so far south and so near Pleniglacial refuges to be known: on the other hand, this result is consistent with what is known from oceanic isotopic stratigraphy. A quite new late-glacial and Holocene vegetational history is revealed, characterized by the early appearance and dominance of Quercus ilex oak forests of a southern type and the early occurrence of Quercus suber and Olea: it is the first account of a complete history of the postglacial reafforestation in a region with a modern semi-arid mediterranean climate. From the palaeoclimatic point of view, it shows that the hot and humid Holocene optimum was attained slightly before 8000 yr B.P. and that the Holocene climatic fluctuations were of but small amplitude.</style></abstract></record></records></xml>
