The palynological and sedimentological analyses on the Poggio Rosso alluvial plain sediments reveal two major climatic ﬂuctuations correlated to a glacial/interglacial cycle just before the Plio-Pleistocene boundary. The glacial phase, indicated by the expansion of herbs as well as by ephemeral streams associated with calcareous palaeosols, extends from the base of the succession and culminates close to an impressive mammalian bone accumulation dated at 1.87 Ma. The associated increasing aridity had severe consequences on the faunal communities, inducing the migration of open plain dwellers and the trapping of other residents around a few residual shrinking water bodies. A cooperative Pachycrocuta brevirostris clan acted as regulator of game populations debilitated by drought. Previous research indicates that hyenas were also the major bone accumulators. The following moister and warmer interglacial phase ca 1.83 Ma is documented by arboreal taxa and hydromorphic palaeosols in a ﬂoodplain crossed by migrating, perennial, sinuous streams. The Climatic Amplitude Method calculated mean annual temperatures around 12.5–14 C and mean annual precipitation around 800 mm, with a minimum of 400 mm during the glacial phase and 15/16–19 C and 750–1200 mm during the interglacial phase. The reconstruction reveals higher mean annual temperatures and precipitation during the interglacial as compared to the present-day climate. During the glacial, conditions were similar to today’s in all but lower precipitation values were reached during the acme drought phase just above the fossiliferous bed. Poggio Rosso documents the ecological consequences the buildup of the Apennine chain had under the effects of the latest Pliocene global climatic changes. It therefore represents one of the ﬁrst signals of the patchiness that, since then, gradually increased leading to the eventual habitat fragmentation typical of the late Pleistocene landscapes.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></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%">Costa, Augusta</style></author><author><style face="normal" font="default" size="100%">Pereira, Helena</style></author><author><style face="normal" font="default" size="100%">Oliveira, Ângelo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Influence of climate on the seasonality of radial growth of cork oak during a cork production cycle</style></title><secondary-title><style face="normal" font="default" size="100%">Ann.

A dendroclimatological approach was applied to the series of 8 complete years contained in the cork-production cycle and growth effects were removed by standardization and calculation of annual growth indices. The most important factor positively influencing diameter growth was cumulative precipitation in the growing season (January–June) and in the previous autumn and winter (October/November of the previous year–June). The monthly temperature is a less influential factor, negatively correlated with diameter growth in high summer drought (August) and positively correlated at the beginning of physiological activity (March).</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue></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%">Caritat, A</style></author><author><style face="normal" font="default" size="100%">Molinas, M</style></author><author><style face="normal" font="default" size="100%">Gutiérrez, E</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Annual cork-ring width variability of Quercus suber L. in relation to temperature and precipitation (Extremadura, southwestern Spain)</style></title><secondary-title><style face="normal" font="default" size="100%">Forest Ecology and Management</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%">cork growth</style></keyword><keyword><style  face="normal" font="default" size="100%">cork-oak</style></keyword><keyword><style  face="normal" font="default" size="100%">cork-ring chronology</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber L.</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1996</style></year></dates><volume><style face="normal" font="default" size="100%">86</style></volume><pages><style face="normal" font="default" size="100%">113-120</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">A 14 year sequence of cork-ring width chronology is correlated with rainfall and temperature data.

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>
