An open landscape dominated by steppe vegetation characterized the Lateglacial, so that only a modest increase of trees took place during the Allerød interstadial. The Intra Allerød Cold Period induced instability in the development of the woody communities. The Holocene forest recovery started around 11,600 cal BP, but definite forest development occurred only around 11,100 cal BP, at the end of the Preboreal Oscillation, which produced an important re-expansion of herbs. The evergreen Mediterranean vegetation was constantly present in the landscape, even during the Lateglacial cold fluctuations. A clear early Holocene increase in evergreen trees corresponds to the attainment of high and stable values in the GISP2 δ18O curve, around 10,200 cal BP.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier Ltd and INQUA</style></notes></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%">Djamali, Morteza</style></author><author><style face="normal" font="default" size="100%">Gambin, Belinda</style></author><author><style face="normal" font="default" size="100%">Marriner, Nick</style></author><author><style face="normal" font="default" size="100%">Andrieu-Ponel, Valérie</style></author><author><style face="normal" font="default" size="100%">Gambin, Timmy</style></author><author><style face="normal" font="default" size="100%">Gandouin, Emmanuel</style></author><author><style face="normal" font="default" size="100%">Lanfranco, Sandro</style></author><author><style face="normal" font="default" size="100%">Médail, Frédéric</style></author><author><style face="normal" font="default" size="100%">Pavon, Daniel</style></author><author><style face="normal" font="default" size="100%">Ponel, Philippe</style></author><author><style face="normal" font="default" size="100%">Morhange, Christophe</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Vegetation dynamics during the early to mid-Holocene transition in NW Malta, human impact versus climatic forcing</style></title><secondary-title><style face="normal" font="default" size="100%">Vegetation History and Archaeobotany</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Evergreen Pistacia</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean</style></keyword><keyword><style  face="normal" font="default" size="100%">Monsoon intensiﬁcation</style></keyword><keyword><style  face="normal" font="default" size="100%">Neolithic</style></keyword><keyword><style  face="normal" font="default" size="100%">Pollen analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Temple cultural phase</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2012///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s00334-012-0380-0</style></url></web-urls></urls><isbn><style face="normal" font="default" size="100%">0033401203800</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">A pollen diagram was constructed for the earlyto mid-Holocene transition (ca. 7350–5600 cal. B.P./5400– 3650 B.C.) from the Burmarrad ria located in NW Malta. The vegetation at ca. 7350–6960 cal. B.P./5400–5010 B.C. was characterized by an almost tree-less steppe-like open landscape. Early Holocene dry climatic conditions were most probably due to intensiﬁcation of the subtropical monsoon circulation that strengthened the subtropical anticyclonic descent over the central Mediterranean and blocked the penetration of humid air masses from the North Atlantic Ocean. At ca. 6950 cal. B.P./5000 B.C., the steppe-like vegetation was suddenly replaced by a Mediterranean evergreen forest or dense scrub dominated by Pistacia cf. lentiscus trees. This event, which has simultaneously been recorded in southern Sicily, was most probably caused by the southward shift of the ITCZ permitting the eastward movement of the North Atlantic cyclonic systems. Traces of human activities are evident in the pollen diagram since the beginning of the record but become more pronounced from the onset of the Temple Cultural Phase at ca. 6050 cal. B.P./4100 B.C. with a gradual decline of tree pollen. We suggest that the early- to mid-Holocene vegetation transformation was mainly controlled by a regional climatic change that occurred in a landscape only slightly impacted by human activities.</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%">Di Rita, Federico</style></author><author><style face="normal" font="default" size="100%">Celant, Alessandra</style></author><author><style face="normal" font="default" size="100%">Magri, Donatella</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Holocene environmental instability in the wetland north of the Tiber delta (Rome, Italy): sea-lake-man interactions</style></title><secondary-title><style face="normal" font="default" size="100%">JOURNAL OF PALEOLIMNOLOGY</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Hydrological changes</style></keyword><keyword><style  face="normal" font="default" size="100%">Plant macrofossils</style></keyword><keyword><style  face="normal" font="default" size="100%">Pollen analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Saltworks</style></keyword><keyword><style  face="normal" font="default" size="100%">Tiber delta</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">44</style></volume><pages><style face="normal" font="default" size="100%">51 - 67</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Combined analyses of pollen, seeds, woods, micro-charcoal and non-pollen palynomorphs from Stagno di Maccarese, an artificially dried out coastal basin north of the Tiber delta now occupied by the Fiumicino Airport (Rome, Italy), document marked vegetation and environmental changes during the last 8300 years. Between 8300 and 5400 cal. a BP dense mixed deciduous and evergreen forests surrounded a eutrophic freshwater basin. An abrupt change around 5400 cal. a BP marks the transition to a marshy environment, due to a lowering of the water table. An increase of cereals and micro-charcoals matches the presence of a nearby Eneolithic settlement. Between 5100 and 2900 cal. a BP there is a remarkable expansion of riparian trees, indicating an increase of the water level. Between 2900 and 2000 cal. a BP, a new development of marshlands points to a progressive lowering of the lake. After 2000 cal. a BP, during the Roman exploitation of the area, an expansion of arboreal vegetation is recorded, characterized by evergreen and deciduous oak-dominated forests, while an extensive chenopods marshland matches the presence of saltworks. On the whole, the Stagno di Maccarese area appears very unstable, due to changes in lake level, introgression of marine water, eutrophic phases, flood events, desiccations and openings of the forest vegetation.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS&lt;br/&gt;publisher: SPRINGER</style></notes></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%">Bertini, Adele</style></author><author><style face="normal" font="default" size="100%">Magi, Maurizio</style></author><author><style face="normal" font="default" size="100%">Mazza, Paul P. a</style></author><author><style face="normal" font="default" size="100%">Fauquette, Séverine</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Impact of short-term climatic events on latest Pliocene land settings and communities in Central Italy (Upper Valdarno basin)</style></title><secondary-title><style face="normal" font="default" size="100%">Quaternary International</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%">patchiness</style></keyword><keyword><style  face="normal" font="default" size="100%">Pleistocene landscapes (PG)</style></keyword><keyword><style  face="normal" font="default" size="100%">Pollen analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">sediment analysis</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S1040618209001608</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">225</style></volume><pages><style face="normal" font="default" size="100%">92 - 105</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The Upper Valdarno (Italy) Plio-Pleistocene continental deposits record the latest uniform subtropical humid conditions and the successive climatic signature of glacial/interglacial cycling. 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%">Engel, M.</style></author><author><style face="normal" font="default" size="100%">Knipping, M.</style></author><author><style face="normal" font="default" size="100%">Brückner, H.</style></author><author><style face="normal" font="default" size="100%">Kiderlen, M.</style></author><author><style face="normal" font="default" size="100%">Kraft, J.

Its signiﬁcant deceleration in midHolocene times resulted in the overcompensation by sediment yields and shoreline progradation in many areas. At the southeastern part of the lower Messenian plain (southwestern Peloponnese, Greece) detailed investigations of the Holocene stratigraphy revealed a maximum landward shoreline displacement around 3000 BC. Subsequently, aggradational processes started to form a prominent beach ridge in the late 3rd millennium BC. This is the substratum on which the early Iron Age Poseidon Sanctuary of Akovitika was founded approx. 900–850 BC. Palaeogeographic reconstructions based on 18 corings in the sanctuary and its surroundings revealed the later extension of adjacent marshland and gradual surface levelling due to seasonal inundations. These ﬁndings represent probable reasons for the abandonment of the ceremonial site around 380–350 BC. Palynological studies of the vegetational changes provide evidence for early land use and reﬂect regional settlement activities. Initial degradation and burning of woodland during late Neolithic times (c. 3500–3100 BC) as well as signiﬁcantly reduced human impact during the Protogeometric Dark Ages (c. 1060–900 BC) are proven. Additionally, local relative mean sea level (RSL) change since 5000 BC was reconstructed based on 14 C dated paralic peats.</style></abstract><issue><style face="normal" font="default" size="100%">3-4</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier B.V.</style></notes></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%">Colombaroli, Daniele</style></author><author><style face="normal" font="default" size="100%">Tinner, Willy</style></author><author><style face="normal" font="default" size="100%">van Leeuwen, Jacqueline</style></author><author><style face="normal" font="default" size="100%">Noti, Roland</style></author><author><style face="normal" font="default" size="100%">Vescovi, Elisa</style></author><author><style face="normal" font="default" size="100%">Vannière, Boris</style></author><author><style face="normal" font="default" size="100%">Magny, Michel</style></author><author><style face="normal" font="default" size="100%">Schmidt, Roland</style></author><author><style face="normal" font="default" size="100%">Bugmann, Harald</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Response of broadleaved evergreen Mediterranean forest vegetation to fire disturbance during the Holocene: insights from the peri-Adriatic region</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Biogeography</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Compositional change</style></keyword><keyword><style  face="normal" font="default" size="100%">cross-correlations</style></keyword><keyword><style  face="normal" font="default" size="100%">Fire history</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean vegetation</style></keyword><keyword><style  face="normal" font="default" size="100%">microscopic charcoal analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Pollen analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">redundancy analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">species diversity</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2009///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1111/j.1365-2699.2008.01987.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">36</style></volume><pages><style face="normal" font="default" size="100%">314 - 326</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Aim To test whether fire contributed to the expansion and compositional change of evergreen forests in the Mediterranean region during the Holocene. Location The peri-Adriatic region, encompassing the Italian peninsula, Sicily and the western and southern Balkans between latitudes 46° and 37° N. Methods New high-resolution pollen and microscopic charcoal data from Lago dell’Accesa (Tuscany, Italy) were used to estimate the response of the evergreen oak, Quercus ilex L., to fire during its expansion phase at 8500 cal. yr bp. The data were compared with the pollen and charcoal series from other Mediterranean sites (Lago di Massaciuccoli in Tuscany, Malo Jezero in Croatia, Biviere di Gela in Sicily) and analysed using numerical techniques (redundancy analysis, detrended canonical correspondence analysis) to identify long-term fire–vegetation linkages and the degree of compositional change. Results Microscopic charcoal and pollen of evergreen oaks were negatively correlated during the period of quasi-natural fire regime (Mesolithic, 10,000–8000 cal. yr bp). In addition, there was no such positive correlation during periods when the fire regime was potentially more influenced by people (Neolithic–Bronze Age, 8000–3000 cal. yr bp). Compared with inland sites, coastal sites that are currently located at a distinct ecotone showed more compositional change. Main conclusions The analyses suggest that climatic change, without an additional effect of fire regimes, favoured the expansion and compositional change of evergreen forests across the peri-Adriatic region. Strikingly different patterns occurred along a north–south gradient. In the north (Tuscany and Croatia, meso-Mediterranean belt), Q. ilex replaced deciduous forests when conditions became drier; in the south (Sicily, thermo-Mediterranean belt) the species replaced maquis or steppe vegetation when climatic conditions became moister. We conclude that the projected increase in fire activity may lead to the loss of most of the remaining relict forests of Q. ilex in southern Europe.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Blackwell Publishing Ltd</style></notes></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%">Vannière, B.</style></author><author><style face="normal" font="default" size="100%">Colombaroli, D.</style></author><author><style face="normal" font="default" size="100%">Chapron, E.</style></author><author><style face="normal" font="default" size="100%">Leroux, A.</style></author><author><style face="normal" font="default" size="100%">Tinner, W.</style></author><author><style face="normal" font="default" size="100%">Magny, M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Climate versus human-driven fire regimes in Mediterranean landscapes: the Holocene record of Lago dell’Accesa (Tuscany, Italy)</style></title><secondary-title><style face="normal" font="default" size="100%">Quaternary Science Reviews</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">CHARCOAL ANALYSIS</style></keyword><keyword><style  face="normal" font="default" size="100%">Climatic conditions</style></keyword><keyword><style  face="normal" font="default" size="100%">Fire regime</style></keyword><keyword><style  face="normal" font="default" size="100%">Holocene</style></keyword><keyword><style  face="normal" font="default" size="100%">human activities</style></keyword><keyword><style  face="normal" font="default" size="100%">Pollen analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Vegetation history (voyant)</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2008</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2008///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0277379108000620</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">27</style></volume><pages><style face="normal" font="default" size="100%">1181 - 1196</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">A high-resolution sedimentary charcoal record from Lago dell’Accesa in southern Tuscany reveals numerous changes in fire regime over the last 11.6kyr cal.BP and provides one of the longest gap-free series from Italy and the Mediterranean region. Charcoal analyses are coupled with gamma density measurements, organic-content analyses, and pollen counts to provide data about sedimentation and vegetation history. A comparison between fire frequency and lake-level reconstructions from the same site is used to address the centennial variability of fire regimes and its linkage to hydrological processes. Our data reveal strong relationships among climate, fire, vegetation, and land-use and attest to the paramount importance of fire in Mediterranean ecosystems. The mean fire interval (MFI) for the entire Holocene was estimated to be 150yr, with a minimum around 80yr and a maximum around 450yr. Between 11.6 and 3.6kyrcal.BP, up to eight high-frequency fire phases lasting 300–500yr generally occurred during shifts towards low lake-level stands (ca 11,300, 10,700, 9500, 8700, 7600, 6200, 5300, 3400, 1800 and 1350cal. yrBP). Therefore, we assume that most of these shifts were triggered by drier climatic conditions and especially a dry summer season that promoted ignition and biomass burning. At the beginning of the Holocene, high climate seasonality favoured fire expansion in this region, as inmany other ecosystems of the northern and southern hemispheres. Human impact affected fire regimes and especially fire frequencies since the Neolithic (ca 8000–4000cal.yrBP). Burning as a consequence of anthropogenic activities becamemore frequent after the onset of the Bronze Age (ca 3800–3600cal. yrBP) and appear to be synchronous with the development of settlements in the region, slash-and-burn agriculture, animal husbandry, and mineral exploitation. The anthropogenic phases with maximum fire activity corresponded to greater sensitivity of the vegetation and triggered significant changes in vegetational communities (e.g. temporal declines of Quercus ilex forests and expansion of shrublands and macchia). The link between fire and climate persisted during the mid- and late Holocene, when human impact on vegetation and the fire regime was high. This finding suggests that climatic conditions were important for fire occurrence even under strongly humanised ecosystem conditions.</style></abstract><issue><style face="normal" font="default" size="100%">11-12</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%">Carrión, J.

During the period ca 8390–6320 cal yr BP, Pinus dominated the pollen spectra, indicating a forested landscape over the high-elevation areas of the Sierra. From ca 6320–3800 cal yr BP, an expansion of deciduous oaks and other broad-leaf trees took place. After an optimum around 5800–5600 cal yr BP, mesophytes decreased in the 3800–2560 cal yr BP interval while a ﬁre-prone scrub became established. The main loss of forest accompanied the spread of thorny matorral after ca 2560 cal yr BP. Overall, this mountain region has shown itself to be sensitive to a range of inﬂuences, among which a continental climate that has become increasingly arid over the last 5000 years, the scarcity of soils suitable for cultivation, a geology that includes sources of copper and other metals and, especially, the incidence of grazing as well as the repeated appearance of ﬁres during the last 4000 years, are highlighted. The history of the vegetation of the Sierra de Baza seems clearly inﬂuenced by changes in local economy. Here we discuss how ecological transitions have interacted with cultural changes, with emphasis on the locally highly populated Chalcolithic (5700–4400 cal yr BP) and Argaric (4400–3550 cal yr BP) periods, as well as the Iberian period (3200–2220 cal yr BP). The sierra was abandoned during the Iberian Period which was, paradoxically, when the highest human impact on mountain vegetation is noticeable.</style></abstract><issue><style face="normal" font="default" size="100%">11-12</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%">Dorado, Miriam</style></author><author><style face="normal" font="default" size="100%">Rodr, Ana Valdeolmillos</style></author><author><style face="normal" font="default" size="100%">Zapata, M.

The obtained results have permitted the reconstruction of the climatic evolution in the area since the Late-glacial/Holocene transition. The end of the Late-glacial was characterized by a cold and arid climate and it concluded at about 98907180 yr BP. In the Early Holocene a slight climatic amelioration began, being interrupted by a more arid phase around 8500 yr BP. The Holocene Climatic Optimum started from ca. 8000 yr BP and was characterized by higher temperatures and more humidity. During the MidHolocene–Late Holocene times a stage of marked aridity occurred towards 5000 yr BP that preceded the development of a dry mediterranean climate. Under this new climate a short-time arid phase took place around 2500 yr BP after which the mediterranean conditions became accentuated, with an increasing dry climate. This climatic evolution has affected the characteristics of the marshlands of Las Tablas de Daimiel National Park, originating changes in the sedimentary environment. This environment was mainly ﬂuvial until the end of the Holocene Climatic Optimum and became lacustrine–palustrine from the beginning of the more arid conditions.</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%">Carrión, J.

Palaeoecological indicators include pollen, microcharcoal, spores of terrestrial plants, fungi, and non-siliceous algae, and other microfossils. The Siles sequence is shown to be sensitive to climatic change, although the control exerted by climate on vegetation is ultimately shaped by disturbances and species interactions, determining the occurrence of century-scale lags and threshold responses. Biotically induced changes of vegetation are also shown at the intrazonal level of variation. The new sequence is placed in the context of two previous records to postulate a picture of Holocene environmental change for the Segura region. The existence of mid-elevation glacial refugia for a number of temperate and Mediterranean trees is shown. A mid-Holocene phase (c. 7500– 5200 cal yr BP) emerges regionally as the time of maximum forest development and highest lake levels. The early Holocene occurs as a generally dry, pyrophytic period of pine forests, with grassland scrub in high altitudes, and the late Holocene as a period of protracted vegetation sensitivity, with return to development of pine forests, spread of xerophytic communities, and increased ﬁre activity, under the context of dry spells, localized anthropogenic disturbance, and shallowing and desiccation of lakes. Several events described here correlate with established times of abrupt transitions in the climates of northern Europe, the Mediterranean basin, north Africa, and the Sahel</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%">Beug, Hans-Jürgen</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">On the forest history of the Dalmatian coast</style></title><secondary-title><style face="normal" font="default" size="100%">Review of Palaeobotany and Palynology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Pollen analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Postglacial</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%">1967</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1967///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.sciencedirect.com/science/article/pii/003466676790156X</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">2</style></volume><pages><style face="normal" font="default" size="100%">271 - 279</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The Postglacial history of the vegetation of southern Dalmatia is studied by means of pollen analysis of the lake deposits of the Malo Jezero on the island Mljet.
