The lake is located in the coastal infra-Mediterranean vegetation belt at 2 m a.s.l. Pollen, charcoal and sedimentological analyses are used to explore linkages among vegetation, fire and climate at a decadal scale over the past 1200 years. A dry period from ad 800 to 1000 that corresponds to the Medieval Warm Period' (WMP) is inferred from sedimentological analysis. The high content of carbonate recorded in this period suggests a dry phase, when the ratio of evaporation/precipitation was high. During this period the island was dominated by thermophilous and drought-tolerant taxa, such as Quercus ilex, Olea, Pistacia and Juniperus. A marked shift in the sediment properties is recorded at ad 1000, when carbonate content became very low suggesting wetter conditions until ad 1850-1900. Broadly, this period coincides with the Little Ice Age' (LIA), which was characterized by wetter and colder conditions in Europe. During this time rather mesic conifers (i.e. Pinus pinaster), shrubs and herbs (e.g. Erica arborea and Selaginella denticulata) expanded, whereas more drought-adapted species (e.g. Q. ilex) declined. Charcoal data suggest enhanced fire activity during the LIA probably as a consequence of anthropogenic burning and/or more flammable fuel (e.g. resinous Pinus biomass). The last century was characterized by a shift to high carbonate content, indicating a change towards drier conditions, and re-expansion of Q. ilex and Olea. The post-LIA warming is in agreement with historical documents and meteorological time series. Vegetation dynamics were co-determined by agricultural activities on the island. Anthropogenic indicators (e.g. Cerealia-type, Sporormiella) reveal the importance of crops and grazing on the island. Our pollen data suggest that extensive logging caused the local extinction of deciduous Quercus pubescens around ad1750.</style></abstract><issue><style face="normal" font="default" size="100%">10</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND&lt;br/&gt;publisher: SAGE PUBLICATIONS 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%">Fernández, Santiago</style></author><author><style face="normal" font="default" size="100%">Fuentes, Noemí</style></author><author><style face="normal" font="default" size="100%">Carrión, José S.</style></author><author><style face="normal" font="default" size="100%">González-Sampériz, Penélope</style></author><author><style face="normal" font="default" size="100%">Montoya, Encarna</style></author><author><style face="normal" font="default" size="100%">Gil, Graciela</style></author><author><style face="normal" font="default" size="100%">Vega-Toscano, Gerardo</style></author><author><style face="normal" font="default" size="100%">Riquelme, José a</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The Holocene and Upper Pleistocene pollen sequence of Carihuela Cave, southern Spain</style></title><secondary-title><style face="normal" font="default" size="100%">Geobios</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">historical biogeography</style></keyword><keyword><style  face="normal" font="default" size="100%">Holocene</style></keyword><keyword><style  face="normal" font="default" size="100%">palaeoecology</style></keyword><keyword><style  face="normal" font="default" size="100%">Spain</style></keyword><keyword><style  face="normal" font="default" size="100%">Upper Pleistocene</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetation history</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2007///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0016699506001033</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">40</style></volume><pages><style face="normal" font="default" size="100%">75 - 90</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">A new pollen sequence (ca. 15,700–1250 yr BP) is presented for three stratigraphical sections of Carihuela Cave (Granada, southeastern Spain), thus completing a record that covers from the last Interglacial to late Holocene.

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%">Jahns, Susanne</style></author><author><style face="normal" font="default" size="100%">Bogaard, Christel</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">New palynological and tephrostratigraphical investigations of two salt lagoons on the island of Mljet, south Dalmatia, Croatia</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%">Climatic impact</style></keyword><keyword><style  face="normal" font="default" size="100%">human impact</style></keyword><keyword><style  face="normal" font="default" size="100%">Mercato-Ottaviano tephra</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetation history</style></keyword><keyword><style  face="normal" font="default" size="100%">Vesuvius</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1998</style></year></dates><publisher><style face="normal" font="default" size="100%">Springer-Verlag</style></publisher><volume><style face="normal" font="default" size="100%">7</style></volume><pages><style face="normal" font="default" size="100%">219-234</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In the sediments of both of the investigated lakes, the tephra from the Mercato-Ottaviano eruption (Vesuvius, southern Italy) (ca. 7900 B.P.) could be identified. The palynological investigations show that from ca. 9000-7200 B.P. (8000-6000 cal B.C.) deciduous oak forests predominated, with only a few representatives of Mediterranean vegetation. At the transition to the central European Atlantic Period those forests changed to an open vegetation type, dominated byJuniperus andPhillyrea. At about 5500 B.P. (4400 cal B.C.), theJuniperus-Phillyrea vegetation was replaced byQuercus ilex woodland that still occurs on the island of Mljet today and is considered to be the natural vegetation of the Dalmatian coastland. The associated vegetation of theQ. ilex forests changed several times. At the beginning of theQ. ilex period,Juniperus values were still high, but soon they decreased andErica spread. In more recent times theQ. ilex forests were partially replaced by plantations ofPinus halcpensis. Indicators of human impact are sparse throughout the pollen record. Clear evidence for human influence exists only from ca. 3100 B.P. (1300 cal B.C.) whenJuglans andPinus halepensis were introduced to the area. Later,Olea andSecale cultivation can be suggested and further spreading ofJuniperus indicates use of the land as pasture.</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%">RAMIL-REGO, P</style></author><author><style face="normal" font="default" size="100%">RODRÍGUEZ-GUITIÁN, M</style></author><author><style face="normal" font="default" size="100%">MUÑOZ-SOBRINO, C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Sclerophyllous vegetation dynamics in the north of the Iberian peninsula during the last 16,000 years</style></title><secondary-title><style face="normal" font="default" size="100%">Global Ecology and Biogeography</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Holocene</style></keyword><keyword><style  face="normal" font="default" size="100%">iberian peninsula</style></keyword><keyword><style  face="normal" font="default" size="100%">Late-glacial</style></keyword><keyword><style  face="normal" font="default" size="100%">palynology</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">sclerophyllous forests</style></keyword><keyword><style  face="normal" font="default" size="100%">species range</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetation history</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1998</style></year></dates><publisher><style face="normal" font="default" size="100%">Blackwell Science Ltd</style></publisher><volume><style face="normal" font="default" size="100%">7</style></volume><pages><style face="normal" font="default" size="100%">335-351</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We used pollen analysis to evaluate the dynamics of sclerophyllous arboreal taxa during the last 16,000 years.

During the Late-glacial and the Holocene, sclerophyllous elements became widespread in many areas of the north Iberian peninsula (the Sil, Duero and Ebro depressions and the southernmost slopes of adjacent mountains), with the smallest pollinic representation of these taxa being for the most septentrional areas (coastal/sub-coastal territories and the northermost slopes of the Cantabrian-Atlantic Mountains). During these periods, there is no indication of the presence of Quercus ilex pollen in the northwestern territories, which would explain the absence of this species in the present-day landscape. Despite the widespread distribution that sclerophyllous elements have maintained during the last 16,000 years, they have never attained a predominant role in the landscape, having a smaller representation, both during hotter and colder phases, than deciduous forests, pine forests and mixed forests.</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%">Watts, W A</style></author><author><style face="normal" font="default" size="100%">Allen, J R M</style></author><author><style face="normal" font="default" size="100%">Huntley, B</style></author><author><style face="normal" font="default" size="100%">Fritz, S C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Vegetation history and climate of the last 15,000 years at Laghi di Monticchio, southern 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%">climate reconstruction</style></keyword><keyword><style  face="normal" font="default" size="100%">FOREST</style></keyword><keyword><style  face="normal" font="default" size="100%">Holocene (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">Pollen analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetation history</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1996</style></year></dates><volume><style face="normal" font="default" size="100%">15</style></volume><pages><style face="normal" font="default" size="100%">113-132</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In southern It;aly, vegetation contemporary with the end of the last glacial maximum, from 15,000 to 12,000 years ago, is shown by pollen-analysis to have been treeless and steppe-like in character.

High percentages of lUia point to a rich mesic forest that was contemporary with the ‘Allerod’ intersta- dial of northern Europe. A major decline in mesic trees with an accompanying return of Beth and steppe genera dated to 10,500 years ago identifies a ‘Younger Dryns’ climatic reversal. Betula and steppe genera were replaced by forest of Quercus and other mesic trees, notably Ulmus (elm), as the Holocene began. In the later Holocene, ca. 4000 years ago, Abies (fir), Curpinus betulus (hom- beam) and Taxus (yew) appeared. Abies and Tuxus became extinct locally about 2500 years ago, either because of climatic change, or perhaps because of the effects of early agriculture. The Full- glacial climate is thought to have been cold and summer-dry with mainly winter precipitation. The Lateglacial ‘Boiling-Allereld’ Interstadial was summer-wet and warm. The response-surface based climate reconstruction indi’zates an early Holocene climate with markedly colder winter conditions than today, about -5°C compared with 3.9-C today as a mean temperature for the coldest month. The annual temperature sum is reconstructed as somewhat higher than today, 3500 degree days as compared with a calculated value of 2900 for today. The later Holocene had a climate like today’s, Rainfall, and variation in iis seasonal distribution, has been a critical determinant of the vegetation cover. The fossil pollen record at Laghi Di Monticchio has been complemented by diatom and plant macrofossil studies which provide evidence of former lake environments as well as data on the upland forest. Lake levels remained high during the Full- and Lateglacial with encroachment of shore vegetation during th,e Holocene. The sediments also have an exceptionally rich record of tephra falls which are of importance in dating and core correlation. Twenty-one macroscopically visible tephras occur in sediments of the last 15,000 years</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%">MORA, M T R</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">CONTRIBUTION OF CHARCOAL ANALYSIS TO THE STUDY OF VEGETAL PALEOENVIRONMENT IN CATALONIA (SPAIN)</style></title><secondary-title><style face="normal" font="default" size="100%">BULLETIN DE LA SOCIETE BOTANIQUE DE FRANCE-ACTUALITES BOTANIQUES</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%">REGIONAL PATERNS</style></keyword><keyword><style  face="normal" font="default" size="100%">vegetation history</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1992</style></year></dates><publisher><style face="normal" font="default" size="100%">SOC BOTANIQUE FRANCE</style></publisher><pub-location><style face="normal" font="default" size="100%">RUE J B CLEMENT, 92296 CHATENAY-MALABRY CEDEX, FRANCE</style></pub-location><volume><style face="normal" font="default" size="100%">139</style></volume><pages><style face="normal" font="default" size="100%">483-493</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Charcoal analysis of seventeen archaeological sites in Catalonia (north-east of Spain) gives an approach to the Holocenic vegetation history for this area. We establish four regionals patterns for the vegetation evolution : interior non continental, north-mediterranean, south-mediterranean and interior continental. We also notice the effects of anthropic action and the ancient distribution of particular species : Olea europeae, Fagus sylvatica, Pinus halepensis, Quercus suber.</style></abstract></record></records></xml>
