However palaeoecology of fire is still poorly understood, especially at high-altitude mountain environments, despite the fact that these are fire-sensitive ecosystems and their resilience might be affected by changing fire regimes. We reconstruct wildfire occurrence since the Lateglacial (14.7calka BP) to the Mid-Holocene (6calka BP) and investigate the climate–fuel–fire relationships in a sedimentary sequence located at the treeline in the Central Spanish Pyrenees. Pollen, macro- and micro-charcoal were analysed for the identification of fire events (FE) in order to detect vegetation post-fire response and to define biomass–fire interactions. mean fire intervals (mfi) reduced since the Lateglacial, peaking at 9–7.7calka BP while from 7.7 to 6calka BP no fire is recorded. We hypothesise that Early Holocene maximum summer insolation, as climate forcing, and mesophyte forest expansion, as a fuel-creating factor, were responsible for accelerating fire occurrence in the Central Pyrenees treeline. We also found that fire had long-lasting negative effects on most of the treeline plant communities and that forest contraction from 7.7calka BP is likely linked to the ecosystem's threshold response to high fire frequencies.</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, José S.</style></author><author><style face="normal" font="default" size="100%">Fernández, Santiago</style></author><author><style face="normal" font="default" size="100%">González-Sampériz, Penélope</style></author><author><style face="normal" font="default" size="100%">Gil-Romera, Graciela</style></author><author><style face="normal" font="default" size="100%">Badal, Ernestina</style></author><author><style face="normal" font="default" size="100%">Carrión-Marco, Yolanda</style></author><author><style face="normal" font="default" size="100%">López-Merino, Lourdes</style></author><author><style face="normal" font="default" size="100%">López-Sáez, José a</style></author><author><style face="normal" font="default" size="100%">Fierro, Elena</style></author><author><style face="normal" font="default" size="100%">Burjachs, Francesc</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Expected trends and surprises in the Lateglacial and Holocene vegetation history of the Iberian Peninsula and Balearic Islands</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%">Holocene</style></keyword><keyword><style  face="normal" font="default" size="100%">iberia</style></keyword><keyword><style  face="normal" font="default" size="100%">palaeobotany</style></keyword><keyword><style  face="normal" font="default" size="100%">palaeoecology</style></keyword><keyword><style  face="normal" font="default" size="100%">palaeogeography</style></keyword><keyword><style  face="normal" font="default" size="100%">quaternary</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/S0034666710000023</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">162</style></volume><pages><style face="normal" font="default" size="100%">458 - 475</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Recent, high-resolution palaeoecological records are changing the traditional picture of post-glacial vegetation succession in the Iberian Peninsula. In addition to the inﬂuence of Lateglacial and Early Holocene climatic changes, other factors are critical in the course of vegetation development and we observe strong regional differences. The ﬂoristic composition, location and structure of glacial tree populations and communities may have been primary causes of vegetation development. Refugial populations in the Baetic cordilleras would have been a source, but not the only one, for the early Lateglacial oak expansions. From Mid to Late Holocene, inertial, resilient, and rapid responses of vegetation to climatic change are described, and regional differences in the response are stressed. The role of ﬁre, pastoralism, agriculture, and other anthropogenic disturbances (such as mining), during the Copper, Bronze, Iberian, and Roman times, is analysed. The implications of ecological transitions in cultural changes, especially when they occur as societal collapses, are discussed.</style></abstract><issue><style face="normal" font="default" size="100%">3</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></records></xml>
