[EN]: A new pollen sequence (c. 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 Lateglacial is characterized by open landscapes with junipers and early colonisation of Quercus, while the Holocene is depicted by mixed oak forests, with a diversity of broad-leaf trees and scrub, which decrease after c. 5470 yr BP synchronously with the expansion of xerophytes and occurrence of indicators of anthropogenic disturbance. The whole pollen record of Carihuela fits into the general trends described for reference pollen sites of southern Europe, including Padul in the province of Granada, and other sequences from Mediterranean Spain, through which the heterogeneity of environmental change increases from Middle to Late Holocene. We conclude that, differently to other regions of Spain, deciduous Quercus-dominated forests are very old in eastern Andalusia, thus conflicting with floristic phytosociological models of vegetation change that contend the potentiality of monospecific Q. Ilex / rotundifolia woodlands in the region
[ES]: Se presenta una secuencia de polen (c. 15.700-1.250 BP) para tres niveles estratigráficos de la Cueva de Carihuela (Granada), que completan un registro que cubre desde el Último Interglacial hasta finales del Holoceno. El Último Glacial se caracteriza por paisajes abiertos con sabinas y colonias tempranas de Quercus, mientras que el Holoceno está descrito por bosques de Quercus mixtos, con una diversidad de árboles de hoja anchas y matorrales que disminuyen después de c. 5470 BP, a la vez que se expanden las xerofitas y aparecen indicadores antropogénicos. Todo el registro de polen de Carihuela encaja en la tendencia general descrita por otros lugares de referencia de pólenes en el sur de Europa, incluyendo Padúl (Granada), y otras secuencias de la España mediterránea. De manera diferente a otras regiones de España, los bosques dominados por Quercus caducifolios en Andalucía oriental son muy antiguos, y están en conflicto con modelos fitosociológicos florísticos de cambios de vegetación, que contienen la potencialidad de los bosques mono-específicos Q. ilex / rotundifolia de la región.
