The palaeoecoloical potential of pollen records in caves: the case of Mediterranean Spain

subject

description

Abstract Important palynological sequences are reviewed from caves with archaeological interest in Mediterranean Spain. Upper Pleistocene sites include Abric Romani and Abric de l’Arbreda in NE Spain, and in SE Spain Cueva de la Carihuela, Cova Beneito, Cueva de Perneras, Cueva del Algarrobo and the Holocene Cova de l’Or and Cova de les Cendres. Carihuela has the longest sequence, starting in the last interglacial and covering most of the last glaciation. A pre-Wurm phase was followed by two glacial maxima separated by an interpleniglacial phase, and in the Lateglacial the Younger Dryas seems present. Whereas at Carihuela harsh pleniglacial conditions caused Mediterranean associations to disappear, in the milder surroundings of Beneito and Perneras these were able to survive. At Romani, pollen shows acute palaeoclimatic sensitivity, pointing to upland refuges nearby. Holocene pollen from Cova de l’Or and Cendres underlines the importance of pine in natural woodlands of mature meso and thermomediterranean taxa. Some between-site comparisons and contrasts with modern bioclimatology are interpreted in the context of the palaeoclimate history. Despite taphonomical and methodological problems of cave palynology, its future in arid regions such as SE Spain is promising.
