“…The chronostratigraphical setting of the selected pollen sites is mainly based on magnetostratigraphical data (Bertini, 2000;Leroy, 2008;Madurell-Malapeira et al, 2010;Corrado and Magri, 2011) and on radiometric dates of tephra layers (Ablin, 1991;Karner et al, 1999;Munno et al, 2001;Nomade et al, 2010). In a number of cases the chronology of the pollen records is not well constrained, being based on a combination of lithostratigraphical and mammalian fauna information (Lona and Ricciardi, 1961;Julia Bruguès and Suc, 1980;Leroy, 1997;Magri et al, 2010;Russo Ermolli et al, 2010).…”

“…Nevertheless, slightly later during the Early-Middle Pleistocene transition, a decrease in the diversity of plant species is recorded in northeastern Iberia and southern France (Magri and Palombo, 2013, Fig. 2; Pastre et al, 2007;Julià and Suc, 1980;Albin, 1991).…”

The Pleistocene of the Iberian Peninsula is currently a focus of intense paleontological, archaeological and geological research. To a large extent, these inquiries are intended to decipher the ecological factors that might have conditioned early Homo dispersals into the European continent during the late Early Pleistocene. In this respect, the research carried out during the last twenty years in several areas of the Iberian Peninsula (the Guadix-Baza Basin, the Sierra de Atapuerca, the Vallparadís Section and the Banyoles-Besalú Basin) have yielded a large amount of new significant data. Here we review such data and provide for the first time a comprehensive synthesis from a faunal, geological and paleoecological perspectives, by focusing on the relationship between paleoenvironmental conditions and early human dispersals during the late Early Pleistocene in the Iberian Peninsula. In particular, the Iberian fossil record of Early to Late Villafranchian large mammals is synthesized, on the basis of recent publications and unpublished data collected by the authors during the last five years, in order to provide the adequate faunal and paleocological framework for understanding the factors that limited or conditioned human dispersal events.Keywords: Mammals, Pliocene, Pleistocene, Villafranchian, Iberian Peninsula Resumen El Pleistoceno de la Península Ibérica es actualmente foco de intensa investigación paleontológica, arqueológica y geológica. En gran medida, estos trabajos están encaminados a descifrar los factores ecológicos que podrían haber condicionado las dispersiones de los Homo iniciales hacia Europa durante el Pleistoceno inferior. En este sentido, la investigación realizada durante los últimos veinte años en diversas zonas de la Península Ibérica (la Cuenca de Guadix-Baza, la Sierra de Atapuerca, la Sección de Vallparadís y la Cuenca de BanyolesBesalú) ha proporcionado una gran cantidad de nuevos datos significativos. Aquí revisamos estos datos y se proporciona por primera vez una síntesis exhaustiva desde una perspectiva paleontológica, paleoecológica y geológica, centrándonos en las relaciones entre las condiciones paleoambientales y las dispersiones de los primeros humanos en el Pleistoceno inferior de la Península Ibérica. Concretamente, se sintetiza el registro fósil ibérico de grandes mamíferos villafranquienses en base a publicaciones recientes y datos inéditos recopilados por los autores en los últimos cinco años, para así proporcionar el marco faunístico y paleoecológico adecuado para comprender los factores que limitaron o condicionaron los eventos de dispersión humana.

“…Thanks to this unrivalled effort, 74 taxa have been indicated for the first time in the Mediterranean Late Cenozoic (table 2). Any pollen analyst wishing to develop a robust botanical approach can find a complete documentation on fossil and modern pollen descriptions and photographs in the theses mentioned in table 1 and following papers (Lobreau-Callen & Suc, 1972;Suc, 1973Suc, , 1974Suc, , 1976aSuc, , 1976bSuc, , 1978aSuc, , 1978bNaud & Suc, 1975;Julià Bruguès & Suc, 1980;Cravatte & Suc, 1981;Bessedik, 1983;Suc et al, 1986;Bessais & Cravatte, 1988;Zheng, 1990;Suc et al, 2004;Popescu et al, 2010;Biltekin et al, 2015). For building synthetic pollen diagrams, taxa are mostly grouped according to a global "ecological niche" corresponding to the mean annual temperature (MAT) under which their present-day representatives are living (Nix, 1982) plus other climatic (mainly linked to xericity) or edaphic considerations, and their status that can be deduced from variations in their pollen records over time (table 2): -Megatherm plants inhabiting equatorial and tropical forests: MAT>24°C; -Mega-mesotherm plants living in subtropical forests: 24°C>MAT>20°C; -Mesotherm plants corresponding to warmtemperate forests: 20°C>MAT>14°C; -Meso-microtherm plants growing in cooltemperate forests, including Cathaya, a relictuous altitudinal conifer in subtropical China: 14°C>MAT>12°C; -Microtherm plants constituting the boreal coniferous forests: MAT<12°C; present-day pollen records and plant distribution (Fauquette et al, 1998a(Fauquette et al, & b, 2007.…”

Subtropical evergreen forests left room for Mediterranean sclerophyllous communities, and finally to Artemisia steppes which alternated with mesophilous forests during glacial-interglacial cycles. The South Mediterranean plant ecosystems contrasted with open subdesertic associations where Avicennia persisted up to the early Pliocene before the steppes invaded the lowlands. Neogene climate changes benefited the Mediterranean sclerophyllous plants that were already present in the early Miocene. Their subsequent fluctuations relate not only to temperature variations but maybe also to phases with high instability in seasonality and low variability in warmth. When present, Microtropis fallax is a serious candidate for identifying the primary Mediterranean sclerophyllous assemblages. Interpretation and climate quantification of the pollen data show a well-marked latitudinal contrast in the Mediterranean area both in temperature and humidity/dryness. The thermic latitudinal gradient is characterized
