“…These were progressively replaced by mixed mesophytic forests, and finally by deciduous broad‐leaved forests during the Late Miocene (Kovar‐Eder, 2003). This high‐latitude cooling was accompanied by lower‐latitude drying and the development of open landscapes in Mediterranean regions, such as the inner Iberian basins (Rivas‐Carballo, 1991) and Turkey (Strömberg et al. , 2007).…”

Aim To analyse the diversity dynamics of Miocene mammalian faunas in the Iberian Peninsula in order to determine whether the patterns are related to the dispersal of taxa from other areas into this region.Location Mainly the Iberian Peninsula, but two close geographical areas (Central Europe and the Eastern Mediterranean) are also considered in some of our calculations.Methods Genus-level faunal lists for a total of 299 localities from the Iberian Peninsula, covering 10 successive biochronological units [Mammal Neogene (MN) zones] that span from the latest Early Miocene to the early Pliocene (about 17-4 Ma), were compiled. The dataset was expanded with a further 331 localities in Central Europe and the Eastern Mediterranean for the same time span. Next, a taxonomically standardized database was used to create composite faunal lists of micro-and macromammalian genera present during each MN zone. Separate genera-by-MN-zone matrices for both micro-and macromammals were built for each region. Mean standing diversity as well as origination and extinction rates were calculated for the Iberian Peninsula, and their correlation with preservation rates is discussed. Simpson's coefficient of faunal similarity with Central Europe and the Eastern Mediterranean was calculated in order to evaluate whether diversity patterns were related to changes in the affinity of the Iberian mammalian faunas with those of other regions.Results Diversity changes in the Iberian macromammalian faunas coincide with periods of increased faunal similarity with other regions, suggesting a relationship to the expansions and contractions of the geographical ranges of the constituent taxa. This pattern is not recognized for micromammals; that is, their diversity trends are not related to changes in geographical ranges.Main conclusions Climatic shifts result in expansions or contractions in the geographical ranges of macromammals, owing to changes in the distribution of their preferred habitats. The lower dispersal ability of micromammals results in a higher extinction risk when habitat fragmentation confines their populations to relatively small environmental patches. Hence, they are more severely affected by climatic changes. Our results thus emphasize the role of climatic forcing in mammalian biogeography and diversity.

“…Around 8.5 Ma there was an extremely dry phase during which rain was almost absent in the centre of the Iberian Peninsula. The first signs of these conditions appear in the Middle Miocene record, but they became generalized in the Duero Basin during the Vallesian (Lower Tortonian) (Valle & Salvador de Luna, 1985a,b; Rivas Carballo & Valle, 1987; Rivas Carballo, 1991a,b; Rivas Carballo et al. , 1994; Valle et al.…”

AimThe aim of this work was to identify the main changes in the flora and vegetation of the Iberian Peninsula over the Cenozoic Era, to record the disappearance of taxa associated with these changes and to determine the influence of climate and human activity on these events. LocationThe Iberian Peninsula and Balearic Islands.Methods A critical review was made of the palaeobotanical literature with the aims of detecting patterns of floristic change and extracting information on the disappearance of different taxa over the Cenozoic. These data are viewed alongside the most recent data for the climate of this period. A critical analysis is made of the role of Palaeotropical and Arctotertiary taxa in the forest communities of the Iberian Peninsula throughout the Cenozoic.Results Although the Eocene-Oligocene transition was a time when many taxa disappeared, the most outstanding events occurred between the end of the Oligocene and throughout the Miocene. Substantial floristic changes took place over this period, including the disappearance of 177 Palaeotropical taxa. This was probably related to acute cooling and aridification; no evidence exists that the Messinian Salinity Crisis had any important effect in the Iberian Peninsula. The last great disappearance of Palaeotropical taxa (36 in total) ended in the MiddleLate Piacenzian; Arctotertiary taxa were most affected during the Pleistocene. The Lower-Middle Pleistocene transition, best represented by marine isotopic stages (MIS) 36-34 and 20-18 and characterized by a change in glacial cyclicity, was the time of the last notable disappearance of taxa. Main conclusionsThis work provides the first chronogram of extinctions for the Iberian flora, and records the disappearance of 277 taxa during the Cenozoic. A clear relationship was detected between the main climatic events and the latest appearances of the different taxa.

“…These ecosystems existed in the northeastern, central and southern regions and were characterized by Asteraceae and Amaranthaceae (Valle-Hernández et al, 2006;Barrón et al, 2010a). In the central sector of the Duero Basin (Provinces of Palencia and Valladolid), open landscapes existed and steppe vegetation with Asteraceae, Amaranthaceae, Poaceae and Plantaginaceae grew during the Vallesian (Rivas-Carballo, 1991;Rivas-Carballo et al, 1994). The Cupressaceae were of some importance, probably due to the continental conditions that reigned.…”
