Seasonal temperature and moisture changes in interior semi‐arid Spain from the last interglacial to the Late Holocene
The El Cañizar de Villarquemado pollen record covers the last part of MIS 6 to the Late Holocene. We use Tolerance-Weighted Averaging Partial Least Squares (TWA-PLS) to reconstruct mean temperature of the coldest month (MTCO) and growing degree days above 0°C (GDD 0 ) and the ratio of annual precipitation to annual potential evapotranspiration (MI), accounting for the ecophysiological effect of changing CO 2 on water-use efficiency. Rapid summer …
Humans take control of fire-driven diversity changes in Mediterranean Iberia’s vegetation during the mid–late Holocene
Fire regime changes are considered a major threat to future biodiversity in the Mediterranean Basin. Such predictions remain uncertain, given that fire regime changes and their ecological impacts occur over timescales that are too long for direct observation. Here we analyse centennial- and millennial-scale shifts in fire regimes and compositional turnover to track the consequences of fire regime shifts on Mediterranean vegetation diversity. We e…
Chironomid-inferred Holocene temperature reconstruction in Basa de la Mora Lake (Central Pyrenees)
We present the first Holocene chironomid-based summer temperature reconstruction for the Iberian Peninsula. A sequence from the shallow mountain lake Basa de la Mora (1914 m a.s.l., Central Pyrenees) was analysed and the reconstruction was performed by means of a merged Norwegian–Swiss chironomid calibration dataset. The presence of a multiproxy study conducted in the same lake, as well as other available regional temperature estimations, allowed…
Landscape, resources and people during the Mesolithic and Neolithic times in NE Iberia
Steppes, savannahs, forests and phytodiversity reservoirs during the Pleistocene in the Iberian Peninsula
Expected trends and surprises in the Lateglacial and Holocene vegetation history of the Iberian Peninsula and Balearic Islands
Patterns of human occupation during the early Holocene in the Central Ebro Basin (NE Spain) in response to the 8.2 ka climatic event
The Central Ebro River Basin (NE Spain) is the most northern area of truly semi-arid Mediterranean climate in Europe and prehistoric human occupation there has been strongly influenced by this extreme environmental condition. Modern climate conditions single out this region due to the harsh environment, characterised by the highest absolute summer temperatures of the Ebro River Basin. The Bajo Aragón region (SE Ebro River Basin) was intensively p…
Quaternary pollen analysis in the Iberian Peninsula
Most unsuccessful palynological work is never published. As a consequence, pollen analysts waste time re-processing sterile sediments, and the available literature exhibits a uniformly positive record of success in pollen extraction. Here we report failures with Quaternary pollen analyses in the Iberian Peninsula; that is, case studies where it was not possible to extract palynomorphs for pollen counting. Both totally sterile and partially steril…
A coastal reservoir of biodiversity for Upper Pleistocene human populations
Arid and humid phases in southern Spain during the last 4000 years
A multiproxy study of sediment cores from Zoñar Lake (37°29′00′′N, 4°41′22′′W, 300 m a.s.l.) supported by 11 14 C AMS dates provides the first high-resolution centennial-scale reconstruction of past humidity changes in southern Spain during the last 4000 years. Arid periods occurred prior to 2.9 cal. kyr BP and during 1.3—0.6 cal. kyr BP (`Mediaeval Climate Anomaly'). The most humid period occurred during 2.6—1.6 cal. kyr BP encompassing the late…
Climate variability in the Spanish Pyrenees during the last 30,000 yr revealed by the El Portalet sequence
Palynological, sedimentological and stable isotopic analyses of carbonates and organic matter performed on the El Portalet sequence (1802 m a.s.l., 42°48′00ʺN, 0°23′52ʺW) reflect the paleoclimatic evolution and vegetation history in the central-western Spanish Pyrenees over the last 30,000 yr, and provide a high-resolution record for the late glacial period. Our results confirm previous observations that deglaciation occurred earlier in the Pyren…
