“…Many studies have demonstrated that vegetation responded differently during the beginning of the Holocene through the Iberian Peninsula, depending on their location relative to the Atlantic -Mediterranean gradient. More temperate and moister conditions were inferred from the Atlantic-influenced pollen sites (Muñoz Sobrino et al, 2005Moreno et al, 2011;Iriarte-Chiapusso et al, 2016) where a rapid spread of deciduous forest occurred, while continental and Mediterranean sequences show high proportions of pines and/or junipers (Carrión et al, 2010;Rubiales et al, 2010;Morales-Molino et al, 2013;Aranbarri et al, 2014Aranbarri et al, , 2015, indicating still intense hydrological stress due to maximum seasonality during the Early Holocene.…”

“…In the Alavese region, there is no master palaeoenvironmental sequence spanning the entire Late Pleistocene/Holocene period, and those available are obtained from caves and rockshelters without high-resolution analyses. In any case, relatively close regional sequences show that the vegetation landscape during the Late glacial (prior to 12900 cal BP) was defined by the progressive substitution of conifers by Betula-deciduous Quercus-Corylus communities, as recorded in Eurosiberian pollen profiles both from the Pyrenees (Gil-Romera et al, 2014;González-Sampériz et al, 2006) and the Cantabrian sector (Iriarte-Chiapusso et al, 2016;Moreno et al, 2011). The GS-1 represents a clear biostratigraphic marker in this region, shaping a treeless landscape with low lake levels (Moreno et al, 2011) and glacier readvances (García-Ruiz et al, 2016).…”

The Ebro Basin constitutes one of the most representative territories in SW Europe for the study of prehistoric societies during the Pleistocene-Holocene transition. The correlation of palaeoenvironmental and geomorphological proxies obtained from sedimentary records with chronologically well-constrained reference archaeological sites has allowed defining this time frame precisely, such that three main pilot areas haven been broadly depicted: the Alavese region, the Pre-Pyrenees and the Bajo Aragón. Overall, the human imprint in the Ebro Basin was rare during the Upper Palaeolithic, but more visible from the Upper Magdalenian (14500 to 13500 cal BP) to Neolithic times (up to 5500 cal BP). Local environmental resources were continuously managed by the prehistoric communities in the different areas of study. In fact, the Ebro Basin acted during those millennia as a whole, developing the same cultural trends, industrial techniques and settlement patterns in parallel throughout the territory. However, some gaps exist in the 14 C frequency curve (SCDPD curve). This is partially related to prehistoric sites in particular lithologies and geological structures that could have partly been lost by erosional processes, especially during the Early Holocene. In addition, this gap also parallels the reconstructed climate trend for the Pre-Pyrenean and the Bajo Aragón areas, which are defined by high frequencies of xerophilous flora until ca. 9500 cal BP, suggesting that continental climate features could have hampered the presence of well-established human communities in inland regions. The interdisciplinary research (archaeology, geomorphology and palaeoclimatology) discussed in this paper offers clues to understand the existence of fills and gaps in the archaeological record of the Ebro Basin, and can be applied in other territories with similar geographic and climate patterns.

“…The current Atlantic population, which is located in the protected coastal valleys of southern Galicia and probably in the contiguous north of Portugal until Porto, experienced one of the most optimal climatic conditions for a chestnut refuge during the LGM (Benito-Garzón et al, 2007;Roces-Díaz et al, 2018). Germplasm of this deme is currently present also in inland south Galicia (data not reported), a region where regular presence of Castanea pollen was identified during Late Glacial and Early Holocene (Iriarte-Chiapusso et al, 2016). The oldest pollen records in this area are 71 and 100 ka in Porto (Ribeiro et al, 2014(Ribeiro et al, , 2019.…”

The demographic history of Castanea sativa Mill. in southwest Europe: A natural population structure modified by translocations

In domesticated species, translocation of materials can alter natural demographic patterns; this may have occurred in Castanea sativa (European chestnut), a species conserved in several refuges, with a long domestication history for nut production. Bayesian analysis of population genetic structure in marginal areas and in the centre of C. sativa range, considering spatial information and making corrections for unbalanced size, allowed visualization of a genetic structure that was subsequently analysed by approximate Bayesian computation to assess its natural demographic history and test the origin of some hypothetical translocated germplasm. We obtained evidence of C. sativa population contraction during the earliest Pleistocene, resulting in a split into eastern (Greek) and western (Italian and Iberian) populations. The northern Iberian population, in the Eurosiberian area, is one of the vestiges that remained after the contraction that split the global Tertiary population. A secondary encounter, occurred from Middle to Upper Pleistocene, which explains the hybrid origin of the Western Mediterranean population present in Italy and in the centre and south of the Iberian Peninsula. It has been demonstrated that a germplasm translocation from Italy to the Central Iberian Range may have occurred. Recent translocations have hybridized with the local northern Iberian population, producing naturalized populations with high diversity. The populations of C. sativa in southwestern Europe have a genetic structure compatible with a natural origin, in which signs of population contractions and expansions caused by climatic oscillations since the Late Miocene have been imprinted.
