Socio-ecological adaptation to Early-Holocene sea-level rise in the western Mediterranean

摘要: Abstract Consecutively to the global sea-level rise, coastal landscapes significantly changed during Early Holocene. We explored how mutations have affected ancient human systems in western Mediterranean. The Pego-Oliva basin (Spain) provides a thick sediment sequence located proximity two well-studied Mesolithic and Neolithic archaeological sites. Based on 16 cores, sedimentological analyses, 14C dates, integration of previous works, we reconstructed architecture sedimentary facies chronology deposition for last 9500 years. From 9500 8200 cal. BP, stepwise inland migration coastline is characterised by peat layers at distinct depths indicating four phases barrier-lagoon development. marine transgression caused disappearance lagoon reached maximum position 7300 cal. BP. Since 5800 cal. stabilisation induced progradation system construction. Five flooding dated 9500, 9100–9000, 8750–8650, 8450–8200, 8100–7300 cal. BP match Atlantic meltwater pulses. Comparison archaeology shows that long-lasting occupation corresponds presence offering easily exploitable local intertidal resources. In contrast, Late Mesolithic, observe contraction reduction bivalves size arguing decrease resource productivity. This changes ecosystems negatively impacted populations leading less intense this area. Therefore, 700 years' temporal hiatus between hunter-gatherers first farmers occupying area explained formerly exploited biotopes because situation may been aggravated coincidence climate event. maximal sea corresponded shift from infralittoral species Impressa/Precardial Postcardial Neolithic, good adaptation changing environments time. However, comparison suggests communities with different cultural baggage had perception same environment. By past perspective, it emphasises ecosystem value as benefit or constraint, risks associated relies regional scales adaptive capacity society changes.
