“…Finally, different regional studies used time series analyses of summed probability distributions of calibrated radiocarbon dates (SPD) to discuss the impact of the 8.2k cal a BP climatic event on Iberian Mesolithic populations (Bernabeu et al, 2014 andMontes et al, 2016;Fyfe et al, 2019;Alday et al, 2018;Fernández-López de Pablo et al, 2019;McLaughlin et al, 2021;Clark and Barton 2022). These studies reported very different results: from studies identifying positive trends in demographic growth such in the Iberian Atlantic areas of Central Portugal (McLaughlin et al, 2021) and Asturias-Cantabria (Clark and Barton 2022), to others that do not identify a clear impact as in the Mediterranean area (Fyfe 2019) and the Ebro valley (Clark and Barton 2022;Alday et al, 2018), or those that, at subregional level, have identified both positive and negative trends (Fernández-López de Pablo et al, 2019;Bernabeu et al, 2016;Montes et al, 2016).…”
