- Large scale and regional demographic responses to climatic changes in Europe during the final palaeolithicPublication . Schmidt, Isabell; Gehlen, Birgit; Winkler, Katja; Arrizabalaga, Alvaro; Arts, Nico; Bicho, Nuno; Crombé, Philippe; Eriksen, Berit Valentin; Grimm, Sonja B.; Kapustka, Katarina; Langlais, Mathieu; Mevel, Ludovic; Naudinot, Nicolas; Nerudová, Zdeňka; Niekus, Marcel; Peresani, Marco; Riede, Felix; Sauer, Florian; Schön, Werner; Sobkowiak-Tabaka, Iwona; Vandendriessche, Hans; Weber, Mara-Julia; Zander, Annabell; Zimmermann, Andreas; Maier, Andreas; Przemysław MroczekThe European Final Palaeolithic witnessed marked changes in almost all societal domains. Despite a rich body of evidence, our knowledge of human palaeodemographic processes and regional population dynamics still needs to be improved. In this study, we present regionally differentiated population estimates for the Greenland Interstadial 1d-a (GI-1d-a; 14-12.7 ka cal BP) and the Greenland Stadial 1 (GS-1; 12.7-11.6 ka cal BP) for Southern, Western, Northern and Central Europe. The data were obtained by applying the Cologne Protocol, a geostatistical approach for estimating prehistoric population size and density, to a newly compiled dataset of Final Palaeolithic sites. On a large spatio-temporal scale and compared to preceding Upper Palaeolithic phases, areas north of the Alps become the dominant demographic growth area for the first time since the dispersal of anatomically modern humans into Europe. At smaller scales, we observe divergent regional trends, with a conspicuous lack of archaeological evidence appearing in previously occupied areas of central France and Germany. Our study also shows that during the Final Palaeolithic, the climatic cooling of GS-1 coincides with a pronounced population decline in most parts of the study area. An apparent increase in population density occurs only in north-eastern Central Europe and north-eastern Italy. Our estimates suggest that the total population was reduced by half. Similar results, with a relationship between decreasing temperatures and decreasing populations, have already been observed for the late phase of the Gravettian, when populations were reduced to only one third of those estimated for the early phase. Yet, in contrast to the collapse of local populations during the late Gravettian, the increase in population densities in Central Europe during GS-1 indicates population movements eastwards, possibly in response to deteriorating climatic conditions, particularly in western regions during the Younger Dryas.
- Post-LGM environments and foragers on the move: New data from the lower Altmühl Valley (Franconian Jura, SE Germany)Publication . Barbieri, Alvise; Maier, Andreas; Lauer, Tobias; Mischka, Carsten; Hattermann, Merlin; Uthmeier, ThorstenAfter the Last Glacial Maximum, the Swabian and Franconian Jura (in SW and SE Germany, respectively) were repopulated by Magdalenian hunter-gatherers within the same communication network. However, while the Magdalenian settlement of the Swabian Jura dates to 17-14 ka cal BP, permanent Magdalenian occupations in the Franconian Jura date to 15-14 ka cal BP. In comparison with its western counterpart, the Franconian Jura was mostly excavated in the early days of archaeological research. Does this different chronology reflect the different history of research? Why did Magdalenian foragers establish permanent occupation in the Franconian Jura nearly 2 millennia after settling in Swabia, despite the fact these regions are only 150 km apart? To address these questions, we reinvestigated two sites in the Altmithl Valley with micromorphology and luminescence dating, namely Felsenhausl-Kellerhohle and Klausennische. Our data show that both sites have intact Pleistocene deposits. Among these, we identified sediments dating between 17 and 15 ka that show only rare lithic artifacts and microfeatures indicative of cold and arid conditions. Our work and published data suggest that the steady settlement of Magdalenian foragers in the Altmithl Valley starting 15 ka cal BP coincides with the end of this harsh period and the onset of cool and wetter environments. Data from the Swabian Jura demonstrated that in the Lone Valley, similar environments and Magdalenian occupations commenced earlier, starting 17 ka cal BR. Therefore, we propose that regional environments acted as a barrier against the dispersal of foragers in the Franconian Jura and determined its later Magdalenian occupation. Our research highlighted that different environments, taphonomic processes, and site uses probably coexisted across the German Jura. Therefore, it remains fundamental to expand the multisite data set proposed in this article to further test hypotheses about human/environment interaction in this region. (C) 2022 The Author(s).
