- Rapid climatic events and long term cultural change: the case of the Portuguese Upper PaleolithicPublication . Bicho, Nuno Gonçalo Viana Pereira Ferreira; Cascalheira, João; Marreiros, Joao; Pereira, TelmoIn Western Europe, the Upper Paleolithic is marked by clear regional and diachronic technological differences. Some of these are most likely related with human adaptations to the Late Pleistocene environmental shifts. In this paper we focus on the rapid climatic change events and their influence on the Iberian regional ecology and vegetation cover. Based on those changes and their impact on the main Upper Paleolithic cultural phases in central and southern Portugal, we propose an explanatory model, to be tested in the future, where rapid climatic events, such as the D-O and Heinrich Events, have direct impact on the ecology and vegetation cover and this, in turn, cause changes in human adaptations in terms of mobility, settlement patterns, land use and technology.

- Lithic technological adaptation within the Gravettian of the Iberian Atlantic region: results from two case studiesPublication . Bradtmoller, Marcel; Marreiros, Joao; Pereira, Telmo; Bicho, NunoThe origins and expansion of Gravettian industries in Western Europe have recently been considered a cultural mosaic phenomena marked by regional technological facies. Probably associated with climatic oscillations, the development of these facies is likely related to sociocultural patterns and human adaptations to different ecological niches. Thereby, changes of subsistence strategies and mobility patterns are also reflected by technological and typological adaptations and innovations within the lithic assemblages. With the Iberian Peninsula being an important ecological niche for studying these phenomena, we conducted a comparative analysis of two occupations to test human ecological and lithic technological adaptations during the early Gravettian in Iberia: Cueto de la Mina on the northern Iberian Atlantic coast and Vale Boi on the western Portuguese Atlantic coast. Results show that these occupations exhibit major technological differences, but also strong similarities in the case of typological innovation/adaptation, possibly related to local resource accessibility (e.g. high-quality raw material). Based on these observations, the study provides further information concerning possible connections throughout the Iberian Atlantic coastline during an early Gravettian timeframe.
