The cooling and drying associated with the so-called ‘8.2 ka event’ have long been hypothesized as having sweeping implications for human societies in the Early Holocene, including some of the last Mesolithic hunter-gatherers in Atlantic Europe. Nevertheless, detailed ‘on-site’ records with which the impacts of broader climate changes on human-relevant environments can be explored have been lacking. Here, we reconstruct sea surface temperatures (SST) from δ18O values measured on subfossil topshells Phorcus lineatus exploited by the Mesolithic human groups that lived at El Mazo cave (N Spain) between 9 and 7.4 ka. Bayesian modelling of 65 radiocarbon dates, in combination with this δ18O data, provide a high-resolution seasonal record of SST, revealing that colder SST during the 8.2 ka event led to changes in the availability of different shellfish species. Intensification in the exploitation of molluscs by humans indicates demographic growth in these Atlantic coastal settings which acted as refugia during this cold event.

The knowledge about the evolution of the mountain areas is a very interesting issue from the palaeoenvironmental stand point, but also from the archaeological view in relation with human occupations. In this paper we analyze the composition and evolution of the vegetation of the peat bog of Sotombo, located in the vicinity of the Collados del Asón Natural Park (Cantabria) over the last 6000 years, through the study of pollens, spores and non-pollen palynomorphs, with the support of 8 AMS radiocarbon dates. The main results point the dominance of deciduous forests with pines between ca. 5926-2418 cal BP. From this moment is clearly evident the anthropogenic activities, in contemporary to the expansion of the beech forests. Subsequently (from ca. 596 cal BP) starts the development of mountain meadows, that dominate the current landscape.

ResumenEn este trabajo se presenta el análisis palinológico de un perfil estratigráfico del yacimiento arqueológico de Torreparedones, situado en la campiña de Córdoba, con una cronología comprendida entre el IV y el I milenios cal. BC. En él se documenta un proceso de creciente degradación del encinar, que se iniciaría durante el Calcolítico mediante el desarrollo de actividades agrícolas y ganaderas, que se haría aún más manifiesto durante el Bronce Final y la Época Ibérica, dentro de un proceso de aridificación generalizado. Se plantea la relación del abandono del yacimiento durante el III milenio cal. BC respecto al evento climático abrupto 4200 cal. BP.Palabras clave: Edad del Cobre; Bronce Fina; Palinología; Paleoambiente; Cambio climático; Córdoba. AbstractIn this work we present the palynological study of a stratigraphic profile from Torreparedones archaeological site, located in the countryside of Córdoba, with a chronology between the IV and I millennia cal. BC. A 36Cuaternario y Geomorfología (2015), 29 (3-4), process of increasing degradation of evergreen oak woodland, which would begin during the Chalcolithic by developing farming activities, is documented. This would become even more evident during the Late Bronze and the Iberian Epoch within the widespread aridity. The relationship of the abandonment of the site during the III millennium cal. BC respect to the 4200 cal. BP abrupt climate event is proposed.

En el siguiente artículo se analiza la novela de Fernanda Kubbs La puerta entreabierta poniendo el foco principalmente en la nueva versión de la figura del autómata, que cuenta con diversos precursores a lo largo de la historia de la literatura y la cultura. No obstante, la versión renovada del autómata que propone la escritora presenta unas características particulares que lo alejan parcialmente de la tradición literaria en la que se inserta. Se podría afirmar que se trata de un pretexto para introducir en la obra un conjunto de referencias intertextuales y culturales que recuerdan a algunos de sus predecesores más relevantes (como Frankenstein o el ajedrecista de Wolfgang von Kempelen) con una finalidad estética, es decir, para crear una atmósfera narrativa con ecos históricos que inviten al lector a reconocerlos a modo de juego.
