[ES] Knowledge of the climatic and environmental changes of the start of Holocene and its impact on human populations and cultures is key to understanding both the predictive and future evolution of these. In this regard, the study using ditches and surveys of the holocene archaeosedimentary register in the area of the neolithic deposit of Los Cascajos (Los Arcos, Navarre) provides valuable information not only for establishing the environmental development of this area, but also for knowledge of the activities carried out by the residents of the deposit on the banks of the river Odrón. This work presents the results of the stratigraphic, sedimentological and geochemical study using high resolution XRF-CS of the LAC1 sounding. The data obtained indicate a trend towards aridification throughout the Holocene, represented by a cycle of agradation-incision in the river Odrón. The river sedimentary register also detects indicators of contemporary anthropic activity in the settlement of Los Cascgars, which makes it possible to place its occupation at hydrological times more humid than the current one, and to demonstrate the subsequent aridification of this area of the Ebro valley along the recent Holocene (Megalayense).

Stable carbon and nitrogen isotope research on past populations in the Iberian Neolithic has emphasized the Atlantic and Mediterranean coasts. This study provides the first isotopic insights into the diet and subsistence economy of Early and Middle Neolithic populations from open-air sites in interior north-central Iberia. We present bone collagen carbon (?13C) and nitrogen (?15N) isotope ratios for 44 humans and 33 animals recovered from six cemeteries of the Ebro valley and the northern Iberian Plateau. The results obtained are consistent with the C3 terrestrial diets typical of other contemporary south-western European populations, but the spacing between human and herbivore values from Los Cascajos and Paternanbidea sites is higher than expected, and a significant positive correlation is identified between the ?13C and ?15N human values at both. Moreover, the results clearly differ from those of the Late Neolithic/Early Chalcolithic in the same region, which show significantly lower ?13C and ?15N values. These findings contribute to an understanding of the implementation of an agro-pastoral economy in interior Iberia, suggesting a stronger reliance on animal foods among the first Neolithic groups of inner Iberia than in subsequent periods as well as differential access to some resources (possibly suckling herbivores) in the diet, which may point to the existence of early social or economic inequalities that do not seem to be linked to age and sex parameters or to mortuary treatment. ; This research was funded by the Basque Government (POS_2013_1_147; POS_2014_2_24; POS_2015_2_ 0001) and the Spanish Ministry of Economy and Competitiveness (project 'Coastal societies in a changing world: A diachronic and comparative approach to the Prehistory of SWEurope from the late Palaeolithic to the Neolithic (CoChange)' (HAR2014-51830-P)). The study has also been supported by a Newton International Fellowship funded by the British Academy (NF170854); the Basque Government (IT542/10); the University of the Basque Country (UPV/EHU) (UFI11/09); and the Spanish Ministry of Science and Innovation (projects 'Los Caminos del Neolítico' (HAR2009-09027) and 'Los Caminos del Neolítico II' (HAR2013-46800-P)).

This paper presents the results of the first excavation campaign of the Artusia rock shelter in Unzué, Navarre, Spain. Chronocultural and archaeobiological analyses revealed five different occupation phases (Artusia I–V) within the regional Mesolithic timeline, specifically in the Mesolithic of Notches and Denticulates (Artusia I and II) and the Geometric Mesolithic (Artusia III, IV, and V). In addition, the study of the sedimentological and palaeoenvironmental evolution in the entire record helped to clearly define several climatic events which developed around 6550 cal BC–8500 cal BP and 6250 cal BC–8200 cal BP. Here, we present a description of these events and their (pre)historical interpretation with the aim of recognizing how they influenced the Mesolithic hunter–gatherer groups living in the Ebro Basin of the Iberian Peninsula. ; projects "Los Caminos del Neolítico" -HAR2009- 09027- and "Los Caminos del Neolítico II" -(HAR2013-46800-P)- under directed by Dr. Manuel Rojo Guerra, granted by the Subdirectorate General for Research Projects/General Directorate of Research and Management of the National Plan for R and D and Innovation/Secretary of State for Research of the Ministry of Science and Innovation of Spain, and co-financed by the Government of Navarre.
