In order to characterize long-term individual diets, we present δ13C and δ15N data from osteological remains of the caviomorph rodents Dolichotis patagonum, Myocastor coypus, Lagostomus maximus, Lagidium viscacia, Microcavia australis, Galea leucoblephara and Ctenomys sp., recovered from archaeological and recent contexts. These data are analyzed by temporal and geographic context and compared with the previous dietary studies based on macrorremains and microhistological analysis. Significative differences were found between rodents from Monte and Patagonian phytogeographic provinces, as well as between archaeological and modern members of the genus Ctenomys, indicating diet changes between Late Holocene and recent times individuals, that could confirm the climatic variations and/or the recent overgrazing effect. The results indicate trends in rodent diets of 20th and 21st centuries were different to those of the Late Holocene, suggesting a decrease in precipitation and/or an increase of the summer pattern of the same, and/or an increase of mean annual temperature. In addition, this work confirms the generalist strategy of several taxa, although mainly in Ctenomys, which its diet co-varies with these environments.

procedentes del campo volcánico de La Payunia (sur de Mendoza, Argentina). Estudios previos
en el centro oeste argentino y Chile central abordaron desde una escala macro regional, el rol las fuentes
de obsidiana dentro de las redes de interacción y movilidad humana en diferentes escalas temporales. En
La Payunia se identificaron dos fuentes de obsidiana, ubicadas en áreas con características ambientales
e historia ocupacional diferentes: fuente El Peceño en área el Nevado y fuente Payún Matrú en área El
Payén. Se explora desde escalas meso y micro espaciales, y sobre la base de estudios tecnológicos de
artefactos caracterizados por medio de fluorescencia de rayos-X (XRF), las estrategias de abastecimiento
y posibles rangos de acción humana en el extremo sur de Mendoza, durante la segunda mitad del Holoceno
tardío. Los resultados sugieren marcadas diferencias en el modo uso estas fuentes, así como en la
amplitud y direccionalidad de los territorios explotados.

Materials found and analyzed include lithics, ceramics, archaeobotanical, zooarchaeological and human remains. The paper attempts to adjust the state of knowledge of the pre-Hispanic agricultural dispersal using new information. Two discontinuous temporal pulses were recorded in La Olla, the former around 1900 years 14C BP and the later between 700 and 400 years 14C BP. The archaeological analysis confirms stability in human subsistence and human diet based on low rank resources which included carob (mesquite) and small animals such as fish and armadillo. Changes in the technological organization were also recorded, which are interpreted in terms of mobility and action ranges. The archaeological record of La Olla site shows a different perspective about the human occupation to the classic contexts of Atuel II and Atuel I sites.

ethnohistorical information that illustrates the importance of fish exploitation in the Guanacache lagoons during historical times. However, –with a few exceptions– the zooarchaeological
record has been poorly explored in relation to this issue, even though a large number of fish remains are found on different areas of the plains. this work deals with the data obtained from
fish remains recovered at Altos de Melien II, sector I (Guanacache) and compares them with those from other archaeological assemblages recovered from nearby contexts. It aims to improve our knowledge about fish consumption in this area of north-eastern Mendoza, with special attention to potential formation processes involved in this kind of assemblages. the ichthyoarchaeological record from AM II is dominated by the creole perch (Percichthys trucha), even though from specimens the patagonian pejerrey (Odontesthes hatcheri) have been also identified. Body part representation and other indicators have been analysed. It is suggested that
the assemblage reflects primarily the waste products of subsistence exploitation.

But the lack of multi-decadal records represents an important gap in information that hinders the development of the research agenda. Without improved information on the long-term and complex interactions between causal factors and responses, it will be difficult to answer key questions about trends, rates of
change, tipping points, safe operating spaces and pre-impact conditions. Where available long term monitored records are too short or lacking, palaeoenvironmental sciences may provide continuous multi-decadal records for an array of ecosystem states, processes and services.
Combining these records with conventional sources of historical information from instrumental monitoring records, official statistics and enumerations, remote sensing, archival documents, cartography and archaeology produces an evolutionary framework for reconstructing integrated
regional histories. We demonstrate the integrated approach with published case studies from Australia, China, Europe and North America.

in the Andes Cordillera), which makes it both difficult to access under ideal conditions and inaccessible for much of the year. Prehistoric use of the Las Cargas source can inform us about mobility, subsistence choices, economics of stone consumption, trade, and territoriality. Here we present the results of
various lines of evidence (surface survey, X-ray fluorescence and instrumental neutron activation analyses, artifact morphometry, and obsidian hydration dating) used to characterize obsidian from Las Cargas and its prehistoric use
during the Holocene. Results indicate that Las Cargas obsidian occurs at the source as blocks and nodules, which are chemically homogeneous and of variable quality. Use of the source was nearly continuous through time, and the primary knapping activities performed there were the production of blanks and preparation of cores.

America is a topic mostly addressed in historical written documents with little use
of the archaeological record and bioarchaeological or culture material. To counteract
this weakness, this paper presents a study of the diet in individuals living in
central-western Argentina between the seventeenth, eighteenth, and nineteenth
centuries. The paper, focusing on historical bioarchaeology using stable isotopes
(δ13C, δ15N, δ18O) from bone samples of human skeletal remains found in
Mendoza, Argentina. The aim is to reconstruct the human diet and its residential
mobility. Our results show little inclusion of maize in these populations’ diets,
significantly less than those for the same region during pre-Hispanic times. The
data do not indicate a historic continuity in dietary practices between pre-Hispanic
and post Hispanic human population.

As a result of this analysis and of regional systematic surveys we identified four new obsidian sources. A total of 70 artifacts from 20 archaeological sites dating to different moments of the Holocene were assigned to seven distinct sources, with changes in procurement and distribution through time. Results are discussed in the context of some of the regional mobility models proposed by several scholars.

The goal of this analysis is to establish bases from which to interpret regional trends in the distribution of the archaeological record that connect these areas, which have been traditionally considered to be geographically decoupled. We propose a standardized methodology for selecting ages that provide a reliable human signature. Variations in date frequencies in a regional scale are discussed with the use of summed probability distributions. Radiocarbon voids at the regional level previously identified in Midwest Argentina are explored. Regional chronological information is compared to the available paleoenvironmental records, thereby emphasizing the possible role of climate pulses in the spatial organization of human populations. Significant arid conditions between 7800 and 5700 cal BP are coincidental with a focused occupation of the Andes Mountains, area which may have offered stable resources; thus more effectively occupied when compared to other environmental bands.
Keywords: radiocarbon dates; climate change; human paleoecology; hunter-gatherers; mid-Holocene; Subtropical Andes.

Llancanelo lagoon, a saline lake and wetland located between the Monte and Patagonian deserts of
Mendoza, Argentina. We collect stable C, N, and O isotope data from human remains from the eastern
and northern margins of Llancanelo and compare them with C and N data from an array of local plants
and animals, zooarchaeological data from local archaeological sites, and C, N, and O data from human
remains elsewhere in southern Mendoza. The isotopes and archaeofaunas from Llancanelo show a low
reliance on guanaco and rheids and a moderate reliance on aquatic resources and small, terrestrial game.
Although there are no corresponding archaeological remains, the isotope data also suggest a heavy use of
mesquite (Prosopis ssp.) and Hardee peppertree (Schinus polygamus). Carbon and nitrogen isotope data
from the human remains reveal no significant differences between samples from the Llancanelo area and
human remains from the rest of Mendoza. When analized by subarea, however, humans from the west
of the lake are more similar to individuals from La Payunia and the eastern plains and humans from the
south of Llancanelo more similar to individuals from the Andean piedmont. Based on this information
we suggest that Llancanelo acted as a point of population convergence and was exploited in a fashion
complementary to other areas in the south of Mendoza.

These has been stimulated the discussion about both the real meaning of the non local goods presence in the region and the time when these became more frequent in the archaeological record. However, until now the information available about the kind and place of recovered materials has been not systematized, as a result this has finished in the present dispersion of the discussion. These discussion had been focused on particular sites or materials. The present paper all the archaeological information available from the region is presented and it will be discussed within the different exchanges archaeological and ethnographic models.

are presented from an area located in the lower Gualcamayo River Basin (in the northwestern part of the Province of San Juan), which includes sites with surface and sub-surface material, as well as burials from a period between 2300 and 1100 bp. Using these results, ideas for the development or expansion of agropastoral practices in northwest San Juan are discussed. Based on this, arguments are presented in favor of the possibility that there was an expansion of agropastoral groups from the northeastern valleys after 2100 bp. It is also argued that these societies did not incorporate maize as an
important resource in their diets during at least 1000 years.

Archaeological evidence dating earlier than 8 kya suggests that hunter-gatherers were highly mobile with hunting oriented lithic technology and lacking milling equipment, but acquired a broad spectrum of faunal prey and tended to camp near wetland environments. Debate about the adaptive implications of these traits often devolves to whether they are best characterized as Paleo-Indian, Paleoarchaic, or Prearchaic in comparison to subsequent Archaic (broad-spectrum foraging) adaptations. At the transition from Early to Middle Holocene, the Great Basin witnessed higher effective temperatures and reduced aquatic resource zones. Most archaeologists agree that the proliferation of milling equipment marks inception of the Archaic, but the relative importance of terrestrial fauna and aquatic resources, and the effects of climatic aridity on human occupation and mobility remain unclear (Grayson 2011).

Here we develop an environmental frame of reference (Binford 2001) to model regional Late Pleistocene through Middle Holocene subsistence and mobility based on climatic variables inferred from paleoenvironmental proxies. Our goal is to develop expectations about the range of hunter-gatherer adaptations feasible under climatic scenarios posed for the Late Pleistocene and Early-to Middle Holocene Great Basin.We proceed in four steps: 1) extrapolate a geographic grid from a global climatic model to capture climatic variability across the Great Basin and compare with weather station records to assess how well the model captures current climate; 2) alter monthly precipitation and temperature to reflect climatic parameters of Bølling-Allerød, Younger Dryas, Early Holocene, and Middle Holocene climatic scenarios, and assess their accuracy against independent paleoenvironmental proxies; 3) predict hunter- gatherer subsistence and mobility under the current climate model and compare to 38 hunter-gatherers groups falling within the Great Basin using the Environmental Calculations program [ENVCALC2.1] (Binford and Johnson. 2014); and 4) generate expectations about hunter-gatherer subsistence and mobility under each of the four paleoclimatic models.
