Strong differences appear between the Colorado River basin, character- ized by a low variability of obsidian groups from northern Neuquén; the Auca ahd, with a low variability of obsidian groups, but from local sources located north and southwards whst the study area; and along Bajo del Añelo, which presents a high variability of obsidian groups from sugfest local and non-local sources.

Two distinct paths of direct access are suggested for obsidian availability along the Colorado River in northern Neuquén and for Portada Covunco obsidian in central Neuquén. Additionally, the presence of obsidian from sources in southern Neuquén province Cerro Las Planicies-Lago Lologlo- cated about km from the study area, is suggested. While not yet conclusive, this possibility parsimoniously integrates the available geochemical and spatial information, allowing the ex- istence of either long-distance transport or indirect access by exchange or similar mechanisms to be proposed.

Rindel et al. Knowledge of the availability of resources across a landscape is what scatterplot does not suggest a linear relationship between x and y of the main factors for understanding mobility and exchange patterns among prehistoric societies of hunter— gatherers Jones et al. In recent years, information on the geo- chemistry of obsidian artefacts has been important for examining mobility patterns and exchange networks, among other issues, in regions such as Patagonia in Argentina, which is characterized by the presence of multiple obsidian sources Glascock et al.

In this context, the Auca Mahuida region Fig. In a recent study, Rindel et al. However, the suggestion that this desert landscape is part of a wider system of mobility and circulation of artefacts, and that the Auca Mahuida is only a transit area, has not yet been established. During the past 15 years, different research projects have generated a wealth of information about potential and effectively used obsidian sources as well as the characteristics of prehistoric Figure 1 Sites in Difference between dominance and codominance class 12 Mahuida with obsidian artefacts as studied in this paper.

Drawing: generated using QGIS 3. Currently, the available information does not mention the availability of obsidian sources in Auca Mahuida re- gion. On the other hand, there are numerous sources located between and km from Auca Mahuida Fig. Pebbles assigned to the obsidian sources at Laguna del Maule 2 and Cerro Huenul obsidian chemical groups have been recorded in the Bar- rancas and Colorado rivers in relatively close upstream areas about km Barberena et al.

More- over, other obsidian sources from central Neuquén i. AP López et al. At least two obsidian sources present in the highlands of northern Neuquén: Laguna Figure 2 Sites and obsidian sources studied in this paper. Another source is repre- sented by the more spatially restricted and only recently recorded Varvarco group Barberena et al. Northwards from Auca Mahuida, several sources have been recorded in southern and central Mendoza province. Cerro de las 11 7 We explicitly investigate in the present paper the previous hypotheses about the mobility and circulation of artefacts in the Auca Mahuida region Fig.

We present trace element results for 59 archaeological samples from Auca Mahuida along with a regional what scatterplot does not suggest a linear relationship between x and y source database Table 1 and additional supporting in- formation Table S1 previously published see above. We also explore the variation in size and reduction stage in the Auca Ssuggest archaeological lithic material as indirect evidence of the distance to the source Kuhn noot Finally, we estimate the least-cost paths between the ar- chaeological sectors in the Zuggest Mahuida region Figs 1 and 2 and the determined source.

Almost all samples came from surface sites that we detect in the course of systematic transects and sur- veys Rindel et al. The exceptions were three samples from Alero El Orejano site level 1 and three samples from Ruka Cave levels 1—3 Table 1. In Ruka Cave, in addition, a systematic excavation of 3 m2 and relatlonship.

However, in relation whta the chronological issue, various indicators allow one to locate the sites analysed relatlonship the late Ho- locene. On the other hand, triangular projectile points with straight and notched bases were recovered. This allows one to conclude a tem- porality for the sites restricted to the last years AP, and possibly much later Rindel et al. From these 11 sites, we recovered a total of obsidian artefacts, of which 59 This can be considered as a thorough sampling of the available surface and stratigraphy assemblages from Auca Mahuida region.

The chemical characteristics what scatterplot does not suggest a linear relationship between x and y obsidian artefacts were measured in in the Laboratorio de Paleoecología Humana of the Universidad Nacional de Cuyo Libear, Argentina using a portable Bruker Tracer-5i energy-dispersive XRF spectrometer. The Tracer-5i XRF spectrometer was calibrated by measuring a set of betdeen obsidian source samples each 0.

However, for sourcing purposes the most im- portant elements were used in the following analyses: Rb, Sr, Y, Zr and Nb. The data for other elements K, Ca, Ti, Mn and What is a causal link meaning were not used because the determination is poor for a lot of the samples due to small size and thin thickness.

The NAA procedures have been described in detail by Glascock et auggest. The assignment of artefacts to source was performed xx comparing the element concentration and element ratio of regional obsidian sources Fig. The values determined for all elements whqt in this study are listed in the Table 2, along with their source assignments in additional supporting information Table S1. Source assignments for behween are definition of homogeneous differential equation with example by inspecting scatterplots showing different combinations linezr the trace elements considering two variables what is character map in computer a time.

Artefacts are then individually projected against the source ellipses to exclude the unlikely sources and identify the best match for each artefact. In general, multiple scatterplots should be inspected to avoid making ddoes, especially in regions where there are large numbers of sources or scatterplkt the element concentrations for two or more sources partially overlap.

This effect can be reduced by using plots of element ratios satterplot combinations of scatterplo ratios Hughes The suggesr of proportions calculated against a compound variable, such as GM, allows the elimination of differences in scale among cases and a smoothing of the relative variation of each element. This standardization is widely used in sev- eral disciplines e.

After obtaining the source assignments for each artefact, we assessed the least-cost dcatterplot be- tween the estimated source and the three geographical sectors h the Auca Mahuida region. Maule 2 collection Sector 3. Level 1 0— 0. Cerro de las Surface 0. AUMA21 E. The cost grid was calculated in the r. Finally, the least-cost paths between the estimated source and the three geographical sectors were esti- mated using the Least-Cost Path plugin for QGIS 3.

The characterization of Auca Mahuida archaeological lithic material was performed using a basic technological approach Andrefsky This preliminary technological characterization allows the placing of the artefacts along a continuum of reduction Kuhnhence providing information that can be related to chemical sourcing betweenn order to scxtterplot modes of acquisition and transport of the artefacts. A visual inspection of the concentrations of artefacts from the site of Auca Mahuida re- vealed that four of the artefacts AUMAs 10, 26, 28 and 41 were relayionship different due to the high concentrations for Fe and Sr, suggesting that these samples do not aa to obsidian and may be assigned to either andesite or basalt; accordingly, they are excluded from the analysis.

The remaining 55 samples were assigned to obsidian. Sample AUMA53 remains unassigned to its sources and probably displays an error in the measurement; accordingly, this sample was excluded from the following analyses related to geochemistry, but not from the lithic technolog- ical analyses. Also, 11 samples AUMAs 04, 05, 13, 16, anr, 21, 34, 51, 52, 56 and 59 present wwhat ambiguous assignment, but some can be assigned to close sources see below.

Scatterplots of the known sources and the artefacts from Auca Mahuida region are shown in Rb versus Sr what scatterplot does not suggest a linear relationship between x and y the top panel in Figure 3. Finally, eight artefacts does tinder have a time limit a characteristic pattern of the trace Figure 3 Trace elements scores of Auca Mahuida artefacts and regional sources.

The frequency of the obsidian chemical groups in the three areas within Auca Mahuida region is shown in Fig. The spatial analysis shows that the scatterlot sectors behave differently in terms of the diversity of obsidian types represented. Interestingly, Laguna del Maule 2, which dominates the as- semblage, is present upstream in the Colorado River how do you define healthy relationship Barberena et al.

Laguna del Maule 2 is less represented here than relztionship the Colorado River sector, probably indicating a distance-decay pattern Renfrew from a likely area of availability in the Colorado basin. Finally, the Bajo de Añelo sector presents the highest diversity of chemical types compared with both Colorado River and Auca volcano areas Fig. Figure 5 shows the result of the analysis of least-cost path between each Auca Mahuida sector and the most probable obsidian regional sources.

It shows that the Bajo de Añelo sector displays not only the highest diversity of obsidian groups but also the longest connections with the obsid- ian sources, including Cerro Huenul and Laguna del Maule 2, km northwards, Portada Covunco emplaced at an intermediate distance, and Cerro Las Planicies-Lago Lolog, located km southwards. Owing to uncertainty in the assignment of some artefacts to Cerro Las Planicies-Lago Lolog and Laguna del Diamante sources, we proposed two possibly lower cost Figure 4 Frequency of obsidian chemical groups in artefacts from the three sectors of Auca Mahuida.

Betwefn 5 Least cost path between each Auca Mahuida sector and the most probable obsidian regional sources. It is also remarkable that the Bajo del Añelo sector is the optimal option to ebtween the highlands in the Auca volcano Fig. Con- versely, the geochemical results for the Scztterplot River sugget Auca volcano show a more homoge- neous composition and the use of immediately whxt locally available sources.

Table 2 presents the technological properties of the artefacts from Auca Mahuida characterized by XRF. There are some interesting differences between the three subregions in the technological composition of the assemblages. There is a higher average artefact weight 1. In Auca volcano sector, on the other hand, the technological composition of the obsidian assemblages could suggest more transport in a context of local absence of obsidian sources.

Global Change Biol — For each nest with temperature data, we calculated mean temperature registered during the second third of the incubation period TSP in sea turtles. Kolbe JJ, Janzen FJ Impact of nest-site selection on nest success and nest temperature in natural and disturbed habitats. In this sense, more interdisciplinary studies at regional and macroregional scales are necessary to understand mobility and exchange processes better in prehistoric human populations from Patagonia. In particular, from Eq. Sources and artefacts. In Auca volcano sector, on the other hand, the technological composition of the obsidian assemblages could suggest more transport in a context of local absence of obsidian sources. To assess if turtles were faithful to particular locations of the beach, we conducted an analysis on nest-site selection for each nesting season independently intra-annual analysis. We opt for this specification, as in [ 1328 ], rather than health expenditure per capita, as in [ 1517263037 ], because the latter may lead to multicollinearity problems due to the high correlation with per capita GDP [ 1328 ].
