Data supporting: Isotopic insights on continental water sources and transport in the mountains and plains of southern South America
<p>The data presented here comprises the stable isotopic composition (δ<sup>2</sup>H and δ<sup>18</sup>O) of 1659 samples of precipitation, rivers, groundwater and lakes/ponds samples from a total of 511 sites. This is a composite dataset that includes data from the Global Network of Isotopes in Precipitation (GNIP) and Rivers (GNIR) databases (IAEA/WMO 2019), data extracted from different published articles (cited therein) and data obtained directly by the authors as part of different previous and ongoing projects of our own lab (GEA, IMASL). Excel sheet 1 shows a description/overview of the dataset as displayed in Table 1. Excel sheet 2 shows the dataset, which includes a unique identifying code, type of water sample (precipitation, rivers, groundwater, and lakes), name of location, sampling point date, latitude, longitude and elevation, and the dual isotopic composition (δ<sup>2</sup>H and δ<sup>18</sup>O).</p> <p>This dataset supports: Poca M, Nosetto MD, Ballesteros S, Castellanos G, Jobbágy EG. <em>Isotopic insights on continental water sources and transport in the mountains and plains of southern South America.</em> Isotopes in Environmental and Health Studies (IEHS). DOI:10.1080/10256016.2020.1819264</p> <p>We acknowledge all contributing researchers to GNIP and GNIR databases, as well as the effort of the IAEA for initiating and maintaining these open access global initiatives. We also acknowledge the authors of the papers cited in the dataset and all GEA lab staff that contributed to the sampling and/or to measuring the stable isotopic compositions of waters included in this database.</p> <p>This work was supported by Fondo para la Investigación Científica y Tecnológica under FONCyT-Grant BID PICT-2018-03143.</p> <p>For any query, please contact María Poca at: pocamaria@gmail.com</p>

Data from: Archaeological Central American maize genomes suggest ancient gene flow from South America
<p><span><span><span><span><span><span><span><span><span><span><span>Maize (<i>Zea mays</i> ssp. <i>mays</i>) domestication began in southwestern Mexico ~9,000 calendar years before present (cal. BP) and humans dispersed this important grain to South America by at least 7000 cal. BP as a partial domesticate. South America served as a secondary improvement center where the domestication syndrome became fixed and new lineages emerged in parallel with similar processes in Mesoamerica. Later, Indigenous cultivators carried a second major wave of maize southward from Mesoamerica, but it has been unclear until now whether the deeply divergent maize lineages underwent any subsequent gene flow between these regions. Here we report ancient maize genomes (2,300-1,900 cal. BP) from El Gigante rock-shelter, Honduras, that are closely related to ancient and modern maize from South America. Our findings suggest that the second wave of maize brought into South America hybridized with long-established landraces from the first wave, and that some of the resulting newly admixed lineages were then reintroduced to Central America. Direct radiocarbon dates and cob morphological data from the rock-shelter suggest that more productive maize varieties developed between 4,300 and 2,500 cal. BP. We hypothesize that the influx of maize from South America into Central America may have been an important source of genetic diversity as maize was becoming a staple grain in Central and Mesoamerica.</span></span></span></span></span></span></span></span></span></span></span></p>
Marine terraces of the last interglacial period along the Pacific coast of South America (1°N-40°S)
<p>This database comprises ~2,000 measurements of last interglacial marine terrace elevations along ~5,000 km of the western South American coast from northern Ecuador to south-central Chile (1°N-40°S). We used quantitatively replicable approaches constrained by previously published terrace-age estimates. Uncertainties were estimated on the basis of measurement errors and the distance from these referencing points.</p>
