Significance It has long been assumed that climate played a major role in the population history of Central Andes. Although adaptations Andean populations to climatic changes such as intensification agriculture have inferred from archaeological record, evidence for demographic migration is missing so far. In this paper, ancient DNA data lived southern Peru between 840 BC and 1450 AD provide two large-scale migrations Andes coincident with episodes drought increased variability. These led...
Abstract. High-altitude peatlands of the Andes still remain relatively unexploited although they offer an excellent opportunity for well-dated palaeoenvironmental records. To improve knowledge about climatic and environmental changes in western southern Peru, we present a high-resolution record Cerro Llamoca peatland last 8600 years. The 10.5 m long core consists peat intercalated sediment layers was examined all kinds microfossils. We chose homogeneous sections pollen analysis at decadal to...
The paper presents proxies from an interdisciplinary geoarchaeological working group. Sediment analyses and geomorphological studies, radiocarbon ages of snail shells luminescence dating loess allow a preliminary chronology the environmental evolution eastern Atacama desert, Nazca–Palpa region (southern Peru). Until now, typical desert was unknown arid western flank Andes points to periods more humid conditions with open grasslands at margin in early middle Holocene. In footzone Andes,...
Abstract. This integrated pedo-geoarchaeological study focuses on three abandoned pre-Hispanic terrace agricultural systems near Laramate in the southern Andes of Peru (14.5° S), aiming to unravel pedological and land-use history region, which served as a significant hub during times. The key objectives investigation involved contextualizing former management system within its geomorphological palaeoecological framework assessing impact practices soil development quality by comparing...
The southern Peruvian coastal desert around Palpa, Peru (14.5°S) is currently characterized by hyper-arid conditions. However, the presence of two species molluscs ( Scutalus , Pupoides ) and desert-loess deposits indicates past development semi-desert grassland ecosystems caused a displacement eastern margin due to hydrological changes. Radiocarbon dating shows that transition semi-arid climate in took place during Greenland interstadial 1, ∼ 13.5 cal ka BP. At beginning Holocene, mollusc...
Abstract Oxygen isotope records of cushion‐plant peat cellulose from the southern central Andes capture evidence for significant environmental changes. We observe that δ 18 O cell peatland record Cerro Tuzgle (24°S) is in high conformity with respective Lagunillas (27°S). During late Holocene, two fluctuations occurred and are interpreted as regional moisture signals increased precipitation amounts indicated during multi‐centennial phases 1,530 to 1,270 cal. yr BP 470 70 BP. These can be...
ABSTRACT A Late Holocene paleoenvironmental record was obtained from the Lagunillas cushion peatland (LP, 27°12′S, 69°17′W), located in dry Puna of western Central Andes. Ten radiocarbon dates build chronology for last 1800 cal a BP. Analyses stable isotopes on cellulose (δ 18 O cell , δ 13 C ) and geochemical proxies organic matter OM 15 N bulk TOC, TN, LOI, T 535 were conducted to identify major changes this record. Simultaneously, ambient water O, 2 H) plant samples dominant species...
Abstract. Within palaeoenvironmental studies, high-altitude peatlands of the Andes still remain relatively unexploited, although they offer an excellent opportunity for high-resolution chronologies, on account their high accumulation rates and abundant carbon dating. Especially in central Andes, additional high-quality proxy records are needed due to lack continuous well-dated records, which show a significant variability sub-centennial decadal precision scales. To widen current knowledge...
Abstract. This integrated pedo-geoarchaeological study focuses on three abandoned prehispanic terrace agricultural systems near Laramate in the southern Andes of Peru, aiming to unravel pedological and land-use history region. The investigation involved contextualizing former management system within its paleoecological framework assessing impact practices soil development quality. complex, with diverse varied geomorphological settings, provided an ideal setting for investigation....
Abstract. Intensive human intervention in the natural drainage system of Hessische Ried (Upper Rhine Graben, Germany) resulted transformation a large wetland into an intensively used cultural landscape. At least since first century CE, when Romans conducted early river regulation and water management, network has experienced extensive anthropogenic re-organisation. The LandGraben project focuses on reconstruction watercourse systems along Landgraben, tributary to northern Ried. Several...
