Economic directness is a new model of socioeconomic organization for the Paracas culture (800–200 BC) in southern Peru, with wider implications for economic theory of the prehispanic Andean past. Using an archaeoeconomic approach to analyze settlement patterns, obsidian artifacts, malacological material, and camelid skeletal remains, this study rec...

There are many unanswered questions about the population history of the Central and South Central Andes, particularly regarding the impact of large-scale societies, such as the Moche, Wari, Tiwanaku, and Inca. We assembled genome-wide data on 89 individuals dating from ∼9,000-500 years ago (BP), with a particular focus on the period of the rise and...

This article contributes to the debate on the habitat of "New World" camelids in pre-Colonial South America and provides new insights into the breeding and herding strategies developed by Andean societies. The case discussed here refers to the Late Paracas period (370 to 200 BCE) in the Palpa valleys of the western Andes in south Peru. Tooth enamel...

In recent decades, habitat change and the intensive management of wild ungulates for hunting have led to an increase in their populations in south-central Spain. This implies a higher generation of hunting waste, which can favour the transmission of infectious diseases, including tuberculosis (TB). The aim of this study was to assess the usefulness...

West Nile virus (WNV), Usutu virus (USUV) and tick‐borne encephalitis virus (TBEV) are emerging zoonotic flaviviruses (family Flaviviridae), which have circulated in Europe in the past decade. A cross‐sectional study was conducted to assess exposure to these antigenically related flaviviruses in eastern grey squirrels (Sciurus carolinensis) in Ital...
Chapter
Archaeological research in the Palpa valleys, southern coast of Peru, has revealed the existence of a long cultural process, during which the site of Pernil Alto had an important role in the process of settlement in the Palpa valleys during the Mid-Archaic Period (3600–3000 BC) and the Initial Period (1500–800 BC). In this paper, we present the pre...

En el presente artículo se exponen los resultados de las excavaciones realizadas en varias estruc­turas asociadas a sitios con geoglifos, los cuales se localizan en la parte norte de la cuenca del Río Grande, en la provincia de Palpa, departamento de lea. Los geoglifos fueron construidos sobre las laderas y mesetas que se encuentran entre y a lo la...
Chapter
The Palpa valleys and its tributaries, in the coastal and highlands of southern Peru, are being investigated by a multidisciplinary team of archaeologists and geographers from Peru and Germany, aiming to reconstruct the region’s cultural processes in terms of a varied landscape and changing climate. Research has revealed a long cultural process tha...

The L-band Synthetic Aperture Radar (SAR) data were collected by the NASA UAVSAR platform almost exactly two years apart, on 19 March 2013 and on 21 March 2015. The second of the two flights was conducted to see if the production of a very high-resolu- tion decorrelation image (described below) could detect and gauge the degree of any disturbance t...

In this paper we report on our use of Synthetic Aperture Radar (SAR) as a means of monitoring the Lines and Geoglyphs of Nasca and Pampas de Jumana World Heritage Site in Peru, where the colossal ground drawings, popularly known as the Nasca Lines, are found. Our research to date indicates that the environment in which the Nasca geoglyphs are found...
Chapter
This edited volume focuses on the funerary archaeology of the Pan-Andean area in the pre-Hispanic period. The contributors examine the treatment of the dead and provide an understanding of how these ancient groups coped with mortality, as well as the ways in which they strove to overcome the effects of death. The contributors also present previousl...

‘Paracas ’ is the term used to describe one of the most important cultures of the Central Andean area, originally discovered by Tello, Mejía Xesspe and associates at various sites of the Paracas Peninsula (Pisco) in southern Per ú (Tello 1928, 1959; Tello and Mejía Xesspe 1979). Although ‘ Paracas’ has been used indiscriminately to describe a locat...

The "Andean Transect" project of the German Archaeological Institutes explores the settlement patterns of the the pre-hispanic populations that occupied a region in southern Peru between the provinces of Palpa on the coast and Lucanas in the highlands. More than 1500 archaeological sites, dating from the Early Archaic period to the Inka period, hav...

The current research deal with the design and development of a measurement system to determine the adequate level of pressure applied over a piezoelectric sensor to obtain continuous and non invasive arterial blood pressure values in karate-do athletes during training and competition situations. The paper focus on the characterization of the sensor...

One hundred and twenty-seven Nazca pottery and ten imitations were analysed by thermoluminescence, neutron activation analysis, X ray fluorescence, transmission electron microscopy, X ray diffraction and Mӧssbauer spectroscopy, to obtain analytical differences that allow differentiating them quickly. Additionally, 20 pieces of the Wari culture foun...

This study examines the reciprocal effects of cultural evolution, and population dynamics in pre-Columbian southern Peru by the analysis of DNA from pre-Columbian populations that lived in the fringe area between the Andean highlands and the Pacific coast. The main objective is to reveal whether the transition from the Middle Horizon (MH: 650-1000...
Chapter
During the pioneering work of Max Uhle, Julio C. Tello, and Alfred Kroeber in the Ica, Palpa, and Nasca valleys on the southern Peruvian coast, hundreds of funerary contexts mainly belonging to the Paracas, Nasca, and Wari cultures were discovered, but only few studies and analyses have been made of these large collections. The same is valid for ot...

In the present work, the results of an extensive fieldwork realized over the geoglyphs of Palpa are presented, the second biggest concentration of geoglyphs registered in the Palpa-Nasca region in the northern part of the basin of the Rio Grande. These geoglyphs were established over tilts and tableland between and lengthways of the valleys of the...

One of the most important goals of archaeology involves the reconstruction of the political and social organization of precontact societies. In recent years, there has been much discussion about the social structure and the type of political organization that existed in Nasca culture (see, e.g., Carmichael 1995; Massey 1986; Reindel and Isla 2001;...
