From the arid core to the Atlantic coast of North Patagonia
Human-araucaria interactions during the Holocene in northwest Patagonia, Argentina
Araucaria araucana has long had an important role in the subsistence and cultural practices of aboriginal groups on both sides of the Andes in Southern South America. Despite its relevance, systematic studies on past human interactions with this species, which is limited to the Pehuén Forest, are lacking. This study examines the spatial pattern of A. araucana use in Northwest Patagonia from the Early Holocene to historic times, comparing it with …
Central Argentina vegetation characteristics linked to extinct megafauna and some implications on human populations
In this paper we study the relationships between plants and extinct megafauna by examining the characteristics of the vegetation in the central region of Argentina (i.e. Espinal, Monte, and Chaco phytogeographic regions). First, we study the size, shape, quantity, and characteristics of fruits and seeds. We also evaluate the presence of mechanical (spinescence and wood density) and chemical (secondary metabolic compounds) defenses against high ra…
Inferring past demographic changes at different spatial scales in Northwest Patagonia and central‐south Chile
In this study, we compare the patterns of demographic changes in populations from Northwest Patagonia and central‐south Chile throughout the Late Pleistocene–Holocene obtained from absolute dates with those resulting from molecular genealogies. We have found that temporal distributions of frequencies of absolute dates constitute a more sensitive demographic indicator than molecular data to make inferences at small spatial scales in the region. Mo…
Sexual dimorphism analysis in permanent human mandibular canines by geometric morphometrics
Sex estimation of unknown human remains is a common form of assessment in bioarchaeological and forensic practice. When remains are poorly preserved, teeth become important. Research regarding the use of teeth for sex estimation mainly uses odontometrics. Nevertheless, to date, few studies have aimed to systematically evaluate sexual dimorphism in tooth shape. The purpose of this study is to analyze and describe sexual dimorphism in the mandibula…
Spatio-temporal demographic dynamics of the human populations from Northwest Patagonia and central Chile during the Pleistocene-Holocene
Summer Camps Location and Distribution of Archaeological Sites in North Neuquén (Northwest Patagonia)
We study the bioclimatic and landscape characteristics of summer camps of modern transhumant herders from North Neuquén to generate a distribution model of upland areas suitable for herding and project their spatial distribution throughout the Holocene. With this aim, we analyzed ethnographic, bioclimatic and landscape data using habitat suitability models. The location of different types of archaeological sites was then compared with the project…
Caracterización bioarqueológica e isotópica de restos óseos humanos de un entierro del sitio tardío El Molino (Depto. Belén, Catamarca)
Se analizan los restos esqueletales hallados en una estructura excavada en el sitio El Molino, un poblado prehispánico tardío localizado en el Valle de Hualfín. El hallazgo se realizó en un sector cerrado por una pirca, en el interior de un recinto de características habitacionales, y constituye uno de los escasos ejemplos de restos humanos de un individuo adulto adecuadamente contextualizado y registrado de la región. Los estudios bioarqueológic…
Mitochondrial DNA Diversity and Evolutionary History of Native Human Populations of Argentinean Northwest Patagonia
The genetic composition of Amerindian descendants from Patagonia has long been a focus of interest, although the information available is still scarce for many geographic areas. Here, we report the fijirst analysis of the variation in the mitochondrial DNA (mtDNA) control region for an area of northwestern Patagonia, the North of Neuquén, with the aim of studying the processes and historical events that modeled the evolutionary history of these h…
Craniofacial variation, body size and ecological factors in aboriginal populations from central Patagonia (2000–200 years B.P.)
Dieta y variación morfológica craneofacial en poblaciones humanas del golfo San Matías (Patagonia, Argentina)
El objetivo de este trabajo es estudiar la variacin morfolgica craneofacial de las poblaciones humanas que habitaron la costa rionegrina del golfo San Matas (Patagonia, Argentina), y reas vecinas, durante el Holoceno tardo (3.000-400 aos AP) y su relacin con cambios en la dieta. El registro arqueolgico de esta regin se caracteriza por presentar informacin detallada de los contextos ecolgicos que permite establecer cambios en la dieta a partir de …
