A tough travesía: Mobility constraints among late Holocene Patagonian hunter-gatherers through oxygen stable isotopes in enamel and water sources
(Elsevier, 2020-10)
Central-eastern North Patagonia is characterized by a severe environmental fragmentation due to the scarce and heterogeneous distribution of fresh water. The main local wet zones, the Negro and Colorado river valleys in ...
Does trawl fisheries affect the diet of fishes? A stable isotope analysis approach
(Taylor & Francis Ltd, 2019-06)
Trawling is the main fishing practice worldwide and its ecosystem effects have been raising concern over the past decades. Long-term impacts can be monitored through changes in the trophic structure, and several studies ...
Alternative interpretations of intermediate and positive d13C isotope signals in prehistoric human remains from southern Mendoza, Argentina: The role of cam species consumption
(The University of Chicago Press Journals, 2014-12)
During the last several years, information from stable isotopes has been used to discuss the role of maize agriculture in prehistoric economies of southern Mendoza. Because maize is one of several sources of 13C enriched ...
Paleohydrogeologic reconstruction of Triassic carbonate paleolakes from stable isotopes: Encompassing two lacustrine models
(Pergamon-Elsevier Science Ltd, 2019-11)
Reconciling interpretations of geochemical, sedimentologic, and stratigraphic observations is a common challenge with many datasets, especially those from paleolake systems. The Triassic Cerro de las Cabras and Cerro Puntudo ...
Paleodietary trends in Late Holocene hunter-gatherers from southwestern La Pampa province, Argentina. First results from the Médano Petroquímica site through stable isotope analysis (δ13C and δ15N)
(Pergamon-Elsevier Science Ltd, 2020-05-20)
The aim of this work is to explore general trends and intra-site variability in human paleodiet from Médano Petroquímica, a burial site created by pre-Hispanic hunter-gatherers and located in the southwest of La Pampa ...
