New Data on the Young Volcanism in the Puna of NW-Argentina

Geologische Rundschau, 1973
The Puna of NW-Argentina is divided into a Paleozoic basement complex and a late Mesozoic-Cenozoic sedimentary cover. The sedimentary cover was affected by late fracture tectonics and, from middle Tertiary to Quaternary times, invaded by various volcanics.

Neotectonic deformation of the southern Puna Plateau, northwestern Argentina

Journal of South American Earth Sciences, 1989
Abstract Continental plateaus have been likened to pressure gauges that record the mechanical state of the lithosphere involved in mountain building. We outline the kinematic state of the southern Puna Plateau and bounding foreland provinces of the NW Argentine Andes based on surficial fault slip data and crustal seismicity.

Does food abundance determine the diet of the Puna Rhea (Rhea tarapacensis) in the Austral Puna desert in Argentina?

Emu - Austral Ornithology, 2017
ABSTRACTThe Puna Rhea (Rhea tarapacensis) is a large, flightless herbivorous bird found in the Andes Mountains of four countries, namely Argentina, Chile, Bolivia and Peru. Despite its ample distribution range, little is known about the ecological requirements of the species.

Deformation history of the Puna plateau, Central Andes of northwestern Argentina

Journal of Structural Geology, 2020
Abstract Two tectonic shortening events created the first-order structural characteristics of the Puna plateau: one in the Paleozoic and a second during the Andean Orogeny in the Cenozoic. To constrain the structural characteristics and timing of Andean deformation in the Puna plateau, we focus on differentiating these two shortening events and ...

Mid-Holocene environment and human occupation of the Puna (Susques, Argentina)

Quaternary International, 2005
Abstract Paleoenvironmental information regarding the mid-Holocene in the Puna de Atacama generally shows extreme aridity and high temperatures (“Hypsithermal”). Moreover, the absence of human occupations in certain sectors of the region suggested a “Silencio Arqueologico”, between 7500 and 5000 BP.

Eutrombicula cochinocaensis infestation in llamas (Lama glama) in the Puna region of Argentina

Veterinary Research Communications
This paper aims to describe a case of trombiculosis in llamas from the Puna region of Argentina caused by Eutrombicula cochinocaensis. Trombiculosis is a parasitic infestation caused by the larval form of trombiculid mites, commonly known as chigger mites. Six adult llamas out of eighteen (33%) were infested and showed dermatitis, hyperemia, and crusts

Effect of temperature on the locomotor performance of species in a lizard assemblage in the Puna region of Argentina

Journal of Comparative Physiology B, 2018
Locomotion is relevant to the ecology of reptiles because of its presumed influence on an organism's Darwinian fitness. Moreover, in ectothermic species, physiological performance capacity is affected by body temperature. We analyzed two components of locomotor performance in three species of lizards, Phymaturus extrilidus, Liolaemus parvus, and ...

Genetic variability at 14 STR loci in the Puna population of north western Argentina

International Journal of Legal Medicine, 2002
Frequency data of the short tandem repeat (STR) loci D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, HUMTH01, D4S243, D18S535, HUMF13A1 and D12S391 were determined in the Puna population (Andean region from north western Argentina). In this study, 5 out of the 14 loci did not meet Hardy-Weinberg expectations.
