Woody vegetation dynamics in the tropical and subtropical Andes from 2001 to 2014: Satellite image interpretation and expert validation

Global Change Biology, Volume 25, Issue 6, Page 2112-2126, June 2019., 2019
The interactions between climate and land‐use change are dictating the distribution of flora and fauna and reshuffling biotic community composition around the world. In the Andes of South America, we found a net increase in woody vegetation above 1000 m. While climate change has likely contributed to this increase, especially at higher elevations, land‐

Climatic Droplet Keratopathy in Argentina: Involvement of Environmental Agents in Its Genesis Which Would Open the Prospect for New Therapeutic Interventions

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
Climatic droplet keratopathy (CDK) is a degenerative corneal disease of unknown etiology. We described CDK for the first time in Latin America in the Argentinean Patagonia (El Cuy). A deeper knowledge of CDK pathogenic mechanisms will provide new therapeutic strategies.

New Data on Food Consumption in Pre‐Hispanic Populations from Northwest Argentina (ca. 1000–1550 A.D.): The Contribution of Carbon and Nitrogen Isotopic Composition of Human Bones

Journal of Anthropology, Volume 2013, Issue 1, 2013., 2013
We present data on carbon and nitrogen isotopic composition of human bones from Tolombón (Calchaqui Valley, Salta) and Esquina de Huajra (Quebrada de Humahuaca, Jujuy) sites located in Northwest Argentina (NWA). Both are complex archaeological residential settlements ascribed to the Regional Development Period (ca.

Geoelectric Exploration of the Purísima‐Rumicruz District, Jujuy Province, Argentina

International Journal of Geophysics, Volume 2012, Issue 1, 2012., 2012
Purísima‐Rumicruz district consists of several polymetallic veins, rich in copper and lead. The veins have a breccia texture and are located in shear bands, with locally high concentrations of sulfides in a carbonatic gangue. The host rock of the veins consists of a black shale sequence with thin levels of fine sands, with a low degree of metamorphism,
