Lycium humile Phil., is an extreme halophyte plant, endemic to Argentina, Bolivia, and Chile, which grows between 2000 and 4000 m a.s.l. in saline wetlands environments. The aim of this work is to identify morpho-anatomical and histochemical adaptive characteristics of the vegetative organs of L. humile linked to its tolerance to extreme environmen...

Aim Climate change is transforming mountain summit plant communities worldwide, but we know little about such changes in the High Andes. Understanding large‐scale patterns of vegetation changes across the Andes, and the factors driving these changes, is fundamental to predicting the effects of global warming. We assessed trends in vegetation cover,...

Serie de Guías Audiovisuales de Biodiversidad de Antofagasta de la Sierra Esta serie de guías nace de compartir intereses, motivaciones y conocimientos con la población local del departamento Antofagasta de la Sierra, Catamarca. La Guía de plantas de vegas de Antofagasta de la Sierra recopila información de 61 especies de plantas vasculares que hem...

Esta guía es el resultado de muchos años de trabajo en la meseta de Huaca Huasi en las Cumbres Calchaquíes, provincia de Tucumán. La zona es representativa de la Ecoregión Altoandina de Tucumán y buena parte de Catamarca y Salta, por lo que pensamos que su utilidad puede extenderse bastante más allá del área de estudio. Incluye las especies que pue...

Parastrephia lucida, known as “romero”, “tola” o “t’hola”, “chachakoa”, “tola de río”, “tola de agua”, is a medicinal plant found in large areas in the semi-arid Puna of Argentina, Chile, Bolivia and Peru. It is part of the landscape called “tolar”, with other species of Parastrephia, Baccharis, and Fabiana. The “tolares” have been a very important...

Fabiana Ruiz & Pav. (Solanaceae) is a South American genus, growing especially in arid mountainous areas. In Argentina, 10 species are present in the High Andean, Pre-Puna, Puna, and Monte biogeographical regions, in addition to Patagonia. In this chapter reference is made to four Fabiana species, F. punensis, F. patagonica, F. bryoides and F. dens...

Ethnopharmacological relevance: B. boliviensis and B. tola are used in traditional medicine in the Argentine Puna to treat skin and soft tissue infections and inflammatory processes in humans and animals. Aim of the study: To assess the potential of phytotherapeutic preparations of Baccharis species as antifungal agents against clinically releva...

Resumen — La región reconocida geográficamente como Puna en Argentina esta subdi vidida en dos provincias fitogeográficas: Puneña y Altoandina. La provincia Puneña incluye dos subunidades, la Puna seca (precipitaciones de 100-400 mm/año) y la Puna desértica (<100 mm/año). La Puna seca es pri nci pal mente una estepa arbusti va, con Bacchari s, Fabi...

Prosopis alba (algarrobo) flours are traditional food resources from Argentina. The aim of this work was to determine the effect of particle sizes of Prosopis flour on its chemical composition and functional properties. Flours were obtained by mechanical methods (F1 to F4, >840, 840 to 500, 500 to 149 and <149 µm, respectively). F1 and F2 contain 4...

The high tropical Andes host one of the richest alpine floras of the world, with exceptionally high levels of endemism and turnover rates. Yet, little is known about the patterns and processes that structure altitudinal and latitudinal variation in plant community diversity. Herein we present the first continental-scale comparative study of plant c...

Spatial patterns in communities of aquatic macroinvertebrates of Argentinean Puna. The macroinvertebrates are a vital component of freshwater ecosystems as they contribute to the process of organic matter while serving as food for other organisms such as fish and amphibians. Unfortunately, the knowledge of the aquatic diversity is poor in the high...

Xanthium strumarium L., the main species of the genus Xanthium, is ubiquitously distributed. The aim of this study was to determine the cytotoxic effect of aerial organs of X. strumarium, grown in Cuba, against cancer cell lines and the isolation of compounds potentially responsible for this activity. Initially, an ethanol partitioning procedure yi...

Dihydroxychalcones as well as other metabolites synthesized via the phenylpropanoid pathway have a wide range of biological activities. Although this class of phenolic compounds is found in very large amounts in some tissues, their physiological significance remains unclear. This approach focused on the chemical analysis of Zuccagnia punctata leaf...

In South America, the mesocarp flour of Prosopis species plays a prominent role as a food resource in arid areas. The aim of this work was the characterization of the phenolic antioxidants occurring in the pod mesocarp flour of Chilean Prosopis. Samples were collected in the Copiapo, Huasco and Elqui valleys from the north of Chile. The samples of...

This protocol has five modules with methodologies used to conduct ecological research in high altitude grasslands in Andean ecosystems. It has been developed using standardized methodologies for grasslands around the world, including the Nutrient Network (NutNet), the International Tundra Experiment (ITEX) and the Global Research Initiative in Alp...

Fruits such as Prosopis pod have been food sources (patay, arrope, chicha or aloja) of inhabitants of arid and semi-arid lands in South America. The aims of the present study were determine some nutritional and functional properties as well as genotoxicity of flour obtained from Prosopis ripe pods that were submitted to different processing. Sucros...
