Introduction
I am interested in the functional aspects of the soil-plant relationships in low input agriculture. My work is focused in the evolutionary changes in the shape, structure and functioning of the root system under environmental stress, within a natural vs anthropic selection matrix. I examine little known aspects of the domestication syndrome of potential interest in agroecology such as the variations in water and nutrient use efficiency between wild and cultivated species.

Alvarez-Flores R, Winkel T, Nguyen-Thi-Truc A, Joffre R (2014) Root foraging capacity depends on root system architecture and ontogeny in seedlings of three Andean Chenopodium species. Plant Soil 380: 415-428. doi: 10.1007/s11104-014-2105-x. *Aims: Morphological and ontogenetic variation in root system architecture holds ecological significance, pa...

Plant morphology determines the access to soil resources, a feature crucial for early growth in annual species. Plant growth and root traits in little-known species of Andean chenopods were compared with the hypothesis that plants from low-resource habitats show traits that enhance resource capture. Three cultivated Chenopodium (two populations of...

The empirical evidence obtained by farmers of Huechelepún area (commune of Melipeuco, La Araucania, Chile) indicates that the specie Dasyphyllum diacanthoides, besides presenting medicinal properties, is a winter forage alternative. This property along with its status as endemic forests of Chile requires reconciling the use and conservation of this...

Quinoa thrives under a wide range of soil and climate conditions, from cold and arid areas to wet tropical regions. The adaptability of quinoa to various levels of drought is due to the differentiation of a diversity of ecotypes originating in contrasting agro-environments. Plants display various adaptive strategies to drought stress, from morpholo...

Quinoa has been a staple food for Andean populations for millennia. Today, it is a much-appreciated product on the international health-food, organic and fair-trade food markets. Quinoa producers in the southern Altiplano of Bolivia initiated this change approximately 40 years ago. On high desert land, they succeeded in developing a thriving agricu...

The debate on the environmental and social sustentainability of quinoa in its area of major world production (southern highlands of Bolivia) revived with the acceptance by the United Nations of the Bolivian proposal to declare in 2013 as the Year of the Quinoa. Public debate focused on local impacts of quinoa expansion in the Southern highlands of...

Alimento de base de las poblaciones andinas desde hace milenios, la quinua se ha convertido hoy en un producto apreciado en el mercado internacional de alimentos dietéticos, orgánicos y equitativos. Este cambio lo iniciaron los mismos productores del Altiplano Sur de Bolivia hace aproximadamente unos 40 años. En medio de un desierto de altura, ello...
