How are systematics and biological and ecological features related to silica content in plants? A study of species from southern south america
(University of Chicago Press, 2020-12)
Premise of research. Plant silica content depends on the phylogenetic position of a taxon; however, biological or ecological factors may also affect it. In this work, we analyzed data on silicophytolith content from 105 ...
Silicophytoliths in Holocene peatlands and fossil peat layers from Tierra del Fuego, Argentina, southernmost South America
(Pergamon-Elsevier Science Ltd, 2013-02)
Phytolith analyses are practically absent from peatlands, except for studies developed on tropical mires and peat profiles. In Tierra del Fuego, Argentina, peatlands represent the largest surface coverage in the South ...
Amorphous silica biomineralizations in Schoenoplectus californicus (Cyperaceae): their relation with maturation stage and silica availability
(Sociedad Argentina de Botánica, 2013-06)
The factors involved on the silicification process in Cyperaceae are scarcely known. In this study we analyse the effect of maturation stage and silica availability on the production of amorphous silica biomineralizations ...
Cambios climáticos en las sierras de Córdoba (Argentina) durante el holoceno. Aportes a las reconstrucciones climáticas a través del análisis de silicofitolitos del sitio arqueológico El Alto 3
(Sociedad Argentina de Botánica, 2015-08)
El análisis de silicofitolitos es una herramienta cada vez más utilizada para la reconstrucciónpaleoclimática. Sin embargo, en Córdoba estas reconstrucciones se han realizado con otras técnicas. Eneste trabajo nos propusimos ...
Producción de alimentos y diferenciación social en el Valle de Ambato, Catamarca, Argentina (siglos VI al XI d.C.). Una contribución a la problemática a través del estudio de SilicofitolitosFood production and social differentiation in the Ambato Valley, Catamarca, Argentina (6th-11th centuries AD): a contribution to the problem through the study of Silicophytoliths
(Pascual Izquierdo-Egea, 2015-01)
En este artículo se presenta la información obtenida de los estudios fitolíticos efectuados en el sedimento de dos estructuras agrícolas prehispánicas, situadas en la vertiente occidental del Valle de Ambato, Catamarca, ...
Geochemical processes controlling silica concentrations in groundwaters of the Salado River drainage basin, Argentina
(Elsevier Science, 2001-11)
Chemical analyses of dissolved silica in the shallow groundwater of the lower part of the Salado River drainage basin indicate that silica values averaged 60 ppm. The groundwaters are oversaturated in relation to quartz, ...
Archaeometric contributions to agropastoral production research in Aguada society (Ambato Valley, Catamarca)
(Elsevier Ltd, 2018-04)
This work shows the results of a series of recently conducted archaeometric studies (camelid skeletal remains nitrogen, carbon and strontium isotopes analysis, and silicophytoliths and starches analysis to sediment recovered ...
