(Asociación Argentina de Ecología, 2014-12)En los bosques de caldén (Prosopis caldenia) de la región semiárida central argentina, las pajas nativas no palatables C3 (Jarava ichu y Nassella tenuissima) han expandido su rango de distribución y abundancia, disminuyendo ... -
Growth dynamics of Geoffroea decorticans and Parkinsonia praecox and their response to climate in arid and semiarid environments in Argentina = Dinámica de crecimiento y relación con el clima de Geoffroea decorticans y Parkinsonia praecox en ambientes áridos y semiáridos de Argentina
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2021)Arid and semiarid environments dominate the Earth’s surface and are very vulnerable to global change. Chañar (Geoffroea decorticans) and brea (Parkinsonia praecox) are two ubiquitous woody species of these environments. ... -
Hydrological and productive impacts of recent land use and land cover changes in the semiarid Chaco: understanding novel water excess in water scarce farmlands
(Wiley, 2020-08)Over the last decades, the rapid replacement of native forests by crops and pastures in the Argentinean semiarid Chaco plains has triggered unprecedented groundwater level raises resulting from deep drainage increases, ... -
The impact of agriculture on soil texture due to wind erosion
(2015-01)Wind erosion produces textural changes on topsoil of semiarid and arid environments; however, the selection of particles on different textured soils is unclear. Our objectives were to evaluate textural changes induced by ... -
Influence of sand gradation on compaction of loess soils
(Elsevier Science, 2020-02-01)La evaluación de la interacción entre el carbono orgánico del suelo (OC), los límites de Atterberg y la textura del suelo, especialmente la gradación de la arena, en la densidad aparente máxima (BDMAX) puede mejorar la ... -
Inter-Annual and Seasonal Variation of ANPP and Leaf Nutrient Concentration in Cold-Temperate Wetlands of Tierra del Fuego
(Springer, 2018-02)We investigated the inter-annual and seasonal variation of the aboveground net primary productivity (ANPP), and leaf nitrogen and phosphorus concentrations across two different types of wet meadows (spring-fed and riparian) ... -
Inventario de metano entérico de los sistemas de producción de carne para San Luis en el año 2009
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2013-04)La contaminación y el recalentamiento del planeta es un tema que tiene gran repercusión social, abordándose la emisión de Gases de Efecto Invernadero (GEI) desde distintos ángulos. Tal es el caso de la ganadería sector, ... -
Jatropha curcas L. and J. macrocarpa Griseb: seed morphology, viability, dormancy, germination and growth of seedlings
(Scientific Research, 2018-08)To achieve a good production of a crop, it is essential to know the ability of the species to successfully complete two critical stages in the life cycle such as germination and seedling establishment. In this paper we ... -
Kernel hardness-related traits in response to heat stress during the grain-filling period of maize crops
(Crop Science Society of America, 2019-02)Postflowering heat stress causes the arrest of kernel growth, increasing kernel protein concentration and the relative abundance of γ-zeins, two biochemical traits contributing to maize (Zea mays L.) hardness. The impact ... -
Livestock Grazing Impacts on Herbage and Shrub Dynamics in a Mediterranean Natural Park
(2013-03)Shrub encroachment can be explained by the abandonment of extensive livestock farming and changes to land use, and it is a common problem in the Mediterranean mountain pastures of Europe, with direct effects on biodiversity ... -
Mastitis subclínicas en un rodeo de ovejas lecheras pampinta en la provincia de La Pampa
(Facultad de Agronomía, Universidad Nacional de La Pampa, 2021-01-01)Se han estudiado aspectos de la oveja Pampinta, una raza sintética desarrollada en la EEA de Anguil, constituida por Frisona del Este (East Friesian) y Corriedale. Es considerada de triple propósito (carne, leche y lana), ... -
Micropropagación de Saintpaulia ionantha H.Wendel var. Bangle Blue
(Facultad de Ciencias Exactas y Naturales, Universidad Nacional de Catamarca, 2013-12-01)Saintpaulia ionantha H. Wendel var. Bangle Blue, perteneciente a la familia Gesneriáceae, es una planta ornamental muy difundida en todo el mundo y posee características particulares que le confieren un atractivo especial. ... -
Modeling Rainwater Harvesting and Storage Dynamics of Rural Impoundments in Dry Chaco Rangelands
(MDPI, 2023-06)Transporting water to supply livestock is one of the great challenges of the drylands. Ranchers usually make impoundments, filled by runoff, to access freshwater for cattle supply in flat rangelands. The aim of this study ... -
Pathogenic diversity of Phytophthora sojae in the southeast of the Province of Buenos Aires
(Springer, 2020-06-08)Phytophthora sojae causes root and stem rot of soybeans. In Argentina, this pathogen has shown dramatic shifts in pathotype variability since its first discovery during the 1970s. The aim of this study was to report the ... -
Plant-soil feedback in the ‘real world’: how does fire fit into all of this?
(Springer, 2022-12-05)Aims: Plant–soil feedback (PSF) is an important mechanism controlling plant growth, vegetation dynamics, and longer-term and larger-scale patterns of plant community diversity. We know that feedback between plants and soil ... -
Plants vs. Streams: Their groundwater‐mediated competition at “El Morro”, a developing catchment in the dry plains of Argentina
(Wiley, 2021-04)Our understanding of how groundwater mediates evapotranspiration/streamflow partitioning is still fragmented and catchment studies under changing vegetation conditions can provide a useful frame for integration. We explored ... -
Potential technological use of reserves of Jatropha curcas and J. macrocarpa Griseb. seeds
