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) ... -
Efecto de la disponibilidad de agua sobre una gramínea invasora del caldenal
(Asociación Argentina de Ecología, 2019-04)En los últimos años, en la región semiárida central argentina se observó el incremento de especies gramíneas nativas no palatables C3 conocidas generalmente como “pajas”. Una causa posible del éxito de estas especies es ... -
Relative soil water content as a factor for wind erodibility in soils with different texture and aggregation
(Elsevier, 2019-04)The soil water content is one of the main factors influencing the beginning of soil particle movement by the wind. Although, some authors studied the effect of soil water content on threshold wind velocity and have defined ... -
Evaluación productiva de topinambur (Helianthus tuberosus L.) bajo diferentes densidades y fertilización en el semiárido central de la Argentina = Production evaluation of topinambur (Helianthus tuberosus L.) under different densities and fertilization in the central semiarid region of Argentina
(Asociación Argentina de Horticultura, 2017)El tubérculo de topinambur se considera un alimento funcional por su contenido de inulina. Dado que no posee almidón, puede incluirse en dietas de diabéticos y su harina puede utilizarse en la elaboración de productos para ... -
Actualización del límite occidental del pastizal pampeano
(Asociación Argentina de Ecología, 2016-04)Los mapas fitogeográficos y de eco-regiones actuales delimitan la distribución de los pastizales pampeanos argentinos a las provincias de Buenos Aires, Córdoba, Santa Fe, Entre Ríos, La Pampa y San Luis. En este trabajo ... -
Respuestas fenológicas de gramíneas C3 y C4 a variaciones interanuales de precipitación y temperatura
(Asociación Argentina de Ecología, 2018-08)La temperatura y las precipitaciones son factores determinantes de la fenología y la productividad de las plantas. Alteraciones climáticas leves pueden modificar de forma significativa los ciclos de crecimiento y afectar ... -
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 ... -
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 ... -
Reproductive ecology and genetic variability in natural populations of the wild potato, Solanum kurtzianum
(Wiley, 2014-03)The cultivated potato (Solanum tuberosum ssp. tuberosum) has more than 200 related wild species distributed along the Andes, adapted to a wide range of geographical and ecological areas. Since the last century, several ... -
The ecohydrological imprint of deforestation in the semiarid Chaco: insights from the last forest remnants of a highly cultivated landscape
(2016-07)The semiarid Chaco plains present one of the highest rates of forest clearing and agricultural expansion of the world. In other semiarid plains, such massive vegetation replacements initiated a groundwater recharge and ... -
Shallow groundwater dynamics in the Pampas: Climate, landscape and crop choice effects
(2016-01-01)Depending on its depth from the soil surface, shallow groundwater can represent a valuable water resource to alleviate droughts, or a stress agent that causes waterlogging and flooding in rainfed crops. Groundwater depth ... -
Weed Communities in Semiarid Rainfed Croplands of Central Argentina: Comparison between Corn (Zea mays) and Soybean (Glycine max) Crops
(2018-05)The semiarid Espinal in central Argentina, being recently transformed from natural semiarid grasslands into agriculture, represents an interesting scenario to understand the early stages of weed community assembly and its ... -
Vegetation composition and structure changes following roller-chopping deforestation in central Argentina woodlands
(2016-10)Driven by the pressure of increasing forage production, dry forests and woodlands of Argentina are suffering one of the highest deforestation rates in the world. In this study we combined field work and a remote sensing ... -
Diseño de un túnel de viento portátil para el estudio de la erosión eólica
(2016)La erosión eólica (EE) es un proceso de degradación irreversible de suelos de regiones áridas y semiáridas. Con el uso de túneles de viento portátiles es posible simular la EE controlando variables críticas como la velocidad ... -
Experiencias de largo plazo para el manejo de una hierba invasora de pastizales: El caso de Hieracium pilosella L. en la Estepa Fueguina
(2014-08)Las experiencias de largo plazo son poco frecuentes en los estudios sobre manejo de especies invasoras y resultan claves para comprender la efectividad de los controles. En este trabajo, revisitamos un experimento instalado ... -
Rainwater harvesting in Dry Chaco: Regional distribution and local water balance
(2015-12)Rainwater harvesting (RWH) has been essential for the establishment of human settlements in many dry regions of the world that lacked suitable surface or groundwater resources. A vast fraction of the South American Dry ... -
Vegetation Productivity in Natural vs. Cultivated Systems along Water Availability Gradients in the Dry Subtropics
(2016-12)The dry subtropics are subject to a rapid expansion of crops and pastures over vast areas of natural woodlands and savannas. In this paper, we explored the effect of this transformation on vegetation productivity (magnitude, ... -
Productive performance of alternative land covers along aridity gradients: ecological, agronomic and economic perspectives
(2016-11)The replacement of natural vegetation by pastures and extensive crops is generally driven by economic incentives and supported by technology improvements and multiple subsidies. However, towards areas of increasing aridity ... -
Soil dry aggregate stability and wind erodible fraction in a semiarid environment of Argentina
(2010-10)The size and stability of soil aggregates are primary factors that affect the soil susceptibility to wind erosion. Relationships among several soil properties and both the wind erodible fraction (EF) and the dry aggregate ... -
