Bosques monotípicos de Gonopterodendron sarmientoi: ambiente, genética y morfología de los palosantales
(Asociación Argentina de Ecología, 2022-06-26)Gonopterodendron sarmientoi —Palo Santo— es una especie forestal típica chaqueña, presente en bosques mixtos o formando densos bosques monotípicos (palosantales). Por pérdida de hábitat y alta explotación, G. sarmientoi ... -
Changes in evapotranspiration and phenology as consequences of shrub removal in dry forests of central Argentina
(Wiley, 2015-10)More than half of the dry woodlands (forests and shrublands) of the world are in South America, mainly in Brazil and Argentina, where in the last years intense land use changes have occurred. This study evaluated how the ... -
Climate mediates the biodiversity–ecosystem stability relationship globally
(2018-08)The insurance hypothesis, stating that biodiversity can increase ecosystem stability, has received wide research and political attention. Recent experiments suggest that climate change can impact how plant diversity ... -
Discrimating the biophysical signal from human - induced effects on long - tern primary production dynamics. The case of Patagonia.
(Wiley, 2021-09-01)The temporal trend of aboveground net primary production (ANPP) is frequently used to estimate the human effect on ecosystems. In water-limited ecosystems, like most grazing areas in the world, human effects act upon ANPP ... -
Implications of landscape configuration on understory forage productivity: a remote sensing assessment of native forests openings
(Springer, 2021-08)Sound management of native forests used for cattle grazing requires understanding the dynamics of forage productivity in the openings. Despite their importance, forage productivity drivers in highly heterogeneous forested ... -
Informe II. Dinámica y prospectiva de la productividad de la vegetación en la provincia de Neuquén (2000-2019)
(EEA Bariloche, 2020-01)El presente informe analiza la situación actualizada a diciembre de 2019, de un informe previo realizado en junio de 2019, de la productividad de los pastizales en la provincia de Neuquén, estimada a partir de series de ... -
NDVI Response to Satellite-Estimated Antecedent Precipitation in Dryland Pastures
(MDPI, 2023-07)Precipitation is a critical driver of vegetation productivity and dynamics in dryland environments, especially in areas with intense livestock farming. Availability and access to accurate, reliable, and timely rainfall ... -
Relationship between NDVI of Patches and Cover Area of Grasses, Shrubs and Bare Soil Components of a Semi-Arid Steppe from North-West Patagonia, Argentina
(MDPI, 2023-02)Distinguishing the contributions of different vegetation cover such as shrubs and grasses components into the primary production in arid and semi-arid rangelands is a key step to understanding changes at a landscape scale. ... -
Trend-cycles of vegetation dynamics as a tool for land degradation assessment and monitoring
(Elsevier, 2019-07)The use of time series of Normalized Difference Vegetation Index (NDVI), obtained from satellite sensors has become frequent in studies for land degradation assessment and monitoring. Linear trends of NDVI are usually ... -
Variación de las propiedades edáficas en una microcuenca: Efecto del uso de la tierra
(Asociación Argentina de la Ciencia del Suelo, 2022-11-15)El objetivo del trabajo fue evaluar en una microcuenca localizada en el partido de Rojas (Provincia de Buenos Aires), la variabilidad de algunas propiedades físicas y químicas edáficas superficiales y su vinculación con ...
