Dónde, cuándo y cómo ocurren grandes incendios en la provincia de La Pampa, Argentina. Una caracterización basada en sensores remotos.
(Asociación Argentina de Ecología, 2023-02-12)Los incendios son fenómenos catastróficos, devastadores, peligrosos y costosos para una región. A pesar de su relevancia, se conoce poco sobre su dinámica espacial y temporal en la provincia de La Pampa. El objetivo general ... -
ECOSTRESS: NASA's next generation mission to measure evapotranspiration from the international space station
(Wiley, 2020-04-06)The ECOsystem Space Thermal Radiometer Experiment on the Space Station (ECOSTRESS) was launched to the International Space Station on June 29, 2018 by the National Aeronautics and Space Administration (NASA). The primary ... -
Effects of fertilizer type on nitrous oxide emission and ammonia volatilization in wheat and maize crops
(Wiley, 2022-01-28)About half of the applied nitrogen (N) is not consumed by crops, causing environmental and economic costs. This N can be lost as ammonia (NH3) volatilization, nitrous oxide (N2O) emission or leaching, among others. This ... -
Estimación del volumen sin corteza en Eucalyptus grandis utilizando modelos de regresión con variables instrumentales en dos etapas de plantaciones de la Mesopotamia argentina
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-08)En este trabajo se ajustaron modelos de predicción de volumen total sin corteza (vtsc) y volumen total con corteza (vtcc) de árboles individuales en forma simultánea. El vtcc se ajustó en función de la altura del árbol (h) ... -
Estimation of high-resolution terrestrial evapotranspiration from Landsat data using a simple Taylor skill fusion method
(2017-10)Estimation of high-resolution terrestrial evapotranspiration (ET) from Landsat data is important in many climatic, hydrologic, and agricultural applications, as it can help bridging the gap between existing coarse-resolution ... -
First Large Extent and High Resolution Cropland and Crop Type Map of Argentina
(International Society of Photogrammetry and Remote Sensing, 2020-03-22)The availability of spatially explicit information about agricultural crops for large regions in Argentina is scarce. In particular, due to temporal dynamics of agricultural production (i.e. changes in planted crops from ... -
Forest browning trends in response to drought in a highly threatened mediterranean landscape of South America
(Elsevier, 2020-08)Deforestation is widely studied throughout the world. However, a less evident issue is the effect of climate change and drought on remnants of native forests. The objective of this work was to understand the geographic ... -
Forest strips increase connectivity and modify forests functioning in a deforestation hotspot
(Elsevier, 2021-04-28)Land use changes are occurring with unprecedented magnitude and intensity, imposing global impacts on ecosystem services (ES) and biodiversity. While the impacts of land use changes are increasingly recognized, understanding ... -
Functional syndromes as indicators of ecosystem change in temperate grasslands
(Elsevier, 2018-09-24)The lack of an organizing conceptual framework to address ecosystem changes reduces our capacity to distinguish biophysical from direct human impacts on grassland dynamics. This is particularly important for subhumid ... -
Globe - LFMC a global plant water status database for vegetation ecophysiology and wildfire applications
(2019-08-21)Globe-LFMC is an extensive global database of live fuel moisture content (LFMC) measured from 1,383 sampling sites in 11 countries: Argentina, Australia, China, France, Italy, Senegal, Spain, South Africa, Tunisia, United ... -
Globe-LFMC 2.0, an enhanced and updated dataset for live fuel moisture content research
(Springer Nature, 2024-04)Globe-LFMC 2.0, an updated version of Globe-LFMC, is a comprehensive dataset of over 280,000 Live Fuel Moisture Content (LFMC) measurements. These measurements were gathered through field campaigns conducted in 15 countries ... -
Has climate change opened new opportunities for wheat cropping in Argentina?
(Springer, 2013-03)As a result of climate change, and in particular rainfall changes, agricultural production is likely to change across the globe. Until now most research has focused on areas which will become unsustainable for agricultural ... -
Impact of land use during winter on the balance of greenhouse gases
(Wiley, 2018)The increase in atmospheric greenhouse gases (GHGs) can be mitigated by capturing CO2 from the atmosphere and/or by reducing their emissions. Replacing winter intercrop fallow by cover crops (CCs) can sequester carbon and ... -
Impacts of precipitation and temperature on crop yields in the Pampas
(2015-05)Understanding regional impacts of recent climate trends can help anticipate how further climate change will affect agricultural productivity. We here used panel models to estimate the contribution of growing season ... -
Influence of fuel conditions on the occurrence, propagation and duration of wildland fires: A regional approach
(2015-09)Wildfires affect Earth's surface every year. Fuels conditions influence fire occurrence and behavior; therefore, their characterization is important for fire risk studies. We analyzed vegetation conditions influencing fires ... -
Land cover, plant residue and soil microbes as drivers of soil functioning in temperate agricultural lands. A microcosm study
(Elsevier, 2024-01-01)Feedbacks between plants and soil microbes are critical for ecosystem regulation and restoration. Soil microbial diversity is largely dependent on plant diversity, yet these relationships have received little attention at ... -
Long-lasting floods buffer the thermal regime of the Pampas
(Springer, 2018-01)The presence of large water masses influences the thermal regime of nearby land shaping the local climate of coastal areas by the ocean or large continental lakes. Large surface water bodies have an ephemeral nature in the ... -
Modelling of the effects of environmental factors on rice grain discoloration incidence in Corrientes province, Argentina
(Wiley, 2023-01)Rice grain discoloration (RGD) is a disease of complex aetiology for which there are no resistant varieties. Due to the need to better define the environmental conditions that favour the disease, the aims of this work were ... -
