Natural forests loss and tree plantations: Large - scale tree cover loss differentation in a threatened dioviversity hotspot.
(IOP Publishing, 2020-12-14)Distinguishing between natural forests from exotic tree plantations is essential to get an accurate picture of the world’s state of forests. Most exotic tree plantations support lower levels of biodiversity and have less ... -
Patterns and controls of carbon dioxide and water vapor fluxes in a dry forest of central Argentina
(Elsevier, 2017-12)Covering 16% of global land surface, dry forests play a key role in the global carbon budget. The Southern Hemisphere still preserves a high proportion of its native dry forest cover, but deforestation rates have increased ... -
¿Podemos mejorar las estimaciones de las emisiones de N2O en Argentina?
(Asociación Argentina de la Ciencia del Suelo, 2023-06-02)La utilización de factores de emisión por defecto y de forma homogénea en todo el país en la estimación de las emisiones de óxido nitroso (N2O) derivadas de la aplicación de fertilizantes sintéticos en los Inventarios de ... -
Propuesta de sistematización agrohidrológica en cuencas de llanura con énfasis predial y consorciado = Proposal for agro-hydrological systematization in basins plaines with emphasis predial and consortial
(Universidad Nacional del Litoral. Facultad de Ciencias Agrarias, 2017)Existe escasa tecnología para el manejo de aguas superfi ciales en áreas de planicie extrema e inundable, aumentada por la controversia de opinión en cuanto al modo de encarar la solución de los excesos y défi cit hídricos. ... -
Quantification of the environmental effect on citrus canker intensity at increasing distances from a natural windbreak in northeastern Argentina
(Springer, 2014-07-15)Citrus canker, caused by the bacterium Xanthomonas citri pv. citri (Xcc), is an endemic quarantine disease in northeastern Argentina. The objective of this study was to quantify the effect of weather variables on mid-season ... -
Recent Land Use and Land Cover Change Dynamics in the Gran Chaco Americano
(International Society of Photogrammetry and Remote Sensing, 2020-03-22)Land transformation is one of the most significant human changes on the Earth’s surface processes. Therefore, land use land cover time series are a key input for environmental monitoring, natural resources management, ... -
Regional isoprenoid emission from Eucalyptus grandis forests in northeastern Argentina
(2016)Eucalyptus species are strong source of isoprenoid emission. The objective of the present study was to estimate isoprenoid emissions from Eucalyptus grandis forest crops in the Entre Rios province in the Mesopotamia region ... -
Relationship between biophysical parameters and synthetic indices derived from hyperspectral field data in a coastal marsh from Buenos Aires Province, Argentina
(Springer, 2016-02)Remote sensing tools allow the environmental evaluation of coastal wetlands at a landscape scale, but a deeper understanding is needed of the interactions between biophysical parameters and the electromagnetic signal. The ... -
Remote sensing and cropping practices: a review
(2018)For agronomic, environmental, and economic reasons, the need for spatialized information about agricultural practices is expected to rapidly increase. In this context, we reviewed the literature on remote sensing for mapping ... -
Revisiting sampling duration to estimate N2O emission factors for manure application and cattle excreta deposition for the UK and Ireland
(Elsevier, 2022-08-29)According to the available guidelines, good practices for calculating nitrous oxide (N2O) emission factors (EFs) for livestock excreta and manure application include that sampling duration should be of at least one year ... -
Riparian buffer strips influence nitrogen losses as nitrous oxide and leached N from upslope permanent pasture
(Elsevier, 2022-05-23)Riparian buffer strips can have a significant role in reducing nitrogen (N) transfers from agricultural land to freshwater primarily via denitrification and plant uptake processes, but an unintended trade-off can be elevated ... -
Selecting control sites for post-fire ecological studies using biological criteria and MODIS time series data
(Association for Fire Ecology, 2017)Wildland fires play a key role in the functioning and structure of vegetation. The availability of sensors aboard satellites, such as Moderate Resolution Imaging Spectroradiometer (MODIS), makes possible the construction ... -
