Apropiación humana de la producción primaria en el Chaco Seco
(Asociación Argentina de Ecología, 2013-04)El Chaco Seco experimenta altas tasas de deforestación y transformación productiva. Estimamos la magnitud de la apropiación humana de la productividad primaria neta (PPN) aérea de esta región por vías directas (producción ... -
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 ... -
Changes in soil phosphorus in different forest residue management
(INIA Uruguay y Facultad de Agronomía, Universidad de la República, 2012)We analyze the short term effect of the harvest residues management on the Phosphorus (P) fractions of the soil. Four trials were installed in Northeast Argentina on Vertisols (S1), Mollisols (S2) and Entisols (S3 and S4). ... -

(REDFOR.ar - ArgentinaForestal - CONICET, 2021)La Red de Ciencia y Tecnología Forestal (REDFOR.ar) define, en su tercer objetivo específico: “Generar los mecanismos necesarios para abordar y difundir en la sociedad, el rol social, cultural e importancia ambiental y ... -
Deforestation and cattle expansion in the Paraguayan Chaco 1987–2012
(2017-04)The dry forests of Latin America are among the most dynamic deforestation frontiers in the world and are important carbon and biodiversity reservoirs. Our knowledge on the spatial patterns of deforestation and its proximate ... -
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 ... -
Glossy privet (Ligustrum lucidum) invasion decreases Chaco Serrano forest bird diversity but favors its seed dispersers
(Springer, 2020-11)Glossy privet (Ligustrum lucidum) is an aggressive invasive plant that replaces native forests and forms dense stands without understory in central Argentina. However, the consequences of these changes in terms of vegetation ... -
Intercambios de masa y energía entre la vegetación y la capa límite atmosférica en dos ecosistemas de Argentina
(Facultad de Agronomía, Universidad de Buenos Aires, 2014-11)Dentro del contexto del Cambio Global ha surgido el interés en conocer y entender la dinámica de los ecosistemas. La técnica Eddy Covariance (EC) es utilizada a nivel global para el registro continuo de los intercambios ... -
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 ... -
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 ... -
Stability and fragmentation versus demographic expansion: different phylogeographic patterns in closely related sympatric legumes (Senna) from arid and semi-arid zones of mid-latitude South America
(Oxford University Press, 2021-03-01)This is the first comparative research in which phylogeographical patterns and present and palaeoclimatic distribution were investigated in desert plants that inhabit the Argentinian Monte and Chaco biogeographic provinces. ... -
The role of soybean production as an underlying driver of deforestation in the South American Chaco
(2017-07)South America’s tropical dry forests and savannas are under increasing pressure from agricultural expansion. Cattle ranching and soybean production both drive these forest losses, but their relative importance remains ...
