An insight into the patterns and controls of the structure of South American Chaco woodlands
(Wiley, 2022)Logging, grazing, wood extraction, and anthropogenic fires are pervasive throughout the subtropical dry vegetation of South America leading to changes in woodlands structure and ultimately its degradation. The Chac ohaco ... -
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 ... -
Carbon emissions from agricultural expansion and intensification in the Chaco
(Wiley, 2017-05)Carbon emissions from land‐use changes in tropical dry forest systems are poorly understood, although they are likely globally significant. The South American Chaco has recently emerged as a hot spot of agricultural expansion ... -
Drivers of agricultural land - use change in the Argentine Pampas and Chaco regions
(2018-02)Agricultural expansion and intensification in South America's dry forests and grasslands increase agricultural production, but also result in major environmental trade-offs. The Pampas and Chaco regions of Argentina have ... -
Effect of deforestation and subsequent land-use management on soil carbon stocks in the South American Chaco
(European Geosciences Union, 2018)The sub-humid Chaco region of Argentina, originally covered by dry sclerophyll forest, has been subjected to clearing since the end of the '70 and replacement of the forest by no till farming. Land use changes produced a ... -
Effects of past and future land conversions on forest connectivity in the Argentine Chaco
(Springer, 2015-05)Context: Land-use change is the main driver of habitat loss and fragmentation worldwide. The rate of dry forest loss in the South American Chaco is among the highest in the world, mainly due to the expansion of soybean ... -
Generación de mapas de capacidad de retención de agua útil en la Región Chaco - Pampeana Argentina
(Asociación Argentina de la Ciencia del Suelo, 2022-11-15)La disponibilidad de agua en el suelo condiciona sensiblemente la producción de cultivos agrícolas y forrajeros. En general, la capacidad de retención de agua útil (CRA) de los suelos varía fundamentalmente según su ... -
Manejo de bosques con ganadería integrada: impacto en las comunidades microbianas del suelo = forest management with integrated livestock: impact on soil microbial communities
(Asociación Argentina de la Ciencia del Suelo, 2016)El manejo de bosques polifíticos semicaducifolios en la Región Chaqueña que conservan la vegetación arbórea con ganadería integrada tiene como objetivo principal que las actividades ganaderas en zonas de bosques nativos ... -
Mapping extinction debt highlights conservation opportunities for birds and mammals in the south American Chaco
(2018-02)Habitat loss is the primary cause of local extinctions. Yet, there is considerable uncertainty regarding how fast species respond to habitat loss, and how time‐delayed responses vary in space. We focused on the Argentine ... -
Mimosa chacoënsis (Leguminosae), nueva cita para la flora Argentina
(2018-03)Mimosa chacoënsis, perteneciente a la sección Habbasia serie Rojasianae del género Mimosa, es citada por primera vez para la Argentina, en la provincia de Formosa. Esta especie, endémica de la ecorregión del Chaco Seco, ... -
Partitioning the effects of habitat loss hunting and climate change on the endangered Chacoan peccary
(Wiley, 2023-04-04)Aim: Land-use change and overexploitation are major threats to biodiversity, and cli mate change will exert additional pressure in the 21st century. Although there are strong interactions between these threats, our ... -
Recent land use and land cover change dinamics in the Gran Chaco Americano
(LAGIRS, 2020-03-24)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, ... -
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, ... -
Sistema de información para la evaluación de la calidad de suelos de textura fina bajo agricultura en siembra directa en Chaco subhúmedo, En áreas sujetas a cambios en el uso del suelo.
(2018)Con el objetivo de automatizar la evaluación de la calidad de los suelos, se generó un sistema de información (software) simple y amigable. Este sistema permite ingresar los valores de los indicadores medidos en el campo ... -
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. ... -
Trade‐offs between biodiversity and agriculture are moving targets in dynamic landscapes
(Wiley, 2020-07)Understanding how biodiversity responds to intensifying agriculture is critical to mitigating the trade‐offs between them. These trade‐offs are particularly strong in tropical and subtropical deforestation frontiers, yet ... -
Trade‐offs between biodiversity and agriculture are moving targets in dynamic landscapes [Conjunto de datos]
(2020)Understanding how biodiversity responds to intensifying agriculture is critical to mitigating the trade-offs between them. These trade-offs are particularly strong in tropical and subtropical deforestation frontiers, yet ... -
Using occupancy models to assess the direct and indirect impacts of agricultural expansion on species’ populations
(Springer, 2020-08)Land-use change is a global threat to biodiversity, but how land-use change affects species beyond the direct effect of habitat loss remains poorly understood. We developed an approach to isolate and map the direct and ...
