Grass-shrub coexistence: understanding root distribution in ecological sites of the Semiarid Chaco, Argentina
(Taylor & Francis, 2021-12)The objective of this study was to analyze the root distribution of grasses and shrubs, at different soil depths, in two ecological sites (ES): highland (forest) and lowland (grassland). The root density (RD) estimation ... -
Grasslands and Open Savannas of the Dry Chaco
(Elsevier, 2020-06-26)The Dry Chaco is mostly known as a forested ecosystem. However it includes natural grasslands, savannas, scrublands, and wetlands. With one of the highest global deforestation rates in the last two decades and only 12% of ... -
Grazing and ecosystem service delivery in global drylands
(American Association for the Advancement of Science, 2022-11-25)Grazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may ... -
Grazing and neighborhood interactions limit woody encroachment in wet subtropical savannas
(2014-12)Woody encroachment in savannas is a worldwide concern, and there is growing consensus that anthropogenic activities play a central role in changing tree – grass interactions. We evaluated the influence of livestock grazing ... -
Grazing diverse combinations of tanniferous and nontanniferous legumes: implications for foraging behavior, performance, and hair cortisol in beef cattle
(American Society of Animal Science, 2021-10-17)A diversity of forages with different types and concentrations of nutrients and plant secondary compounds may lead to complementary relationships that enhance cattle performance and welfare. We determined whether grazing ... -
Grazing increases evapotranspiration without the cost of lowering soil water storages in arid ecosystems
(2017-09)Grazing is the predominant land use practice in arid environments; however, there are relatively few studies of grazing effects on ecosystem functioning. We assessed the impact of grazing on soil moisture, evapotranspiration ... -
Grazing intensity levels influence C reservoirs of wet and mesic meadows along a precipitation gradient in Northern Patagonia
(Springer, 2015-06)Wet meadows are important ecosystems for forage production and as carbon reservoirs in semi-arid areas. In Patagonia, Argentina, large areas of wet meadows have been classified as overgrazed by livestock. The objective of ... -
Green bridge crops to manage corn nitrogen nutrition in the Southeastern Argentinean Pampas
(Elsevier, 2022-01-17)An ecological intensification of agriculture through the use of green bridge crops (GBC) between cash crops is a way to improve resource use efficiency. This study aimed to assess vetch (Vicia villosa Roth.) (Ve), oat ... -
Green extraction of nutritional and antioxidant valuable compounds from wine by-products
(Taylor & Francis, 2019-09-23)The world wine-growing area in 2017 stands at 7.5 million hectares, with Spain having the largest number (967,000 ha), around 13% of the world surface, ranking ahead of countries, such as China (870,000 ha) and France ... -
Green spaces in a tertiary care children`s hospital benefits, taxonomic survey, and perspective
(2018-04)El contacto del ser humano con espacios verdes naturales tiene un efecto físico, mental y social beneficioso. Con el primer objetivo de conocer las especies vegetales de los jardines del Hospital de Pediatría Garrahan ... -
Greenhouse gas emissions from beef grazing systems in semi-arid rangelands of central Argentina
(MDPI, 2018-11)The livestock sector can be a major contributor to the mitigation of greenhouse gas (GHG) emissions. Within the sector, beef production produces the largest proportion of the livestock sector’s direct emissions. The objective ... -
Greenhouse Gas Emissions from Green-Harvested Sugarcane With and Without Post-harvest Burning in Tucumán, Argentina
(2014-06)Concentrations of greenhouse gases (GHG) in the atmosphere are increasing due to anthropogenic actions, and agriculture is one of the most important contributors. This study quantified GHG emissions from green-cane harvested ... -
Greenhouse gasses emissions and energy balances of a non-vertically integrated sugar and ethanol supply chain: A case study in Argentina
(2013-06-01)In order to address society's concerns regarding the sustainability of sugar and ethanol production and use, this paper calculates the energy and greenhouse gasses (GHG) emissions' balances of a non-vertically integrated ... -
