Environmental and anthropogenic drivers of soil methane fluxes in forests: Global patterns and among‐biomes differences
(Wiley & Sons, 2020-09)Forest soils are the most important terrestrial sink of atmospheric methane (CH4). Climatic, soil and anthropogenic drivers affect CH4 fluxes, but it is poorly known the relative weight of each driver and whether all drivers ... -
Environmental and cultivar effects on technological quality of the bread wheat (Triticum aestivum L.) produced in the Pampean plain of Argentina
(Wiley, 2021-05)The quality of the wheat grain is determined by several factors that lead to different physical, chemical and/or rheological characteristics. The aim of the work was to evaluate the effects of the type of cultivar quality ... -
Environmental assessment of maize production alternatives: Traditional, intensive and GMO-based cropping patterns
(2015-10)The evolution of maize production patterns in Argentina is evaluated over the last 25 years to compare costs, benefits, environmental performance and sustainability as well as to identify the main driving sources and ... -
Environmental conditions and beekeeping practices associated with Nosema ceranae presence in Argentina
(Springer, 2021-01)A longitudinal study was carried out in order to evaluate Nosema spp. spore counts in two key moments of the year (late autumn and spring) in honeybee colonies from five eco-regions of Argentina. Three hundred and sixty ... -
Environmental Conditions and Grazing Exerted Effects on Arbuscular Mycorrhizal in Plants at Southern Patagonia Rangelands
(Elsevier, 2022-03)Arbuscular mycorrhizal (AM) fungi play a major role in maintaining ecosystem functions. AM fungi are found in most ecosystems including rangelands currently under increasing pressures from human activities. Southern Patagonia ... -
Environmental control of malting barley response to nitrogen in the Pampas, Argentina
(2018-04)Twenty five single-year field experiments were established in order to assess the effects of nitrogen fertilization on grain yield, size, and protein concentration, and to explain its response to fertilization with soil, ... -
Environmental effects on seed yield determination of irrigated peanut crops: links with radiation use efficiency and crop growth rate
(Elsevier, 2007-08-12)In Argentina, delayed sowing causes a decrease in seed yield and in radiation use efficiency (RUE) of peanut crops (Arachis hypogaea L.), but it is not known if RUE reduction is mainly due to reduced temperature during ... -
Environmental factors regulate soilmicrobial attributes and their response to drought in rangeland ecosystems
(Elsevier, 2023-09)In ecosystems, soil microbial variables characterization are used to determine soil biological health and the response of soils to environmental stress. Although there are strong associations between plants and soil ... -
Environmental fate of glyphosate and aminomethylphosphonic acid in surface waters and soil of agricultural basins
(Elsevier, 2013-11)Argentinian agricultural production is fundamentally based on a technological package that combines no-till and glyphosate in the cultivation of transgenic crops. Transgenic crops (soybean, maize and cotton) occupy 23 ... -
Environmental gradients as “natural labs” for elucidating the regeneration dynamics of three Nothofagus species under different climatic scenarios in Patagonia
(2018-09)We work in Patagonian forests, the southernmost woody ecosystems of the world, in which three tree species have a clear altitudinal distribution. Nothofagus obliqua is frequent at 650-850 m above the sea level, N. nervosa ... -
Environmental heterogeneity modulates the effect of plant diversity on the spatial variability of grassland biomass
(Springer Nature, 2023-03-31)Plant productivity varies due to environmental heterogeneity, and theory suggests that plant diversity can reduce this variation. While there is strong evidence of diversity effects on temporal variability of productivity, ... -
Environmental influence on Merino sheep wool quality through the lens of seasonal variations in fibre diameter
(Elsevier, 2020-10)Wool production in arid and semiarid rangelands is strongly affected by environmental variability. Seasonal fluctuations of the environmental conditions drive variations in the nutritional status of the sheep, wool growth ... -
Environmental influence on reproductive traits of buffel grass facultative apomictic genotypes and its implication in plant breeding
(Wiley, 2023-10-04)Cenchrus ciliaris L., a perennial C4 grass, is one of the most widely used forage species in warm and dry regions worldwide. The widespread use of the cultivar Texas raises concerns about genetic homogeneity and vulnerability. ... -
Environmental quality and ecotoxicity of sediments from the lower Salado River basin (Santa Fe, Argentina) on amphibian larvae
(Elsevier, 2022-12)The lower Salado River basin receive agricultural, industrial and domestic waste water. So, the aim was to evaluate the quality of three sampling sites that belong to the Salado River basin (S1: Cululú stream; S2: Salado ... -
Environmental response of arbuscular mycorrhizal fungi under soybean cultivation at a regional scale
(Springer, 2022-10)Climate change, the shortage of fertilizers and reduced land for cultivation have drawn attention to the potential aid provided by soil-borne organisms. Arbuscular mycorrhizal fungi (AMF) offer a wide range of ecosystem ... -
Environmental variables influencing regeneration of Nothofagus pumilio in a system with combined aggregated and dispersed retention
(Elsevier, 2011-01-01)The current silvicultural prescriptions for Nothofagus are designed to stimulate natural regeneration by opening the canopy. One of these methods is variable retention, which can include either or both aggregated and ... -
