A multivariate approach for mapping a soil quality index and its uncertainty in southern France
(Wiley, 2023-03)
Pedometricians have spent a lot of effort on mapping soil types and basic soil properties. However, end-users typically need a more elaborate soil quality index for land management. Soil quality indices are typically derived ...
A look at polyploidy and plant breeding
(Heighten Science Publications, 2022-11)
Polyploidization is a process that generates genetic variability and therefore one of the engines of biological evolution. Since polyploidization produces important changes in the phenotype, mainly an increase in the size ...
Developing a glyphosate-bioremediation strategy using plants and actinobacteria: potential improvement of a riparian environment
(Elsevier, 2022-12)
Glyphosate (Gly) and its principal degradation product, the aminomethylphosphonic acid (AMPA) were found in soils from a riparian environment in Argentina. Sixty-five actinobacteria were isolated from these soils, rhizosphere, ...
Prediction of the extractives content of Eucalyptus globulus wood using NIRbased PLS-R models. Influence of spectral range and preprocessing on the percentage of outliers detected
(Taylor & Francis, 2022-07-08)
Eucalyptus globulus is an important pulpwood source due to favorable wood characteristics, including low extractive content. However, there is significant tree-to-tree variation that can be exploited in breeding. This ...
Ampliación de la frontera agrícola e industrial en la Cuenca Antinaco - Los Colorados, La Rioja. Su implicancia en el recurso hídrico y en la energía
(Asociación Argentina de Ecología de Paisajes, 2017)
La Cuenca Antinaco-Los Colorados (CALC) es una de las áreas agrícolas y agroindustriales más importantes del Noroeste Argentino. El clima árido y la escasez de recursos hídricos superficiales generan que el recurso subterráneo ...
Evaluación y cartografía de la erosión hídrica en la Argentina
(Universidad de Morón, 2022-11-07)
La intensificación agrícola y la expansión de la agricultura hacia ecosistemas de mayor fragilidad están produciendo un in cremento de los procesos de erosión hídrica de los suelos, ocasionando la disminución de su ...
Effects of two protocols of ovulation synchronization on corpus luteum size and blood flow, progesterone concentration, and pregnancy rate in beef heifers
(Elsevier, 2023-04)
The objective of this study was to evaluate the effect of 7-day estradiol-progesterone-based [Treat(C)] and 5-day Co-Synch plus progesterone [Treat(Co-Sy)] protocols on ovulation time, pre-ovulatory follicle diameter, ...
Use of portable devices and an innovative and non-destructive index for in-field monitoring of olive fruit ripeness
(MDPI, 2023-01-12)
A new non-destructive index of absorbance difference (IAD), calculated with different wavelengths as references, near the chlorophyll absorbance peak or that for anthocyanin, has been used to determine the fruit ripening ...
Fenología y características agronómicas de almendros (Prunus dulcis) de floración tardía en una zona árida de Argentina = Phenology and agronomic characteristics of late flowering almond trees (Prunus dulcis) in an arid area of Argentina
(Asociación Argentina de Horticultura, 2023-01)
La fenología de los frutales permite conocer sus respuestas de adaptación al medioambiente. El almendro se cultiva ampliamente, extendiéndose mediante la incorporación de nuevos materiales vegetales, como sucede con ...
Developmental environment influences activity levels in a montane rodent, Phyllotis xanthopygus
(Elsevier, 2020-10)
Ambient temperature and thermal variability play a crucial role in diverse aspects of organisms’ biology. In the current context of climate change, it is critical to understand how temperature impacts traits that could ...
