Behavioral and physiological changes in the passerine Agelaioides badius following the ingestion of coated seeds with imidacloprid in a 30-day experiment
(Elsevier, 2023-12)The wide use of neonicotinoid seed treatment represents a hazard for farmland birds that feed on treated seeds. This study aimed to characterize the long-term effects of the neonicotinoid imidacloprid (IMI) in the passerine ... -
Variation in seed dormancy of Chaco seasonally dry forest species: Effects of seed traits and population environmental conditions
(MDPI, 2023-04-27)The persistence of subtropical seasonally dry forests urgently requires the implementation of ex situ conservation and restoration programs. We studied variation in seed traits and dormancy of six native species growing ... -
Vegetated roofs as a nature-based solution to mitigate climate change in a semiarid city
(Elsevier, 2023-05-18)cumulating greenhouse gasses. Global warming has been related to increased carbon dioxide (CO2) emissions [1,2]. Urban areas emit a significant amount of greenhouse gasses, including 78% of total CO2 emissions [3]. Transport, ... -
Cover crop species affect N2O emissions at hotspot moments of summer crops
(Frontiers Media, 2022-06-01)The use of cover crops, combined with low N fertilization and no-tillage, reduces theenvironmental impacts of agriculture. Legume cover crops provide N to the agroecosystem and allow N fertilization to be reduced without ... -
¿Podemos mejorar las estimaciones de las emisiones de N2O en Argentina?
(Asociación Argentina de la Ciencia del Suelo, 2023-06-02)La utilización de factores de emisión por defecto y de forma homogénea en todo el país en la estimación de las emisiones de óxido nitroso (N2O) derivadas de la aplicación de fertilizantes sintéticos en los Inventarios de ... -
How to Improve Soil Anti-adhesion by Studying the Micro Relief of the Cuticle Surface of Digging Beetles: Exploring the Sulcophanaeus batesi Pronotum Using Translucent Replicas
(Oxford University Press, 2023-09-13)For some years, we have been studying the microtopography of soil diggers beetles fromArgentina to find the anti-adhesion pattern to decrease a soil particle adhesion for agricultural machinery components. In 2018, we ... -
How does post-flowering sources/sink manipulation affect grain weight and commercial quality in Argentinean bread wheat genotypes with different baking aptitude?
(Elsevier, 2023-06-29)Context: Wheat is a crop of vital importance for food security. In contrast to the accumulated knowledge for yield determination, the effect of variations in the source/sink (S/S) ratio on grain quality, and its interaction ... -
Breeding value predictive accuracy for scarcely recorded traits in a Eucalyptus grandis breeding population using genomic selection and data on predictor traits
(Springer, 2023-07-18)Genomic selection methods are particularly useful for traits that are difcult or expensive to measure. We investigated the impact of using predictor growth traits and/or genomic information to increase the breeding value ... -
On-farm assessment of yield and quality traits in durum wheat
(Wiley, 2023-08-15)Durum wheat is key source of calories and nutrients for many regions of the world. Demand for it is predicted toincrease. Further efforts are therefore needed to develop new cultivars adapted to different future scenarios. ... -
Impact of different on-farm management practices on breat wheat quality: a case study in the Yaqui Valley
(Wiley, 2023-08-15)Continuous development of new wheat varieties is necessary to satisfy the demands of farmers, industry, and consumers. The evaluation of candidate genotypes for commercial release under different on-farm conditions is a ... -
