(Estación Experimental Agropecuaria Balcarce, INTA, 2020-11)Nuestra región al igual que muchas otras de Argentina, presenta graves problemas de degradación de sus tierras lo cual está directamente relacionado a la disminución la capacidad productiva de los suelos. Este proceso ... -
DMSO supplementation during in vitro maturation of bovine oocytes improves blastocyst rate and quality
(Elsevier, 2020-05)The molecule Dimethyl sulfoxide is widely used as drug solvent. However, its antioxidant property was poorly explored. In this study, we evaluated the effect of DMSO supplementation during oocyte in vitro maturation (IVM) ... -
DNA Barcoding of Phymaturus Lizards Reveals Conflicts in Species Delimitation within the patagonicus Clade
(Society for the Study of Amphibians and Reptiles, 2016-12)Under the DNA Barcode initiative, we used the mitochondrial locus cytochrome c oxidase I to test if this molecular marker would reliably distinguish among lizard species of the patagonicus clade of Phymaturus. Using 18 ... -
DNA damage and oxidative stress in gill cells of Cnesterodon decemmaculatus exposed to pesticides by runoff source in an agricultural basin
(Wiley, 2023-01)In our country, great concern exists about diffuse pollution cause by the great use of pesticides in rural environments. A thorough analysis is needed to generate information, know the real situation and thus, be able to ... -
Do greenhouse experiments predict willow responses to long term flooding events in the field? = ¿Experimentos en invernáculo predicen las respuestas de sauces a períodos largos de inundación a campo?
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2013-04)Flooding tolerance should be included as a trait in breeding programs in forested areas where extreme flooding events lasting several months can occur. In this context, it is difficult to carry out controlled, long-term ... -
Do light and alfalfa responses to cloth and slatted shade represent those measured under an agroforestry system?
(Springer Nature, 2011-02)Shade cloth is commonly used in agroforestry research. It produces a continuous, uniform reduced light environment. Shade cloth and a slatted structure were compared in relation to the inability to represent the light ... -
Do parapatric populations of the ticks Amblyomma tonelliae Nava, Beati & Labruna, 2014 and Amblyomma sculptum Berlese, 1888 (Acari: Ixodidae) hybridize?
(Royal Entomological Society, 2023-02-02)This work aimed to determine if the tick species, Amblyomma sculptum and Amblyomma tonelliae, hybridize along their contact zones in Argentina. Free-living adults and nymphs of A. sculptum and A. tonelliae were collected ... -
Do populations of Festuca pallescens from a rainfall gradient differ in the expression of morpho-physiological traits under drought stress?
(Elsevier, 2023-06)In arid environments, stochastic rainfall and high evapotranspiration force plants to optimize water resources. North Patagonia is characterized by a deep rainfall gradient that gives rise to environments with very contrasting ... -
Do soil carbon sequestration and soil fertility increase by including a gramineous cover crop in continuous soybean?
(Wiley, 2021-04-08)Cover cropping is a farming practice that may improve C sequestration and soil fertility, but these effects can vary under different edaphoclimatic conditions. The effects of including a winter gramineous cover crop (CC) ... -
Do Texas Angora bucks improve mohair weight and quality traits of Tajik Angora goats?
(2016)Productores de angora en Tajikistán del Norte levantan alrededor de 200,000 cabras De angora y productos alrededor de 300 toneladas de mohair. ¿Hay aproximadamente 500 productores pequeños, medios y más grandes con 100-500 ... -
Doble cultivo de maíz para silaje en el Norte de Buenos Aires
(Ediciones INTA, 2018-12)El doble cultivo de maíz para silaje fue evaluado, con y sin riego, en la rotación con verdeos de invierno. El maíz-maíz bajo riego produjo 27,2 t ha-1. La producción del primer maíz fue mayor después de avena que de raigrás ... -

Does biological nitrogen fixation modify soybean nitrogen dilution curves?
(2018)Biological nitrogen fixation (BNF) in soybean [Glycine max (L.) Merr.] represents, on average, 60% of total nitrogen (N) uptake. Nitrogen dilution curves link aboveground crop N concentration (%N) to biomass accumulation (W). ... -
Does climate change cause conflict? Damned if you do, damned if you don’t
