Herbicide-resistant weeds from dryland agriculture in Argentina
(Wiley, 2024-01)We reviewed and performed a quantitative synthesis on herbicide-resistant weeds from rain-fed crops in Argentina. Twenty-four weed species distributed in the main extensive crops (soybean, maize, wheat, barley, oilseed ... -
PastorC-Tambo: a simplified model to assess carbon balance of dairy farms
(Ediciones INTA, 2023-12)Grazing systems have the potential to mitigate greenhouse gas (GHG) emissions and improve C balance through soil C sequestration. The inclusion of soil organic carbon (SOC) balance in farm scale models is needed to assess ... -
Comparison of Gonadotropin-Releasing Hormone versus Estrogen-Based Fixed-Time Artificial Insemination Protocols in Grazing Bos taurus Suckled Beef Cows
(MDPI, 2023-09)Fixed-timed artificial insemination (FTAI) protocols for beef cattle in South America are primarily based on estradiol esters and intravaginal progesterone-releasing devices (IVPD). The objective of this study was to ... -
Convergent Adaptation of Multiple Herbicide Resistance to Auxin Mimics and ALS- and EPSPS-Inhibitors in Brassica rapa from North and South America
(MDPI, 2023-05)Herbicide-resistant weeds have been identified and recorded on every continent where croplands are available. Despite the diversity of weed communities, it is of interest how selection has led to the same consequences in ... -
Spatio-temporal variability in the feeding strategy of Andean rodents: the role of ambient temperature and food availability
(Springer, 2023-05)Animals' diets reflect the morpho-physiological and behavioral responses used to obtain nutrients and energy. While optimal foraging theory predicts them in terms of food availability, the obligatory heat model (OHM) ... -
Reproductive flexibility in South American camelids: First records of alternative mating tactics in wild guanacos (Lama guanicoe) = Flexibilidad reproductiva en camélidos sudamericanos: Primeros registros de tácticas de apareamiento alternativas en guanacos silvestres (Lama guanicoe)
(Sociedad Argentina para el Estudio de los Mamíferos (SAREM), 2020-06)Intraspecific variation in mating behavior has been documented in diverse taxa, including ungulates. Here, we report and describe for the first time the existence of alternative mating tactics in a wild guanaco (Lama ... -
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 ... -
Male aggressiveness in a polygynous ungulate varies with social and ecological context
(Wiley, 2021-01)Aggression is a social behaviour which can be affected by numerous factors. The quality and quantity of food resources may play an important role in the aggressiveness of territorial ungulates as the defence of these ... -
Behavioral responses of two small-sized rodents, Phyllotis vaccarum and Abrothrix andina, to energy challenges of high-altitude habitats in the Andes Mountains
(Wiley, 2022-12)In mountain environments, both temperature and food availability vary strongly with altitude, leading to a major challenge to the thermo-energetic balance of organisms. In this sense, the behavioral repertoire is crucial ... -
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, ... -
Transvaginal ultrasound-guided oocyte retrieval in cattle: state-of-the-art and its impact on the in vitro fertilization embryo production outcome
(Wiley, 2022-12)Transvaginal ultrasound-guided oocyte retrieval (commonly called OPU) and in vitro embryo production (IVP) in cattle has shown significant progress in recent years, in part, as a result of a better understanding of the ... -
Constitutive overexpression of EPSPS by gene duplication is involved in glyphosate resistance in Salsola tragus
(Wiley, 2022-11)Background: Glyphosate-resistant Salsola tragus accessions have been identified in the USA and Argentina; however, the mechanisms of glyphosate resistance have not been elucidated. The goal of this study was to determine ... -
Contribution of tillers to maize yield stability at low plant density
(Wiley, 2022-08)One of the main challenges of using low plant densities in restrictive and variable environments is to maximize the use of resources in better-than-expected years. The adoption of prolific genotypes has addressed part of ... -
Tendencias del consumo argentino de hortalizas y frutas locales “Km 0” = Trends in Argentine consumption of local vegetables and fruits
(Asociación Argentina de Horticultura, 2022-05)La promoción de una alimentación adecuada que incluya una dieta rica en hortalizas y frutas (H y F), inocuas, de calidad y de origen conocido, es un aspecto fundamental para la salud de la población y representa un desafío ... -
Floristic associations and filtering ability of riparian vegetation strips = Asociaciones florísticas en franjas de vegetación ribereña y sus capacidades de filtrado
(Fundación Rómulo Raggio, 2017)The analysis of lateral flow runoff of superficial nutrients and sediments from an agricultural origin and their retention by infiltration of riparian vegetation strips are of great importance in reducing the agricultural ... -
A novel EPSPS Pro-106-His mutation confers the first case of glyphosate resistance in Digitaria sanguinalis
(Wiley, 2022-04)BACKGROUND: Digitaria sanguinalis has been identified as a species at high risk of evolving herbicide resistance, but thus far, there are no records of resistance to glyphosate. This species is one of the most common weeds ... -
