A dose-dependent response to MEK inhibition determines hypoblast fate in bovine embryos
(BioMed Central, 2019-07-04)Background: The segregation of the hypoblast and the emergence of the pluripotent epiblast mark the final stages of blastocyst formation in mammalian embryos. In bovine embryos the formation of the hypoblast has been ... -
A dynamic model for sodium intoxication unravels salt tolerance in grapevine (Vitis vinifera L.) rootstocks
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-12)A correct selection of salt-tolerant plants should consider the relative effects of the various existing tolerance mechanisms. When toxic ions, like Na+, reach the leaves, they affect the photosynthetic apparatus, reducing ... -
A first record of bulk atmospheric deposition patterns of major ions in southern South America
(Springer, 2019-09)Despite the importance of long-term atmospheric deposition of ions for vegetation productivity and biogeochemistry, southern South America lacks long-term deposition records. We report a 6-year-long record of atmospheric ... -
A first worldwide multispecies survey of invasive Mediterranean pine bark beetles (Coleoptera: Curculionidae, Scolytinae)
(Springer, 2020-02)Several European and Mediterranean species of pine bark beetles (Coleoptera: Curculionidae: Scolytinae) have become established in North America and the southern hemisphere, posing a novel threat to planted and naturally-occurring ... -
A Framework to tackling the synchrony between Social and Ecological phases of the annual cyclic movement of transhumant pastoralism
(MDPI, 2020-04)Transhumant pastoralism is mobile livelihood strategy in which families and their herds move seasonally from lowlands, where they settle during the winter, towards the highlands, located in mountainous areas, during the ... -
A functional classification of 63 common Poaceae in the “Campos” grasslands of South America
(Asociación Argentina de Ecología, 2019-08)The natural grasslands that form part of the “Campos” of South America contain a large number of species at the paddock level (high α diversity), but little differentiation among paddocks (low β diversity). Thus, forage ... -
A functional XopAG homologue in Xanthomonas fuscans pv. aurantifolii strain C limits host range
(British Society for Plant Pathology, 2015)Citrus canker is caused by two Xanthomonas species, Xanthomonas citri, which has become the primary pathogen where citrus canker occurs (type A citrus canker, Xc-A), and X. fuscans pv. aurantifolii (Xfa), which consists ... -
A functional–structural plant model that simulates whole- canopy gas exchange of grapevine plants (Vitis vinifera L.) under different training systems
(Oxford University Press, 2020-09)Background and Aims: Scaling from single-leaf to whole-canopy photosynthesis faces several complexities related to variations in light interception and leaf properties. To evaluate the impact of canopy strucuture on gas ... -
A fungal endophyte of a palatable grass affects preference of large herbivores
(2018-04)Temperate grasses frequently acquire resistance to herbivores through a symbiosis with epichloid fungi that produces alkaloids of variable deterrent effects. However, in those cases without apparent endophyte negative ... -
A gene-derived SNP-based high resolution linkage map of carrot including the location of QTL conditioning root and leaf anthocyanin pigmentation
(2014-12)Purple carrots accumulate large quantities of anthocyanins in their roots and leaves. These flavonoid pigments possess antioxidant activity and are implicated in providing health benefits. Informative, saturated linkage ... -
A genetic approach to the species problem in wild potato
(Wiley, 2012-07)Wild potatoes are native to the Americas, where they present very wide geographical and ecological distribution. Most are diploid, obligate out‐crossers due to a multiallelic gametophytic self‐incompatibility (S) locus ... -
A land cover map of Latin America and the Caribbean in the framework of the SERENA project
(Elsevier, 2013-05-15)Land cover maps at different resolutions and mapping extents contribute to modeling and support decision making processes. Because land cover affects and is affected by climate change, it is listed among the 13 terrestrial ... -
A leaf gas exchange model that accounts for intra‐canopy variability by considering leaf nitrogen content and local acclimation to radiation in grapevine (Vitis vinifera L.)
(Wiley, 2012-07)Understanding the distribution of gas exchange within a plant is a prerequisite for scaling up from leaves to canopies. We evaluated whether leaf traits were reliable predictors of the effects of leaf ageing and leaf ... -
A long-term sustainability assessment of an Argentinian agricultural system based on emergy synthesis
(2015-06-24)By tracking the different flows of emergy (the total amount of solar energy that was directly or indirectly required in a production process) it is possible to account for all environmental work previously involved in ... -
A meta‐analysis on the effectiveness of homofermentative and heterofermentative lactic acid bacteria for corn silage
(2018-08)Aims: This meta‐analysis aims to assess the effect of lactic acid bacteria (LAB) inoculation on fermentation parameters, microbiological composition and aerobic stability of corn silage. Methods and Results: Databases ... -
A modification of the arcsine–log calibration curve for analysing soil test value–relative yield relationships
(2017-03)This article aims to discuss the arcsine–log calibration curve (ALCC) method designed for the Better Fertiliser Decisions for Cropping Systems (BFDC) to calibrate relationships between relative yield (RY) and soil test ... -
A MODIS based tool to assess inundation patterns: an example for the Paraná Delta River
(Gerencia de Comunicación e Imagen Institucional, DG-SICyP, INTA, 2020-04)Wetlands are one of the most productive yet altered ecosystems due to human activities across the world. They rely largely on their water flow to provide several ecosystem functions. Then, to develop a land use plan that ... -
A morphological and phylogenetic analysis of Ornithodoros marinkellei (Acari: Argasidae), with additional notes on habitat and host usage
(Springer, 2018-10)Ornithodoros marinkellei was described from larvae collected on Pteronotus spp. bats in Colombia and Panama. More recently, this tick was reported in the Brazilian Amazon. Because some morphometric differences were observed ... -
A multi-criteria assessment for native forest policy analysis: the case of Caldén forest in the province of Córdoba, Argentina
(Springer Nature, 2020-06)The objective of this work is to develop a discrete multi-criteria model to evaluate dif-ferent Argentina. The application of the PROMETHEE multi-criteria method integrates a private cost–benefit analysis that describes ... -
