Metal cation concentrations improve understanding of controls on soil organic carbon across a precipitation by vegetation gradient in the Patagonian Andes por Hodges, Caitlin, Araujo, Patricia Ines, Hess, Laura J.T., Vivanco, Lucía, Kaye, Jason, Austin, Amy T.

“…Tephra-derived soils retain more organic carbon (C) than soils formed from any other parent material, but this C may be sensitive to changes in climate and land use. Here we evaluate the effects of precipitation, temperature, and afforestation on extractable metals and organic C storage in young tephra-derived soils in a temperate climate. …”

Carbon footprint of maize produced in Argentina por Bongiovanni, Rodolfo, Tuninetti, Leticia, Vigneau, Pedro, Gayo, Sofía

“…The carbon footprint (CFP) of a product, such as maize, is defined by the ISO standards as the sum of greenhouse gas (GHG) emissions and GHG removals in a production system, expressed as carbon dioxide equivalent (CO2eq) and based on a life cycle assessment using the single impact category of climate change. It is the measure of one of the impacts caused by human activities on the environment. …”

N:P:S stoichiometry in grains and physiological attributes associated with grain yield in maize as affected by phosphorus and sulfur nutrition por Salvagiotti, Fernando, Prystupa, Pablo, Ferraris, Gustavo Nestor, Couretot, Lucrecia Alejandra, Magnano, Luciana, Dignani, Damian, Gutierrez Boem, Flavio Hernán

“…Likewise, S addition did not modify the N:P or N:S stoichiometry. A significant change in the intercept of the P:S relationship was observed in response to fertilization and may be used as a tool for identifying S responsive sites using grain nutrient analysis.…”

Co-expression of bovine leukemia virus and bovine foamy virus-derived miRNAs in naturally infected cattle por Petersen, Marcos Iván, Suarez Archilla, Guillermo, Perez, C.V., Gonzalez, Diego D., Trono, Karina Gabriela, Mongini, Claudia, Jaworski, Juan Pablo, Carignano, Hugo Adrian

“…Besides, seven differentially expressed bovine miRNAs (bta-miR-375, bta-miR-133a, bta-miR-677, bta-miR-1, bta-miR-3613a, bta-miR-9-5p, and bta-miR-95) were identified between cows with high BLV proviral load and uninfected counterparts (|fold change| > 1.5 and q-value < 0.05). A comprehensive analysis of protein-protein interaction networks for genes targeted by viral and host-derived miRNAs suggests a functional convergence on key pathways related to immune response, tumorigenesis, and chromatin remodeling. …”

To chop or not to chop? Tackling shrub encroachment by roller-chopping preserves woody plant diversity and composition in a dry subtropical forest por Rejžek, Martin, Coria, Rubén Darío, Kunst, Carlos Roberto, Svátek, Martin, Kvasnica, Jakub, Navall, Jorge Marcelo, Ledesma, Roxana Ramona, Gomez, Adriana Teresita, Matula, Radim

“…The transformation of the Chaco forest degraded by shrub encroachment to a silvopastoral system by roller-chopping is changing the structure of the forest but to a large extent has retained the presence and the relative abundance of woody plant species. …”

Modelling inter-annual variation in dry matter yield and precipitation use efficiency of perennial pastures and annual forage crops sequences por Ojeda, Jonathan Jesus, Caviglia, Octavio, Irisarri, Jorge Gonzalo Nicolás, Agnusdei, Monica Graciela

“…In contrast, sequence showed lower and higher CVDM than CVAP, depending on location. Moreover, changes in DM yield due to variations of AP were higher in sequence than in alfalfa. …”

Forage yield, water- and solar radiation-productivities of perennial pastures and annual crops sequences in the south-eastern Pampas of Argentina por Ojeda, Jonathan Jesús, Caviglia, Octavio, Agnusdei, Monica Graciela, Errecart, Pedro Manuel

“…Livestock production systems of Argentina show an ongoing process of change in the composition of their forage base, with a gradual increase in the proportion of their area assigned to forage crop sequences (FCS) −in particular that involving successive winter and summer annual forage crops–, at the expense of the area assigned to perennial pastures (PP). …”

Risks of cattle babesiosis (Babesia bovis) outbreaks in a semi-arid region of Argentina por Morel, Nicolas, Mastropaolo, Mariano, Torioni, Susana Marta, Signorini, Marcelo, Mangold, Atilio Jose

“…Enzootic instability still prevails in the study area despite the drastic changes occurred in cattle production system. However, 38% of herds did reach enzootic stability; therefore, a specific epidemiological status cannot be assumed at a regional level. …”

Spring deficit irrigation in olive (cv. Genovesa) growing under arid continental climate: effects on vegetative growth and productive parameters por Pierantozzi, Pierluigi, Torres, Myriam Mariela, Tivani, Martín, Contreras Valentín, Ana Cibeles, Gentili, Luciana, Parera, Carlos Alberto, Maestri, Damian

“…Under the analyzed environmental conditions, stomatal conductance was less sensitive in young leaves than in mature leaves against changes in water availability. This fact should be considered when being used as benchmarks in olives trees submitted to water deprivation during periods with marked water constraint. …”

Using automated in-paddock weighing to evaluate the impact of intervals between liveweight measures on growth rate calculations in grazing beef cattle por Imaz, José Augusto, García, S.C., González, Luciano A.

“…These datasets were then subsampled to simulate different ILW with one LW record every: (a) 1, 2, 4, 8 and 16 weeks for calves; (b) 1, 2, 4, 8, 16 and 32 weeks for weaners; and (c) 1, 2, 4, 8, 16, 26, 32, 52 (1 year) and 208 weeks (4 years) for cows. Daily LW change (LWC) was calculated as the difference between two consecutive LW observations divided by the number of days elapsed. …”
