Vegetation responses to variations in climate: A combined ordinary differential equation and sequential Monte Carlo estimation approach por Bruzzone, Octavio Augusto, Perri, Daiana Vanesa, Easdale, Marcos Horacio

“…Differences in this climate-vegetation relationship were recorded among different cases: (1) a marginal and decreasing sensitivity to temperature and radiation, respectively, but a high sensitivity to water availability; (2) high and increasing sensitivity to temperature and water availability, respectively; and (3) a case with an abrupt shift in vegetation dynamics driven by a progressively decreasing sensitivity to water availability, without any changes in the sensitivity either to temperature or radiation. …”

Effect of temporal and spatial noise colour in insect outbreak frequency por Bruzzone, Octavio Augusto, Righetti, Tomás, Faltlhauser, Ana Claudia, Aguirre, María Belén, Sosa, Alejandro Joaquin

“…For example, droughts can weaken plant defences making them more susceptible to insect herbivore attacks. As the climatic-driven effects on plant populations are correlated to time and space, not only the type of variability but also its magnitude, are of key importance for the appearance of this phenomenon. …”

Evidence for extensive genetic diversity and substructuring of the Babesia bovis metapopulation por Flores, Daniela, Minichiello, Y., Araujo, Flabio Ribeiro de, Shkap, V., Benitez, Daniel Francisco, Echaide, Ignacio Eduardo, Rolls, P., Mosqueda, J., Pacheco, Maria Gabriela, Petterson, Maria Elizabeth, Florin-Christensen, Mónica, Schnittger, Leonhard

“…A panel of nineteen micro- and minisatellite markers was used to estimate population genetic parameters of eighteen parasite isolates originating from different continents, countries and geographic regions including North America (Mexico, USA), South America (Argentina, Brazil), the Middle East (Israel) and Australia. For eleven of the eighteen isolates, a unique haplotype was inferred suggesting selection of a single genotype by either in vitro cultivation or amplification in splenectomized calves. …”

Anuran responses to spatial patterns of agricultural landscapes in Argentina por Suarez, Romina Paula, Zaccagnini, Maria Elena, Babbitt, Kimberly J., Calamari, Noelia Cecilia, Natale, Guillermo Sebastian, Cerezo, Alexis, Codugnello, Nadia, Boca, Rosa Teresa, Damonte, María Jimena, Vera Candioti, Josefina, Gavier Pizarro, Gregorio Ignacio

“…Results: Anuran richness was lower in the landscape with greater level of agriculturalization with reduced amount of forest cover and stream length. This pattern was driven by the lower occurrence and calling activity of seven out of the sixteen recorded species. …”

The ecohydrology of ecosystem transitions: a meta‐analysis por Viglizzo, Ernesto Francisco, Nosetto, Marcelo Daniel, Jobbagy Gampel, Esteban Gabriel, Ricard, Maria Florencia, Frank, Federico Carlos

“…As a novel finding, we demonstrate that ecohydrology, as a determinant of transition, is a factor that operates at a hierarchical level higher than that of the human‐driven disturbance. A synthetic graphical model was proposed to characterize resilience (the capacity of ecosystems to withstand transition) in the three study climatic regions.…”

Water and radiation use efficiencies in maize: breeding effects on single-cross Argentine hybrids released between 1980 and 2012 por Curin, Facundo, Severini, Alan David, Gonzalez, Fernanda Gabriela, Otegui, María Elena

“…Results demonstrated that breeding efforts, which have been driven almost exclusively by GY improvement, had no evident effect on the crop water use but had clear effects on crop biomass production and its partitioning. …”

Aeolian Remobilisation of the 2011-Cordón Caulle Tephra-Fallout Deposit: Example of an Important Process in the Life Cycle of Volcanic Ash por Dominguez, Lucia, Bonadonna, Costanza, Forte, Pablo, Jarvis, Paul Antony, Cioni, Raffaello, Mingari, Leonardo, Bran, Donaldo Eduardo, Panebianco, Juan Esteban

“…Although volcanic eruptions represent short periods in the whole history of a volcano, the large amount of loose pyroclastic material produced, combined with aeolian processes, can lead to continuous, long-lasting reworking of volcanic products. Driven by wind, these processes significantly influence the geomorphology and prolong the impacts of eruptions on exposed communities and ecosystems. …”
