Comportamiento de la vegetación en planicies inundables : impacto del anegamiento y los cambios en el uso del suelo
(Facultad de Agronomía, Universidad de Buenos Aires, 2014-10)En los ecosistemas de llanuras, como la Llanura Pampeana Argentina, los flujos en sentido vertical - transpiración y evaporación directa - son las principales vías evaporativas de salida de agua. La vegetación controla las ... -
Attribution of carbon dioxide fluxes to crop types in a heterogeneous agricultural landscape of Argentina
(Springer, 2014-10)The increasing proportion of agricultural lands worldwide makes it necessary to intensify the research concerning the carbon exchange at agricultural sites. In order to determine the Net Ecosystem Exchange (NEE) in an ... -
Spatial pattern of Pindó Palm (Syagrus romanzoffiana) recruitment in Argentinian atlantic forest: the importance of tapir and effects of defaunation
(Wiley; Association of Tropical Biology and Conservation, 2014-11)Hunting pressure, fragmentation and deforestation have caused global declines in animal abundance, and the consequences for plant communities are poorly understood. Many large‐seeded plants, for instance, depend on large ... -

Mapping a region within the 1RS.1BL translocation in common wheat affecting grain yield and canopy water status
(Springer, 2014-12)The translocation of the short arm of rye (Secale cereale L.) chromosome one (1RS) onto wheat (Triticum aestivum L.) chromosome 1B (1RS.1BL) is used in wheat breeding programs worldwide due to its positive effect on yield, ... -
Regulation of Zn and Fe transporters by the GPC1gene during early wheat monocarpic senescence
(2014-12)Background; During wheat senescence, leaf components are degraded in a coordinated manner, releasing amino acids and micronutrients which are subsequently transported to the developing grain. We have previously shown that ... -
New insights into the chemical biodiversity of Minthostachys mollis in Argentina
