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
(Elsevier, 2014-12)Variations in the chemical composition of the essential oils of Minthostachys mollis Griseb. (Lamiaceae) collected in their natural habitat in Argentina were determined using GC-FID-MS analysis. Seventy five samples collected ... -

Acantholippia seriphioides : chemical biodiversity of wild populations from the Cuyo Region in Argentina = Acantholippia seriphioides: Biodiversidad química de poblaciones silvestres de la región de Cuyo de la Argentina
(2015)Nineteen samples from the aerial parts in bloom of Acantholippia seriphioides (Verbenaceae) were collected in three provinces belonging to the Cuyo region of Argentina. The essential oils were obtained by hydrodistillation, ... -
Characterization of the repetitive DNA landscape in wheat homeologous group 4 chromosomes
(2015)Background: The number and complexity of repetitive elements varies between species, being in general most represented in those with larger genomes. Combining the flow-sorted chromosome arms approach to genome analysis ... -
Fire Regime, Climate, and Vegetation in the Sierras de Córdoba, Argentina
(2015)Wildfires are a primary disturbance in the Sierras de Córdoba, Argentina, with approximately 2 152 000 ha burned between 1993 and 2012. However, little is known about the spatial and temporal patterns of fires and their ... -

Characterization of functional SSR markers in Prosopis alba and their transferability across Prosopis species
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2015)Aim of study: The aim of the study was to characterize functional microsatellite markers in Prosopis alba and examine the transferability to species from the Prosopis genus. Area of the study: samples were obtained from ... -
Effect of allelic variation at the Glu-3 / Gli-1 loci on breadmaking quality parameters in hexaploid wheat [Triticum aestivum L.]
(2015-03)Low molecular weight glutenin subunits (LMW-GS) encoded by the Glu-3 loci are known to contribute to wheat breadmaking quality. However, the specific effect of individual Glu-3 alleles is not well understood due to their ... -
Diversity and structure of bird and mammal communities in the Semiarid Chaco Region: response to agricultural practices and landscape alterations
(Imperial College London, Gran Bretaña, 2015-03)The conversion of land from natural environments to human-managed areas has been particularly pronounced in the semiarid Chaco Region. In this context, it is critical to understand the impacts that these major changes have ... -
Structural aspects of dormancy in quinoa (Chenopodium quinoa): Importance and possible action mechanisms of the seed coat
(2015-05)Two possible sources of resistance to pre-harvest sprouting were evaluated in quinoa. They showed dormancy at harvest and significant variations in dormancy level in response to environmental conditions experienced during ... -
Effects of past and future land conversions on forest connectivity in the Argentine Chaco
(Springer, 2015-05)Context: Land-use change is the main driver of habitat loss and fragmentation worldwide. The rate of dry forest loss in the South American Chaco is among the highest in the world, mainly due to the expansion of soybean ... -
