Localización de embalses en cuencas de alta carga sedimentaria: el caso del río Bermejo, Argentina
Tecnología y ciencias del agua, 2010 La elección del emplazamiento de una presa en ambientes montañosos subtropicales y tropicales debe considerar ante todo la progresión de la colmatación esperable según la carga sólida que transporta un río.

New Phytologist, EarlyView.Evolution of spinescence in mimosoid legumes. Summary The evolutionary arms race between plants and herbivores led to numerous plant adaptations, including spinescence. However, the balance between herbivory and abiotic conditions in the evolution of spinescence remains unclear. We integrated phylogenetic, geographic, and trait data for 2686 species of

Plant Biology, EarlyView.In vitro‐tested photosystem II thermotolerance of seven temperate conifers indicated higher thermal thresholds in species growing in high elevations compared to those in the lowlands. Higher thermotolerance might be explained by the adaptation of species in higher elevations to extreme diurnal temperature fluctuations.

Quantitative analysis of channel characteristics of distributive fluvial systems
Sedimentology, EarlyView.ABSTRACT Distributive fluvial systems (DFSs) are characterised by a radial distributive channel pattern in planform and dominate modern‐day sedimentary basins. Where aggradation occurs, such as in sedimentary basins, there is increased preservation potential, and therefore, DFSs are hypothesised to constitute a significant portion of the continental ...
