Aim Plant elemental composition and stoichiometry is crucial for plant structure and function. We studied to what extent plant stoichiometry might be caused by environmental drivers and competition from coexisting species. [...]

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Concentrations of nutrient elements in organisms and in the abiotic environment are key factors influencing ecosystem structure and function. We studied how concentrations and stoichiometries of nitrogen (N), phosphorus (P) and potassium (K) in leaves of forest trees are related to phylogeny and to environmental factors (mean annual precipitation, mean annual temperature, forest type, and nitrogen deposition). [...]

The thermodynamics of hydrogen absorption in Pd-capped Mgfilms are strongly dependent on the magnesium thickness. In the present work, we suppress such dependency by inserting a thin Ti layer between Mg and Pd. [...]

13 p, 251.3 KB Valoración económico-ecológica de la pérdida de nutrientes básicos de los suelos santafesinos / Graciela García, Mirta (Universidad Nacional de La Plata. Facultad de Ciencias Agrarias y Forestales) ; Vázquez, Mabel Elena (Universidad Nacional de La Plata. Facultad de Ciencias Agrarias y Forestales)
La provincia de Santa Fe presenta un creciente problema de acidificación de los suelos ocasionado, en parte, por la exportación de nutrientes básicos a través de las cosechas agropecuarias. El objetivo fue evaluar el impacto de la evolución de la agricultura en la pérdida de nutrientes básicos de los suelos de los distintos departamentos y el potencial costo de su remediación. [...]
The Santa Fe province presents an increasing problem of soil acidification caused in part by the export of basic nutrients through agriculture harvests. The aims was to assess the impact of the development of agriculture in the loss of these nutrients and the potential cost of remediation. [...]
