Las especies del género Quercus constituyen uno de los grupos más abundantes e importantes de plantas leñosas de la Península Ibérica, estando su distribución determinada por la disponibilidad de agua, el tipo de suelo y la historia del manejo. El conocimiento de la variación de sus características morfo-funcionales puede ayudarnos a comprender el grado de diversificación de las especies del mismo género y los mecanismos que controlan sus patrones de distribución. Los objetivos principales de este estudio son: (i) analizar las relaciones existentes entre los diferentes rasgos funcionales dentro del género Quercus y testar cómo se ajustan a las estrategias de captación de recursos; y (ii) comprobar si existe coordinación entre los rasgos medidos a nivel de hoja, tallo y raíz. El muestreo se llevó a cabo en Sierra Morena (Córdoba) y la Sierra del Aljibe (Cádiz), cuantificándos...

Fertilization with seaweed has been shown to increase soil fertility and crop production reducing ultimately the need for inorganic fertilizers. However, contradictory results of the compost effect have been reported. In the present work, we aimed at testing the suitability of three composted algae materials obtained in a previous study as soil amendments for vines. The composted materials consisted of pruning waste (P) and seaweed (S) mixed (henceforth, P2S1, P1S1 and P1S2, referring the number to the ratio of P to S). Overall, we observed an increase in soil organic matter, phosphorus (P) and potassium (K) in the soil treated in comparison with soils with inorganic fertilization. A moderate N soil enrichment (ca. 20%) was also detected. The leaf analysis reflected generally the greatest concentrations of NPK for the organic treatments, but this was remarkable only during the first year after seaweed application. A noticeable improvement in grape production was detected especially with the P1S1 compost without compromising grape quality although a decrease in sucrose content was noted with the compost with higher productivity (e.g. P2S1 and P1S1). This slight sucrose drop could be attributable to a greater water availability mediated by the compost or to a dilution factor of the sucrose content caused by a greater number of berries in those vines. These findings suggest that although monitoring of the long-term effects is needed, the use of seaweed amendments for agriculture could offer a costeffective method for coastal municipalities to reduce excessive algae debris while also minimizing the impacts of inorganic fertilization.

Despite the importance of soil services, they are often underestimated and largely unrecognized. We introduce briefly the framework recently proposed by Schwilch et al. (2016), and present some results of the potential use of different tree species to remediate contaminated soils on Mediterranean conditions. Disruptions of biogeochemical cycles by human activities act as a direct driver of global change. The Guadiamar Green Corridor (Seville, Spain), is an example of extensive soil contamination by trace elements originated by mining activities. In the large-scale remediation and restoration plan, soil was cleaned-up, amendments were added, and trees of several native species were planted (Domínguez et al. 2008). We present some approaches to study tree-soil interactions, soil functioning and the provided ecosystem services. 1) Potential of trees for the phytostabilization of soil contami...
