Aitor Ameztegui will defend his PhD Thesis next july 17th at the Forest Sciences Center of Catalonia (CTFC). Aitor has developed his PhD project «Forest dynamics at the montane-subalpine ecotone in the Eastern Pyrenees«, in the FiDBosc group, under supervision of Dr. Lluís Coll, researcher from CTFC and associated researcher from CREAF.

The main objective of this thesis was to gain a better understanding of the dynamics of mixed-conifer forests constituting the montane-subalpine ecotone of the Pyrenees. For this, we identified the main environmental factors that drive the dynamics of these communities to then assess how changes in these factors may affect their future structure and composition. This work was done using a multiscale approach that allowed detecting the key factors determining the dynamics of these systems across different biological scales.

All the information gathered across the different scales was used to parameterize an individual-based, spatially-explicit model of forest dynamics (SORTIE-ND) in order to simulate the future dynamics of the studied forests.The results of the simulations support the predictions of future biome changes in the Pyrenean subalpine forests, since A. alba and P. sylvestris may find appropriate conditions for colonizing mountain pine dominated stands due to land-use change-related forest densification and climate warming, respectively.

El cambio climático amenaza las setas del Pirineo

El canvi climàtic afecta de manera contundent la producció de bolets dels boscos ubicats a major altitud del Pirineu, segons apunta una recerca liderada pel CTFC i la Universitat de Lleida (UdL) i on ha intervingut el nostre investigador Miquel de Cáceres.

Las olas de calor apagan el latido de los árboles centroeuropeos

Cierra los ojos y piensa en el ser vivo más sólido que conoces. ¿Has pensado en un árbol? Sólido, inmóvil e impasible al paso del tiempo. Nada más lejos de la realidad y es que los troncos de los árboles laten, se contraen de día cuando se vacían de agua y se dilatan de noche al llenarse por las raíces.
