The promotion of diversified forests is gaining currency as an appropriate management strategy to improve, on the one hand, stand productivity and, on the other hand, stand adaptability to environmental variations, including changes in disturbance regimes.
In our research group we study the dynamics and functioning of mixed-forests from two different perspectives: First we are interested in advancing on the knowledge of the ecological factors driving tree-species diversification in Mediterranean forest stands, and we use, for this purpose, the long-term-managed black pine (Pinus nigra Arn. ssp. salzmannii) forest of the Catalan Pre-Pyrenees as study-case. Second, we aim to shed light on the potential changes that climate change can induce in the dynamics and functioning of the conifer-mixed forests constitutiong the montane-subalpine ecotone of the Pyrenean range. The abovementioned research lines are addressed using a multiscale approach (from the plant to the landscape level) and wide combination of methodologies and analytical approaches.
