A recent collaborative work leaded by Raquel Benavides has studied the recruitment paterns of four dominant tree species (Pinus uncinata, Pinus nigra, Fagus sylvatica and Quercus ilex) in seven mountainous regions in the Iberian Peninsula, along entire elevational ranges.
The main goal of this research was to analyze for each species the effect of climate, local factors (i.e. light availability, stand structure and ground cover) and the interactions among them to identify the main drivers leading the regeneration process.
The results of this study stress the need of further research for better understand how the local heterogeneity can contribute to mitigate the effects of the ongoing global warming along environmental gradients, and to avoid the natural regeneration failure.
