I am a functional plant ecologist. I have worked on diverse topics and study systems, including functional phenomorphology of Mediterranean plants, macroevolution of leaf size, multi-trait interactions, or local adaptation along altitude gradients.
Now I am trying to apply Ecological tools and concepts to gain knowledge on how crop evolution has proceeded. I am lucky on this, because it happens that modern Ecology, in comparison with Genetics, Archaeology and other disciplines, has participated comparatively little to the domestication literature. But Ecology has certainly LOTS to contribute to the understanding of domestication processes and the mode and functional consequences of plant evolution under cultivation.
Why? read this, or this, or this, or that, for a start.
Currently, I am testing whether predictions of Trait-based Ecology help to explain phenotypic differences between crops and their recognized wild progenitors, and whether domestication has impacted on the ecosystem services delivered by crops. Initial results are in several of the pdfs below. Funding for this research comes from regional (Madrid), national (Spanish government), and European agencies. Also, you can see photos of our experiments in the pictures button of the navigation toolbar.
