Through this 3D animation video the laboratory of Ecology and Evolution of plants and Divulgare Group at the University of Vigo intended to show the role, unknown to the general public, of the lizards, as modelers plant landscape on island ecosystems. These reptiles change their diet in insular environments incorporating many fleshy fruits. By eating these fruits, they disperse their seeds with a fantastic result for the plants. The video shows the results of a research project that the laboratory of Ecology and Evolution of plants at the University of Vigo has done in the Atlantic Islands of Galicia National Park (Spain) with funding from the Autonomous Organisation of National Parks.
