Detalles del recurso


[EN]: High values cf plane species density have been recorded in Sierra Morena (SW Spain). «Dehesa" grass­lands are ranked between the highest diverse plant communities in the temperate Zone. Different models (Grime, Huston, Whittaker and Tilman) predicting plant species diversity from envi­ronmental factors (soil fertility, grazing pressure) and the evolutionary time, are discussed. Coexistence between the numerous plant species, in the «dehesa» grassland communities, is partly ex­plained by mechanisms based on equilibrium conditions and/or non-equilibrium hypothesis.
