A study led by the Doñana Biological Station – CSIC shows that land-use diversity predicts bird species and functional richness worldwide
This relationship is independent of habitat quality and is a widespread pattern on all continents

Many studies report a decrease of native species richness in communities after plant invasion by exotic taxa, but the implications of species losses on community functional structure and ecosystem processes have been less explored. The questions addressed are: (1) what are the impacts of invasive plant taxa on the functional structure of the recipient community; and (2) are there links between such functional structure and ecosystem properties representing key ecosystem processes?
