Fig. 3 | Links between impacts, processes and responses across ecosystems discussed here. An integrative approach to infer how human impacts may alter biodiversity in terrestrial and freshwater systems via their effects on the community processes of dispersal, speciation, selection and drift. Brown lines represent the effects of human impacts on community processes (note only a subset in bold are considered here), and green and blue lines the impacts of processes of varying intensity on biodiversity outcomes in ecosystems. Numbered boxes provide evidence for each highlighted link via the references listed on the right.
