> Patterns in riverine fish diversity: a macroecological perspective

Here I develop a conceptual framework that views contemporary riverine fish diversity as a products of a series of filters operating at different spatial and temporal scales and combining different processes of which the heart is the drainage basin. The approach allows the general structure of diversity patterns to be broken down into structures that are specific to each scale and thus to more easily generate hypotheses concerning links between the observed structures and the processes involved. This framework should help to answer the questions that are currently being asked by society including the spread of non-native species, and the effects of global changes on the maintenance of aquatic biodiversity.
