Model successfully predicts large river system fish diversity

M-M River System

The Mississippi-Missouri River System was a good study area, Fagan says, because it is the largest confluent drainage system covered by the NatureServe dataset.

The fact that we can replicate key aspects of the spatial patterns of fish biodiversity from the Appalachians to the Rockies testifies to the robustness of this approach, said Fagan.

One upshot from this work, still to be vetted in other systems, is the idea that some knowledge of the branching geometry of a river network, coupled with average runoff production, can provide crucial insights into the amount and spatial distribution of freshwater biodiversity and how that biodiversity may change as discharge patterns change.
