Cushing. 1972. 35:1102–1108. Can. 27:55–112. A review of available literature suggests that rates of in-stream primary production in tropical regions are typically at least an order of magnitude greater than comparable temperate systems. How does the pH and stream flow affect primary productivity and biodiversity in the lake ecosystem? To explore how the variation in primary production within and among individual stream reaches can give rise to emergent river network productivity regimes, we scaled annual stream productivity regimes using simulated river networks.

Tropical river systems undoubtedly sit at the high end of the global productivity spectrum, and the wet and dry forest catchments they drain have the highest rates of primary production of any terrestrial biome.
