Abstract

The diversity of life is heterogeneously distributed across the Earth. A primary cause for this pattern is the heterogeneity in the amount of energy, or primary productivity (the rate of carbon fixed through photosynthesis), available to the biota in a given location1,2,3,4,5,6,7,8,9,10,11,12. But the shape of the relationship between productivity and species diversity is highly variable10,11,12,13,14. In many cases, the relationship is ‘hump-shaped’, where diversity peaks at intermediate productivity7,9,10,12,15,16,17,18. In other cases, diversity increases linearly with productivity4,5,6,10,11,12. A possible reason for this discrepancy is that data are often collected at different spatial scales10,12,14. If the mechanisms that determine species diversity vary with spatial scale, then so would the shape of the productivity–diversity relationship. Here, we present evidence for scale-dependent productivity–diversity patterns in ponds. When the data were viewed at a local scale (among ponds), the relationship was hump-shaped, whereas when the same data were viewed at a regional scale (among watersheds), the relationship was positively linear. This dependence on scale results because dissimilarity in local species composition within regions increased with productivity.
