Millennial-Scale Relationships of Diatom Species Richness and Production in Two Prairie Lakes

Insight into the causes and consequences of changes in aquatic biodiversity requires an improved understanding of the nature of the relationships between species richness and ecosystem function over a much longer temporal perspective than we currently possess. We used high-resolution paleoecological records from two prairie lakes to show that diatom species richness (as fossil frustules) was negatively correlated $(r^{2}=0.09-0.24,p
