  1. What’s the relationship of diversity and productivity? David Tilman Science Oct. 26, 2001, 294:843

  2. What’s the relationship of diversity and productivity? 168 plots, each 9 m x 9 m Seeded plots with 1, 2, 4, 8, or 16 native grassland species Each treatment replicated between 29 – 39 times Annually measured for 7 years: above-ground biomass total biomass number or remaining species

  3. What’s the relationship of diversity and productivity? 1, 2, 4, 8, or 16 native grassland species Annually measured for 7 years: above-ground biomass total biomass number or remaining species What are they hypothesizing? What’s the reasoning (or rationale) behind that hypothesis? What do they expect to find if the hypothesis is supported? What do they expect to find if the hypothesis is refuted? Any trends over the years?
