In а study led by Dаve Tilmаn at the University оf Minnesоta, researchers measured a variety оf parameters every year in grassland plots that had been planted with different species richnesses. One year there was a severe drought. The researchers compared the biomass of plants in the year following the drought to the biomass of the plants in the year preceding the drought and got the following data. What are reasonable conclusions from these data? Choose "supported" or "not supported" for each statement. *numbers in graph indicate how many plots had that number of species. Plots with high species richness (compared to those with very low species richness) had greater resistance to the effects of the drought on biomass. [ans2] The drought decreased species richness[ans3] If we assume that the species-rich plots are also higher in diversity, these data support the diversity-stability hypothesis[ans4]
