Overview
The purpose of this discussion is to evaluate how the authors set up an experiment to test their idea that species diversity and functional group richness may influence biomass accumulation, thus changes in biodiversity may change carbon and nitrogen sequestration. Pay careful attention to which variables the authors keep the same for all the experiments and which variable(s) they manipulate to test their idea. Look at the authors' results and decide what you think the answer is to their question... This assignment is based off the following article, Reich et al. 2004. Species and functional group diversity independently influence biomass accumulation and its response to CO2 and N. PNAS. 101(27):10101– 110106.... I will attach the assignment with the questions on it.
