An Equation of State Unifies Diversity, Productivity, Abundance and Biomass (data sets)
Description
Macroecological data sets, their state variables, and various calculated metabolic quantities for tests of the Maximum Entropy Theory of Ecology. These data sets are used with all relevant permissions, as detailed in the main publication. <br> The raw data files are: <br> data_statevariables_only.txt - This file contains the raw data and metadata. The 3/4 scaling is assumed, so E and B are with that scaling. For plants, the metabolic rate was obtained from empirical scaling of plant size (ie. dbh), and then the scaling relationship was used to calculate B, ie. m ~ e^(4/3). For the arthropods biomass was measured directly, and so E is derived using this scaling, i.e. e ~ m^(3/4). The 2/3 scaling is also included in separate columns. Note that because of what is measured directly, for the plants B is different for 2/3 and 3/4 scaling, while for the animals E is different. This file also includes the minimum diameter at breast height (DBH) for plant data and the minimum metabolic rate for arthropod data. <br> data_statevariables.txt - This file includes the observed values, but also the predicted biomass calculated numerically, and calculated analytically with the 0th and first order approximations (columns are pBnum, pB0, pB1). Also includes the calculated lambdas as lambda_1, lambda_2, and beta. This is the relevant file for plotting.
