Description acceptable. Palmer, et. al. proposed that this quantity is positively correlated to the spectral variability in the reflectance of vegetated surfaces. This quantity equals the sum of theta over theta plus n, where n ranges from 0 to J minus 1, in a non-evolutionary unified theory developed by Stephen Hubbell. This quantity is plotted against sampling effort in the collector’s curve. This quantity is measured (15[1])in OTUs when computing it from (*) rarefaction curves. In one measure, this quantity equals the inverse of the weighted harmonic mean, which equals the Hill number of order 0. This quantity is often assumed (-5[1])to follow a power-law with habitat area. This quantity is often (10[1])contrasted with evenness and dominance. For 10 points, name this simplest measure of biodiversity that does not take into account the relative abundance of organisms. ■END■ (10[1])
