Norman Myers argued that the global value of this quantity could be maintained by monitoring its value for regions in which this quantity is exceptionally high. The extent to which this quantity is inflated by the presence of one or two unique samples is quantified by the Chao1 parameter. This quantity’s tendency to increase at a region’s edges favors several small regions for maximizing this quantity in the SLOSS debate. Larger and less remote islands are predicted to have higher values (10[1])for this quantity (10[1])due to migration from the mainland in island biogeography. (10[1])The Cape Floristic Region and Madagascar are “hotspots” for this ecological (10[1])quantity, (10[1])which tends to be maximized (10[1])in tropical climates. For 10 points, name this quantity that measures the abundance and variety of species in a region. ■END■
