Table 4

F-value results of comparing Laplace and Simple Good-Turing smothing for single-year (2005_1) and five-year (2005_5) observation amounts. Cells are subdivided to hold results from each abundance quartile separately; quartile order is clockwise (see top left of table). The right-hand portion of the table summarizes means for all conditions. In 2005, 31 of the 104 Jasper Ridge species were not observed. During the five-year span only one species remained unobserved.
