Figure 3. Relationship of estimated temporal range or density [ETD] of a taxon to its observed temporal range or density [OTD], expressed as a function of the number of independent samples n found in OTD for critical likelihood l = 0.05 (heavier line) and also for l = 0.5 and l = 0.01 (lighter lines). For values of sample size n considered in applications here, n = 42 and n = 56, differences in ETD are not very sensitive to small changes in l.
