WebPlotting the curve gives a way of estimating the number of additional species that will be discovered with further effort. This is usually done by fitting some kind of functional form to the curve, either by eye or by using non-linear regression techniques. WebDiversity sampling often addresses two aims: 1) comparing sites or experimental treatments, and 2) estimating overall diversity. Samples taken to address aim 1, can later be combined to address...

WebThe species accumulation curve (and others surrogate closely related, e.g. rarefaction curves, individual-based taxon sampling curves) provides useful information on the relationship diversity/sampling effort by showing the rate at which new species are found (Gotelli and Colwell, 2001; Hughes et al., 2001; Magurran, 2004). WebEstimates from ecological sampling were always lower than, but more closely approached, the values for taxonomic survey when processed to control for sampling effort (e.g. by using resampling with asymptotic curves). Thus, while ecological sampling detects fewer species than taxonomic survey (McCune & Lesica Reference McCune and Lesica 1992 ...
