WebDec 21, 2001 · Unless authors are confident that trapping efficiency or detection probability is the same in each habitat, and present evidence for this (Heydon & Bulloh 1997), I suggest that they use the number of individuals as the measure of sampling effort when constructing species accumulation curves. WebSampling plans are typically set up with reference to an acceptable quality level, or AQL. The AQL is the base line requirement for the quality of the producer's product. The producer would like to design a sampling plan such that the OC curve yields a high probability of acceptance at the AQL. On the other side of the OC curve, the consumer ...

In ecology, rarefaction is a technique to assess species richness from the results of sampling. Rarefaction allows the calculation of species richness for a given number of individual samples, based on the construction of so-called rarefaction curves.
