OLM 12.1  Comparison of species numbers in samples

In the discussion of diversity patterns in Ch12Divers we have omitted the difficulties stemming in the fact that it is just samples whose species numbers can be compared in diversity studies, not the entire communities. Just as the finite number of individuals in an offspring generation do not necessarily inherit all the alleles present in the parent population (TBox 11.4, p.243), the species of a community are usually not all represented in the samples (Figure 12.1.1). This OLM deals with the methods of making comparative estimates of diversity even in the face of such difficulties.
