As mentioned in the last chapter, species abundance and its probability
distribution patterns were very basic and important units in ecological studies. Thus, for
ecological studies, it is very natural and common to collect species abundance data.
However, limited sampling of species abundance could not accurately reflect the
abundance and density patterns of species in the sampling areas. Thus, it is necessary to
utilize statistical methods to infer the abundance of specie with different experimental
designs. In this chapter, I outlined the relevant statistical methods for estimating species
abundance when using different sampling strategies.
