Species area curve

Description

A standard observation in ecological fieldwork is that as the area scanned increases, the number of species of any given taxon (here birds) seen in that area increases but at a decreasing rate. Such empirical relationship can be exploited to estimate total number of species (species richness). For more details refer the web link indicated below.
