The accumulation of new species with increasing sampling effort can be visualised with a species accumulation curve.

The observed species richness is affected not only by the number of individuals but also by the heterogeneity of the sample.
Summary 1 One of the general characteristics of ecological communities is that the number of species accumulates with increasing area sampled.
It is the rate of increase of this new (and subsequent) species-accumulation curve as more subareas are combined which leads to the best estimate of total species richness… Aim: Species-area relationships (also known as 'species-area curves' and 'species accumulation curves') represent the relationship between species richness and the area sampled in a given community. The traditional curve-fitting approach uses parametric curves to fit a species- accumulation or species-area curve to predic t its asymptote, which is used as an estimate of species richness.

new species-accumulation curve will not only cover a larger area, but will usually also lie above that for one subarea taken alone.
