Researchers have used these models in many ways to investigate the temporal and geographic trends in species abundance.

Therefore the most efficient course of action may be to determine species abundance by means of geographic cluster sampling.

The technique does not recognize species abundance, only species richness.

Let "K" be a measure of the species abundance (organisms per unit area).

To monitor and manage E. swaini, it would be ideal to have a good estimate of the species abundance.

At an ecotone, species abundances change relatively quickly compared to the environmental gradient.

More research is needed to evaluate and assess current distribution, species abundance, and potential effects of threats.

Usually relative species abundances are described for a single trophic level.

Relative species abundances follow very similar patterns over a wide range of ecological communities.

The geometric series model fits observed species abundances in highly uneven communities with low diversity.
