Species richness estimation: Estimator performance and the influence of rare species

Species richness estimation: Estimator performance and the influence of rare species

Species richness estimators (SREs) frequently exhibit widely different results when applied to the same data set. The lack of information on the true species number in an area hampers assessment of the performance of competing SREs. Marine invertebrates have been studied for more than 150 years on Helgoland (North Sea), and a fairly complete species list exists for this assemblage, providing a ...

Species Richness Estimation

Various models and estimation procedures for estimating the number of species in a community are reviewed under the following sampling schemes: sampling by continuous-type of efforts, sampling by individuals, and sampling by quadrats (or multiple occasions). Applications and relevant software are briefly reviewed.

The Inventory and Estimation of Plant Species Richness

Quantifying uncertainty in estimation of tropical arthropod species richness.

There is a bewildering range of estimates for the number of arthropods on Earth. Several measures are based on extrapolation from species specialized to tropical rain forest, each using specific assumptions and justifications. These approaches have not provided any sound measure of uncertainty associated with richness estimates. We present two models that account for parameter uncertainty by re...
