Extrapolation of the Species Accumulation Curve Associated to “Chao” Estimator of the Number of Unrecorded Species: A Mathematically Consistent Derivation

Jean Béguinot · Annual Research & Review in Biology · 2016

Incomplete samplings are doomed to become common practice for many inventories of biodiversity, thereby inviting to extrapolate what the rate of accumulation of newly recorded species would be if sampling was to be continued any further. For this purpose, a new derivation is prov...

Basic Theoretical Arguments Advocating Jackknife-2 as Usually being the Most Appropriate Nonparametric Estimator of Total Species Richness

Jean Béguinot · Annual Research & Review in Biology · 2016

A lot of nonparametric estimators of the number of unrecorded species after partial sampling of an assemblage of species, have been proposed in the literature. Unfortunately, these different types of estimators provides substantially divergent predictions. While empirical compari...

Extrapolation of the Species Accumulation Curve for Incomplete Species Samplings: A New Nonparametric Approach to Estimate the Degree of Sample Completeness and Decide when to Stop Sampling

Jean Béguinot · Annual Research & Review in Biology · 2015

Incomplete species samplings are deemed to remain the common practice in those groups of animals, such as small or micro- invertebrates, with numerous species that often are more or less difficult to detect in the field. Thus, extrapolating the Species Accumulation Curve as far a...
