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...

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...

A Study of Agrobiodiversity and the Impacts of Biophysical and Ecogeographical Factors on it in Ghalaje Protected Area / West of Iran

Reza Rostami, Korous Khoshbakht, Abdolmajid Mahdavi Damghani & Hadi Veisi · Annual Research & Review in Biology · 2013

It is considered that agrobiodiversity as a vital component for human food security is increasingly eroding and so making more attention to this section of biodiversity is necessary. This study was conducted in a protected area located in Kermanshah, Iran, in order to infer biodi...
