Abstract

We use an extension of the generalized jackknife approach of Gray and Shucany (1972) to obtain new nonparametric estimators for the number S of species in a ecosystem of size N known. IfN is unknown it shows a biased natural value (number of observed distinct species). A limit law is rigorously proved for it and an estimator, KAprieto is proposed via the asymptotic distribution. This estimator is just used to estimate N and can be applied later to the estimators for S. The performance of the estimators for S and of the estimator KAprieto is investigated by means of Monte Carlo experiments
