Abstract

Considered is a multi-species assemblage in an infinite population with unknown and possibly heterogeneous species' abundance levels. A random sample of a fixed size (n) has been drawn only to realize a certain species distribution. At this stage, there are two interesting inference problems : (i) Prediction of the unknown proportion of the collective abundance of all hitherto unrealized species; (ii) Assessment of the quantum of additional units to be sampled [in terms of the sample size n] to realize a certain number of hitherto unobserved species. Finite population analogue of this problem is also worth discussing. I propose to review the available literature in this fascinating area of research.
