Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
This chapter provides some metrics for measuring species diversity, the most basic and important diversity component in ecological studies.

The closed forms for computing the variance of the relevant indices are also provided. Typical methods for the extrapolation of species richness are also mentioned in the text.
Keywords:
