Abstract

Nickel has not been considered as a broad scale global contaminant however, ecological changes such as decrease in number and diversity of species have been observed in areas around sources of nickel emission.

The present study is aimed to study the effect of nickel on reproductive behaviour and histological changes in various organs of a sedentary polychaete Hydroides elegans.
