[Henderson's] a measure of the biological diversity (generally the species diversity) within an environment. There are various types of diversity index, which are calcu­lated in various ways from the number of species present and their relative abund­ance (see e.g. Simpson diversity index). Such indices can be used to detect eco­logical changes due e.g. to stress on an environment. cf. biotic index.
