One way to audit or create job descriptions is to conduct a job analysis. Job analysis is the process of gathering, examining and interpreting data about the jobâs tasks and responsibilities.
Species richness is a count of the number of species in a given habitat or ecosystem. Unlike species diversity, species richness does not take species abundance into account. One factor which is important to consider when measuring species richness is sampling methodology.
Species-species diversity is the variety of species in a given region or area. This can either be determined by counting the number of different species present, or by determining taxonomic diversity. Taxonomic diversity is more precise and considers the relationship of species to each other.
