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 diversity is a combination of richness and evenness; it is species richness weighted by species evenness, and there are formulae that permit the diversity of a community to be expressed in a single number.he simplest measure of a diversity is to count the number of species. This is known as species richness. Each species, however, is not likely to have the same number of individuals in that community. One species might be represented by 1000 individuals, and another by 200, and a third by a single individual.
