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.
Evenness is a measure of the relative abundance of the different species making up the richness of an area. To give an example, we might have sampled two different fields for wildflowers. The sample from the first field consists of 300 daisies, 335 dandelions and 365 buttercups.venness is a measure of the relative abundance of the different species making up the richness of an area.
