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.
Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary.Genetic diversity serves as a way for populations to adapt to changing environments.With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.he interdependence between genetic and species diversity is delicate. Changes in species diversity lead to changes in the environment, leading to adaptation of the remaining species. Changes in genetic diversity, such as in loss of species, leads to a loss of biological diversity.
