Discrimination of species is referred to as micro-taxonomy. Classification of organisms above the species level is called macro-taxonomy. There are three levels of taxonomy. Alpha taxonomy deals with characterization and naming of species.

Beta taxonomy deals with arranging of species into a natural system of lower and upper taxa. Gamma taxonomy deals various biological aspects of taxa, ranging from study of intra-specific population to studies of speciation and of evolutionary rates and trends.
