Taxonomy versus systematics

Taxonomy versus systematics

These two words are not exact synonyms but rather describe somewhat overlapping fields. Taxonomy deals with the theory and practice of describing biodiversity (including naming undescribed species), arranging this diversity intoa system of  classification, and devising identification keys. It includes the rules of nomenclature that govern use of taxonomic names. Systematics emphasizes the study of relationships postulated to exist among species or higher taxa, such as families and orders. Lundberg and McDade (1990)have presented a good summary of systematics oriented toward those interested in fishes. The two primary journals dealing with systematics of animals are Systematic Biology(formerly Systematic Zoology), published by the Society of Systematic Biologists, and Cladistics, published by the WilliHennig Society.
