Study Notes
Microtaxonomy
- Focuses on the classification and categorization of organisms at the species level
- Involves the study of subtle variations, morphological traits, genetic differences, and ecological adaptations among individuals or populations within a species
Infraspecific Ranks
- Subspecies, variety, and form are subranks under the species level in the biological hierarchy
- Subspecies: used in both animal and plant kingdoms
- Variety: used in plant kingdom
- Form: used in plant kingdom
History of Infraspecific Categorization
- Carolus Linnaeus (1751) recognized varieties in botany
- Friedrich Ehrhart (1780-1789) used the rank of subspecies in botanical literature
- Christiaan Hendrik Persoon (1805) used the term subspecies in his Synopsis Plantarum
- Friedrich Anton Wilhelm Miquel (1843) used the term form or forma
- Henry Bates (1861) recognized subspecies in zoology
