History of botany scope of the subject as technology has opened up new techniques and areas of study. Modern molecular systematics, for example, entails the principles and techniques of taxonomy, molecular biology, computer science and more. Within botany there are a number of sub-disciplines that focus on particular plant groups, each with their own range of related studies (anatomy, morphology etc.). Included here are: phycology (algae), pteridology (ferns), bryology (mosses and liverworts) and palaeobotany (fossil plants) and their histories are treated elsewhere (see side bar).

Glossary of invasion biology terms Glossary of invasion biology terms The need for a clearly defined and consistent invasion biology terminology has been acknowledged by many sources. "Invasive species", or "invasive exotics", is a nomenclature term and categorization phrase used for flora and fauna, and for specific restoration-preservation processes in native habitats. "Invasion biology" is the study of these organisms and the processes of species invasion.

Terminology relates primarily to invasion biology terms with some ecology terms included to clarify
