Alphataxonomical principles

Alpha taxonomy is the discipline within biology concerned with delimiting, naming and describing organisms. It constitutes the basis for conducting systematic studies on our biodiversity at any level from cell to ecosystem. The course comprises a thorough discussion on species concepts, in biological terms as well as with a philosophical angle. Naming organisms follow international rules that are published in so called Nomenclatural Codes. The main principles for naming taxa within different organism groups will be presented. Examples of the importance of reference specimens and detailed labelling for taxonomical work are given. Descriptions of species often follow a number of rules that are dependent on the group being studied. Exercises in taxon description, even formalised ones using computers as a tool, are given. Keys used for species identification are an important link between the taxonomical expertise and users within science as well as the rest of society. The theoretical part of the course, the first two weeks, is given on distance. The project work and written exam, the third week, are done locally at the university where you have been admitted to the course or the master programme in biodiversity and systematics.
