23、11 EN 16493:2014 (E) 4 Introduction Assessments of ecological quality of aquatic systems are generally based on the taxonomic composition of the available, most relevant communities like macro-invertebrates, phytobenthos and phytoplankton. Consequently, the recording of taxonomic names is a major ac

24、tivity in hydrobiological studies. Scientific names of animals and plants should be unambiguous and unique to ensure effective communication. To achieve this goal internationally accepted rules have been established in nomenclatural codes, the most important of which is the International Code of Bot

25、anical Nomenclature (ICBN 1, from 2012 renamed ICN: International Code of Nomenclature for algae, fungi, and plants 2) and the International Code of Zoological Nomenclature (ICZN 3). Various editions of each of these codes exist; a new edition of the Botanical Code is published every 6 years. The un

26、familiarity of most technicians and ecologists with these codes is a major cause of the abundance of problems in ecological assessments and data storage. Unambiguous exchange of data between biological databases is often impossible and recorded names are often meaningless due to inaccurate applicati

27、on or the complete disregard for nomenclatural rules. This European standard, therefore, aims at providing guidance to both technicians and ecologists on the proper writing, use and interpretation of taxonomic names to allow effective scientific communication at all levels. DIN EN 16493:2014-11 EN 1

28、6493:2014 (E) 5 1 Scope This European Standard describes the most relevant rules of the Botanical and Zoological Codes necessary for unequivocal recording of biodiversity in the aquatic environment. Furthermore, guidance is given on how to deal with taxonomic changes in relation to recorded taxonomi

29、c names. NOTE A Code only affects taxonomic changes carried out in the period covered by that particular edition of the Code. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 taxonomy scientific discipline of identifying and naming species, an

34、1 General Taxonomic names are scientific names of taxonomic entities. The most important entities (ranks) are written from low to high in the taxonomic hierarchy (in Latin, with common name given in brackets): Forma (form); Varietas (variety); Subspecies (subspecies); Species (species); Genus (genus

35、); Familia (family); Ordo (order); Classis (class); Phylum (phylum, sometimes indicated as Divisio or division); Regnum (kingdom). Taxonomic names shall meet the requirements set by the Codes, concerning correct (Latin or Latinized) spelling, gender, the use of punctuation marks, etc. (compare also

36、Stearn 2004 4). In principle, only validly published and legitimate names should be used. Occasionally the only available name for a taxon does not meet the rules of the respective Code, but is still widely used. Where this is the case, the only available taxon should be used. 3.2 Taxon name A disti

37、nction should be made between names at the level of genus and higher, species names and the names of infra-specific taxa. Scientific names of genera and higher taxa (family, order, class, etc.) are single (but occasionally compound) names, written with an initial capital letter. A genus may be subdi

38、vided. The name of such a subdivision is a combination of a generic name and an infra-generic name also written with an initial capital letter. A connecting term (subgenus, section, etc.) is used to denote the rank. When it is appropriate to indicate the name of a subdivision of the genus in questio

39、n, the infra-generic name should be placed in parentheses between the two. For the subdivision of other taxonomic ranks, the respective Codes should be consulted. The scientific name of a species is a combination of a generic name and a specific epithet (a “binomial“), the latter without an initial

40、capital letter. Scientific names of infra-specific taxa (all taxa below the level of species, DIN EN 16493:2014-11 EN 16493:2014 (E) 7 such as subspecies, varieties, etc.) are combinations of three name parts (in zoology a trinomen and in botany a ternary name): a generic name and two epithets. In i

41、nfra-specific zoological taxon names the three component names are placed in succession, indicating that a subspecies is being referred to. In infra-specific botanical taxon names, an indication of the taxonomic level should be given between the second and third name by abbreviated linking terms as,

42、 e.g. “subsp.” for subspecies; “var.” for variety; or “f.” for forma. Epithets might be of very different origin; an important rule is that the gender of the genus name prescribes that of the epithets. Names of taxa at the level of genus and lower should be written in italics. Names of higher taxa a

43、nd terms of taxonomic rank should be written in Roman type. When a species name or different species names belonging to the same genus are repeatedly mentioned in the text of a publication, the genus name should be written in full the first time it is mentioned, but may be abbreviated elsewhere to i

44、ts initial and followed by a dot. Abbreviations of the genus name as mentioned above shall not be used when transferring data to databases. 3.3 Author citation Since taxonomic names might have different interpretations, for publication and data storage, a name shall always (at least at its first rec

45、ord) be accompanied by the citation of the author(s), including initials, and year of publication of its original, valid description, both written in Roman type. Unfortunately, the rules of correct citation in the prevailing codes are divergent. Unlike the Botanical Code, the Zoological Code require

46、s that the year of publication is separated by a comma from the authors name. When citing a botanical name including its author, the authors name is often abbreviated. To encourage consistency the Botanical Code recommends the use of Brummitt and Powell (1992) 5, where each author of a botanical nam

47、e has been assigned a unique abbreviation. Their work is continued in the International Plant Names Index 6. For absolute clarity, the authors name(s) and year of publication should be written in full. The impact of a typing error in abbreviations is larger than in the full name. When an author deci

48、des to change the classification (and hence the name) of a taxon described previously by another author, the name of the original describing author (or combination of authors) should appear between brackets in the final combination. In botanical taxa this is followed by the name of the revising author(s) and year of publication. Both taxon names are now considered synonyms; the original name-bringing synonym is generally called basionym. In general, the name (or combination of names) of the au
