Four Style tips for presenting scientific names of organisms in academic writing

4 Style tips for presenting scientific names of organisms in academic writing

Because quantification – counting and measuring – is significant in science and inseparable from research, rigid rules and conventions have evolved for voicing measured quantities in the form of Le Systeme International d’Unites (SI). An identically elaborate and rigid system, or a group of systems, governs the naming of organisms. These systems are usually referred to as codes of nomenclature, such as the International Code of Zoological Nomenclature, the International Code of Nomenclature of Bacteria, and the International Code of Nomenclature for algae, fungi, and plants. This article covers the Four basic points of style applicable to all names.

The names of species are commonly used in most research papers. These names, always in Latin, consist of two parts (hence the term binomial); for example, Oryza sativa  for rice (Oriza is Latin for rice, and sativa means cultivated) or Homo sapiens for humans (Homo is Latin for man and Homo sapiens means the wise man). The very first part, Homo, is a noun and the 2nd part, sapiens, is an adjective that modifies the very first part. Therefore, the 2nd part is known as the specific epithet. 

Let us take a look at the basic points of style authors should be aware of while using names of species:

1. Capitalization: The very first part names the genus and always starts with a capital letter whereas the 2nd part names the species and never starts with a capital letter. 
Authors should note that the single letter is followed by a dot (e.g. T. turgidum), and Microsoft Word, assuming that dot to be a utter point (period), automatically switches the next letter to its capital form. However, names of species are never capitalized. Whether such single-letter abbreviations can begin a sentence is a point of style that varies from journal to journal: some journals find it acceptable whereas some journals require the name of the genus to be spelt out in utter even when it has been spelt out earlier.

Two. Italics: Albeit these binomials are printed in italics, it is useful to recall that the italics are to differentiate the names from the surrounding text: if the surrounding text is italicized, the names are printed in the normal, upright form. 

Three. Abbreviations: It is common to give the accomplish binomial at the very first mention and then onwards abbreviate the name of the genus to the initial letter, as in ‘The most commonly grown species of wheat is Triticum aestivum, or common or bread wheat. Macaroni wheat is T. turgidum and emmer wheat is T. diacoccum.’ 
A paper may discuss species that belong to different genera, and some genera may happen to have the same initial letter, as in Solanum tuberosum (potato) and Sorghum bicolor (sorghum, a millet). Albeit some codes permit a genus name to be abbreviated using a 3-letter version, Scientific Style and Format specifically discourages this practice [1, p. 379].

Four. Referring to unspecified species. At times, it is necessary to refer to one or more species without specifying the exact species i.e. without providing the 2nd part of the binomial. In such cases, the customary form is to use ‘sp.’ (singular) or ‘spp.’ (plural), as in ‘several Triticum spp. were compared’ or ‘the collection included two specimens of Zea mays, three of Oryza sativa, and one of Sorghum sp.’ Please note that the word thus abbreviated is not set in italics but always completes with the dot.
