CBE number system
Though scientific publications document sources in similar ways, the details of presenting source information vary from journal to journal. Often, publications provide prospective authors with "style sheets" that outline formats for presenting sources. Before submitting an article to a scientific publication, you should request its style sheet. Or, if one is not available, examine a copy of the publication to see how sources are listed. When writing for a science course, check with your instructor about which format to use.
Biologists, zoologists, earth scientists, geneticists, and other scientists may use an author-date system of documentation (one type of author-date system is shown in the APA documentation section of this booklet). Or they may use a number system in which each source is given a number in the text. Following the text, full publication information for each numbered source is provided in a list of references cited. Entries in this list are given in the order in which they are mentioned in the paper.
One type of number system is outlined in the CBE style manual, Scientific Style and Format, published by the Council of Biology Editors (6th ed., 1994).
In the paper, the source is referenced by a superscript number:
