The CSE (Council of Science Editors, formerly the Council of Biology Editors) style is most frequently used in the fields of biology and environmental science.
The current CBE/CSE style guide is Scientific Style and Format: The CSE Manual for Authors, Editors, and Publishers, Seventh Edition (2006). Publishers and instructors who require the CBE/CSE style do so in three possible formats: a citation-sequence superscript format, a name-year format, or a citation-name format, which combines aspects of the other two systems.
In the following examples, all of which refer to environmental issues, you will see that the citation-sequence and citation-name formats call for listing the date after the publisher’s name in references for books and after the name of the periodical in references for articles. The name-year format calls for listing the date immediately after the author’s name in any kind of reference. Notice also the absence of a comma after the author’s last name, the absence of a period after an initial, and the absence of italics for titles of books or journals.

3. Journal Article CBE/CSE style uses standard scientific abbreviations for titles of journals (Am Sci for American Scientist and J Am Med Assoc for Journal of the American Medical Association, for instance). One-word titles are never abbreviated.
To cite a journal article on the Internet, add the medium ([Internet]) after the journal title, the date cited after the publication date (in brackets), and end the entry with the words “Available from:” and the URL (Internet address). Omit end punctuation after a URL (except for those that end with a slash—they end with a period).

7. E-mail Message CBE/CSE style recommends mentioning personal communications, such as letters and e-mails, in text but not listing them in the list of references.
