How to format your references using the Copeia citation style

This is a short guide how to format citations and the bibliography in a manuscript for Copeia. For a complete guide how to prepare your manuscript refer to the journal's instructions to authors.

Using reference management software

Typically you don't format your citations and bibliography by hand. The easiest way is to use a reference manager:

PaperpileThe citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNoteDownload the output style file
Mendeley, Zotero, Papers, and othersThe style is either built in or you can download a CSL file that is supported by most references management programs.
BibTeXBibTeX syles are usually part of a LaTeX template. Check the instructions to authors if the publisher offers a LaTeX template for this journal.

Journal articles

Those examples are references to articles in scholarly journals and how they are supposed to appear in your bibliography.

Not all journals organize their published articles in volumes and issues, so these fields are optional. Some electronic journals do not provide a page range, but instead list an article identifier. In a case like this it's safe to use the article identifier instead of the page range.

A journal article with 1 author
Butler, D. 2003. Developing-world health: the fightback starts here. Nature 426:754.
A journal article with 2 authors
Koentges, G., and T. Matsuoka. 2002. Evolution. Jaws of the fates. Science (New York, N.Y.) 298:371–373.
A journal article with 3 authors
Savrasov, S. Y., G. Kotliar, and E. Abrahams. 2001. Correlated electrons in delta-plutonium within a dynamical mean-field picture. Nature 410:793–795.
A journal article with 13 or more authors
Albrengues, J., M. A. Shields, D. Ng, C. G. Park, A. Ambrico, M. E. Poindexter, P. Upadhyay, D. L. Uyeminami, A. Pommier, V. Küttner, E. Bružas, et al. 2018. Neutrophil extracellular traps produced during inflammation awaken dormant cancer cells in mice. Science (New York, N.Y.) 361.

This example shows the general structure used for government reports, technical reports, and scientific reports. If you can't locate the report number then it might be better to cite the report as a book. For reports it is usually not individual people that are credited as authors, but a governmental department or agency like "U. S. Food and Drug Administration" or "National Cancer Institute".

Government report
Government Accountability Office. 1997. FAA Financing: Issues and Options in Deciding to Reinstate or Replace the Airline Ticket Tax.

Theses and dissertations

Theses including Ph.D. dissertations, Master's theses or Bachelor theses follow the basic format outlined below.

Doctoral dissertation
Bradnan, D. M. 2015. Cherelle Wilt in Theobroma cacao.

News paper articles

New York Times article
Oestreich, J. R. 2017. From 1687, Early Sounds in All Their Vibrancy. New York Times:C6.

In-text citations

References should be cited in the text by name and year in parentheses:

This sentence cites one reference (Butler, 2003).

Here are examples of in-text citations with multiple authors:

  • Two authors: (Koentges and Matsuoka, 2002)
