How to format your references using the ZooKeys citation style

This is a short guide how to format citations and the bibliography in a manuscript for ZooKeys. 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:

Paperpile	The citation style is built in and you can choose it in Settings > Citation Style or Paperpile > Citation Style in Google Docs.
EndNote	Find the style here: output styles overview
Mendeley, Zotero, Papers, and others	The style is either built in or you can download a CSL file that is supported by most references management programs.
BibTeX	BibTeX 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

Raffaelli D (2004) Ecology. How extinction patterns affect ecosystems. Science (New York, N.Y.) 306: 1141–1142.

A journal article with 2 authors

Gilg O, Yoccoz NG (2010) Ecology. Explaining bird migration. Science (New York, N.Y.) 327: 276–277.

A journal article with 3 authors

Gravina B, Mellars P, Ramsey CB (2005) Radiocarbon dating of interstratified Neanderthal and early modern human occupations at the Chatelperronian type-site. Nature 438: 51–56.

A journal article with 4 or more authors

Christian KM, Poulos AM, Lavond DG, Thompson RF (2004) Comment on “Cerebellar LTD and learning-dependent timing of conditioned eyelid responses.” Science (New York, N.Y.) 304: 211; author reply 211.

Books and book chapters

Here are examples of references for authored and edited books as well as book chapters.

An authored book

Pagliaro M (2010) Nano-Age. Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim, Germany.

An edited book

Gadea PM (2013) Analysis and Algebra on Differentiable Manifolds: A Workbook for Students and Teachers. 2nd ed. 2013. Muñoz Masqué J, Mykytyuk IV (Eds). Springer Netherlands, Dordrecht, XXVI, 618 p pp.

A chapter in an edited book

Goldengorin B, Pardalos PM (2012) Data Correcting Approach for the Simple Plant Location Problem. In: Pardalos PM (Ed), Data Correcting Approaches in Combinatorial Optimization. SpringerBriefs in Optimization. Springer, New York, NY, 79–106.

Web sites

Sometimes references to web sites should appear directly in the text rather than in the bibliography. Refer to the Instructions to authors for ZooKeys.

Blog post

Andrew E (2014) Can Spiders Really Reach The “Size Of A Puppy”? IFLScience. Available from: https://www.iflscience.com/plants-and-animals/no-puppy-sized-spider-isn-t-photoshopped/ (October 30, 2018).

Reports

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 (1977) The SEASAT-A Project: Where It Stands Today. U.S. Government Printing Office, Washington, DC

Theses and dissertations

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

Doctoral dissertation

Molina-Gutierrez E (2009) Keys to my home: A grant proposal project. Doctoral dissertation. California State University, Long Beach

News paper articles

Unlike scholarly journals, news papers do not usually have a volume and issue number. Instead, the full date and page number is required for a correct reference.

New York Times article

Peters JF, Nikas J, Lyons E (2017) Youth in San Diego: Skateboards, Beach Hangs and Chicano Culture. New York Times: ST4.

In-text citations

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

This sentence cites one reference (Raffaelli 2004).
This sentence cites two references (Raffaelli 2004, Gilg and Yoccoz 2010).

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

Two authors: (Gilg and Yoccoz 2010)
Three or more authors: (Christian et al. 2004)
