Submission Guidelines

The Proceedings of the Academy of Natural Sciences accepts papers in the areas of systematics, taxonomy, evolution, biogeography, and ecology. Certain specialized historical reviews are also considered. After preliminary review by the Managing Editor, papers will be sent to peer reviewers.

(This information may also apply to the occasional serials of the Academy: Monographs, Special Publications and Notulae Naturae. Contact the Managing Editor regarding submissions to these series.)

What to Submit

Electronic files of the manuscript and all illustrations must be submitted to the editor via email attachment, FTP site or CD. Paper copies are not needed. The manuscript file must be arranged in the following order: abstract, full text, acknowledgements, literature cited, tables, figure legends. Large tables may be submitted as separate files. “Word”; software or RTF format files are preferred. All illustrations must be separate from the text. For screening and review purposes submit illustrations as jpg (jpeg) or tif or PDF format files; images may be 300 dpi and 4 - 5 inches in maximum dimension. Higher resolution image files will be requested for manuscripts accepted for publication. Also include the names and addresses of three potential peer reviewers; include their e-mail addresses if available. Manuscripts that do not comply with the specifications listed here and below will be returned to the author.


Manuscripts must be in English; multi-lingual abstracts are permitted when necessary.

Typewritten manuscripts will not be accepted. No material shall be handwritten.

Manuscripts must be double-spaced, in any clear printing font. Leave adequate margins of at least 1 inch, or 3.5 cm, on all sides. If “A4” or another paper size not standard in the U.S.A. is used, leave at least 2 inches (or 5 cm) of space at the bottom of each page. (Standard USA size is 8.5 x 11 inches.)


Do not incorporate illustrations in the text of the paper. Printed versions of all illustrations must accompany the manuscript. Do not submit any illustrations electronically at this time. Xerographic copies of illustrations may accompany the review copies of the manuscript only if they adequately and clearly show all pertinent information. Otherwise, photographic reproductions of illustrations must accompany each copy of the manuscript.

All original artwork and photographs should be in the form of glossy prints of professional quality. Line illustrations may be produced from a high-density laser printer only if they are clear and of professional quality. Illustrations should be proportioned to fit one or two columns on the printed Proceedings page. The maximum block sizes are (width x height): one-column illustration--2.8 x 8.6 inches (7.1 x 21.8 cm); two-column illustration--5.9 x 8.6 inches (15.0 x 21.8 cm). Adequate space should be subtracted to accommodate a figure legend beneath each figure, if possible. Labelling on an illustration must be of professional quality, using a font and size that will be clear and aesthetically pleasing particularly if it is to be reduced in size for publication. Typewritten labelling is not acceptable.

Color illustrations are acceptable, but all costs incurred in preparing them for publication and in printing them must be paid for by the author.


Do not incorporate tables into the text of the manuscript. Each table must be separate. Each table must begin on a new page. If a table is wider than one page, its manuscript form must be taped and folded so that the table forms a contiguous whole.

Literature Cited

All journal and book titles must be spelled out in full. No journal-title abbreviations are allowed. For bibliographical style, follow the following formats. Note that italics are used only for scientific names and to indicate individually authored papers in a longer, edited volume.

Follow these formats when citing references in the text:

Amossé (1941)

Klee et al. (1990)

Stoermer and Tuchman (1979)

(Amossé, 1941; Klee et al., 1990; and Stoermer and Tuchman, 1979)

Use “et al.” when the reference has three or more authors.

Types and Nomenclatures

Type specimens for new taxa must be deposited in a recognized repository prior to publication. Data to this effect must be included in the text. All pertinent articles of the most recent editions of the respective international codes of zoological or botanical nomenclature will be followed.

Accepted Papers

The final, revised version of manuscripts accepted for publication must be submitted in an electronic format. Specifications will be communicated to the author upon acceptance of a paper for publication. Page charges in the amount of $40.00 per printed page will be assessed to the author submitting the manuscript.

The final format of text and illustration layout will be edited to conform to Proceedings style.

Authors will receive page proof, and may also be queried by the editor during the initial stages of editing. Significant alterations made after page proof is received will be charged to the author and may result in postponing the publication of the paper. All offprints and copies of the completed whole publication are ordered at the author's expense.
