General information: Contributions should be written in grammatically correct English. Either British or American spelling is permitted, but one must be used consistently within a manuscript. Authors are advised to follow styles outlined in The CBE Manual for Authors, Editors, and Publishers (6th Ed., Cambridge University Press). Poorly written manuscripts will be returned to authors without further consideration.

Nomenclature of genera and species names must agree with the International Code of Zoological Nomenclature (ICZN), International Trust for Zoological Nomenclature, London, 1999; or the International Code of Botanical Nomenclature, adopted by XIV International Botanical Congress, Berlin, 1987. Biochemical nomenclature should agree with “Biochemical Nomenclature and Related Documents” (A Compendium, 2nd edition, 1992), International Union of Biochemistry and Molecular Biology, published by Portland Press, London and Chapel Hill, UK. New nucleic acid or amino acid sequences will be published only if they are also deposited in an appropriate data bank (e.g. EMBL, GeneBank, DDBJ). Except for cases where tradition dictates, SI units are to be used.

All manuscripts that conform to the Instructions for Authors will be fully peer-reviewed by members of Editorial Board and expert reviewers. The Author will be requested to return a revised version of the reviewed manuscript within four (4) months of receiving the reviews. If a revised manuscript is received later, it will be considered to be a new submission.

Copyrights: The Authors of a manuscript, accepted for publication, transfer copyrights to the publisher (Jagiellonian University). Copyrights include mechanical, electronic, and visual reproduction and distribution. Use of previously published figures, tables, or brief quotations requires the appropriate copyright holder’s permission, at the time of manuscript submission; acknowledgement of the contribution must also be included in the manuscript. Submission of a manuscript to Acta Protozoologica implies that the contents are original, have not been published previously, and are not under consideration or accepted for publication elsewhere.

Charges: There are no page charges, but Authors must cover the reproduction cost of colour illustrations (€350.00 for the first colour page, and €300.00 for every following page).


Authors should submit manuscripts electronically by e-mailing preferably as a single PDF file to the editor: Dr Krzysztof Wiąckowski, E-mail: This email address is being protected from spambots. You need JavaScript enabled to view it. . The manuscript and illustrations should be prepared in accordance with the standards of the journal (see below) except for the resolution of figures that at this stage should permit easy mailing. At the time of submission, authors are encouraged to provide names, E-mails, and postal addresses of four researchers who might act as reviewers.

When a manuscript is accepted, the final version should be submitted as one hard copy plus an electronic copy on CD. The electronic copy of the accepted manuscript should consist of a single MS Word *.DOC file (containing text and tables) with illustrations provided as separate files in appropriate graphic format and resolution (see below).


Text: The manuscript should be organized into the following sections: Title page, Summary, Keywords, Abbreviations, Introduction, Materials and Methods, Results, Discussion, Acknowledgements, References, Tables, and Figure legends. The Title Page should include the title of the manuscript, first name(s) in full and surname(s) of author(s), the institutional address(es) where the work was carried out, and page heading of up to 40 characters (including spaces). The postal address for correspondence, Fax and E-mail should also be given. Footnotes should be avoided.

Manuscripts must be double-spaced, with numbered pages (12 pt, Times Roman). When necessary, use only italic, bold, subscript, and superscript formats; do not use other electronic formatting facilities such as multiple font styles, ruler changes, or graphics inserted into the text. Do not right-justify the text or use of the hyphen function at the end of lines; avoid the use of footnotes; distinguish the numbers 0 and 1 from the letters O; avoid repetition of illustrations and data in the text and tables. Tables should be prepared with appropriate tools for tables offered by Word or Excel; do not format tables by introducing spaces and/or by right-justifying.

Citations in the text should be made by giving the author’s name with the year of publication and not by a number, e.g. (Foissner and Korganova 2000). In the case of more than two authors, the name of the first author and et al. should be used, e.g. (Botes et al. 2001). Different articles by the same author(s) published in the same year must be marked by the letters a, b, c, etc. (Kpatcha et al. 1996a, b). Multiple citations presented in the text must be arranged by date, e.g. (Small 1967, Didier and Detcheva 1974, Jones 1974). If one author is cited more than once, semicolons should separate the other citations, e.g. (Lousier and Parkinson 1984; Foissner 1987, 1991, 1994; Darbyshire et al. 1989).

References: Bibliographic references must be listed alphabetically. Use abbreviated journal names. Unpublished material, except for PhD theses, should not be included. Examples for bibliographic arrangement:

Illustrations: Line drawings should have well-defined lines and a white background. Avoid fine stippling or shading. Multiple photographs should if possible be combined into plates. Figures in the final (accepted) version of a manuscript must be in *.TIF, *.PSD, or *.CDR graphic formats only (Greyscale and Colour - 600 DPI, Art line - 1200 DPI). Do not use Microsoft Word for figure formatting. Make sure that illustrations fit within either a single column width (86 mm) or the full-page width (177 mm); the maximum length of figures is 231 mm.

Magnification should be indicated by a scale bar where appropriate. Pictures of gels should have a lane width of no more than 5 mm, and should preferably fit into a single column. Figure legends must be placed, in order, at the end of the manuscript, before the figures and must contain explanations of all symbols and abbreviations used. The figures should be numbered in the text using Arabic numerals (e.g. Fig. 1).

Disks: Please observe the following instructions when preparing the final electronic copy of the accepted manuscript on CD: (1) label the disk with your name and the manuscript code; (2) arrange the text and tables as a single MS Word *.DOC file; (3) prepare figures as separate files in appropriate graphic formats, size and resolution (as stated above); (4) ensure that the accompanying hard copy is identical to the electronic version.


After a manuscript has been accepted, Authors will receive proof sheets for correction by e-mail and will be asked to return these, preferably by electronic mail, to the editor within a week. Authors are fully responsible for any undetected errors. Only spelling errors and small mistakes can be corrected at this stage. Authors will receive ten (10) offprints free of charge as well as a locked high-quality PDF file to the use at their discretion. Additional offprints can be ordered at proofreading stage.
