Preparing manuscripts for submission

manuscript text

Manuscripts must be:
  • written in English with American spelling and correct grammar and punctuation;
  • in 12-point type, double-spaced throughout, including the References section, appendices, tables, and legends;
  • marked with consecutive page numbers, beginning with the cover page.

Write out numbers nine or less except as part of a date, a fraction, a percentage, or a unit of measurement. Use Arabic numbers for those larger than nine, except as the first word of a sentence. Use abbreviations of the units of measurement when they are preceded by a number: 3 min but several minutes. Write percent as one word, except when used with a number. To indicate temperature in centigrade, use C. Italicize names of organisms only when the species is indicated: Neurospora, but Neurospora crassa or N. crassa. In text citations include both names for citations with two authors. In citations with three or more authors name the first author with et al for the other authors. Cite only articles that are published or in press. Do not cite PhD theses, other dissertations, and, in general, publications that are impossible to obtain by the future readers of your manuscript.
Maydica is striving for scientific excellence to be made available to the international scientific community. Therefore, the citation of articles in languages other than the English language should be avoided.
Submit papers as standard wordprocessor or plain text files. Microsoft word files are prefered. Do not supply papers in other formats such as PDF. The total of tables + figures should not exceed a total of six units. Further tables and/or figures should be considered and signed as supplementary and will not appear in the type-set article. Papers of five type-setted pages or less will be considered short communications. Research articles should contain the following sections: Abstract, Introduction, Materials and Methods, Results, Discussion, and References. The Results and Discussion sections can be combined when needed. An Acknowledgements section can be added when requested for. Review articles should contain the following sections: Abstract, Introduction, and References. Further sections can be added when needed and as the authors retain necessary.
The first page should contain:
  • a concise, informative title that includes the name of the organism under study;
  • the authors' names (first name + surname);
  • the authors' institutional affiliations, including department; institution, city, state or province, country, and postal code.

For the authors' names, indicate different affiliations with superscript numbering. Use a superscript symbol to indicate the corresponding author and supply this authors's e-mail address to be inserted into a dedicatory footnote.

The second page contains:
  • a short running title of about 35 characters, including spaces,
  • up to five key words or phrases,
  • the corresponding author's name, mailing address including street name and number, phone and fax numbers, and email address.

Abstracts are a single paragraph, must be fewer than 250 words, and may not contain citations or abbreviations. The abstract must contain the full name of the organism studied. It should be written for people who may not read the entire paper, so it must stand on its own. The abstract should begin with a broad context of the study, followed by the core findings, results, and conclusions.
In the introduction, the scope and impact of the work should be clearly stated. A general background on the importance of the study should be provided in a single, well-reasoned paragraph near the beginning of the introduction. Successive paragraphs should contain more specific important background information, including relevant review papers and similar work in other organisms.
Materials and Methods
Manuscripts should contain a clear description of the experimental design in sufficient detail so that the experimental analysis could be repeated by another scientist. It is important to indicate what statistical analysis has been performed, including the method and model applied.
Results and Discussion
The results and discussion should not be repetitive. The results section should give a factual presentation of the data and all tables and figures should be referenced. The discussion should not summarize the results but provide an interpretation of the results, and should clearly delineate between the findings of the particular study and the possible impact of those findings in a larger context. It is sometimes acceptable to combine results and discussion.
The References section lists only articles that are published or in press. References should be formatted as they appear in a recent issue of Maydica. References are chronologically cited in text. Order references alphabetically by first author. For multiple citations with the same first author, first list single-author entries by year using 1996a, 1996b, etc., then list multiple-author entries alphabetically by second and succcessive authors.

Figures include drawings, graphs, complex chemical formulas, and other sketches. Each figure should be supplied in an independent file, which must be no larger than 10 MB.
Acceptable file formats are:
  • TIFF (.tiff)
  • JPEG (.jpg)
  • EPS (.eps)
All files must conform to these resolution ranges:
  • Halftone (color or black & white): 300 dpi
  • Grayscale and color combination images: 300-600 dpi
  • Line art images: 500 dpi

RGB, CMYK, and Grayscale are all acceptable. Halftones should be high contrast with sharp detail. For figures with multiple parts use A, B, etc. in non-bolded type to label the parts for easy reference within the text. If a figure has important areas, arrows or numbers can be used to draw attention.
Label all figures in numerical order with Arabic numerals, and cite figures in the text in their numerical order. Within the label, be sure to distinguish between similar characters, such as the letter l and the number 1. Do not insert figures within the main text. Supply all legends to figures in a single separate text file. Do not supply the legends as part of the image file. Figure legends should be a self-contained description of the content of the figure and should provide enough detail to fully understand the data presented. Figure legends should start with a brief title.
Supply all tables in a separate file. Each table should contain a short heading and can eventually contain footnotes. Do not insert tables within the main text. Label all tables in numerical order with Arabic numerals, and cite tables in the text in their numerical order.

Supplementary Data

Supplementary data, which will be available on-line only together with the published article, must be provided during submission as additional tables and/or figures. Labeling should be in numerical order with Arabic numerals. Label supplementary tables with the prefix S_table and supplementary figures with S_figure.
