Preparation of manuscripts

Sections: Manuscripts should be divided into the following sections: Title page, abstract, introduction, material and methods, results, discussion, acknowledgements, references, captions to figures, tables.

Formats and Style: Manuscripts must be written in English.  Authors not familiar with English are advised to seek the help of an English-speaking colleague. All sections of the manuscript must be typed using MS Word (or compatible), letter Times New Roman 12, double-spaced on A4 paper with 2.5-3.0 cm margins. To aid reviewers, number the lines of the text (go to files, page setup, layout, lines numbering). Pages should be numbered consecutively (at bottom right-hand corner) and footnotes must be avoided. Mark the position of each figure and table in the margin. The full Latin names -in italics- of all species used in the study must be supplied. Standard nomenclature should be used throughout. Avoid unnecessary abbreviations and symbols. Words at the end of a line should not be divided. Numbers from one to ten must be spelled out.

Length: Length of research papers hould be kept below 32 double-spaced typewritten pages. Authors should limit the number of references (maximum of 40), figures (up to 5) and tables.

Title page: The Title page contains: a) The title. It should be sort, concise and informative. b) The names of the authors and of the institution (the latter can appear in the local language).  Author’s name should be followed by his/her department, institution, city, and country. Indicate the author to whom correspondence and proofs should be addressed and supply full postal address, phone and fax numbers and e-mail address.

Abstract: The second page of the manuscript must contain only the abstract and the key words. The abstract should be a single paragraph not exceeding 250 words and stating the main points. Non-standard abbreviations and reference citations should be avoided.

Key words: Up to eight key words, which may or may not appear in the title, should be listed in alphabetic order after the abstract.

Tables: Each table, including headings and legend (at the top), should be on a separate page. Number tables consecutively using Arabic numerals. Do not duplicate information in the text or data presented in graphic forms. Very long tables are discouraged and very short ones should be combined, when possible. Insert rules at the head, below column headings and foot of each table.

Figures: Photographs, charts and diagrams (limited to 6) are to be referred to as “Figures” and should be ordered consecutively. Figures should not be regarded as mere illustrations but restricted to  the minimun needed to clarify the text.  They should not duplicate information found in tables. Include Figure number, titles and explanatory legends for all illustrations on a separate sheet placed before the figures. Label multipart figures with consecutive letters of the alphabet. Line drawings should be intensely black on white. Halftones must be submitted as photographs with good contrast and sharp focus throughout. Avoid small dotted lines, shading, and stippling, which do not reproduce well. Be certain that symbols and lettering will be legible after reduction.

References: All publications quoted in the text should be presented in alphabetic order in a list following the manuscript. In the text refer to the author’s name and year of publication (i.e. Costa (1999) or (Costa, 1999)). For two authors, use the ampersand (&); for more than two authors the name of the first author should be followed by “et al.”. References cited together in the text should be arranged chronologically. The List of references (on a separate sheet) should be arranged alphabetically on authors’ names, and chronologically per author. Names of all authors must be included. Publications by the same author(s) in the same year should be listed as 2000a, 2000b, etc. Unpublished work will not be listed in this section unless it is “in press”.
