Manuscripts must be submitted in British English. Please note that poorly written manuscripts that are difficult to understand will be rejected without review. We strongly recommend that authors have their manuscripts checked by a native speaker before submission. Submit manuscripts electronically to . Files processed by a popular text editor, such as Word, are accepted. The texts must be written using a single font, for example Times New Roman, 12 pt, single spacing. No hyphenation, tabs, and extra intervals should be used. The generic and species group taxa names should be set in italics
Should be in lower case. Only scientific, geographic or person names should be with a first capital letter. Avoid abbreviations.
Authors and affiliations:
The authors are given with a complete first and last name. The full postal, e-mail address and ORCID
iD of the author(s) should follow.
Abstract and keywords:
The abstract should presents the essence of the article in a synthesised form; the length varies — up to 20 lines. After the abstract, up to 6 keywords must be written.
Except for generic and species group taxa names italics
should not be used for emphasis, and not in abbreviations such as cf., e.g., etc. Underlining of any text is not acceptable. Abbreviations should be followed by ‘.’ (full stop; for instance: cf., e.g., etc.). Note that you shouldn’t add a full stop at the end of abbreviated words if the last letter of the abbreviation is the same as the last letter of the full word (for example, you should abbreviate ‘Dr’, ‘Mr’ without full stop at the end). Use en-dash to link spans (numerals, sizes, dates and page numbers; e.g., 1981–1992; figs 1–6; pp. 31–42). Use the International System of Units (SI) for measurements. The subtitles (Introduction, Study area, Methods, Results and discussion, Conclusions, etc.) need to be on a separate line.
Citations and references:
Bibliographic sources in the text must be cited in one of the following ways: Josifov (1980); (Josifov, 1981, 1998, 2000); Josifov & Kerzhner (1995); (Josifov & Kerzhner, 1995); Golemansky et al. (1998); (Golemansky et al., 1998); (Beshovski, 1995, 2000; Golemansky, 2002; Mitov et al., 2012). In case of 3 or more authors use ‘et al.’ after the first one. The bibliographic list includes only sources cited in the text of the article and arranged in alphabetical order. If a source is written in Cyrillic, use the abstract’s title. If there is no abstract, the title should be transliterated. The source in which the cited article is published should be given transliterated if it does not have a title in Roman script. Journal names should be quoted without abbreviations. Here some samples:

Figures and tables
Figures must be submitted electronically as a separate file(s). Mark their place in the manuscript and give headings and explanations to them (these are placed under the figures). These must be preferably in TIFF (minimum width: page — 2083 px, column — 993 px) [but also JPG, PNG] or vector format (EPS, PDF). All figures should be referenced in the manuscript.
The tables should not exceed 30 lines. The table headings and their explanations should be placed on the top. Include the tables in the text file, but after the bibliographic list. Mark their place in the manuscript and give the headings and explanations to them. Lengthy datasets in ‘table’ format (spreadsheets *.xls, comma separated values files *.csv) can be published separately as supplementary files.
