Author Guidelines

Authors submitting a paper do so on the understanding that the work has not been published before, is not considered for publication elsewhere and has been read and approved by all authors.

Plagiarism Detection. Publisher is a member of CrossCheck and CrossRef plagiarism screening services. It means that all manuscripts were screened for the originality of content submitted before publication.

Please read Aims and Scope and the journal's Review Policy before submitting your manuscript.

Preparation of manuscripts.

Submission to this journal proceeds totally online. Authors are invited to submit their manuscripts as a Word document in a single file (in format and layout according Author Guidelines) that can be used by referees to evaluate the manuscript.

Manuscripts should be written in English. Authors whose native language is not English are strongly advised to have their manuscripts checked by English-speaking colleague prior to submission. English-language editing will:
· Improve grammar, spelling, and punctuation;
· Improve clarity and resolve any ambiguity caused by poor phrasing;
· Improve word-choice and ensure that the tone of the language is appropriate for an academic journal.

To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your word processor. Authors may choose to have their manuscript edited by professional English-language editing services. For the convenience of authors the following is a list of suppliers of editing services (in no order of preference):

Authors wishing to use a professional editing service should make contact and arrange payment with the editing service of their choice directly.

Note: Use of an English-language editing supplier listed here is not mandatory, and will not guarantee acceptance or preference for publication.

Formatting requirements
Use A4 paper size format; top and bottom margins – 2.5 cm; left and right margins – 2.0 cm; gutter = 0 cm. Use option “multiple pages” with value “mirror margins”. The text should be in two-column format with the following parameters: column width – 8.2 cm and spacing – 0.6 cm. Every page of the manuscript, including the title page, should be numbered. Structure and design of the Manuscript should be adjusted to the requirements presented in the TEMPLATE.

Recommended length of Research Papers should be 6–10 pages. In typing the manuscript, titles and subtitles should not be run within the text. They should be typed on a separate line, without indentation. Use lower-case lettertype.
Figures and tables should be embedded in text and placed in appropriate places.

Manuscripts should be organized in the following order:
Author’s names and affiliations
Material and Methods
Results and Discussion

Title should be concise and informative but as short as possible. Titles are often used in information-retrieval systems. Avoid abbreviations and formula where possible.

Author names and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses including the country name (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address.

Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address.

The abstract should be clear, descriptive and no longer than 1200 characters. It should state briefly the purpose of the research, describe the main objective(s) of the study, explain how the study was done, including any model organisms used, without methodological detail, summarize the most important results and their significance. An abstract is often presented separately from the article, so it must be able to stand-alone. For this reason, References should be avoided. Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.

Keywords. Up to five keywords, which are not used in the title, should be included after the abstract avoiding general and plural terms and multiple concepts. Note that these keywords will be used for indexing purposes.

Introduction should:
· Provide background that puts the manuscript into context and allows readers outside the field to understand the purpose and significance of the study;
· Define the problem addressed and why it is important;
· Include a brief review of the key literature;
· Note any relevant controversies or disagreements in the field;
· Conclude with a brief statement of the overall aim of the work and a comment about whether that aim was achieved.

References should be quoted in the text as name and year within brackets. Where reference is made to more than one work by the same author published in the same year, identify each citation in the text as follows: (Collins, 1998a), (Collins, 1998b). In case the sources include more than one researcher, two authors are cited using “,” (Deane, Jones, 2010), more than two authors are cited “et al.”: (Smith et al., 2011).

All biota should be identified by their scientific names when the English term is first used, with the exception of common domestic animals.

Material and methods. Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described. Methods sections of papers with data that should be deposited in a publicly available database should specify where the data have been deposited and provide the relevant accession numbers and version numbers, if appropriate.

Results should be clear and concise. Authors should explain how the results relate to the hypothesis presented as the basis of the study and provide a succinct explanation of the implications of the findings, particularly in relation to previous related studies and potential future directions for research.

Units and symbols. The SI system should be used for all scientific and laboratory data: if in certain instance, it is necessary to quote other units, these should be added in parentheses. Temperatures should be given in degrees Celsius.

Formulae. Use MathType to create the equation (recommended). Go to Insert > Object > Microsoft Equation and create the equation. Please confine equations to one column width and break equations at appropriate algebraic symbols. Short, one line equations, have to be vertically centred, aligned with the corresponding numbering text and punctuation signs. Give the meaning of all symbols immediately after the equation in which they are first used. Equations should be numbered serially at the right side in parenthesis.

Discussion. This should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.

Conclusions. The main conclusions of the study may be presented in a short Conclusions section, which may stand alone.

Artwork files should be in an acceptable format (TIFF, EPS, JPG) and must be supplied at the correct resolution:
· Black and white and colour photos - 300 dpi;
· Graphs, drawings, etc. - 800 dpi preferred; 600 dpi minimum.
Figures should be included in the text and numbered according to their
sequence with Arabic numerals.
Illustrations should be designed with the format of the page. The full legend should have a description of the figure and allow readers to understand the figure without referring to the text. The legend itself should be succinct, avoid lengthy descriptions of methods, and define all non-standard symbols and abbreviations. Long figure captions should be placed below the figures and justified. One line figure captions may be centred. Do not put borders around the outside of your figures. Use the abbreviation “Fig. 1” even at the beginning of a sentence.

Tables should be included in the text and numbered according to their sequence. All tables should have a brief and self-explanatory title. Footnotes can be used to explain abbreviations. Citations should be indicated using the same style as outlined above. Tables occupying more than one printed page should be avoided, if possible. Vertical lines should not be used to separate columns. Leave extra space between the columns instead. Present data with no more digits than justified by the accuracy of their measurement and no more digits than needed for the purpose of the table.

Collate acknowledgements in a separate section at the end of the article before the references. Provide here any additional information concerning research grants. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).

References should be listed at the end of the paper alphabetically on author’s names and chronologically per author. All references must be complete and accurate. Case when the reference is in other language than English, they should be transliterated to Roman script. Aside in the parenthesis should be presented translated reference in English. Where possible the DOI for the reference should be included at the end of the reference. For example: Johnson, L. B.; Breneman, D. H.; Richards, C. 2003. Macroinvertebrate community structure and function associated with large wood in low gradient streams. River Research and Applications, 19, 199–218. DOI: 10.1002/rra.712.

Online citations should include date of access. If necessary, cite unpublished or personal work in the text but do not include it in the reference list.
References should be listed in the following style:
