Acta Scientifica Naturalis strongly encourages online submissions. Once You have prepared Your manuscript according to the instructions below, please visit online submission Web site:

Please read these instructions carefully and follow them strictly. In this way You will help ensure that the review and publication of Your paper are as efficient and quick as possible.

Please send Your manuscripts to (Editor Executive) with copy to (Editor-in-Chief).

Editorial policy

All submitted manuscripts should contain original research not previously published and not under consideration for publication elsewhere. The primary criterion for acceptance is scientific quality. The papers should avoid excessive use of abbreviations or jargon, and should be intelligible to as wide an audience as possible. Particular attention should be paid to the Abstract, Introduction, Results and Discussion, Conclusion sections, which should clearly draw attention to the novelty and significance of the data reported. Failure to do this may result in delays in publication or rejection of the paper.

The texts can be published as a review, a full paper (article) or as a short communication.


Types of papers



Reviews are published by invitation only. However, a proposal for a Review may be submitted in the form of a brief letter to the Editor at any time. The letter should state the topics and authors of the proposed review, and should state why the topic is of particular interest to the field.



Whenever possible the articles should be subdivided into the following parts: 1. Front Page; 2. Abstract (written on a separate page, 200 words or less, no abbreviations); 3. Introduction; 4. Materials and Methods; 5. Results; 6. Discussion; 7. Acknowledgments (if applicable); 8. References. Articles from some areas should follow their usual format. In some cases it may be advisable to omit part (4) and to merge parts (5) and (6). Whenever applicable, the Materials and Methods section should indicate the Ethics Committee that evaluated the procedures for human studies or the norms followed for the maintenance and experimental treatments of animals.


Short communications

Short communications aim to report on research which has progressed to the stage when it is considered that results should be divulged rapidly to other workers in the field. A short communication should also have an Abstract (100 words or less) and should not exceed 1,500 words.

Tables and Figures may be included but the text length should be proportionally reduced. Manuscripts submitted as articles but found to fit these specifications will be published as short communications upon the author’s agreement.
