General

The Annals of Tropical Research (ATR) publishes original research papers, review articles, research notes, conference proceedings and letters to the editor that have not been published before, submitted to other journal or under consideration for publication elsewhere.

Manuscripts should be written in English and typed double spaced on one side of A4 (29.7cm x 21cm) or short bond (28cm x 21.6cm) paper, with wide margins, using Arial 12 points. All pages should be numbered consecutively on the top right corner, including those containing tables and figures. Research papers should not exceed 7,000 words in length; research notes, 2,000 words; letters, 1000. Abstract, keywords, tables, figures, footnotes, references and supplemental materials are included in the word count.

All manuscripts are reviewed by at least two referees prior to acceptance under a double-blind review process where both authors and reviewers are kept anonymous.

Manuscript Structure

All manuscripts must follow the ATR house style. Manuscripts that do not conform to the ATR house style may be rejected. Click this link for detailed presentation of the ATR house style: (Click here).

The first page should contain the title of the paper and the names of the authors. The title of the paper should not exceed 100 characters including spaces. The organizational affiliation of the authors and the telephone and fax numbers and e-mail address of the corresponding author should be indicated as footnotes.

The second page of the manuscript should contain only the Title, Abstract and Keywords. The abstract should present briefly the scope, major results and conclusions of the paper and should not exceed 250 words. A list of 4 to 6 keywords should immediately follow the abstract. These words will be used for indexing so do not include words that are in the title of the paper as well as general words like “development”.

The main portion of the manuscript should start on the third page. It should be divided into the following sections: Introduction, Materials and Methods, Results and Discussion, Conclusion (and Recommendations or Implications if applicable), Acknowledgment (if any) and References. Each section may be subdivided into sub-sections. Limit subsections to three levels.

References

Only published papers should be cited as references except for theses. References should be listed in sufficient details so that they can be easily located. They should be cited in the text as follows: single author: Bacusmo (2016) or (Bacusmo 2016); two authors: Uy and Shaw (2008) or (Uy & Shaw 2008); three or more authors: Lombard et al(2002) or (Lombard et al 2002). The Latin abbreviations ‘et al’ are not italicized and ‘al’ is not followed by a period except when it ends a sentence.

References cited in text must be included in the reference list and vice versa. The only exceptions to this rule are personal communications and classical works. References must be arranged alphabetically by the surname of the first author or organizational name, or by the first word of the title if there is no author. Ignore the words ‘A’,’An’,and ‘The’ when alphabetizing by title. Two or more entries by the same author(s) are to be listed in chronological order with the earliest first. Below is ATR’s reference style.
