The Annals of Tropical Research (ATR) publishes original research papers, review articles, research notes, conference proceedings and letters to the editor.
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. All pages should be numbered consecutively on the top right corner, including those containing tables and figures.
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.
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.
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.
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 & Shaw (2008) or (Uy&Shaw 2008); three authors: first citation- Lombard, Snyder-Duch & Bracken (2002), second citation - Lombard et al (2002) and four authors or more: Kobayashi et al (2009) or (Kobayashi et al 2009). 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.

Illustrations and Tables
Figures should be of good quality and should have thickness of lines and size of lettering and other symbols to allow reduction of their original dimensions up to 50%. They must not exceed the size of an A4 or a letter- sized bond paper; explanatory notes to tables should be indicated by superscript small letters; figures and tables should be printed on separate sheets and placed after the references section (ie not inserted in the typed text). In addition, they should be provided with concise captions (above for tables, and below for figures) which adequately describe their contents. Photographs should be submitted as high-contrast glossy prints. Color plates may be included if color is necessary for clarity.
Abbreviations and Units
Only SI units and abbreviations should be used. Normal and molar concentrations should be written in italics N andM, respectively. The following standard abbreviations should also be used: mg, g, kg, km, mm, cm, m, rpm, s (second), h (hour), min (minute), l (liter), ml, m-3, kg per ha or kg ha-1 (the minus index should always be used in tables and figures). Latin biological names should be italicized or underlined. These commonly used Latin words are not italicized: a priori, a posteriori, in vitro, in utero, in situ, ad libitum, per se and viz, so as the abbreviations et al,eg,ie,etc and vs, which do not carry a period except when they end a sentence.
Twenty offprints of each published paper will be supplied free of charge. Additional copies may be ordered from the editorial office of the ATR.
Submission of a paper is understood to mean that it is original and unpublished and is not being considered for publication elsewhere. Authors may submit manuscripts online at wwww.annalsoftropicalresearch.com or as email attachment to email@example.com or firstname.lastname@example.org. Three hard copies of each manuscript may be submitted to the ATR office.
