Structure of a Research Article

Headings and Subheadings

• Main section headings use Times New Roman, 10 pt, bold, uppercase, and centered.

• Unit abbreviations such as g, mg, kg, mL, and L are not followed by a period.
• Negative indices such as m⁻², L⁻¹, and h⁻¹ are preferred where appropriate.
• Express fractions as decimals and use the symbol “%” instead of spelling out “percent.”

• Three or more authors: use the first author’s surname followed by et al., for example Balagadde et al. (2008).
• Unpublished data and personal communications should be cited only in the text and should not appear in the reference list.
• At least 80% of references should preferably be scientific journal articles published within the most recent five years, except where older foundational literature is scientifically necessary or for taxonomic studies.
• Authors are encouraged to use a reference manager such as Mendeley, Zotero, or EndNote.
