The Dhaka University Journal of Biological Sciences publishes full papers and short communications that report original research in any area of the biological sciences and make a meaningful contribution to the field.

2. Manuscript Preparation and Submission

Manuscripts must be written in English and formatted with 1.5-line spacing and 1-inch margins on all sides. The length of full papers should be approximately 3,500 words, excluding the abstract and reference list, while short communications should not exceed 2,000 words, including tables and figures.
