Please write your text in good English (American or British usage is accepted, but not a mixture of these). Use decimal points (not decimal commas); use a space for thousands (10 000 and above).
Should contain the objectives of the work and provide an adequate background. Avoid a detailed literature review.
MATERIAL AND METHODS
Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described.
RESULTS SHOULD BE CLEAR AND CONCISE
This should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.
The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.
ESSENTIAL TITLE PAGE INFORMATION
TITLE: This should be concise and informative.
Authors’ names and affiliations: Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript number immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name, and, if available, the e-mail address of each author.
CORRESPONDING AUTHOR: Clearly indicate who is willing to handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that the telephone number is provided in addition to the e-mail address and the complete postal address.
PRESENT/PERMANENT ADDRESS: If an author has moved since the work described in the article was done, or was visiting at the time, a "Present address" may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.
A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions.
Immediately after the abstract, a maximum of 6 keywords should be provided., using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, "and", "of"). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.
Acknowledgements should be made in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).
Authors and editors are, by general agreement, obliged to accept the rules governing biological nomenclature, as laid down in the International Code of Botanical Nomenclature, the International Code of Nomenclature of Bacteria, and the International Code of Zoological Nomenclature. All crops, plants, insects, birds, mammals, etc. should be identified by their scientific names when the English term is first used, with the exception of common domestic animals.
NOMENCLATURE AND UNITS
Follow internationally accepted rules and conventions: use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI. You are urged to consult IUB: Biochemical Nomenclature and Related
DOCUMENTS: http://www.chem.qmw.ac.uk/iubmb/ for further information.
Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).
Footnotes should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many word processing packages build footnotes into the text, and this feature may be used. Should this not be the case, indicate the position of footnotes in the text and present the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.
Indicate each footnote in a table with a superscript lowercase letter.
Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the table body and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.
As a minimum, the full URL should be given. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.
TEXT: All citations within the text should follow these formats:
EXAMPLES: "as reported (Olusola, 2000a, 2000b, 2004; Mohammed and Tarfa, 1999). Uche (2008)
have recently shown ...."
LIST: References should be arranged first alphabetically and then further sorted chronologically if necessary. More than one reference from the same author(s) in the same year must be identified by the letters "a", "b", "c", etc., placed after the year of publication.
