Author Guidelines
Manuscript Types
The Thailand Natural History Museum Journal (THNHMJ) publishes three types of articles, including original research articles, short communication, and review articles.
Original Articles. Original articles present original findings based on investigations or study conducted by the authors. These articles address a specific research question or hypothesis. An original article should include sections: abstract, introduction, materials and methods, results, discussion, conclusion, acknowledgements, references, and declaration of Generative AI and AI-assisted technologies in the writing process. The total length of the manuscript, including references, table, and figure is not limited.
Short Communications. Short communications follow the same format as original articles, but with less extensive results and discussion. Acceptance remains subject to the reviewers' evaluation.
Review Articles.Review articles provide an overview of a specific topic by synthesizing evidence from published studies, guidelines, and policy documents. These articles explain key concepts, critically evaluate the current state of knowledge, and identify gaps in natural science information. The total length of the manuscript, including references, table, and figure is not limited.
Manuscript Preparation
The manuscript must not have been submitted or published in any peer-reviewed journal. Manuscripts submitted for THNHMJ must be in Microsoft Word file format on an A4 size and the text should be in Times New Roman font size 12, and double-spaced. The manuscripts must be uploaded onto the ThaiJO submission system.
The submission of a manuscript requires the consent of all co-authors and a guarantee that the content, figures, and tables do not violate copyright laws.
Supplementary files typically contain additional materials that support the main text but are not essential for understanding the primary findings. These may include:
- Raw Data: Datasets, spreadsheets, or code used for analysis.
- Extended Methods: Detailed experimental procedures beyond those included in the main text.
- Additional Figures/Tables: Extra visualizations, charts, or large data tables.
- Multimedia Files: Videos, audio recordings, or high-resolution images.
Supplementary Text: Extended discussions, literature reviews, or additional interpretations.
Manuscript Formatting
1. Title
The title should reflect the main issue of the research. It should be concise and no longer than 3 lines on an A4 page. The title must be written in lowercase, except for the first word and proper nouns, which start with a capital letter.
2. Authors, Affiliations, and Corresponding Author
The full names of all authors, including their middle name(s) and surname, along with their affiliated institutions, should be listed. The author’s names must start with a capital letter, be formatted in bold, and appear on the same line, separated by commas (,), with "and" before the last name, and superscript numbers placed after the surnames to indicate affiliations.
Affiliations represent direct contact addresses for authors, which should be postal addresses associated with their respective institutions or organizations. If an author is not affiliated with any institution, a residential address is permissible.
The corresponding author appears after the affiliations, displaying the name and email address.
3. ABSTRACT
The abstract summarizes the introduction, methodology, and discussion of the findings. It must be structured and should not exceed 350 words.
4. Keywords
Authors must provide 3 to 5 keywords that accurately reflect the core content of the manuscript, placed directly below the abstract.
5. INTRODUCTION
This section describes why you conducted your study. The authors should present the rationale for this research, review relevant literature, and highlight key research gaps. The objectives may also be outlined in the “introduction”.
6. MATERIALS AND METHODS
This section describes how you conducted your study. This section would provide enough information to allow someone in a similar field works what you did. Authors must describe the study area, potentially incorporating illustrative figures or maps. The methodology should be detailed comprehensively to enable replication by readers. For taxonomic studies, the legal provenance of the specimens must be explicitly declared. Lastly, the authors must specify the methods used for data analysis.
7. RESULTS
This section describes what your study found. Key results from the analyses which support the conclusion and recommendation should be reported. We strongly encourage using tables and figures to display your findings. We recommend that the study results be aligned with the objectives and methodology.
We have several requirements regarding the taxonomy work as follows:
• We understand that the author’s name of an animal species is not part of its scientific name. However, when mentioning a scientific name for the first time in an article, the author's name should be included. The words "and", "&", or "et" between author names may be used according to the author's preference, provided that the usage remains consistent throughout the entire manuscript. For subsequent mentions, the genus name may be abbreviated. Italicize the names of genera, subgenera, and species.
• In botany, the author’s name is part of the scientific name. Verify the accuracy of author names against the original description. The ampersand (&) is used between joint author names, and the genus name can be abbreviated upon subsequent mentions.
• When describing a new species in the article, the abbreviation "sp. nov." must immediately follow the new name (e.g., Calyptomyrmex troglodytes sp. nov. or Calyptomyrmex troglodytes Chayakul and Jaitrong, sp. nov.).
• Descriptions of new taxa and taxonomic revisions must comply with ICBN or ICZN guidelines.
• Minimize the use of acronyms in the article. State the full term first, followed by the abbreviation, before using the acronym in subsequent references.
8. DISCUSSION
This section explains the findings of your study. You should not repeat your findings here - just refer to them as needed to discuss them.
• Summarize the key findings
• Linkage of overall results with the objectives
• Interpret each of your results
• Compare your findings with literature. Agree or disagree? If disagree, explain why
• Significance of findings
Notes: Results and discussion can be reported in the same session.
9. CONCLUSION (If available)
The author should conclude the results and recommendations following the objectives stated in the manuscript.
10. ACKNOWLEDGEMENTS
The author should acknowledge anyone or any organizations that provided assistance in their work. The acknowledged person(s) should not be on the author list of the manuscript.
Ethical Approval should be addressed in “ACKNOWLEDGEMENTS” session and should clearly state the name of the ethics committee, protocol number, and approval date.
11. REFERENCES
Only published or in-press works should be included. Dissertations and non-serial conference proceedings should be treated as books. References should be cited in the text as follows:
• Jaitrong (2015) for single author
• Jaitrong and Ted (2016) for dual authors.
• Jaitrong et al. (2023) for three or more authors.
• In parentheses: (Jaitrong, 2015; Jaitrong and Ted, 2016; Jaitrong et al., 2023).
With using “and” instead of “&” and “et al.” must be italic.
