Aims and scope

The Journal of Zoo and Aquarium Research (JZAR) provides a forum for publication of novel, peer-reviewed research papers, reviews, evidence-based practice articles and short reports. Through their living collections, field conservation activities and engagement with people, zoos and aquaria are uniquely placed to advance our understanding of conservation, and associated activities.

JZAR aims to support the publication of high-quality science which generates evidence to underpin the progression of zoos and aquariums, which through its application can support evidence-based decision making. Sharing this knowledge will improve the global impact of zoos and aquariums, and bring benefits to their living collection, wild nature and people.  The core values of JZAR are:

• a questioning approach, leading to scientific experimentation;
• meticulous observation, enumeration and analysis, replacing anecdotal description;
• recording and cataloguing evidence for systematic retrieval.

The Journal of Zoo and Aquarium Research (JZAR) accepts submissions undertaken in, or in collaboration with, zoos and aquariums. Through the dissemination of high-quality research, we aim to foster an evidence-based culture that supports and progresses zoo and aquarium practices—ultimately contributing to improved outcomes for animals, plants, people and the planet.

JZAR welcomes submissions from a broad range of disciplines, including:

• Pure and applied biological sciences (e.g., behaviour, genetics, medicine, nutrition, population management, and reproduction)
• In situ conservation research (e.g., socio-economic and field studies)
• Research on the evolving roles of zoos and aquariums (e.g., visitor learning, education, and marketing)

JZAR accepts four types of submission: original research, short reports, evidence-based practice articles and reviews.

Note: Single case studies or case reports in veterinary medicine are not generally considered for publication.

Publication schedule

JZAR is published quarterly at the end of January, April, July and October.

Submission guidelines

• Register and log in at jzar.org
• Submit your manuscript online.
• Indicate what type of article you’re submitting (see below).
• Submission of a manuscript will be taken to imply that the material is original and that no similar paper is being, or will be, submitted elsewhere, either in whole or substantial part (this excludes oral presentations, in-house reports, thesis or abstract publications).
• You can suggest up to four referees; however, the Editor reserves the right to choose referees other than those suggested.
• The Editors reserve the right to accelerate the publication of high-profile papers, commissioned reviews or topical papers.
• Serialised studies should not be submitted, and titles should not contain part numbers.
• Single-case studies or case reports in veterinary medicine are not generally considered for publication.

Types of paper

JZAR currently publishes four article types, all are expected to include a well-defined research question, aim and/or hypothesis, and use a robust methodology which is able to collect appropriate data to answer the research question.

Original research: a comprehensive, hypothesis driven study that addresses a novel question or provides new insights which have the capacity to be generalised and have far-reaching impacts within the zoo and aquarium profession.

Short reports: a concise summary of a study which is preliminary or narrow in scope, where a robust scientific method has been followed and reported alongside appropriately analysed data.  These articles will likely represent studies where the scope to generalise the results beyond the study subjects is limited.

Evidence-based practice articles: a structured account of a practical husbandry or management intervention within a zoo and/or aquarium, which has been appropriately monitored to evaluate the consequences in collaboration with a Zoo and/or Aquarium. The article will report empirical outcomes in a way that informs future decisions or practice.

Reviews: a new insight to a subject is provided through analysis of previously published primary empirical studies, including quantitative meta-analysis, synthesis and modelling approaches, and critical evaluations, concluding with specific application to the Zoo and Aquarium sector.

Only invited reviews will be considered: Prospective authors should email the Managing Editor (editor@jzar.org) a 300-word abstract, a list of up to 20 key references, and a cover letter outlining why the review they propose is novel, important and timely.

Please see the RUBRIC in the downloadable Author Guidelines (click this link to access these Guidelines), to help you decide which paper style best suits your submission. If a submission falls between categories, please email the Managing Editor (editor@jzar.org) for support.

If your submission doesn’t fit within the outlined paper style, it will either be declined or you will be contacted to reformat and resubmit your submission accordingly.

Manuscript preparation

Please follow the instructions below, failure to do so can delay processing submissions:

Submissions should:

• Follow instructions on word, figure and table limits, listed in the downloadable Author Guidelines (click this link to access these Guidelines).

• Use metric or SI units where appropriate: see Baron, D.N. (1988). Units, Symbols and Abbreviations. 5th edition.London: Royal Society of Medicine Series.
• Not use footnotes except to add information below a table.

At submission figures may be embedded in the text file. If the submission is accepted for publication separate high-quality files for each figure should be uploaded (JPEG, TIFF, etc.), or as Excel files.

Original research

1. Submissions should not exceed 5000 words, excluding references
2. A maximum of 5 figures and 2 tables can be included; or 4 pages of figures/table whichever is smaller. Embedded figures able tables are acceptable at initial submission, but if the article is accepted, high-resolution figures and editable tables will need to be provided.
3. Supplementary information can be included in appendices, however responsibility for ensuring these fit house style will rest with the corresponding author. The use of online repositories (e.g. Zenodo) to share additional and/or to make data open access is recommended and can be cited within your submission.
4. Abstract should not exceed 500 words, and provide a summary of the study including rationale, methods, results and conclusion.
5. Introduction should provide a rationale for the study; why is the study important, why have the methods chosen been employed; how will the current study build upon what is known in the field. The introduction should introduce the reader to the aims and context for the work to follow. This should NOT be a description of research currently undertaken in this area or a taxonomic or ecology overview – unless pertinent to the study.
6. Methods should provide ALL details required to understand how the study was undertaken and be sufficient to all the work to be replicated. For example, including the conditions under which data were collected i.e. housing and husbandry of subjects, information about participants. Take care not to repeat information described fully elsewhere, instead please cross-reference.
   • Data analysis can be a separate section or organised within the methods. Describe how data were handled and analysed. It is important to ensure that the reader can follow if raw or manipulated data (i.e. means) were then analysed, and using what software.
   • Ethics can be a separate section or organised within the methods. Detail how ethical integrity was ensured.
7. Results should be restricted to a factual account of the findings obtained and the text must not duplicate information given in Tables and Figures. Legends for Tables and Figures should be sufficiently complete that the information provided can be understood without reference to text.
8. Discussion should outline how the data collected answer the research question/ aim/ hypothesis and what this means for the study context, and specifically for the Zoo and Aquarium sector.

4. Background should provide a description of the ‘practice’ (intervention) which is the focus of the article, including the extent to which the ‘practice’ is implemented: is this a novel practice or undertaken only in your institution, several, and/or common amongst many. A rationale should be developed which outlines the necessity of the ‘practice’ and, if already implemented, how – including specific details about whether this might vary within or between institutions. There should be a critical discussion of the evidence (and type) currently available which underpins the practice should be critically evaluated and the type of evidence needed to progress practice identified.
5. Action should briefly describe situation, including typical management (if appropriate). Give full details of the practice implemented and how evidence was collected to evaluate it; including dates if possible. Provide specific details, about implementation and monitoring of the practice so others could replicate both. Consideration of how practice and monitoring were integrated into institutional operations, including resources (i.e. time taken and costs incurred) would be useful.  
6. Consequences should summarise the evidence collected and how it progresses understanding of the practice; does this evidence concur, contradict or extend knowledge? Critically discuss the type of evidence collected, and the extent to which practice could or should be changed – and/or highlight what additional evidence is now needed to support the implementation of this practice. Comment on whether the evidence collected has or will change practice in your institution or more widely and how this was achieved.

References

Accuracy and format of references is the responsibility of the author(s). References must be checked against the text to ensure (a) that the spelling of authors’ names and the dates given are consistent and (b) that all authors quoted in the text (in date order if more than one) are given in the reference list and vice versa.

In the text, references must be arranged chronologically with the surname(s) of the author(s) followed by the date, with multiple references separated by semicolons (e.g. Pullen 2004; O’Malley 2025). For more than two authors, give the name of the first author followed by et al. and the date (e.g. Meireles et al. 2025). Use a, b, etc. after the year to distinguish papers published by the same author(s) in the same year (e.g. Miereles et al. 2025a and Miereles et al. 2025b). For two authors, use both names and the year, use and rather than & (e.g. Steinmetz and Zimmermann 2011).

In the reference list, citations must be arranged first alphabetically under author(s) name(s) and then in chronological order if several papers by the same author(s) are cited, and all authors names should be included Journal titles should be in full, not abbreviated, and italicised. Use En Dash, not hyphen, to separate page numbers. The reference list must be in JZAR format (including the use of punctuation) please see examples below.
