Aims & scope
Journal of Circadian Rhythms is an open access, peer-reviewed online journal that publishes research articles dealing with circadian and nycthemeral (daily) rhythms in living organisms, including processes associated with photoperiodism and daily torpor.
Journal of Circadian Rhythms aims to include both basic and applied research at any level of biological organization (molecular, cellular, organic, organismal, and populational). Studies of daily rhythms in environmental factors that directly affect circadian rhythms are also pertinent to the journal's mission.
The study of circadian rhythms has experienced enormous growth in the recent past. From fungi and plants to birds and mammals, and from molecules and cells to organisms and populations, research on circadian rhythms has advanced at full speed into the 21st century. Journal of Circadian Rhythms provides the first open access journal dedicated to this expanding field.
All articles published by Journal of Circadian Rhythms are made freely and permanently accessible online immediately upon publication, without subscription charges or registration barriers. Further information about open access can be found here.
Authors of articles published in Journal of Circadian Rhythms are the copyright holders of their articles and have granted to any third party, in advance and in perpetuity, the right to use, reproduce or disseminate the article, according to the BioMed Central copyright and license agreement.
Open access publishing is not without costs. Journal of Circadian Rhythms therefore levies an article-processing charge of £1115/$1715/€1310 for each article accepted for publication. We routinely waive charges for authors from low-income countries. Generally, if the submitting author's institution is a Member the cost of the article-processing charge is covered by the membership, and no further charge is payable. In the case of authors whose institutions are Supporter Members, however, a discounted article-processing charge is payable by the author. For further details, see our article-processing charge page. A limited number of waivers for article-processing charges are also available at the editors' discretion, and authors wishing to apply for these waivers should contact the editors.

Publication and peer review process
Criteria for publication
Journal of Circadian Rhythms considers the following types of articles:
- Research: reports of data from original research and clinical trial outcomes.
- Reviews: comprehensive, authoritative descriptions of any subject within the scope of the journal.
- Debate articles - present an argument that is not essentially based on practical research. They can report on all aspects of the subject, including historical, sociological, and ethical aspects.
- Short papers - brief reports of experimental or clinical findings.
Peer review policies
- Peer review in the Journal of Circadian Rhythms is designed to ensure that the research published is "good science".
- The journal accepts articles spanning a wide range of scientific interests, as long as the results and conclusions are scientifically justified.
- Submitted manuscripts are peer-reviewed by two or more members of the editorial board or ad hoc reviewers, who make recommendations to the Editor-in-Chief.
- Electronic publication and an open access policy not only provide rapid and widespread dissemination of articles but also free the journal from page limitations. Thus, research that is well conducted but has limited interest to a wide audience at the current time can be published in the journal.
Authors will be able to check the progress of their manuscript through the submission system at any time by logging into My Journal of Circadian Rhythms, a personalized section of the site.
High-quality, bound reprints can be purchased for all articles published. Please see our reprints website for further information about ordering reprints.
