The Journal of Circadian Rhythms is accepting submissions for publication for 2022.

The 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, whether metabolic or behavioral. The journal includes 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.

The Journal of Circadian Rhythms is indexed in PubMed, the Web of Science/Clarivate Analytics and Scopus. JCR's 2020 Scopus CiteScore is 3.2. The journal is at the 21% (17/21) of Endocrine and Autonomic Systems journals.

The Journal of Circadian Rhythms publishes as soon as articles are ready. There is no delay in research being released. Submissions can be sent throughout the year. The journal’s average submission to acceptance time in 2021 was 77 days.

We accept online submissions via our journal website. See our Author Guidelines for further information. Alternatively, please contact the editor for more information.

Thank you to reviewers

We would like to take this opportunity to thank all of the peer reviewers who gave their time and expertise during 2021 to help ensure that the Journal of Circadian Rhythms continues to publish rigorously tested research. As always, we are extremely appreciative of the efforts put in to ensure that high academic quality is maintained.

Editor in Chief

Seth Davis, University of York, UK

Ubiquity Press would like to welcome Professor Seth J Davis, Chair of Plant Biology at the Department of Biology, University of York, as the new Editor in Chief of the Journal of Circadian Rhythms. Professor Davis is a longtime member of the Journal's editorial board.

Here are a few words of introduction from Professor Davis:

"For my Bachelors I dual majored in Microbiology and Molecular Biology with an additional minor in Chemistry. After graduation, I was thrilled to be accepted to graduate school. My dissertation research involved genetic understandings of light perception in plants to maximise growth. From there I was awarded a personal Fellowship and moved to the U.K. and I started my work on circadian-clock / climate interactions. From there I left for Germany and worked extensively on circadian clock mechanisms. This started an interest of our working group to understand how variation in clock genes provides an adaptive fitness benefit. For this we continue our work on the model dicot Arabidopsis and the model monocot barley as comparative systems to i) uncover the molecular genetic, biochemical and cellular basis of the plant circadian clock, ii) determine how the clock controls the seasonal physiology of flowering time and senescence iii) define the allelic architecture of variation in clock genes and associate those variants as quantitative trait loci in clock performance, and iv) conduct experiments on clock-defined mapping populations to learn which physiological and developmental traits are most under clock control, under a seasonal context. Collaborative work ensued on translational studies of circadian clock genes in various crops. I returned to the U.K. nearly 10-years ago now, and systems modelling is an additional method in our current clock research. I enjoy my contributions to chronobiology. Science is fun and I have always loved to communicate this with all.

My simple vision is for this journal to continue publishing high quality circadian clock studies. Descriptive, comparative and mechanistic studies are all equally welcomed for submission."

The COVID-19 pandemic has had enormous worldwide medical and economic impacts. Although it is hoped that the introduction of vaccines late in 2020 and early in 2021 will eliminate the pandemic, much can be learned from early, current, and future cases of this infectious disease.

The relevance of these events for the study of circadian rhythms is multifaceted. The lockdown imposed with the goal of reducing the spread of the virus had and continues to have an effect on how people organize their daily activities. Misalignment of central circadian rhythms related to shift work in healthcare providers likely increases their risk of coronavirus infection and leads to worse clinical outcomes. For the general population, circadian disruption caused by the lockdown and social distancing can dampen the immune system, making the virus harder to defeat. These and other connections between COVID-19 and circadian rhythms are the theme of a new special issue of the Journal of Circadian Rhythms.

We invite submissions of research articles addressing these issues. To make a contribution, please register at https://www.jcircadianrhythms.com/ and follow the instructions for article submission. Please, indicate in the cover letter (step 1) that you are submitting in response to this call. Ubiquity Press journals are eligible for fast-track peer review through a joint initiative to maximize the efficiency of peer review of COVID-19 related publications. For more information, see here.
