Scope
Aims, scope and focus
Biological Rhythm Research is published by Taylor and Francis Ltd. and is in Zone 4 of Biology in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Circadian rhythm and melatonin, Sleep and related disorders and Sleep and Wakefulness Research, together about 44.2% of its articles. (generated from OpenAlex topic counts and CAS ranking data)
The principal aim of Biological Rhythm Research is to cover any aspect of research into the broad topic of biological rhythms. The area covered can range from studies at the genetic or molecular level to those of behavioural or clinical topics. It can also include ultradian, circadian, infradian or annual rhythms. In this way, the Editorial Board tries to stimulate interdisciplinary rhythm research. Such an aim reflects not only the similarity of the methods used in different fields of chronobiology, but also the fact that many influences that exert controlling or masking effects are common. Amongst the controlling factors, attention is paid to the effects of climate change on living organisms. So, papers dealing with biometeorological aspects can also be submitted. The Journal publishes original scientific research papers, review papers, short notes on research in progress, book reviews and summaries of activities, symposia and congresses of national and international organizations dealing with rhythmic phenomena. Peer Review Statement All submitted manuscripts are subject to initial appraisal by the Editors and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single anonymized.
