Journal of Biological Rhythms publishes original, full-length reports in English of empirical investigations into all aspects of biological rhythmicity particularly rhythms related to the major environmental cycles, including daily (circadian) rhythms, tidal rhythms, annual rhythms (including photoperiodism), as well as other biological rhythms that interact with those rhythms influenced by the environment. Topics include genetic, biochemical, physiological, behavioral, and modeling approaches to understanding the nature, mechanisms, and functions of biological rhythms in all species.

《生物節律雜志》用英文發表了對生物節律各方面的實證研究的原始、完整的報告，特別是與主要環境周期有關的節律，包括每日（晝夜）節律、潮汐節律、年節律（包括光周期），以及 作為與受環境影響的節奏相互作用的其他生物節律。主題包括遺傳、生物化學、生理學、行為學和建模方法，以了解所有物種生物節律的性質、機制和功能。
