“…The research concluded that variations in the geomagnetic field associated with the commencement and main phase of the geomagnetic storm led to an increase in arterial pressure of the rats with respect to the reference value derived from several control measurements when the geomagnetic field was quiet. The same results were reproduced in experiments with a simulation of the 2‐h interval of the geomagnetic storm that occurred on February 18–19, 2014, that were performed in the direction of geomagnetic H‐component [Martinez‐Breton and Mendoza, ; Martinez‐Breton et al, ].…”

“…An interesting combined study of experimentally simulated and natural geomagnetic storms was performed by Martinez‐Breton and Mendoza []. Experiments with the goal of studying the effects of geomagnetic activity on arterial pressure in rats coincided with a natural geomagnetic storm, which occurred on February 18–19, 2014 (the maximal value of Dst‐index was −116).…”

This review presents contemporary data on the biological effects of geomagnetic activity. Correlations between geomagnetic indices and biological parameters and experimental studies that used simulated geomagnetic storms to detect possible responses of organisms to these events in nature are discussed. Possible mechanisms by which geomagnetic activity influences organisms are also considered. Special attention is paid to the idea that geomagnetic activity is perceived by organisms as a disruption of diurnal geomagnetic variation. This variation, in turn, is viewed by way of a secondary zeitgeber for biological circadian rhythms. Additionally, we discuss the utility of cryptochrome as a biological detector of geomagnetic storms. The possible involvement of melatonin and protein coding by the CG8198 gene in the biological effects of geomagnetic activity are discussed. Perspectives for studying mechanisms by which geomagnetic storms affect organisms are suggested. Bioelectromagnetics. 38:497-510, 2017. © 2017 Wiley Periodicals, Inc.

“…Based on the analysis of experimental data [Krylov et al, 2014; Martinez‐Breton and Mendoza, 2016; Gurfinkel et al, 2018] and the correlations between geomagnetic indices and biological processes [Chernouss et al, 2001; Gmitrov and Gmitrova, 2004; Azcaratea et al, 2016], it was previously suggested that geomagnetic storms could be perceived by organisms as a distortion of diurnal geomagnetic variation [Krylov, 2017; Krylov et al, 2019]. In other words, the inconsistency of circadian biochemical processes synchronized with light regime and diurnal geomagnetic variation may be responsible for the medical and biological effects of geomagnetic storms.…”

Day–night cycle is the main zeitgeber (time giver) for biological circadian rhythms. Recently, it was suggested that natural diurnal geomagnetic variation may also be utilized by organisms for the synchronization of these rhythms. In this study, life‐history traits in Daphnia magna were evaluated after short‐term and multigenerational exposure to 16 h day/8 h night cycle, 32 h day/16 h night cycle, diurnal geomagnetic variation of 24 h, simulated magnetic variation of 48 h, and combinations of these conditions. With short‐term exposure, the lighting mode substantially influenced the brood to brood period and the lifespan in daphnids. The brood to brood period, brood size, and body length of crustaceans similarly depended on the lighting mode during the multigenerational exposure. At the same time, an interaction of lighting mode and magnetic variations affected to a lesser extent brood to brood period, brood size, and newborn's body length. The influence of simulated diurnal variation on life‐history traits in daphnids appeared distinctly as effects of synchronization between periods of lighting mode and magnetic variations during the multigenerational exposure. Newborn's body length significantly depended on the lighting regime when the periods of both studied zeitgebers were unsynchronized, or on the interaction of light regime with magnetic variations when the periods were synchronized. These results confirm the hypothesis that diurnal geomagnetic variation is an additional zeitgeber for biological circadian rhythms. Possible mechanisms for these observed effects are discussed.
