Article
Full-text available
We describe an impact of the geomagnetic field (GMF) and its modification on zebrafish's orientation and locomotor activity in a plus maze with four arms oriented to the north, east, south and west. Zebrafish's directional preferences were bimodal in GMF: they visited two arms oriented in opposed directions (east-west) most frequently. This bimodal...
Article
We exposed Daphnia magna Straus to an extra-low-frequency magnetic field (ELF MF) for several sequential generations to study its affect on size and number of nonviable individuals in Daphnia offspring produced. The lines of D. magna were subjected to ELF MF over three months. The abundance, wet biomass, and morphometric parameters were measured fo...
Article
Full-text available
Contemporary data on the orientation and navigation of animals from different taxa with the geomagnetic fields are considered in the review. The mechanisms of magnetoreception in animals are described. In this regard, several taxa of fishes are able to perceive magnetic fields via electroreceptors. A number of animals can sense the polarity of magn...
Article
Full-text available
The locomotor activity of zebrafish (Danio rerio) has a pronounced, well-studied circadian rhythm. Under constant illumination, the period of free-running locomotor activity in this species usually becomes less than 24 hours. To evaluate the entraining capabilities of slow magnetic variations, zebrafish locomotor activity was evaluated at constant...
Article
Over recent decades, changes in zebrafish (Danio rerio) behaviour have become popular quantitative indicators in biomedical studies. The circadian rhythms of behavioural processes in zebrafish are known to enable effective utilization of energy and resources, therefore attracting interest in zebrafish as a research model. This review covers a varie...
Article
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 1...
Article
Full-text available
The effect of slow magnetic fluctuations, lighting modes, and the interaction of these factors on the maturation, lifespan, brood size and the period between hatching of juveniles in Daphnia magna Straus, as well as on some morphometric parameters of the producers and offspring was studied. The lighting modes had an influence on the period between...
Article
The capability of Daphnia magna to adapt to artificial low-frequency magnetic fields via a maternal effect has been demonstrated previously. The current study assessed the possibility of a maternal effect in response to simulated natural geomagnetic fluctuations. D. magna lines were exposed to simulated geomagnetic storms for two, five, and eight s...
Article
It has been suggested that geomagnetic storms could be perceived by organisms via disruption of naturally occurring diurnal geomagnetic variation. This variation, in turn, is viewed by way of a zeitgeber for biological circadian rhythms. The biological effects of a geomagnetic storm, therefore, could depend on the local time of day when its main ph...
Article
Full-text available
A study was made of the effects that 6-and 12-h shifts in diurnal geomagnetic variation relative to the night-day light cycles exert on roach Ritulus ritulus L. embryos. Either temporal shift in diurnal geomag-netic variation stimulated blastomere proliferation and early prelarval hatching in exposed embryos compared to controls. Underyearlings dev...
Article
We have investigated a sequence of visits to arms in a cross maze in juvenile (1-year-old) roach Rutilus rutilus (L.). Fish embryos of one group are raised under a natural geomagnetic field. The embryos of another group are exposed to the main phase of a simulated geomagnetic storm (changes in geomagnetic field up to 100 nT for each component). It...
Conference Paper
Full-text available
Influence of geomagnetic field (GMF) on fish behavior is a well-established phenomenon. However, a variety of experimental devices have been used to study this phenomenon in fish making it difficult to compare results obtained by different researchers. On the other hand, plus-shaped maze is widely used as a standard device to study impacts of vario...
Article
Preferred direction of motion under influence of geomagnetic field and its modifications was registered in zebrafish (Danio rerio) raised in laboratory culture and in roach (Rutilus rutilus) from the Rybinsk Reservoir. In the geomagnetic field, specimens of zebrafish prefer two opposite directions oriented towards the north and south, while they pr...

Article
Full-text available
This study investigates the effects of lifelong exposure to reversed geomagnetic and zero geomagnetic fields (the latter means absence of geomagnetic field) on the life history of Daphnia carinata King from Australia and Daphnia magna Straus from Europe. Considerable deviation in the geomagnetic field from the usual strength, leads to a decrease in...
Article
Full-text available
Short-term impact of the low intensity electromagnetic radiation on in vitro growing Daphnia magna Straus embryos was studied. Embryos were exposed to laser radiation (633 nm, 0.05 mW/cm2) and ultraviolet radiation (365 nm, 0.16 mW/cm2) separately as well as in sequential combinations. It was shown that short-term impact of the laser radiation on...
Article
Full-text available
The influence that an induced magnetic storm (IMS) modeled in a confined volume has on the early ontogenesis of Rutilus rutilus was studied. The significant effects of the IMS were observed for the hatching rate of roach embryos, the size-weight and morphometric parameters of the fry, the variability of the vertebral column, and ontogeny stability...
Article
Full-text available
The effect of a model of the H-component of a typical magnetic storm on the early ontogenesis of Daphnia magna Straus at 21 and 23 degrees C has been studied. It was shown based on the rates of the early ontogenesis that the effects of the model magnetic storm from the sudden onset of the storm to its end differ from the effects of the model magnet...
Article
Full-text available
The influence of simulating the H component of a typical magnetic storm on the early ontogeny of Daphnia magna Straus at 21 and 23°C has been studied. Judging by the rates of early development, the effects of the whole magnetic storm experienced by the egg (from the sudden onset to the end) differ from those produced by only the recovery phase. Mor...
Article
Full-text available
Effect of the magnetic field (72.5 Hz, 150 μT), solutions of Cu2+ ions (0.01 mg/l and 0.001 mg/l) and the combined effect of these factors on the eggs of roach Rutilus rutilus was studied. Survival and hatching rate of eggs, size-weight and morphological indices of fingerlings were considered. It is shown that the direction and intensity of biol...
