Seasonal Variations in Atmospheric Pressure, Partial Oxygen Density, and Geomagnetic Activity as Additional Synchronizers of Circannual Rhythms

Abstract

Abstract—The seasonal dynamics of atmospheric pressure and geomagnetic activity in the regions with different climates were analyzed to calculate the seasonal variations in the partial density of oxygen. Based on the data we obtained, an attempt was made to explain possible causes and mechanisms of synchronization of circannual rhythms under standard laboratory conditions. Analyzing our data and that of other researchers, we concluded that the atmospheric pressure and the partial density of oxygen can be considered as additional synchronizers of the organismal circannual rhythms since these parameters are characterized by the explicit seasonal dynamics. It was also shown that mechanisms exist that are responsible for the involvement of these meteorological factors in the process of synchronization of biological rhythms.
