GEOMAGNETIC-PULSATIONS AS ONE OF ECOLOGICAL FACTORS OF THE ENVIRONMENT

Wave processes in the Earth magnetic field are discussed from the viewpoint of their influence on the biosphere. The biogenic magnetite is a basis for magnetic field detection in biosystems. Among numerous quasiperiodical variations of the geomagnetic field there exist <<usual>> variations occuring regularly, so that the biosystems get <<used>> to them, and sporadic variations the adaptation to which is weakened. The important question in the correlation analysis is a spectral composition of the wave processes investigated, the duration of frequency components of the signal, its stability, the rate of the intensity change and the local time of occurrence.
