For two hundred years of magnetobiological research, an extensive material on the effects of magnetic fields of different nature on live systems was stored up. Of great interest is the influence of magnetic fields on cell division in embryonic development. Morphological research including the study of the early development are fundamental because the basis of the variability of future tissues of organs, organ systems and finally biodiversity of mature organisms on the whole lays in the basis of the variability of the morphology of embryo blastomeres.
The article deals with the effect of different magnetic fields on the early
embriologenesis of Triturus Cristatus Laur. Considered the vertical sizes of left and right abdominal micromeres and left and right spinal macromeres in natural geomagnetic field and in artificially created magnetic conditions (hypomagnetic field, vertical соnstant magnetic field) have been considered.
The first division of blastomeres and their morphometry on the stage of the third division of fragmentation of caudate amphibians have not been studied enough in comparison with tailless amphibians.
Modern studies of amphibians’ cell – division morphology are an extension of classical studies and are aimed not only on identifying blastomeres symmetrical relations, but also at study of individual blastomeres descendants’ fate. Their morphological variability has been examined in artificially modified magnetic conditions compared with the magnetic field of the Earth.
The influence of the magnetic environment on the early embryo development of caudate amphibians, in addition to fundamental importance, indicate that the magnetic environment and its variability are effective environmental factor.
Keywords:the degree of variability, blastomere, the left and right abdo-minal micromere, the left and right abdominal macromere, triturus cristatus laur, biodiversity, geomagnetic, hypomagnetic and rotation of the embryos in vertical соnstant magnetic field.
