Variability of Abdominal Left and Right Microand Macromeres of Triturus Vulgaris Embryos in Natural and Artificial Magnetic Conditions
The article deals with the effect of different magnetic fields on the early embriologenesis of Triturus Vulgaris. Vertical sizes of left and right abdominal micromeres and macromeres in natural geomagnetic field and in artificially created magnetic conditions (hypomagnetic field, vertical magnetic field) have been considered. Modern studies of amphibians’ cell - division morphology are an extension of classical studies aimed at identifying blastomeres symmetrical relations and studying 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, indicated that the magnetic environment and its variability are effective environmental factor.
