✦ Synopsis

enzyme regulating melatonin biosynthesis [11]. The melatonin synthesis is not only affected in the pineal but also in the retina itself. Comparable influences of magnetic fields on enzyme activities in the pituitary gland are not known. Therefore, a discussion on the mode of action of the disturbed MF on pigment movement within the melanophores during background adaptation remains rather speculative. In contrast to tail melanophores those in the head region have been reported not to react to local illumination [12], i.e., do not show a "primary response". The observation that the responses of the two "types" of melanophores in X. laevis tadpoles to incident light and to conditions of a disturbed MF are very different favors a working hypothesis that includes hormonal as well as direct photic mechanisms.
