Ectothermic vertebrates can exhibit chromatic adaptation to the environment. The aim of this work was to characterize the rhythm of color change of the amphibian Bufo ictericus, submitted to different photoperiodic regimens, as quantified by skin reflectance values. Adult males were maintained under a 12:12 Light/Dark (LD) cycle during seven days before every experiment. During the experiments, animals were kept in individual boxes for 8 days, under the following photoperiodic regimens: LD 12… CONTINUE READING
