Radial axes represent direction of swimming with respect to gravity. Con- centric circles represent the percentage of total swimming movements. N gives the total number of swimming movements. HORIZONTAL means horizontally polarized light was used; the plane of polarization is perpendicular to the UP-DOWN axis. UNIFORM means the light intensities from above and from the sides were equal. CONTRAST means the light intens

HORIZONTAL means horizontally polarized light was used; the plane of polarization is perpendicular to the UP-DOWN axis. UNIFORM means the light intensities from above and from the sides were equal. CONTRAST means the light intensity from above was greater than from the sides. CONTROL group had no polariza- tion ; angular distribution of intensity had no effect on this group. ization must be present (along with a uniform angular distribution of intensity) to elicit a diurnal rhythm in the orientation behavior of these copepods. Further- more, contrast and uniform angular distributions of light intensity elicit the same response (predominantly horizontal swimming) in unpolarized light, but each elicits a different response in polarized Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
