Fig. 4. Magnetic bearings plotted relative to shore direction after housing in outdoor tanks under long-wavelength light (data from Table 1). (A) Magnetic bearings of newts housed under long-wavelength light and tested under full-spectrum light failed to show a significant direction of orientation relative to shore (8°, r=0.11, P>0.10). (B) The same was true of newts housed and tested under long-wavelength light (76°, r=0.04, P>0.10). Diamonds represent newts collected in ponds to the east-southeast (ESE) of the testing site, and circles represent newts collected from ponds to the south-southwest (SSW) of the testing site. NS, not significant.
