Table 4 The effects of PC1, PC2, and PC3 on behavioral sensitivities to the four stimulus wavelengths of light; GLMs were generated for each wavelength using behavioral sensitivities to the stimulus wavelengths of light as response variables

From: Effects of light environment during growth on the expression of cone opsin genes and behavioral spectral sensitivities in guppies (Poecilia reticulata)
