Fig. 1. Normalized absorbance spectra for the visual pigments of L. rubidus based
on the Bernard template for idealized spectra (see
Palacios et al., 1996) and
max values measured by epi-microspectrophotometry
(Bernard and Remington, 1991).
The identities of the pigments are indicated by color (UV, gray; B1, dark
blue; B2, light blue; LW, orange). The vertical broken lines correspond to the
wavelengths of the color stimuli used in the behavioral tests.
