dc.description.abstract | Examining the role of color in mate choice without testing what colors the study animal is capable of seeing can lead to
ill-posed hypotheses and erroneous conclusions. Here, we test the seemingly reasonable assumption that the sexually dimorphic
red coloration of the male jumping spider Saitis barbipes is distinguishable, by females, from adjacent black color
patches. Using microspectrophotometry, we find clear evidence for photoreceptor classes with maximal sensitivity in the UV
(359 nm) and green (526 nm), inconclusive evidence for a photoreceptor maximally sensitive in the blue (451 nm), and no
evidence for a red photoreceptor. No colored filters within the lens or retina could be found to shift green sensitivity to red.
To quantify and visualize whether females may nevertheless be capable of discriminating red from black color patches, we
take multispectral images of males and calculate photoreceptor excitations and color contrasts between color patches. Red
patches would be, at best, barely discriminable from black, and not discriminable from a low-luminance green. Some color
patches that appear achromatic to human eyes, such as beige and white, strongly absorb UV wavelengths and would appear
as brighter “spider-greens” to S. barbipes than the red color patches. Unexpectedly, we discover an iridescent UV patch that
contrasts strongly with the UV-absorbing surfaces dominating the rest of the spider. We propose that red and black coloration
may serve identical purposes in sexual signaling, functioning to generate strong achromatic contrast with the visual
background. The potential functional significance of red coloration outside of sexual signaling is discussed. | pl_PL |
