The spectral sensitivities of avian retinal photoreceptors are examined with respect to
microspectrophotometric measurements of single cells, spectrophotometric measurements …

The relative abundance and topographical distribution of retinal cone photoreceptors was
measured in 19 bird species to identify possible correlations between photoreceptor …

Many coral reef fish are beautifully coloured and the reflectance spectra of their colour
patterns may include UVa wavelengths (315–400 nm) that are largely invisible to the human …

Despite major differences between human and avian colour vision, previous studies of
cuckoo egg mimicry have used human colour vision (or standards based thereon) to assess …

We studied the optical microhabitat use and visual pigment variation among a group of
closely related teleosts (surfperch: Embiotocidae) living along the nearshore central …

It is well established that ultraviolet sensitivity plays an important role in the visually guided
behaviour of birds. From a foraging perspective, evidence now exists that ultraviolet …

We have developed a charge-coupled-device (CCD)-based microspectrophotometer (MSP)
system and provide the first report on the successful employment of this technology to …

Geographic variation in selection pressures often result in morphological or behavioral
differences among populations. In chuckwallas, Sauromalus obesus, populations differ in …

In this dissertation I investigate mate choice in the house wren (Troglodytes aedon,
Troglodytidae). I hypothesize that certain males, which are mated to polygynously, differ from …

The opsin genes of mammals have been the subject of a number of studies. As a useful
comparison and to increase our understanding of gene regulation, spectral tuning and …
