Sensory perception is of crucial importance for animals to interact with their biotic and abiotic
environment. In amniotes, the clade including modern mammals (Synapsida), modern …

Maximum likelihood codon substitution models have proven useful for studying when and
how protein function evolves, but they have recently been criticized on a number of fronts …

Studies of cichlid evolution have highlighted the importance of visual pigment genes in the
spectacular radiation of the African rift lake cichlids. Recent work, however, has also …

Cichlids encompass one of the most diverse groups of fishes in South and Central America,
and show extensive variation in life history, morphology, and colouration. While studies of …

Most diurnal birds have cone-dominated retinae and tetrachromatic colour vision based on
ultra-violet/violet-sensitive UV/V cones expressing short wavelength-sensitive opsin 1 …

Motivation: In recent years, there has been an increasing interest in the potential of codon
substitution models for a variety of applications. However, the computational demands of …

Rhodopsin, the light-sensitive visual pigment expressed in rod photoreceptors, is
specialized for vision in dim-light environments. Aquatic environments are particularly …

The nocturnal origin of mammals is a longstanding hypothesis that is considered
instrumental for the evolution of endothermy, a potential key innovation in this successful …

The visual system in the colorful cichlid fishes from the African great lakes is believed to be
important for their adaptive radiations. However, few studies have attempted to compare the …

Rhodopsin (rh1) is the visual pigment expressed in rod photoreceptors of vertebrates that is
responsible for initiating the critical first step of dim-light vision. Rhodopsin is usually a single …
