Sensory systems evolve and enable organisms to perceive their sensory Umwelt, the unique
set of cues relevant for their survival. The multiple components that comprise sensory …

G protein-coupled receptors (GPCRs) play a crucial role as membrane receptors, facilitating
the communication of eukaryotic species with their environment and regulating cellular and …

Cetaceans are fully aquatic mammals that descended from terrestrial ancestors, an iconic
evolutionary transition characterized by adaptations for underwater foraging via breath-hold …

Visual systems adapt to different light environments through several avenues including
optical changes to the eye and neurological changes in how light signals are processed and …

Photic niche shifts of mammals are associated with changing visual capabilities, primarily
mediated by three visual pigments, two (SWS1 and M/LWS) of them for color vision and …

Animals with enhanced dim-light sensitivity are at higher risk of light-induced retinal
degeneration when exposed to bright light conditions. 1, 2, 3, 4 This trade-off is mediated by …

Amphibians are ideal for studying visual system evolution because their biphasic (aquatic
and terrestrial) life history and ecological diversity expose them to a broad range of visual …

Among major vertebrate groups, anurans (frogs and toads) are understudied with regard to
their visual systems, and little is known about variation among species that differ in ecology …

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

Abstract Changes in behaviour may initiate shifts to new adaptive zones, with physical
adaptations for novel environments evolving later. While new mutations are commonly …
