Among vertebrates, teleost eye diversity exceeds that found in all other groups. Their
spectral sensitivities range from ultraviolet to red, and the number of visual pigments varies …

Understanding the numerous roles that colouration serves in the natural world has remained
a central focus in many evolutionary and ecological studies. However, to accurately …

Obesity is a growing societal scourge. Recent studies have uncovered that paternal
excessive weight induced by an unbalanced diet affects the metabolic health of offspring …

Males often strategically adjust the number of available sperm based on the social context
(ie sperm priming response), but it remains unclear how environmental and genetic factors …

Although biologists have described biofluorescence in a diversity of taxa, there have been
few systematic efforts to document the extent of biofluorescence within a taxonomic group or …

To convert external light into internal neural signal, vertebrates rely on a special group of
proteins, the visual opsins. Four of the five types of visual opsins—short-wavelength …

Highlights•Two metrics describing male pattern contrast were used to predict female
preference.•OPC and BSA described, respectively, whole and local pattern contrasts.•Three …

Our study assesses the variability of amphibian biofluorescence and provides insight into its
potential functions and role in anuran evolution. Via a field survey across South America, we …

The visual capabilities of fish are optimized for their ecology and light environment over
evolutionary time. Similarly, fish vision can adapt to regular changes in light conditions …

The sensory drive hypothesis predicts that across different light environments sexually
selected colour patterns will change to increase an animal's visual communication efficiency …
